A Washington State University research team has uncovered significant and previously unknown vulnerabilities in high-performance computer chips that could lead to failures in modern electronics.
Millions of new memory cells could be part of a computer chip and save power for smart devices, thanks to the discovery of a previously unobserved functionality in a super thin material.
Ferroelectric HfO2-based transistor and memory are expected to realize ultralow power electronics; however, their operation mechanism and scalability were not clarified yet.?Physical mechanism of low voltage operation of a transistor with ferroelectric-HfO2 gate insulator has been experimentally clarified. Scalability of ferroelectric memory with HfO2 tunnel-layer down to 20nm diameter has been theoretically elucidated.?The obtained results will contribute to enabling ultralow power IoT device and thus highly sophisticated network services.
Challenge any modern human to go a day without a phone or computer, and you'd be hard pressed to get any takers. Our collective obsession with all things electronic is driving a dramatic daily drain on the world's power. In fact, according to studies from the Semiconductor Research Corporation, if we continue on pace with our current ever-increasing energy consumption, by the year 2035, we will use all of the world's energy to run our computers - an impossible/unsustainable situation.
Farmers can already use drones to soar over huge fields and monitor temperature, humidity or crop health. But these machines need so much power to fly that they can't get very far without needing a charge. Now, engineers at the University of Washington have created a sensing system that is small enough to ride aboard a bumblebee.
A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device which is able to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories. The novel spintronic memory device employs ferrimagnets and was developed in collaboration with researchers from Toyota Technological Institute, Nagoya, and Korea University, Seoul.
Scientists from Jülich together with colleagues from Aachen and Turin have produced a memristive element made from nanowires that functions in much the same way as a biological nerve cell. The component is able to both save and process information, as well as receive numerous signals in parallel. The resistive switching cell made from oxide crystal nanowires is thus proving to be the ideal candidate for use in building bioinspired 'neuromorphic' processors.
Researchers with the Department of Energy's Oak Ridge National Laboratory have demonstrated a new level of control over photons encoded with quantum information. The team's experimental system allows them to manipulate the frequency of photons to bring about superposition, a state that enables quantum operations and computing.
An international team of scientists demonstrates a new neurotechnology for reading out neural signals of position in real-time as rats run a maze, or replay it during sleep, with a high degree of accuracy, with more than 1,000 input channels, and the ability to account for the statistical relevance of the readings almost instantly after they are made.
While most large corporations take responsibility for occupational risks, many partake in transferring these risks to smaller companies and the informal sector, where health risks are unrecognized and under-reported. More than half of the workers in many developing economies work in the informal sector where there are few, or no, workplace health protections.
