Advanced Functional Materials, EarlyView.Electrochromic polymer stability under overpotential is improved by inserting an ultrathin, transparent n‐doped poly(benzodifurandione) interlayer between indium tin oxide and a poly(3,4‐propylenedioxythiophene)‐based electrochromic polymer. The interlayer supports rapid switching at operating bias, then becomes resistive near +0.8 V to suppress excess

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes
Advanced Functional Materials, EarlyView.The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control
Advanced Functional Materials, EarlyView.A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

International Metals Reviews, 1978
AbstractThis review is an attempt to draw together available information on the subject of moulds for the continuous casting of steel. Particular attention has been given to the role of the gap in the heat-extraction process and. the influence of mould design, operating variables, steel chemistry, and lubrication type on the mould heat flux.

Annual Review of Materials Science, 1981
The continuous casting process is now firmly established in the world steel industry. This paper reviews the history of its development, the characteristics of plants using it, the quality of the steel produced, and finally its future development. In conventional ingot making, steel products are made by refining, ingotmaking, soaking, slabbing or ...
