Ultrasensitive Diamond Cantilever‐Based Optical Microphone

Advanced 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 ...

Scalable Photoactive NO2‐Sensing Framework for Plant Health Monitoring

Advanced Science, EarlyView.
A highly sensitive and selective NO2 gas sensor operates at room temperature using only ambient light, eliminating the need for external heating. Based on a scalable, 3D TiO2 nanoarchitecture, the device is integrated into a wireless platform and deployed on a plant. It successfully demonstrates real‐time monitoring of gas‐induced physiological stress,

“Bio‐based Plastic? Hm, I've Never Seen It!”—A mixed‐methods investigation into consumer preferences for different packaging material of fresh apples and tomatoes

Agribusiness, EarlyView.
Abstract Packaging of fresh fruits and vegetables is standard in many grocery stores. This mixed methods study aims to identify the role packaging plays in consumer choice and what packaging material consumers prefer. We analyzed data from quantitative stated preference experiments with a quota sample of 485 consumers living in Germany.
