@article{24182, abstract = {{AbstractThis paper presents the results of an interlaboratory study of the rheological properties of cement paste and ultrasound gel as reference substance. The goal was to quantify the comparability and reproducibility of measurements of the Bingham parameters yield stress and plastic viscosity when measured on one specific paste composition and one particular ultrasound gel in different laboratories using different rheometers and measurement geometries. The procedures for both in preparing the cement paste and carrying out the rheological measurements on cement paste and ultrasound gel were carefully defined for all of the study’s participants. Different conversion schemes for comparing the results obtained with the different measurement setups are presented here and critically discussed. The procedure proposed in this paper ensured a reasonable comparability of the results with a coefficient of variation for the yield stress of 27% and for the plastic viscosity of 24%, despite the individual measurement series’ having been performed in different labs with different rheometers and measurement geometries.}}, author = {{Haist, Michael and Link, Julian and Nicia, David and Leinitz, Sarah and Baumert, Christian and von Bronk, Tabea and Cotardo, Dario and Eslami Pirharati, Mahmoud and Fataei, Shirin and Garrecht, Harald and Gehlen, Christoph and Hauschildt, Inga and Ivanova, Irina and Jesinghausen, Steffen and Klein, Christopher and Krauss, Hans-W. and Lohaus, Ludger and Lowke, Dirk and Mazanec, Oliver and Pawelczyk, Sebastian and Pott, Ursula and Radebe, Nonkululeko W. and Riedmiller, Joachim Jürgen and Schmid, Hans-Joachim and Schmidt, Wolfram and Secrieru, Egor and Stephan, Dietmar and Thiedeitz, Mareike and Wilhelm, Manfred and Mechtcherine, Viktor}}, issn = {{1359-5997}}, journal = {{Materials and Structures}}, title = {{{Interlaboratory study on rheological properties of cement pastes and reference substances: comparability of measurements performed with different rheometers and measurement geometries}}}, doi = {{10.1617/s11527-020-01477-w}}, year = {{2020}}, } @article{24183, author = {{Moritzer, Elmar and Wortmann, M. and Sabantina, L. and Klocker, M. and Mirasol, JR}}, journal = {{JOURNAL OF INDUSTRIAL TEXTILES}}, number = {{50}}, pages = {{224--239}}, title = {{{Stabilization of polyacrylonitrile nanofiber mats obtained by needleless electrospinning using dimethyl sulfoxide as solvent}}}, year = {{2020}}, } @article{24184, author = {{Moritzer, Elmar and Mühlhoff, Frederik Marvin and Krampe, Erhard and Lochbaum, Ella}}, journal = {{Plastverarbeiter}}, number = {{07/20}}, pages = {{20--23}}, title = {{{2K-Haftverbunde aus originär inkompatiblen Kunststoffen}}}, year = {{2020}}, } @inproceedings{24201, author = {{Moritzer, Elmar and Kartelmeyer, Stephan and Hüttemann, Vincent }}, booktitle = {{Direct Digital Manufacturing Conference 2020}}, location = {{Berlin}}, title = {{{Additive Manufactured Heat Pipe Injection Mould Element}}}, year = {{2020}}, } @inproceedings{24203, author = {{Moritzer, Elmar and Hillemeyer, Johannes}}, booktitle = {{6.

In this article, we will describe the fundamental design considerations for a hot wall reactor system able to produce oxide nanoparticles. The system is outstanding in its ability to produce mostly spherical nanoparticles at particle sizes of up to 100 nm and even larger at mass outputs in the order of grams per hour by being able to rapidly quench the aerosol. While high production rates or larger particle sizes are already easily obtained with hot wall reactors, it is very challenging to produce these spherical particles at high mass rates. We will show in this research that the temperature and the particle number concentration are the major aspects influencing the particle morphology at the end of the process. Investigation on the performance of the setup shows good control over the temperature and the particle production stability. A representative particle characterization using SEM and scanning mobility particle sizer showed that particles are mostly spherical, while the particle size distribution had a geometric standard deviation close to 1.5. In addition to the aspects mentioned above, a possibility to manipulate the aggregation downstream of the reactor is to be presented as well. We found that applying electrical charges to the aerosol particles (in opposite polarity) can significantly foster aggregation.}}, author = {{Rasche, David B. and Tigges, Lena and Schmid, Hans-Joachim}}, journal = {{Review of Scientific Instruments}}, pages = {{055104}}, publisher = {{AIP Publishing}}, title = {{{An Apparatus to Synthesize Ceramic Nanoparticles with a Precisely Adjusted Temperature History and a Significant Mass Output}}}, doi = {{10.1063/1.5133438}}, volume = {{91}}, year = {{2020}}, }
