A novel Y₄Al₂O₉/Y₂O₃ composite exhibits substantial resistance to CMAS infiltration at both temperatures at 1300 ℃ and 1500 ℃, without notable grain-boundary penetration by CMAS glass. More importantly, the incorporation of reaction active compositions in the composite accelerated the consumption of molten CMAS constituents and reduced its corrosive activity, which is recognized as the crucial principle for composition design of anti-CMAS materials. This work provides valuable insights that guide the design of composition and advancement of superior CMAS-resistant materials.

A new study  by Prof. XUE Tian from the University of Science and Technology of China (USTC), Prof. YAO Yonggang of the Kunming Institute of Zoology of the Chinese Academy of Sciences (CAS), and Prof. ZHAO Huan of Hefei University has revealed that chronic exposure to artificial light at night (LAN) can trigger depression-like behaviors by activating a specific neural pathway in the brain.

Optical computing confronts three fundamental bottlenecks: clock-rate constraints, chip-scale limits, and inter-core parallelism. While clock rates and chip scales approach technological limits, microcomb-driven parallel optical computing offers a viable path to boost computility by overcoming parallelism constraints. A team from the Chinese Academy of Sciences developed a parallel optical computing architecture with 100 wavelengths, pushing the boundary of computility. This breakthrough enables higher computing density and scalable, thread-level parallelism beyond conventional hardware limitations.

Using national rural data, this study finds that adaptive behaviors in China's grain production mitigate 52.5%–63.5% of high-temperature impacts. But they can't effectively reduce excessive precipitation impacts. Tech progress and input adjustments are key adaptation mechanisms.

Researchers have developed a humidity-resistant phosphorescent material using a simple and effective strategy of multi-component crosslinking in polyvinyl alcohol (PVA) films. The innovation enables ultralong phosphorescence (3.18 seconds) under high humidity (80% RH), enabling applications in anti-counterfeiting, data encryption, and wearable electronics.

Anode-free all-solid-state batteries (AFASSBs) are potential candidates for next-generation electric mobility devices that offer superior energy density and stability by eliminating Li from the anode. However, despite its potential to stabilize the interface between sulfide solid electrolytes (SEs) and anode-free current collectors (CCs) efficiently, a controllable approach to incorporating MoS₂ into AFASSBs has not yet been found. Herein, we propose a strategy for stabilizing the interface of Li-free all-solid-state batteries using controllable MoS₂ sacrificial thin films. MoS₂ was controllably grown on CCs by metal–organic chemical vapor deposition, and the MoS₂ sacrificial layer in contact with the SEs formed an interlayer composed of Mo metal and Li₂S through a conversion reaction. In the AFASSBs with MoS₂, Mo significantly reduces the nucleation overpotential of Li, which results in uniform Li plating. In addition, MoS₂-based Li₂S facilitates the formation of a uniform and robust SE interface, thereby enhancing the stability of AFASSBs. Based on these advantages, cells fabricated with MoS₂ exhibited better performance as both asymmetrical and full cells with LiNi_0.6Co_0.2Mn_0.2O₂ cathodes than did cells without MoS₂. Moreover, the cell performance was affected by the MoS₂ size, and full cells having an optimal MoS₂ thickness demonstrated a 1.18-fold increase in the initial discharge capacity and a sevenfold improvement in capacity retention relative to SUS CCs. This study offers a promising path for exploiting the full potential of MoS₂ for interface stabilization and efficient AFASSB applications.
