Electron correlations in carbon nanostructures

Behaviour of electrons in graphene nanoribbons elucidated

05-Dec-2019

New materials are needed to further reduce the size of electronic components and thus make devices such as laptops and smartphones faster and more efficient. Tiny nanostructures of the novel material graphene are promising in this respect. Graphene consists of a single layer of carbon atoms and, ...

New route to carbon-neutral fuels from carbon dioxide discovered

18-Sep-2019

If the idea of flying on battery-powered commercial jets makes you nervous, you can relax a little. Researchers have discovered a practical starting point for converting carbon dioxide into sustainable liquid fuels, including fuels for heavier modes of transportation that may prove very difficult ...

Double graphene sandwich provides protection against corrosion

07-Jun-2018

”Normally it’s not a huge success that not a damn thing has happened after 120 days.” These words belong to Professor Peter Bøggild after a four-month period where a novel type of anticorrosion coating was tested. The nanomaterial graphene plays a crucial role in this new type of coating. ...

Elastocaloric materials enable more efficient, 'green' cooling

26-Mar-2015

Move over, vapor compression cooling technology. Emerging "elastocaloric" refrigeration is potentially much more efficient and, unlike vapor compression, relies on environmentally-friendly refrigerants. In elastocaloric materials a change in mechanical stress can create a change in temperature.In ...

Chemist develops X-ray vision for quality assurance

01-Aug-2014

It is seldom sufficient to read the declaration of contents if you need to know precisely what substances a product contains. In fact, to do this you need to be a highly skilled chemist or to have genuine X-ray vision so that you can look directly into the molecular structure of the various ...

Newly discovered catalyst could lead to clean methanol

04-Mar-2014

An international research team has discovered a potentially clean, low-cost way to convert carbon dioxide into methanol, a key ingredient in the production of plastics, adhesives and solvents, and a promising fuel for transportation. Scientists from Stanford University, SLAC National Accelerator ...

X-ray laser reveals chemical reaction

18-Mar-2013

What happens when a chemical bond is broken? That question was recently answered with the help of a so-called free electron x-ray laser, which makes it possible to follow in real time how bindings in a molecule are changed and broken. The study, published in Science, found, among other things, ...

CFD collaboration between GEA Niro and DTU

Building a better spray dryer

08-Aug-2011

GEA Niro is working hand-in-hand with the Technical University of Denmark (DTU), to simulate the fluid dynamics that take place within a full-sized spray dryer. This is done using a scaled down model with water instead of air. The process allows experiments to be performed at a laboratory level ...
