    These 285 documents have been used for the three sections that are part of the results of this article (documents statistics, bibliometric analysis, and literature review statistics). For this purpose, it was necessary to carry out an exhaustive review of the 285 selected documents and to complement this information with the data provided by Scopus. The data-charting process was as follows: the four researchers agreed on the types of data to be extracted, two of them carried out the review while the other two supervised. If any type of data worthy of investigation emerged during the reading, it was discussed, and if appropriate, included, making it an iterative process. For each of the documents, the following variables were collected in a table: author/s, title of the document, year of publication, journal in which it was published, type of document (article or review), number of citations and citations per year, relevance (weighting given by Scopus), DOI, geographical location of researchers, abstract, author keywords and keywords suggested by Scopus, JIF, JCI and H-index information of the journal in which the document is published (with quartiles and percentiles), subject area categories provided by Scopus, territory studied, renewable energy source studied, research technique or methodology used, primary data source used and years collected. In addition, for articles using quantitative techniques, all variables included in each model have been collected.

    Synopsis Climate change can directly and indirectly affect species distribution. Warming may allow for invasive species, such as apple snails, to migrate to higher latitudes where temperatures are more conducive to their survival and invasion success. Higher temperatures and lower pH ranges have been previously documented to affect the form and function of calcium carbonate shells, which serve many functions, including protection from predators and thermoregulation. This study aimed to quantify differences in the morphology and mechanical properties of invasive apple snail, Pomacea maculata, shells after altering temperature and pH. We mechanically tested shells among three five-week treatments: control, higher temperature, and lower pH. Ultimate Strength increased in shells that were exposed to higher temperatures, but Young’s Modulus and Peak Load did not differ among control, temperature, and pH treatments. Apple snails in higher temperature tanks increased their shell length over the five-week trials. Although snail morphometrics did not differ between sexes, male shells exhibited a higher Peak Load, Young’s Modulus, and Ultimate Strength compared to female shells. Our findings are consistent with previous gastropod studies, in that a lower pH is associated with a decrease in shell size, and higher temperatures yield larger snail shells with a higher ultimate strength. Peak Load did not significantly differ among treatments, which suggests that the cross-sectional area is relatively important when considering this species mechanical performance today and in future climates. Due to the intense nutritional and calcium demands of egg production, female snails may be more susceptible to weakened shells due to low pH environments caused by climate change.

    The phenomenon of global change is prompting the implementation of measures aimed at mitigating various effects, with humans being primarily impacted. The objective of this investigation is to analyse the potential self-sufficiency in the built environment through the utilisation of energy generated by photovoltaic systems. These systems have the capacity to reduce or even eliminate the reliance on grid electricity and non-renewable energy sources. The study commences with the delineation of eight neighbourhoods within the city of Madrid, Spain, each characterised by a distinct building typology. In order to ascertain the degree of self-sufficiency, this study calculates the energy production from solar photovoltaic systems installed on rooftops, and then proceeds to assess the energy consumption of each building. The results of the analysis demonstrate the capacity of photovoltaic installations to meet the electricity demands of buildings, such as single-family houses, almost completely, and partially in others, such as multi-family dwellings with multiple units per floor. Furthermore, the impact of differences in building height and urban context on self-sufficiency potential is explored.

    This research investigates the flight behavior of refuse-derived fuel (RDF) in a drop shaft using Computer Vision to obtain statistical data on the aerodynamic properties of the particles. Methods to determine 3D geometry models of complex-shaped particles by photogrammetry and to obtain time resolved particle positions and velocities are described. Furthermore, an approach to obtain the frequency distribution of drag and lift coefficients from photogrammetric analysis and drop shaft experiments is presented. The image evaluation is based on algorithms of the open-source libraries OpenCV, COLMAP as well as MeshLab and Open3D. The precision of the system is validated employing model particles with known geometry. The 3D particle models overestimate the particle surface area by 4.58 %, the position detection works with a mean deviation of 2.73 %. The average sink rate is calculated with an accuracy of 4.87 % and the drag coefficient with an accuracy of 2.08 %. Finally, the frequency distribution of four RDF fractions, namely, textiles, cardboard, 3D plastic particles and 2D plastic foils are presented.

