Those materials do not always meet the requirements for direct production of functional parts by laser sintering.

During this research a laser sintering test equipment for material qualification has been built up. The forthcomings are an optimized software solution, an innovative optical system, an alternative powder coating system and an improved temperature control.

Combining all-atom molecular dynamics and capillary simulations we demonstrate that the linear scaling of the interparticle forces with the particle diameter, well established for microscopic and macroscopic particles, can be extended down to diameters of a few nm. At this size scale, however, the molecular nature of the water adsorbates dictates the adhesion forces both via solvation effects and influencing parameters of analytical capillary models such as the equilibrium particle–particle separation distance and the water/particle contact angle. Moreover, the water surface tension becomes considerably larger than the macroscopic bulk value due to combined effects of thin-film confinement and tight curvature, in a way that strongly depends on humidity and particle size. Taking these effects into proper account, classical capillary equations can be used to predict the interparticle forces even of the smallest particles considered here (4 nm), although the circular approximation fails to reproduce the distance at which the water meniscus breaks. Finally, the transition between the dominating effects at the nanoscopic scale and conventional capillary theory valid at microscopic size scales can be only rationalized if the presence of roughness asperities on the surface of the large particles is explicitly taken into account.}}, author = {{Laube, Jens and Dörmann, Michael and Schmid, Hans-Joachim and Mädler, Lutz and Colombi Ciacchi, Lucio}}, issn = {{1932-7447}}, journal = {{The Journal of Physical Chemistry C}}, pages = {{15294--15303}}, title = {{{Dependencies of the Adhesion Forces between TiO2 Nanoparticles on Size and Ambient Humidity}}}, doi = {{10.1021/acs.jpcc.7b05655}}, year = {{2017}}, } @article{26107, abstract = {{Capillary forces are very important considering the handling of powders as they, in general, exceed other adhesion forces. These capillary forces are dependent on several different parameters. Especially the distance between the particles is an important parameter. For example, in moving bulk solids a large variety of distances between particles will occur. Therefore, the distance-dependence of capillary bridges was investigated with a numerical simulation method, assuming thermodynamic equilibrium which is attained very fast for small particles. This method uses the Kelvin equation and the Young-Laplace equation to calculate numerically the shape of the capillary bridge without any assumption regarding the shape. The force is eventually derived from the meniscus shape. The distance becomes extremely important when the capillary liquid bridge between two surfaces is only determined by capillary condensation depending on relative humidity. Only a slight increase of the distance within the fraction of a nanometer changes the behaviour of the capillary force significantly. Furthermore, the influence of the force on the separation of particles will be presented. The force decreases almost linearly with increasing distance for a wide range of distances and consequently, a contact stiffness for capillary bridges could be derived. These results may e.g. be used in DEM models. Also, the maximum separation distance of capillary bridges in thermodynamic equilibrium and the correlation with the according bridge volume was investigated. As two limiting cases for capillary bridges at varying distances one can assume either a constant curvature, i.e. infinitely fast attainment of equilibrium, or a constant volume, i.e. infinitely slow attainment of equilibrium. Therefore, a comparison of these two possibilities will be presented and discussed as well.}}, author = {{Dörmann, Michael and Schmid, Hans-Joachim}}, issn = {{0032-5910}}, journal = {{Powder Technology}}, pages = {{175--183}}, title = {{{Distance-dependency of capillary bridges in thermodynamic equilibrium}}}, doi = {{10.1016/j.powtec.2017.01.012}}, year = {{2017}}, } @inbook{2619, author = {{Betz, Stefan}}, booktitle = {{Aktuelle Fragestellungen zu Produktion, Logistik und Controlling}}, editor = {{Betz, Stefan}}, pages = {{85--111}}, title = {{{Strategische Erfolgsplanung für Produktinnovationen}}}, year = {{2017}}, } @inbook{2620, author = {{Betz, Stefan}}, booktitle = {{Aktuelle Fragestellungen zu Produktion, Logistik und Controlling}}, editor = {{Betz, Stefan}}, pages = {{299--328}}, title = {{{Lagerkapazitätsdimensionierung als betriebswirtschaftliches Entscheidungsproblem}}}, year = {{2017}}, } @phdthesis{26246, author = {{Iwanek, Peter}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Systematik zur Steigerung der Intelligenz mechatronischer Systeme im Maschinen- und Anlagenbau}}}, volume = {{366}}, year = {{2017}}, } @phdthesis{26247, author = {{Schierbaum, Thomas}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Systematik zur Kostenbewertung im Systementwurf mechatronischer Systeme in der Technologie Molded Interconnect Devices (MID)}}}, volume = {{368}}, year = {{2017}}, } @phdthesis{26248, author = {{Westermann, Thorsten}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Systematik zur Reifegradmodell-basierten Planung von Cyber-Physical Systems des Maschinen- und Anlagenbaus}}}, volume = {{375}}, year = {{2017}}, } @article{26307, author = {{Sperling, Jan and Walmsley, I. A.}}, issn = {{0031-9007}}, journal = {{Physical Review Letters}}, title = {{{Separable and Inseparable Quantum Trajectories}}}, doi = {{10.1103/physrevlett.119.170401}}, year = {{2017}}, } @article{26308, author = {{Kröger, Johannes and Ahrens, Thomas and Sperling, Jan and Vogel, Werner and Stolz, Heinrich and Hage, Boris}}, issn = {{0953-4075}}, journal = {{Journal of Physics B: Atomic, Molecular and Optical Physics}}, title = {{{High intensity click statistics from a 10 × 10 avalanche photodiode array}}}, doi = {{10.1088/1361-6455/aa8e68}}, year = {{2017}}, } @article{26309, author = {{Sperling, Jan and Perez-Leija, Armando and Busch, Kurt and Walmsley, Ian A.}}, issn = {{2469-9926}}, journal = {{Physical Review A}}, title = {{{Quantum coherences of indistinguishable particles}}}, doi = {{10.1103/physreva.96.032334}}, year = {{2017}}, } @article{26310, author = {{Agudelo, E. and Sperling, Jan and Costanzo, L. S. and Bellini, M. and Zavatta, A. and Vogel, W.}}, issn = {{0031-9007}}, journal = {{Physical Review Letters}}, title = {{{Conditional Hybrid Nonclassicality}}}, doi = {{10.1103/physrevlett.119.120403}}, year = {{2017}}, } @article{26311, author = {{Kühn, B. and Vogel, W. and Sperling, Jan}}, issn = {{2469-9926}}, journal = {{Physical Review A}}, title = {{{Displaced photon-number entanglement tests}}}, doi = {{10.1103/physreva.96.032306}}, year = {{2017}}, } @article{26312, author = {{Bohmann, M. and Sperling, Jan and Vogel, W.}}, issn = {{2469-9926}}, journal = {{Physical Review A}}, title = {{{Entanglement verification of noisy NOON states}}}, doi = {{10.1103/physreva.96.012321}}, year = {{2017}}, } @article{26313, author = {{Sperling, Jan and Eckstein, A. and Clements, W.
