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. article_number: '5109' author: - first_name: Belma full_name: Duderija, Belma last_name: Duderija - first_name: Alejandro full_name: González-Orive, Alejandro last_name: González-Orive - first_name: Christoph full_name: Ebbert, Christoph last_name: Ebbert - first_name: Vanessa full_name: Neßlinger, Vanessa last_name: Neßlinger - first_name: Adrian full_name: Keller, Adrian last_name: Keller - first_name: Guido full_name: Grundmeier, Guido last_name: Grundmeier citation: ama: Duderija B, González-Orive A, Ebbert C, Neßlinger V, Keller A, Grundmeier G.

Twenty-four female footballers (14.9 ± 0.9 year) performed unanticipated cutting maneuvers in a laboratory setting and on the football pitch during football-specific exercises (F-EX) and games (F-GAME). Knee joint moments were collected in the laboratory and grouped using hierarchical agglomerative clustering. The clusters were used to investigate the kinematics collected on field through wearable sensors. Three clusters emerged: Cluster 1 presented the lowest knee moments; Cluster 2 presented high knee extension but low knee abduction and rotation moments; Cluster 3 presented the highest knee abduction, extension, and external rotation moments. In F-EX, greater knee abduction angles were found in Cluster 2 and 3 compared to Cluster 1 (p = 0.007). Cluster 2 showed the lowest knee and hip flexion angles (p < 0.013). Cluster 3 showed the greatest hip external rotation angles (p = 0.006). In F-GAME, Cluster 3 presented the greatest knee external rotation and lowest knee flexion angles (p = 0.003). Clinically relevant differences towards ACL injury identified in the laboratory reflected at-risk patterns only in part when cutting on the field: in the field, low-risk players exhibited similar kinematic patterns as the high-risk players.

In this work, multiprotein adsorption from diluted human serum at gold and oxidized iron surfaces is investigated at different serum concentrations and pH values. Adsorption-induced changes in surface topography and the total amount of adsorbed proteins are quantified by atomic force microscopy (AFM) and polarization-modulation infrared reflection absorption spectroscopy (PM-IRRAS), respectively. 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.

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.

While the formal oxidation state is easily evaluated, the real physical oxidation state value is often difficult to determine and significantly varies from the formal values. Determination of the ionization threshold in X-ray absorption spectroscopy (XANES) relies on the absorption edge position and sometimes poses limitations, mainly due to the edge resonances. Moreover, the lower energy states can be probed only within x-soft or XUV photons providing only surface state information of probed materials. Here, we employ high energy resolution off-resonant spectroscopy to determine both 1s and 3p binding energies of Fe-based materials and therefore correlate to their physical oxidation state. The results are compared to the ones obtained with classical X-ray absorption, X-ray emission, and photoelectron spectroscopies. The observed differences in binding energies are discussed in a frame of initial and final state interactions with the atom's electronic configurations. The presented methodology is discussed towards potential use to single-shot experiments and application at X-ray free-electron lasers. Alternatively, core level X-ray emission spectroscopy can be used, but the emission line positions are strongly affected by spin-orbit interaction. However, due to the energy transfer from the photon to the excited core electron, the same information as in XANES is probed in high energy resolution off-resonant spectroscopy (HEROS). Based on the Kramers–Heisenberg theory, we propose a new approach for ionization threshold determination which is free of the limitations encountered in XANES-based determination of the core state energy. Namely, the value of core state energy can be determined analytically using a few HEROS spectra recorded with significantly higher spectral resolution. This approach provides a basis for the universal physical oxidation state determination method. author: - first_name: Michał full_name: Nowakowski, Michał id: '78878' last_name: Nowakowski orcid: 0000-0002-3734-7011 - first_name: Aleksandr full_name: Kalinko, Aleksandr last_name: Kalinko - first_name: Jakub full_name: Szlachetko, Jakub last_name: Szlachetko - first_name: Rafał full_name: Fanselow, Rafał last_name: Fanselow - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 citation: ama: Nowakowski M, Kalinko A, Szlachetko J, Fanselow R, Bauer M.

