First measurements of 4th generation coolants24 March 2015
Searching for traces in the atmosphere

4th generation halogenated coolants and foaming agents have only been in use for a few years. They have replaced persistent greenhouse gases such as R134a, which were used in (car) air conditioning units, refrigerators and in a variety of foams. Empa researchers have now published first measurements on the atmospheric distribution and abundance of these new substances. They show that the new coolants are frequently used in Europe - and that their use is increasing.

Empa-led EU project "TREASORES" yields first results18 March 2015
Towards "printed" organic solar cells and LEDs

Flexible optoelectronic devices that can be produced roll-to-roll – much like newspapers are printed – are a highly promising path to cheaper devices such as solar cells and LED lighting panels. Scientists from "TREASORES" project present  prototype flexible solar cell modules as well as novel silver-based transparent electrodes that outperform currently used materials.

«Power-to-Gas» Technology Briefing2 March 2015
Key energy of the future

Our energy supplies are in a state of fundamental flux, the primary challenges being to reduce our CO2 emissions and to move from fossil and nuclear energy sources to renewables. The automobile industry is, of course, also involved in this metamorphosis – in addition to the introduction of vehicles with new power trains, the supply of the appropriate fuels for them is of vital importance. Recently at Empa representatives from the political and financial fields, as well as the automobile industry and various areas of research showed how these challenges might be tackled

Technology Briefing on "Critical Materials"23 February 2015
Are we independent of rare metals?

Numerous metallic elements are regarded as "critical": on one hand, they play an ever more important role in so-called future technologies and on the other, there is a high risk of supply bottlenecks. Small and medium-sized companies are also affected by this, and they are often not sure which of these materials they are dependent on. At a "Technology Briefing" at Empa, strategies for the sustainable use of critical materials were presented and discussed.
