Ab Initio Molecular Dynamics Study of Quadrupolar Spin Relaxation in an Ionic Liquid

Journal of Computational Chemistry, Volume 47, Issue 3, 30 January 2026.
This study presents a methodology for describing the relaxation of nuclear spins (with I > 1/2), applicable to ionic liquids of a general nature. Based on ab initio molecular dynamics, we demonstrate the importance of explicit solvation in calculating the relaxation times of the quadrupolar mechanism.

An XPS study of the thermal degradation of polystyrene-clay nanocomposites [PDF]

, 2002
X-ray photoelectron spectroscopy, XPS, has been used to examine several polystyrene-clay nanocomposites. The accumulation of oxygen, from the almuniosilicate, on the surface of the polymer was observed, along with the loss of carbon.

Extended Synthetic Pathways Towards Dialkyl-Substituted Phosphanylboranes

Inorganics
Phosphine–boranes have garnered growing interest for their potential in catalysis and as building blocks for inorganic polymers. While various synthetic methods exist, flexibility to introduce diverse substituents on the P centers remains limited.

DIETHYLENE GLYCOL BASED DEEP EUTECTIC SOLVENTS AND THEIR PHYSICAL PROPERTIES

Studia Universitatis Babes-Bolyai Chemia, 2017
In this study, diethylene glycol (DEG), as a hydrogen bond donor (HBD), was mixed with three ammonium based salts, namely N,N-diethylethanolammnium chloride, tetra-n-butylammonium bromide and choline chloride, as well as two phosphonium based salts ...

Low molecular weight gelators (LMWGs) for ionic liquids: the role of hydrogen bonding and sterics in the formation of stable low molecular weight ionic liquid gels [PDF]

, 2017
Low molecular weight gelators capable of forming a gel with an ionic liquid are rare. We report the ability of 3 sugar based gelators from renewable resources (derived from isosorbide and mannitol) to form gels with 21 ionic liquids comprising a range of

Stimuli Responsive Ionogels for Sensing Applications - An Overview. [PDF]

, 2012
This overview aims to summarise the exiting potential of “Ionogels” as a platform to develop stimuli responsive materials. Ionogels are a class of materials that contain an Ionic Liquid (IL) confined within a polymer matrix.

A Carbocation Substituted Clay and its Styrene nanocomposite [PDF]

, 2004
A substituted tropylium ion can be ion-exchanged onto montmorillonite to give a novel organically-modified clay. One can prepare a polystyrene nanocomposite of this clay by emulsion, but not bulk, polymerization.
