Pervaporation (PV) is a well-established membrane technique used in separation; especially dehydration of organic solvents. Along with other parameters such as permeate pressure and feed temperature; feed composition is an important parameter, which affects separation characteristics and membrane performance in pervaporation. In this paper, the separation characteristics of a hydrophilic polyvi...

A novel strategy for the direct synthesis of N-alkylated amides from nitriles, aldoximes and alcohols was proposed and accomplished in the presence of a Cp*Ir complex.

This study aimed to determine the impact of artisanal refinery operations on physicochemical and microbiological properties soil water in Igia-Ama, Tombia Kingdom, Rivers State, Nigeria. Physicochemical parameters along with concentrations heavy metals, polyaromatic hydrocarbons (PAHs), total petroleum hydrocarbon (TPH), benzene, toluene, ethylbenzene xylene (BTEX), polychlorinated biphenyls (P...

Analysis of the N-glycosylation pattern on antibodies is described using complementary mass spectrometric strategies based on both, top-down ESI-UHR-TOF and bottom-up LC-MALDI-TOF/TOF. Fast LC-ESI-UHR-TOF analysis, performed on the Bruker maXisTM, provides highresolution, high-mass accuracy (confident low ppm) data for both, intact antibodies and released antibody heavy chains allowing a rapid ...

Regioselective synthesis of quinolone-1,2,4-triazoles was established starting from 4-hydroxyquinol-2-ones. The strategy started by the reaction ethyl bromoacetate with 4-hydroxyquinoline to give corresponding oxoquinolinyl acetates, which reacted hydrazine hydrate afford hydrazide derivatives. Subsequently, hydrazides isothiocyanate derivatives acyl thiosemicarbazides. Finally, subjecting thio...
