Nature‐Inspired Functional Aerogel Fibers with Engineerable Core–Shell Morphology

Advanced Materials Technologies, EarlyView.
Nature‐inspired core–shell aerogel fibers are fabricated through coaxial wet‐spinning, which combines a polyimide shell with MXene core. The fibers exhibited absorption‐dominant EMI shielding, low thermal conductivity, and mechanical robustness, demonstrating multifunctional potential for wearable electronics and advanced smart textiles.

Hundreds of Nanocoulomb Electron Acceleration Driven by Multipetawatt Laser in Subcritical Density Plasmas

Advanced Photonics Research, EarlyView.
Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Operando TEM Study of Partial Oxidation of Methane Over Pd Nanoparticles

Advanced Science, EarlyView.
This operando TEM study reveals that Pd nanoparticles (NPs) catalyze the partial oxidation of methane (POM) by transforming into smaller, highly dynamic mixed‐phase Pd–PdO NPs, with active sites located at the interface between the two phases. Here, metallic Pd facilitates CH4 dehydrogenation, while PdO promotes C oxidation.

Enhancer Reprogramming Reveals the Tumorigenic Role of PTPRZ1 in Lung Squamous Cell Carcinoma

Advanced Science, EarlyView.
Lung squamous cell cancer (LUSC) is deadly due to lack of good treatments. Here, multiomics techniques are applied to LUSC tumors and find thousands of cancer‐specific enhancers controlling key genes. Interestingly, the gene PTPRZ1 is identified as a critical oncogene driven by the LUSC‐acquired enhancers. PTPRZ1 is activated by MDK, fueling cancer via
