2021第六届能源，环境与地球科学国际会议

2021年11月26-28日

In-depth understanding mechanism of global climate change is critical to achieving global carbon neutrality in the near future. The continuous convergence between Indian and Asian continents has created a growing Tibetan plateau. Rough 7 trillion tones atmospheric CO₂ were transformed as organic carbon, carbonates and carbonic magmas/fluids trapped in the Tibetan thickened crust and adjacent foreland basins, leading to glacial-interglacial climate. During the interglacial periods, the Tibetan plateau is a huge heat source, together with higher sea surface temperature, resulting in much freshwater being removed to low latitudes including the Tibet plateau. Tibet plateau thus becomes a greenly giant water tower and sequesters huge amounts of CO₂ through tectonics and plants to decline global atmospheric CO₂ concentrations greatly. During the glacial times, the Tibetan plateau is a hugely cold source that much freshwater is sent to high latitudes, e.g., transformed as ice sheets in Greenland island. The low latitudes thus become deserts. The deserted plateau releases, rather than absorb, large amounts of CO₂, resulting in global atmospheric CO₂ concentrations never below 180 ppmv and rising subsequently. Tibetan plateau has thus remained a quasi-dynamic balance of globally atmospheric CO₂ concentrations since the Miocene times. Today much freshwater is returning to inland deserted regions, especially the deserted Tibetan plateau, due to global warming triggered off by anthropic emissions. Large amounts of atmospheric CO₂ and much water are sent to Tibetan deeply broken silicates by the tectonics and plant roots, enhancing subsurface silicate chemical weathering continuously. Pedogenic carbonates and organic carbon are also continuously formed in the wetlands. These processes are always carbon unsaturation so that at least 10 billion tons/year atmospheric CO₂ are passively sequestered by the Tibetan plateau and adjacent regions in the near future based on our conservative estimates. Therefore, man-made planting wetland within Tibetan and adjacent regions is a better approach to achieve global carbon neutrality in the near future.

Prof. Dr. Yan Liu holds a Ph.D. in Tectonics from the Institute of Geology, Chinese Academy of Sciences. He is a Professor at the Institute of Geology, Chinese Academy of Geological Sciences. He has engaged in comprehensive surveys on the Tibetan plateau and adjacent regions for a long time, focusing on mass exchange between Earth’s exterior and interior and implications to global climate changes, and thus acquired several German DAAD Awards and China Tibetan Plateau Research Society Award.

演讲主题：Water Leak Control for the Oil-producing Wells Using Downhole Water Sink Technology

查看更多信息

Casing or tubing leaks cause unwanted water production from oil-producing wells. Many chemical and mechanic water control technologies can be used to solve this problem, including squeezing chemical shutoff fluids into the targeted zone or using plugs, cement, packers, patches to block the leakage. Although those methods are field-proven to be effective, the mechanical solutions may require well logs to detect the water entry point in the well. Chemical methods may present environment risks. In this study, an alternative method, Downhole Water Sink, is proposed to solve the problem of unwanted water production from a casing or tubing leak. The effectiveness of this method to control water production in a well with casing or tubing leaks is tested using the Hele-Shaw experimental model. The results show that this method can control unwanted water production via dynamic control of the pressure drawdown in the reservoir. From a technical standpoint, the advantage of this technology is that it eliminates the need to run logs to locate the water entry point and does not require chemical injection into the formation. From an environmental standpoint, this technology has the circular economy elements. Because the produced water in this technology contains little or no oil, it can be reused for reinjection into the reservoir for water flooding or pressure maintenance purposes. Therefore, a production-reinjection process to recycle the produced water is established to reduce the pollution caused by discharging the wastewater into the environment.

