This study investigates alternative material compositions for flexible silicone-based dry electroencephalography (EEG) electrodes to improve the performance lifespan while maintaining high-fidelity transmission of EEG signals. Electrode materials were fabricated with varying concentrations of silver-coated silica and silver flakes to evaluate their electrical, mechanical, and EEG transmission p...

A TiO2-coated net with photocatalytic antibacterial properties that purifies water for practical use in developing countries was fabricated. The TiO2 particles were modified a silane coupling agent, aminopropyltriethoxysilane or hexadecyltrimethoxysilane, to improve particle dispersibility. comprises three layers: TiO2-silicone photocatalyst layer, silicone layer protect the substrate from oxid...

Abstract Silicone elastomers-based materials have been extensively involved in the field of biomedical devices, while their use is extremely restricted due to poor surface lubricity and inherent hydrophobicity. This paper describes a novel strategy for generating robust layered soft matter lubrication coating on polydimethylsiloxane (PDMS) silicone elastomer, by entangling thick polyzwitterioni...

Selenium nanoparticles (SeNPs) with a bright red colour have aroused worldwide attention due to their unique properties in selenium supplementation because of low toxicity and favourable bioavailability. A simple method was developed for making nanolayer on the inner surface Polyvinyl chloride (PVC) silicone tube. The were produced by reaction sodium selenite ascorbic acid. Red amorphous been s...

STATEMENT OF PROBLEM The success of most non-implant-retained extraoral prostheses depends on retention derived from skin adhesives. Part 1 of this study found that Skin-Prep Protective Dressing improved the retentive properties of adhesives and that Secure(2) Medical Adhesive was stronger than Epithane-3. Part 2 investigates the application of a second layer of adhesive to the prosthesis, whic...

The results of modeling acute myocardial infarction on 20 male Wistar rats aged 24 months are presented. Ischemic effect is carried out by local injection 1.5% sclerosant ethoxysclerol (0.25 ml) into the thickness myocardium under general anesthesia using non-traumatic needle with silicone coating, which allows to simulate minimal invasive animal's body, trauma, little duration intervention, lo...
