Modified clay can remove herbicide from water

14-Feb-2020

By creating neatly spaced slits in a clay mineral, University of Groningen Professor of Experimental Solid State Physics Petra Rudolf was able to filter water to remove a toxic herbicide. After removing the pollutant by heating the material, the clay can be reused. Together with colleagues from ...

First view of hydrogen at the metal-to-metal hydride interface

05-Feb-2020

University of Groningen physicists have visualized hydrogen at the titanium/titanium hydride interface using a transmission electron microscope. Using a new technique, they succeeded in visualizing both the metal and the hydrogen atoms in a single image, allowing them to test different ...

Optimized Binding Cavity

Directed evolution of a designer enzyme with an unnatural catalytic amino acid

05-Feb-2019

The impressively high conversion rates of natural enzymes partly result from increasing the catalytic activity of a selected few amino acid side chains through precise positioning within the protein binding cavity. Scientists have now demonstrated that such fine-tuning is also possible for ...

Creating a 2-D platinum magnet

10-Apr-2018

University of Groningen physicists have induced magnetism in platinum with an electric field created by a paramagnetic ionic liquid. As only the surface of the platinum is affected, this creates a switchable 2D ferromagnet. Platinum is used a lot in jewellery and electronics. Although this ...

Probing exotic ices

12-Oct-2017

Water is everywhere. But it's not the same everywhere. When frozen under extreme pressures and temperatures, ice takes on a range of complex crystalline structures. Many of the properties and behaviors of these exotic ices remain mysterious, but a team of researchers recently provided new ...

Carbon nanotubes self-assemble into tiny transistors

06-Apr-2017

Carbon nanotubes can be used to make very small electronic devices, but they are difficult to handle. University of Groningen scientists, together with colleagues from the University of Wuppertal and IBM Zurich, have developed a method to select semiconducting nanotubes from a solution and make ...

Cool combination produces easier carbon bonds

25-Apr-2016

By combining two century-old techniques in organic chemistry, Syuzanna Harutyunyan is able to make organic compounds with greater ease and precision. Such compounds are important for drug discovery and development. Almost 90 percent of known active pharmaceutical ingredients contain one or more ...

The origins of abiotic species

06-Jan-2016

How can life originate from a lifeless chemical soup? This question has puzzled scientists since Darwin's 'Origin of species'. University of Groningen chemistry professor Sijbren Otto studies 'chemical evolution' to see if self-organization and autocatalysis will provide the answer. His research ...

Superconductor survives ultra-high magnetic field

16-Nov-2015

Physicists from the universities of Groningen and Nijmegen (the Netherlands) and Hong Kong have discovered that transistors made of ultrathin layers molybdeendisulfide (MoS2) are not only superconducting at low temperatures but also stay superconducting in a high magnetic field. This is a unique ...

First realization of an electric circuit with a magnetic insulator using spin waves

16-Sep-2015

Researchers at the University of Groningen, Utrecht University, the Université de Bretagne Occidentale and the FOM Foundation have found that it is possible to make an electric circuit with a magnetic insulator. This was first deemed impossible. The circuit is realized using spin waves: wave-like ...
