In the article in C&EN's current edition, Senior Business Editor Melody M. Bomgardner explains that fracking or hydraulic fracturing involves pumping massive amounts of grainy substances, called proppants, down oil or natural gas wells.
Proppants enable production from rock formations 10,000 or 20,000 feet below the surface. To access the oil and gas in these deposits, they need to be fractured open with a mixture of fluid and proppants pumped down wells under high pressure. The grains literally prop up the fissures in these rocks so that oil and gas can flow to the surface.
The article describes development of a new genre of proppants to meet the needs of today's drillers. For wells that reach more than a mile down, drillers may need 10 million to 20 million pounds of proppants to get oil or natural gas flowing.
Drilling companies are going after more-difficult-to-access reserves of oil and gas that require tougher proppants. Some of the new materials, for instance, use high-tech ceramics like those used in aerospace and military applications or sand with each particle coated with curable resins.

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.
