Core-shell 12-tungstophosphoric acid/TiO2 (HPW/TiO2) nanoparticles at 10 and 20% of HPW have been synthesized by simple in-situ sol- gel method. Characterization of the samples was carried out by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared (FTIR). The X-ray diffraction patterns of as prepared solid samples, indicated characterist...

OBJECTIVE Type 2 diabetes adversely affects the liver and kidney function tests. This study was conducted to determine that either the liver and kidney functions are disturbed in the patients having gestational diabetes mellitus (GDM). METHODS One hundred and three women with GDM, and 97 healthy pregnant women (HPW) in their third trimester were registered in the Obs/Gyn Unit of Khyber Teachi...

A series of HPW/CeO2 catalysts generated from 12-tungstophosphoric acid, H3PW12O40 (HPW), supported on ceria and presenting different tungsten loadings (2, 4.5, 9, 16, 40 wt% W) were prepared characterized by N2 physisorption, XRD, IR, Raman, UV-Vis. The characterization techniques suggested that low loading resulted in mainly isolated sites, while high produced polymeric or clusters. Those mat...

OBJECTIVE The objective of the study was to report the socio demographic risk factors of gestational diabetes mellitus (GDM). METHODS This study was conducted in the Institute of Chemical Sciences, University of Peshawar. In this study 103 GDM and 97 healthy pregnant women (HPW) were registered in Khyber Teaching Hospital (KTH), Peshawar, Pakistan. Women with gestational diabetes were diagnos...

We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW). The proposed PBS separates transverse-electric (TE) and transverse-magnetic (TM) modes using a bent lower HPW with vertical nanoscale gaps and a straight upper HPW with a horizontal nanoscale gap, respectively, without relying on an additional coupling region. This design ...

A Zn-exchanged heteropolyacid supported onto silica (Zn-HPW/SiO2) activates methane at 25 °C into Zn-methyl. At higher temperatures and with CH4/O2 or CH4/CO2, it gives methanol and acetic acid respectively.

the performance of msu-s and its forms modified with phosphotungstic acid (hpw) and nickel (ni) for the desulfurization and denitrogenation of model diesel fuel were studied. according to the results of the characteristic tests (n2 adsorption-desorption, xrd, sem, and nh3-tpd), heteropoly acid incorporation causes higher acidity along with a negligible loss of structural aspects, while ni impre...

In situ measurements of Brønsted acid sites (by titration with 2,6-di-tert-butyl-pyridine) and reduced centers (by UV–vis spectroscopy) were carried out on WOx–ZrO2 with catalysts at 2.9– 32.3 W/nm2 in order to probe how these species form and act as active sites during 2-butanol dehydration. The rate of 2-butanol dehydration (per W-atom) on WOx–ZrO2 reached maximum values at intermediate WOx s...
