First genotoxicity assessment of marine environment in Qatar using the local Pearl oyster Pinctada radiata
(
Elsevier
, 2017 , Article)
The Arabian Gulf countries’ marine environment has been subjected to increasing industrial development and anthropogenic pressure, leading to the growing introduction of contaminants into the marine environment, with a ...
Study of device instability of bottom-gate ZnO transistors with sol-gel derived channel layers
(
American Institute of Physics Inc.
, 2017 , Article)
In this paper, the authors report the device instability of solution based ZnO thin film transistors by studying the time-evolution of electrical characteristics during electrical stressing and subsequent relaxation. A ...
Crystallization and dielectric behavior of PLA and PHBV in PLA/PHBV blends and PLA/PHBV/TIO 2 nanocomposites
(
BME-PT and GTE
, 2019 , Article)
The morphology, crystallization behavior and mechanical properties of PLA, PHBV and their blends and nanocomposites with TiO 2 as filler were investigated. An uncommon morphological change was observed with increasing PLA ...
Labor Camp Surveys in GCC Countries: Group Quarter Subsampling
(
SAGE Publications Inc.
, 2019 , Article)
The Gulf Cooperation Council is a regional cooperation of six Middle Eastern countries-Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, Bahrain, and Oman. A common feature of these countries is the existence of many ...
Microalgal bioremediation of petroleum-derived low salinity and low pH produced water
(
Springer Netherlands
, 2019 , Article)
Due to the presence of toxic organic compounds and heavy metals, it is essential to treat the produced water before reuse or discharge to the environment. In this study, produced water sample was collected from a local ...
Role of TiO2 and carbon nanotubes on polyethylene, and effect of accelerated weathering on photo oxidation and mechanical properties
(
John Wiley and Sons Ltd
, 2019 , Article)
In this work, LLDPE-based composite films were prepared by melt mixing followed by compression molding to investigate the role of titanium oxide nanoparticles (TONPs) and/or multiwalled carbon nanotubes (CNTs) on the ...
Thermodynamics and kinetics of CH4/CO2 binary mixture separation by metal-organic frameworks from isotope exchange and adsorption break-through
(
Elsevier B.V.
, 2018 , Article)
We combine the isotope exchange technique (IET) with the conventional Sieverts method, microcalorimetry, breakthrough experiments and multi-scale modelling to comprehensively and quantitatively investigate the thermodynamics ...
Polyzwitterionic Hydrogels in Engines Based on the Antipolyelectrolyte Effect and Driven by the Salinity Gradient
(
American Chemical Society
, 2019 , Article)
In this paper, we propose and investigate an original approach to energy conversion based on polyzwitterionic hydrogels, which exhibit an antipolyelectrolyte effect that enables them to swell in salt water and shrink in ...
Stretchable Electrospun PVDF-HFP/Co-ZnO Nanofibers as Piezoelectric Nanogenerators
(
Nature Publishing Group
, 2018 , Article)
Herein, we investigate the morphology, structure and piezoelectric performances of neat polyvinylidene fluoride hexafluoropropylene (PVDF-HFP) and PVDF-HFP/Co-ZnO nanofibers, fabricated by electrospinning. An increase in ...
Sugar alcohol provides imaging contrast in cancer detection
(
NLM (Medline)
, 2019 , Article)
Clinical imaging is widely used to detect, characterize and stage cancers in addition to monitoring the therapeutic progress. Magnetic resonance imaging (MRI) aided by contrast agents utilizes the differential relaxivity ...
