Repellant and Hostile to Bacteria

Zwitterionic polymeric sulfur ylides: antifouling coating with a synergistic effect

13-Sep-2023 - Bacteria that gather into biofilms on the surfaces of implants, catheters, breathing tubes, and other medical components are a serious health hazard. In the journal Angewandte Chemie, a research team from the Netherlands has now introduced a new material based on poly(sulfur ylides) that—when ...

Breakthrough: Scientists develop artificial molecules that behave like real ones

The uses of this new technique are endless: ‘We have only begun to imagine what we can use this for. We have so many ideas...’

12-Jun-2023 - Scientists from the Radboud University have developed synthetic molecules that resemble real organic molecules. A collaboration of researchers, led by Alex Khajetoorians and Daniel Wegner, can now simulate the behaviour of real molecules by using artificial molecules. In this way, they can tweak ...

Bacteria generate electricity from methane

"We create a kind of battery with two terminals, where one of these is a biological terminal and the other one is a chemical terminal"

13-Apr-2022 - Generating power while purifying the environment of greenhouse gases should be achievable using bacteria. In a new publication, microbiologists from Radboud University have demonstrated that it is possible to make methane-consuming bacteria generate power in the lab. The ...

Quantifying exchange interactions on the atomic scale

Research team from Kiel and Nijmegen studies magnetic spiral structure

11-Mar-2020 - Today, there is a great effort to scale down magnetic memory towards nanometer-sized bits in order to ultimately store information in a single magnetic atom. This makes it necessary to image magnetic properties on the atomic scale. At the heart of magnetism is the exchange interaction – proposed ...

X-rays show birth of semiconductor for blue LEDs

Gallium nitride is the second most important semiconductor material after silicon

28-Feb-2020 - Using a special pressure furnace, an international team of researchers has analysed the initial stages of the growth of the semiconductor gallium nitride with X-ray light. The observations show for the first time the atomic structure of the interface of the semiconductor material with liquid ...

Graphite mimics iron's magnetism

06-Oct-2009 - Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In ...

The Million Euro Nanoreactor

04-Dec-2007 - Jeroen Cornelissen of the Institute for Molecules and Materials at the Radboud University in the Netherlands has recently received EUR 1 million from EURYI (European Young Investigator Awards). The award will allow Cornelissen (35), an assistant professor at Radboud and a member of the scientific ...

Nanoreactors for Reaction Cascades

Nanoscopic bubbles with plastic membrane and built-in enzymes for multistep one-pot reactions

21-Aug-2007 - Living cells are highly complex synthetic machines: Numerous multistep reactions run simultaneously side by side and with unbelievable efficiency and specificity. For these mainly enzymatic reactions to work so well collectively, nature makes use of a variety of concepts. One of the most ...

Plants do not produce methane gas

Dutch scientists disprove recent claim that living plants would produce a large part of the greenhouse gas methane.

02-May-2007 - A group of scientists of Plant Research International (Wageningen UR), Radboud University Nijmegen, Utrecht University, and the Wageningen-based companies IsoLife and Plant Dynamics has demonstrated that the 'methane emission' by living plants is negligibly small. This is shown in their ...
