The present investigation reported the controlled synthesis of Cd0.9Zn0.1S and Cd0.89Zn0.1Ni0.01S nanostructures by simple chemical co-precipitation route. XRD analysis confirmed cubic structure CdS on Zn doped Zn, Ni dual without any secondary/impurity phases no alteration in phase was noticed Zn/Ni addition. shrinkage crystallite size from 69 to 43 Å variation lattice constants micro-strain w...

The hydrothermal reduction of CO2 captured in aqueous solutions using metal reductants is a promising novel approach that achieves high yields conversion and selectivity, but it presents the limitation temperatures needed for reaction to take place. In this work, experiments combining several reductant metals (Zn, Al Fe), catalysts (Pd/C, Ni, Cu, Fe2O3 Fe3O4) (200, 250 300 ºC) were performed op...

The effects of Mg and Zn dopants on the catalytic performance Pt/Al2O3 catalyst were investigated for dehydrogenation perhydrodibenzyltoluene (H18-DBT) as a liquid organic hydrogen carrier. Al2O3 supports modified with to produce Mg-Al2O3 Zn-Al2O3 target loading 3.8 wt.% dopants. impregnated chloroplatinic acid solution catalysts Pt/Al2O3, Pt/Mg-Al2O3 Pt/Zn-Al2O3 0.5 Pt loading. Thereafter, cha...

A mild, green and highly efficient route for regio-selective amination of oxiranes was developed via incorporation of Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) cations onto the surface of hydroxyapatite-encapsulated γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp). Among six magnetically recoverable catalytic systems denoted as [γ-Fe2O3@HAp-MII], the catalyst in which M designated as Fe(II) showed t...

Designing efficient and cost-effective bifunctional catalysts is desirable for carbon dioxide oxygen reduction reactions (CO2RR ORR) to address neutralization energy conversion. Herein, a CO2RR ORR catalyst aqueous Zn-air battery (ZAB) self-driving electrolysis developed using atomically dispersed niobium anchored onto N-doped ordered mesoporous (Nb-N-C). The Nb-N-C atomic demonstrates activity...

Aqueous biphasic catalysis is a convenient approach to convert organic, partially soluble molecules in water. However, converting more hydrophobic substrates is much more challenging as their solubility in water is extremely low. During the past ten years, substantial progress has been made towards improving the contact between hydrophobic substrates and a hydrophilic transition-metal catalyst....

This paper argues that Information Technology (IT) needs to be demystified, through critical consciousness, for educators to focus on IT as a means to enhance learning. It goes on to define the technical, sociohistorical and political-ideological levels of IT and to identify four theoretical constructs: tutorial, machine-as-human, tool kit and catalyst. Pervading these constructs is the underst...