演讲主题：Spatial Quantitative Analysis of Urban Energy Consumption Based on Night-Time Remote Sensing Data and POI

查看更多信息

Climate change has become a major global environmental issue that is widely concerned by countries around the world. It has been a very clear scientific consensus that the global carbon emission has to be cut urgently under the context of the global warming and extreme climate. Currently, few studies on the urban energy consumption have been performed, especially the quantitative research on the scale of urban blocks, which is actually required by cities in order to adopt precise control, optimize energy structure, and reduce carbon emissions. This paper took Jingmen, a resource-based city, as a case city, and applied night-time remote sensing data, POI, and other big data. Quantitative analysis of the spatial data on key factors affecting carbon emissions in transportation, industry, and construction sectors, respectively, was applied to realize block- scale spatial visualization of urban energy consumption, and furthermore, to discuss the impact of urbanization and industrialization on urban energy consumption. It is found that the continuous growth of energy consumption in the industrial sector was the main driving factor of the city's total energy consumption growth. Among the 72 towns (blocks), 10 towns (blocks) were dominated by industrial energy consumption which accounted for up to 68% the energy consumption of Jingmen. From 2005 to 2015, the total energy consumption of Jingmen City increased by 828,200 tons of standard coal equivalent(tce), while the number of towns (blocks) with more than 10,000 tons of standard coal equivalent(tce) decreased by 4. Therefore, the energy consumption of Jingmen City showed a trend of increase and concentration. The conclusions of this study can fill up the problems that cannot be found in the energy consumption statistics of cities, and propose a more accurate way to reduce energy consumption in Jingmen City, which provide a reference for the green transformation of similar small and medium-sized resource-based cities.

Nitrogen(N) and phosphorus(P) pollution is common problem worldwide. Global N and P cycle is reshaped by human activities, especially through agricultural production. The first pollution survey in China estimated that 57% of nitrogen (N) and 67% of phosphate (P) in water bodies were from agricultural production losses. The UN Food and Agriculture Organization has listed intensive livestock and poultry farming as one of the three major sources of environmental pollution in the world. It was estimated that 551 million tons of manure (dry weight base) were generated in 2014, which contained 25.3 million tons of N, 5.2 million tons of P, and 19.4 million tons of potassium, respectively. And trend will increase even further with the expansion of the livestock and poultry breeding industry. In this speech, Professor Zhang Qingwen will introduce some researches of her team considering identification of key points in N flows in China's agricultural system using NUFER model, and the potential of crop-livestock system coupling based on land bearing capacity of cropland. Besides, the results of field experiment on gaseous nitrogen loss control and optimized nitrogen management under ICLS showed that combined application of biogas slurry and synthetic fertilizer could potentially reduce N₂O emission and increased crop yield. N management by livestock manure application in the integrated crop-livestock system(ICLS) can provide a scientific reference for achieving green and high-quality development of agriculture.

In the upper atmospheric radioactive transfer, the AGWs (atmospheric gravity waves) come from the Earth’s surface physical phenomenon upward propagating. AGWs are reflected by the variation of the upper atmospheric concentration and wind velocity. AGWs play an important role in the dynamics of the upper and middle atmosphere. In this topic, the three number densities of O2 nightglow species at the peak altitude of 94 km at Xi'an had obtained through the self-made GBAII (Ground-based airglow imaging interferometer) prototype which could obtain the O2(0-1) nightglow’s imaging interference fringes at the three local times in June.13 2012, Oct.18, 2018, and April.7 2019. And three corresponding AGWs parameters of the periods, 2 dimension wavelengths, energy flux, and momentum flux were obtained by GBAII, respectively: AGWs’ period ranges from 0.32 h to 7.05h; the meridional wavelengths range from 30.53 km to 494.90km and the zonal one ranges from 28.22 km to 610.89km; the energy flux of AGWs ranges from 0.0605m3s-3 to 60.6554m3s-3 and the momentum flux ranges from 0.0017m2s-2 to 1.5788m2s-2. The research results can provide some scarce data for O2 concentration in the upper atmosphere and related wave parameters of AGWs.

演讲主题：Achieving a Balance Between Privacy Protection and Data Collection: A Field Experimental Examination of a Theory-Driven Information Technology Solution

查看更多信息

Companies face a tradeoff between creating stronger privacy protection policies for consumers and employing more sophisticated data collection methods. We proposed an information technology (IT) solution to solve this problem, and benchmarked our solution through field experiments relative to two conventional applications. The results showed that our solution decreased privacy concerns and increased consumers’ information disclosure intentions and actual disclosure behavior. A post-hoc analysis corroborated these findings, indicating that our design enhanced perceived procedural justice, interactional justice, and distributive justice among consumers and made them feel comfortable to disclose their personal information. Likewise, companies would be able to collect additional personal information from consumers, thereby contributing to a privacy-friendly environment.

