The U.S. Navy needs lighter materials so ships will go further faster. One way to do that is to use new composite materials. But how will these materials respond to fire -- one of the most critical safety concerns on a ship? Virginia Tech material scientists have developed models to test composites for fire resistance – and have a recommendation.
John Bausano, a doctoral student in the chemistry-engineering interdisciplinary Macromolecular Science and Infrastructure Engineering program at Virginia Tech, will present his research in the Excellence in Graduate Polymer Science Research Symposium at the 231st American Chemical Society National Meeting in Atlanta on March 26-30.
Working with Jack Lesko, associate professor of engineering science and mechanics, Bausano developed a testing method – a one-sided heat flux test that can be used on a sample as small as one inch by six inches (1x6") to test a commercially available material – E-glass vinyl ester composite laminates. One side of the material is heated to simulate fire on one side of a wall. A load is placed on one edge to simulate a load-bearing wall. "We measure the deflection, failure, and how hot it gets on the cool side," said Bausano. "That is an important issue because you dont want the fire to spread."

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.
