Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
Advanced Materials Technologies, EarlyView.A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Characteristics of lightly loaded fan rotor blade wakes [PDF]
Low subsonic and incompressible wake flow downstream of lightly loaded rotor was studied. Measurements of mean velocity, turbulence intensity, Reynolds stress, and static variations across the rotor wake at various axial and radial locations were ...

Advanced Materials Technologies, EarlyView.An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Experimental study on regaining the tangential velocity energy of axial flow pump
Energy Conversion and Management, 2003 Axial flow pumps are widely used in a wide range of applications. Although a different range of axial pump designs can be observed, axial flow pumps are usually designed for high flow rate and low pressure applications. In this study, two different axial flow pump impellers with and without guide vanes are experimentally investigated.

Journal of Mathematical Analysis and Applications, 1997 The author performs a nonlinear stability analysis using a multi-scales perturbation procedure for the instability of two layers of immiscible, inviscid, arbitrarily compressible fluids in relative motion. For modes of all wavenumbers on, or in the stable neighbourhood of, the linear neutral curve, the nonlinear evolution of the amplitude of the linear

Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications
Advanced Materials Technologies, EarlyView.We report a sub‐terahertz absorber made of biodegradable cellulose‐nanofiber (CNF), potentially useful for B5G/6G devices to achieve electromagnetic compatibility in an eco‐friendly way. The absorber is 120 µm thick and consists of two carbon‐nanotube‐dispersed CNF layers and one pure CNF layer.

Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.
