--- _id: '44116' abstract: - lang: eng text: Faradaic reactions including charge transfer are often accompanied with diffusion limitation inside the bulk. Conductive two-dimensional frameworks (2D MOFs) with a fast ion transport can combine both - charge transfer and fast diffusion inside their porous structure. To study remaining diffusion limitations caused by particle morphology, different synthesis routes of Cu-2,3,6,7,10,11-hexahydroxytriphenylene (Cu3(HHTP)2), a copper-based 2D MOF, are used to obtain flake- and rod-like MOF particles. Both morphologies are systematically characterized and evaluated for redox-active Li+ ion storage. The redox mechanism is investigated by means of X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry and impedance spectroscopy. A significant influence of particle morphology for 2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed. This study opens the path for optimization of redox active porous structures to overcome diffusion limitations of Faradaic processes. author: - first_name: Jens Matthies full_name: Wrogemann, Jens Matthies last_name: Wrogemann - first_name: Marco Joes full_name: Lüther, Marco Joes last_name: Lüther - first_name: Peer full_name: Bärmann, Peer last_name: Bärmann - first_name: Mailis full_name: Lounasvuori, Mailis last_name: Lounasvuori - first_name: Ali full_name: Javed, Ali last_name: Javed - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Ronny full_name: Golnak, Ronny last_name: Golnak - first_name: Jie full_name: Xiao, Jie last_name: Xiao - first_name: Tristan full_name: Petit, Tristan last_name: Petit - first_name: Tobias full_name: Placke, Tobias last_name: Placke - first_name: Martin full_name: Winter, Martin last_name: Winter citation: ama: 'Wrogemann JM, Lüther MJ, Bärmann P, et al.

The adsorption process was studied on an electropolished alloy under cathodic and anodic overpotentials, compared to the open circuit potential (OCP). To analyze the adsorption process, various complementary interface analytical techniques were employed, including PM-IRRAS (polarization-modulation infrared reflection-absorption spectroscopy), AFM (atomic force microscopy), XPS (X-ray photoelectron spectroscopy), and E-QCM (electrochemical quartz crystal microbalance) measurements. The polarization experiments were conducted within a potential range where charging of the electric double layer dominates, and Faradaic currents can be disregarded. The findings highlight the significant influence of the interfacial charge distribution on the adsorption of BSA and LYZ onto the alloy surface. Furthermore, electrochemical analysis of the protein layers formed under applied overpotentials demonstrated improved corrosion protection properties. These studies provide valuable insights into protein adsorption on titanium alloys under physiological conditions, characterized by varying potentials of the passive alloy. author: - first_name: Belma full_name: Duderija, Belma id: '54863' last_name: Duderija - first_name: Alejandro full_name: González-Orive, Alejandro last_name: González-Orive - first_name: Christoph full_name: Ebbert, Christoph id: '7266' last_name: Ebbert - first_name: Vanessa full_name: Neßlinger, Vanessa last_name: Neßlinger - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier citation: ama: Duderija B, González-Orive A, Ebbert C, Neßlinger V, Keller A, Grundmeier G.

PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation. article_number: '3915' author: - first_name: Hammad full_name: Ahmed, Hammad last_name: Ahmed - first_name: Muhammad Afnan full_name: Ansari, Muhammad Afnan last_name: Ansari - first_name: Yan full_name: Li, Yan last_name: Li - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Muhammad Qasim full_name: Mehmood, Muhammad Qasim last_name: Mehmood - first_name: Xianzhong full_name: Chen, Xianzhong last_name: Chen citation: ama: Ahmed H, Ansari MA, Li Y, Zentgraf T, Mehmood MQ, Chen X.

