Metal halide perovskites (e.g., CsPbBr₃) have emerged as highly promising scintillator materials owing to their superior optoelectronic characteristics. However, their practical deployment is constrained by intrinsic structural instability and nonradiative recombination-induced energy loss. Herein, they show that Ni²⁺ doping constitutes a potent regulatory strategy for synergistically improving the scintillation performance and environmental robustness of CsPbBr₃ perovskite. Various characterizations combined with threotecial calculation indicate that the incorporation of Ni²⁺ dopants triggers lattice contraction, thereby enhancing the resistance to environmental perturbations. Ni-doping also passivates intrinsic defects and traps, leading to marked suppression of nonradiative recombination pathways. This synergy in as-prepared Ni-doped CsPbBr₃ leads to an 11-fold enhancement in photoluminescence intensity and a substantial increase in photoluminescence quantum yield from 56.0% to 93.7%. Notably, it delivers an exceptional light yield of 38428.5 photons MeV⁻¹, a low detection limit of 64.9 nGyₐᵢᵣ s⁻¹, and superior radiation tolerance. Furthermore, a flexible scintillation screen containing Ni-doped CsPbBr₃ enables high-resolution X-ray imaging with a spatial resolution of 16.6 lp mm⁻¹, notably surpassing that of the majority of reported perovskite-based scintillators. This study provides profound insights into the pivotal role of metal doping into halide perovskites for enhancing environmental stability in radiation detection technologies.

We demonstrated a facile FJH strategy to achieve the controlled synthesis of atomically dispersed Cu species via ultrafast heating-cooling process. By systematically regulating the pulse parameters, we successfully anchored isolated Cu species with a well-defined local coordination environment. The optimized photocatalyst exhibits an approximately 10-fold enhancement in photocatalytic CO evolution under simulated solar irradiation, offering a promising new pathway for clean fuel production and carbon capture

A team from the College of Chemistry and Chemical Engineering of Shaanxi University of Science and Technology and Functional Inorganic Materials Energy Conversion Laboratory started from “yarn” as a continuously processable and weave-integrable material unit. They designed a dynamic electrostatic cladding-spinning strategy that integrates a high-strength mechanical skeleton, a photothermal conversion shell, and thermoelectric waste-heat recovery into a single yarn platform.

A research paper by scientists at Fudan University presented BioPINN-LM, a hybrid framework that combines physics-informed neural networks and multimodal large language models to rapidly predict aortic aneurysm wall stress and generate interpretable biomechanical risk assessments.

Current clinical anti-obesity regimens mainly utilize GLP-1 or PPAR-γ agonists, which are restricted by post-withdrawal weight rebound and inflamed adipose microenvironments respectively. This study fabricates adipocyte-targeted nanocomposite microneedles (LRSGSG@MN) co-delivering rosiglitazone and semaglutide for immuno-metabolic therapy. Lipid carriers deliver rosiglitazone to activate PPAR-γ and mitochondrial biogenesis, while sustained semaglutide polarizes macrophages toward anti-inflammatory M2 to alleviate adipose inflammation, disinhibiting thermogenesis and reinforcing white fat browning. In high-fat-diet obese mice, the patch alleviates adiposity and glucolipid disorders and maintains weight steadily after treatment withdrawal. This work reveals peripheral immunomodulatory effects of semaglutide and establishes a long-acting adipose-targeted microneedle platform for durable obesity intervention.

Researchers in Lin Quan's research group at Jilin University have developed an injectable MXene-based hydrogel specifically for treating periodontitis. This hydrogel, named GQM, consists of oxidized gellan gum, quaternized chitosan, and magnesium-tannic acid-modified MXene nanosheets. It can be injected into periodontal pockets, overcoming the problem of traditional drugs' inability to remain within these pockets. Under near-infrared light irradiation, it can gently disrupt bacterial biofilms through photothermal activity, while the electrostatic effect of the QCS (quaternary cytosolic crystals) helps kill periodontal pathogens. Furthermore, the nanosheets promote electron transport, restore mitochondrial NAD+/NADH balance, and induce macrophages to transform into the M2 type. In a rat model of periodontitis, GQM combined with near-infrared light therapy reduced bacterial count, inflammatory response, and alveolar bone resorption. The MXene-based hydrogels treat periodontitis by disrupting bacterial biofilms and reprogramming immune metabolism, offering a novel strategy for its management.

To overcome the fragility of soft sensing materials under long-term cyclic loading, researchers have developed a highly durable "eutectogel" utilizing a novel nanoscale cavitation mechanism. By integrating this fatigue-resistant material into a smart glove with deep learning algorithms, the team achieved a 99.9% accuracy rate in real-time sign language recognition. This innovation paves the way for seamless communication and advances the durability of next-generation human-machine interfaces.

Researchers have developed a new material called davyne that changes colour in the near-infrared region. The colour change cannot be detected with the human eye, but only with a spectrometer or an infrared-sensitive camera. The material could be used, for example, as an invisible anti-counterfeit tag.
