X-ray insights may enable better plastics production

Analysis helps to understand fragmentation of catalyst particles in ethylene polymerisation

30-Sep-2021

An X-ray study at DESY is pointing the way towards a better understanding of plastics production. A team led by Utrecht University investigated so-called Ziegler-type catalysts, the workhorses in the world's polyethylene and polypropylene production, at DESY's X-ray source PETRA III. As the ...

The indestructible light beam

Researchers create special light waves that can penetrate even opaque materials as if the material was not even there

14-Apr-2021

Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light ...

Optimal information about the invisible

How do you measure objects that you can't see under normal circumstances?

27-Jan-2021

Laser beams can be used to precisely measure an object’s position or velocity. Normally, however, a clear, unobstructed view of this object is required – and this prerequisite is not always satisfied. In biomedicine, for example, structures are examined, which are embedded in an irregular, ...

Start-ups in Germany are rarely based on radical innovations

Accelerating effect through crises

13-Aug-2020

The founding processes in the "alternative energies" and "information technologies" sectors are proceeding faster in Germany than in the USA. This is the result of an international research project of the IfM Bonn and the University of Utrecht, which evaluated a survey of founders in Germany, the ...

Support drives fate of protected gold nanoclusters as catalysts

The choice of a support material may have drastic effects on the structure of the catalyst

17-Jun-2020

In collaboration with experimentalists from Ghent University, Belgium and Utrecht University, Netherlands, researchers at the Nanoscience Center (NSC) at the University of Jyväskylä, have recently discovered that the choice of a support material for model catalysts, made from gold nanoclusters ...

Secrets of fluorescent microalgae could lead to super-efficient solar cells

13-May-2019

Tiny light-emitting microalgae, found in the ocean, could hold the secret to the next generation of organic solar cells, according to new research carried out at the Universities of Birmingham and Utrecht. Microalgae are probably the oldest surviving living organisms on the planet. They have ...

Scientists develop diesel that emits far less CO2

14-Dec-2015

Researchers from KU Leuven and Utrecht University have discovered a new approach to the production of fuels. Their new method can be used to produce much cleaner diesel. It can quickly be scaled up for industrial use. In 5 to 10 years, we may see the first cars driven by this new clean ...

Microscopic tracking of photocatalysis

New measuring technique brings solar fuels closer

30-Aug-2012

Detailed molecular-scale measurements of a chemical reaction accelerated by sunlight have been made for the first time ever. Chemists at Utrecht University and the Friedrich Schiller University Jena (Germany) have set up a special microscope to simultaneously take part in and observe the ...

Irregularities in catalyst inhibit crude oil conversion

Blueprint of the catalyst's interior

23-Sep-2009

Irregularities in industrial catalysts can inhibit the conversion of crude oil, Utrecht University chemists have concluded. They were the first to provide a detailed blueprint of the interior of a commercially used catalyst for e.g. the production of transportation fuels from crude oil. They ...
