Formation of arsenic sulfide on GaAs surface under illumination in acidified thiourea electrolytes
(
Elsevier
, 2011 , Article)
The present article reports the formation of arsenic sulfide films on GaAs by the potentiodynamic polarization in acidified thiourea (TU) electrolytes under photo-illumination. Oxidation of TU competes with the oxidation ...
Highly porous PtPd nanoclusters synthesized via selective chemical etching as efficient catalyst for ethanol electro-oxidation
(
Elsevier
, 2020 , Article)
Direct ethanol fuel cells (DEFCs) have received great interest owing to their high power density and environmental friendness. Nevertheless, the designing of active, durable, and efficient anode for DEFCs is a profound ...
Integrated lab-on-a-chip optical biosensor using ultrathin silicon waveguide soi mmi device
(
MDPI AG
, 2020 , Other)
Waveguides with sub-100 nm thickness offer a promising platform for sensors. We designed and analyzed multimode interference (MMI) devices using these ultrathin platforms for use as biosensors. To verify our design ...
Tailoring the reducibility and catalytic activity of CuO nanoparticles for low temperature CO oxidation
(
Royal Society of Chemistry
, 2018 , Article)
Copper oxide (CuO) nanoparticles have received considerable interest as active and inexpensive catalysts for various gas–solid reactions. The CuO reducibility and surface reactivity are of crucial importance for the high ...
Inner sphere oxidation of N,N′-ethylenebis(isonitrosoacetyleacetoneimine)copper(II) by N-bromosuccinimide in aqueous weakly acidic solutions
(
Springer Nature
, 2013 , Article)
The kinetics of oxidation of N,N'-ethylenebis(isonitrosoacetyleacetoneimine) copper(II) complex, CuL, by N-bromosuccinimide (SBr) in weakly aqueous acidic solutions was studied under pseudo-first-order conditions. Plots ...
Microstructure and mechanical behavior of hot extruded aluminum/tin-bismuth composites produced by powder metallurgy
(
MDPI AG
, 2020 , Article)
In this study, Al-BiSn composites were synthesized by a combination of microwave sintering and hot extrusion processes. The structural, morphological, mechanical, and thermal properties were investigated to elucidate the ...
The use of optical spectroscopy as abiomarker probe for fungi identification
(
Research India Publications
, 2013 , Article)
Spectroscopic techniques includinginfrared,Raman (FT-Raman) and ultraviolet spectroscopy (UV-Vis)spectroscopy were used to identify and differentiate three fungi within the same Aspergillus genus (A. fumigatus, A. terreusand ...
Response to: "Cancer risk due to contamination: Consideration from market basket survey in Qatar"
(
Elsevier
, 2014 , Other)
We welcome the comments on our article entitled “A market basket survey of As, Zn and Se in rice imports in Qatar: Health implications” (Rowell et al., 2014). The commenter opens up the debate on what constitutes a safe ...
Adsorption of 2, 4-dichlorophenoxyacetic acid onto date seeds activated carbon: Equilibrium, kinetic and thermodynamic studies
(2012 , Article)
Adsorption isotherm and kinetics of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide on activated carbon prepared from Barhi date seeds were determined from batch tests. The effects of contact time, initial herbicide ...
