Backache – a matter of mechanics

Thanks to a collaboration with the Balgrist University Hospital and University of Pittsburgh, Empa is beginning to decode the mechanics of the lower vertebrae. Researchers would like be able to reveal how wear and tear comes about on vertebral bodies and spinal disks. This would also make choosing the appropriate therapy much easier.

Backache – a matter of mechanics

Some say that back pain is the price we pay for walking upright. Others claim that the problem only really started when humankind sat down to reflect and contemplate. Thanks to a collaboration with the University of Pittsburgh and Balgrist University Hospital, Empa is beginning to decode the mechanics of the lower vertebrae. Researchers soon will be able to reveal how wear and tear comes about on vertebral bodies and spinal disks. This will make choosing the appropriate therapy much easier.

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.
