Current body armour relies on a stiff and relatively heavy layer of ceramic material to absorb ballistic impact. This makes body armour heavy and unwieldy.
The Daresbury team, together with researchers from Tuskegee and Florida Atlantic universities in the USA, are evaluating new nanocomposite materials which can be woven into fabrics to provide greater flexibility as well as better ballistic protection. They have found that incorporating spherical nanoparticles of silicon or titanium dioxide or carbon nanotubes in a plastic or epoxy matrix offers improved ballistic resistance together with greatly improved flexibility.
Daresbury Laboratory’s role has been to investigate ways to make the new materials as strong as possible. The manufacturing process used to make the new body armour can introduce impurities which limit the amount of nanoparticles that can be incorporated and so reduce its effectiveness.
Dr Vin Dhanak said, “We’re using the synchrotron light source, or SRS, and the photoelectron spectrometer at the National Centre for electron spectroscopy and surface analysis, both based at Daresbury. These world-leading instruments let us analyse how the nanoparticles bond with the matrix materials in which they’re embedded. This will help improve the manufacturing process to eliminate impurities and make the materials stronger.”

NASA keeps watch over space explosions

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