演讲主题：Implementation of the ‘Ice Silk Road Initiative’ in the Reality of the Development of Maritime Laws: Russian and Chinese Compared

查看更多信息

“Ice Silk Road” as a joint Sino-Russian project was designed to promote the unification of the strategic initiatives of the two countries and the development of comprehensive cooperation between Russia and China in the Arctic. Technically, “Ice Silk Road” means the shortest route from the Pacific Ocean to the Atlantic Ocean through the Northern Sea Route in the Arctic; it requires the development of the infrastructure of the Northern Sea Route and the organization of cargo transportation along it. Both sides – Russia and China – had demonstrated a strong interest in the “Ice Silk Road” implementation and the development of merchant vessels navigation in the frame of it. Implementation of any modern political initiative needs a ground of legal instruments and well-established mechanism of their use; in case of joint political and economic initiative’ implementation, such instruments shall be compatible or at least complimentary. This article analyses the development of the two laws of a paramount importance for Russia and China in the field of merchant shipping, namely the Maritime Code of China of 1992 and the Russian Merchant Shipping Code of 1999. The article expounds the status and significance of both maritime laws in the legal systems of the country of origin, analyzes the historical process of these laws’ formation and revision, outlines some important results of the Codes’ revision and points out most probable directions of their further development to become a legal support for mutual efforts of Russia and China to ensure the Northern Sea Route’s efficiency in the frame of the “Ice Silk Road” Initiative.

The purpose of this study was to ascertain whether there exist differences in the impact of social media use on anxiety and depression among Chinese and International students in China during the peak of COVID-19. A structured online questionnaire was distributed among Chinese and International students across China, based on modified instruments from the generalized anxiety disorder 7 (GAD-7), the Patient Health Questionnaire 9 (PHQ-9), and social media use. Three hundred and ten (310) responses from Chinese students and 474 from International students were further analyzed using the Partial Least Squares based on structural equation Modelling (PLS-PM). This study found a significant negative relationship between social media use and anxiety (= -0.382, p<.001) and social media use and depression (= -0.134, p< .001) among Chinese students. Similarly, a significant negative relationship was observed between social media use and anxiety (= -0.381, p<.001) and social media use and depression (=-0.390, p< .001) among International students. This suggests that social media use did not cause increased anxiety and depression of Chinese and International students during COVID-19. No significant difference was also found between the impact of social media use on anxiety and depression among the two categories of students. This study provides valuable insights into understanding the impact of social media use on anxiety and depression among students during the peak of COVID-19. Based on the findings of this study, stakeholders must continue to roll out online initiatives, such as mental health programs, online counselling and circulation of relevant COVID-19 related information on universities' websites, microblogs and other social media websites. These programs could help mitigate the harmful effects of social media among students in COVID-19.

Obesity has become a major health issue in recent decades, and has been documented to exert unfavourable effects on humans and animals and potentially affect the health of their offspring. However, the long-term effects of maternal obesity during the perinatal period on metabolic systems of the offspring have not been determined. Our group has long been focus on to explore epigenetic mechanisms underlying the inter- or trans-generational influence of maternal obesity/diabetes and identify critical molecules which are associated with metabolic programming under conditions of intrauterine and or postnatal obesogenic conditions. Here, we investigate metabolic effect of early activated hypothalamic endoplasmic reticulum (ER) stress in offspring exposed to maternal obesogenic environment and the potential mechanism underlying the metabolic abnormalities. Our study demonstrated that the uncoordinated interaction between the unfolded protein response and the heat shock response might be responsible for the malformed hypothalamic feeding circuit of the offspring exposure to maternal obesogenic conditions and were linked with deleterious metabolism in adulthood, especially when exposure to high-energy conditions.

