A research team from the Public University of Navarra has started a study of the design and development of absorbent materials that enable the storage of hydrogen, a clean fuel that can be used as an alternative to those derived from fossil fuels, such as petrol and diesel. The storage of this element is, in fact, a key process in the change over from internal combustion engines – contaminating and not very efficient, to cars with hydrogen fuel cells.
The project, entitled, Development of materials for storage of hydrogen by means of physical adsorption.
At present, hydrogen production “is not a problem”. For some years now, hydrogen has been obtained by means of catalytic reforming or by the electrolysis of water. However, the question hanging over the use of hydrogen as a fuel is its generation or storage in the quantities required for a means of transport and without it being dangerous – as we are dealing with a highly inflammable gas. Under normal conditions hydrogen is in a gaseous state and thus has to be kept under high pressure or, if we wish to reduce the pressure, the storage temperature has to be lowered. These two circumstances give rise to technological difficulties, apart from the added safety ones.

Artificial agent designs quantum experiments
19.01.2018 | Universität Innsbruck
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
