Looking beyond the horizon
Looking beyond the horizon
Michel Calame is Head of Empa's Transport at Nanoscale Interfaces lab. The name says it all: the physicist aims to conduct research at the interface between physics and biology, where damp systems meet dry electronics and nano-devices display quantum mechanical effects because they are so minuscule.

Hydrogen as a pedalling aid
Hydrogen as a pedalling aid
An e-bike fueled with hydrogen instead of electricity? No, this is not a utopia, but reality: industrial gas specialist Linde has developed a hydrogen pedelec equipped with a compact fuel cell instead of the usual battery. Florian Freund was inspired by the invention for his Matura thesis: He developed a prototype with which the hydrogen e-bike can be refuelled safely at the H2 filling station on the Empa mobility demonstrator move.

Making a valuable resource usable with water
New reaction for converting methane into methanol In oil extraction sites, gaseous methane is simply burned, even though it could actually be a useful precursor material for fuels and products of the chemical industry. One way to make methane usable is to convert it to methanol. Being liquid, methanol is easier to transport than methane, and it can be used both as fuel and as raw material for the chemical industry.
