A well-defined manipulation of atomization may be achieved by variation of nozzle geometry, injection parameter or fluid properties. However, change of fluid properties, e.g. varying solvents or increasing the precursor concentration, also influences the final particle properties. In this work, the influence of precursor concentration on fluid properties, spray and particle formation in Flame Spray Pyrolysis is experimentally investigated. High-speed shadowgraphy and Phase-Doppler measurements are conducted in a semi-closed combustion chamber with a well-defined burner geometry (SpraySyn burner) that is based on a coaxial atomization principle. By adding precursor to the flammable solvent, resulting spray characteristics, flame shape and appearance are changed in color, shape and mean droplet size distribution. Compared to resulting mean droplet sizes of pure solvent mixtures (D32, 22 μm), mean droplet sizes in the center of the precursor flame at 30 mm above the burner are generally smaller (D32, 18 μm). Persisting high share of small droplets in the droplet size distribution are presented, that presumably origin from an accumulation of metal organic precursor at the droplet surface during combustion, that acts as a diffusive barrier for high volatility solvent and thus reduces droplet evaporation. Sufficiently high above the nozzle exit, increasing the precursor concentration does not affect the radial distribution of mean droplet sizes but leads to increased mean particle sizes. More precursor presumably leads to higher concentrations of prime particles in the flame, thus probability of particle collusion and agglomeration. High-speed imaging at nozzle exit revealed random fluctuations of initial jet diameter, paired with jet axis shifting around 1000 Hz. These superposed fluctuations determine the initial conditions for atomization, induce pulsations in the flame and thus initiate the entire chain of the particle synthesis process.}}, author = {{Bieber, M. and Tischendorf, R. and Reddemann, M. and Schmid, H.-J. and Kneer, R.}}, keywords = {{FSP, nanoparticle synthesis, in situ measurements}}, location = {{Paris}}, publisher = {{ILASS (European Conference on Liquid Atomization and Spray Systems)}}, title = {{{Influence of precursor concentration on spray and particle formation in flame spray pyrolysis}}}, year = {{2019}}, } @techreport{24628, author = {{Menge, Dennis and Walter, Rolf and Schmid, Hans-Joachim and Breuer, Ulf Paul}}, pages = {{77}}, title = {{{FVA-Nr. 813 I - Generative Verfahren zur Herstellung von Polymerbauteilen}}}, volume = {{1338}}, year = {{2019}}, } @article{24632, abstract = {{Prerequisite for an efficient cooling energy system is the knowledge and optimal combination of different operating conditions of individual compression and free cooling chillers.

This study applied a predictive optimization algorithm to calculate the optimal operating conditions of multiple chillers. A sprinkler tank offers the opportunity to store cold-water for later utilization. This potential is used to show the load shifting potential of the cooling system by using a variable electricity price as an input variable to the optimization. The set points from the optimization have been continuously adjusted throughout a dynamic simulation.

