Gold in limbo between solid and melted states
If you heat a solid material enough, the thermal energy (latent heat) causes the material's molecules begin to break apart, forming a liquid. One of the most familiar examples of...
Epoxy resins: Hardening at the push of a button
Within seconds the new material can be completely transformed. Initially, the material is transparent and either in liquid or paste form; then, when any part of it is irradiated with...
Carbon chains adopt fusilli or spaghetti shapes if they have odd or even numbers
Helical shapes are very familiar in the natural world and, at the molecular level, of DNA, the very blueprint of life itself.
The magnet that didn't exist
In 1966, Japanese physicist Yosuke Nagaoka predicted the existence of a rather striking phenomenon: Nagaoka's ferromagnetism. His rigorous theory explains how materials can become magnetic, with one caveat: the specific...
Biometric devices help pinpoint factory workers' emotions and productivity
Happiness, as measured by a wearable biometric device, was closely related to productivity among a group of factory workers, reveals a recent study.
Biometric devices help pinpoint factory workers' emotions and productivity
Happiness, as measured by a wearable biometric device, was closely related to productivity among a group of factory workers in Laos, reveals a recent study.

Mysterious 'antihydrogen' particles reveal uncanny quantum effect
The bubbling, raucous quantum vacuum distorts the shape of every hydrogen atom in the universe, and it distorts antimatter "antihydrogen" too.
A fast, ecofriendly way of de-icing aircrafts
Ice on an aircraft's surfaces can be a hazard. It increases drag and fuel consumption, disrupts aerodynamic flows, and decreases lift—which impairs the aircraft's ability to fly safely. Researchers at...
Intelligently recovering and recycling balsa wood
There are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will...
Scientists expand memory effect range through spatial filtering
Speckle autocorrelation imaging is a new emergent imaging technique through scattering media, with its main advantages in simple experimental setup, single-shot fast detection and non-invasion. The prerequisite of speckle autocorrelation...
Measuring electron spin qubit without demolishing it
A group of scientists from the RIKEN Center for Emergent Matter Science in Japan have succeeded in taking repeated measurements of the spin of an electron in a silicon quantum...
Researchers from Chalmers University of Technology, Sweden, have made...
Researchers from Chalmers University of Technology, Sweden, have made a new contribution to the ongoing search into the possibility of life on Titan, Saturn’s largest moon. Using quantum mechanical calculations,...
Why is an empty shampoo bottle so easy to knock over?
It becomes annoyingly easy to knock over a shampoo bottle when it’s nearly empty. This is an easily observed and curiosity-provoking phenomenon that, according to Lehigh University physics professor Jerome Licini,...
A novel biofuel system for hydrogen production from biomass
A novel technology has been developed for hydrogen production from the process, which involves electron that is produced during the decomposition of biomass such as waste wood. The result produced...
Researchers develop photostimulated transparent glass ceramic
Magnetic data storage has been gradually replaced by optical data storage (ODS) with higher efficiency, lower energy consumption, larger capacity, and longer service lifetime. As a classical kind of ODS...
Proton solid oxide electrolytic cell facilitates non-oxidized dehydrogenation of ethane
Ethylene is an important petrochemical raw material. Its output is a symbol of a country's petrochemical production capacity and level. Due to the oxidation and dehydrogenation of ethane, it is...
A new strategy to stabilize carbon nitride photocatalyst for nitrogen reduction
Researchers from the Institute of Solid State Physics, Hefei Institutes of Physical Science developed a boron doped carbon nitride nanosheets with B-N-C coordination to stabilize surface exposed active nitrogen atoms...
Watch: 'Artemis Fowl': Colin Farrell goes missing in new trailer
Colin Farrell joins the cast of "Artemis Fowl" in the latest trailer for Disney's upcoming fantasy-adventure film.
Scientists pair machine learning with tomography to learn about material interfaces
By using machine learning as an image processing technique, scientists can dramatically accelerate the heretofore laborious manual process of quantitatively looking for and at interfaces without having to sacrifice accuracy.
Chris Hall: Can net-zero and the energy sector co-exist?
Deputy Prime Minister Chrystia Freeland insists a robust climate change plan can live alongside a thriving energy sector. But while the debate has become mired in blame-tossing, businesses are calling...
Scientists measure electron spin qubit without demolishing it
A group of scientists from the RIKEN Center for Emergent Matter Science in Japan has succeeded in taking repeated measurements of the spin of an electron in a silicon quantum dot (QD)...

Evaporating mixtures of two liquids create hypnotic designs
When liquids containing small particles evaporate, those fluids often leave behind fingerprints like coffee rings or whiskey webs (SN: 10/31/19). But liquids mixed with other liquids leave their own distinct residue patterns. An...
Olga Malinkiewicz wants to make good on the promise of perovskites
Her company, Saule Technologies, has a low-cost process to print the solar cells on a multitude of materials
Amy Prieto is building safer, more powerful batteries
With Prieto Battery, the Colorado State professor has redesigned the lithium-ion battery from the bottom up
Cristina Sáenz de Pipaón wants to put CO2 to good use
Her company, Orchestra Scientific, is developing membrane technology to separate carbon dioxide from other gases and use it as a product
Unique material could unlock new functionality in semiconductors
Researchers detailed how they designed and synthesized a unique material with controllable capabilities that make it very promising for future electronics.
