The future of face masks

Building better air filters could help head off the next pandemic. At the 74th Annual Meeting of the APS Division of Fluid Dynamics, scientists will present the latest results on how future face masks may work, what happens ...

Melting glasses from unmeltable compounds

Glasses are an indispensable part of everyday life. One of the most important reasons for this is that glass objects can be manufactured almost universally and inexpensively in a wide variety of shapes and sizes using their ...

Creating cotton that is fireproof and comfortable

State-of-the-art flame retardant cotton textiles suffer from release of formaldehyde and are uncomfortable to wear. Empa scientists managed to circumvent this problem by creating a physically and chemically independent network ...

Janus graphene opens doors to sustainable sodium-ion batteries

In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel ...

A transformative metasurface based on a zerogap embedded template

A research team, led by Professor Dai-Sik Kim in the Department of Physics at UNIST has developed a new technique of predefining the crack pattern on a flexible substrate by a sequential deposition of metallic layers which ...

Carbon black recycled from car tires

Until now, waste tires have been used mainly for recovering energy sources: Only small proportions of the carbon black contained in these tires are recycled, since mineral ash accounts for around 20 percent of its content. ...

Super-selective catalysts key to carbon conversion

Catalysts could prove to be the key to converting carbon dioxide and carbon monoxide into value-added products but their effectiveness depends on them being selective in how they work.
