Entropy-driven melting point depression in fcc HEAs
(
Elsevier
, 2022 , Article)
High Entropy Alloys (HEAs) are an increasingly dominant alloy design paradigm. The premise of entropic stabilization of single-phase alloys has motivated much of the research on HEAs. Chemical complexity may indeed help ...
Human herpes simplex virus-6 (HHV-6) detection and seroprevalence among Qatari nationals and immigrants residing in Qatar
(
Elsevier
, 2022 , Article)
BackgroundHuman herpes simplex virus-6 (HHV-6) is the causative agent of exanthema subitum. Transmission mainly occurs through salivary secretions, yet blood transfusions and organ transplantations have also been reported ...
In-situ growth of single-crystal plasmonic aluminum–lithium-graphene nanosheets with a hexagonal platelet-like morphology using ball-milling
(
Elsevier
, 2021 , Article)
Metal-graphene nanocomposites and plasmonic metal nanoparticles are two nanoscience fields of a rapidly growing interest due to their potential in advanced applications. In this study, we combine both fields by synthesizing ...
A simple method for developing efficient room temperature reduced graphene oxide-coated polyurethane sponge and cotton for oil-water separation
(
Taylor & Francis
, 2022 , Article)
Oil spilled during transportation, domestic, and industrial usage causes grave water and soil pollution. Therefore, oil recovery through absorption or separation from water has been a challenge to the scientific community. ...
Enhanced tensile strength, fracture toughness and piezoresistive performances of CNT based epoxy nanocomposites using toroidal stirring assisted ultra-sonication
(
Taylor & Francis
, 2021 , Article)
The importance of proper CNT dispersion is still the main challenge in CNTs doped epoxy nanocomposites. Therefore, this study was aimed to investigate the effect of toroidal stirring-assisted sonication on final mechanical, ...
The effects of structural integrity of graphene on the thermoelectric properties of the n-type bismuth-telluride alloy
(
Elsevier
, 2021 , Article)
This study examines the effects of the structural integrity of graphene on the thermoelectric properties of n-type bismuth telluride alloy. Graphene/Bi2Te2.7Se0.3 composites were prepared via mechanical alloying and spark ...
Visible light-driven metal-oxide photocatalytic CO2 conversion
(
John Wiley & Sons, Ltd.
, 2015 , Article)
In this work, nine photocatalysts were prepared by a conventional solid-state reaction method. The samples were characterized by X-ray diffraction, UV–Vis diffuse reflectance spectroscopy, surface area measurements based ...
Design of Titanium Alloy Femoral Stem Cellular Structure for Stress Shielding and Stem Stability: Computational Analysis
(
MDPI
, 2022 , Article)
The main objective of this study is to design titanium alloy femoral stems with cubic porous structures that will be able to reduce stress shielding and promote stem stability. These porous structure designs were introduced ...
Needle-free injection: Dental infiltration anesthesia
(
Elsevier
, 2021 , Article)
This study aimed to develop an optimal Needle-Free Liquid Jet Injection (NFLJI) technique for dental infiltration anesthesia and evaluate its clinical safety and feasibility. The fluid dynamics of NFLJI in the dentoalveolar ...
Aragonite toothpaste for management of dental calculus: A double-blinded randomized controlled clinical trial
(
Wiley
, 2022 , Article)
Objectives: Aragonite from animal origin such as cuttlefish bone powder is an abrasive with hardness properties ideal for calculus removal. The purpose of this randomized controlled trial was to test the efficacy of a ...
