Researchers from Linköping University and the Royal Institute of Technology in Sweden propose a new device concept that can efficiently transfer the information carried by electron spin to light at room temperature - a stepping stone towards future information technology. They present their approach in an article in Nature Communications. In today's information technology, light and electron charge are the main media for information processing and transfer. In the search for information technology that is even faster, smaller and more energy-efficient, scientists around the globe are exploring another property of electrons - their spin. Electronics that exploit both the spin and the charge of the electron are called "spintronics". Just as the Earth spins around its own axis, an electron spins around its own axis, either clockwise or counterclockwise. The handedness of the rotation is referred to as spin-up and spin-down states. In spintronics, the two states represent the binary … [Read more...] about Nanoscale Pillars as a Building Block for Future Information Technology

Gains in energy and technology companies pushed U.S. stocks higher in afternoon trading Monday, adding to solid gains at the end of last week. Energy stocks got a boost from crude oil prices, which were trading above $70 a barrel for the first time since November 2014. Beverage makers and other consumer goods companies were among the laggards. Several corporate deals also helped lift the market.KEEPING SCORE: The S&P 500 index rose 13 points, or 0.5 percent, to 2,676 as of 1:40 p.m. Eastern Time. The Dow Jones industrial average gained 149 points, or 0.6 percent, to 24,412. The Nasdaq added 60 points, or 0.8 percent, to 7,270. The Russell 2000 index of smaller-company stocks picked up 16 points, or 1 percent, to 1,581.ENERGY: Oil futures rose to their highest level since November 2014 as a May 12 deadline approached for the U.S. to certify the nuclear agreement with Iran. Benchmark U.S. crude rose 86 cents, or 1.2 percent, to $70.58 a barrel in New York. Brent crude, the … [Read more...] about Energy, technology companies help lift US stock indexes
The bulk of the energy technology exports went to Germany. Photo: Colourbox Danish companies that produce energy technology exported 10.7 percent more in 2014 than the year before, setting an all-time export record. A report on last year’s export figures released by the Ministry of Climate on Thursday showed that energy technology exports hit their highest-ever level, accounting for a total of 74.4 billion kroner. The energy technology exports increased by 10.7 percent over 2013 levels at a time when Denmark’s overall exports grew by just 0.6 percent. According to the report, green technology accounted for the lion’s share of the total energy tech boom. Green energy exports grew by 15.4 percent in 2014 and totaled 43.6 billion kroner. “Demand for green solutions from Denmark increases every year. Our ambitious climate policy has contributed to ensuring that Danish businesses are in a strong position – and we need to fight to … [Read more...] about Denmark’s green energy exports set record
DONG's Avedøre Power Plant. Photo: DONG Energy A/S If Denmark is to hit its ambitious climate goals, DONG Energy will have to lead the way. The Local interviewed the primarily state-owned company's head of regulatory affairs about its transition to new energy sources, subsidies and the controversial sale of a 18 percent stake to Goldman Sachs that imploded the Danish government coalition. Danish Oil & Natural Gas (DONG) was established in 1972 to manage gas and oil resources in the Danish North Sea. In 2006 it merged with several electricity producers and distributors to become DONG Energy, Denmark's largest energy company. Since then, DONG Energy has proven itself a global leader in the fields of wind and biomass resources. Ulrik Stridbæk (pictured), the head of regulatory affairs at DONG Energy, discusses the strategic role of his company and the future of renewable energies. Could we start by discussing where Denmark’s renewable energy program is today? … [Read more...] about DONG powers Denmark’s renewable energy future
A variety of models predict the role renewables will play in 2050, but some may be over-optimistic, and should be used with caution, say researchers. The proportion of UK energy supplied by renewable energies is increasing every year; in 2017 wind, solar, biomass and hydroelectricity produced as much energy as was needed to power the whole of Britain in 1958. However, how much the proportion will rise by 2050 is an area of great debate. Now, researchers at Imperial College London have urged caution when basing future energy decisions on over-optimistic models that predict that the entire system could be run on renewables by the middle of this century. Mathematical models are used to provide future estimates by taking into account factors such as the development and adoption of new technologies to predict how much of our energy demand can be met by certain energy mixes in 2050. These models can then be used to produce 'pathways' that should ensure these targets are met - such as through … [Read more...] about Running on Renewables: How Sure Can we be About the Future?
