DAC 2015 Day 2: Keynotes, Tutorials and More
By Brian Bailey - 09 Jun, 2015 - Comments: 0

Walking to DAC, you had to pass the Apple Developers Conference. The line to get in wrapped all the way around the block and there were many peaceful protests directed towards them. Large TV trucks, trucks from CNN, MSNBC and many others lined the streets to hear about new capabilities coming to the group of people who create the Apps for Apple devices. None of them were probably even aware tha... » read more

Hybrid supercapacitors Researchers at UCLA combined the best qualities of batteries and supercapacitors in a new 3-D hybrid supercapacitor. Based on laser-scribed graphene and manganese dioxide, the new component stores large amounts of energy, recharges quickly and can last for more than 10,000 recharge cycles. The team also created a microsupercapacitor small enough to fit in wearable o... » read more

Simulating ultrafast phenomena Interesting phenomena can happen when electronic states in materials are excited during dynamic processes. As an example, electrical charge transfer can take place on quadrillionth-of-a-second, or femtosecond, timescales. Numerical simulations in real-time provide the best way to study these processes. Such simulations, however, can be extremely expensive. R... » read more

Mapping temperature Given that overheating is a major problem for chips today a team of UCLA and USC scientists have made a breakthrough that they believe should enable engineers to design microprocessors that minimize that problem with a thermal imaging technique that can see how the temperature changes from point to point inside the smallest electronic circuits. The technique is called pl... » read more

Better photodetectors Photodetectors are semiconductor devices that convert incoming light into electrical signals used in a vast array of products, from visible and infrared light detection systems to television remote controls. Meanwhile, perovskite is an organic-inorganic hybrid material with a crystal structure that is very efficient at converting light into electricity, and in recent year... » read more

A majority of Americans cannot endure more than two hours without checking their electronic devices, according to new data released in the Crucial.com Tech-Life Balance Survey. One in four Americans becomes stressed by going longer than 30 minutes without checking their email or phone due to a fear of missing out. Additionally, one in five would sooner go to dinner with an ex significant other ... » read more

How transistors operate at absolute zero Research led by scientists at Chalmers University of Technology in Sweden and Caltech in California have demonstrated how noise in a microwave amplifier is limited by self-heating at very low temperatures, which is expected to be of importance for future discoveries in such as quantum computers and radio astronomy. The team also included researchers ... » read more

Simplified superconducting circuits Computer chips with superconducting circuits, which means they have no electrical resistance, are said to be 50 to 100 times as energy-efficient as today’s technology. Superconducting chips are also said to have greater processing power: Superconducting circuits that use so-called Josephson junctions have been clocked at 770 gigahertz, or 500 times the spe... » read more

Improved liquid battery Researchers at MIT, led by a materials chemistry professor, have improved a proposed liquid battery system that could enable renewable energy sources to compete with conventional power plants. Professor Donald Sadoway and some colleagues have already started a company to produce electrical-grid-scale liquid batteries, with layers of molten material that automatically... » read more
