A cellulose ionogel with rubber-like stretchability for low-grade heat harvesting

Research, Год журнала: 2024, Номер 7

Опубликована: Янв. 1, 2024

Achieving rubber-like stretchability in cellulose ionogels presents a substantial challenge due to the intrinsically extended chain configuration of cellulose. Inspired by molecular natural rubber, we address this using cyanoethyl as substitute for 1.5 hydroxyl on D-glucose unit This strategy innovatively triggers transformation molecules into coiled configuration, facilitating creation an ultra-stretchable ionogel free from any petrochemical polymers. The resultant demonstrates mechanical ductility comparable that rubber band, achieving elongation strain nearly 1,000% while maintaining tensile strength up 1.8 MPa and exhibiting biomodulus akin human skin, recorded at 63 kPa. Additionally, stretchable skin-like self-healing behavior, favorable biocompatibility, noteworthy thermoelectric properties, highlighted Seebeck coefficient approximately 68 mV K −1 . study delineates feasible approach developing biomass resources, potentially revolutionizing self-powered electronics integration with tissues skin.

Novel electrochemical sensor for the determination of potassium ions based on silver diethyldithiocarbamate as sensor material

Resources Chemicals and Materials, Год журнала: 2024, Номер unknown

Опубликована: Июль 1, 2024

Potassium is one of the macro minerals necessary for cellular functions, obtained from foods. Excessive amounts potassium can cause health problems. Determination in various samples, especially food and drug an important task. In this study, we developed a new potentiometric sensor selective to ions. The had detection limit 8.64 × 10-5 M concentration range 1.0 10-1–1.0 10-4 near–Nernstian behavior 49.0±4.32 mV/decade. exhibited response time 10 seconds, as well good selectivity, repeatability, wide pH working (4.0–11.0). was successfully applied sample different water samples with very high recoveries (>91.20%).
