Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

A polymer blend of n‐type OMIEC P(gNDI‐gT2) with insulating PMMA yields mechanically stabilized, anti‐ambipolar organic electrochemical transistors (OECTs) with tunable ionic‐electronic transport. This blending allows low‐power, fast‐spiking heterogeneous Hodgkin–Huxley neurons, enabling biomimetic frequency deconvolution and reservoir computing, which

Optimal redundancy control for robot manipulators
Optimal control for kinematically redundant robots is addressed for two different optimization problems. In the first optimization problem, we consider the minimization of the transfer time along a given Cartesian path for a redundant robot. This problem can be solved in two steps, by separating the generation of a joint path associated to the ...

Solution precursor plasma spraying enables the scalable fabrication of porous and disordered nickel‐iron‐aluminum oxide coatings as precious‐metal‐free anodes. Aluminum inhibits crystal growth, optimizes local atomic sites, and enhances charge and ion transport to accelerate reaction kinetics, leading to excellent performance and operational stability.

By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...

Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...
