Researchers invent broad-band tunable terahertz absorber

Recently, a research team led by Prof. SHENG Zhigao from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science (HFIPS), along with collaborators in HFIPS and ShanghaiTech University, invented a broad-band ...

Using strain to control oxynitride properties

Japanese scientists have stumbled onto a simple method for controlling the introduction of defects, called 'vacancy layers," into perovskite oxynitrides, leading to changes in their physical properties. The approach, published ...

Light-controlled nanomachine controls catalysis

The vision of the future of miniaturization has produced a series of synthetic molecular motors that are driven by a range of energy sources and can carry out various movements. A research group at Friedrich-Alexander-Universität ...

Science reveals secrets of a mummy's portrait

How much information can you get from a speck of purple pigment, no bigger than the diameter of a hair, plucked from an Egyptian portrait that's nearly 2,000 years old? Plenty, according to a new study. Analysis of that speck ...

New tool to combat terrorism

Forensic science experts at Flinders University are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport.

Convenient antioxidant capacity measurement of food

Researchers from Kumamoto University (Japan) have developed a system to quickly and easily measure the antioxidant capacity of food. The new electrochemical system uses a gel form—bicontinuous microemulsion (BME), a mixture ...

Sorting out viruses with machine learning

The ongoing global pandemic has created an urgent need for rapid tests that can diagnose the presence of the SARS-CoV-2 virus, the pathogen that causes COVID-19, and distinguish it from other respiratory viruses. Now, researchers ...

AI-powered 'electronic nose' to sniff out meat freshness

A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has invented an artificial olfactory system that mimics the mammalian nose to assess the freshness of meat accurately.

Shining a light on the issue of wine fraud

University of Adelaide wine researchers are developing a fast and simple method of authenticating wine—a potential solution against the estimated billions of dollars' worth of wine fraud globally, but also offering a possible ...

Scientists find harmful chemicals in household dust

Since the 1970s, chemicals called brominated flame retardants (BFRs) have been added to a host of consumer and household products, ranging from electronics and mattresses to upholstery and carpets. While they were intended ...
