Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion
Advanced Materials Technologies, EarlyView.This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

Advanced Materials Technologies, EarlyView.A MEMS‐integrated metamaterial filter enables continuous, low‐voltage spectral tuning in the long‐wavelength infrared (LWIR). The device employs extraordinary optical transmission in a dual suspended metasurface stack, where electrostatic actuation precisely controls the intermembrane air gap.

Advanced Materials Technologies, EarlyView.A flexible pressure sensor utilizing a 3D dual‐pore polyurethane structure is developed to overcome the intrinsic trade‐off between sensitivity and linearity. By inducing sequential buckling through distinct pore sizes and shapes, the device achieves highly linear and sensitive responses across a wide pressure range.

Flexural-torsional buckling of FRP thin-walled composite with various sections
Science and Engineering of Composite Materials, 2014 The flexural-torsional buckling of thin-walled pultruded fiber-reinforced plastic (FRP) members composed of unstiffened, stiffened cruciform- and I-shaped sections under uniform compressive loads was investigated using finite element methods (FEM).

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption
Advanced Optical Materials, EarlyView.ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Lateral-torsional buckling resistance of pultruded fibre reinforced polymer shapes [PDF]
The currently lack of design guidance for pultruded fibre-reinforced polymer member requires more study on their structural behaviours in order to provide structural designer with confidence when applying this material into civil engineering.

Advanced Robotics Research, EarlyView.A novel carbon fiber reinforcement for dielectric elastomer actuators enhances actuation force while decoupling electromechanical performance from the actuator's aspect ratio. Unlike conventional fiber reinforcements, it enables a uniform planar stretch state along the entire actuator.
