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.

Tandem catalysis is a promising approach for enhancing the NO<jats:sub>2</jats:sub>RR and suppressing side effects; however, it is still challenged by the lack of well‐designed catalysts to drive this catalytic process. Herein, a catalyst is introduced, featuring Rh−Ru atomic‐pair dual sites that couple with interfacial oxygen‐containing species confined within a MoSe<jats:sub>2</jats:sub> lattice (RhRu‐MoSe<jats:sub>2‐x</jats:sub>O<jats:sub>y</jats:sub>), enabling the unprecedented selective conversion of NO<jats:sub>2</jats:sub><jats:sup>−</jats:sup> to NH<jats:sub>3</jats:sub> under a low potential.

Surface acoustic waves (SAWs), carrying coherent gigahertz‐frequency phonons, provide a platform to achieve strong coupling between SAW phonons and quasiparticles like magnons. SAWs devices also utilize the delta‐<jats:italic>E</jats:italic> or delta‐<jats:italic>G</jats:italic> effect for magnetic field sensing, achieving an ultra‐low limit of detection (LoD) down to tens of picotesla. Concomitant disadvantages include unidirectional response, millimeter size, complex structure, and fabrication still remain. 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 the strong coupling regime, the SAW frequency exhibits anti‐crossing and responds dramatically to external magnetic fields, enabling high sensitivities. Notably, within the anti‐crossing region, a frequency sensitivity of 600 kHz/Oe and a phase sensitivity of 44 °/Oe are achieved. Combined with phase noise evaluation, the LoD is determined to be 126 pT/Hz<jats:sup>0.5</jats:sup> @ 10 Hz and 27 pT/Hz<jats:sup>0.5</jats:sup> @ 100 Hz.

Here, the magnetic behavior of two-dimensional (2D) MnTe is investigated, specifically atomically-thin monolayers (MLs) and bilayers (BLs) grown on graphene/Ir(111) substrate, by combining experimental scanning tunneling microscopy, X-ray photoelectron microscopy, X-ray absorption spectroscopy, and X-ray magnetic circular dichroism with density functional theory calculations. It is found that while ML and BL MnTe adopt atomic structures with symmetries incompatible with altermagnetism, they exhibit intriguing magnetic phases: the BL forms a highly-robust layered antiferromagnet with in-plane spin anisotropy, whereas the ML presents characteristics compatible with spin-glass behavior below its freezing temperature, a phenomenon not previously observed in an atomically thin material.
