1. On the basis of Thomson’s model of an atom, explain how the atom is neutral as a whole. Ans:As per Thomson’s model of an atom, the number of electrons and the number of protons are equal in an atom. Electrons are positively charged and protons are negatively charged, hence the...

where Gsys and Gsub were the energy of the system and substrate, EGa was the energy of the Ga atom in its bulk structure, N1/N2 was the number of Ga/Te atoms, A was the area of the metal surface in the supercell calculation. Characterizations OM images were performed by Olympus DX51...
In the above-mentioned hydrogenation reaction, the hydrogen atom is transferred to the same side (cis) of the alkyne, resulting in cis alkenes by introducing syn (addition of two substituents on the same side of a double or triple bond resulting in a decrease in bond number). All hydrogen ...
] that belong to Class I structures. Regardless of the level of overall sequence identity, these enzymes share a common conserved S-adenosyl-L-methionine (SAM) binding domain with a core α/ß Rossman fold [18] and a unique α-helical cap that forms the top of the active site cavity....
QSAR, first established by Corwin Hansch (Hansch et al., 1962), was a natural extension of physical chemistry into the field of virtual drug screening. After more than 50 years of development with interdisciplinary breakthroughs and community promotion, QSAR has transformed from simple regression an...

Versions Notes Abstract A tight binding supercell approach is used for the calculation of the electronic structure of the (111) LaAlO33/SrTiO33 interface. The confinement potential at the interface is evaluated solving a discrete Poisson equation by means of an iterative method. In addition to th...
Versions Notes Abstract With the aim to find the best simulation routine to accurately predict the ground−state structures and properties of iron oxides (hematite, magnetite, and wustite) using density functional theory (DFT) with Hubbard-U correction, a significant amount of DFT calculations were...
How is this diagram of the structure of diamond correct? see this diagram of the structure of diamond given in my textbook- I have read in my textbook that each carbon atom in a Diamond crystal is attached to four other carbon atoms by strong covalent bonds.But, in the diagram above I ...
