Advanced Functional Materials, EarlyView.Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops
Advanced Functional Materials, EarlyView.We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

Advanced Healthcare Materials, EarlyView.Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

Abstract Metal-cutting tools offered the trade today are vastly superior in quality to tools of a decade ago. The factors that govern the life of metal-cutting tools made from carbon, alloy, and high-speed tool steels, namely, design, steel, and treatment, are discussed in this paper, particular stress being laid on the importance of ...

Tools steels are defined by their wear resistance, hardness, and durability which, in large part, is achieve by the presence of carbide-forming alloys such as chromium, molybdenum, tungsten, and vanadium. This chapter describes the alloying principles employed in various tool steels, including high-speed, water-hardening, shock-resistant, and hot and ...

Abstract This article presents fractographs of tool steels that failed by overload, fatigue, stress-corrosion cracking, and embrittlement. A small sampling of the fractographs in the article includes: the surface of an impact fracture in a shear blade of AISI L6 tool steel heat treated to a hardness of 55 HRC; the cracking of AISI M2 ...

Tool Steel Applications for Today's Tooling
Polymer-Plastics Technology and Engineering, 1986Abstract A Certain amount of extra initial cost in selecting the right mold material can minimize the much greate potential cost of mold operating expenses. Those often unnecessary expenses cost American industries millions of dollars in faulty/out-of tolerance molded parts, production losses, and have a serious impact on productivity as well as world ...
