Leaching of Some Essential and Non-Essential Heavy Metals from Modern Glazed Ceramic Crockeries Imported into Qatar from China, India and Spain
(
OMICS International
, 2018 , Article)
In this study, the leaching potential of ceramic crockeries available in Qatar market has been evaluated
using inductively coupled plasma mass spectrometry (ICP-MS). Ceramic crockeries decorated with glaze matter
containing ...
Influence of Ag nanoparticles on state of the art MnO2 nanorods performance as an electrocatalyst for lithium air batteries
(
Elsevier
, 2018 , Article)
Abstract The need for an alternative and efficient electrocatalyst to replace Pt-based noble materials is a goal of prime importance in Li– air battery technology. In this work, novel silver nanoparticles-incorporated MnO2 ...
Collision/reaction cell ICP-MS with shielded torch and sector field ICP-MS for the simultaneous determination of selenium isotopes in biological matrices
(
Humana Press Inc
, 2011 , Article)
The determinations of selenium isotopes in biological samples were performed using both inductively coupled plasma collision/reaction cell quadruple mass spectrometer (CRC-ICP-QMS) and inductively coupled plasma sector ...
Capacitance of MnO2 Micro-Flowers Decorated CNFs in Alkaline Electrolyte and Its Bi-Functional Electrocatalytic Activity toward Hydrazine Oxidation
(
ESG
, 2017 , Article)
Well-dispersed MnO2 micro-flowers were grown directly on carbon nanofibers via a simple hydrothermal technique without any template. Structure and morphology were characterized by X-ray diffraction (XRD) and field-emission ...
Effective NiMn nanoparticles-functionalized carbon felt as an effective anode for direct urea fuel cells
(
MDPI AG
, 2018 , Article)
The internal resistances of fuel cells strongly affect the generated power. Basically, in the fuel cell, the anode can be prepared by deposition of a film from the functional electrocatalyst on a proper gas diffusion layer. ...
Synthesis and Physicochemical Studies of Perovskite Manganite La0.8Ca0.2Nn1−xCoxO3 (0 ≤ x ≤ 0.3)
(
The Korean Magnetics Society
, 2017 , Article)
The physicochemical properties of La0.8Ca0.2Mn1−xCoxO3 nanopowders as a function of Co content (x) have
been investigated. La0.8Ca0.2Mn1−xCoxO3 nanopowders were synthesized by sol-gel method and morphologically
and ...
Rare earth elements and 143Nd/144Nd isotope ratio measurements using tandem ICP-CRC-MS/MS: Characterization of date palm (: Phoenix dactylifera L.)
(
Royal Society of Chemistry
, 2017 , Article)
Herein, tandem inductively coupled plasma mass spectrometry with a collision/reaction cell (ICP-CRC-MS/MS) was used to accurately characterize the rare earth element (REE) pattern and the radiogenic isotope ratios of ...
Catalytic Degradation of 4-Ethylpyridine in Water by Heterogeneous Photo-Fenton Process
(
MDPI
, 2019 , Article)
In this work, the degradation of 4-ethylpyridine (4EP) in water by a heterogeneous photo-Fenton process (H2O2/Fe3O4/ultraviolet irradiation (UV)) was investigated. More rapid and effective 4EP degradation was obtained with ...
The potential impact data of Tylosin and Enrofloxacin veterinary antibiotics on germination and accumulation in barley seed as a forage crop and good dietary sources using LC/MS-MS
(
Elsevier
, 2019 , Article)
In this study, the phytotoxic effects caused by the exposure to five different concentrations of two veterinary antibiotics (Tylosin, and Enrofloxacin) that are commonly used for the treatment of farm animals as antibacterial ...
Investigation of Biochemical Alterations in Ischemic Stroke Using Fourier Transform Infrared Imaging Spectroscopy-A Preliminary Study.
(
MDPI
, 2019 , Article)
Brain damage, long-term disability and death are the dreadful consequences of ischemic stroke. It causes imbalance in the biochemical constituents that distorts the brain dynamics. Understanding the sub-cellular alterations ...
