Therefore it is important to monitor these air pollutants in the cities. In this study an octocopter UAV is used as a carrier for measurement systems for UFPs, fine particulate matter and soot.

The SMPS measured the particle number concentration as well as the particle number size distribution in a range from 5 nm to 350 nm. This was done as a quality assurance for the use of these portable devices for other measurement campaigns for detecting the particle number concentration in mobile applications by e.g. unmanned aerial systems, bicycles, or small aircraft. The results show a good correlation between all the systems. The agreement between the reference system and the NanoCheck was really good, but lower between the DiSCMini and the reference system. Due to the good correlation the data could be post processed with a correction function to reduce the deviation.

No official explanation of this discrepancy exists apart from the definition of the ash cloud boundary. Papers on simulation of the Eyjafjallaj{\"o}kull ash cloud in peer reviewed journals, typically attempted to simulate the VAAC predictions rather than focusing on the satellite pictures. Sporadic measurements made in-situ showed much lower ash concentrations over Europe than the predicted values. Two of the weak points in ash cloud prediction have been studied in airborne measurements of volcanic ash by the Universities in Kyoto Japan, Iceland and D{\"u}sseldorf Germany of eruptions in Sakurajima, Japan. It turns out that gravitational deformation of the plume and a streak fallout process make estimated ash content of clouds larger than the actual, both features are not included in the simulation model. Tropospheric plumes tend to ride in stable inversions this causes gravitational flattening (pancaking) of the volcanic plume, while diffusion in the mixing layer is insignificant. New rules from ICAO, effective from November 2014, reiterate that jetliners should avoid visible ash, this makes information on visible ash important. A procedure developed by JMA′s Tokyo VAAC uses satellite images of visible ash to correct the prediction. This and the fact that meteorological data necessary to model gravitational dispersion and streak fallout do not exist in the international database available to the VAAC′s. This shows that close monitoring by airborne measurements and satellite and other photographic surveillance is necessary.}, subject = {Vulkanismus}, language = {en} } @inproceedings{WeberHewelingFischeretal.2017, author = {Weber, Konradin and Heweling, Georg and Fischer, Christian and Lange, Martin and B{\"o}hlke, Christoph}, title = {Octocopter investigation of the vertical and horizontal variation of ultrafine particles, fine particulate matter and soot in the traffic plume emitted from a Rhine river bridge in Duesseldorf, Germany}, series = {Geophysical Research Abstracts: EGU General Assembly 2017}, volume = {19}, booktitle = {Geophysical Research Abstracts: EGU General Assembly 2017}, publisher = {Copernicus}, address = {G{\"o}ttingen}, year = {2017}, abstract = {For this study an octocopter UAV was used for carrying an ultrafine (UFP) particle monitor, an optical particle counter (OPC) and a micro aethalometer.

For this reason, to overcome this drawback, mobile measurements of the variability of gases (such as O3, NO, NO2) and particulate matter concentration were carried out during this study using an instrumented car. This car was able to deliver measurement results of all these compounds in a large area. The experimental results in this work demonstrate a large spatial variability of gases and fine particulate matters mainly depended on the traffic density and the location.

For the investigations the measurement truck of the laboratory for environmental measurement techniques of the HSD was equipped with different measurement devices for gaseous and aerosol species as well as meteorological sensors. The measurement truck was placed next to a stationary air quality measurement container of the Environmental State Agency of North-Rhine-Westphalia (LANUV). The measurement site is located at the Cornelius street, a direct north south connecting street through the city of Duesseldorf, which is highly frequented by road traffic with an daily amount of about 45,000 vehicles. The street is located within the low emission zone (LEZ). Additionally the pass through of vehicles with a higher weight than 7.5 tons is prohibited. Within this study over a period of several weeks the particle mass concentrations PM10, PM2.5 and PM1, and the particle number size distribution (PNSD) were measured over a broad range from 5 nm to 32 µm with a high temporal resolution. Additionally, an aethalometer was used to determine the proportion of black carbon in the particle ensembles. Gaseous pollutants like nitrogen dioxide, ozone and sulphur dioxide were measured as well. Nitrogen dioxide is a typical species originating from combustion processes. In this study the data from NO2 strongly correlate with ultrafine particle and black carbon concentrations and for this reason all three species are clearly influenced by road traffic. However, this effect is not so pronounced for the particle mass concentrations, which are additionally influenced by the varying local background concentrations. During the measurements, the averaged concentration for PM10 was on a moderate level at 20.6 µg/m³ (PM2.5 13.4 µg/m³, PM1 10.7 µg/m³). The averaged NO2 concentration was 54.2 µg/m³ during the measurement period, which is above the yearly limit value of 40 µg/m³. However, the hourly limit value of 200 µg/m³ was not exceeded during the measurement period of this study. The averaged particle number concentration (PNC5-250 nm) and black carbon concentration were on a low level compared with values from other studies at roadsides. The PNC5-250 nm was at 6,400 \#/cm³ and for black carbon at 1.8 µg/m³. The lower values for PNC and BC are possibly explained as a result due to the measures from the clean air plan. The measurements of this study took place in summertime. The air pollution concentrations might be higher during colder times of the year due to domestic fuel burning. After all it can be stated, that the additional monitoring of ultrafine particles and black carbon is relevant and important to characterize the composition of the air quality at roadsides and offer a better understanding for the temporal resolution of air pollutants in cities.

