Summary: Performance degradation and loss of function due to mechanical stiffening caused by water evaporation and freezing limit the application of hydrogel-based electronics. In this study, a liquid-free electronic skin (e-skin) based on dry poly(ethylene glycol)-based gel and conductive Ti3C2 MXenes is developed for wearable strain sensors. The fabricated e-skin shows superior mechanical performance, wide sensing ranges, temperature adaptability, and environmental stability. It also maintains high conductivity and cycling stability even after 6 months. The e-skin sensors are used to provide guidance on body alignment and posture awareness, reducing the risk of sports-related injuries.

Summary: In this study, a highly stretchable and sensitive strain sensor was successfully fabricated by constructing an ionogel/silver conductive network. By utilizing a transmetalation reaction, the copper atoms in the copper/ionogel nanocomposite were transformed into larger silver atoms, resulting in a silver/ionogel nanocomposite with high conductivity. The conductive ionogel, acting as a polymer substrate, could connect the cracks of the silver conductive network during stretching, leading to high stretchability of the nanocomposite. The obtained strain sensor exhibited high sensitivity in a wide sensing range and could detect various human activities.

Summary: In this study, a conductive, stretchable, hydro-biodegradable, and highly robust cellulose/PEDOT:PSS hybrid film is fabricated. Through the synergetic interplay of a conductivity enhancer, nonionic fluorosurfactant, and surface modifier, the mechanical and electrical properties of the stretchable hybrid film are greatly improved. The stretchable cellulose/PEDOT:PSS hybrid film achieves a limited resistance change of only 1.21-fold after 100 stretch-release cycles (30% strain) with exceptionally low hysteresis, demonstrating its great potential as a stretchable electrode for stretchable electronics.

Summary: Chemical looping combustion (CLC) is a technique that utilizes oxygen carriers (OCs) to transfer oxygen and heat between fuel reactor and air reactor. The attrition of OCs is a major impediment to the large-scale application of CLC technology. In this study, the effects of different biomass ashes on the reactivity and attrition resistance of red mud OCs were investigated. The results showed that the rape straw ash promoted the reactivity of OCs, while the bagasse ash improved the attrition resistance. The corn straw ash was found to be an effective material for strengthening the skeleton structure of OCs, enhancing both reactivity and attrition resistance.
