Ultrasensitive Diamond Cantilever‐Based Optical Microphone

open access: yesAdvanced Science, EarlyView.
The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...

Thermal Runaway in Sulfide‐Based All‐Solid‐State Batteries: Risk Landscape, Diagnostic Gaps, and Strategic Directions

open access: yesAdvanced Energy Materials, EarlyView.
Understanding the thermochemical reactivity of solid‐state components is critical to ensuring the safety of all‐solid‐state batteries (ASSBs) under abuse conditions. This review comprehensively investigates thermal runaway behavior in ASSBs, focusing on the interactions between active materials, sulfide solid electrolytes, and interfacial architectures.

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

open access: yesAdvanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Dissecting Extreme Price Fluctuations in Mineral Fertilizers: Regularities and Co‐Movements in Light of Global Food Security

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Extreme swings in food prices can put food security at risk. Fertilizer prices are among the main drivers of food prices. This work explores the recurrent behavior of the extreme global fertilizer price fluctuations underlying food price dynamics.
