The activity of indenylidene derivatives in olefin metathesis catalysts

open access: yesBeilstein Journal of Organic Chemistry, 2018
The first turnover event of an olefin metathesis reaction using a new family of homogenous Ru-based catalysts bearing modified indenylidene ligands has been investigated, using methoxyethylene as a substrate.

Computational molecular characterization of the flavonoid rutin

open access: yesChemistry Central Journal, 2010
In this work, we make use of a model chemistry within Density Functional Theory (DFT) recently presented, which is called M05-2X, to calculate the molecular structure of the flavonoid Rutin, as well as to predict the infrared (IR) and ultraviolet (UV-Vis)

Monte Carlo and DFT calculations on the corrosion inhibition efficiency of some benzimide molecules

open access: yesMongolian Journal of Chemistry, 2023
Calculations using density functional theory (DFT) and Monte Carlo methods were performed on 2-methylbenzimidazole, 2-mercaptobenzimidazole, 2-aminobenzimidazole, benzotriazole, and benzimidazole to determine their corrosion inhibition efficiency.

Dynamical variational principles for strongly correlated electron systems

open access: yes, 2005
The self-energy-functional approach (SFA) is discussed in the context of different variational principles for strongly correlated electron systems. Formal analogies between static and dynamical variational approaches, different types of approximation ...

A multideterminant assessment of mean field methods for the description of electron transfer in the weak coupling regime

open access: yes, 2009
Multideterminant calculations have been performed on model systems to emphasize the role of many-body effects in the general description of charge quantization experiments. We show numerically and derive analytically that a closed-shell ansatz, the usual

Recent developments in classical density functional theory: Internal energy functional and diagrammatic structure of fundamental measure theory [PDF]

open access: yes, 2012
An overview of several recent developments in density functional theory for classical inhomogeneous liquids is given. We show how Levy's constrained search method can be used to derive the variational principle that underlies density functional theory ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

L-cysteine sequestering methyl glyoxal prevents protein glycation: a combined in vitro and in silico evaluation

open access: yesCurrent Issues in Pharmacy and Medical Sciences
Reactive carbonyl species such as methylglyoxal (MGO) act as potent glycating agents that are implicated in several oxidative stress-induced diseases, including, but not limited to, cancer, diabetes and neurodegenerative diseases such as Alzheimer’s and ...

A new approach to local hardness

open access: yes, 2011
The applicability of the local hardness as defined by the derivative of the chemical potential with respect to the electron density is undermined by an essential ambiguity arising from this definition. Further, the local quantity defined in this way does
