Advanced Functional Materials, EarlyView.A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries
Advanced Functional Materials, EarlyView.Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (

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.

Progress in Structural Engineering and Materials, 1997
AbstractIn recent decades, the ductility and weldability of structural steels has improved considerably. Also, the developments in modern welding technology have led to a decrease in the fabrication costs of steel structures, especially when higher strength steels are used. This has created new opportunities for more economical applications of steel in

Metal Science and Heat Treatment, 1998
Steels have found wide application in modern aircraft and are the profile materials in some structures. They are used when a high specific strength, rigidity, fatigue limit, and high-temperature strength are required, for example, in the production of wing bars, longerons, ribs, landing gear parts, and gear transmission mechanisms.

1. In steels with 0.25–0.35% C and 10–14% Ni the mechanical properties after quenching (cooling in air) are approximately the same as for carbon-free maraging steels: σb=190−200 kg/mm2; δ=10–12%; ψ=45–50%;an=6–7 kg-m/cm2;ap=1.7–2.2 kg-m/cm2. Small cold plastic deformation (2–5%) substantially increases the strength characteristics: ΔσT=50−60 kg/mm2,

High strength austenitic steels
Metal Science and Heat Treatment of Metals, 1959‘Transitional’ steels have an unusual combination of mechanical properties. They may have a low yield stress (20–40 kg/sq. mm=28, 400–56, 900 psi) and a high tensile strength (100–200 kg/sq mm=142, 000–284, 000 psi). The mechanical properties of these steels depend mainly on the extent to which austenite decomposes into martensite in deformation, and ...

Favourable Steel Structures using High Strength Steels
ce/papers, 2021AbstractAs a part of the European RFCS‐project STROBE, HOCHTIEF Engineering has developed a calculation programme as the basis of a web‐tool for the design and optimization of steel beams. The programme is suitable for steel girders of normal strength and for high strength girders up to S690 including welded hybrid girders. In this paper, the developed

High-Strength, Low-Alloy Steels
Science, 1980High-strength, low-alloy (HSLA) steels have nearly the same composition as plain carbon steels. However, they are up to twice as strong and their greater load-bearing capacity allows engineering use in lighter sections. Their high strength is derived from a combination of grain refinement; precipitation strengthening due to minor additions of vanadium,
