High-tech lubricant forms by itself when needed

Precisely where friction is high, lubricants are created that ensure lower friction: At the Vienna University of Technology, this was achieved with special 2D materials

20-Jun-2023 - Our bodies have a few things in common with machines: We have moving joints, friction and wear occur, so you need suitable lubricants. The body produces them naturally all by itself - something similar is now possible with machines. By choosing suitable materials, it is possible to achieve that ...

Nanoporous intermetallic compounds that boost hydrogen production

20-Oct-2022 - Hydrogen has the highest energy density (120 MJ/kg) of all known substances, approximately three times more than diesel or gasoline, meaning it could play a pivotal role in sustainable energy systems. But the efficient production of hydrogen by simple water splitting requires highly performing ...

Climate protection: CO₂ turned into methanol

TU Wien has developed a chemical process that uses special catalysts to turn climate-damaging carbon dioxide into valuable methanol

29-Jun-2022 - For reasons of climate protection, carbon dioxide must not be released into the atmosphere. Wherever the formation of carbon dioxide cannot be prevented, it should be captured and converted into other substances. The best possible solution is creating substances that have value and can be sold. A ...

How light activates MoS2 layers to become catalysts

08-Mar-2021 - Thin films of molybdenum and sulfur belong to a class of materials that can be considered for use as photocatalysts. Inexpensive catalysts such as these are needed to produce hydrogen as a fuel using solar energy. However, they are still not very efficient as catalysts. A new instrument at the ...

2D sandwich sees molecules with clarity

Researchers adapt 2D 'sandwich' for surface-enhanced Raman spectroscopy

18-May-2020 - A sandwich of molybdenum, sulfur and selenium turns out to be deliciously useful for detecting biomolecules. Tests at Rice University's Brown School of Engineering of a two-dimensional Janus compound showed it could be an effective and universal platform for improving the detection of ...

New catalyst recycles greenhouse gases into fuel and hydrogen gas

20-Feb-2020 - Scientists have taken a major step toward a circular carbon economy by developing a long-lasting, economical catalyst that recycles greenhouse gases into ingredients that can be used in fuel, hydrogen gas, and other chemicals. The results could be revolutionary in the effort to reverse global ...
