@inproceedings{23756, abstract = {{Creativity is perceived to be one of the core competences to succeed in the modern world. It is connected to art, music, dancing, etc., but there is just little insight into the role of creativity in science. As data analysis plays a major role in science, creative thinking has to be used to form theories out of observations. This study uses models-of-data to represent the mental model of the students. Within models-of-data different observations and previous knowledge are linked through different types of links, e.g. causal links. The goal of this study was to examine the creative aspect of data evaluation in presence of anomalous data. The students were confronted with two experiments which contradicted each other with regard to the underlying theory. Afterwards the students were asked to decide about their favored theory and reasoning about their choice in their lab reports. The model-of-data, which was reconstructed from the lab reports of the students, was used to extract creative aspects in the mental modelling process. Furthermore, a pre-post-questionnaire on epistemological beliefs of the students was conducted. Students mostly acquired an unscientific view on epistemology in school. The question was whether the confrontation with anomalous data and the triggering of creative modelling processes have any influence on this. The results show that most students did not take anomalous data into account in their modelling processes. They did either not recognise or just ignore the data. Just a few students worked on their theory because of the new, contradictory data. The students working on their theory scored higher in the post-questionnaire, so a positive effect of creativity on scientific epistemology can be assumed. Thus, creativity obviously gets a part of science and should be taught in school science in order to make students aware of their own creative potential.}}, author = {{Pollmeier, Pascal and Fechner, Sabine}}, booktitle = {{The beauty and pleasure of understanding: engaging with contemporary challenges through science education.

Here, we investigate the adsorption of DNA origami nanostructures in nanohole arrays which represent an important class of biosensors and may benefit from the incorporation of DNA origami-based molecular probes. Nanoholes with well-defined diameter that enable the adsorption of single DNA origami triangles are fabricated in Au films on Siwafers by nanosphere lithography. The efficiency of directed DNA origami adsorption on the exposed SiO2 areas at the bottoms of the nanoholes is evaluated in dependence of various parameters, i.e., Mg2+ and DNA origami concentrations, buffer strength, adsorption time, and nanohole diameter. We observe that the buffer strength has a surprisingly strong effect on DNA origami adsorption in the nanoholes and that multiple DNA origami triangles with 120 nm edge length can adsorb in nanoholes as small as 120 nm in diameter. We attribute the latter observation to the low lateral mobility of once adsorbed DNA origami on the SiO2 surface, in combination with parasitic adsorption to the Au film. While parasitic adsorption can be suppressed by modifying the Au film with a hydrophobic self-assembled monolayer, the limited surface mobility of the adsorbed DNA origami still leads to poor localization accuracy in the nanoholes and results in many DNA origami crossing the boundary to the Au film even under optimized conditions. We discuss possible ways to minimize this effect by varying the composition of the adsorption buffer, employing different fabrication conditions, or using other substrate materials for nanohole array fabrication.}}, author = {{Brassat, Katharina and Ramakrishnan, Saminathan and Bürger, Julius and Hanke, Marcel and Doostdar, Mahnaz and Lindner, Jörg and Grundmeier, Guido and Keller, Adrian}}, issn = {{0743-7463}}, journal = {{Langmuir}}, publisher = {{American Chemical Society (ACS)}}, title = {{{On the Adsorption of DNA Origami Nanostructures in Nanohole Arrays}}}, doi = {{10.1021/acs.langmuir.8b00793}}, year = {{2018}}, } @article{23623, author = {{Chen, Lin and Chen, Kan-Sheng and Chen, Xinjie and Ramirez, Giovanni and Huang, Zhennan and Geise, Natalie R. and Steinrück, Hans-Georg and Fisher, Brandon L. and Shahbazian-Yassar, Reza and Toney, Michael F. and Hersam, Mark C. and Elam, Jeffrey W.}}, issn = {{1944-8244}}, journal = {{ACS Applied Materials & Interfaces}}, pages = {{26972--26981}}, title = {{{Novel ALD Chemistry Enabled Low-Temperature Synthesis of Lithium Fluoride Coatings for Durable Lithium Anodes}}}, doi = {{10.1021/acsami.8b04573}}, volume = {{20}}, year = {{2018}}, } @article{23624, author = {{Horowitz, Yonatan and Steinrück, Hans-Georg and Han, Hui-Ling and Cao, Chuntian and Abate, Iwnetim Iwnetu and Tsao, Yuchi and Toney, Michael F. and Somorjai, Gabor A.}}, issn = {{1530-6984}}, journal = {{Nano Letters}}, pages = {{2105--2111}}, title = {{{Fluoroethylene Carbonate Induces Ordered Electrolyte Interface on Silicon and Sapphire Surfaces as Revealed by Sum Frequency Generation Vibrational Spectroscopy and X-ray Reflectivity}}}, doi = {{10.1021/acs.nanolett.8b00298}}, volume = {{18}}, year = {{2018}}, } @article{23625, abstract = {{

However, the evolution of their interface structure with the cation’s alkyl chain length n from Coulomb to van der Waals interaction domination has not yet been studied for even a single broad homologous RTIL series. We present here such a study of the liquid–air interface for n=2to 22, using angstrom-resolution X-ray methods. For n<6, a typical “simple liquid” monotonic surface-normal electron density profile ρe(z) is obtained, like those of water and organic solvents. For n>6, increasingly more pronounced nanoscale self-segregation of the molecules’ charged moieties and apolar chains yields surface layering with alternating regions of headgroups and chains. The layering decays into the bulk over a few, to a few tens, of nanometers. The layering periods and decay lengths, their linear n dependence, and slopes are discussed within two models, one with partial-chain interdigitation and the other with liquid-like chains. No surface-parallel long-range order is found within the surface layer. For n=22, a different surface phase is observed above melting. Our results also impact general liquid-phase issues like supramolecular self-aggregation and bulk–surface structure relations.}}, author = {{Haddad, Julia and Pontoni, Diego and Murphy, Bridget M. and Festersen, Sven and Runge, Benjamin and Magnussen, Olaf M. and Steinrück, Hans-Georg and Reichert, Harald and Ocko, Benjamin M. and Deutsch, Moshe}}, issn = {{0027-8424}}, journal = {{Proceedings of the National Academy of Sciences}}, pages = {{E1100--E1107}}, title = {{{Surface structure evolution in a homologous series of ionic liquids}}}, doi = {{10.1073/pnas.1716418115}}, volume = {{115}}, year = {{2018}}, } @inbook{23751, author = {{Nitz, Sandra and Fechner, Sabine}}, booktitle = {{Theorien in der naturwissenschaftsdidaktischen Forschung}}, editor = {{Krüger, Dirk and Parchmann, Ilka and Schecker, Horst}}, publisher = {{Springer}}, title = {{{Mentale Modelle}}}, doi = {{10.1007/978-3-662-56320-5_5}}, year = {{2018}}, } @inproceedings{23775, author = {{Akman, Perihan and Fechner, Sabine}}, booktitle = {{Electronic Proceedings of the ESERA 2017 Conference.
