New technology for producing porous aluminum

A new technology of producing an unsinkable aluminum alloy was developed at Peter the Great St. Petersburg Polytechnic University (SPbPU). Porosity is produced by the addition of foaming gas into liquid aluminum during re-melting. ...

Capacitor withstands temperatures of up to 300 degrees Celsius

Heat, dust and moisture damage electronic components. Protecting against dust and moisture is fairly straightforward, but heat remains a problem because it is created within the component itself. Anywhere electricity flows, ...

Artificial intelligence helps in the discovery of new materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to ...

Recycling permanent magnets in one go

Electric motors or wind turbines are driven by powerful permanent magnets. The most powerful ones are based on the rare earth elements neodymium and dysprosium. In future, a new process route realized by Fraunhofer researchers ...

Record high pressure squeezes secrets out of osmium

An international team of scientists led by the University of Bayreuth and with participation of DESY has created the highest static pressure ever achieved in a lab: Using a special high pressure device, the researchers investigated ...

New family of tiny crystals glow bright in LED lights

(Phys.org) —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.

Naturally occurring mineral for thermoelectric power generation

Researchers with the National Institute of Advanced Industrial Science and Technology have confirmed that a naturally occurring mineral, tetrahedrite, which mainly consists of non-toxic and earth-abundant elements, copper ...
