4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing

open access: yesAdvanced Functional Materials, EarlyView.
A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Thermo‐Mechanically Recyclable Smart Textiles from Circularly Knitted Liquid Crystal Elastomer Fibers

open access: yesAdvanced Functional Materials, EarlyView.
Reprogrammable multi‐material smart textiles knitted from liquid crystal elastomer fibers undergo 2D and 3D deformation under thermal and photo stimuli. Circularly knitted tubular structures reversibly contract in radial and axial directions, enabling autonomous climbing, liquid release, and micro pumping.

Trifluoromethoxylated Electron Acceptor Enabling Ternary Organic Solar Cells with over 20% Power Conversion Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT In this work, we introduce a trifluoromethoxy (OCF3) group as a pseudo‐halogen terminal group design for non‐fullerene acceptors, which combines strong inductive electron‐withdrawing ability with moderate resonance donation. The as‐synthesized BTP‐OCF3, when benchmarked against its methoxy analogue BTP‐OCH3, demonstrates narrowed bandgap ...

Limited Angle Torque Motors Having High Torque Density, Used in Accurate Drive Systems

open access: yesActa Polytechnica, 2011
A torque motor is a special electric motor that is able to develop the highest possible torque in a certain volume. A torque motor usually has a pancake configuration, and is directly jointed to a drive system (without a gear box). A limited angle torque

Nano‐Engineered Titanium Implants Loaded With Gingival Fibroblasts‐Derived Microvesicles Enhance Early Osseointegration And Soft Tissue Attachment In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
Our study showed that human primary gingival fibroblast–derived microvesicles on nano‐engineered titanium implants promote early osseointegration and soft‐tissue attachment in vivo. ABSTRACT Titanium dental implants require both reliable osseointegration and peri‐implant soft tissue seal formation to ensure long‐term success. While osseointegration has
