Orbital hybridization describes the mixing of orbitals to form a hybrid that is suited for the electron pairing in accordance with the valence bond theory. A molecule with 4 groups (one lone pair=one group) attached to the central atom is sp3 hybridized; 3 groups = sp2 hybridized; 2 groups...
Adoption of no-till management on croplands has become a controversial approach for storing carbon in soil due to conflicting findings. Yet, no-till is still promoted as a management practice to stabilize the global climate system from additional change due to anthropogenic greenhouse gas emissions,...
First-principles study of the electronic and optical properties in rhombohedral LaAlO3 In this paper, the electronic structure, chemical bonding, and optical properties of rhombohedralLaAlO3are investigated by using the full potential lineari... L Xin,B Wang - 《Journal of Applied Physics》 被引量...
Regulation of complement activation in the host cells is mediated primarily by the regulators of complement activation (RCA) family proteins that are formed by tandemly repeating complement control protein (CCP) domains. Functional annotation of these pr
Hemicelluloses–the earth's second most abundant natural polymer after cellulose–constitute 10–50% of the biomass4,5, interlinking the cellulose chains inside the plant cell walls through hydrogen bonding6 and being covalently bonded to the lignin chains7. Cell wall deconstruction8 and hemicellu-...
However, this repulsion is presumably tamed upon successive protonation, so the side chain carboxylates on the pendant, flexible side chains may ap- proach each other and even water-molecule-mediated hydrogen-bonding networks might be suspected at some stages of protonation. The "crowding" of COOH...