For both surfaces, stronger protein adsorption is observed at pH 6 compared to pH 7 and pH 8. PM-IRRAS furthermore provides some qualitative insights into the pH-dependent alterations in the composition of the adsorbed multiprotein films. Changes in the amide II/amide I band area ratio and in particular side-chain IR absorption suggest that the increased adsorption at pH 6 is accompanied by a change in protein film composition. Presumably, this is mostly driven by the adsorption of human serum albumin, which at pH 6 adsorbs more readily and thereby replaces other proteins with lower surface affinities in the resulting multiprotein film. article_number: '6060' author: - first_name: Jingyuan full_name: Huang, Jingyuan last_name: Huang - first_name: Yunshu full_name: Qiu, Yunshu last_name: Qiu - first_name: Felix full_name: Lücke, Felix last_name: Lücke - first_name: Jiangling full_name: Su, Jiangling last_name: Su - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Huang J, Qiu Y, Lücke F, Su J, Grundmeier G, Keller A.

Herein, ferritin adsorption at flat and nanofaceted, single-crystalline Al2O3 surfaces is investigated using atomic force microscopy and X-ray photoelectron spectroscopy. The nanofaceted surfaces are generated by the thermal annealing of Al2O3 wafers at temperatures above 1000 °C, which leads to the formation of faceted saw-tooth-like surface topographies with periodicities of about 160 nm and amplitudes of about 15 nm. Ferritin adsorption at these nanofaceted surfaces is notably suppressed compared to the flat surface at a concentration of 10 mg/mL, which is attributed to lower adsorption affinities of the newly formed facets. Consequently, adsorption is restricted mostly to the pattern grooves, where the proteins can maximize their contact area with the surface. However, this effect depends on the protein concentration, with an inverse trend being observed at 30 mg/mL. Furthermore, different ferritin adsorption behavior is observed at topographically similar nanofacet patterns fabricated at different annealing temperatures and attributed to different step and kink densities. These results demonstrate that while protein adsorption at solid surfaces can be notably affected by nanofacet patterns, fine-tuning protein adsorption in this way requires the precise control of facet properties. article_number: '12808' author: - first_name: Bhanu K. full_name: Pothineni, Bhanu K. last_name: Pothineni - first_name: Sabrina full_name: Kollmann, Sabrina last_name: Kollmann - first_name: Xinyang full_name: Li, Xinyang last_name: Li - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Denise J. full_name: Erb, Denise J. last_name: Erb - first_name: Adrian full_name: Keller, Adrian id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Pothineni BK, Kollmann S, Li X, Grundmeier G, Erb DJ, Keller A.

The surface treatment of the specimens resulted in increased single-lap shear (SLS) strengths before and after hydrothermal aging in 80°C hot water compared to nonpretreated reference specimens. In order to reveal the correlations of laser parameters, resulting surface morphologies and the SLS strength, differently laser pretreated surfaces were characterized at the micro- and nanoscale using optical and scanning electron microscopies. The surface enlargement was quantified with a digital image analysis of cross-sections prepared from the joint interfaces. An analysis of variances (ANOVA) of the SLS results indicated that the laser parameters power and pulse frequency were most critical for obtaining high SLS strengths. Pretreated joint surfaces with a high micro- and nano-surface enlargement and deep solidification structures provide high SLS strengths of up to 50 MPa and almost negligible aging losses of merely 4%. Undercut structures on the pretreated surfaces were found to be beneficial for the mechanical and aging properties when only limited micro- and nanostructuring was applied. article_type: original author: - first_name: Jonathan full_name: Freund, Jonathan last_name: Freund - first_name: Miriam full_name: Löbbecke, Miriam last_name: Löbbecke - first_name: Alexander full_name: Delp, Alexander last_name: Delp - first_name: Frank full_name: Walther, Frank last_name: Walther - first_name: Shuang full_name: Wu, Shuang id: '48039' last_name: Wu orcid: 0000-0001-8645-9952 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster - first_name: Jan full_name: Haubrich, Jan last_name: Haubrich citation: ama: Freund J, Löbbecke M, Delp A, et al.

