Remes, A. (author), Pop, A. (author), Manea, F. (author), Baciu, A. (author), Picken, S.J. (author), Schoonman, J. (author)The aim of this study was the preparation, characterization, and application of a multi-wall carbon nanotubes-epoxy composite electrode (MWCNT-EP) with 25%, wt. MWCNTs loading for the voltammetric/amperometric determination of pentachlorophenol (PCP) in aqueous solutions. The structural and morphological aspects of the MWCNT-EP composite...journal article 2012

(author)We fabricate and characterize carbon-fiber tips for their use in combined scanning tunneling and force microscopy based on piezoelectric quartz tuning fork force sensors. An electrochemical fabrication procedure to etch the tips is used to yield reproducible sub-100-nm apex. We also study electron transport through singlemolecule junctions...journal article 2012

Han, B. (author), Yang, Z. (author), Shi, X. (author), Yu, X. (author)This paper preliminarily investigates the general transport properties (i.e., water sorptivity, water permeability, and gas permeability) of carbon-nanotube/cement composites. Carboxyl multi-walled carbon nanotubes (MWNTs) are dispersed into cement mortar to fabricate the carbon nanotubes (CNTs) reinforced cement-based composites by applying...journal article 2012

Galgani, P. (author)The Master’s programme Industrial Ecology is jointly organised by Leiden University and Delft University of Technology. In some areas of Sub-Saharan Africa appropriate organic waste management technology could address development issues such as soil degradation, unemployment and energy scarcity, while at the same time providing climate benefits....master thesis 2012

Van Wijngaarden, W.K. (author), Vermolen, F.J. (author), Van Meurs, G.A.M. (author), Vuik, C. (author)Biogrout is a new method for soil reinforcement, which is based on microbialinduced carbonate precipitation. Bacteria and reactants are flushed through the soil, resulting in calcium carbonate precipitation and consequent soil reinforcement. Bacteria are crucially important in the Biogrout process since they catalyse the reaction. Hence, to...journal article 2012

Huwald, H. (author), Selker, J.S. (author), Tyler, S.W. (author), Calaf, M. (author), Van de Giesen, N.C. (author), Parlange, M.B. (author)The movement of air in natural porous media is complex and challenging to measure. Yet gas transport has important implications, for instance, for the evolution of the seasonal snow cover and for water vapor transport in soil. A novel in situmulti-sensor measurement system providing high-resolution observation of gas transport in snow is...journal article 2012

Van den Dobbelsteen, A.A.J.F. (author), Tillie, N.M.J.D. (author)The City of Amsterdam has ambitious goals as to become climate neutral. This will only be possible through a structured approach to both new and existing neighbourhoods. Following steps from the New Stepped Strategy - as used in the Rotterdam Energy Approach and Planning (REAP) - and using the methodology of Energy Potential Mapping (EPM), the...conference paper 2011

Buchs, G. (author), Barkelid, K.M. (author), Bagiante, S. (author), Steele, G.A. (author), Zwiller, V. (author)We use scanning photocurrent microscopy (SPCM) to investigate individual suspended semiconducting carbon nanotube devices where the potential profile is engineered by means of local gates. In situ tunable p-n junctions can be generated at any position along the nanotube axis. Combining SPCM with transport measurements allows a detailed...journal article 2011

(author)This work presents the development of a non-destructive imaging technique for the investigation of the microstructure of cementite grains embedded in a ferrite matrix of medium-carbon steel. The measurements were carried out at the material science beamline of the European Synchrotron Radiation Facility (ESRF) ID11. It was shown that in-line X...conference paper 2011

Karimi, F. (author)Following the industrial revolution started circa 1750, global energy consumption and, consequently, CO2 emissions have been rapidly increasing. The amount of CO2 rose from 280 ppm in 1750 to 388 ppm in 2010. This increasing amount of GHGs gases, specifically CO2, is the underlying cause of global warming. According to the IPCC report, with the...master thesis 2011

(author)Cultivation methods used to investigate microbial calorie restriction often result in carbon and energy starvation. This study aims to dissect cellular responses to calorie restriction and starvation in Saccharomyces cerevisiae by using retentostat cultivation. In retentostats, cells are continuously supplied with a small, constant carbon and...journal article 2011

Van der Putte, E.A.V. (author)There are a lot of archeological remains in the subsurface of the Netherlands. One of these remains are carbonized wheat grains, which are used in this thesis to answer the question: “Will the archeological remains in the subsurface survive a loading caused by newly build infrastructure or buildings or will they be destroyed?”. In order to give...bachelor thesis 2011

Tang, X. (author)The reliable removal of acid gas components, such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is an important technical challenge. Crude oil and hydrocarbon gas streams may contain high levels of CO2 and/or H2S as contaminants. It is desirable to prevent any contaminant to reach the surface, or to considerably reduce the...doctoral thesis 2011

Jonkers, H.M. (author)A typical durability-related phenomenon in many concrete constructions is crack formation. While larger cracks hamper structural integrity, also smaller sub-millimeter sized cracks may result in durability problems as particularly connected cracks increase matrix permeability. Ingress water and chemicals can cause premature matrix degradation...journal article 2011