However, the adsorbed water structure and thus the capillary bridge formation is influenced by various parameters like the particle morphology (e.g. particle size, roughness) as well as the surface chemistry (surface energy, adsorbate structure) and therefore needs to be analyzed on a submicroscopic or even molecular basis. A multi-scale approach ranging from experiments on an individual particle level (AFM and liquid bridge simulation) and investigations on small particle ensembles (combined QCM-D/FTIR) up to macroscopic description of bulk behavior is presented in this chapter. In this context, the combined in situ QCM-D/FTIR experiments are bridging the gap between experiments on an individual particle level and macroscopic bulk behavior. Variation of surface chemistry by means of adsorption of functional organic molecules allows for the correlation of macroscopic particle behavior to nanoscopic effects like the presence and structure of adsorbate layers as well as the formation of capillary bridges while keeping the disperse properties constant. Besides extensive experimental work, simulations of capillary bridges formed by condensation from humid air are presented. It is clearly shown that well known approximations which have been introduced for micron-sized particles are not valid any more for nano-scaled particles. The forces between nanoparticles by static liquid bridges and their dependency on particle size, contact angle, humidity and interparticle distance are discussed in detail. Furthermore, capillary forces during separation of particles are studied thoroughly and a constitutive law based on a contact stiffness allows the transfer to DEM simulations of wet powders. Finally, it is demonstrated by comparison to Molecular Dynamics simulations, that the used continuum approach to simulate capillary bridges might even be used down to particle sizes of a few nanometers, if some additional effects are considered correctly.}}, author = {{Schmid, Hans-Joachim and Grundmeier, Guido and Dörmann, Michael and Orive, Alejandro González and de los Arcos, Teresa and Torun, Boray}}, booktitle = {{Particles in Contact}}, title = {{{Understanding and Manipulation of Nanoparticle Contact Forces by Capillary Bridges}}}, doi = {{10.1007/978-3-030-15899-6_2}}, year = {{2019}}, } @article{26224, author = {{Santandrea, Matteo and Stefszky, Michael and Roeland, Ganaël and Silberhorn, Christine}}, issn = {{1367-2630}}, journal = {{New Journal of Physics}}, title = {{{Characterisation of fabrication inhomogeneities in Ti:LiNbO3 waveguides}}}, doi = {{10.1088/1367-2630/ab5cb5}}, year = {{2019}}, } @article{26225, author = {{Santandrea, Matteo and Stefszky, Michael and Silberhorn, Christine}}, issn = {{0146-9592}}, journal = {{Optics Letters}}, title = {{{General framework for the analysis of imperfections in nonlinear systems}}}, doi = {{10.1364/ol.44.005398}}, year = {{2019}}, } @article{26226, author = {{Santandrea, Matteo and Stefszky, Michael and Ansari, Vahid and Silberhorn, Christine}}, issn = {{1367-2630}}, journal = {{New Journal of Physics}}, title = {{{Fabrication limits of waveguides in nonlinear crystals and their impact on quantum optics applications}}}, doi = {{10.1088/1367-2630/aaff13}}, year = {{2019}}, } @article{26237, author = {{Luo, Kai-Hong and Ansari, Vahid and Massaro, Marcello and Santandrea, Matteo and Eigner, Christof and Ricken, Raimund and Herrmann, Harald and Silberhorn, Christine}}, issn = {{1094-4087}}, journal = {{Optics Express}}, title = {{{Counter-propagating photon pair generation in a nonlinear waveguide}}}, doi = {{10.1364/oe.378789}}, year = {{2019}}, } @article{26293, author = {{Sperling, Jan and Vogel, W}}, issn = {{0031-8949}}, journal = {{Physica Scripta}}, title = {{{Quasiprobability distributions for quantum-optical coherence and beyond}}}, doi = {{10.1088/1402-4896/ab5501}}, year = {{2019}}, } @article{26297, author = {{Cimini, Valeria and Gianani, Ilaria and Sbroscia, Marco and Sperling, Jan and Barbieri, Marco}}, issn = {{2643-1564}}, journal = {{Physical Review Research}}, title = {{{Measuring coherence of quantum measurements}}}, doi = {{10.1103/physrevresearch.1.033020}}, year = {{2019}}, } @article{26298, author = {{Rezai, Mohammad and Sperling, Jan and Gerhardt, Ilja}}, issn = {{2058-9565}}, journal = {{Quantum Science and Technology}}, title = {{{What can single photons do what lasers cannot do?}}}, doi = {{10.1088/2058-9565/ab3d56}}, year = {{2019}}, } @article{26299, author = {{Phillips, D.

Objective The aim of this network meta-analysis (NMA) was to assess how isocaloric substitutions of dietary sugar with other carbohydrates affect cardiometabolic risk factors, comparing different intervention studies. Methods We included randomized controlled trials (RCTs) investigating the isocaloric effect of substituting dietary sugars (fructose, glucose, sucrose) with other sugars or starch on cardiometabolic risk markers, including LDL cholesterol, triacylglycerol (TG), fasting glucose (FG), glycated hemoglobin (HbA1c), insulin resistance (HOMA-IR), uric acid, C-reactive protein (CRP), alanine transaminase (ALT), aspartate transaminase (AST), and liver fat content. To identify the most beneficial intervention for each outcome, random-effects NMA was conducted by calculating pooled mean differences (MDs) with 95% CIs, and by ranking the surface under the cumulative ranking curves (SUCRAs). The certainty of evidence was evaluated using the Confidence In Network Meta-Analysis tool. Results Thirty-eight RCTs, including 1383 participants, were identified. A reduction in LDL-cholesterol concentrations was shown for the exchange of sucrose with starch (MD: −0.23 mmol/L; 95% CI: −0.38, −0.07 mmol/L) or fructose with starch (MD: −0.22 mmol/L; 95% CI: −0.39, −0.05 mmol/L; SUCRAstarch: 98%). FG concentrations were also lower for the exchange of sucrose with starch (MD: −0.14 mmol/L; 95% CI: −0.29, 0.01 mmol/L; SUCRAstarch: 91%). Replacing fructose with an equivalent energy amount of glucose reduced HOMA-IR (MD: −0.36; 95% CI: −0.71, −0.02; SUCRAglucose: 74%) and uric acid (MD: −23.77 µmol/L; 95% CI: −44.21, −3.32 µmol/L; SUCRAglucose: 93%). The certainty of evidence was rated very low to moderate. No significant effects were observed for TG, HbA1c, CRP, ALT, and AST. Conclusions Our findings indicate that substitution of sucrose and fructose with starch yielded lower LDL cholesterol. Insulin resistance and uric acid concentrations were beneficially affected by replacement of fructose with glucose. Our findings are limited by the very low to moderate certainty of evidence.

