Watching magnetic nano ‘tornadoes’ in 3D

The team, from the Universities of Cambridge and Glasgow in the UK and ETH Zurich and the Paul Scherrer Institute in Switzerland, used their technique to observe how the magnetisation behaves, the first time this has been done in three dimensions. The technique, called time-resolved magnetic laminography, could be used to understand and control the … Read more Watching magnetic nano ‘tornadoes’ in 3D

Fast-charging, long-running, bendy energy storage breakthrough

While at the proof-of-concept stage, it shows enormous potential as a portable power supply in several practical applications including electric vehicles, phones and wearable technology. The discovery, published today in Nature Energy, overcomes the issue faced by high-powered, fast-charging supercapacitors – that they usually cannot hold a large amount of energy in a small space. First … Read more Fast-charging, long-running, bendy energy storage breakthrough

Fragile topology: Two new studies explain the strange electron flow in future materials

Electrons race along the surface of certain unusual crystalline materials, except that sometimes they don’t. Two new studies from Princeton researchers and their collaborators explain the source of the surprising behavior and chart a course for restoring conductivity in these remarkable crystals, prized for their potential use in future technologies including quantum computers. The studies … Read more Fragile topology: Two new studies explain the strange electron flow in future materials

New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs

Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based energy generator (DEG), featured with a field-effect transistor (FET)-like structure that allows for high energy-conversion efficiency and instantaneous power density increased by thousands times compared to its counterparts … Read more New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs

Quantum fluctuations stabilize high-temperature superconductors

An international team of researchers from Spain, Italy, France, Germany, and Japan show that the crystal structure of the record superconducting LaH10 compound is stabilized by nuclear quantum fluctuations. Their result suggests that superconductivity approaching room temperature may be possible in hydrogen-rich compounds at much lower pressures than previously expected. The results are published today … Read more Quantum fluctuations stabilize high-temperature superconductors

Sand dunes can ‘communicate’ with each other

Even though they are inanimate objects, sand dunes can ‘communicate’ with each other. A team from the University of Cambridge has found that as they move, sand dunes interact with and repel their downstream neighbours. Using an experimental dune ‘racetrack’, the researchers observed that two identical dunes start out close together, but over time they … Read more Sand dunes can ‘communicate’ with each other

Making light work

A collaboration between McMaster and Harvard researchers has generated a new platform in which light beams communicate with one another through solid matter, establishing the foundation to explore a new form of computing. Their work is described in a paper published today in the Proceedings of the National Academy of Sciences. Kalaichelvi Saravanamuttu, an associate professor … Read more Making light work

Protective clothing with built-in sensors warns firefighters of too much heat

Imec, Ghent University, Brigade de Sapeurs-Pompiers de Paris, Connect Group and Sioen, today presented a prototype of new protective firefighters’ clothing with integrated temperature sensors and electronics to warn firefighters of too high ambient temperatures. The new protective sensing suit, that was developed within the framework of the Flemish I-CART project, was successfully tested at … Read more Protective clothing with built-in sensors warns firefighters of too much heat

UChicago physicists discover hidden symmetries, opening new avenues for material design

When you knock on a melon to see if it’s ripe, you are using sound waves to probe the structure of the material inside. Physicists at the University of Chicago were using the same concept to explore how sound waves travel through patterned structures when they noticed an oddity: completely different structures sounded the same. … Read more UChicago physicists discover hidden symmetries, opening new avenues for material design

Color-changing bandages sense and treat bacterial infections

According to the World Health Organization, antibiotic resistance is one of the biggest threats to global health. Sensing and treating bacterial infections earlier could help improve patients’ recovery, as well curb the spread of antibiotic-resistant microbes. Now, researchers reporting in ACS Central Science have developed color-changing bandages that can sense drug-resistant and drug-sensitive bacteria in wounds and … Read more Color-changing bandages sense and treat bacterial infections
