Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

Small, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

Advanced Materials Technologies, Volume 11, Issue 10, 22 May 2026.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across
