'Green' Cr(III)-based electrodeposition of stainless steel-like FeCrNi: synthesis, mechanisms, material properties of films and micro-nanocomponents for bio-medical applications

Enrico Bertero

The electrodeposition (ED) of stainless steel (SS) -like FeCrNi alloys for miniaturised devices is appealing for bio-medicine as it would allow combining excellent material properties (e.g. corrosion resistance, hardness, bio-compatibility) at low-cost. Ho ...

Mitigating voltage losses in photoelectrochemical cell scale-up

Sophia Haussener, Ronald Ramiro Gutierrez Perez

In solar water splitting, efforts in scaling up the photoelectrochemical cell beyond laboratory scale have started to attract significant attention. Several large-area devices have been demonstrated, but typically the efficiencies are much lower than their ...

Tribological behaviour of galvanic gold coatings reinforced with silica nanoparticles

Stefano Mischler, Anna Neus Igual Muñoz

Electroplated composite Au/SiO2 coatings on a nickel substrate have been produced by dispersing an emulsion of silica nanoparticles (20 nm in diameter) in an industrial hard-gold bath. The tribological behaviour of the Au/SiO2 coatings with different SiO2 ...

Coatings with tailored electronic and optical properties for advanced glazing

Olivia Valérie Charlotte Bouvard

Modern envelope glazing relies on nanoscale coatings to meet a range of specific needs. Low emissivity coatings can improve the thermal performance of glazing thanks to a thin metallic film. However, the conductive nature of this layer leads to an attenuat ...

Color neutral nanocomposite nickel-tantalum oxide for electrochromic windows

Andreas Schueler, Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard

Electrochromic windows can darken on demand to limit the solar gains entering a building to reduce the risk of overheating, while preserving the view towards the exterior. Yet, the switching speed and contrast as well as the durability of commercial produc ...
