Partners from Aalborg, Steeper Energy, the Paul Scherrer Institute (CH) and the Norwegian University of Science and Technology, amongst others, will be giving an update of the project's progress.

August 10, 2016: Mads Mørk Jensen has returned from the University of Bologna

Mads performed a research visit at the University of Bologna, Italy with Prof Fabbri.

After his 4 month stay in Italy Mads has now returned to continue his PhD in Aarhus with the AC3 group.

Welcome back!

April 27, 2016: Two AC3 presentations at the RRB Conference 2016, Ghent, Belgium

Both René and Patrick will be presenting their work at this year's 12th International Conference on Renewable Resources & Biorefineries 30 – 31 May & 1 June 2016 in Ghent, Belgium.

René will be giving a talk on his work on the effects of different pre-treatment techniques of Miscanthus for the preparation of a hydrothermal liquefaction feedstock. René performed a principal component analysis to investigate the pre-treatment effects on both the bio-crude and aqueous phase. 

Patrick will talk about the effects of recycling the water phase during hydrothermal liquefaction. This incorporates results from our continuous HTL facility, micro batch reactors and utilises the analytical techniques developed within AC3. 

 More info and the program of the conference can be found here: http://www.rrbconference.com/

April 10, 2016: Mads Mørk Jensen has departed on a 4 month research visit to the University of Bologna

Mads has left Aarhus for a research visit at the University of Bologna, Italy. He will be joining the research group of Professor Daniele Fabbri until the end of August. Prof Fabbri is an expert on pyrolysis and his research group has developed some advanced characterisation techniques using analytical pyrolysis gas-chromatography mass-spectrometry (Py-GC-MS).

Mads will be applying the techniques to some of his lignin derived HTL samples to be able to characterise the heavy molecular weight fraction. You can read more about the methodology here: pubs.acs.org/doi/abs/10.1021/acs.energyfuels.5b02688

February 23, 2016: Featured Article in Environmental Science & Technology by Marianne Glasius

Congratulations to Marianne Glasius who just published a featured article in Environmental Science & Technology in collaboration with Allen H. Goldstein from the University of California, Berkeley (USA). The title of the review article is Recent discoveries and future challenges in atmospheric organic chemistry. The article can be found online at: pubs.acs.org/doi/abs/10.1021/acs.est.5b05105

January 28, 2016: Master Thesis Defence - Louise Skov Iversen

Louise Skov Iversen will be presenting her Master research Thesis with the title “Identification and quantification of water-soluble ions and organic trace compounds in aerosols from North Greenland” Friday the 29th January. This work investigates the application of analytical chemistry to investigate the chemical composition of aerosols, which are known to affect how aerosols influence climate directly and indirectly. The exam will be on Friday January 29 at 12.15 in Aud VI (room 1510-213), Department of Chemistry, Langelandsgade 140, Aarhus. 
The program is a presentation by Louise (about 45 min) followed by about 30 min of questions from censor (Jacob Klenø Nøjgaard, Department of Environmental Science Atmospheric chemistry and physics, AU) and the supervisor (Marianne Glasius).

After the exam there will be a reception in Aud VI (room 1510-213) starting approximately at 15.00.

    Louise Skov Iversen visits Villum Research Station in north Greenland

    20/5-2015: Master student Louise Skov Iversen has recently returned after almost three weeks at Villum Research Station in north Greenland where she successfully collected aerosol samples. The samples will now be analyzed for molecular tracers to provide information on their formation and sources. Furthermore, the physical-chemical properties related to cloud formation will be investigated. The project contributes to the scientific understanding of sources and climate effects of aerosols in the Arctic, and is a collaboration between the research groups of Merete Bilde (Dep. of Chemistry), Andreas Massling (Dep. of Environmental Science) and Marianne Glasius (Dep. of Chemistry and iNANO).
