Low temperature fluorescence spectra of atropisomeric perylene dyes [PDF]

open access: yes, 1988
The site selection spectra of highly photostable perylene fluorescent dyes at 4.2 K in a glassy matrix of three different organic solvents (ethanol, methyl tetrahydrofuran, n-butyl acetate) are presented. The spectra ofthe two isomers are identical for a

Solvent Effects on the Menshutkin Reaction [PDF]

open access: yesarXiv, 2021
The Menshutkin reaction is a methyl transfer reaction relevant in fields ranging from biochemistry to chemical synthesis. In the present work, energetics and solvent distributions for NH$_{3}$+MeCl and Pyr+MeBr reactions were investigated in the gas-phase, in water, methanol, acetonitrile, benzene, and in cyclohexane by means of reactive molecular ...

A Smooth Interface Method for Simulating Liquid Crystal Colloid Dispersions

open access: yes, 2003
A new method is presented for mesoscopic simulations of particle dispersions in liquid crystal solvents. It allows efficient first-principle simulations of the dispersions involving many particles with many-body interactions mediated by the solvents ...

Implicit Solvation Using the Superposition Approximation (IS-SPA): Extension to Polar Solutes in Chloroform [PDF]

open access: yes, 2020
Efficient, accurate, and adaptable implicit solvent models remain a significant challenge in the field of molecular simulation. A recent implicit solvent model, IS-SPA, based on approximating the mean solvent force using the superposition approximation, provides a platform to achieve these goals.

Gas phase homolytic bond dissociation enthalpies of common laboratory solvents: A G4 theoretical study [PDF]

open access: yes, 2010
Gas phase standard state (298.15 K, 1 atm) calculations were conducted at the Gaussian-4 (G4) composite method level of theory to estimate the bond dissociation enthalpies (BDEs) of various common laboratory solvents.

Dendritic cells steering antigen and leukocyte traffic in lymph nodes

open access: yesFEBS Letters, EarlyView.
Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

Transport of particles through RO membrane in steady state condition [PDF]

open access: yesarXiv, 2023
Reverse Osmosis(RO) membranes are widespread nowadays for separating the solvent from a solution. RO membranes are made of polymer matrix. Experiments show changes in relative interaction of solvent and solute with RO membrane matrix lead to changes in solvent permeation, solute rejection and fouling.
