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

open access: yesAdvanced 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

open access: yesAdvanced 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

open access: yesAdvanced 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.

Tidal evolution of compact planetary systems

open access: yes
Depois da descoberta dos primeiros exoplanetas, novas missões espaciais foram concebidas com o propósito de descobrir e caracterizar planetas (e os seus sistemas) fora do Sistema Solar. Destas destaca-se a missão espacial Kepler por ter descoberto mais de 2000 exoplanetas na nossa galáxia. Com os seus dados observa-se que na distribuição dos rácios dos

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced 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.

Performance and Environmental Impact of Flexible Temperature Sensors on Cellulose‐Based Substrate

open access: yesAdvanced Electronic Materials, EarlyView.
Toward low‐environmental‐impact approach to thin‐film sensors fabrication using natural ingredient‐based triacetyl cellulose (TAC) substrate. Temperature sensors are fabricated and characterized based on thermal and mechanical performance. Substrate recovery is demonstrated by facile dissolution of a Mo‐based sensor in deionized water.
