Researchers from the University of Antwerp and KU Leuven have succeeded in developing a process that purifies air and, at the same time, generates power. The device must only be exposed to light in order to function.“We use a small device with two rooms separated by a membrane,” explains Professor Sammy Verbruggen (UAntwerp/KU Leuven). “Air is purified on one side, while on the other side hydrogen gas is produced from a part of ...

"Photoredox catalysis" has become an essential way to synthesise novel organic compounds.This type of chemistry may soon be used even more widely—and less expensively— thanks to University of Rochester researchers.In a paper published recently in theJournal of the American Chemical Society, the labs of Todd Krauss and Daniel Weix demonstrate for the first time how light emitting quantum dots can be used as photoredox catalysts to crea...

An international team of scientists has developed a new way to produce single-layer graphene from a simple precursor: ethene – also known as ethylene – the smallest alkene molecule, which contains just two atoms of carbon.By heating the ethene in stages to a temperature of slightly more than 700ºC - hotter than had been attempted before – the researchers produced pure layers of graphene on a rhodium catalyst substrate.

This year’s HANNOVER MESSE had the clear objective, to make the benefits of digitalisation tangible, and after five action-packed days at the world’s leading trade fair for industrial technology, the organisers spoke about the thriving event.A large number of solution-seekers gathered in Hannover to immerse themselves in the potential of intelligent robots, adaptive machines and integrated energy systems, taking attendance to new heig...

Early science results from NASA’s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet’s surface than previously thought.

Panasonic has announced the extension of its HL seriesELDCs (Electric Double Layer Capacitors), which offer low resistance combined with guaranteed long life over a wide temperature range, from -40°C to +85°C.

In order to accelerate the commercialisation of hydrogen fuelled vehicles, both in Spain and the UK,ULEMCo has announced a collaboration with Spanish company H2B2.The companies have signed a memorandum of understanding that sees the firms enter a non-exclusive partnership to maximise the opportunity for the use and supply of hydrogen economically through scaled production.

The ability to assemble electronic building blocks consisting of individual molecules is an important objective in nanotechnology. An interdisciplinary research group at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) is significantly closer to achieving this goal. The team of researchers headed by Prof. Dr. Sabine Maier, Prof. Dr. Milan Kivala and Prof. Dr. Andreas Görling has successfully assembled and tested conductors a...

Limitation in energy density of batteries means in practice reduced driving range for electric cars, which is the largest obstacle to these vehicles entering the market. But, new technology using the reaction of metal and air could have a major impact on battery life. The EU-funded project NECOBAUT (New concept of metal-air battery for automotive application based on advanced nanomaterials) was launched with the aim to incorporate nanomaterials i...

Researchers from Lund University in Sweden have succeeded in producing nanotubes from a single building block using so-called molecular self-recognition. The tube can also change shape depending on the surrounding environment. The results can contribute to the future development of transport channels for drugs through the cell membrane.
