@article{52802, abstract = {{AbstractCurrently, the fused deposition modeling (FDM) process is the most common additive manufacturing technology. The principle of the FDM process is the strand wise deposition of molten thermoplastic polymers, by feeding a filament trough a heated nozzle. Due to the strand and layer wise deposition the cooling of the manufactured component is not uniform. This leads to dimensional deviations which may cause the component to be unusable for the desired application. In this paper, a method is described which is based on the shrinkage compensation through the adaption of every single raster line in components manufactured with the FDM process. The shrinkage compensation is based on a model resulting from a DOE which considers the main influencing factors on the shrinkage behavior of raster lines in the FDM process. An in‐house developed software analyzes the component and locally applies the shrinkage compensation with consideration of the boundary conditions, e.g., the position of the raster line in the component and the process parameters. Following, a validation using a simple geometry is conducted to show the effect of the presented adaptive scaling method.}}, author = {{Moritzer, Elmar and Hecker, Felix}}, issn = {{1022-1360}}, journal = {{Macromolecular Symposia}}, keywords = {{Materials Chemistry, Polymers and Plastics, Organic Chemistry, Condensed Matter Physics}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Adaptive Scaling of Components in the Fused Deposition Modeling Process}}}, doi = {{10.1002/masy.202200181}}, volume = {{411}}, year = {{2023}}, } @article{29809, author = {{Reitz, A. and Grydin, O. and Schaper, M.}}, issn = {{0921-5093}}, journal = {{Materials Science and Engineering: A}}, keywords = {{Mechanical Engineering, Mechanics of Materials, Condensed Matter Physics, General Materials Science}}, publisher = {{Elsevier BV}}, title = {{{Influence of thermomechanical processing on the microstructural and mechanical properties of steel 22MnB5}}}, doi = {{10.1016/j.msea.2022.142780}}, volume = {{838}}, year = {{2022}}, } @article{30920, abstract = {{Abstract Batteries capable of extreme fast-charging (XFC) are a necessity for the deployment of electric vehicles. Material properties of electrodes and electrolytes along with cell parameters such as stack pressure and temperature have coupled, synergistic, and sometimes deleterious effects on fast-charging performance. We develop a new experimental testbed that allows precise and conformal application of electrode stack pressure. We focus on cell capacity degradation using single-layer pouch cells with graphite anodes, LiNi0.5Mn0.3Co0.2O2 (NMC532) cathodes, and carbonate-based electrolyte. In the tested range (10 – 125 psi), cells cycled at higher pressure show higher capacity and less capacity fading. Additionally, Li plating decreases with increasing pressure as observed with scanning electron microscopy (SEM) and optical imaging. While the loss of Li inventory from Li plating is the largest contributor to capacity fade, electrochemical and SEM examination of the NMC cathodes after XFC experiments show increased secondary particle damage at lower pressure. We infer that the better performance at higher pressure is due to more homogenous reactions of active materials across the electrode and less polarization through the electrode thickness. Our study emphasizes the importance of electrode stack pressure in XFC batteries and highlights its subtle role in cell conditions.