2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

SmartBot, EarlyView.
ABSTRACT Electrostatic clutches offer immense potential for programmable variable stiffness in multi‐degree‐of‐freedom (DOF) robotic systems. However, their practical deployment in continuous motion is fundamentally bottlenecked by two challenges: spatial constraints in existing parallel‐plate configurations and the lack of electromechanical coupling ...

Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

Small, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Structural Control of Dual Emission in Coumarin Fluorophores for Visualizing Protein Droplet Maturation

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
A coumarin‐based dual‐emission fluorophore was designed to visualize the maturation of protein liquid droplets. Upon covalent conjugation to droplet‐forming proteins, ratiometric fluorescence imaging allowed real time monitoring of droplet maturation. This probe is applicable to the analysis of droplet formation and maturation mechanisms, as well as to
