Researchers at the University of Warwick’s Warwick Process Technology Group have devised a process that turns wet waste from sewage farms and paper mills into a source of power.
University of Warwick researcher Dr Ashok Bhattacharya and his team are part of a Europe wide consortium that have cracked the problem of how to extract very pure levels of hydrogen from wet bio-matter, such as sewage or paper mill waste. This very pure hydrogen can then be used in “fuel cells” to power homes, factories and cars. The research consortium have now received £2.5million in European funding to work up their lab based solution into larger prototypes. Eventually the research team’s “plated membrane reactors” could be built as small industrial units, no bigger than a large room in some cases, and added directly to the sites of sewage plants or paper mills.
Previous attempts to extract pure hydrogen from bio-matter to power fuel cells have only met with limited success, even with dry material. The new process extracts very pure hydrogen from the more difficult but exceedingly abundant wet bio-matter and even makes a virtue of the water content of the material to generate even more pure hydrogen.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
