Titanium catalyst enables reactions with the help of green light

Cost-effective and non-toxic alternative to the ruthenium and iridium catalysts used so far

23-Apr-2020

For the first time, chemists at the University of Bonn and Lehigh University in Bethlehem (USA) have developed a titanium catalyst that makes light usable for selective chemical reactions. It provides a cost-effective and non-toxic alternative to the ruthenium and iridium catalysts used so far, ...

Unexpected discovery: Blue-green algae produce oil

06-Mar-2020

Cyanobacteria - colloquially also called blue-green algae - can produce oil from water and carbon dioxide with the help of light. This is shown by a recent study by the University of Bonn. The result is unexpected: Until now, it was believed that this ability was reserved for plants. It is ...

In-depth insights into glass corrosion

Researchers observe the reaction of silicate glass with aqueous solutions in real time

04-Mar-2019

Silicate glass has many applications, including the use as a nuclear waste form to immobilize radioactive elements from spent fuel. However, it has one disadvantage - it corrodes when it comes into contact with aqueous solutions. Scientists at the University of Bonn were able to observe in detail ...

Tiny nanomachine successfully completes test drive

11-Apr-2018

Together with colleagues from the USA, scientists from the University of Bonn and the research institute Caesar in Bonn have used nanostructures to construct a tiny machine that constitutes a rotatory motor and can move in a specific direction. The researchers used circular structures from ...

Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

16-Aug-2017

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information ...

Sorting machine for atoms

13-Feb-2017

Physicists at the University of Bonn have cleared a further hurdle on the path to creating quantum computers: in a recent study, they present a method with which they can very quickly and precisely sort large numbers of atoms. Imagine you are standing in a grocery store buying apple juice. ...

Nanofur for oil spill cleanup

Hairy plant leaves are highly oil-absorbing

22-Aug-2016

Some water ferns can absorb large volumes of oil within a short time, because their leaves are strongly water-repellent and, at the same time, highly oil-absorbing. Researchers of KIT, together with colleagues of Bonn University, have found that the oil-binding capacity of the water plant results ...

New insights into the creation of heavy elements

04-Dec-2015

Alpha particles, as the nuclei of the helium atom are also called, play a decisive role in the formation of heavier elements. Carbon, for instance, is formed from the fusion of these alpha particles. If another helium nucleus is added, oxygen is formed - another prerequisite for the development ...

Atoms can be in 2 places at the same time

Researchers of the University of Bonn have shown that cesium atoms do not follow well-defined paths

22-Jan-2015

Can a penalty kick simultaneously score a goal and miss? For very small objects, at least, this is possible: according to the predictions of quantum mechanics, microscopic objects can take different paths at the same time. The world of macroscopic objects follows other rules: the football always ...

The contribution of particulate matter to forest decline

20-Jun-2013

Air pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles. Bonn University scientists have now discovered a responsible mechanism: particulate matter salt compounds that become deliquescent because of humidity and form a wick-like ...
