Tensile and fatigue data for irradiated and unirradiated AISI 310 stainless steel and titanium - 5 percent aluminum - 2.5 percent tin: Application of the method of universal slopes [PDF]
Irradiated and unirradiated tensile and fatigue specimens of AISI 310 stainless steel and Ti-5Al-2.5Sn were tested in the range of 100 to 10,000 cycles to failure to determine the applicability of the method of universal slopes to irradiated materials ...

A flexible, lightweight ankle brace made from 3D‐printed liquid crystal polymer metamaterials offers targeted support without restricting movement. Programmable stiffness provides protection during risky motions. Biomechanical tests suggest performance comparable to commercial braces with reduced bulk, highlighting potential for broader orthotic ...

This study designs an injectable porous hydrogel (HMs/MBs/ADSCs) integrating hollow microspheres for sustained BMP‐2 release to enhance adipose‐derived stem cells' paracrine effect. It accelerates tendon‐bone healing in rat rotator cuff injuries via spatiotemporal regulation: early AMPK‐mediated mitochondrial protection and late TGF‐β/Smad2/3‐driven ...

A structurally and functionally dual bionic bone adhesive is engineered through an organic–inorganic cohesion strategy, which significantly reinforces the adhesive's bone tissue adhesion as well as osteogenic activity. In a pioneering rabbit radius comminuted fracture model, the bone adhesive exhibits exceptional capability in immobilizing bone ...

Peripheral nerve injury necessitates alternatives to autografts. This study combines magnetic nanoparticles, oriented PCL fibers, and Ppy to create a conductive, magnetically active scaffold. In vitro and in vivo experiments demonstrated enhanced downstream pathways of calcium signaling, as revealed by transcriptome analysis.

High-temperature, low-cycle fatigue of advanced copper-base alloys for rocket nozzles. Part 1: Narloy Z [PDF]
Short-term tensile and low-cycle fatigue data are reported for Narloy Z, a centrifugally cast, copper-base alloy. Tensile tests were performed at room temperature in air and in argon at 482, 538 and 593 C using an axial strain rate of .002/sec to the -1 ...
