Nitrogen monoxide (NO) is hazardous and catalytic techniques are used to reduce NO to molecular nitrogen and water using ammonia as a reducing agent. This is a challenging problem given that diesel exhaust contain only one NO molecule per 300 oxygen molecules.
Nanoparticles play a key role in catalysis, which for example is used to clean exhaust gases from our cars. To save energy and provide clean air, it is desirable to understand how the catalytic reactions proceed over the nanoparticles. In his PhD thesis, Mikkel Jørgensen has developed simulation methods to do so. Now he receives the Best Thesis Award for his efforts.
Catalysts are not only used to speed up chemical transformations. They are also used to selectively steer reactions into desired molecules.
By studying materials down to the atomic level, researchers at Chalmers University of Technology have found a way to make catalysts more efficient and environmentally friendly. The results have been published in Nature Communications. The methods can be used to improve many different types of catalysts.
How does the catalytic activity of a nanoparticle depend on size and shape? This is a fundamental question that has been studied by PhD Student Mikkel Jørgensen and Professor Henrik Grönbeck, using a newly developed computational technique for first principles based kinetic modelling.
Reducing pollution from engine exhaust is an important and very challenging task in our society. Physics Doctor Maxime Van den Bossche has worked out models that explain how molecules “dance” on the surfaces during catalytic reactions. This knowledge can be used to understand how the exhaust from natural gas engines can be cleaned efficiently.
Kirsten Leistner, postdoc at Chemistry and Chemical Engineering, is awarded the L’Oréal-Unesco For women in science-prize which aims to highlight female scientists in the beginning of their career. The ceremony took place in Stockholm, 6th of March. Leisner along with Julia U was given the awarded by Helene Hellmark Knutsson, Minister for Higher Education and Research. - It means a lot to me...
