Herein, a photoliquefiable hydrogel dressing (denoted as PCS gel) is proposed as promising therapeutic strategy for rapid anti‐scar skin regeneration of refractory wounds. Specifically, the gel exerts robust antibacterial effect via mild thermogenesis for multidrug‐resistant biofilm eradication, and timely regulates tissue redox homeostasis. Upon efficient alleviation of local immoderate inflammation, PCS gel fosters a favorable pro‐regenerative microenvironment by bridging swift transition of the inflammatory stage to the proliferative stage, and thus significantly promotes neoangiogenesis as well as epithelialization. Importantly, the gel simultaneously alters pro‐regenerative fibroblast subpopulations by effective suppression of CD36 receptor during this stage, and hence blocks <jats:italic>JUN</jats:italic> overexpression‐mediated dermal fibrotic scarring. Notably, by thorough testing on both murine infected wound models (including acute wounds, diabetic chronic wounds) and rabbit ear hyperplastic scar wound model, PCS gel aided by thermogenesis facilitates rapid normal skin‐like epithelial closure with no perceptible hyperplastic scars.

The strong magnon‐phonon coupling has great potential to overcome these challenges for weak magnetic detection. Here, an ultra‐compact and highly sensitive SAW magnetic field sensor based on a strongly coupled magnon‐phonon system is demonstrated, featuring a thin FeGaB film embedded in an acoustic cavity.

In addition, the influence mechanism of different substituents and polystyrene (PS) concentrations on NBD is analyzed from a microscopic perspective.
