A novel sprayable nanozyme dressing developed by Chinese researchers effectively treats aerobic vaginitis by combining antibacterial, anti-inflammatory, and microbiome-regulating properties. Tested in mice, the dressing not only alleviated infection and inflammation but also restored reproductive function and pregnancy rates, offering a promising non-antibiotic strategy for gynecological care.

Electronic devices capable of perceiving and responding to environmental changes are essential for applications in human–machine interaction, monitoring systems, and robotics. However, most existing devices suffer from the separation of sensing and actuation, leading to complex integration and limited responsiveness. In this study, the researchers introduce an intelligent thermoelectric device inspired by the interplay between sensory and muscle cells in sea anemones. The device seamlessly combines multimodal sensing with autonomous thermal actuation, enabling a closed-loop sensory–motor reflex. It demonstrates excellent temperature sensitivity (0.2 ℃) and pressure resolution (0.03 mm), owing to its three-dimensional architecture and hierarchical conductive network. Molecular dynamics simulations show that its dynamic hydrogen-bonding network enhances stress dissipation and interfacial adhesion, resulting in exceptional mechanical stability over 140,000 cycles. Furthermore, the device exhibits thermal self-adaptation, actively initiating a protection mechanism through thermoresponsive deformation to avoid high-temperature stimuli, with an adjustable actuation threshold. This work represents a significant advancement toward intelligent electronics capable of real-time decision-making and active environmental interaction.

Harvesting low-grade heat from both human metabolism and environmental waste through thermoelectric fabrics offers a sustainable pathway for wearable power generation. However, a critical challenge exists in establishing substantial temperature differentials for continuous thermoelectric generation while maintaining physiologically comfortable skin temperatures in dynamically variable environments.

With the quick development of flexible electronic devices such as foldable phones and wearable sensors, the demand for high-performance flexible transparent conductors (TCs) surges. Thin films of indium tin oxide (ITO), the traditional TCs, are increasingly constrained by their brittleness, limited indium sources, and high fabrication cost. The researchers at Hunan University and Xiamen University, China, have developed a supersaturation modulation strategy, enabling the efficient synthesis of ultra-long silver nanowires (Ag NWs) with high yield. The synthesized Ag NWs exhibit exceptional electrical conductivity, optical transparency, and mechanical flexibility, offering a promising alternative to ITO for next-generation TCs.

Triggering the anionic redox reactions at high voltage is an effective approach to boost the capacity of Li-rich layered oxides. However, the irreversible lattice oxygen release at high voltage and sluggish ion kinetics remain conundrums. Herein, a surface modifying coupling defect engineering strategy is proposed to improve the reversibility of anionic redox reactions and ion diffusion efficiency in Li-rich layered oxides. A LiNbO3 surface modification acts as an effective physical barrier to suppresses lattice oxygen release, thereby improving cycling stability of Li-rich layered oxide. Further, the oxygen vacancies in the LiNbO3 coating enhances the ion transport kinetics, strengthening rate capability. After 500 cycles, a high capacity retention of 83.3% can be achieved for the obtained cathode materials (CV-LLO) at 5 C, much higher than that of the pristine materials (LLO, 52.3%). Moreover, CV-LLO delivers a capacity of 169.9 mAh g-1 at 5 C, which was 65.1% of the capacity at 0.2 C, much higher than that of the pristine LLO (85.6 mAh g-1, 33.7%). This study provides insights into the construction of Li-rich layered oxide cathode with highly reversible anionic redox reaction and highly cycling stability for Lithium storage.

Random-pattern skin flaps are widely used to repair tissue defects, but surgeons still face a difficult question after reconstruction: which flaps will survive and which will fail?

After a stroke, nearly half of patients struggle to swallow – a dangerous condition called post-stroke dysphagia (PSD) that can lead to malnutrition, pneumonia, or even death.
