Ultra-high permeable phenine nanotube membranes for water desalination [PDF]
Nanopore desalination technology hinges on high water-permeable membranes which, at the same time, block ions efficiently. In this study, we consider a recently synthesized [Science 363, 151-155 (2019)] phenine nanotube (PNT) for water desalination ...

Benchmarking GW against exact diagonalization for semi-empirical models [PDF]
We calculate groundstate total energies and single-particle excitation energies of seven pi conjugated molecules described with the semi-empirical Pariser-Parr-Pople (PPP) model using self-consistent many-body perturbation theory at the GW level and ...

Influence of van der Waals forces on the adsorption structure of benzene on silicon studied using density functional theory [PDF]
Two different adsorption configurations of benzene on the Si(001)-(2 x 1) surface, the tight-bridge and butterfly structures, were studied using density functional theory.

The Properties of Pure Liquids [PDF]
By a semiempirical approach, a method is found to calculate the specific heat of a normal pure liquid at constant pressure form the specific heat of the gaseous state at the same temperature.