    Authors: Fan, Xinyang;

    Der Klimawandel wird sich voraussichtlich auf das Grundwasser auswirken, aber die Prognosen sind sehr unsicher. Die Quantifizierung der historischen Auswirkungen ermöglicht ein besseres Verständnis der Reaktion des Grundwassers, wurde aber aufgrund des komplexen Einflusses verschiedener Faktoren, wie Grundwasserentnahme für die landwirtschaftliche Bewässerung und Landnutzungsänderungen, nur selten untersucht. Diese Arbeit zielt darauf ab, zum Verständnis und zur Quantifizierung der historischen Auswirkungen von Klimawandel und -schwankungen auf das Grundwasser durch drei miteinander verbundene Forschungsfragen beizutragen: Frage 1: Wie sensitiv reagieren der Grundwasserstand und die Grundwasserneubildung auf Klimaschwankungen in Australien? Frage 2: Wie stark sind die Veränderungen des Grundwasserstands auf den anthropogenen Klimawandel in Australien zurückzuführen und wann haben sich diese Auswirkungen auf das Grundwasser bemerkbar gemacht? Frage 3: Wie haben und werden sich die langfristigen Klimawandel und -schwankungen auf den Grundwasserabfluss (niedriger, mittlerer und hoher Abfluss) in einem großen Karsteinzugsgebiet (schneebeeinflusst, gemäßigtes Klima) in Mitteleuropa auswirken? Die Frage 1 wurde durch Quantifizierung der Sensitivität des Grundwasserstands und der Grundwasserneubildung gegenüber Klimaschwankungen in Australien untersucht. Insgesamt 4350 Messstellen wurden zunächst mit der Zeitreihen-Grundwasser-Toolbox HydroSight modelliert, und 1143 (26%) davon wurden als klimadominierte Messstellen identifiziert. Zur Quantifizierung der Grundwassersensitivität wurde dann ein multipler linearer Regressionsansatz angewandt, der an Studien zur Elastizität von Wasserflüssen adaptiert wurde. Die Ergebnisse zeigen, dass der Grundwasserstand und die Grundwasserneubildung etwa achtmal sensitiver auf Niederschläge reagieren als auf Veränderungen der potenziellen Evapotranspiration. Die inhärenten Eigenschaften der Gebiete, wie Klimatyp und Hydrogeologie, scheinen eine wichtige Rolle bei der Kontrolle der Grundwassersensitivität zu spielen. Die Frage 2 wurde untersucht, indem historische Veränderungen des Grundwasserstands in Australien festgestellt und auf den anthropogenen Klimawandel zurückgeführt wurden. An den vom Klima dominierten Standorten wurde ein Modellierungsexperiment durchgeführt, um die Veränderungen des Grundwasserstands sowohl in der faktischen als auch in der kontrafaktischen (natürlichen) Welt mit und ohne menschlichen Einfluss zu simulieren. Die Ergebnisse zeigen, dass 90% der Standorte seit den 1950er Jahren eine signifikante Grundwasserabsenkung erfahren haben, die auf den anthropogenen Klimawandel zurückzuführen ist. Im Südwesten Australien ist die Abnahme am höchsten und liegt viermal so hoch wie der nationale Median (-74 gegenüber -19 mm pro Jahr). Diese Ergebnisse gehören zu den ersten, die zeigen, dass das Grundwasser bereits seit längerer Zeit den negativen Auswirkungen des anthropogenen Klimawandels leidet. Zur Beantwortung von Frage 3 wurde die Reaktion des Grundwasserabflusses auf Klimawandel und -schwankungen in einem schneebeeinflussten Karsteinzugsgebiet der gemäßigten Breiten (Blautopf) in Süddeutschland zwischen 1952 und 2100 quantifiziert. In dieser Studie wurden statistische Methoden und konzeptionelle Modellierungen eingesetzt, um die langfristigen Auswirkungen zu quantifizieren. Die Ergebnisse zeigen, dass die Veränderungen des jährlichen mittleren und niedrigen Abflusses nicht signifikant waren, aber der jährliche Spitzenabfluss hat sich aufgrund der weniger intensiven Schneeschmelze auf einen niedrigen Wert (< 13,6 m3/s) verschoben. Trotz nicht signifikanter historischer Veränderungen werden alle hoch-, niedrig- und mittleren Abflüsse bis zum Jahr 2100 voraussichtlich abnehmen. Diese Ergebnisse können auf potenzielle Risiken der Wassermangelversorgung an ähnlichen klimatischen und geologischen Standorten hinweisen. Die Quantifizierung der historischen Auswirkungen von Klimawandel und -schwankungen auf das Grundwasser trägt zu einem besseren Verständnis der Reaktion des Grundwassers bei und erhöht die Zuverlässigkeit der Vorhersagen. Nur wenn wir die Vergangenheit verstehen, können wir bessere Vorhersagen für die Zukunft machen.

