Tribological properties of gold matrix composite coatings with carbon nanocapsules containing ionic liquid lubricants

Stefano Mischler, Anna Neus Igual Muñoz

Self-lubricating, gold matrix composite coatings were produced by electrochemical codeposition of carbon nanocapsules filled with ionic liquid (IL) from a colloidal galvanic bath on a nickel electrode. The tribological response of the composite coatings wa ...

Large-scale synthesis of crystalline g-C3N4 nanosheets and high-temperature H-2 sieving from assembled films

Nicola Marzari, Emad Oveisi, Kumar Varoon Agrawal, Mounir Driss Mensi, Davide Campi, Luis Francisco Villalobos Vazquez de la Parra, Zahra Nadizadeh

Poly(triazine imide) (PTI), a crystalline g-C3N4, hosting two-dimensional nanoporous structure with an electron density gap of 0.34 nm, is highly promising for high-temperature hydrogen sieving because of its high chemical and thermal robustness. Currently ...

Blue-shift ultrasensitivity using rhombus-shaped plasmonic crystal on Si3N4 membrane

Bahareh Ghadiani, Dordaneh Etezadi, Yasaman Jahani, Ershad Mohammadi, Foziyeh Sohrabi, Mahdi Tamizifar

Harnessing ultrasensitivity from optical structures to detect tiny changes in the targeted samples is the main goal of scientists in the field of sensor design. In this study, an uncommon rhombus-shape plasmonic structure is proposed for providing blue-shi ...

Optimization of front SiNx/ITO stacks for high-efficiency two-side contacted c-Si solar cells with co-annealed front and rear passivating contacts

Christophe Ballif, Franz-Josef Haug, Xavier Niquille, Andrea Ingenito, Sylvain Nicolay, Frank Meyer

In this contribution, we present an electron selective passivating contact metallised with a low temperature process to target front side applications in crystalline silicon (c-Si) solar cells. In addition to an interfacial silicon oxide (SiOx) and an in-s ...

A kilometre-range distributed relative humidity sensor

Luc Thévenaz, Li Zhang, Kenny Hey Tow, Tiago Filipe Pimentel Das Neves

Fibre optics sensors have been identified as very good candidates for environmental monitoring inside the silicon detectors operated at CERN’s Large Hadron Collider. In this study, we present the results from the first highly sensitive relative humidity di ...

Experiments and modelling for glow discharge plasmas applied to niobium sputter deposition in superconducting radiofrequency cavities

Thibaut François Hugo Richard

Thin film coatings are ubiquitous in modern daily lives, from the semi-conductor industry to aesthetic applications, and rely on the modification of a given material to enhance its surface properties. At CERN (European Organization for Nuclear Research), t ...

Rapid Performance Optimization Method for Photoelectrodes

Sophia Haussener, Yannick Kenneth Gaudy

We report the development of a rapid method for the performance optimization of photoelectrodes. The method requires as an input incident photon-to-current efficiency (IPCE) measurements of a material at two or more wavelengths, an estimation of the comple ...

Broadened Bandwidth Amplified Spontaneous Emission from Blue GaN-Based Short-Cavity Superluminescent Light-Emitting Diodes

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Denis Martin, Hua Zhang, Ching-Wen Shih

We report broad bandwidth blue superluminescent light-emitting diodes (SLEDs) based on a short-cavity active region. The dependencies of amplified spontaneous emission (ASE) output power and gain bandwidth on cavity length were investigated in devices whos ...
