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{52207, author = {{Schlüter, Alexander and Rosano, Michele B.}}, issn = {{0959-6526}}, journal = {{Journal of Cleaner Production}}, keywords = {{Industrial and Manufacturing Engineering, Strategy and Management, General Environmental Science, Renewable Energy, Sustainability and the Environment}}, pages = {{19--28}}, publisher = {{Elsevier BV}}, title = {{{A holistic approach to energy efficiency assessment in plastic processing}}}, doi = {{10.1016/j.jclepro.2016.01.037}}, volume = {{118}}, year = {{2016}}, } @article{23750, author = {{Savelsbergh, Elwin R. and Prins, Gjalt T. and Rietbergen, Charlotte and Fechner, Sabine and Vaessen, Bram E. and Draijer, Jael M. and Bakker, Arthur}}, issn = {{1747-938X}}, journal = {{Educational Research Review}}, keywords = {{innovation, STEM education, science education, attitudes}}, pages = {{158--172}}, title = {{{Effects of innovative science and mathematics teaching on student attitudes and achievement: A meta-analytic study}}}, doi = {{10.1016/j.edurev.2016.07.003}}, volume = {{19}}, 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{47910, abstract = {{ The debate surrounding climate change often centers on companies’ contributions to global warming, which has led to an increase in the importance of carbon disclosure.

In practice, service companies offer elevated status to some customers who do not meet the required spending level, in an attempt to profit from the profound allure of status. Relying on social psychology research and a mixed-method approach, this study analyzes the loyalty impact of status endowments, defined as awards of elevated status to customers who are not entitled to it. An exploratory qualitative study identifies customer gratitude and customer skepticism as positive and negative mediators, respectively, of customers’ attitudinal responses to endowed status. Quantitative studies—two experimental and one survey—substantiate these bright and dark sides of endowed status. The efficacy of status endowment is contingent on the context. To alleviate the dark-side effect, managers can allow target customers to actively choose whether to be endowed, especially those who are close to achieving the status already, and provide valuable preferential treatment to customers elevated by either endowment or achievement. These insights offer guidelines for whether and how to use status endowment in hierarchical loyalty programs. }}, author = {{Eggert, Andreas and Steinhoff, Lena and Garnefeld, Ina}}, issn = {{1094-6705}}, journal = {{Journal of Service Research}}, keywords = {{Organizational Behavior and Human Resource Management, Sociology and Political Science, Information Systems}}, number = {{2}}, pages = {{210--228}}, publisher = {{SAGE Publications}}, title = {{{Managing the Bright and Dark Sides of Status Endowment in Hierarchical Loyalty Programs}}}, doi = {{10.1177/1094670514566797}}, volume = {{18}}, year = {{2015}}, } @article{43369, abstract = {{Global competition as well as social and scientific megatrends strongly influence the modern car manufacturing industry. 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{36482, abstract = {{ Die vorliegende quasi-experimentelle Querschnittsuntersuchung verfolgt das Ziel, adaptive Förderleistungen elementarpädagogischer Fachpersonen zu erfassen und Zusammenhänge mit anderen Komponenten elementarpädagogischer Arbeit aufzudecken.
