@article{64066, abstract = {{Multi-stimuli responsive materials based on cellulose nanocrystals (CNCs), especially using non-conventional stimuli including light, still need more explorations, to fulfill the requirements of complicated application environments. The structure determination of functional groups on the CNC surface constitutes a significant challenge, partially due to their low amounts. In this study, rhodamine spiroamide groups are immobilized onto the surface of CNCs leading to a hybrid compound being responsive to pH-values, heat and UV light. After the treatment with external stimuli, the fluorescent and correlated optical color change can be induced, which refers to a ring opening and closing process. Amine and amide groups in rhodamine spiroamide play the critical role in this switching process. Solid-state NMR spectroscopy coupled with sensitivity-enhanced dynamic nuclear polarization (DNP) was used to measure 13C and 15N in natural abundance, allowing the determination of structural changes during the switching process. It is shown that a temporary bond through an electrostatic interaction could be formed within the confined environment on the CNC surface during the heat treatment. The carboxyl groups on the CNC surface play a pivotal role in stabilizing the open status of rhodamine spiroamide groups.}}, author = {{Zhao, Li and Li, Wei and Plog, Andreas and Xu, Yeping and Buntkowsky, Gerd and Gutmann, Torsten and Zhang, Kai}}, journal = {{Physical Chemistry Chemical Physics}}, number = {{47}}, pages = {{26322–26329}}, publisher = {{The Royal Society of Chemistry}}, title = {{{Multi-responsive cellulose nanocrystal-rhodamine conjugates: an advanced structure study by solid-state dynamic nuclear polarization (DNP) NMR}}}, doi = {{10.1039/C4CP04096A}}, volume = {{16}}, year = {{2014}}, } @article{64064, author = {{Xu, Yeping and Watermann, Tobias and Limbach, Hans-Heinrich and Gutmann, Torsten and Sebastiani, Daniel and Buntkowsky, Gerd}}, journal = {{Physical Chemistry Chemical Physics}}, number = {{20}}, pages = {{9327–9336}}, title = {{{Water and small organic molecules as probes for geometric confinement in well-ordered mesoporous carbon materials}}}, doi = {{10.1039/c4cp00808a}}, volume = {{16}}, year = {{2014}}, } @article{64061, author = {{Werner, Mayke and Rothermel, Niels and Breitzke, Hergen and Gutmann, Torsten and Buntkowsky, Gerd}}, journal = {{Israel Journal of Chemistry}}, number = {{1-2}}, pages = {{60–73}}, title = {{{Recent Advances in Solid State NMR of Small Molecules in Confinement}}}, doi = {{10.1002/ijch.201300095}}, volume = {{54}}, year = {{2014}}, } @article{64036, author = {{Sauer, Grit and Nasu, Daichi and Tietze, Daniel and Gutmann, Torsten and Englert, Simon and Avrutina, Olga and Kolmar, Harald and Buntkowsky, Gerd}}, journal = {{Angewandte Chemie International Edition}}, number = {{47}}, pages = {{12941–12945}}, title = {{{Effective PHIP Labeling of Bioactive Peptides Boosts the Intensity of the NMR Signal}}}, doi = {{10.1002/anie.201404668}}, volume = {{53}}, year = {{2014}}, } @article{64024, author = {{Pieters, Gregory and Taglang, Celine and Bonnefille, Eric and Gutmann, Torsten and Puente, Celine and Berthet, Jean-Claude and Dugave, Christophe and Chaudret, Bruno and Rousseau, Bernard}}, journal = {{Angewandte Chemie International Edition}}, number = {{1}}, pages = {{230–234}}, title = {{{Regioselective and Stereospecific Deuteration of Bioactive Aza Compounds by the Use of Ruthenium Nanoparticles}}}, doi = {{10.1002/anie.201307930}}, volume = {{53}}, year = {{2014}}, } @article{64003, author = {{Lego, Denise and Plaumann, Markus and Trantzschel, Thomas and Bargon, Joachim and Scheich, Henning and Buntkowsky, Gerd and Gutmann, Torsten and Sauer, Grit and Bernarding, Johannes and Bommerich, Ute}}, journal = {{NMR in Biomedicine}}, number = {{7}}, pages = {{810–816}}, title = {{{Parahydrogen-induced polarization of carboxylic acids: a pilot study of valproic acid and related structures}}}, doi = {{10.1002/nbm.3123}}, volume = {{27}}, year = {{2014}}, } @article{63936, author = {{Buntkowsky, Gerd and Gutmann, Torsten and Petrova, Marina V. and Ivanov, Konstantin L. and Bommerich, Ute and Plaumann, Markus and Bernarding, Johannes}}, journal = {{Solid State Nuclear Magnetic Resonance}}, pages = {{20–29}}, title = {{{Dipolar induced Para-Hydrogen-Induced Polarization}}}, doi = {{10.1016/j.ssnmr.2014.07.002}}, volume = {{63-64}}, year = {{2014}}, } @article{63919, author = {{Abdulhussain, Safaa and Breitzke, Hergen and Ratajczyk, Tomasz and Gruenberg, Anna and Srour, Mohamad and Arnaut, Danjela and Weidler, Heiko and Kunz, Ulrike and Kleebe, Hans Joachim and Bommerich, Ute and Bernarding, Johannes and Gutmann, Torsten and Buntkowsky, Gerd}}, journal = {{Chemistry A European Journal}}, number = {{4}}, pages = {{1159–1166}}, title = {{{Synthesis, Solid-State NMR Characterization, and Application for Hydrogenation Reactions of a Novel Wilkinson’s-Type Immobilized Catalyst}}}, doi = {{10.1002/chem.201303020}}, volume = {{20}}, year = {{2014}}, } @article{63925, author = {{Bonnefille, Eric and Novio, Fernando and Gutmann, Torsten and Poteau, Romuald and Lecante, Pierre and Jumas, Jean-Claude and Philippot, Karine and Chaudret, Bruno}}, issn = {{2040-3364}}, journal = {{Nanoscale}}, number = {{16}}, pages = {{9806–9816}}, title = {{{Tin-decorated ruthenium nanoparticles: a way to tune selectivity in hydrogenation reaction}}}, doi = {{10.1039/c4nr00791c}}, volume = {{6}}, year = {{2014}}, } @article{22186, abstract = {{The reproducibility and reliability of quality aspects are an important challenge of the polymer laser sintering process.

Emergent technologies in particular have a high potential for radical innovations. However, the high innovation potential is offset by high market and technology uncertainties, which are caused by incomplete knowledge of the technology potential and development as well as of potential application contexts. In connection with emergent technologies, the finding of potential - i.e. the generation of knowledge regarding the potentials - is essential, as it lays the foundation for the search for potential application contexts. At the same time, this represents a challenge, since conventional market research approaches only have a limited effect here. The question that arises is how technology potentials can be derived in a discursive way. Furthermore, we hypothesize that the TRIZ approach has great potential for this: (1) In a reversal of the TRIZ logic, we see a way of accessing the TRIZ knowledge base via an analogy; (2) In this way, contradictions within the meaning of TRIZ can be determined, which can be addressed by the technology; (3) A continuous specification of the contradictions represents a possibility to infer technology potentials. The present article presents an approach developed at the Heinz Nixdorf Institute for a TRIZ-based potential finding within the framework of technology-induced innovation processes. The approach comprises the three phases of technology analysis, technology foresight and technology potential analysis. Based on the analysis of the current performance of the technology, the future performance is anticipated using the TRIZ development pattern. By reversing the TRIZ logic, technology potentials are finally determined. }}, author = {{Wall, Marina and Gausemeier, Jürgen and Peter, Stefan}}, editor = {{Gausemeier, Jürgen}}, pages = {{95--123}}, publisher = {{publishing series of the Heinz Nixdorf Institute, Paderborn}}, title = {{{TRIZ-based potential finding in technology-induced innovation processes}}}, year = {{2014}}, } @inproceedings{28186, abstract = {{Product innovations are of great strategic importance for securing the long-term competitiveness of companies.
