Flipsen, S.F.J. (author)It is impossible to imagine life without portable electronics like the laptop computer and cell phone. All these products are powered by a battery, granting them grid independence and all-round protability. Connectivity to the internet and an increase of functionality demands for a better battery. The d1irect methanol fuel cell (DMFC) system...doctoral thesis 2010

Szécsényi, A. (author)In this thesis we presented comprehensive studies on methane activation by binuclear Fe-oxo sites located in porous MOF and zeolite frameworks. Many of such studies have been previously performed, however the main focus was usually on the C-H bond activation of methane. Here we focused on the whole reaction mechanism including the activation of...doctoral thesis 2019

Phongprueksathat, N. (author)Since the industrial revolution in the 1760s, the CO2 concentration in the atmosphere has been rising incessantly driving global warming closer to the point of no return. The world requires urgent actions to not only reduce CO2 emissions but also capture the CO2 for utilization to mitigate the future environmental crisis. CO2 hydrogenation to...doctoral thesis 2023

Effect and behaviour of different substrates in relation to the formation of aerobic granular sludgePronk, M. (author), Abbas, B. (author), Al-zuhairy, S.H.K. (author), Kraan, R. (author), Kleerebezem, R. (author), Van Loosdrecht, M.C.M. (author)When aerobic granular sludge is applied for industrial wastewater treatment, different soluble substrates can be present. For stable granular sludge formation on volatile fatty acids (e.g. acetate), production of storage polymers under anaerobic feeding conditions has been shown to be important. This prevents direct aerobic growth on readily...journal article 2015

De Jonge, L.P. (author), Douma, R.D. (author), Heijnen, J.J. (author), Van Gulik, W.M. (author)A sampling procedure for quantitative metabolomics in Penicillium chrysogenum based on cold aqueous methanol quenching was re-evaluated and optimized to reduce metabolite leakage during sample treatment. The optimization study included amino acids and intermediates of the glycolysis and the TCA-cycle. Metabolite leakage was found to be minimal...journal article 2011

Lameiras, F. (author), Heijnen, J.J. (author), Van Gulik, W.M. (author)In view of the high citric acid production capacity of Aspergillus niger, it should be well suited as a cell factory for the production of other relevant acids as succinic, fumaric, itaconic and malic. Quantitative metabolomics is an important omics tool in a synthetic biology approach to develop A. niger for the production of these acids. Such...journal article 2015

(author)Accurate determination of intracellular metabolite levels requires reliable, reproducible techniques for sampling and sample treatment. Quenching in 60% (v/v) methanol at ?40°C is currently the standard method for sub-second arrest of metabolic activity in microbial metabolomics but there have been contradictory reports in the literature on...journal article 2008

Van Rheenen, E.S. (author), Scheffers, E.L. (author), Zwaginga, J.J. (author), Visser, K. (author)It is essential to use alternative fuels if we are to reach the emission reduction targets set by the IMO. Hydrogen carriers are classified as zero-emission, while having a higher energy density (including packing factor) than pure hydrogen. They are often considered as safe alternative fuels. The exact definition of what safety entails is often...journal article 2023

(author)The production of valuable aromatics and the rapid catalyst deactivation due to coking are intimately related in the zeolite-catalyzed aromatization reactions. Here, we demonstrate that these two processes can be decoupled by promoting the Ga/HZSM-5 aromatization catalyst with Ca. The resulting bimetallic catalysts combine high selectivity to...journal article 2022