The hybrid specimen comprises an aluminium sheet of alloy EN AW 6082 in T6 condition and a thermoset Carbon Fibre Reinforced Plastics prepreg. The prepreg pressing process allows the curing reaction of epoxy resin and the joining process to occur simultaneously to avoid an additional bonding process step. The surface of the aluminium sheet was pretreated in advance using a pulsed Nd:YAG laser to enhance the bonding properties. In the first step, the shear edge tests investigated the adhesion properties achieved with different consolidation (temperature, time and pressure) and laser parameters. Then, 3-point bending tests were carried out to investigate the influence of the consolidation parameters on the mechanical properties of the Carbon Fibre Reinforced Plastics-laminate. In this way, the optimal parameter sets for manufacturing hybrid structures were determined. article_type: original author: - first_name: Shuang full_name: Wu, Shuang id: '48039' last_name: Wu orcid: 0000-0001-8645-9952 - first_name: Alexander full_name: Delp, Alexander last_name: Delp - first_name: Jonathan full_name: Freund, Jonathan last_name: Freund - first_name: Frank full_name: Walther, Frank last_name: Walther - first_name: Jan full_name: Haubrich, Jan last_name: Haubrich - first_name: Miriam full_name: Löbbecke, Miriam last_name: Löbbecke - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Wu S, Delp A, Freund J, et al.

The Laser-Powder-Bed-Fusion (L-PBF) and Laser-Metal-Deposition (LMD) processes are considered, as they differ fundamentally in the way a part is manufactured. (2) Known process parameters for low-porosity parts were used to fabricate tensile strength specimens. Half of the specimens were heat-treated, and all specimens were tested for mechanical properties in a quasi-static tensile test. In addition, the material hardness was determined. (3) It was found that, firstly, heat treatment resulted in a sharp increase in mechanical properties such as hardness, elastic modulus, yield strength and ultimate strength. In addition to the increase in these properties, the elongation at break also decreases significantly after heat treatment. The choice of process, on the other hand, does not give either process a clear advantage in terms of mechanical properties but shows that it is necessary to consider the essential mechanical properties for a desired application. article_number: '157' article_type: original author: - first_name: Stefan full_name: Gnaase, Stefan id: '25730' last_name: Gnaase - first_name: Dennis full_name: Niggemeyer, Dennis id: '77214' last_name: Niggemeyer - first_name: Dennis full_name: Lehnert, Dennis id: '90491' last_name: Lehnert - first_name: Christian full_name: Bödger, Christian id: '93904' last_name: Bödger - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Gnaase S, Niggemeyer D, Lehnert D, Bödger C, Tröster T.

Heart rate variability (HRV) offers easily obtainable diagnostic approaches to SRC-associated dysautonomia, but studies investigating HRV during sleep, a crucial time for post-traumatic cerebral regeneration, are relatively sparse. The aim of this study was to assess nocturnal HRV in athletes during their return to sports (RTS) after SRC in their home environment using wireless wrist sensors (E4, Empatica, Milan, Italy) and to explore possible relations with clinical concussion-associated sleep symptoms. Eighteen SRC athletes wore a wrist sensor obtaining photoplethysmographic data at night during RTS as well as one night after full clinical recovery post RTS (>3 weeks). Nocturnal heart rate and parasympathetic activity of HRV (RMSSD) were calculated and compared using the Mann–Whitney U Test to values of eighteen; matched by sex, age, sport, and expertise, control athletes underwent the identical protocol. During RTS, nocturnal RMSSD of SRC athletes (Mdn = 77.74 ms) showed a trend compared to controls (Mdn = 95.68 ms, p = 0.021, r = −0.382, p adjusted using false discovery rate = 0.126) and positively correlated to “drowsiness” (r = 0.523, p = 0.023, p adjusted = 0.046). Post RTS, no differences in RMSSD between groups were detected. The presented findings in nocturnal cardiac parasympathetic activity during nights of RTS in SRC athletes might be a result of concussion, although its relation to recovery still needs to be elucidated. Utilization of wireless sensors and wearable technologies in home-based settings offer a possibility to obtain helpful objective data in the management of SRC. article_number: '4190' author: - first_name: Anne Carina full_name: Delling, Anne Carina last_name: Delling - first_name: Rasmus full_name: Jakobsmeyer, Rasmus id: '9583' last_name: Jakobsmeyer orcid: 0000-0002-9385-0834 - first_name: Jessica full_name: Coenen, Jessica last_name: Coenen - first_name: Nele full_name: Christiansen, Nele last_name: Christiansen - first_name: Claus full_name: Reinsberger, Claus id: '48978' last_name: Reinsberger citation: ama: Delling AC, Jakobsmeyer R, Coenen J, Christiansen N, Reinsberger C.

