Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Ductile fracture prediction using a coupled damage model

, 2018
A crescente complexidade dos componentes obtidos pelo processo de estampagem de chapas metálicas e a redução dos ciclos de desenvolvimento de novos produtos colocaram novos desafios a esta tecnologia de conformação. Neste contexto, a simulação numérica do processo de estampagem de chapas metálicas assumiu um papel notório para enfrentar estes desafios.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Impact of Chitosan Incorporation on PBAT Composite: Thermal, Viscoelastic, Mechanical, and Morphological Properties

Journal of Applied Polymer Science, EarlyView.
The abstract explains the impact of various concentrations of chitosan on PBAT composite. Indeed, the composite is produced at increasing concentrations of chitosan (10%, 20%, and 30%). The decrease in the tensile strength with increased conc. of chitosan was recorded. Furthermore, the same impact was recorded for TGA analysis.

A Methodology for Ductile Fracture AnalysisBased on Damage Mechanics: Anlllustration of a Local Approach of Fracture

, 1989
Major solutions needed in frlcture analysis are (d) simple and accurate matedal characterization and (ô) easy transferring of malerial data lo cracked structures. ln !h€ proposed methodology. constitutive relationships. including cavity growth and coalescence, are used. Material characterization is based on the simple notched tension lest.
