Physicochemical and Compatibility Assessment
Published on 2025-02-20 by ?aneta Ciastowicz, Renata Pamu?a, ?ukasz Bobak, Andrzej Bia?owiec @MDPI
Abstract: This study evaluates the compatibility and innovative applications of unmodified vegetable oils, including rapeseed, sunflower, linseed, castor, and used cooking oils, in the production of sustainable polymeric materials, particularly polyurethane adhesives. Fatty acid composition was characterized using GC-MS, functional groups were identified by FTIR, and physicochemical properties, such as hydroxyl value, acid value, viscosity, and density, were measured using conventional analytical techniqu[...]
Our summary: This study evaluates the compatibility and innovative applications of unmodified vegetable oils in sustainable polymeric materials, particularly polyurethane adhesives. Castor oil was identified as the most suitable option for bio-based polyols and polyurethane production.

Effects of Compounding Cross-Linkers
Published on 2025-02-19 by Shunquan Liu, Run Zhang, Chenchao Fu, Tianshuo Zheng, Ping Xue @MDPI
Abstract: Due to excellent chemical resistance and impermeability, high-density polyethylene (HDPE) is widely used in petrochemical transportation, product packaging, sports equipment, and marine applications. Yet, with the wide variety of service environments, its mechanical and thermal properties do not meet the demand. In the present study, a compounding cross-linker comprising di-tert-butyl peroxide (DTBP) and triallyl isocyanurate (TAIC) is employed by combining with a two-step preparation process. H[...]
Our summary: Effects of Compounding Cross-Linkers: High-quality cross-linking reactions achieved for HDPE using DTBP and TAIC. Peak cross-linking degree, heat resistance, and mechanical properties significantly improved, showing potential for high-performance engineering materials.

Abstract: Hydrogenated amorphous silicon (a-Si:H) devices on flexible substrates are currently being studied for application in dosimetry and beam flux measurements. The necessity of in vivo dosimetry requires thin devices with maximal transparency and flexibility. For this reason, a thin (<10 µm) a-Si:H device deposited on a thin polyimide sheet is a very valid option for this application. Furthermore, a-Si:H is a material that has an intrinsically high radiation hardness. In ord[...]
Our summary: Hydrogenated amorphous silicon devices on flexible substrates for dosimetry and beam flux measurements. Thin a-Si:H device on polyimide sheet for in vivo dosimetry. Study of X-ray and proton response of charge-selective contact devices for dose measurements.
