Reaction at the heart of many renewable energy technologies
New insights into how proton-coupled electron transfers occur at an electrode could help researchers design more efficient fuel cells and electrolyzers. A key chemical reaction - in which the movement of protons between the surface of an electrode and an electrolyte drives an electric current - is a critical step in many energy technologies, including fuel cells and the electrolyzers used to produce hydrogen gas.

This is how Professor René Janssen paves the way to better solar cells
This is how Professor René Janssen paves the way to better solar cells
A professor at TU/e and colleagues have found a way to improve perovskite solar cells. An electric car, heat pump, or robotic lawn mower: the world is electrifying, and so more and more roofs are full of solar panels. The Netherlands is even among the European leaders when it comes to generating solar energy.

Meteorite Analysis Shows Earth’s Building Blocks Contained Water
When our Sun was a young star, 4.56 billion years ago, what is now our solar system was just a disk of rocky dust and gas. Over tens of millions of years, tiny pebbles of dust coalesced, like a snowball rolling larger and larger, to become kilometer-sized "planetesimals"-the building blocks of Earth and the other inner planets.

The rock that creates clouds
The rock that creates clouds
Feldspar is very common in rocks. As atmospheric dust, this mineral contributes efficiently to cloud formation. Researchers at TU Wien have now discovered what happens during this process. Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role.

Common Chemical Production Made Safer, More Environmentally Friendly
Common Chemical Production Made Safer, More Environmentally Friendly
The chemical industry has long been shadowed by unwelcome images of billowing smokestacks and pipes discharging toxic effluent. Modern manufacturing practices have done much to mitigate the industry's environmental impact, but there remains room for improvement. Making chemistry more environmentally friendly is a passion and major research focus for Caltech's Karthish Manthiram , professor of chemical engineering and chemistry, and a William H. Hurt Scholar.

Asteroid Samples Reveal Origins of Organic Molecules in the Early Solar System
Carbon is the building block of biological life on Earth. The element is present in many compounds, such as the sugars, proteins, and carbohydrate molecules that make up everything from animals to plants to bacteria. One particular carbon-based molecule, called polycyclic aromatic hydrocarbons (PAHs), is both ubiquitous on Earth and abundant in space.

How is an ionic liquid structured when it comes into contact with a wall?
Publication of the Physics Laboratory and Chemistry Laboratory in the journal Langmuir on November 16, 2023. News by CNRS Chemistry on December 19, 2023. Water flowing over soluble rocks can create patterns of multiple troughs bordered by sharp ridges.

Utrecht chemists discover mechanism to design more sustainable molecular catalysts
Utrecht scientists, under the supervision of Marc-Etienne Moret, have discovered a new mechanism to build molecular catalysts. The new mechanism involves the earth-abundant metal nickel instead of precious metals that are often used as part of molecular catalysts. Moret: "This discovery initiates a new area of research that brings about a whole new concept for the design of more sustainable catalysts." In 2017, chemistry researcher Marc-Etienne Moret received an ERC Starting Grant  to study new catalysts with better properties.
