The E-fuel project of VTT and partners has developed a concept for producing electrofuel from green hydrogen and carbon dioxide using a combination of different methods. On Nov. 21, this paraffinic E-fuel was tested for the first time in Finland on a diesel-powered tractor at AGCO Power’s Linnavuori factory in Nokia. The new electrofuel is also suitable for vehicles that are difficult to electrify, and is therefore an important step in the development of sustainable fuel solutions.

Global climate goals require drastic changes in all aspects of life. Carbon capture and utilization are key to moving towards sustainable fuel solutions for transport...

Computer vision enables contact-free 3D printing, letting engineers print with high-performance materials they couldn’t use before. With 3D inkjet printing systems, engineers can fabricate hybrid structures that have soft and rigid components, like robotic grippers that are strong enough to grasp heavy objects but soft enough to interact safely with humans.

These multimaterial 3D printing systems utilize thousands of nozzles to deposit tiny droplets of resin, ...

They reveal the origin of wine, the age of bones and fossils, and they serve as diagnostic tools in medicine. Isotopes and isotopologues—molecules that differ only in the composition of their isotopes—also play an increasingly important role in astronomy. For example, the ratio of carbon-12 (12C) to carbon-13 (13C) isotopes in the atmosphere of an exoplanet allows scientists to infer the distance at which the exoplanet orbits its central star.

Until now, 12C and 13C bound in carbon monoxide were the only isotopologues that could be measured in the atmosphere of an exoplanet. Now a team of researchers has succeeded in detecting ammonia isotopologues in the atmosphere of a cold brown dwarf.

As the team has just reported in the journal Nature, ammonia could be measured in the f...

MXene and MBene compounds hold promise for new technologies to combat climate change. Some of the thinnest materials known to humankind — MXene and MBene compounds — may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb CO2 molecules from the atmosphere, which could help reduce the harmful effects of climate change by safely sequestering carbon dioxide, according to a review study.
