WiFi capacity doubled at less than half the size
New York NY (SPX) Apr 22, 2016 -
Last year, Columbia Engineering researchers were the first to invent a technology - full-duplex radio integrated circuits (ICs) - that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio.
That system required two antennas, one for the transmitter and one for the receiver. And now the team, led by Electrical Engine ...

Ultra-long, one-dimensional carbon chains are synthesised for the first time
Barrio Sarriena, Spain (SPX) Apr 22, 2016 -
Elemental carbon appears in many different forms, some of which are very well-known and have been thoroughly studied: diamond, graphite, graphene, fullerenes, nanotubes and carbyne. Within this "carbon family", carbyne (a truly one-dimensional carbon structure) is the only one that has not been synthesised until now, despite having been studied for more than 50 years. Organic chemists across the ...

Innovative Exeter research pioneers nanotechnology for gas sensing
Exeter, UK (SPX) Apr 22, 2016 -
A team of scientists from the University of Exeter have created a new type of device that could be used to develop cost-effective gas sensors. The pioneering team, which includes two second year Exeter undergraduates, have created a new type of device that emits light in the infrared part of the spectrum. Many important gases strongly absorb infrared light and this characteristic absorption can ...

Generation of tailored magnetic materials
Geneva, Switzerland (SPX) Apr 22, 2016 -
Every day, new technologies require more precision in the intrinsic properties of the materials used. To meet increasingly specific requirements, physicists are interested in a generation of artificial materials, the properties of which can be controlled.
Researchers at the University of Geneva (UNIGE), Switzerland, in collaboration with French and English teams, have succeed in manipulati ...

Global leaders agree to set price on carbon pollution
Washington (AFP) April 21, 2016 -
Six world leaders and the heads of powerful multilateral organizations agreed Thursday to push for broader implementation of carbon pricing schemes to accelerate the fight against global warming.
The leaders of Canada, Germany, France, Mexico, Ethiopia and Chile, along with the IMF, World Bank, and OECD, pressed for the use of carbon pricing to cover 25 percent of global emissions within fou ...

Using methane rather than flaring it
Zurich, Switzerland (SPX) Apr 22, 2016 -
Methane is an abundant and inexpensive gas. Although it would be a suitable energy source and base material for the chemical industry, huge quantities of it are simply burnt off around the world - above all at oil fields and refineries. "On satellite images of Earth at night, the Middle East is brightly illuminated.
This is not because the region has an especially high number of large, bri ...

Fossil fuels could be phased out worldwide in a decade
Sussex, UK (SPX) Apr 22, 2016 -
The worldwide reliance on burning fossil fuels to create energy could be phased out in a decade, according to an article published by a major energy think tank in the UK. Professor Benjamin Sovacool, Director of the Sussex Energy Group at the University of Sussex, believes that the next great energy revolution could take place in a fraction of the time of major changes in the past.
But it ...
