Transferring power from Africa to Europe via a high voltage direct current (HVDC) transmission line could be a sustainable business model with added value for both regions. This is the conclusion reached by researchers in the EU-sponsored BETTER project.
A metal-free alternative catalyst for fuel cells may be at hand. A team of chemists introduces a new approach that uses a molecular catalyst system instead of solid catalysts. Although molecular catalysts have been explored before, earlier examples were much less efficient than the traditional platinum catalyst.
The quality of waters can be assessed using of the organisms occurring therein. This approach often results in errors, because many species look alike. Therefore, new methods focus on DNA analyses instead.
Biodegradable drinking cups or vegetable wrapping foil: the bioplastic known as polylactic acid (PLA) is already a part of our everyday lives. And yet, PLA is not yet considered a full alternative to traditional petroleum-based plastics, as it is costly to produce. Researchers now present a way to make the PLA production process more simple and waste-free.
