An international group of researchers led by Arnaud Belloche (MPIfR, Bonn, Germany) reports the first identification of isopropanol in interstellar space, a substance which is used as a sanitizer on Earth. Iso-propanol is the largest alcohol detected so far, demonstrating the increasing complexity of members of one of the most abundant classes of molecule that can be found in space...

New PET-like Plastic made directly from Waste Biomass

EPFL scientists have developed a new, PET-like plastic that is easily made from the – parts of . The plastic is tough, heat-resistant, and a good barrier to gases like oxygen, making it a promising candidate for food packaging. Due to its structure, the new plastic can also be chemically recycled and degrade back to harmless in the environment.

It is becoming increasingly obvious that moving away from fossil fuels and avoiding the accumulation of plastics in the environment are key to addressing the challenge of climate change. In that vein, there are considerable efforts to develop degradable or recyclable polymers made from non-edible plant material referred to as “lignocellulosic biomass.”

Of course, producing competitive biomass-based plastics is not straightforward...

Long-term Liquid Water also on Non-Earth-like Planets?

Low-mass planets with a primordial atmosphere of hydrogen and helium might have the temperatures and pressures that allow water in the liquid phase. The presence of liquid water is favorable for life, so that these planets potentially harbour exotic habitats for billions of years. © (CC BY-NC-SA 4.0) – Thibaut Roger – Universität Bern – Universität Zürich

Liquid water is an important prerequisite for life to develop on a planet. As researchers from the University of Bern, the University of Zurich and the National Centre of Competence in Research (NCCR) PlanetS report in a new study, liquid water could also exist for billions of years on planets that are very different from Earth. This calls our currently Earth-centred idea of potentially habitable planets into question.

Reaction Insights help make Sustainable Liquid Fuels

Elucidation of radical- and oxygenate-driven paths in zeolite-catalysed conversion of methanol and methyl chloride to hydrocarbons, Nature Catalysis (2022)

Methanol, produced from carbon dioxide in the air, can be used to make carbon neutral fuels. But to do this, the mechanism by which methanol is turned into liquid hydrocarbons must be better understood so that the catalytic process can be optimised. Now, using sophisticated analytical techniques, researchers from ETH Zürich and Paul Scherrer Institute have gained unprecedented insight into this complex mechanism.

As we struggle to juggle the impact of emissions with our desire to maintain our energy hungry lifestyle, using carbon dioxide in the atmosphere to create new fuels is an exciting, carbon neutral alternative...
