Weatherability of Bio-Based versus Fossil-Based Polyurethane Coatings

open access: yesEngineering Proceedings, 2022
The use of bio-based feedstock for the formulation of protective coatings has been implemented in the increased industrial supply of building blocks synthesized from biomass. The alternation of traditional polyurethane coatings by bio-based polyurethanes

Stretchable Carbon and Silver Inks for Wearable Applications

open access: yesNanomaterials, 2021
For wearable electronic devices to be fully integrated into garments, without restricting or impeding movement, requires flexible and stretchable inks and coatings, which must have consistent performance and recover from mechanical strain.

Tailoring water structure with high-tetrahedral-entropy for antifreezing electrolytes and energy storage at −80 °C

open access: yesNature Communications, 2023
The anti-freezing property of electrolyte is crucial for aqueous batteries under extreme conditions. Here authors explore the relationship between tetrahedral entropy and the freezing behavior of aqueous electrolyte, and further develop anti-freezing ...

Physical and Tribological Properties of Nitrided AISI 316 Stainless Steel Balls

open access: yesMATEC Web of Conferences, 2016
AISI 316 austenitic stainless steel balls (diameters 5.0 and 12.0 mm, typical hardness 250 HV0.3) and flat samples (20×20×2.0 mm) were nitrided by a pulsed glow discharge Ar/N2 plasma. Hardness of the ball surfaces was analysed using Vickers indentation.

Effect of Al/Mg Ratio on the Microstructure and Phase Distribution of Zn-Al-Mg Coatings

open access: yesMetals, 2023
In contrast with studies such as those on the effect of a single elemental variable on Zn-Al-Mg coatings, Mg/Al is considered a variable parameter for evaluating the microstructure of Zn-Al-Mg coatings in this work, and the combined effect of the two ...

Optical and Physical Properties of Methyltrimethoxysilane Transparent Film Incorporated with Nanoparticles

open access: yesAdvances in Materials Science and Engineering, 2012
Methyltrimethoxysilane has been used as a base in the formation of transparent sol-gel coatings on glass substrates. Several types of alcohol were used as solvents in order to obtain the highest transparency and scratch hardness of the film.

Room temperature-curable, easily degradable, and highly malleable and recyclable vanillin-based vitrimers with catalyst-free bond exchange

open access: yesPolymer Testing, 2022
Development of bio-based vitrimers attracted significant attention due to these species’ excellent recyclability and renewability. However, most bio-based vitrimers require high-temperature curation and catalyst use.
