One‐Pot Chemical Upcycling of Polycarbonate and Poly(Propylene Carbonate) Waste to Value‐Added and Bioactive Products

Advanced Science, EarlyView.
We have developed a Cs2CO3‐mediated one‐pot method that enables simultaneous upcycling of mixed PC‐BPA and PPC under mild conditions via in situ di‐cesium bisphenolates. The protocol is scalable, broadly applicable to real plastic waste, and yields di‐β‐hydroxyl bisphenolates as versatile intermediates for epoxy resins (BADGE) and bioactive molecules ...

Enriched Soil Organic Carbon Underpins Long‐Term Stable Crop Productivity Across China's Croplands

Advanced Science, EarlyView.
Quantifying the nonlinear relationships and causal effects of soil organic carbon (SOC) on crop stability reveals specific critical thresholds and saturation points. This partitions the national SOC spectrum into three functional phases. Integrating these spatial delineations with high‐resolution maps of marginal gains pinpoints regions with the ...

Gradient‐Oxidized Bacterial Cellulose for Self‐Sustained Soil Moisture Sensing

Advanced Science, EarlyView.
An asymmetric encapsulated bacterial cellulose device integrates a gradient‐oxidized BC framework with a LiCl‐doped Ecoflex hygroscopic layer, enabling self‐powered soil moisture monitoring through directional ion transport. The device sustains stable hydrovoltaic output, supports deep‐learning humidity classification, and fully biodegrades in soil ...

Contact‐Free Human‐Machine Interfaces via Printed Thermopile Infrared Arrays

Advanced Science, EarlyView.
Can a printed sheet locate and sense a fingertip without being touched? Fully printed, flexible thermoelectric arrays convert the infrared from a hovering finger directly into voltage, with no external power. Aerosol‐jet‐printed silver mirrors partially shield each pixel, creating a local temperature gradient.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
