Laser‐Induced Local De‐Doping in Organic Semiconductors
Advanced Materials Technologies, EarlyView.The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications
Advanced Materials Technologies, EarlyView.A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2
Advanced Optical Materials, EarlyView.Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.

Helium Ion‐Induced Degradation Mechanisms in Optical Coatings for Space Applications
Advanced Optical Materials, EarlyView.Although low‐energy helium ions represent a significant source of degradation for optical coatings operating in space environments, their effects remain poorly understood. Systematic irradiation of over 150 metal and dielectric thin‐film samples at 4, 16, and 100 keV investigates the damage mechanisms and their impact on optical performance ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review
Advanced Robotics Research, EarlyView.Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
