MIT students fortify concrete by adding recycled plastic

16/11/2017

MIT undergraduate students have found that, by exposing plastic flakes to small, harmless doses of gamma radiation, then pulverizing the flakes into a fine powder, they can mix the plastic with cement paste to produce concrete that is up to 20 percent stronger than conventional concrete.

A polymer 'love hormone' sensor for the early detection of autism

16/11/2017

Is it going to be possible to detect features of autism at birth? At the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw a sensor has come into being that means this may become a reality. The main recognition component of the new device is a polymer layer with a carefully designed structure. It recognizes molecules of oxytocin, a compound considered to be one of the ...

Alloys from the laser printer

15/11/2017

In the future, new designer alloys for aerospace applications can be manufactured using the 3-D laser melting process (Additive Manufacturing). Pioneering work in this field was provided by Empa researcher Christoph Kenel, who works today at Northwestern University (Chicago). Empa grants him the Research Award 2017.

Essential quantum computer component downsized by two orders of magnitude

14/11/2017

Researchers at IST Austria have built compact photon directional devices. Their micrometer-scale, nonmagnetic devices route microwave photons and can shield qubits from harmful noise. Qubits, or quantum bits, are the key building blocks that lie at the heart of every quantum computer. In order ...

Nanodiamonds show promise for aiding recovery from root canal

14/11/2017

People who undergo root canals may soon have a tiny but powerful ally that could prevent infection after treatment. In a paper published Oct. 23 in Proceedings of the National Academy of Sciences, UCLA researchers write that combining nanodiamonds with gutta percha, a material used to fill disinfected root canals, may enhance the gutta percha's protective properties.

Taming 'wild' electrons in graphene

13/11/2017

Graphene -- a one-atom-thick layer of the stuff in pencils -- is a better conductor than copper and is very promising for electronic devices, but with one catch: Electrons that move through it can't be stopped. Until now, that is. Scientists at Rutgers University-New Brunswick have learned how to tame the unruly electrons in graphene, paving the way for the ultra-fast transport of electrons ...

Transparent solar technology represents 'wave of the future'

10/11/2017

See-through solar materials that can be applied to windows represent a massive source of untapped energy and could harvest as much power as bigger, bulkier rooftop solar units, scientists report today in Nature Energy.

Solution to mysterious behavior of supercooled water

10/11/2017

Japan-based researchers developed a model to explain mysterious breakdown of Stokes-Einstein relationship in supercooled water. They revealed that intermittent hydrogen bond breakage between water molecules led to non-conformity with the Stokes-Einstein relationship.
