Hydrogen alarm for remote hydrogen leak detection

Hydrogen is considered as one of the promising alternative energy sources. Nevertheless, its application as an energy carrier is complicated due to its highly explosive nature when mixed with oxygen. These dangerous situations ...

Dietary fiber effectively purifies carbon nanotubes

A new, cheaper method easily and effectively separates two types of carbon nanotubes. The process, developed by Nagoya University researchers in Japan, could be upscaled for manufacturing purified batches of single-wall carbon ...

Engineers report a new low-power lighting technology

Researchers from the Moscow Institute of Physics and Technology and Lebedev Physical Institute of the Russian Academy of Sciences have designed and tested a prototype cathodoluminescent lamp for general lighting. The new ...

Electron beam strengthens recyclable nanocomposite

Polymers reinforced with carbon fibers combine strength and low weight. They also boast significant green credentials as they are less resource-intensive during production and use, and they are readily recycled. While the ...

How to program materials

Ali Gooneie simulates on his computer what holds the world together right at its very core: atoms, molecules, molecular chains and bundles—then lumps and fibers, which emerge from these. With his calculations, the Empa ...
