In this study, the preparation of novel opal and double-inverse opal films based on thermally treated metallopolymer core particles with a silica shell is described. Thermal treatment leads to the formation of magnetic nanorattle-type particles. The main challenge of artificial particles is to ensure sufficient dispersibility after several synthetic steps. Especially silica particles providing surface hydroxyl groups tend to sinter at high temperatures leading to agglomeration. We present the introduction of trimethyl ethoxy silane (TMES) as an excellent functionalization reagent as the key reaction step. The necessity and success of functionalization are investigated by transmission electron microscopy (TEM) and zeta potential measurements. Importantly, solid state NMR techniques are employed to gain deeper insights into the chemical structure of the surface-attached reagent. Finally, by this convenient functionalization the preparation of elastomeric opal films and double-inverse opal films is proven successful revealing excellent optical film properties. Moreover, magnetic properties of these novel films are investigated by using magnetic force microscopy (MFM). The herein established route is expected to pave the way for the preparation of a variety of advanced and stimuli-responsive optical materials.}}, author = {{Scheid, D. and Stock, D. and Winter, T. and Gutmann, Torsten and Dietz, C. and Gallei, M.}}, issn = {{2050-7526}}, journal = {{Journal of Materials Chemistry C}}, keywords = {{Materials Science, silica, Physics, nmr, colloidal photonic crystals, light, polymerization, solids, structural color, thermo}}, number = {{11}}, pages = {{2187–2196}}, title = {{{The pivotal step of nanoparticle functionalization for the preparation of functional and magnetic hybrid opal films}}}, doi = {{10.1039/c5tc04388c}}, volume = {{4}}, year = {{2016}}, } @article{35332, author = {{Xu, Yang and Laupheimer, Michaela and Preisig, Natalie and Sottmann, Thomas and Schmidt, Claudia and Stubenrauch, Cosima}}, issn = {{0743-7463}}, journal = {{Langmuir}}, keywords = {{Electrochemistry, Spectroscopy, Surfaces and Interfaces, Condensed Matter Physics, General Materials Science}}, number = {{31}}, pages = {{8589--8598}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Gelled Lyotropic Liquid Crystals}}}, doi = {{10.1021/acs.langmuir.5b01992}}, volume = {{31}}, year = {{2015}}, } @article{39688, author = {{Urbanski, Martin and Mirzaei, Javad and Sharma, Anshul and Hofmann, Daniel and Kitzerow, Heinz-Siegfried and Hegmann, Torsten}}, issn = {{0267-8292}}, journal = {{Liquid Crystals}}, keywords = {{Condensed Matter Physics, General Materials Science, General Chemistry}}, number = {{2}}, pages = {{183--194}}, publisher = {{Informa UK Limited}}, title = {{{Chemically and thermally stable, emissive carbon dots as viable alternatives to semiconductor quantum dots for emissive nematic liquid crystal–nanoparticle mixtures with lower threshold voltage}}}, doi = {{10.1080/02678292.2015.1082651}}, volume = {{43}}, year = {{2015}}, } @article{40588, abstract = {{

One of the most important approaches is the implementation of lightweight constructions. Therefore, the usage of high performance materials with tailored properties gains importance. For safety-relevant components such as automotive passenger cells it is necessary to minimize deformation to reduce the risk of injury for the vehicle occupants during a car accident. Thus, hot stamped high-strength steels have been established. High-strength and low formability of this kind of materials represent new challenges for joining technologies. One possibility to join high-strength steels is the newly developed shear-clinching technology. Due to the use of a combined cutting and joining process, the connection of dissimilar materials with high difference in strength and formability can be achieved. Further research to ensure process reliability and to improve the strength of the joint is required. One possible approach for this is the numerical investigation of the material flow during the joining process. Therefore, the definition of process parameters for the finite element model is necessary. A big impact on the quality of the results has the accuracy of the used friction values. As established testing methods are not suitable for modeling the rather complex tribological system between the joining partners of the shear-clinching process, an innovative testing method is needed. Studies in the field of sheet-bulk metal forming already demonstrated the applicability of the ring compression test for sheet metals. This paper presents a concept for the adaption of the ring compression test to the specific needs of the investigated shear-clinching process. The numerical identification of the friction coefficients is validated by experimental data and first results are qualified by experimental and simulative shear-clinching joints.}}, author = {{Müller, Martin and Vierzigmann, Ulrich and Hörhold, Réjane and Meschut, Gerson and Merklein, Marion}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, keywords = {{Mechanical Engineering, Mechanics of Materials, General Materials Science}}, pages = {{469--476}}, publisher = {{Trans Tech Publications, Ltd.}}, title = {{{Development of a Testing Method for the Identification of Friction Coefficients for Numerical Modeling of the Shear-Clinching Process}}}, doi = {{10.4028/www.scientific.net/kem.639.469}}, volume = {{639}}, year = {{2015}}, } @article{40591, abstract = {{

Particularly in the automotive sector, lightweight design principles continue to prosper rapidly. As a result, adjusted materials for different applications were developed. Due to the formation of intermetallic phases, most multi-material mixes cannot be welded and require adapted joining technologies. Mechanical joining technologies such as self-piercing riveting and mechanical clinching have proven effective methods of joining lightweight materials like aluminium and ductile steels. New high-strength steels are increasingly used in crash-sections, where limited deformation under impact load is required. These hot stamped steels have a very low elongation at break and therefore a low formability. Currently there is no joining by forming technology without pre-punching available using these grades of steels on die-side. The newly developed shear-clinching process is one possible method of joining this kind of material without additional elements. The fundamental idea of shear-clinching is a single-stage process in which pre-punching of the die-side material is performed by indirect shear-cutting and subsequent forming of the upper layer into this hole. This would immensely enlarge the application segment of mechanical clinching even if hot stamped steels are positioned on die-side. Fundamental studies are required to ensure process reliability and it is necessary to break down the joining process into fragments, like pre-punching and clinching with pre-punched sheet, and superpose them to form the combined procedure shear-clinching.