This study aims to investigate the effects of stress-induced phosphoprotein 1 (STIP1) on spinal cord ischemia-reperfusion injury (SCII). SCII was induced by clamping the abdominal aorta for 1 h and reperfusion for 24 h in rats. Immunoblotting and immunohistochemical staining results showed that STIP1 rapidly increased and then decreased in the spinal cord of rats with SCII treatment. Lentivirus containing STIP1 coding sequence was intrathecally injected into rats to overexpress STIP1. Neurological function score, HE staining, immunofluorescent staining, and western blot results revealed that STIP1 overexpression alleviated SCII-induced motor dysfunction of hind limbs, neuronal loss and inflammation in the spinal cord, and inhibited activity of nuclear factor kappa B (NF-κB) signaling in rats. Moreover, STIP1 co-located with Iba-1, a marker of activated microglia. Mouse microglia BV2 underwent oxygen and glucose deprivation (OGD) for 6 h, and reperfusion for 24 h. STIP1 ameliorated OGD-induced inflammation and activation of NF-κB signaling in BV2 cells. In addition, STIP1 resulted in the decrease of heat shock protein family A member 8 (HSPA8), an increase of inhibitor of NF-κB (IκB)β levels, and IκBβ bound to HSPA8 in BV2 cells. We hypothesized that STIP1 elevated IκBβ levels by occupying HSPA8, and then deactivated NF-κB signaling. In summary, STIP1 alleviated ischemia-reperfusion induced neuronal injury and inflammation in the spinal cord of rats and mouse microglial cells by deactivating NF-κB signaling. These findings may provide novel insights for clinical diagnosis and treatment for spinal cord injury.

演讲主题：Key Molecular Alterations in Endothelial Cells in Human Glioblastoma Uncovered by Single-Cell RNA Sequencing

查看更多信息

Glioblastoma is the most aggressive type of brain tumor with poor therapeutic response and prognosis. Passage of systemically delivered pharmacological agents into the brain is largely blocked by the blood-brain-barrier (BBB), an organotypic specialization of brain endothelial cells (ECs). Tumor vessels in GBM are abnormal and generally more permeable, but the heterogeneity of BBB breakdown in different parts of the tumor vascular tree and in vessels surrounding the tumor is largely unknown. Here, through single-cell RNA sequencing (sc-RNAseq) of freshly isolated ECs from human glioblastoma and paired non-malignant tissues, we have constructed a molecular atlas of human brain ECs providing unprecedented molecular insight into the heterogeneity of the human BBB and its molecular alteration in glioblastoma. We identified 5 distinct EC phenotypes, resembling different phenotypes and associating with distinct anatomical location within the tumor. This unique resource will provide key information for designing rational therapeutic regimens and optimizing drug delivery.

Embolic agents with narrow size distribution and wide scale range are highly required in transarterial chemoembolization. In this study, a one-step electrospray technique has been developed for the preparation of nano-in-micron multifunctional embolic microspheres. Monodisperse calcium alginate (CaAlg) microspheres with a particle size range of 180 to 1000 μm were fabricated for the embolization. Nanoparticles, such as tantalum, BaSO₄ and Fe₃O₄, were incorporated into the microspheres to realize the medical image diagnoses. Doxorubicin hydrochloride was bonded to CaAlg microspheres to prepare drug-eluting beads for the chemotherapy. They were evaluated for the ability of chemotherapy by investigating the drug loading behavior, the encapsulation efficiency, the cytotoxicity, in vitro and in vivo release under different experimental conditions. The cell viability and hemocompatibility assays indicated the CaAlg microspheres possessed excellent biocompatibility. DSA and histological studies demonstrated the microspheres exhibited good embolization efficacy. In vivo assessment showed that the microspheres had long-term X-ray / NMR imaging capability. They could not only display their own location and distribution precisely in real time during the operation of transcatheter arterial embolization, but also carry out noninvasive examination after operations. These results suggest that the “3-in-1” microspheres combined with embolization, chemotherapy and image diagnoses can be envisioned in the treatment of advanced hepatocellular carcinoma.

2021年11月26-28日

By the end of October 2021, COVID-19 had spread to over 230 countries, with more than 240 million confirmed cases and 5.0 million deaths. To control infection spread with the least disruption to economic and societal activities, it is crucial to implement the various interventions effectively. In this study, we developed an agent-based SEIR model, using real demographic, geographic, and human-behavior data from Hong Kong, to analyze the efficiency of various intervention strategies in preventing infection by the SARS-CoV-2 virus. Close contact route including short-range airborne is considered as the main transmission routes for COVID-19 spread. Contact tracing is not that useful if all other interventions have been fully deployed. The number of infected individuals could be halved if people reduced their close contact rate by 25%. For reducing transmission, students should be prioritized for vaccination rather than retired older people and preschool aged children. Home isolation, and taking the nucleic acid test (NAT) as soon as possible after symptom onset, are much more effective interventions than wearing masks in public places. Temperature screening in public places only disrupted the infection spread by a small amount when other interventions have been fully implemented. Our results may be useful for other highly populated cities, when choosing their intervention strategies to prevent outbreaks of COVID-19 and similar diseases.

