Special coating protects steel from hydrogen ‘attack’

Almost no evidence of brittleness

29-Jul-2020

Regeneratively produced hydrogen is an ideal energy carrier, which will be used in future applications as fuel cells and cars and will supplement natural gas as an energy source. But atomic hydrogen often induces brittle behavior in metals at high temperatures. Lukas Gröner of the Fraunhofer IWM, ...

Biofuel for ships

Diesel and gasoline sourced from renewables produces a lot less greenhouse gas

07-May-2020

The combustion of conventional fossil fuels accounts for a large share of global CO2 emissions. A great deal of criticism is levelled against cruise and merchant ships for polluting the environment with sooty waste gas and toxic heavy fuels. Researchers at the Fraunhofer Institute for ...

Characterizing and designing lubricants on the computer

Computational models based on molecular structure properties

15-Apr-2020

Lubricated shafts, bearings and gears only run 'like clockwork' when the components slide on a perfect lubricating film, generating as little friction, wear and energy loss as possible. To achieve this, engineers need to know the behavior of the lubricant film in the so-called tribo-contact, ...

Polyamides from terpenes

New biobased class of polyamides

11-Oct-2019

The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB has developed a sustainable alternative to petrochemically produced plastics using terpenes found in resin-rich wood. The natural substances are available from conifers such as pine, larch or spruce. In the production of ...