    Authors: Le, Victoria;

    Um den weltweit wachsenden Energiebedarf zu decken, müssen die Anstrengungen zur Entwicklung hocheffizienter Batteriesysteme verstärkt werden. Die modernste Technologie, die Lithium-Ionen-Batterie (LIB), gilt als unumstritten und ist daher in fast allen mobilen Geräten zu finden. Trotz ihres unbestreitbaren Wertes für die Menschheit sind die Ressourcen an Lithium, Nickel, Kobalt und anderen wesentlichen Elementen begrenzt. Aus diesem Grund stellen metallfreie, organische Batterien einewünschenswerte Alternative dar. Metallorganische Radikalbatterien, die auf nitroxylhaltigen Polymeren wie Poly(2,2,6,6-tetramethylpiperidinyloxymethacrylat) (PTMA) basieren, wurden erstmals 2002 veröffentlicht, und kurz darauf wurde die erste rein organische Radikalbatterie (ORB) vorgestellt. Ein großerNachteil der organischenMaterialien ist allerdings ihre vergleichsweise geringe spezifische Kapazität, da ein großer Anteil ihrer Masse nicht an den elektrochemischen Prozessen beteiligt ist, sondern z.B. der strukturellen Stabilität von Nitroxid-Radikalen dient. Um dieses Problem zu überwinden, wurden neue Klassen von nicht-radikalischen redoxaktiven Polymeren auf der Basis von Cyclopropeniumkationen und Quadratsäureamiden untersucht. Die funktionellen Gruppen bestanden aus den kleinsten molekularen Zyklen (d.h. drei- und viergliedrigen Zyklen), welche aufgrund ihrer aromatischenNatur hohe Redoxpotentiale und Zyklenstabilität aufwiesen. Obwohl beide funktionellen Gruppen seit Jahrzehnten bekannt sind, wurde erst in den letzten Jahren die Anwendung von Cyclopropenium-Kationen als hochpotente Katholyten in Redox-Flow- Batterien (RFBs) untersucht. Soweit wir wissen, sind Quadratsäureamide seit Hünigs grundlegenden elektrochemischen Studien im Jahr 1977 nicht mehr mit dem Fokus auf Batterieanwendungen untersucht worden. Aus diesem Grund wurden neue Polymere synthetisiert, die mit Aminocyclopropeniumkationen (ACPs) und Quadratsäureamidderivaten (SAA), insbesondere Quadratsäurechinoxalinen (SQXs), dekoriert waren. Ihre physikalischen und elektrochemischen Eigenschaften wurden im Hinblick auf ihre Verwendung als organisches Kathodenmaterial für Batterien untersucht. Während die synthetisierten ACP-Polymerverbindungen sehr hygroskopisch waren und irreversible Oxidationen in Lösung unterlaufen sind, stellten sich die SAA-Polymere als vielversprechender heraus. Es konnte demonstriert werden, dass vor allem die SQX-Polymere vorteilhafte Charakteristiken wie eine hohe thermische Stabilität und reversible Redoxeigenschaften in Lösung aufweisen. In nachfolgenden galvanostatischen Zyklisierungen wurde die Leistung von ausgewählten Polymeren in Lithium Halbzellen untersucht. Ein SQX Polymer ist dabei besonders herausgestochen durch seine sehr hohe Zyklisierbarkeit über einhundert Zyklen. Obwohl die erste Entladekapazität (43.7 mAh g−1) deutlich niedriger als die theoretische Kapazität war (66.8 mAh g−1), blieben nach 100 Zyklen 91 % der ersten Entladekapazität (39.8 mAh g−1) erhalten. Es wird erwartet, dass durch weitere Untersuchungen an kritischen Faktoren für die elektrochemischen Eigenschaften diese neuen redoxaktiven SQX Polymere einen signifikanten Beitrag zu der Entwicklung von organischen Batterien leisten werden.

