Electronic devices such as mobile phones and tablets spur on a scientific race to find smaller and smaller information processing and storage elements. An international collaboration of scientists has been able to reproduce in particles measuring 10 to 20 nanometres a magnetic phenomenon of great importance in magnetic devices: the antiferromagnetic coupling between layers.
Andrea Alù, associate professor in the Department of Electrical and Computer Engineering at the Cockrell School of Engineering, and his team have proposed a design for an active cloak that draws energy from a battery, allowing objects to become undetectable to radio sensors over a greater range of frequencies.
Samsung Electronics Co. and LG Electronics Inc. said their curved TVs will get bigger and sport the sharpness four times the regular HD television sets. The world's two largest TV makers will display ultra-HD TVs with curved screens that measure 105 inches diagonally in Las Vegas next month, they said in separate statements Thursday.
It's fairly easy to pick a holiday present, stick a bow on it and say "enjoy" when you give it to someone. It's tougher to give a gift that keeps on giving and challenges the mind. Luckily, there are plenty of gift projects for "makers" — from robot kits to programmable microcontrollers to musical instruments. The time is right to give the gift of making.
Photos of the Day: York U molecular communication researchers send world's first text message using vodkaDecember 19, 2013 9:16 am | by EurekAlert! | News | Comments
After successfully text messaging 'O Canada' using evaporated vodka, two York University researchers and their UK-based counterpart say their simple system can be used where conventional wireless technology fails. The chemical signal, using the alcohol found in vodka in this case, was sent four metres across the lab....
We’re not talking about the seasoning, though I’d think more than just African economy would benefit if salt was still used as currency. SALT is an acronym for the South African Large Telescope — not the most creative name, but very simple and direct. Advancements in the field of astronomy are being seen in several different countries on the vast continent....
Highly integrated semiconductor products are not only a trend in consumer products, but also in motor-control applications. Concurrently, the share of Brushless DC (BLDC) motors is gradually increasing over other motor types in a number of markets, such as automotive and medical applications.
Leveraging advanced processor functionality to facilitate ease of design has been discussed throughout recent decades. Nowadays, even greater design flexibility allows engineers to use standard Model-Based design with MATLAB and Simulink can be used to optimize motor control systems functionality and to minimize overall design time.
Ulsan National Institute of Science and Technology announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field -effect transistor with semiconducting nature. This opens up opportunities for practical use in electronic devices.
Arc discharges are common in everyday conditions like welding or in lightning storms. But in altered gravity, not as much is known about the behaviour of electric discharges. For the first time, Jiří Šperka from Masaryk University, Czech Republic, and his Dutch colleagues studied the behaviour of a special type of arc discharge...
If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body. Researchers discovered a molecular “switch” in a receptor that controls cell behavior using detailed molecular dynamics simulations on a computer.
The lithium-ion batteries that power our laptops, smartphones and electric vehicles could have significantly higher energy density if their graphite anodes were to be replaced by lithium metal anodes. Hampering this change, however, has been the so-called dendrite problem.
The biggest Bitcoin exchange in China said Wednesday that it's no longer accepting yuan deposits, dealing another setback to the virtual currency. BTC China's announcement on its Twitter-like Sina Weibo account comes two weeks after China's central bank said the country's banks and payments systems were barred from handling the virtual currency.
Photos of the Day: Mass. high-tech startup launches device that transforms any bike into an electric-hybridDecember 18, 2013 8:50 am | by RODRIQUE NGOWI, Associated Press | News | Comments
A Massachusetts startup is launching a new device that transforms almost any bicycle into an electric-hybrid vehicle using an app on a smartphone. The device, called the Copenhagen Wheel, is installed as part of a rear hub of a bike wheel and is packed with a proprietary computer....
Years ago before Soldiers used cell phones and social media and when long-distance calling was expensive, they would often communicate from remote areas to home via MARSgrams and MARS telephone patches through the Military Auxiliary Radio System....
