Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

Advanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

BENDING ANALYSIS OF ORTHOTROPIC PLATES WITH ARBITRARY BENDING AND TORSIONAL STIFFNESS

Doboku Gakkai Ronbunshu, 2003
直交異方性平板を対象とした既往の研究では, Huber の仮定に代表されるような, 振り剛性に関する何らかの仮定を導入しているものが殆どである. しかし, Huber の仮定に拘束されない任意の曲げ・振り剛性を有する一般的なスラブについての解析的な研究は殆どなされていないのが現状のようである. このような研究の現況に鑑み, 本研究は任意の曲げ・涙り剛性を有する周辺固定平板, 三辺固定一辺自由平板, 二隣辺固定二辺自由平板の3種の直交異方性平板に対する解析について論じ, Huber の仮定の妥当性と適用範囲についての考察を行ったものである.

The stress distribution in the joints of vehicles chassis frames subject to torsion [PDF]

, 1978
The problem of warping inhibition in the joints, of commercial vehicle chassis frames is very important for the estimation. of stress distribution in the joints and the overall torsional stiffness of frames.

Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

Advanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

Theoretical framework for DOUBLE-DOUBLE composite plates under bending loads

Acta Scientiarum: Technology
This paper provides an insightful comparative analysis of laminated composite plates, focusing on two main stacking sequence groups: the traditional QUAD and the more recent DOUBLE-DOUBLE (DD) proposed by Professor Stephen Tsai.

Damage identification in a concrete beam using curvature difference ratio

, 2011
Previous studies utilising changes in mode shape or curvature to locate damage rely on the fact that the greatest change occurs around the defect. However, in concrete beams this fact is undermined due to the nature of the defect as distributed multi ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Texoskeletons: Developing the Fundamental Technologies for Creating Intelligent Soft Robotic Clothing With Integrated 1D Sensors and Actuators

Advanced Functional Materials, EarlyView.
ABSTRACT Traditional wearable exoskeletons rely on rigid structures, which limit comfort, flexibility, and everyday usability. This work introduces the fundamental technologies to create the first soft, lightweight, intelligent textile‐based exoskeletons (Texoskeletons) built using 1D sensors and actuators.