}}, author = {{Cao, Chuntian and Steinrück, Hans-Georg and Paul, Partha P and Dunlop, Alison R. and Trask, Stephen E. and Jansen, Andrew and Kasse, Robert M and Thampy, Vivek and Yusuf, Maha and Nelson Weker, Johanna and Shyam, Badri and Subbaraman, Ram and Davis, Kelly and Johnston, Christina M and Takacs, Christopher J and Toney, Michael}}, issn = {{0013-4651}}, journal = {{Journal of The Electrochemical Society}}, keywords = {{Materials Chemistry, Electrochemistry, Surfaces, Coatings and Films, Condensed Matter Physics, Renewable Energy, Sustainability and the Environment, Electronic, Optical and Magnetic Materials}}, pages = {{040540}}, publisher = {{The Electrochemical Society}}, title = {{{Conformal Pressure and Fast-Charging Li-Ion Batteries}}}, doi = {{10.1149/1945-7111/ac653f}}, volume = {{169}}, year = {{2022}}, } @article{32108, author = {{Henksmeier, T. and Schulz, J.F. and Kluth, E. and Feneberg, M. and Goldhahn, R. and Sanchez, A.M. and Voigt, M. and Grundmeier, Guido and Reuter, Dirk}}, issn = {{0022-0248}}, journal = {{Journal of Crystal Growth}}, keywords = {{Materials Chemistry, Inorganic Chemistry, Condensed Matter Physics}}, publisher = {{Elsevier BV}}, title = {{{Remote epitaxy of InxGa1-xAs (0 0 1) on graphene covered GaAs(0 0 1) substrates}}}, doi = {{10.1016/j.jcrysgro.2022.126756}}, volume = {{593}}, year = {{2022}}, } @article{32432, author = {{Yang, Yu and Huang, Jingyuan and Dornbusch, Daniel and Grundmeier, Guido and Fahmy, Karim and Keller, Adrian and Cheung, David L.}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, pages = {{9257–9265}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Effect of Surface Hydrophobicity on the Adsorption of a Pilus-Derived Adhesin-like Peptide}}}, doi = {{10.1021/acs.langmuir.2c01016}}, volume = {{38}}, year = {{2022}}, } @article{34207, abstract = {{AlSi casting alloys combine excellent castability with high strength. Hence, this group of alloys is often used in the automotive sector. The challenge for this application is the brittle character of these alloys which leads to cracks during joint formation when mechanical joining technologies are used. A rise in ductility can be achieved by a considerable increase in the solidification rate which results in grain refinement. High solidification rates can be realized in twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9 (for European Norm - aluminum cast product) is manufactured by the TRC process and analyzed. Subsequently, joining investigations are performed on castings in as-cast and heat-treated condition using the self-piercing riveting process considering the joint formation and the load-bearing capacity. Due to the fine microstructure, the crack initiation can be avoided during joining, while maintaining the joining parameters, especially by specimens in heat treatment conditions. Furthermore, due to the extremely fine microstructure, the load-bearing capacity of the joint can be significantly increased in terms of the maximum load-bearing force and the energy absorbed.}}, author = {{Neuser, Moritz and Kappe, Fabian and Ostermeier, Jakob and Krüger, Jan Tobias and Bobbert, Mathias and Meschut, Gerson and Schaper, Mirko and Grydin, Olexandr}}, issn = {{1438-1656}}, journal = {{Advanced Engineering Materials}}, keywords = {{Condensed Matter Physics, General Materials Science}}, number = {{10}}, publisher = {{Wiley}}, title = {{{Mechanical Properties and Joinability of AlSi9 Alloy Manufactured by Twin‐Roll Casting}}}, doi = {{10.1002/adem.202200874}}, volume = {{24}}, year = {{2022}}, } @article{34648, author = {{Hoppe, Christian and Mitschker, Felix and Mai, Lukas and Liedke, Maciej Oskar and Arcos, Teresa and Awakowicz, Peter and Devi, Anjana and Attallah, Ahmed Gamal and Butterling, Maik and Wagner, Andreas and Grundmeier, Guido}}, issn = {{1612-8850}}, journal = {{Plasma Processes and Polymers}}, keywords = {{Polymers and Plastics, Condensed Matter Physics}}, number = {{4}}, publisher = {{Wiley}}, title = {{{Influence of surface activation on the microporosity of PE‐CVD and PE‐ALD SiO x thin films on PDMS}}}, doi = {{10.1002/ppap.202100174}}, volume = {{19}}, year = {{2022}}, } @article{34650, author = {{Xie, Xiaofan and de