Besides isoprene, monoterpenes are the non-methane volatile organic compounds (VOCs) with the highest global emission rates. Due to their high reactivity towards OH, monoterpenes can dominate the radical chemistry of the atmosphere in forested areas. In the present study the photochemical degradation mechanism of β-pinene was investigated in the J{\"u}lich atmosphere simulation chamber SAPHIR (Simulation of Atmospheric PHotochemistry In a large Reaction Chamber). One focus of this study is on the OH budget in the degradation process. Therefore, the SAPHIR chamber was equipped with instrumentation to measure radicals (OH, HO2, RO2), the total OH reactivity, important OH precursors (O3, HONO, HCHO), the parent VOC β-pinene, its main oxidation products, acetone and nopinone and photolysis frequencies. All experiments were carried out under low-NO conditions ( ≤  300 ppt) and at atmospheric β-pinene concentrations ( ≤  5 ppb) with and without addition of ozone. For the investigation of the OH budget, the OH production and destruction rates were calculated from measured quantities. Within the limits of accuracy of the instruments, the OH budget was balanced in all β-pinene oxidation experiments. However, even though the OH budget was closed, simulation results from the Master Chemical Mechanism (MCM) 3.2 showed that the OH production and destruction rates were underestimated by the model. The measured OH and HO2 concentrations were underestimated by up to a factor of 2, whereas the total OH reactivity was slightly overestimated because the model predicted a nopinone mixing ratio which was 3 times higher than measured. A new, theory-derived, first-generation product distribution by Vereecken and Peeters (2012) was able to reproduce the measured nopinone time series and the total OH reactivity. Nevertheless, the measured OH and HO2 concentrations remained underestimated by the numerical simulations. These observations together with the fact that the measured OH budget was closed suggest the existence of unaccounted sources of HO2. Although the mechanism of additional HO2 formation could not be resolved, our model studies suggest that an activated alkoxy radical intermediate proposed in the model of Vereecken and Peeters (2012) generates HO2 in a new pathway, whose importance has been underestimated so far. The proposed reaction path involves unimolecular rearrangement and decomposition reactions and photolysis of dicarbonyl products, yielding additional HO2 and CO. Further experiments and quantum chemical calculations have to be made to completely unravel the pathway of HO2 formation.}, language = {en} } @misc{WalserThelokeNehretal.2017, author = {Walser, Sandra M. and Theloke, Jochen and Nehr, Sascha and Brenner, Bernhard and Herr, Caroline E.

