A mechanochemical synthetic method of preparing LiCoO2 coated by MOF-derived metal oxide composites is introduced. Mono-dispersed ZrO2 and Al2O3 are applied as protection layers. These composites show 148 mA h g(-1) at a current density of 2325 mA g(-1) and excellent thermal stability (55 °C).

We use FUND 3.5 to estimate the social cost of carbon dioxide, methane, nitrous oxide, and sulphur hexafluoride emissions. We show the results of a range of sensitivity analyses, focusing on the impact of carbon dioxide fertilization. Ignored in previous studies of the social cost of greenhouse gas emissions, carbon dioxide fertilization has a positive effect at the margin, but only for carbon ...

A comparative study investigating the effects of metal substitution on the photocatalytic activity of metal oxide cluster anions is presented. The study shows that metal functionalization can be used to alter the photochemical properties of monolacunary tungstate - based Keggin clusters (α-[TM(H2O)SiW11O39](n-) (M = Co(2+), Cu(2+), Ni(2+), Mn(2+))). It is demonstrated that the photoactivity for...

Synthesis and characterisation of new permethylpentalene (Pn*) zirconium bis(amido) Pn*Zr cyclopentadienyl mono(amido) complexes their reactivity with carbon dioxide.

Based on starch and series of alkyl benzene sulfonic acid as the materials, a novel carbon-based solid acid catalyst is synthesized using hydrothermal method. This catalyst exhibits much higher catalytic activity in the reaction of esterification of Mono-fatty alcohol polyoxyethylene maleate esters with 1,4-butanediol. The structure of carbon-based solid acid catalyst was charactered by IR and ...

Fatty acids with carbon chain lengths greater than 22 (VLCFA) have been detected in boar, ram, bull and human spermatozoa. Saturated and mono-unsaturated fatty acids were present in all spermatozoa but, except for human spermatozoa, polyenoic fatty acids were quantitatively the most important components. Marked differences in polyenoic fatty acid composition were observed. Whereas human spermat...

Ammonia (NH3) is produced from atmospheric nitrogen and hydrogen from a hydrocarbon source. Natural gas is the most commonly used hydrocarbon feedstock for new plants; other feedstocks that have been used include naphtha, oil, and gasified coal. Natural gas is favored over the other feedstocks from an environmental perspective. Ammonia production from natural gas includes the following processe...

The results of fabrication and characterization atomic structure nanocrystalline thin layers Y2O3 in cubic monoclinic phases is reported. Experimental data demonstrate crystalline ordering films with average grain size ~10-14 nm both for studied structures. Density Functional Theory (DFT) based simulations insignificant differences electronic these the bulk on surfaces. Theoretical modeling als...

In recent work, deep eutectic solvents (DESs) as ionic liquid analogues have been abundantly used in catalysis. Herein, vanadium phosphorus oxide (VPO) catalysts were synthesized from mono-, bi-, and tri- metallic DES of Nb, Zr, Mo metal dopants structure-directing agents electronic promoters for n-butane selective oxidation towards maleic anhydride. Higher MA selectivity larger conversion was ...

Rapid increase in automobile density and discharge of different types pollutants from are a serious issue for whole civilized world Bhakkar also.Vehicle emission automobiles released an enormous quantity toxic likewise nitrogen dioxide, sulfur carbon mono oxide, heavy metals particularly lead, cadmium environment produced harmful effects on germination growth plants. This study was aim to inves...
