A new way to achieve integrated photonics — a new device has been developed that could have applications in imaging, sensing and quantum information processing, such as on-chip transformation optics, mathematical operations and spectrometers.
Read moreA group of researchers developed a highly sensitive rectifying element in the form of a nanowire backward diode, which can covert low-power microwaves into electricity. The new technology is expected that the newly-developed nanowire backward diode will be applied in using plentiful ambient radio wave energy in 5G communications, serving as a stable power source of sensors and contributing to battery-free sensors.
Read moreFor the first time researchers successfully used laser pulses to excite an iron-based compound into a superconducting state. This means it conducted electricity without resistance. The iron compound is a known superconductor at ultralow temperatures, but this method enables superconduction at higher temperatures. It is hoped this kind of research could greatly improve power efficiency in electrical equipment and electronic devices.
Read moreResearchers have developed a type of processor called PAXEL, a device that can potentially bypass Moore's Law and increase the speed and efficiency of computing. Researchers looked at using light for the data transport step in integrated circuits, since photons are not subject to Moore's Law. Instead of integrated electronic circuits, much new development now involves photonic integrated circuits. The PAXEL accelerator takes this approach and uses power-efficient nanophotonics.
Read moreA team of researchers has used stretchable materials to develop a battery that can be bent, stretched and twisted. For applications in bendable electronic devices, this is precisely the kind of battery they need.
Read moreDigital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find scientists.
Read moreResearchers have developed an electronic chip that can perform high-sensitivity intracellular recording from thousands of connected neurons simultaneously. This breakthrough allowed them to map synaptic connectivity at an unprecedented level, identifying hundreds of synaptic connections.
Read moreIdentifying geological features in a densely vegetated, steep, and rough terrain can be almost impossible. Imagery like LiDAR can help researchers see through the tree cover, but subtle landforms can often be missed by the human eye.
Read moreA new study shows that, contrary to widespread belief within the solar power industry, new kinds of solar cells and panels don't necessarily have to last for 25 to 30 years in order to be economically viable in today's market.
Read moreThis study aimed to propose a new method for a bi-objective optimization. Ten student participants used a touch screen at 3 different installation heights, 3 tilt angles and with 3 button sizes. The joint angles, while using a touch screen, were measured to estimate physical workload. With the subjective screen visibility determined, the Pareto optimal solution showed ranges of 1124-1251 mm height and 44.4-67.9° tilt angle for the optimal installation of touch screens.
