Engineers in Nottingham are developing ultra-clean coal that could make power generation 50% more efficient and reduce carbon dioxide emissions by a third. A team at The University of Nottingham is one of only two in the world working on ground-breaking techniques to purify one of the world’s main energy sources.
They have been awarded £120,000 to help them develop the ultra-clean fuel for the power stations of the future. Dr Karen Steel, of the School of Chemical, Environmental and Mining Engineering, said: “Ultra-clean coal is seen as something of a Holy Grail in energy generation. “It’s a very efficient way of producing electricity, and it’s also much less harmful for the environment. This is an exciting project in the sense that ultra-clean coal has world-wide applicability.”
When coal is dug from the ground, it contains about 15% mineral matter — including sulphates, oxides, clays, quartz and carbonates — which greatly restricts its use. A chemical leaching process being developed by Dr Steel and her team promises to reduce this figure to less than 0.1% — meaning much greater efficiency per tonne of coal and up to 33% less carbon dioxide (CO2) pollution from the power station. CO2 emissions are implicated in global warming. Currently almost a third of such emissions in the UK come from power stations.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
