@article{25605, abstract = {{The nonlinear process of second harmonic generation (SHG) in monolayer (1L) transition metal dichalcogenides (TMD), like WS2, strongly depends on the polarization state of the excitation light. By combination of plasmonic nanostructures with 1L-WS2 by transferring it onto a plasmonic nanoantenna array, a hybrid metasurface is realized impacting the polarization dependency of its SHG. Here, we investigate how plasmonic dipole resonances affect the process of SHG in plasmonic–TMD hybrid metasurfaces by nonlinear spectroscopy. We show that the polarization dependency is affected by the lattice structure of plasmonic nanoantenna arrays as well as by the relative orientation between the 1L-WS2 and the individual plasmonic nanoantennas. In addition, such hybrid metasurfaces show SHG in polarization states, where SHG is usually forbidden for either 1L-WS2 or plasmonic nanoantennas. By comparing the SHG in these channels with the SHG generated by the hybrid metasurface components, we detect an enhancement of the SHG signal by a factor of more than 40. Meanwhile, an attenuation of the SHG signal in usually allowed polarization states is observed. Our study provides valuable insight into hybrid systems where symmetries strongly affect the SHG and enable tailored SHG in 1L-WS2 for future applications.}}, author = {{Spreyer, Florian and Ruppert, Claudia and Georgi, Philip and Zentgraf, Thomas}}, issn = {{1936-0851}}, journal = {{ACS Nano}}, number = {{10}}, pages = {{16719--16728}}, title = {{{Influence of Plasmon Resonances and Symmetry Effects on Second Harmonic Generation in WS2–Plasmonic Hybrid Metasurfaces}}}, doi = {{10.1021/acsnano.1c06693}}, volume = {{15}}, year = {{2021}}, } @article{27970, author = {{Barclay, AW and LSA, Augustin and Brighenti, F and Delport, E and Henry, CJ and Sievenpiper, JL and Usic, K and Yuexin, Y and Zurbau, A and TMS, Wolever and Astrup, A and Bulló, M and Buyken, Anette and Ceriello, A and Ellis, PR and Vanginkel, MA and CWC, Kendall and La Vecchia, C and Livesey, G and Poli, A and Riccardi, G and Salas-Salvadó, J and Trichopoulou, A and Bhaskaran, K and DJA, Jenkins and Willett, WC and Brand-Miller, JC}}, issn = {{2072-6643}}, journal = {{Nutrients}}, number = {{9}}, title = {{{Dietary Glycaemic Index Labelling: A Global Perspective.}}}, doi = {{10.3390/nu13093244}}, volume = {{13}}, year = {{2021}}, } @article{28198, author = {{Steinrück, Hans-Georg}}, issn = {{2158-3226}}, journal = {{AIP Advances}}, number = {{11}}, pages = {{115119}}, title = {{{General relationship between salt concentration and x-ray absorption for binary electrolytes}}}, doi = {{10.1063/5.0072947}}, volume = {{11}}, year = {{2021}}, } @article{26011, author = {{Hense, Dominik and Büngeler, Anne and Kollmann, Fabian and Hanke, Marcel and Orive, Alejandro and Keller, Adrian and Grundmeier, Guido and Huber, Klaus and Strube, Oliver I.}}, issn = {{1525-7797}}, journal = {{Biomacromolecules}}, pages = {{4084–4094}}, title = {{{Self-Assembled Fibrinogen Hydro- and Aerogels with Fibrin-like 3D Structures}}}, doi = {{10.1021/acs.biomac.1c00489}}, volume = {{22}}, year = {{2021}}, } @article{26012, abstract = {{Abstract Purpose Exhaustive cardiovascular load can affect neural processing and is associated with decreases in sensorimotor performance. The purpose of this study was to explore intensity-dependent modulations in brain network efficiency in response to treadmill running assessed from resting-state electroencephalography (EEG) measures. Methods Sixteen trained participants were tested for individual peak oxygen uptake (VO2 peak) and performed an incremental treadmill exercise at 50% (10 min), 70% (10 min) and 90% speed VO2 peak (all-out) followed by cool-down running and active recovery. Before the experiment and after each stage, borg scale (BS), blood lactate concentration (BLa), resting heartrate (HRrest) and 64-channel EEG resting state were assessed. To analyze network efficiency, graph theory was applied to derive small world index (SWI) from EEG data in theta, alpha-1 and alpha-2 frequency bands. Results Analysis of variance for repeated measures revealed significant main effects for intensity on BS, BLa, HRrest and SWI. While BS, BLa and HRrest indicated maxima after all-out, SWI showed a reduction in the theta network after all-out. Conclusion Our explorative approach suggests intensity-dependent modulations of resting-state brain networks, since exhaustive exercise temporarily reduces brain network efficiency. Resting-state network assessment may prospectively play a role in training monitoring by displaying the readiness and efficiency of the central nervous system in different training situations. }}, author = {{Büchel, Daniel and Sandbakk, Øyvind and Baumeister, Jochen}}, issn = {{1439-6319}}, journal = {{European Journal of Applied Physiology}}, pages = {{2423--2435}}, title = {{{Exploring intensity-dependent modulations in EEG resting-state network efficiency induced by exercise}}}, doi = {{10.1007/s00421-021-04712-6}}, year = {{2021}}, } @article{26013, abstract = {{Abstract Mobile Electroencephalography (EEG) provides insights into cortical contributions to postural control.

Our previous CogniDo GI study found no changes of cognition in the early postprandial phase after consumption of two rice types with medium vs. high dietary GI for lunch (i.e., 45 min after starting lunch). This study investigated whether the dietary GI of lunch has an impact on cognition of schoolchildren in the late postprandial phase, 90 min after lunch. Methods A randomized, 2 × 2 crossover intervention study was conducted at a comprehensive school with 5th and 6th grade students. Participants (n = 212) were randomly assigned to either sequence 1 or 2. In the first period, participants of sequence 1 received a dish with high GI rice (GI: 79), those of sequence 2 with medium GI rice (GI: 64)—in the second period, 1 week later, vice versa. Computer-based cognitive testing was performed 90 min after lunch examining tonic alertness, visual search and task switching, and working memory. Treatment effects and treatment effects adjusted for estimated lunch glycemic load (GL) were analyzed using a linear mixed model. Results The selected cognitive parameters were not affected by the GI of lunch 90 min after lunch, neither after intention-to-treat nor in the per-protocol analysis.
