Surface functionalization of a polyurethane surface via radio-frequency cold plasma treatment using different gases
(
MDPI AG
, 2020 , Article)
Herein, the surface treatment of polyurethane (PU) films via air, O2, N2, Ar, and their mixtures were tested. The treatment was performed to incorporate new polar functionalities on the polymer surface and achieve improved ...
Antimicrobial modification of PLA scaffolds with ascorbic and fumaric acids via plasma treatment
(
Elsevier B.V.
, 2020 , Article)
An optimal medical scaffold should be biocompatible and biodegradable and should have adequate mechanical properties and scaffold architecture porosity, a precise three-dimensional shape, and a reasonable manufacturing ...
Light-Responsive Hybrids Based on Carbon Nanotubes with Covalently Attached PHEMA- g-PCL Brushes
(
American Chemical Society
, 2021 , Article)
Carbon nanotube (CNT)-based materials allow for the direct conversion of light into heat and then into mechanical force in the so-called photo-mechanical effect. This effect has been observed almost solely in the form of ...
Dry sliding tribological properties of a hard anodized aa6082 aluminum alloy
(
MDPI AG
, 2020 , Article)
The applications of aluminum and its alloys are still limited by low hardness and low wear resistance properties. Surface modifications, such anodizing and plasma electrolytic oxidation, represent a feasible way to overcome ...
Electrospun Polystyrene/PANI-Ag fibers for organic dye removal and antibacterial application
(
Elsevier Ltd
, 2020 , Article)
Herein we report superior dye-degradation performance for polyaniline-silver (PANI-Ag) nanoparticle coated on polystyrene (PS) electrospun membrane by in situ-polymerization method. Morphological study of the coated membrane ...
Fabrication of flexible electrically conductive polymer-based micropatterns using plasma discharge
(
Elsevier B.V.
, 2020 , Article)
In this work, laboratory prepared PANI and it's composite with carbon nanotubes (PANI/CNTs) were used for the fabrication of micropatterns on flexible polyethylene terephthalate (PET) substrate using the drop cast method ...
Computational Analysis of Wall Shear Stress Patterns on Calcified and Bicuspid Aortic Valves : Focus on Radial and Coaptation Patterns
(
MDPI
, 2021 , Article)
Calcification and bicuspid valve formation are important aortic valve disorders that disturb the hemodynamics and the valve function. The detailed analysis of aortic valve hemodynamics would lead to a better understanding ...
Epidemiology of SARS-CoV2 in Qatar's primary care population aged 10 years and above
(
BMC
, 2021 , Article)
There is an urgent need to elucidate the epidemiology of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) and characterize its potential impact. Investing in characterising the SARS-CoV2 will help plan and ...
Zinc and Boron Application at Different Phenological Stages Alleviates Tree Growth, Fruit Yield and Quality of Sweet Orange Cv. ‘Blood Red’
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
The deficiency of micronutrients, particularly zinc (Zn) and boron (B) has affected vegetative growth, yield and fruit quality of sweet orange in many citrus growing areas of Pakistan. The present study was conducted in ...
Corrosion inhibition performance of polyolefin smart self-healing composite coatings modified with ZnO@β-Cyclodextrin hybrid particles
(
Elsevier B.V.
, 2022 , Article)
Corrosion is a global problem that results in substantial economic loss and is life-threatening as well. Currently, the utilization of self-healing coatings involving smart carriers encapsulated with the appropriate ...
