Physics-Informed Neural Network-Enabled Forward Prediction and Inverse Design of Ring Origami. [PDF]

Adv Sci (Weinh)
This work presents a KRT‐PINN framework that integrates Kirchhoff rod theory with physics‐informed neural networks for the forward prediction and inverse design of ring origami consisting of closed‐loop rods. The framework predicts stable states of segmented rings with prescribed natural‐curvature profiles and determines the natural‐curvature profiles ...

Rod Origami (RodOri) Spring Metamaterials for Tunable Vibration Control via Tailored Structural Instabilities. [PDF]

Adv Sci (Weinh)
Rod Origami (RodOri) springs harness snap‐through instabilities of pre‐stressed curved rods with geometrically programmable buckling behavior. Integrating RodOri springs with distinct geometries yields multistable metamaterials that undergo stepwise reconfiguration via sequential snapping, achieving wide‐range tunability of stiffness and resonance ...

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Efficacy of the modified anvil grasper for laparoscopic intra-corporeal circular stapled anastomosis

Journal of Minimal Access Surgery, 2012
The traditional anvil grasper may be difficult to use for connecting the stem of an anvil with the centre rod of a circular stapler because the grasper holds the anvil completely still.

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

Advanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Synergistic Integration of Liquid Crystalline Ordering and Dynamic Networks for Ultrarobust Bismaleimide Vitrimers

Advanced Functional Materials, EarlyView.
A liquid‐crystalline bismaleimide vitrimer integrates local mesogenic organization with exchange‐active ester connectivity, achieving a glass‐transition temperature near 300°C while remaining reprocessable. Stress‐relaxation analysis and temperature‐dependent remolding reveal how segmental mobility, network rearrangement, and structural integrity ...

A Unified Approach for Out-of-Plane Forced Vibration of Axially Functionally Graded Circular Rods

European Mechanical Science, 2018
Out-of-plane forced vibration of axially inhomogeneous curved rods is examined by the Complementary Functions Method (CFM) in the Laplace domain. The material properties, Young’s modulus and density, of the circular rods are graded in the axial direction

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

Advanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...