2021年5月29-31日

The microbiological, biochemical, and physicochemical changes of ready-to-eat shrimps (Penaeus vannamei) with high water content, subjected to nisin treatment in combination of hurdle technology, were investigated. The ready-to-eat shrimps were processed by boiling, drying, treatment with nisin solution, seasoning, and roasting, followed by vacuum packaging, sterilization, and storage at room temperature (25 °C). The results showed that the samples treated with nisin in combination with other hurdles resulted in a significant decrease in bacterial counts (Bacillus cereus and native microflora) compared to the control samples. Additionally, the nisin-treated samples possessed better biochemical and physicochemical properties, as well as better sensory patterns. According to the safety guidelines for roasted shrimp (SC/T 3305-2003), the shelf life of ready-to-eat shrimp with 48–53 % moisture content was extended by nisin application at concentrations of 60 and 100 mg/kg of nisin; specifically, ready-to-eat shrimp maintained good quality from 4–6 days up to 6–12 and 8–14 days corresponding to 60 and 100 mg/kg of nisin treatments, respectively. Nisin treatment combined with hurdle technology in the production of ready-to-eat shrimp provides a highly valued product in China.

演讲主题：Comprehensible Explanations of Determination Methods of Three Basic System Properties

查看更多信息

In the course of learning Signals and Systems, it is one of the emphases and difficulties to determine the basic system properties, such as linearity, time-invariance and causality. In teaching, it is found that students often only know the written expression of the determination methods, but do not understand the core of the determination methods. So they feel difficult to use. In order to help students to understand, this paper focuses on giving popular and common explanations to the traditional determination methods of the above three basic system properties, rather than sticking to the rigor of the theory. As for linearity determination, from the embodiment of additivity and homogeneity, the input signals are constructed; the discrimination of time invariance is considered from two aspects: time delay and the transformation of signals by systems; it is more convenience for judgment of causality to obtain the time relationship of output and input from some special moments. By means of the comprehensible explanations of the determination methods in this paper, students can easily understand and master the traditional determination methods of three basic system properties. More importantly, they can apply it to solve the determination problems of linearity, time invariance and causality of systems.

2021年5月27-29日

This article tries to address the puzzle of a small share of China’s outward direct investment (CODI) in ASEAN by investigating the determinants of CODI in ASEAN over the period 1995 to 2019. Evidence presented in this article indicates that the small CODI cannot be fully appreciated without understanding differences between CODI in ASEAN and that in EU, the latter attracting CODI at full speed. Empirical results suggest that the CODI in ASEAN was primarily motivated by resource and market access, and that in EU was technical and strategic assets oriented. The main purpose of Chinese investors to invest abroad is not to use their existing ownership advantages expanding overseas production, but to compensate their disadvantage and improve competitiveness to strengthen the domestic production. The small CODI in ASEAN thus is a result of China investors' strong interest in gaining raw materials, skilled labor, sale channels and potential market for its export rather than benefiting from cheap labor and ASEAN's export and employment-promotion FDI regime, poor infrastructure, containment attitude for China investors, along with the political instabilities in ASEAN.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has led to more than fourteen million confirmed cases, with over three million deaths globally, as of April 20, 2021. To date, almost all diagnostic testing for the virus occurs in centralized laboratories, and involves expensive laboratory equipment, lengthy assays, and trained laboratory technicians. Developing rapid, simple, sensitive and specific and cheap to mass produce diagnostic assays remains an urgent need. We have developed a novel technique of fluorescent bioprobe based diagnosis for SARS-CoV-2 virion. The features of this method are rapid, simple, sensitive and suitably applied for point-of-care (POC) and high-throughput tests. The development of test kid by this novel diagnostic platform may provide fruitful diagnosis for SARS-CoV-2 based on its accurate, specific and easy to run, producing results in a short time, and cheap to mass produce.

