A solute-saturated supercritical fluid loading (SSFL) process was proposed to load 2-phenylethyl alcohol (PEA) in silica and activated carbon (AC). The adsorption and loading amounts of PEA in carries were investigated at different temperatures (50.0–60.0 °C) and pressures (8.0–14.0 MPa) by a...

GM2-gangliosidosis, a subgroup of lysosomal storage disorders, is caused by deficiency of hexosaminidase activity, and comprises the closely related Tay-Sachs and Sandhoff diseases. The enzyme deficiency prevents normal metabolization of ganglioside GM2, usually resulting in progressive neurodeg...

The catabolism of ganglioside GM2 is dependent on the lysosomal enzyme β-hexosaminidase A and a supporting lipid transfer protein, the GM2 activator protein. A genetically based disturbance of GM2 catabolism, leads to several subtypes of the GM2 gangliosidosis: Tay-Sachs disease, Sandhoff disea...

The new gadolinium(III) nitrate complex [Gd(H2L)2(NO3)3(EtOH)]MeOH where H2L is N,N′-bis(5-methylsalicylidene)-4-methyl-1,3-phenylenediamine was obtained in template condensation reaction of 5-methylsalicylaldehyde with 4-methyl-1,3-phenylenediamine in presence of gadolinium(III) nitrate hexahy...

Some oxygen defective metal oxides, such as cerium and bismuth oxides, have recently shown exceptional electrostrictive properties that are even superior to the best performing lead-based electrostrictors, e.g. lead-magnesium-niobates (PMN). Compared to piezoelectric ceramics, electromechanical ...

In recent years, the focus of research in the conversion routes for the actinide nitrates into oxides for the generation IV nuclear fuel cycle have attracted rapidly growing interest. One process is the self-sustained exothermic reaction of Solution Combustion Synthesis (SCS) methodology. It was...

A simple, convenient and general method has been developed for the synthesis of α-aminonitriles by a one-pot three component condensation of aldehydes, amines and trimethyl silyl cyanide in acetonitrile in the presence of a catalytic amount of La(NO3)3·6H2O or GdCl3·6H2O.

A high degree of reproducibility for the thermal decomposition of lithium azide has been achieved. The pressure-time plots show induction, acceleratory and decay periods. The latter two are described by the Avrami-Erofeyev equation and the contracting sphere equation respectively. The activation...

Azide technology of SHS (SHS–Az) is based on the use of a solid powder of an azide (such as NaN3) as a nitriding reagent in the SHS process instead of gaseous or liquid nitrogen for synthesis of nitrogen-containing compounds. Sodium vapors also play a positive role by reducing the oxides on the...

Soaring demand for efficient and economic electric energy storage system has intensively promoted the development of rechargeable batteries. Lithium sulfur battery may be one of the most promising candidates in the frontier of modern electrochemistry owing to its high theoretical specific capaci...

Lithium azidohydridodiisobutylaluminate (1), prepared as a solution in THF from DIBAH and lithium azide at rt, transfers the azide rather than the hydride to the unsymmetrical epoxides regioselectively to produce vic-azidoalcohols in high yields.

On the basis of the mild transformation of alkenyl triflates into alkynes promoted by LiCl, a one-pot protocol using alkenyl triflate precursors was developed for copper-mediated azide–alkyne cycloaddition. This protocol may provide an opportunity of sequentially click reactions for the constru...

An efficient one-pot synthesis of 1,2,3-triazole-fused isoindoles from o-alkynylbenzaldehydes and trimethylsilyl azide (TMSN3) is reported. The reaction proceeds through the formation of a diazide intermediate and a subsequent intramolecular azide-alkyne cycloaddition, providing a novel access t...

The structural and optical properties of lithium azide were studied using density functional theory within the generalized gradient approximation. The crystal structures compare well with experimental data. The ionic character is manifested by the closeness of internitrogen distances to the calc...

SnSb alloy is a promising anode material for lithium-ion batteries due to its high specific capacity. However, the large volume change in the process of charge/discharge causes significant pulverizing of SnSb alloy particles, which leads to a rapid capacity fading. This paper reports the synthes...

Until recently most of the understanding achieved for solid explosives has been obtained using various semi-empirical approaches due to a major role of excitonic effects in the mechanisms of decomposition. Nevertheless, during the last two decades, thanks to the ongoing progress in iterative com...

The method for the synthesis of 6-imino-5-tetrahydro-1H-2-pyrrolylidenhexahydro-2,4-pyrimidinediones is described. It is shown that the reaction of phosphorus trichloride, 2-pyrrolidones and 6-aminopyrimidines brings to condensation producing 6-imino-5-tetrahydro-1H-2-pyrrolylidenhexahydro-2,4-p...

Structural analyses of UO2(NO3)2L2 [L = N-n-butyl-2-pyrrolidone (NBP), N-cyclohexylmethyl-2-pyrrolidone (NCMeP), and 1,3-dimethyl-2-imidazolidone (DMI)] have been carried out using X-ray diffraction method. These uranyl complexes were found to have a hexagonal bipyramidal structure. The bond dis...

A series of branched-chain analogs of diethyl malathion and malaoxon were prepared in which the “leaving group” consisted of either malonate, succinate, α-glutarate, or β-glutarate diethyl esters. The single-dose oral toxicities of these compounds as determined for female Duplin white mice s...

The affinity constants (K1a0) and the phosphorylation constants (kp) were determined for a series of homologs of diethyl malaoxon where the “leaving group” consisted of either mercaptomalonate, mercaptosuccinate, a-mercaptoglutarate or β-mercaptoglutarate esters. The Ka(mM) values with respec...
