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.
A significant step has been made for potential Carbon Capture and Storage (CCS) deployment, with the publication of the results from the world's first experiment into the realistic simulation of potential environmental impact of a submarine CO2 leakage.
Carbon monoxide-rich exhaust gases from steel plants are only being reclaimed to a minor extent as power or heat. Researchers have developed a new recycling process for this materially unused carbon resource: They successfully produced fuel and specialty chemicals from these exhaust gases on a laboratory scale.
By 2030 around half of all electricity in Europe should come from renewable energies in order to reach EU climate targets. This applies to Germany, France, the Benelux countries, Austria and Switzerland. Varying volumes of national wind and solar supply can be balanced out through the cross-border integration of power systems.
