The charge distribution in the water molecule has been analyzed using a broad variety of basis sets, four different quantum mechanical methods (Hartree–Fock, Becke3LYP, MP2, and QCISD), and six population analysis methods (Mulliken, NPA, AIM, CHELPG, Merz–Kollman, and Resp). The influence...

Serine-based β-lactamases of Class A, C and D all rely on a key water molecule to hydrolyze and inactivate β-lactam antibiotics. This process involves two conserved catalytic steps. In the first acylation step, the β-lactam antibiotic forms an acyl-enzyme intermediate (ES*) with the catal...
Reverse osmosis filterscan trap any molecule bigger than water. They are typically more effective than carbon filters since they can remove fluoride. A reverse osmosis filter is my personal recommendation. Then there is the promising 2024 research that shows you can boil water to remove the majorit...
The method is based on the evolution of a coherent state representation of the supermolecule wavefunction within the time-dependent variational principle. We calculate differential and total cross sections for the scattering of the projectile, charge transfer, and fragmentation of the system products. ...
①hydration and hydration number The number of water molecules in a cluster formed by a sugar molecule is described by its hydration number. Hydration 就是这个作用的名字。hydrated number越大,说明糖与水的作用效果越好。 ②模型解析 AB是两个isomer。 右图的水堆积方式其实是水最“习惯”的堆积方式,而...
The V atom adsorbing the water molecule is defined as V-1, the V-2 corresponds to the one with the largest positive partial charge, while V-3 is at the minima. c The O-binding energies (EO–binding, green dots) of O to Vn+, and the zero-point-vibration corrected total energies of...
The hydrogen bond is modeled classically with Coulomb interactions, and shows significant improvement in predicting cluster behavior by adding directional character via an overlap between a lone pair orbital on oxygen and the hydrogen of an adjacent molecule. An implicit bond polarization is present due...