Students often demonstrate limited ability to link these different levels. Augmented reality (AR) offers the possibility to increase contiguity by embedding virtual models into hands-on experiments. Therefore, this paper presents a pre- and post-test study investigating how learning and cognitive load are influenced by AR during hands-on experiments. Three comparison groups (AR, animation and filmstrip), with a total of N = 104 German secondary school students, conducted and explained two hands-on experiments. Whereas the AR group was allowed to use an AR app showing virtual models of the processes on the submicroscopic level during the experiments, the two other groups were provided with the same dynamic or static models after experimenting. Results indicate no significant learning gain for the AR group in contrast to the two other groups. The perceived intrinsic cognitive load was higher for the AR group in both experiments as well as the extraneous load in the second experiment. It can be concluded that AR could not unleash its theoretically derived potential in the present study. article_number: '9' author: - first_name: Hendrik full_name: Peeters, Hendrik id: '49942' last_name: Peeters orcid: https://orcid.org/ 0000-0002-7143-3781 - first_name: Sebastian full_name: Habig, Sebastian last_name: Habig - first_name: Sabine full_name: Fechner, Sabine id: '54823' last_name: Fechner orcid: 0000-0001-5645-5870 citation: ama: Peeters H, Habig S, Fechner S.

Here, we investigate the salting-out of different DNA origami shapes by the kosmotropic salt ammonium sulfate that is routinely employed in protein precipitation. We find that centrifugation in the presence of 3 M ammonium sulfate results in notable precipitation of DNA origami nanostructures but not of double-stranded genomic DNA. The precipitated DNA origami nanostructures can be resuspended in ammonium sulfate-free buffer without apparent formation of aggregates or loss of structural integrity. Even though quasi-1D six-helix bundle DNA origami are slightly less susceptible toward salting-out than more compact DNA origami triangles and 24-helix bundles, precipitation and recovery yields appear to be mostly independent of DNA origami shape and superstructure. Exploiting the specificity of ammonium sulfate salting-out for DNA origami nanostructures, we further apply this method to separate DNA origami triangles from genomic DNA fragments in a complex mixture. Our results thus demonstrate the possibility of concentrating and purifying DNA origami nanostructures by ammonium sulfate-induced salting-out. author: - first_name: Marcel full_name: Hanke, Marcel last_name: Hanke - first_name: Niklas full_name: Hansen, Niklas last_name: Hansen - first_name: Ruiping full_name: Chen, Ruiping last_name: Chen - first_name: Guido full_name: Grundmeier, Guido last_name: Grundmeier - first_name: Karim full_name: Fahmy, Karim last_name: Fahmy - first_name: Adrian full_name: Keller, Adrian last_name: Keller citation: ama: Hanke M, Hansen N, Chen R, Grundmeier G, Fahmy K, Keller A.

Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles. article_number: '1387' author: - first_name: B. full_name: Jonas, B. last_name: Jonas - first_name: D. full_name: Heinze, D. last_name: Heinze - first_name: E. full_name: Schöll, E. last_name: Schöll - first_name: P. full_name: Kallert, P. last_name: Kallert - first_name: T. full_name: Langer, T. last_name: Langer - first_name: S. full_name: Krehs, S. last_name: Krehs - first_name: A. full_name: Widhalm, A. last_name: Widhalm - first_name: K.

