On the many‐body nature of intramolecular forces in FFLUX and its implications [PDF]

open access: yesJournal of Computational Chemistry, 2020
AbstractFFLUX is a biomolecular force field under construction, based on Quantum Chemical Topology (QCT) and machine learning (kriging), with a minimalistic and physically motivated design. A detailed analysis of the forces within the kriging models as treated in FFLUX is presented, taking as a test example a liquid water model.

Intramolecular Force Field of some Tetrahedral Molecules and Ions [PDF]

open access: yesZeitschrift für Naturforschung A, 1972
Abstract The orbital valence force field (OVFF), and the Urey-Bradley force field (UBFF) have been employed to calculate the force constants for six molecules and ions (AlCl4 -, AlBr4 -, AlI4 -, Til4 - , Os16O4 , and Os18O4).

Antibacterial Studying of Silver Nanoparticles Synthesized by Chemical Reduction Method Using Different Stabilized Concentrations [PDF]

open access: yesJournal of Applied Sciences and Nanotechnology, 2022
Silver nanoparticles were prepared by the chemical reduction method. Silver nitrate was taken as a metal precursor and sodium borohydride as a reducing agent with polyvinyl alcohol (PVA) stabilizers of different concentrations, polyvinylpyrrolidone (PVP).

Control of oxidation and spin state in a single-molecule junction [PDF]

open access: yes, 2018
The oxidation and spin state of a metal–organic molecule determine its chemical reactivity and magnetic properties. Here, we demonstrate the reversible control of the oxidation and spin state in a single Fe porphyrin molecule in the force field of the ...

Molecular Structure and Modeling of Water-Air and Ice-Air Interfaces Monitored by Sum-Frequency Generation. [PDF]

open access: yes, 2020
From a glass of water to glaciers in Antarctica, water-air and ice-air interfaces are abundant on Earth. Molecular-level structure and dynamics at these interfaces are key for understanding many chemical/physical/atmospheric processes including the ...
