Ni3N as an Active Hydrogen Oxidation Reaction Catalyst in Alkaline Medium

Xile Hu, Andreas Schueler, Anna Krammer, Josef Andreas Schuler, Weiyan Ni

Hydroxide-exchange membrane fuel cells can potentially utilize platinum-group-metal (PGM)-free electrocatalysts, offering cost and scalability advantages over more developed proton-exchange membrane fuel cells. However, there is a lack of non-precious elec ...

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 ...

In-situ and post annealing effect on the microstructure and the optical properties of black Cu-Co-Mn oxide spinel coating for Parabolic Trough Collector (PTC) applications

Andreas Schueler, Anna Krammer, Josef Andreas Schuler, Samaneh Daviran

The present paper deals with the deposition of Cu-Co-Mn oxides thin film by magnetron sputtering to produce a black selective coating for solar Parabolic Trough Collector (PTC) systems. The effect of temperature was studied between the nominal temperature ...

Predicting the thermal performance of thermochromic flat plate solar collectors

Andreas Schueler, Josef Andreas Schuler, Anna Krammer

A thermochromic vanadium dioxide (VO2) based absorber coating is proposed. The optical response of the multilayered absorber is first simulated, then, the spectral reflectance of the deposited absorber is measured. The determined solar absorptance and ther ...

From university to industry - challenges in upscaling optical microstructures for daylight redirection in buildings

Andreas Schueler, André Gabriel Kostro, Josef Andreas Schuler, Philippe Couty

In this paper we present some of the challenges faced when upscaling optical microstructures from a lab scale 1x1 cm sized proof of concept sample to a square meter sized object that can be installed in a building. The optical microstructure in question is ...

Solar heat gains through train windows: a non-negligible contribution to the energy balance

Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard, Luc Burnier

The sector of transportation accounts for about one third of the total energy consumption in Switzerland. A monitoring campaign of the energy consumption of a regional train revealed the critical energy-consuming systems. Heating, cooling and ventilation w ...

Microfabrication of curved sidewall grooves using scanning nanosecond excimer laser ablation

Patrik Willi Hoffmann, André Gabriel Kostro, Jing Gong, Josef Andreas Schuler, Georgios Violakis

Novel glazing with embedded micro-mirrors can significantly reduce the energy consumption due to cooling and lighting in buildings. Especially promising are large arrays of periodic micro compound-parabolic-concentrators (CPCs) with angular-selected transm ...

Development of a novel mechanical micro-engraving method for the high-aspect-ratio microstructures of an advanced window system

André Gabriel Kostro, Josef Andreas Schuler, Jing Gong, Antoine Robert Michel Delaunay

A transparent polymer film with embedded micro mirrors is developed, and it can be attached to a window glass pane for daylighting, improving visual comfort and reducing cooling load in buildings by redirecting sunlight. Despite existing cutting-edge techn ...

Towards novel glazing with seasonal dynamics based on micro compound parabolic concentrators

André Gabriel Kostro, Josef Andreas Schuler, Jing Gong

Thermal loss and overheating caused by glazing is a key issue in reducing CO2 emission and energy consumption of buildings. A novel glazing based on micro compound parabolic concentrators (CPCs) is proposed. The glazing consists of a polymer layer with emb ...
