PROPERTIES OF THE TERT-BUTYL HALIDE SOLVOLYSIS TRANSITION STATES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 25 gennaio 2021 We have obtained properties (or descriptors) of the transition states in the solvolysis of tert-butyl chloride, bromide and iodide. We show that all three transition states, in both protic and in aprotic solvents, are highly dipolar and are strong hydrogen bond......

DIFFUSION OF THE CARBON DIOXIDE–ETHANOL MIXTURE IN THE EXTENDED CRITICAL REGION

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 25 gennaio 2021 The effect of traces of ethanol in supercritical carbon dioxide on the mixture’s thermodynamic properties is studied by molecular simulations and Taylor dispersion measurements. This mixture is investigated along the isobar p = 10 MPa in the temperature range between T......

CONFORMATIONAL TRANSITIONS OF ADSORPTION-RESPONSIVE SINGLE DIBLOCK COPOLYMERS IN HOMOPOLYMER BRUSHES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), sab 23 gennaio 2021 Using self-consistent field calculations, we examine the effect of brush polydispersity on conformational transitions of single adsorption-active diblock copolymer chains embedded in inert polydisperse brushes. To represent the polydispersity, we adopt the continuous Schulz–Zimm chain length distributions, and three typical distributions......

RHEOLOGY FINDS DISTINCT GLASS AND JAMMING TRANSITIONS IN EMULSIONS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 21 gennaio 2021 We study the rheology of monodisperse and bidisperse emulsions with various droplet sizes (1 μm — 2 μm diameter). Above a critical volume fraction , these systems exhibit solid-like behavior and a yield stress can be detected. Previous experiments suggest that......

SWITCHING METAL COMPLEXES VIA INTRAMOLECULAR ELECTRON TRANSFER: CONNECTIONS WITH SOLVATOCHROMISM

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 21 gennaio 2021 Metal complexes that can exists in two different charge distributions often exhibit dramatic color changes when switched between them. The underlying spectral changes are fundamentally related to the switchable behavior. In valence tautomeric (VT) systems, the transition is a stimulated, reversible......

DESIGN STRATEGIES TOWARD TRANSITION METAL SELENIDE BASED CATALYSTS FOR ELECTROCHEMICAL WATER SPLITTING

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 21 gennaio 2021 Electrochemical water splitting is the most direct and popular method to obtain hydrogen. However, the high activation barrier for water splitting greatly hinders the large-scale hydrogen production, inspiring the necessity of using catalysts for the hydrogen evolution reaction and oxygen evolution......
