Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

open access: yesAdvanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Spatial Homeotropic and Planar Liquid Crystal Alignment Patterning

open access: yesAdvanced Materials Interfaces, EarlyView.
A voltage‐assisted two‐step photoalignment methodology achieves precise micro‐patterning of alternating planar and homeotropic liquid crystal domains. Applying an AC electric field during in situ laser illumination minimizes phase retardation, reducing the required exposure dose. This cooperative mechanism enables high‐resolution spatial patterning and

Charge‐Trapping Multilayer Electrets for Partial Discharge Mitigated AlN Substrates

open access: yesAdvanced Materials Interfaces, EarlyView.
Multilayer electret films deposited on AlN substrates trap injected charge and generate an opposing electric field at the triple point. Finite‐element simulation shows the retained charge reduces the local field by about one third. Under steep high‐voltage pulses, the charged stacks raise the partial discharge inception voltage and lower the discharge ...

Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

open access: yesAdvanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...
