Direct Catalyst Coating In article 2200332, Severin Vierrath and co-workers demonstrate the fabrication process of anion-exchange membrane water electrolyzer cells in a simplified way. The catalyst layers (black) are directly deposited onto anion exchange (yellow) via bar-coating. molecules split into hydrogen (white) oxygen (red). Cover illustration by Luca Bohn.

Hochhaus and James Talton, an associate professor and postdoctoral associate, respectively , in the university's Department of Pharmaceutics; and James Fitz-Gerald of the Naval Research Laboratory in Washington, DC, have begun using the new technique-pulse laser deposition-to coat glucocorticoids with thin layers of a biodegradable polymer. Glucocorticoids are the strongest and longest-lasting ...

Manufacturing of hardmetal tools often involves surface grinding, ion etching and final coating. Each stage throughout the manufacturing chain introduces surface integrity changes which may be critical for defining the final mechanical behavior of the coated tools. Within this context, an experimental test program has been developed to assess the influence of a coating (TiN) deposition on surfa...

In this work, a new type of block co-polymer additive, PE9400, was investigated for electrodepositing an ultra-low Sn coating in methanesulfonic acid (MSA) electrolyte. A thin coating with a loading of 0.7 gm 2 tin was fabricatedwith excellent uniformity and coverage on wet temper rolling steel (WTRS), when PE9400was used as an additive in the plating bath. Electrochemical measurements, real el...

In recent years, coating processes based on the impact of high-velocity solid particles such as cold spraying and aerosol deposition have been developed and attracting much industrial attention. A novel coating process called 'warm spraying' has been developed, in which coatings are formed by the high-velocity impact of solid powder particles heated to appropriate temperatures below the melting...

Fluorescent nanodiamonds (FNDs) are very promising fluorophores for use in biosystems due to their high biocompatibility and photostability. To overcome their tendency to aggregate in physiological solutions, which severely limits the biological applications of FNDs, we developed a new non-covalent coating method using a block copolymer, PEG-b-P(DMAEMA-co-BMA), or proteins such as BSA and HSA. ...
