Estimating crop-specific production technologies in Chinese agriculture: a generalized maximum entropy approach [PDF]

open access: yes
A Generalized Maximum Entropy (GME) approach is adapted to empirically estimate crop-specific production technologies in Chinese agriculture. Despite a modest behavior assumption about equal marginal returns of non-land inputs among crops, this method ...

Microcapsule‐Mediated Vibration‐Induced Emission for Real‐Time Visualization of Polymer Deformation

open access: yesAdvanced Optical Materials, EarlyView.
A mechanochromic microcapsule is reported that combines vibration‐induced luminescence (VIE) with mechanically controlled release functionality. By embedding the microcapsules into a polymer matrix, the conformational changes of VIE molecules can be precisely amplified into visual fluorescent color signals, enabling real‐time, high‐sensitivity ...

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.
