This gives single-bond covalent radii using specific group valencies and oxidation numbers.Image showing periodicity of the chemical elements for covalent radii (molecular single bond) in a bar chart.UnitspmNotes This is a self-consistent system of additive covalent radii, R(AB)=r(A) + r(B)...
Solanki et al. [195] calculated the cohesive energy of symmetric grain boundaries with different inclination angles ofα-Fe. They found that only part of the cohesive energy of the grain boundary structure was reduced, while the other part of the cohesive energy of the grain boundary structure...
mirror planes can be distinguished asσh(perpendicular to main axis),σv(containing the main axis) orσd(containing the main axis and bisecting bond angles), thoughσvandσdcan be grouped together. • rotations and improper axes can generate several operations (Cnm, Snm) while only one ope...

4.2.3. Docking simulations The core structures of compounds 31 and 37 were constructed using standard bond lengths and bond angles of the MOE fragment library. Geometry optimizations were accomplished with the MMFF94X force field available inside MOE. Docking simulations were carried out starting ...
Over half of mitochondrial proteins are imported from the cytosol via the pre-sequence pathway, controlled by the TOM complex in the outer membrane and the TIM23 complex in the inner membrane. The mechanisms through which proteins are translocated via th
