New technique builds super-hard metals from nanoparticles

Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal's grain structure—the microscopic ...

Single atoms as a catalyst

For years, the metal nanoparticles used in catalysts have been getting smaller and smaller. Now, a research team at TU Wien in Vienna, Austria have shown that everything is suddenly different when you arrive at the smallest ...

Reducing traps increases performance of organic photodetectors

Physicists at the Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) discovered that trap states rule the performance of organic photodetectors, ultimately limiting their detectivity. These highly ...

Making masks smarter and safer against COVID-19

A new tool for monitoring COVID-19 may one day be right under your nose. Researchers at the University of California San Diego are developing a color-changing test strip that can be stuck on a mask and used to detect SARS-CoV-2 ...

Teamwork in a molecule

Chemists at the Friedrich Schiller University Jena have demonstrated the value of 'teamwork' by successfully harnessing the interaction between two gallium atoms in a novel compound to split the particularly strong bond between ...

New antifungal compound from ant farms

Attine ants are farmers, and they grow fungus as food. Pseudonocardia and Streptomyces bacteria are their farmhands, producing metabolites that protect the crop from pathogens. Surprisingly, these metabolites lack common ...

New metamaterial offers reprogrammable properties

Over the past 20 years, scientists have been developing metamaterials, or materials that don't occur naturally and whose mechanical properties result from their designed structure rather than their chemical composition. They ...

Researchers create new form of cultivated meat

McMaster researchers have developed a new form of cultivated meat using a method that promises more natural flavor and texture than other alternatives to traditional meat from animals.
