The Singular Energy Points Changes the Global Structural Modes

Abstract

After we describe the world by the energy function, we will see that the great changes in the appearance of the earth, since the Carboniferous period, are caused by the appearance of the upper mantle energy singularity below the continents, which promote the accretion of the continents and the deformation of the lithosphere, and change the global tectonic pattern. Earth's mantle energy singularities include continental fault conjunctions, continental syntaxis, asthenosphere diapirs, and Great Rifts. The expansion and divergence of energy singularities, and their evolution from continental splitting, mid-ocean ridge expansion, continental drift to continental collision and subduction，are discussed based on three-dimensional imaging of the upper mantle beneath the South African fault trijunction, the Tibetan Plateau syntaxis, the Baiyunebo asthenosphere diapir, and the Great Rift Valley.

Nature-Chemistry Relationship Involving Oxygenated Organic Compounds

Abstract

Oxygenated organic compounds (OOC), represented by alcohols, carbonyls, and their derivatives, are ubiquitous in both synthetic realm and natural molecules. Therefore, the study of OOC serves as an ideal platform to further investigate the tie between Chemistry and Nature. During the past 5 years, we have revealed various toxicological effects of -OH functional group both in vivo and in vitro using polyethylene as the platform. In addition, we have developed a series of more sustainable synthetic methodologies for OOCs that minimize the environmental impact on nature and the society. The interdisciplinary study was aiming to further advance the development of green chemistry and strengthen the tie between the environment and the society.
