Comparing Homodimer and Homotrimer Noncovalent Complexes Involving Coinage Metals: A Theoretical Perspective. [PDF]

open access: yesChemphyschem
In this study, the ability of M2 clusters (M = Cu, Ag, and Au) to form noncovalent homodimers/homotrimers has been evaluated at the RI‐PBE0‐D4/def2‐TZVPD level of theory. The results have been complemented with QTAIM, NCIplot, and EDA analyses, which helped to shed light on the physical nature of these unconventional noncovalent contacts. In this study,

On the Dynamics of Noncovalent Interactions Modulating Passive Diffusion of Cisplatin Across a Human Breast Cancer Cell Membrane: An amIGM + GLED View [PDF]

open access: yesChempluschem
A combined amIGM/GLED framework based on classical MD simulations at finite‐temperature conditions is proposed to investigate the passive permeation of cisplatin anticancer drug across a breast cancer model membrane. Dynamic real‐space analysis of nanosolvation reveals how noncovalent interaction patterns evolve from bulk water to the membrane free ...

The two-component quantum theory of atoms in molecules (TC-QTAIM): tensor formulation and its implications [PDF]

open access: yesTheoretical Chemistry Accounts, 2013
In this contribution, the tensor formulation of the two-component quantum theory of atoms in molecules is addressed in detail. The subsystem hypervirial and the regional atomic theorems are presented in their local forms enabling one to introduce the tensor formulation easily.
