Unfortunately, creating synthetic zeolites is very complex. Researchers at KU Leuven, Ghent University and the University of Antwerp have discovered a way to make new zeolites quickly. “The method is faster than existing methods and contributes to the development of a more sustainable, greener chemical industry," says KU Leuven Professor Christine Kirschhock.
Zeolites are best known for their ubiquitous use as water softeners in detergents and as catalysts in industry. A catalyst is a mediator that increases the efficiency of chemical reactions, saving huge amounts of energy. Zeolites are robust and reusable – making them environmentally friendly catalysts.
There are various types of zeolites, each with their own specific structure and porous make-up. Naturally-occurring zeolites are often unsuitable for industrial applications because their pores are small. Developing synthetic zeolites, however, is very complex and often a matter of trial and error.
Around 200 different synthetic zeolites currently exist, of which only 20 are actually used in industry. The desired properties of the zeolite – its composition, pore size, reusability and so on – change with each new application. Until now, designing a zeolite with predetermined characteristics was impossible.
Researchers from Leuven, Ghent and Antwerp have now experimentally demonstrated that it is possible to cut zeolite building blocks and rearrange them into a new structure. Professor Christine Kirschhock of KU Leuven explains: “A zeolite can be thought of as a set of merged building blocks. We are now able to separate certain blocks of a zeolite and then reassemble them into different configurations, depending on the desired properties.”
This generic method for creating new zeolites has significant advantages: “In addition to new possibilities for applications, the method contributes to the development of a more sustainable, greener chemical industry. It is the first-ever example of customizable zeolite design.”

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