los Arcos, Teresa and Grundmeier, Guido}}, issn = {{1612-8850}}, journal = {{Plasma Processes and Polymers}}, keywords = {{Polymers and Plastics, Condensed Matter Physics}}, number = {{11}}, publisher = {{Wiley}}, title = {{{Comparative analysis of hexamethyldisiloxane and hexamethyldisilazane plasma polymer thin films before and after plasma oxidation}}}, doi = {{10.1002/ppap.202200052}}, volume = {{19}}, year = {{2022}}, } @article{31241, author = {{Verma, A.K. and Bopp, F. and Finley, J.J. and Jonas, B. and Zrenner, A. and Reuter, Dirk}}, issn = {{0022-0248}}, journal = {{Journal of Crystal Growth}}, keywords = {{Materials Chemistry, Inorganic Chemistry, Condensed Matter Physics}}, publisher = {{Elsevier BV}}, title = {{{Low Areal Densities of InAs Quantum Dots on GaAs(100) Prepared by Molecular Beam Epitaxy}}}, doi = {{10.1016/j.jcrysgro.2022.126715}}, year = {{2022}}, } @article{33332, author = {{Bopp, Frederik and Rojas, Jonathan and Revenga, Natalia and Riedl, Hubert and Sbresny, Friedrich and Boos, Katarina and Simmet, Tobias and Ahmadi, Arash and Gershoni, David and Kasprzak, Jacek and Ludwig, Arne and Reitzenstein, Stephan and Wieck, Andreas and Reuter, Dirk and Müller, Kai and Finley, Jonathan J.}}, issn = {{2511-9044}}, journal = {{Advanced Quantum Technologies}}, keywords = {{Electrical and Electronic Engineering, Computational Theory and Mathematics, Condensed Matter Physics, Mathematical Physics, Nuclear and High Energy Physics, Electronic, Optical and Magnetic Materials, Statistical and Nonlinear Physics}}, publisher = {{Wiley}}, title = {{{Quantum Dot Molecule Devices with Optical Control of Charge Status and Electronic Control of Coupling}}}, doi = {{10.1002/qute.202200049}}, year = {{2022}}, } @article{33682, author = {{Khazaei, Mohammad and Ranjbar, Ahmad and Kang, Yoon‐Gu and Liang, Yunye and Khaledialidusti, Rasoul and Bae, Soungmin and Raebiger, Hannes and Wang, Vei and Han, Myung Joon and Mizoguchi, Hiroshi and Bahramy, Mohammad S. and Kühne, Thomas and Belosludov, Rodion V. and Ohno, Kaoru and Hosono, Hideo}}, issn = {{1616-301X}}, journal = {{Advanced Functional Materials}}, keywords = {{Electrochemistry, Condensed Matter Physics, Biomaterials, Electronic, Optical and Magnetic Materials}}, number = {{20}}, publisher = {{Wiley}}, title = {{{Electronic Structures of Group III–V Element Haeckelite Compounds: A Novel Family of Semiconductors, Dirac Semimetals, and Topological Insulators}}}, doi = {{10.1002/adfm.202110930}}, volume = {{32}}, year = {{2022}}, } @article{33694, abstract = {{Abstract The round robin test investigated the reliability users can expect for AlSi10Mg additive manufactured specimens by laser powder bed fusion through examining powder quality, process parameter, microstructure defects, strength and fatigue.

By the strict control of temperature and Pd/Au molar ratio and the use of l-ascorbic acid for making both Au cores and Pd shells, a 1.5 nm Pd layer is formed around the Au core, as evidenced by transmission electron microscopy and energy-dispersive spectroscopy. The core@shell structure and the Pd shell remain intact upon deposition onto alumina and after being used for CO oxidation, as revealed by additional X-ray diffraction and X-ray photoemission spectroscopy before and after the reaction. The Pd shell surface was characterized with in situ infrared (IR) spectroscopy using CO as a chemical probe during CO adsorption–desorption. The IR bands for CO ad-species on the Pd shell suggest that the shell exposes mostly low-index surfaces, likely Pd(111) as the majority facet. Generally, the IR bands are blue-shifted as compared to conventional Pd/alumina catalysts, which may be due to the different support materials for Pd, Au versus Al2O3, and/or less strain of the Pd shell. Frequencies obtained from density functional calculations suggest the latter to be significant.
