A Robotic Testing Platform for Pipelined Discovery of Resilient Dielectric Elastomer Actuators
Advanced Science, EarlyView.This work introduces a robotic testing platform enabling high‐throughput, multi‐parameter lifetime mapping of linear dielectric elastomer actuators (DEAs). By integrating programmable high‐voltage control and automated electromechanical measurements, the system identifies material and operating conditions that double actuator lifetime.

Precommercial thinning stumps' susceptibility to Heterobasidion spp. [PDF]
, 2011 Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northern hemisphere, including Sweden. New results indicate that pre‐commercial thinnings could be at risk for Heterobasidion spp. infections.

Magnetoelectric BaTiO3/CoFe2O4 Thin‐Film Meshes for Neuronal Differentiation
Advanced Science, EarlyView.We engineer an epitaxial BaTiO3/CoFe2O4 magnetoelectric mesh that overcomes boundary‐induced mechanical clamping. Progressively reducing the mechanical constraint, from substrate‐clamped to PDMS‐transferred and ultimately freestanding, enhances magnetic‐to‐electric transduction and strengthens magnetoelectric coupling.

Advanced Science, EarlyView.As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Exfoliated‐MoS2 Gradual Resistive Switching Devices as Artificial Synapses
Advanced Electronic Materials, EarlyView.A vertical memristor based on untreated, exfoliated MoS2 is presented, revealing gradual resistive switching governed by Schottky barrier modulation at the MoS2/metal interface from the trapping/detrapping of charges. Furthermore, the device emulates synaptic‐like plasticity functions, including: potentiation, depression, and spike‐amplitude‐dependent ...
