In the past four years, transition metal vanadates have received booming attention as anode materials for lithium ion batteries (LIBs) due to their outstanding specific capacities, decent cycling performance and superior rate properties. Among them, Co3V2O8 is the most reported species. However ...

Pseudocapacitive charge storage has been regarded as a promising mechanism to achieve both high specific energy and power energy storage devices. Some pseudocapacitive anode materials show great high-rate performance, however, it remains a significant challenge to develop the cathode ones. Herei...

With a theoretically high capacity and suitable discharge/charge plateaus, lithium vanadates (such as Li0.04V2O5) can be used as cathode material for lithium ion batteries. Herein, Li0.04V2O5 nanowires are densely anchored onto reduced graphene oxide (rGO) nanosheets to form a Li0.04V2O5@rGO nan...

The nanostructuring of materials can solve the problem of low conductivity of the vanadate electrode, thereby increasing the potential for lithium storage performance. The traditional battery is prepared by coating active materials on current collector, which produces large contact resistance be...

Lithium vanadate nanowires have been electrodeposited onto a titanium (Ti) foil by a direct current electrodeposition without template. The morphology, crystal structure, and the effects of deposition voltage, temperature and time on the prepared samples were tested and presented. The as-prepare...

New 2-aminobenzamide-type histone deacetylase (HDAC) inhibitors were synthesized. They feature a sulfur-containing bicyclic arylmethyl moiety—a surface recognition domain introduced to increase in cellular uptake—and a substituted tert-amino group which affects physicochemical properties such ...

Semi-interpenetrating polymer network (semi-IPN) hydrogels were prepared by UV irradiation of water-soluble N-carboxylethyl chitosan (CECS) and 2-hydroxyethyl methacrylate (HEMA) aqueous solutions in the presence of D-2959 as photoinitiator. Hydrogels were characterized by using scanning electro...

The behavior of poly(2-hydroxyethyl methacrylate) (PHEMA) polymer monolayer spread on water was studied under various experimental conditions. The influence of subphase pH and temperature, compression speed, elapsed time from the deposit of the monolayer and the recording of the surface pressure...

The dispersion copolymerization of 2-hydroxyethyl methacrylate (HEMA) with glycidyl methacrylate (GMA) in a toluene/2-methylpropan-1-ol mixture in the presence of Fe3O4 nanoparticles coated with oleic acid, produced monodisperse magnetic poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate)...

Acrylamide (AA), a probable human carcinogen, is present in high-temperature-processed foods, and has frequently been detected in humans worldwide. In the present study, the levels of a major AA metabolite, N-acetyl-S-(2-carbamoylethyl)-cysteine (AAMA) were measured in urine samples collected in...

Several 2-(hydroxyethyl)-substituted alkylamines like 1,4-bis(2-hydroxyethyl)piperazine, N,N-bis(2-hydroxyethyl)methylamine, N,N-bis(2-hydroxyethyl)ethylamine, and N,N,N-tris(2-hydroxyethyl)amine as well as their derivatives (HCl salts, a borate and trimethylsilylethers) were subjected to electr...

Polymer networks interpenetrated by chitosan and 2-hydroxyethyl methacrylate (HEMA) were synthesized. The FTIR spectra confirmed crosslinking of chitosan and polymerization of HEMA. The swelling properties were studied at different pHs and depend particularly on the chitosan content of the mater...

N,N-bis(2-hydroxyethyl)acetamide shows restricted rotation about the amide bond in both 1H and 13C NMR spectra rendering the two hydroxyethyl groups non-equivalent. A variable temperature study in CD3SOCD3 allowed estimation of the free energy barrier to rotation as 75.6 ± 0.2 kJ mol−1. Previou...

This paper reports on the development of a polymer inclusion membrane (PIM) for the selective separation of Sc(III) from other REM ions. A comparison is made of the performance of cellulose triacetate (CTA) based PIMs containing 2-thenoyltrifluoroacetone (HTTA), 2-ethylhexylphosphoric acid mono-...

By combining the structures of P227 and Cyanex 272, a nonsymmetric dialkylphosphinic acid USTB-1 was synthesized. Its structure was confirmed by 31P NMR, 1H NMR, MS and IR. Its pKa and purity were determined through potentiometric titration method. Its extraction and separation performance for R...

The addition of yttrium chloride (YCl3) to an activated carbon-supported Au catalyst (Au/AC) can markedly promote the catalytic performance of acetylene hydrochlorination to the vinyl chloride monomer (VCM). The structure and physicochemical features of the YCl3-modified catalysts (Y–Au/AC) wer...
