Mohammadi, V. (author), De Boer, W.B. (author), Nanver, L.K. (author)In this paper, an analytical model is established to describe the deposition kinetics and the deposition chamber characteristics that determine the deposition rates of pure boron (PureB-) layers grown by chemical-vapor deposition (CVD) from diborane (B2H6) as gas source on a non-rotating silicon wafer. The model takes into consideration the...journal article 2012

Janssen, M.F.W.H.A. (author), Charalabidis, Y. (author), Zuiderwijk, A.M.G. (author)Although a significant number of public organizations have embraced the idea of open data, many are still reluctant to do this. One root cause is that the publicizing of data represents a shift from a closed to an open system of governance, which has a significant impact upon the relationships between public agencies and the users of open data....journal article 2012

(author)Nanoporous host materials giving rise to transient guest profiles of cylindrical symmetry during molecular uptake and release are shown to provide particularly advantageous conditions for the study of guest diffusion by micro-imaging. Considering zeolites of structure type DDR (Deca-dodecasil 3R) as a host system and short-chain length...journal article 2012

Kasmire, J. (author), Dijkema, G.P.J. (author), Nikolic, I. (author)Horticulture, a pillar of the Dutch economy, has already achieved remarkable productivity increases through the use of natural gas for heating, lighting and CO2. Further innovative technologies that could aid the transition toward sustainable energy use, including heat/cold storage and deepgeothermal heat sources, are currently in development...conference paper 2012

Rassaei, L. (author), Cui, J. (author), Goluch, E.D. (author), Lemay, S.G. (author)Despite the broad use of enzymes in electroanalytical biosensors, the influence of enzyme kinetics on the function of prototype sensors is often overlooked or neglected. In the present study, we employ amperometry as an alternative or complementary method to study the kinetics of tyrosinase, whose catalytic activity results in o-quinone products...journal article 2012

Van Oven, J.C. (author), Berwald, F. (author), Berggren, K.K. (author), Kruit, P. (author), Hagen, C.W. (author)This paper demonstrates electron-beam-induced deposition of few-nm-width dense features on bulk samples by using a scanning electron-beam lithography system. To optimize the resultant features, three steps were taken: (1) features were exposed in a repetitive sequence, so as to build up the deposited features gradually across the entire pattern,...journal article 2011

Burchard, H. (author), Hetland, R.D. (author), Schulz, E. (author), Schuttelaars, H.M. (author)The generation of residual circulation in a tidally energetic estuary with constant longitudinal salinity gradient and parabolic cross section is examined by means of a two-dimensional cross-sectional numerical model, neglecting river runoff and Stokes drift. It is shown how the longitudinal and lateral residual circulation can be decomposed...journal article 2011

Vreugdenhil, H.S.I. (author)Pilot projects are widely applied in water management. They can be used to test risky innovations at confined scale, but can also be used to delay policy decisions or to advocate a particular innovation. In this book the phenomenon ‘pilot project’ is explored both theoretically and empirically. A framework to analyse pilot projects is developed...doctoral thesis 2010

Van den Bergh, J. (author)Around 2004 the annual energy consumption of the Dutch (petro-)chemical industry was estimated to be 460 PJ of which 200 PJ could be allocated to separation processes [1]. In 2009, 15% of the global energy consumption was required for separation and purification processes to produce commodities. Moreover, it is expected that in 2040 the global...doctoral thesis 2010

Castillo, J.M. (author)The adsorption of water on hydrophobic zeolites such as silicalite and on hydrophilic MOF (metal-organic framework), Cu-BTC, is completely different, as described in chapters 2 and 4. While in hydrophobic materials water adsorption isotherms are very steep and difficult to measure, both experimentally and by simulation, in hydrophilic materials...doctoral thesis 2010

Krishnan, G. (author), Kooi, B.J. (author), Palasantzas, G. (author), Pivak, Y. (author), Dam, B. (author)In this work we present a unique transmission electron microscopy study of the thermal stability of gas phase synthesized Mg nanoparticles, which have attracted strong interest as high capacity hydrogen storage materials. Indeed, Mg nanoparticles with a MgO shell ( ? 3?nm thick) annealed at 300?°C show evaporation, void formation, and void...journal article 2010

Van der Ven, A. (author), Garikipati, K. (author), Kim, S. (author), Wagemaker, M. (author)We investigate the role of coherency strains on the thermodynamics of two-phase coexistence during Li (de)intercalation of LixFePO4. We explicitly account for the anisotropy of the elastic moduli and analytically derive coupled chemical and mechanical equilibrium criteria for two-phase morphologies observed experimentally. Coherent two-phase...journal article 2009

Van Putten, D.S. (author), Kalikmanov, V.I. (author)A new model describing the evolution of clusters in the processes of nucleation and growth is proposed. The diffusion flux in the nonstationary Fokker–Planck equation with an unknown distribution function is approximated by the closed form expression containing the steady-state solution of the Zeldovich–Frenkel equation. This is justified due to...journal article 2009

Singh, S. (author), Eijt, S.W.H. (author)We report ab initio calculations based on density-functional theory, of the vacancy-mediated hydrogen migration energy in bulk NaH and near the NaH(001) surface. The estimated rate of the vacancy mediated hydrogen transport, obtained within a hopping diffusion model, is consistent with the reaction rates of H-D exchange in nano-NaH at the...journal article 2008

For particles that are physically bound to the surrounding chains, light-scattering experiments reveal that the submillisecond dynamics changes from diffusive to Rouse-like upon crossing the network formation threshold. Particles that are not bound do not show...journal article 2008
