Epidermal pH is an indication of the skin's physiological condition. For example, wound can be correlated to angiogenesis, protease activity, bacterial infection, etc. Chronic nonhealing wounds are known have elevated alkaline environment, while healing process occurs more readily in acidic environment. Thus, dermal patches capable continuous measurement used as point‐of‐care systems for monitoring skin disorder and process. Here, pH‐responsive hydrogel fibers presented that long‐term...

Petroleum-based polymer materials heavily rely on nonrenewable petrochemical resources, and damping are an important category of them. As far as green chemistry, recycling, concerned, there is urgent need for renewable recyclable biobased with high performance. Thus, this study designs synthesizes a series polylactic acid-based thermoplastic polyurethanes (PLA-based TPUs) composed modified acid polyols, 4,4′-diphenylmethane diisocyanate, 1,4-butanediol. PLA-based TPUs, prepared, display...
The operation of mechanical equipment inevitably generates vibrations and noise, which are harmful to not only the human body but also in use. Damping materials, can convert energy into thermal energy, possess excellent damping properties glass transition region alleviate problems caused by vibration noise. However, these materials mainly rely on petroleum-based resources, their temperatures (Tg) lower than room temperature. Therefore, bio-based with high at temperature must be designed for...
In this work, we present a disposable paper-based optical sensor arranged as barcode for monitoring food spoilage.
