We observe the assembly of CdS nanorod superlattices by the combination of a DC electric field and solvent evaporation. In each electric-field (1 V/microm) assisted assembly, CdS nanorods (5 nm x 30 nm) suspended initially in toluene were observed to align perpendicular to the substrate. Azimuthal alignment along the nanorod crystal faces and the presence of stacking faults indicate that both 2...

Employing detailed atomistic modeling we study the mechanisms behind ion binding to proteins and other biomolecules and conclude that (1) small, hard ions bind via direct ion pairing to charged surface groups and (2) large, soft ions bind to nonpolar groups via a solvent assisted attraction. Our predictions are in qualitative agreement with bulk solution data and may provide an important clue f...

The solvent–steam assisted gravity drainage is an oil recovery process that combines the advantages of thermal and miscible effects, it has been successfully tested, especially in Canada, where many heavy reservoirs are located. This method uses two parallel horizontal wells drilled one above other, upper injects steam solvent lower produces oil. not applied yet Brazil, there reservoirs, northe...

Merging of photo- and mechanochemical activation permitted studying the role of eosin Y in the borylation of aryldiazonium salts in a ball mill. Simultaneous neat grinding/irradiation of the reactants and the photocatalyst led to the formation of boronates in a molten state. On the other hand, the catalyst-free liquid-assisted grinding/irradiation reaction also led to product formation, featuri...

We report the mechanism and scope of “preferential enrichment”, which is an unusual symmetry-breaking enantiomeric resolution phenomenon that is initiated by the solvent-assisted solid-to-solid transformation of a metastable polymorphic form into a thermodynamically stable one during crystallization from the supersaturated solution of certain kinds of racemic mixed crystals (i.e., solid solutio...

We here report an easy and efficient strategy to prepare submicron-sized polymeric vesicles with tetrahydrofuran (THF) as a good solvent through temperature-assisted nanoprecipitation (TAN). While conventional nanoprecipitation did not yield vesicles from block co-polymers (PEG-b-PCL), TAN produced vesicles with morphology and membrane thickness similar to those obtained by film rehydration met...

In recent years, there has been increasing interest in the functional components of sweet potato because its nutritional and medicinal value. The aim this study is to analyse how much phenolic compounds composition (derived from caffeoylquinic acids) varies as a result cooking. Traditional techniques such as: boiling, oven roasting more processing microwave cooking were tested. Three varieties ...

Abstract Liquid-assisted grinding (LAG) has received wide attention in chemical synthesis field. Here, we reported that LAG provides a smart strategy to build macrocyclic cocrystal (MCC), achieving quick modification. The been assembled by electronegative permethylated pillar[5]arenes (EtP5) and electropositive ligands. We select three ligands with strong electron-deficient groups for preparati...