Studies comprehensively and bidirectionally probing possible causal links between such blood constituents and liability to schizophrenia are lacking. Methods To disentangle putative causal links between CRP blood levels and schizophrenia in both directions, we conducted multiple univariable Mendelian-randomization (MR) analyses, ranging from fixed-effect to inverse variance-weighted (IVW), weighted-median, MR Egger and generalized summary-data-based Mendelian-randomization (GSMR) models. To prioritize metabolic risk factors for schizophrenia, a novel multivariable approach was applied: multivariable Mendelian-randomization–Bayesian model averaging (MR-BMA). Results All forward univariable MR analyses consistently showed that CRP has a protective effect on schizophrenia, whereas reverse MR analyses consistently suggested absent causal effects of schizophrenia liability on CRP blood levels. Using MR-BMA, as the top protective factors for schizophrenia we prioritized leucine and as the prime risk-factor triglycerides in medium very-low-density lipoprotein (VLDL). The five best-performing MR-BMA models provided one additional risk factor: triglycerides in large VLDL; and two additional protective factors: citrate and lactate. Conclusions Our results add to a growing body of literature hinting at metabolic changes—in particular of triglycerides—independently of medication status in schizophrenia. We also highlight the absent effects of genetic liability to schizophrenia on CRP levels. }}, author = {{Lin, Bochao D and Alkema, Anne and Peters, Triinu and Zinkstok, Janneke and Libuda, Lars and Hebebrand, Johannes and Antel, Jochen and Hinney, Anke and Cahn, Wiepke and Adan, Roger and Luykx, Jurjen J}}, issn = {{0300-5771}}, journal = {{International Journal of Epidemiology}}, pages = {{1505--1514}}, title = {{{Assessing causal links between metabolic traits, inflammation and schizophrenia: a univariable and multivariable, bidirectional Mendelian-randomization study}}}, doi = {{10.1093/ije/dyz176}}, year = {{2019}}, } @article{27024, author = {{Kalhoff, Hermann and Mesch, Christina M. and Stimming, Madlen and Israel, Andreas and Spitzer, Christoph and Beganovic, Latifa and Perez, Rocio Estella and Koletzko, Berthold and Warschburger, Petra and Kersting, Mathilde and Libuda, Lars}}, issn = {{0954-3007}}, journal = {{European Journal of Clinical Nutrition}}, pages = {{682--690}}, title = {{{Effects of LC-PUFA supply via complementary food on infant development—a food based intervention (RCT) embedded in a total diet concept}}}, doi = {{10.1038/s41430-019-0491-0}}, year = {{2019}}, } @inproceedings{27101, author = {{Drewel, Marvin and Gausemeier, Jürgen and Vaßholz, Mareen and Homburg, Nils}}, booktitle = {{Symposium für Vorausschau und Technologieplanung, Band 15}}, editor = {{Gausemeier, Jürgen and Bauer, Wilhelm and Dumitrescu, Roman}}, publisher = {{Heinz Nixdorf Institut}}, title = {{{Einstieg in die Plattformökonomie}}}, year = {{2019}}, } @article{27102, abstract = {{Mithilfe von Industrie 4.0-Reifegradmodellen können Unternehmen ihren Leistungsstand im Kontext Industrie 4.0 systematisch erfassen.

Dietary glycemic index (GI) and glycemic load (GL) have been examined in relation to the risk of T2D in multiple prospective cohort studies. Previous meta-analyses indicate significant relations but consideration of causality has been minimal. Here, the results of our recent meta-analyses of prospective cohort studies of 4 to 26-y follow-up are interpreted in the context of the nine Bradford-Hill criteria for causality, that is: (1) Strength of Association, (2) Consistency, (3) Specificity, (4) Temporality, (5) Biological Gradient, (6) Plausibility, (7) Experimental evidence, (8) Analogy, and (9) Coherence. These criteria necessitated referral to a body of literature wider than prospective cohort studies alone, especially in criteria 6 to 9. In this analysis, all nine of the Hill’s criteria were met for GI and GL indicating that we can be confident of a role for GI and GL as causal factors contributing to incident T2D. In addition, neither dietary fiber nor cereal fiber nor wholegrain were found to be reliable or effective surrogate measures of GI or GL. Finally, our cost–benefit analysis suggests food and nutrition advice favors lower GI or GL and would produce significant potential cost savings in national healthcare budgets.