演讲主题：Chronic HIV Infection Primes Hyper Inflammatory Response to Subsequent Infections in AIDS Patients by Disturbing Immunometabolic Homeostasis

查看更多信息

Despite the successful control of HIV replication by antiretroviral therapy, the consequent hyper-inflammatory sepsis upon subsequent infection becomes a leading cause of AIDS-associated death. It has been attributed to the hyper inflammatory priming by persistent immune activation and GLUT1-dependent hyper-glycolytic activity, however, the underlying knowledge is still incomplete. We have recently revealed that the imbalance of pro- and anti-inflammatory signaling is responsible for the immunometabolic modifications of AIDS patients. Upon activation of TLR4 signaling, AIDS immune cells expressed significantly higher pro-inflammatory cytokines and GLUT1-dependent glycolysis than healthy immune cells did, which was contrary to the repressed expression of the anti-inflammatory genes. Stimulating anti-inflammatory signaling reversed inflammatory imbalance by restricting nuclear translocation of pro-inflammatory gene transactivator but prompting nuclear translocation of pro-inflammatory gene repressors. Thus, restoring homeostasis of pro- and anti-inflammatory signaling of AIDS immune cells by activation of anti-inflammatory signaling promises prevention and effective therapy of AIDS-related sepsis.

His previous works had produced a panel of immunotoxins for molecularly targeted therapies for glioblastoma and acute leukemia, and demonstrated APPL serves as a molecular link between extro- and intro-cellular signalings.

演讲主题：Astragaloside III Enhance the Tumor Response of NK Cells by Elevating NKG2D and IFN-γ

查看更多信息

Natural killer (NK) cells play an irreplaceable role in the development of colon cancer, in which antitumor function of NK cells was impaired. Astragaloside III is a natural compound from Astragalus that has been shown to have immunomodulatory effects in various systems. However, few studies have evaluated the antitumor effects of Astragaloside III through stimulating systemic immunity and regulating NK cells. In this study, flow cytometry, immunohistochemical analysis, and immunofunctional assays were performed to elucidate the functions of Astragaloside III in restoring antitumor function of NK cells. We demonstrated that Astragaloside III significantly elevated the expression of natural killer group 2D (NKG2D), Fas, and interferon-γ (IFN-γ) production in NK cells, leading to increased tumor-killing ability. Experiments in cell co-culture assays and CT26-bearing mice model further confirmed that Astragaloside III could effectively impede tumor growth by increasing infiltration of NK cells into tumor and upregulating the antitumor response of NK cells. We further revealed that Astragaloside III increased IFN-γ secretion of NK cells by enhancing the expression of transcription factor T-bet. In conclusion, the effective anti-tumor function of Astragaloside III was achieved through up-regulation of the immune response of NK cells and elevation of NKG2D, Fas, and IFN-γ production.

Exploring the complicated relationships underlying the clinical information is essential for the diagnosis and treatment of various diseases. Based on the real-world electronic medical records (EMRs) of the Coronavirus Disease 2019 (COVID-19) and Chronic Insomnia, an AI-based model of diagnosis and treatment is proposed for the clinical knowledge discovery. This model constructs the heterogeneous information network to exploit the complex relationships among the syndromes, symptoms, and medicines. Then, it generates the numerical symptom (medicine) embeddings and divides them into seven communities (syndromes) using the combination of the Skip-Gram model and Spectral Clustering (SC) algorithm. It identifies the key factors in symptom and medicine networks using six evaluation metrics of node centrality. The experimental results indicate that the proposed model is capable of discovering the critical symptoms and symptom distribution for diagnosis; the key medicines and medicine combinations for treatment. Furthermore, this model can provide tremendously valuable guidance and help physicians to combat the COVID-19 or other diseases.

