A new type of laminate performed spectacularly in depth-of-penetration ballistics tests, but its greatest potential may derive from its ability to be tailored to meet specific engineering requirements
An engineering professor at the University of California, San Diego has described in the March issue of JOM (the Journal of the Minerals, Metals and Materials Society) the unique properties of a new type of metallic laminate that can serve as armor and as a replacement for beryllium, a strong but toxic metal commonly used in demanding aerospace applications.
"The new material we developed is environmentally safe, and while its stiffness equals that of steel, its only half as dense," said Kenneth S. Vecchio, author of the paper and a professor of mechanical and aerospace engineering in UCSDs Jacobs School of Engineering. "It performs spectacularly in our depth-of-penetration ballistics tests, but we think its greatest potential may derive from its unique ability to have its structure and properties tailored to meet a wide variety of application-specific engineering requirements."

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