The structure and composition of the material was characterized via powder X-ray diffraction (PXRD), M{\"o}ssbauer spectroscopy (MB), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and energy dispersive X-ray spectroscopy (EDX). Two preparation methods of pentlandite bulk electrodes are presented. In the first approach a piece of synthetic pentlandite rock is directly contacted via a wire ferrule. The second approach utilizes pentlandite pellets, pressed from finely ground powder, which is immobilized in a Teflon casing. Both electrodes, whilst being prepared by an additive-free method, reveal high durability during electrocatalytic conversions in comparison to common drop-coating methods. We herein showcase the striking performance of such electrodes to accomplish the hydrogen evolution reaction (HER) and present a standardized method to evaluate the electrocatalytic performance by electrochemical and gas chromatographic methods. Furthermore, we report stability tests via potentiostatic methods at an overpotential of 0.6 V to explore the material limitations of the electrodes during electrolysis under industrial relevant conditions.}, language = {en} } @article{EngelKaluzaOezaslanetal.2017, author = {Engel, Rebecca V. and Kaluza, Stefan and Oezaslan, Mehtap and Peitz, Stephan}, title = {German Catalysis Meeting - 50 Years and as Young as Ever}, series = {ChemCatChem}, volume = {9}, journal = {ChemCatChem}, number = {11}, publisher = {Wiley}, issn = {1867-3899}, doi = {10.1002/cctc.201700683}, pages = {2018 -- 2020}, year = {2017}, language = {en} } @article{DehmerKutzeraNiemann2017, author = {Dehmer, Joanna and Kutzera, Ana-Alicia and Niemann, J{\"o}rg}, title = {Digitalisierung von Gesch{\"a}ftsmodellen durch plattformbasiertes Value Chain Management}, series = {zwf - Zeitschrift f{\"u}r wirtschaftlichen Fabrikbetrieb}, volume = {112}, journal = {zwf - Zeitschrift f{\"u}r wirtschaftlichen Fabrikbetrieb}, number = {4}, publisher = {Hanser}, issn = {0947-0085}, doi = {10.3139/104.111697}, pages = {253 -- 256}, year = {2017}, language = {de} } @article{ZanderRuessBogetal.2017, author = {Zander, Nils and Ruess, Martin and Bog, Tino and Kollmannsberger, Stefan and Rank, Ernst}, title = {Multi-level hp -adaptivity for cohesive fracture modeling}, series = {International Journal for Numerical Methods in Engineering}, volume = {109}, journal = {International Journal for Numerical Methods in Engineering}, number = {13}, publisher = {Wiley}, issn = {1097-0207}, doi = {10.1002/nme.5340}, pages = {1723 -- 1755}, year = {2017}, language = {en} } @article{NguyenStoterBaumetal.2017, author = {Nguyen, Lam H. and Stoter, Stein K.F. and Baum, Thomas and Kirschke, Jan and Ruess, Martin and Yosibash, Zohar and Schillinger, Dominik}, title = {Phase-field boundary conditions for the voxel finite cell method: Surface-free stress analysis of CT-based bone structures}, series = {International Journal for Numerical Methods in Biomedical Engineering}, volume = {33}, journal = {International Journal for Numerical Methods in Biomedical Engineering}, number = {12}, publisher = {Wiley}, issn = {2040-7947}, doi = {10.1002/cnm.2880}, year = {2017}, language = {en} } @article{KeshavanarayanaRuessdeBorst2017, author = {Keshavanarayana, Pradeep and Ruess, Martin and de Borst, Ren{\´e}}, title = {A feedback-loop extended stress fiber growth model with focal adhesion formation}, series = {International Journal of Solids and Structures}, volume = {128}, journal = {International Journal of Solids and Structures}, publisher = {Elsevier}, issn = {0020-7683}, doi = {10.1016/j.ijsolstr.2017.08.023}, pages = {160 -- 173}, year = {2017}, language = {en} } @article{GuoRuessSchillinger2017, author = {Guo, Yujie and Ruess, Martin and Schillinger, Dominik}, title = {A parameter-free variational coupling approach for trimmed isogeometric thin shells}, series = {Computational Mechanics}, volume = {59}, journal = {Computational Mechanics}, number = {4}, publisher = {Springer}, issn = {1432-0924}, doi = {10.1007/s00466-016-1368-x}, pages = {693 -- 715}, year = {2017}, language = {en} } @article{GroenLangelaarSigmundetal.2017, author = {Groen, Jeroen P. and Langelaar, Matthijs and Sigmund, Ole and Ruess, Martin}, title = {Higher-order multi-resolution topology optimization using the finite cell method}, series = {International Journal for Numerical Methods in Engineering}, volume = {110}, journal = {International Journal for Numerical Methods in Engineering}, number = {10}, publisher = {Wiley}, issn = {1097-0207}, doi = {10.1002/nme.5432}, pages = {903 -- 920}, year = {2017}, language = {en} } @article{BiedermannChongKameieretal.2017, author = {Biedermann, Till M. and Chong, Tze Pei and Kameier, Frank and Paschereit, Christian O.}, title = {Statistical-Empirical Modeling of Airfoil Noise Subjected to Leading-Edge Serrations}, series = {AIAA Journal}, volume = {55}, journal = {AIAA Journal}, number = {9}, publisher = {ARC}, doi = {10.2514/1.j055633}, pages = {3128 -- 3142}, year = {2017}, language = {en} } @inproceedings{ZielkeNeefFussenecker2017, author = {Zielke, Thomas and Neef, Matthias and Fussenecker, Claudia}, title = {Teaching Engineering Conferences}, series = {Proceedings of the Canadian Engineering Education Association (CEEA) Conference}, booktitle = {Proceedings of the Canadian Engineering Education Association (CEEA) Conference}, address = {Winnipeg}, organization = {Canadian Engineering Education Association (CEEA)}, year = {2017}, abstract = {This article is on a university course called Engineering Conferences.

They study Mechanical Engineering, Simulation and Experimental Technology, or International Business Engineering. The basic idea of the course concept goes far beyond simply teaching the standards of academic writing and skills for using scientific publications. By using a learnercentered approach, the students get engaged in typical activities around an active attendance of a real conference. Students learn to locate the field of their bachelor thesis or project report in the world of research communities, scientific journals and engineering conferences. They learn about conferences matching their bachelor/project topic. They write a paper complying with common academic standards, submit it to a mock-up conference, and review submissions of their fellow students. Students also produce a poster and have to defend it in a poster session held publicly on the campus.
