Scientists have made a world-first discovery which is a step towards using environmentally-friendly hydrogen to power our cars.
A team from the Universities of Newcastle upon Tyne and Liverpool in the UK, who report their findings in the prestigious academic journal, Science, have found a safe way of storing and releasing hydrogen to produce energy. They do this using nanoporous materials, which have tiny pores that are one hundred-thousandth (100,00th) the thickness of a sheet of paper.
Hydrogen has been investigated for a long time as a replacement for petrol, amid worries over the long-term availability of fossil fuels. It is also an environmentally-friendly alternative, as it produces only water rather than the ‘greenhouse gas’, carbon dioxide. However, scientists and others have been baffled for a long time about how to store the substance – which is a gas and so contains less energy in a given volume than the liquid petrol - safely and efficiently.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
