Molecular Dynamics of CH4/N2 Mixtures on a Flexible Graphene Layer: Adsorption and Selectivity Case Study

open access: yesFrontiers in Chemistry, 2019
We theoretically investigate graphene layers, proposing them as membranes of subnanometer size suitable for CH4/N2 separation and gas uptake. The observed potential energy surfaces, representing the intermolecular interactions within the CH4/N2 gaseous ...

NMR-Based Configurational Assignments of Natural Products: Gibbs Sampling and Bayesian Inference Using Floating Chirality Distance Geometry Calculations

open access: yesMarine Drugs, 2021
Floating chirality restrained distance geometry (fc-rDG) calculations are used to directly evolve structures from NMR data such as NOE-derived intramolecular distances or anisotropic residual dipolar couplings (RDCs).

Vibrational Assignments and Intramolecular Force Field of Trimethylaluminum [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1965
Abstract A vacuum infrared cell for reactive or intermediate species has been devised by the use of polyethylene sheets as optical windows. The infrared spectra in the 4000–3100cm−1, 2500–1500 cm−1, 1250–750 cm−1 and 700–65 cm−1 regions can be measured with this liquid cell.

Microscopic mechanisms of thermal and driven diffusion of non rigid molecules on surfaces [PDF]

open access: yes, 2002
The motion of molecules on solid surfaces is of interest for technological applications such as catalysis and lubrication, but it is also a theoretical challenge at a more fundamental level.

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.

Configurational temperature control for atomic and molecular systems [PDF]

open access: yes, 1994
A new configurational temperature thermostat suitable for molecules with holonomic constraints is derived. This thermostat has a simple set of motion equations, can generate the canonical ensemble in both position and momentum space, acts homogeneously ...

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).
