Hoppe, T. (author), Kuokkanen, Anna (author), Mikkila, Mirja (author), Kahiluoto, Helena (author), Kuisma, Miia (author), Arentsen, M (author), Linnanen, Lassi (author)Nitrogen (N) and phosphorus (P) cycles are absolutely vital in maintaining sustainable food systems. Human activities disturb the natural balance of these cycles by creating enormous additional nutrient fluxes, causing eutrophication of waterways and pollution in land systems. To tackle this problem, sustainable nutrient management is required....journal article 2016

(author)In microbial processes for production of proteins, biomass and nitrogen-containing commodity chemicals, ATP requirements for nitrogen assimilation affect product yields on the energy producing substrate. In Saccharomyces cerevisiae, a current host for heterologous protein production and potential platform for production of nitrogen-containing...journal article 2015

Villanueva, L. (author), Speth, D.R. (author), Van Alen, T. (author), Hoischen, A. (author), Jetten, M.S. (author)Anaerobic ammonium oxidizing (anammox) bacteria are responsible for a significant portion of the loss of fixed nitrogen from the oceans, making them important players in the global nitrogen cycle. To date, marine anammox bacteria found in both water columns and sediments worldwide belong almost exclusively to "Candidatus Scalindua" species....journal article 2014

Kartal, B. (author), De Almeida, N.M. (author), Maalcke, W.J. (author), Op den Camp, H.J.M. (author), Jetten, M.S.M. (author), Keltjens, J.T. (author)Anaerobic ammonium-oxidizing (anammox) bacteria primarily grow by the oxidation of ammonium coupled to nitrite reduction, using CO2 as the sole carbon source. Although they were neglected for a long time, anammox bacteria are encountered in an enormous species (micro)diversity in virtually any anoxic environment that contains fixed nitrogen. It...journal article 2013

Giuntoli, J. (author)This dissertation deals with the characterization of several biomass materials under thermal conversion conditions using small--scale equipment. The fuels are tested under the conditions of slow and fast heating rate pyrolysis and combustion, with the main goal of investigating the chemistry of fuel--bound nitrogen. New energy policies put...doctoral thesis 2010

Migliaccio, A. (author), Zandbergen, B.T.C. (author), Nardini, F.T. (author), Louwerse, M.C. (author)The number of micro and nano satellite projects is expanding. Main focus is on providing these small satellites with the same capabilities as today's larger satellites. In the field of propulsion, efforts are on miniaturization of the on-board propulsion system. This though presents major challenges to the designers. TNO Defence, Security and...conference paper 2010

Sorokin, I.D. (author), Zadorina, E.V. (author), Kravchenko, I.K. (author), Boulygina, E.S. (author), Tourova, T.P. (author), Sorokin, D.Y. (author)Gram-positive bacteria capable of nitrogen fixation were obtained in microoxic enrichments from soda soils in south-western Siberia, north-eastern Mongolia, and the Lybian desert (Egypt). The same organisms were obtained in anoxic enrichments with glucose from soda lake sediments in the Kulunda Steppe (Altai, Russia) using nitrogen-free alkaline...journal article 2009

(author)Precise control over the position of a single quantum object is important for many experiments in quantum science and nanotechnology. We report on a technique for high-accuracy positioning of individual diamond nanocrystals. The positioning is done with a home-built nanomanipulator under real-time scanning electron imaging, yielding an accuracy...journal article 2009

Heremans, F.J. (author), Fuchs, G.D. (author), Wang, C.F. (author), Hanson, R. (author), Awschalom, D.D. (author)We report time-dependent photocurrent and transport measurements of sub-bandgap photoexcited carriers in nitrogen-rich (type Ib), single-crystal diamond. Transient carrier dynamics are characteristic of trapping conduction with long charge storage lifetimes of ? 3?hours. By measuring the photoexcited Hall effect, we confirm that the charge...journal article 2009

Exbrayat, J. F. (author), Breuer, L. (author), Viney, N. R. (author), Seibert, J. (author), Wrede, S. (author), Frede, H. G. (author)Model predictions of biogeochemical fluxes on the landscape scale are highly uncertain, both with respect to stochastic (parameter) and structural uncertainty. The idea of our ensemble modelling approach is to reduce the predictive uncertainty by covering part of the parameter and model structural uncertainty. In this study 4 different models...conference paper 2009

De Jong, W. (author)Fossil fuels still dominate the energy supply in modern societies. The resources, however, are depleting. Therefore, other energy sources are to be exploited further within this century. Biomass is one of the practically CO2 neutral, renewable contributors to the future energy production. Nowadays many modern, high efficiency (combined) power...doctoral thesis 2005
