Study puts spin into quantum technologies

A team of international scientists investigating how to control the spin of atom-like impurities in 2D materials have observed the dependence of the atom’s energy on an external magnetic field for the first time. The results of the study, published in Nature Materials, will be of interest to both academic and industry research groups working on … Read more Study puts spin into quantum technologies

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

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

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

Detection of very high frequency magnetic resonance could revolutionize electronics

A team of physicists has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection equipment on microchips and enhance sensitivity. Terahertz is a unit of electromagnetic wave frequency: One gigahertz equals 1 billion hertz; 1 terahertz equals 1,000 gigahertz. The higher the … Read more Detection of very high frequency magnetic resonance could revolutionize electronics

UofT researchers find: Most engineered nanoparticles enter tumours through cells, not between them

The prevailing theory in cancer nanomedicine — an approach that enables more targeted therapies than standard chemotherapy — has been that nanoparticles mainly diffuse passively into tumours through tiny gaps between cells in the endothelium, which lines the inner wall of blood vessels that support tumour growth. The researchers previously showed that less than one per … Read more UofT researchers find: Most engineered nanoparticles enter tumours through cells, not between them

Tuning optical resonators gives researchers control over transparency

In the quantum realm, under some circumstances and with the right interference patterns, light can pass through opaque media. This feature of light is more than a mathematical trick; optical quantum memory, optical storage and other systems that depend on interactions of just a few photons at a time rely on the process, called electromagnetically … Read more Tuning optical resonators gives researchers control over transparency

Nano antennas for data transfer

Directional antennas convert electrical signals to radio waves and emit them in a particular direction, allowing increased performance and reduced interference. This principle, which is useful in radio wave technology, could also be interesting for miniaturised light sources. After all, almost all Internet-based communication utilises optical light communication. Directional antennas for light could be used … Read more Nano antennas for data transfer

Monash develops world’s most efficient lithium-sulfur battery

Imagine having access to a battery, which has the potential to power your phone for five continuous days, or enable an electric vehicle to drive more than 1000km without needing to “refuel”. Monash University researchers are on the brink of commercialising the world’s most efficient lithium-sulphur (Li-S) battery, which could outperform current market leaders by … Read more Monash develops world’s most efficient lithium-sulfur battery
