Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, EarlyView.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

The transmissibility of vibration isolators with a nonlinear anti-symmetric damping characteristic [PDF]

, 2008
In the present study, the concept of the Output Frequency Response Function (OFRF), recently proposed by the authors, is applied to theoretically investigate the transmissibility of SDOF passive vibration isolators with a nonlinear anti-symmetric damping

Loading Mode Dependence of Twin‐Twin Boundary Formation in a Textured Magnesium Alloy

Advanced Materials Interfaces, EarlyView.
The structures of twin‐twin boundaries formed by interactions between twin variants sharing the same or different zone axes in a deformed magnesium alloy are demonstrated. Lattice distortion around complicated interfaces promotes grain refinement in the subsequent thermomechanical process, enhancing the mechanical performance of magnesium alloys ...

Characteristic analysis of a quasi-zero-stiffness vibration isolator

IOP Conference Series: Materials Science and Engineering, 2018
The frequency range over which a linear passive vibration isolator is effective, is often limited by the stiffness required to support a static load. And this can be improved upon by employing nonlinear negative stiffness elements to get a low dynamic stiffness.

Tunable Sensitivity in PAN/CNF/PEDOT:PSS Nanofiber‐Based Piezocapacitive Sensors

Advanced Materials Interfaces, EarlyView.
This study demonstrates highly tunable, flexible pressure sensors made from a nanofibrous composite of polyacrylonitrile (PAN) and carbon nanofibers (CNF) or poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). By adjusting filler type, concentration, and mat thickness, the sensors achieve large sensitivity improvements, stable ...

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.

A fast continuation scheme for accurate tracing of nonlinear oscillator frequency response functions [PDF]

, 2016
A new algorithm is proposed to combine the split-frequency harmonic balance method (SF-HBM) with arc-length continuation (ALC) for accurate tracing of the frequency response of oscillators with non-expansible nonlinearities. ALC is incorporated into the
