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
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?
Whoever, or, rather, whichever team, as scientific discoveries today are rarely made by a single person, reinvents the battery, will become billionaire overnight is the common understanding of Wall Street analysts betting on breakthroughs in battery tech.It won't be long before everything - from our cell phones, through our cars, to our houses - uses some sort of electricity storage that ought to be cheaper and much more efficient than what we have now. The current Li-ion technology has been good to us, but is nearing its limits, with potential about 30% above current levels at the maximum, and that's that, say researchers.Still, we are on the cusp of battery technology breakthroughs that would allow our spec'd-out smartphones to last for days, our cars to drive 500+ miles on a charge, and our houses to store enough energy derived from solar panels or other sources to last days on end without resorting to the grid.That's why we are rounding up a few of these promising inventions that … [Read more...] about 5 future battery technologies to make your phone last longer and charge faster

Slammer (Posts: 1515; Member since: 03 Jun 2010) Who are we kidding here? The battery industry is no different than the oil industry. The goal will be to create a finite cap. There are many options in design and concept to increase usage on single charges, but sadly, most will not make it to the table with all the elements intact. The directive is to take these discoveries and design limitations so sales do not take a hit. posted on 20 Mar 2015, 14:11 3 4. Ashoaib (Posts: 3229; Member since: 15 Nov 2013) Well said.... same like some break through technologies in power generation were destroyed by governments/cooporates... even some of the inventors died in accidents or strange circumtances... Nicola Telsa's work was kept under the dust for ages and destroyed for unknown reasons, we … [Read more...] about Comments for : 5 future battery technologies to make your phone last longer and charge faster
