Already the evidence is present for a revolution in the manufacture of materials based on nano-engineered structures. However, prior to these “nanomaterials” becoming dominant in the marketplace a precise understanding of how to tailor their properties for specific applications, coupled with cheap, reliable fabrication methods is required.
Scientists at the Advanced Technology Institute (ATI) of the University of Surrey and at the School of Chemistry in the University of Bristol have been awarded funding of nearly £0.87M from the Engineering and Physical Sciences Research Council (EPSRC) to investigate techniques using high-power, short-pulsed lasers for the production of important nanomaterials, including nanoclusters, nanotubes and nanorods of carbon and zinc oxide, with controllable electrical and optical properties. These techniques, including pulsed laser deposition and laser annealing, are ideal research tools for rapid investigation of a wide variety of synthesis environments, which should enable a plethora of new technologically significant nanomaterials. This project will be highly synergistic, addressing the full range of challenges, from obtaining a fundamental understanding of the growth processes to producing physical, chemical and biological sensors based on the products.The ATI’s Dr. Simon Henley, who will spearhead the research effort, said;
He added; “This collaboration brings together two groups with well-matched expertise in complementary areas. The group at Bristol specialises in obtaining a precise understanding of the chemistry occurring during laser synthesis, via optical and mass spectrometry, and the laser deposition research at the ATI focuses on producing nano-scale electronic and optical devices.”Prof. Mike Ashfold, lead researcher at Bristol commented;

Gravitational wave kicks monster black hole out of galactic core

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.
