A webGF-Mill image showing the motion of rocks and steel balls in a section along the length of a grinding mill. Particle colouring indicates particle speed with red being the fastest moving particles and blue the slowest or stationary particles.
CSIRO has developed an Internet-based simulation tool that predicts the motion of particles inside grinding mills, providing insight into the way mills work and enabling huge energy savings from smarter, more energy efficient design.
webGF-Mill assesses the design and function of the grinding mills used at mines to crush ore.
"Improving mill design is important because of the amount of energy that mills use," says CSIRO mathematician Dave Morton. "Typically, grinding mills are very inefficient. An average mill around 10 metres in diameter consumes roughly the energy required to supply 10 000 average Australian households. Unfortunately, only 5% of this energy is consumed by the processes that actually break the rocks inside the mill."

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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