Although these materials have been widely studied for a variety of applications, the mechanisms underlying the pyrolysis are yet poorly understood. This study provides a comprehensive temperature-resolved characterization of the chemical composition, morphology and crystallinity of sucrose-derived hydrochar during pyrolysis. Thermogravimetric analysis, differential scanning calorimetry, and elemental analysis have shown that the dry hydrochar loses about 41% of its dry mass due to the exothermic disintegration of oxygen-containing groups until the carbonization is completed at about 850 °C with a total carbon yield of 93%. The carbonization and aromatization of the initially furanic and keto-aliphatic structure were analyzed by 13C solid-state nuclear magnetic resonance spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The transition from an amorphous to a nanocrystalline graphitic structure was analyzed using X-ray diffraction and Raman spectroscopy. The pore formation mechanism was examined by helium ion microscopy, transmission electron microscopy, and nitrogen adsorption measurements. The results indicate the formation of oxygen-rich nanoclusters up to 700 °C, which decompose up to 750 °C leaving behind equally sized pores, resulting in a surface area of up to 480 m2/g. article_number: '105404' article_type: original author: - first_name: Martin full_name: Wortmann, Martin last_name: Wortmann - first_name: Waldemar full_name: Keil, Waldemar last_name: Keil - first_name: Bennet full_name: Brockhagen, Bennet last_name: Brockhagen - first_name: Jan full_name: Biedinger, Jan last_name: Biedinger - first_name: Michael full_name: Westphal, Michael last_name: Westphal - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Elise full_name: Diestelhorst, Elise last_name: Diestelhorst - first_name: Wiebke full_name: Hachmann, Wiebke last_name: Hachmann - first_name: Yanjing full_name: Zhao, Yanjing last_name: Zhao - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Günter full_name: Reiss, Günter last_name: Reiss - first_name: Bruno full_name: Hüsgen, Bruno last_name: Hüsgen - first_name: Claudia full_name: Schmidt, Claudia id: '466' last_name: Schmidt orcid: 0000-0003-3179-9997 - first_name: Klaus full_name: Sattler, Klaus last_name: Sattler - first_name: Natalie full_name: Frese, Natalie last_name: Frese citation: ama: Wortmann M, Keil W, Brockhagen B, et al.

An increasing bidirectional energy flow stresses the assets of the distribution grid, especially medium voltage switchgear. This calls for improved maintenance strategies to prevent critical failures. Predictive maintenance, a maintenance strategy relying on current condition data of assets, serves as a guideline. Novel sensors covering thermal, mechanical, and partial discharge aspects of switchgear, enable continuous condition monitoring of some of the most critical assets of the distribution grid. Combined with machine learning algorithms, the demands put on the distribution grid by the energy and mobility revolutions can be handled. In this paper, we review the current state-of-the-art of all aspects of condition monitoring for medium voltage switchgear. Furthermore, we present an approach to develop a predictive maintenance system based on novel sensors and machine learning. We show how the existing medium voltage grid infrastructure can adapt these new needs on an economic scale. article_number: '2099' author: - first_name: Martin W. full_name: Hoffmann, Martin W. last_name: Hoffmann - first_name: Stephan full_name: Wildermuth, Stephan last_name: Wildermuth - first_name: Ralf full_name: Gitzel, Ralf last_name: Gitzel - first_name: Aydin full_name: Boyaci, Aydin last_name: Boyaci - first_name: Jörg full_name: Gebhardt, Jörg last_name: Gebhardt - first_name: Holger full_name: Kaul, Holger last_name: Kaul - first_name: Ido full_name: Amihai, Ido last_name: Amihai - first_name: Bodo full_name: Forg, Bodo last_name: Forg - first_name: Michael full_name: Suriyah, Michael last_name: Suriyah - first_name: Thomas full_name: Leibfried, Thomas last_name: Leibfried - first_name: Volker full_name: Stich, Volker last_name: Stich - first_name: Jan full_name: Hicking, Jan last_name: Hicking - first_name: Martin full_name: Bremer, Martin last_name: Bremer - first_name: Lars full_name: Kaminski, Lars last_name: Kaminski - first_name: Daniel full_name: Beverungen, Daniel id: '59677' last_name: Beverungen - first_name: Philipp full_name: zur Heiden, Philipp id: '64394' last_name: zur Heiden - first_name: Tanja full_name: Tornede, Tanja last_name: Tornede citation: ama: Hoffmann MW, Wildermuth S, Gitzel R, et al.
