Laser pulses capture unexplored polaronic states

In an international experiment, researchers observed Jahn–Teller polarons—quasiparticles that could play an important role in future ultrafast spintronic devices. These polarons emerged within the crystal lattice of cobalt oxide that had been activated by carefully tailored laser

Inorganic nanoscale device behaves like a single neuron, opening doors for AI and retinal

McGill University researchers have developed a light-detecting nanoscale structure that mimics how a neuron processes information. The neuron-like behavior emerges from the materials themselves, reducing the energy demand associated with similar devices that rely on circuits or s

Nanopattern method unlocks precise control of disorder for wave-guiding devices

A research team has developed a methodology to precisely design and control the "degree of disorder" in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films. The work was led by Professor So Youn Kim of the Seoul National University College of Engineering D

Switching spin states in manganese ions with light opens new path for molecular memory

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular materials, which require very low temperatures—ran

NASA tests new refuel device for future in-space refueling missions

For NASA's next generation of deep-space exploration missions, spacecraft may need to refuel in Earth orbit before pushing farther into the solar system. Similar to how a gas pump needs a nozzle to fit your fuel tank, future spacecraft could require a special device in order to f

Darwin residents want answers on toxic gas emissions: Science shows their concerns are war

For years, Darwin residents have been concerned about toxic chemicals emitted by the city's two gas export facilities. In fact, some locals are so worried about these airborne chemicals—particularly benzene—they recently formed a community group and launched a fundraiser to buy a

400-year-old painting reveals a bat's secret diet

Natural historians have many observational techniques in their toolkit for learning about the natural world: tagging animals with tracking devices, recording sounds, analyzing droppings or simply watching and counting. As technology has advanced, these methods have grown far more

Acceptor molecule upconverts low-energy green light to high-energy purple with high effici

Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply pass through the material without being used as energy

Scientists create quantum sound device that could transform communications

A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures. The surprising behavior pushes beyond the limits predicted by current theories, suggesting scientis

Plug-and-play single-photon source can work at room temperature

The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play system that works as soon as it is powered on,
