Porphyrins are a group of heterocyclic macrocycle organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges (=CH−). Porphyrins have attracted much attention ...

Cerium (IV) sulfate tetrahydrate, Ce(SO4)2.4H2O used as a new inorganic solid acidic catalyst for the synthesis of polyhydroquinoline derivatives via four-component Hantzsch reaction of aromatic/aliphatic aldehydes, ...

In this research DFT calculations were used to investigate the neighboring effects on cheletropic reaction of 2,5-Dihydrothiophene sulfone(1). Structural properties and stereoelectronic behavior in the activation energy ...

We developed some Ultrafiltration (UF)  membranes based on polysulfone (PSF) and poly acrylic acid (PAA) mixture. The Ultrafiltration membraneswere prepared by the phase inversion technique using Dimethylformamide (DMF) ...

This work examined some physicochemical parameters of effluents from a Brewery Industry in Imo state. This company discharged effluents in non-compliance with the Nigerian National Regulations as confirmed from the Biochemical ...

An efficient sample extraction using solid-phase extraction coupled with liquid-chromatography was studied for the analyses of three different types and chemical group pesticides from drinking water. The extraction was ...
