Computational study of the NO, SO2, and NH3 adsorptions on fragments of 3N-graphene and Al/3N grapheneJournal of Molecular Modeling - Tập 24 - Trang 1-10 - 2018
Yao-Dong Song, Liang Wang, Qian-Ting Wang
The adsorption properties of common gas molecules (NO, NH3, and SO2) on the surface of 3N-graphene and Al/3N graphene fragments are investigated using density functional theory. The adsorption energies have been calculated for the most stable configurations of the molecules on the surface of 3N-graphene and Al/3N graphene fragments. The adsorption energies of Al/3N graphene-gas systems are −220.5 ...... hiện toàn bộ
Interactions between Al12X (X = Al, C, N and P) nanoparticles and DNA nucleobases/base pairs: implications for nanotoxicityJournal of Molecular Modeling - Tập 18 - Trang 559-568 - 2011

The interactions between neutral Al12X(I
h
) (X = Al, C, N and P) nanoparticles and DNA nucleobases, namely adenine (A), thymine (T), guanine (G) and cytosine (C), as well as the Watson−Crick base pairs (BPs) AT and GC, were investigated by means of density functional theory computations. The Al12X clusters can tightly bind to DNA bases and BPs to...... hiện toàn bộ
Investigation of the structural dynamics of a knotted protein and its unknotted analog using molecular dynamicsJournal of Molecular Modeling - Tập 28 - Trang 1-12 - 2022
José Cícero Alves Silva, Elton José Ferreira Chaves, Gabriel Aires Urquiza de Carvalho, Gerd Bruno Rocha
The role of knots in proteins remains elusive. Some studies suggest an impact on stability; the difficulty in comparing systems to assess this effect, however, has been a significant challenge. In this study, we produced and analyzed molecular dynamic trajectories considering three different temperatures of two variants of ornithine transcarbamylase (OTC), only one of which has a 31 knot, in order...... hiện toàn bộ
Study of the pyrolysis of coals of different rank using the ReaxFF reactive force fieldJournal of Molecular Modeling - Tập 25 - Trang 1-17 - 2019
Longzhen Guo, Zhijun Zhou, Liping Chen, Shiquan Shan, Zhihua Wang
Based on the general coal model, the processes of pyrolysis of coals of different rank were studied by molecular dynamics simulations with the ReaxFF reactive force field. Simulations were performed over wide temperature ranges both for heating from 300 K to 3000 K and a constant temperature range from 2000 K to 3500 K. The pyrolysis of coals of different coal rank under different heating conditio...... hiện toàn bộ
High cell voltage and storage capacity of graphyne as the anode of K-ion batteries: computational studiesJournal of Molecular Modeling - Tập 26 - Trang 1-7 - 2020
Xiuxiu Zhang, Hamid Asadi
Li-ion batteries have many advantages, but these batteries suffer from safety problems, short lifetime, and a high cost. Nontoxicity, wide availability, and low cost of potassium offer the K-ion batteries (KIB) as a replacement to the Li-ion batteries. The B3LYP-gCP-D3 approach of density functional theory is applied to examine the probable application of graphyne in the anode of KIBs. It is found...... hiện toàn bộ
Interference of H-bonding and substituent effects in nitro- and hydroxy-substituted salicylaldehydesJournal of Molecular Modeling - Tập 18 - Trang 127-135 - 2011
Aneta Jezierska-Mazzarello, Halina Szatyłowicz, Tadeusz Marek Krygowski
Two intramolecular interactions, i.e., (1) hydrogen bond and (2) substituent effect, were analyzed and compared. For this purpose, the geometry of 4- and 5-X-substituted salicylaldehyde derivatives (X = NO2, H or OH) was optimized by means of B3LYP/6-311 + G(d,p) and MP2/aug-cc-pVDZ methods. The results obtained allowed us to show that substituents (NO2 or OH) in the para or meta position with res...... hiện toàn bộ