2021第五届能源，环境与自然资源国际会议

2021年5月27-29日

Conventional ionic conductivity has been developed by ionic conducting materials for the electrolyte. Typically, solid oxide fuel cell (SOFC), yttrium stabilized zirconia (YSZ) electrolyte, which needs high operational temperature above 700 °C to reach required ionic conductivity. High temperature requirements cause a delay of the SOFC commercialization. Metal oxide Semiconductor (MOS)-based materials possess basically intrinsic electronic conduction and mixed by extrinsic ionic conduction, they have been explored and developed as new functional material family with superionic conduction to replace the conventional electrolytes for new generation fuel cell technology and application. The band structure, p-n junction and build-in-field have been discovered to facilitate fast ionic transport. Tuning semiconductors and heterostructures to ionic conductors is a very effective approach to develop effective electro-catalysts and superionic conductivities for next generation fuel cells and novel energy devices. For example, fuel cells built on anode, electrolyte and cathode three components can now be constructed by semiconductor-ionic one component to realize more efficiently the fuel cell hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) through band structure and alignment without using the electrolyte separator. Numerous amounts of semiconductor-ionic materials have been explored and novel MOS fuel cell technologies have been demonstrated. Some examples are bulk hetero p-n junction and Schottky junction for single layer fuel cells, designed by energy bands and alignments. New disciplines of Semiconductor-Ionics and Semiconductor Electrochemistry have been establishing not only for energy conversion, e.g. fuel cells, but also for energy storage devices like batteries.

Dr. Bin Zhu, Professor has been studying ceramic fuel cell, materials, technology and science including superionic conductor and electrocatalysis, semiconductor-ionic materials and single layer fuel cell, electro-catalyst reaction, charge separation and transfer and surficial and interfacial ionic transport mechanisms for more than 30 years.

演讲主题：Advanced Control of Solvent-based Carbon Capture System for Wide Range Flexible Operation

查看更多信息

Solvent-based carbon dioxide capture technology is currently the most promising technology for coal-fired power plant flue gas carbon capture. Because coal-fired power plants are widely involved in peak regulation and the chemical solvent regeneration requires to consume huge amount of heat, it is of great significance to conduct overall scheduling and control research on the integrated coal-fired power plant-carbon capture process to achieve flexible operation of the system. This study develops a high-precision simulation platform for Supercritical coal-fired power plant-carbon capture system. An overall optimal scheduling method for power plant carbon capture system in the context of renewable energy penetration is proposed, and the role of power plant-carbon capture system in future low carbon energy mix is studied. A novel control scheme for the power plant-carbon capture is proposed based on the model predictive control (MPC) to track the scheduling results, in which the re-boiler steam flowrate is incorporated in the boiler-turbine coordinated control system to assist the regulation of power output and the lean solvent flow is used to control CO2 capture rate in the carbon capture system. By making full use of the interactions and time scale difference between the supercritical coal-fired power plant and the solvent-based post-combustion carbon capture system, the proposed approach can effectively improve the load response speed of the power plant, making it have a stronger peak-shaving capacity of the power grid with limited impact on the operation of the carbon capture system.

演讲主题：Developing a Powerful Assessment Tool to Quantify Climate Change Impacts and Future Risk in High Spatial Resolution for the Southeastern of China

The impacts of climate change on the south-eastern of China have been witnessed in recent years, but the previous studies are too coarse in spatial resolution resulting. These studies cannot be used for local infrastructure and natural disaster prevention planning and engineering design. Further, the lack of appropriate assessment tools to quantify the future risk is a major obstacle for city planners and engineers. To overcome these difficulties and challenges we developed a powerful assessment tool based on high-resolution climate and hydrology models to quantify the future risk caused by the climate impacts. The tool can quantify rainfall characteristics, extreme weather events, flood risk from 4-12 square kilometers up to 2060 on a spatial-temporal scale. The tool was used in Zhuhai natural disaster prevention master plan as an excellent application example.

2021第五届土木与环境工程国际会议

2021年5月27-29日

With developments in electric power, energy, and transportation industries in china, the number of steel pipelines is now increasing rapidly as energy transportation through pipelines has unique advantages. Since oil & gas within the pipelines are flammable and explosive, pipeline failures would cause many casualties and huge economic losses, also resulting in serious pollution to the environment. Therefore, pipeline damage inspection is of top priority to insure the safety of pipelines. However, the existed external inspection technologies for buried pipeline damage demand excavation of the pipeline which makes these technologies of high cost and low efficiency. Meanwhile, excavation of the pipeline may cause new damages to the pipeline. In order to solve this both scientific and engineering challenge, a noncontact detection technology based on weak magnetic field was proposed. This talk will present a systematic report on the research of this technology which mainly includes: 1) the detection mechanism; 2) design on a multi-space full tensor magnetic gradient detection array probe; 3) coupling law of pipeline damage and magnetic anomalies along with its decoupling method; 4) pipeline damage identification and positioning algorithm; 5) engineering applications.
