Researchers have developed an optical switch that routes light from one computer chip to another in just 20 billionths of a second -- faster than any other similar device. The compact switch is the first to operate at voltages low enough to be integrated onto low-cost silicon chips and redirects light with very low signal loss.
New research by engineers combines atomic-scale experimentation with computer modeling to determine how much energy it takes to bend multilayer graphene -- a question that has eluded scientists since graphene was first isolated.
Old books give off a complex mélange of odors, ranging from pleasant (almonds, caramel and chocolate) to nasty (formaldehyde, old clothes and trash). Detecting early signs of paper degradation could help guide preservation efforts, but most techniques destroy the very paper historians want to save. Now, researchers have developed an electronic nose that can non-destructively sniff out odors emitted by books of different paper compositions, conditions and ages.
Scalable 2D-type MoO3 nanosheets were synthesized via van der Waal epitaxy growth method. Its electrical and mechanical properties of MoO3 nanosheets are maintained even at a few layer level and the thickness sensitivity is small compared to other 2D materials.
Researchers have developed equations for quantifying electromagnetic interference (EM noise) and elucidated its origin, allowing for the best circuit configuration to reduce EM noise.
To seamlessly integrate electronics with the natural world, materials are needed that are both stretchable and degradable -- for example, flexible medical devices that conform to the surfaces of internal organs, but that dissolve and disappear when no longer needed. However, introducing these properties to electronics has been challenging. Now, researchers have developed stretchable, degradable semiconductors that could someday find applications in health and environmental monitoring.
An Australian study revealing new spin textures in pyrite could unlock these materials' potential in future spintronics devices. The study of pyrite-type materials provides new insights and opportunities for selective spin control in topological spintronics devices.
Using a special type of two-dimensional material, researchers have developed a new way to make light sensors that improves their sensitivity and could allow manufacturers to keep up with the growing demand for their use in devices ranging from television remotes to fiber optic receivers in data centers, and light detecting and ranging systems (LiDAR) in autonomous vehicles.
Researchers have shown for the first time that it is possible to print complete integrated circuits with more than 100 organic electrochemical transistors.
Physicists demonstrate simultaneous control over transport and spin properties of cold atoms, and thus establish a framework for exploring concepts in spintronics and solid-state physics.
Engineers have embedded high performance electrical circuits inside 3D-printed plastics, which could lead to smaller and versatile drones and better-performing small satellites, biomedical implants and smart structures. They used pulses of high-energy light to fuse tiny silver wires, resulting in circuits that conduct 10 times more electricity than the state of the art, according to a new study.
Next-generation batteries will probably see the replacement of lithium ions by more abundant and environmentally benign alkali metal or multivalent ions. A major challenge, however, is the development of stable electrodes that combine high energy densities with fast charge and discharge rates. Scientists now report a high-performance cathode made of an organic polymer to be used in low-cost, environmentally benign, and durable sodium-ion batteries.
