Time dependent density functional theory(TDDFT)is a useful tool to calculate molecular properties with reasonable computational costs comparing to wave function based ab initio approaches.A linear sca
Previously,we developed a Gaussian charge distribution model [1](GM)containing only spherical Gaussian functions to partition the molecular electron density into overlapping spherical atomic domains.H
Ideally,quantum mechanical/molecular mechanical methods are capable of providing reliable predictions of molecular properties in condensed phase.However,the applications of QM/MM methods in free energ
For graphene growth and application,the subtle interaction between transi tion metal and graphene is widely investigated experimentally and theoretically.
Under mild static compression(15 GPa),graphite preferentially turns into hexagonal diamond,not cubic diamond,the selectivity of which is against thermodynamics.Here we,via novel potential energy surfa
Lithium–sulfur(Li–S)battery is considered as an ideal next-generation energy storage device as its high energy capacity.However,several issues have resisted its practical applications,like the dissolu
Protein lysine methyltransferases(PKMTs)catalyze the methylation of lysine residues on the tails of histone proteins.In contrast to many other PKMTs for which unmodified lysine is the methylation targ
Density functional theory calculations have been performed to study the detailed mechanism of Ni -catalyzed [3+2] cycloaddition of 2-trifluoromethyl-1-alkenes with alkynes1 (eq.1) via cleavage of two
Some synthetic supramolecular containers have been found to act as enzymes to catalyze chemical reactions [1-3].Such catalysis can be termed supramolecular catalysis,which originally utilizes non-cova
