(Springer, 2018-12)Chemical modification of montmorillonite though popular may be expensive and environmentally noxious and can result in secondary contamination. Therefore, there is a need for eco-friendly and efficient treatment techniques. ...
-
(Wiley, 2022-08)The effect of various clays nanofillers on the photo-oxidation of polyamide 11 (PA11) has been investigated by accelerated ultraviolet (UV) test up to 780 h. Organo-modified montmorillonite, halloysite nanotubes, and ...
-
(Elsevier, 2020-12)Experimental studies, supported by comprehensive density functional theory (DFT) and Monte Carlo simulation studies have been carried out on 2-(2-hydroxybenzylidene)hydrazinecarboxamide (SEMISCAD) and 2-((p-tolylimino)me ...
-
(Wiley, 2021-03)In the last two decades, environmental experts have focused on the development of several biological, chemical, physical, and thermal methods/technologies for remediation of PAH-polluted water. Some of the findings have ...
-
(Elsevier, 2013-11)Various Cu/HZSM5-zeolites were prepared and their catalytic properties were investigated by productanalysis via GC/MS chromatography in order to trace down the mechanism of the gas phase one-stepoxidation of benzene to ...
-
(Elsevier, 2017-08)We recently showed that the selective extraction of aluminium from the amorphous phase of a South African ultrafine coal fly ash can be achieved via thermochemical treatment with ammonium sulphate for 1 h followed by aqueous ...

(Elsevier, 2017-08)Heavy petroleum fractions are produced during crude and synthetic crude oil refining processes and they need to be upgraded to useable products to increase their market value. Usually these fractions are upgraded to fuel ...
-
(Wiley, 2012-07)The composition of the surface film formed on pure iron was investigated in a solution of 0.05M NaOH and 0.05M NaCl. Raman spectra of the film were recorded in situ during anodic polarisation over the passive region after ...

(Wiley, 2018-08)A furano sesquiterpenoid, known as siphonochilone (1), is commonly reported as the major compound in the roots and the rhizomes of Siphonochilus aethiopicus together with related oxidized sesquiterpenoids (2‐5). As part ...
-
(Elsevier, 2010-02)A new method for the stereoselective synthesis of the (R,R)-b-hydroxy-a-alkyl fatty acid fragment of mycolic acids, via an asymmetric anti-aldol reaction is reported. The ‘mycolic acid motif’ fragment was prepared in three ...
