Nano-sized silver particles open way to new breed of antimicrobial materials
Scientists can now incorporate silver particles into polypropylene to produce an anti-microbial material that could be used in anything from carpets, to napkins and surgical masks.
Silver has been medically proven to kill over 650 disease-causing organisms in the body and is also very safe. By combining silver and polypropylene to produce an organic-inorganic fibre, researchers have produced the first safe, anti-microbial fibre with a wide range of possible applications.
Polypropylene fibre is one of the most widely used synthetic fibres in the textile industry because it is cheaper and stronger than other synthetic fibres. Researchers have demonstrated, in a paper to be published in the July issue of Polymer International, available online in June, that they can produce two types of fibres both with silver particles distributed evenly along the length of the fibre.

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...
