Effect of plasma treatment on accelerated pla degradation
(
BME-PT and GTE
, 2021 , Article)
Poly(lactic acid) (PLA) has been found to be important in various applications, such as in the medical, pharma-ceutical, and packaging industries. However, the long-term associated degradation process of PLA is a limiting ...
Sulfobetaine-based polydisulfides with tunable upper critical solution temperature (UCST) in water alcohols mixture, depolymerization kinetics and surface wettability
(
Academic Press Inc.
, 2021 , Article)
Hypothesis: Synthesis of a new family of polymers having a polydisulfide structure can be conducted from sulfobetaine-based derivative of natural (R)-lipoic acid. A polydisulfide backbone of polymer can be depolymerized ...
Electrochemical surface activation of commercial tungsten carbide for enhanced electrocatalytic hydrogen evolution and methanol oxidation reactions
(
Elsevier B.V.
, 2022 , Article)
The chemistry of electrocatalysts deals with multiple critical factors to facilitate the electrochemical reactions. Among those, the rate limiting depends on electrons transfer for chemisorptions of molecules in redox ...
Probing the fibrillation of lysozyme by nanoscale-infrared spectroscopy
(
Taylor and Francis Ltd.
, 2021 , Article)
Amyloid fibrillation is the root cause of several neuro as well as non-neurological disorders. Understanding the molecular basis of amyloid aggregate formation is crucial for deciphering various neurodegenerative diseases. ...
Experimental prediction of the elastic properties of nanocomposite cementitious materials based on nanoindentation measurements
(
American Scientific Publishers
, 2017 , Article)
This paper provides in depth novel exploration of the local mechanical properties of nanocomposite cement using the nanoindentation technique. The elastic properties of carbon nanotubes (CNTs)-reinforced and unreinforced ...
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 ...
Foamy phase change materials based on linear low-density polyethylene and paraffin wax blends
(
Springer Nature
, 2018 , Article)
Foamy phase-change materials (FPCMs) based on linear low-density polyethylene (LLDPE) blended with 30 wt.% of paraffin wax (W) were successfully prepared for the first time. The advantage of these materials is their double ...
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 ...