Material properties of electrodes and electrolytes along with cell parameters such as stack pressure and temperature have coupled, synergistic, and sometimes deleterious effects on fast-charging performance. We develop a new experimental testbed that allows precise and conformal application of electrode stack pressure. We focus on cell capacity degradation using single-layer pouch cells with graphite anodes, LiNi0.5Mn0.3Co0.2O2 (NMC532) cathodes, and carbonate-based electrolyte. In the tested range (10 – 125 psi), cells cycled at higher pressure show higher capacity and less capacity fading. Additionally, Li plating decreases with increasing pressure as observed with scanning electron microscopy (SEM) and optical imaging. While the loss of Li inventory from Li plating is the largest contributor to capacity fade, electrochemical and SEM examination of the NMC cathodes after XFC experiments show increased secondary particle damage at lower pressure. We infer that the better performance at higher pressure is due to more homogenous reactions of active materials across the electrode and less polarization through the electrode thickness. Our study emphasizes the importance of electrode stack pressure in XFC batteries and highlights its subtle role in cell conditions." author: - first_name: Chuntian full_name: Cao, Chuntian last_name: Cao - first_name: Hans-Georg full_name: Steinrück, Hans-Georg id: '84268' last_name: Steinrück orcid: 0000-0001-6373-0877 - first_name: Partha P full_name: Paul, Partha P last_name: Paul - first_name: Alison R. full_name: Dunlop, Alison R. last_name: Dunlop - first_name: Stephen E. full_name: Trask, Stephen E. last_name: Trask - first_name: Andrew full_name: Jansen, Andrew last_name: Jansen - first_name: Robert M full_name: Kasse, Robert M last_name: Kasse - first_name: Vivek full_name: Thampy, Vivek last_name: Thampy - first_name: Maha full_name: Yusuf, Maha last_name: Yusuf - first_name: Johanna full_name: Nelson Weker, Johanna last_name: Nelson Weker - first_name: Badri full_name: Shyam, Badri last_name: Shyam - first_name: Ram full_name: Subbaraman, Ram last_name: Subbaraman - first_name: Kelly full_name: Davis, Kelly last_name: Davis - first_name: Christina M full_name: Johnston, Christina M last_name: Johnston - first_name: Christopher J full_name: Takacs, Christopher J last_name: Takacs - first_name: Michael full_name: Toney, Michael last_name: Toney citation: ama: Cao C, Steinrück H-G, Paul PP, et al.

In combination with additive manufacturing, which facilitates great flexibility of the implant design, it is possible to selectively adjust the microstructure of the material in the process, thereby control the corrosion and fatigue behavior. In the present study, conventional hot-rolled (HR) pure iron is compared to pure iron manufactured by electron beam melting (EBM). The microstructure, the corrosion behavior and the fatigue properties were studied comprehensively. The investigated sample conditions showed significant differences in the microstructures that led to changes in corrosion and fatigue properties. The EBM iron showed significantly lower fatigue strength compared to the HR iron. These different fatigue responses were observed under purely mechanical loading as well as with superimposed corrosion influence and are summarized in a model that describes the underlying failure mechanisms. article_number: '18' author: - first_name: Steffen full_name: Wackenrohr, Steffen last_name: Wackenrohr - first_name: Christof Johannes Jaime full_name: Torrent, Christof Johannes Jaime last_name: Torrent - first_name: Sebastian full_name: Herbst, Sebastian last_name: Herbst - first_name: Florian full_name: Nürnberger, Florian last_name: Nürnberger - first_name: Philipp full_name: Krooss, Philipp last_name: Krooss - first_name: Christoph full_name: Ebbert, Christoph last_name: Ebbert - first_name: Markus full_name: Voigt, Markus id: '15182' last_name: Voigt - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Thomas full_name: Niendorf, Thomas last_name: Niendorf - first_name: Hans Jürgen full_name: Maier, Hans Jürgen last_name: Maier citation: ama: Wackenrohr S, Torrent CJJ, Herbst S, et al.