    These 285 documents have been used for the three sections that are part of the results of this article (documents statistics, bibliometric analysis, and literature review statistics). For this purpose, it was necessary to carry out an exhaustive review of the 285 selected documents and to complement this information with the data provided by Scopus. The data-charting process was as follows: the four researchers agreed on the types of data to be extracted, two of them carried out the review while the other two supervised. If any type of data worthy of investigation emerged during the reading, it was discussed, and if appropriate, included, making it an iterative process. For each of the documents, the following variables were collected in a table: author/s, title of the document, year of publication, journal in which it was published, type of document (article or review), number of citations and citations per year, relevance (weighting given by Scopus), DOI, geographical location of researchers, abstract, author keywords and keywords suggested by Scopus, JIF, JCI and H-index information of the journal in which the document is published (with quartiles and percentiles), subject area categories provided by Scopus, territory studied, renewable energy source studied, research technique or methodology used, primary data source used and years collected. In addition, for articles using quantitative techniques, all variables included in each model have been collected.

    Synopsis Climate change can directly and indirectly affect species distribution. Warming may allow for invasive species, such as apple snails, to migrate to higher latitudes where temperatures are more conducive to their survival and invasion success. Higher temperatures and lower pH ranges have been previously documented to affect the form and function of calcium carbonate shells, which serve many functions, including protection from predators and thermoregulation. This study aimed to quantify differences in the morphology and mechanical properties of invasive apple snail, Pomacea maculata, shells after altering temperature and pH. We mechanically tested shells among three five-week treatments: control, higher temperature, and lower pH. Ultimate Strength increased in shells that were exposed to higher temperatures, but Young’s Modulus and Peak Load did not differ among control, temperature, and pH treatments. Apple snails in higher temperature tanks increased their shell length over the five-week trials. Although snail morphometrics did not differ between sexes, male shells exhibited a higher Peak Load, Young’s Modulus, and Ultimate Strength compared to female shells. Our findings are consistent with previous gastropod studies, in that a lower pH is associated with a decrease in shell size, and higher temperatures yield larger snail shells with a higher ultimate strength. Peak Load did not significantly differ among treatments, which suggests that the cross-sectional area is relatively important when considering this species mechanical performance today and in future climates. Due to the intense nutritional and calcium demands of egg production, female snails may be more susceptible to weakened shells due to low pH environments caused by climate change.

    The phenomenon of global change is prompting the implementation of measures aimed at mitigating various effects, with humans being primarily impacted. The objective of this investigation is to analyse the potential self-sufficiency in the built environment through the utilisation of energy generated by photovoltaic systems. These systems have the capacity to reduce or even eliminate the reliance on grid electricity and non-renewable energy sources. The study commences with the delineation of eight neighbourhoods within the city of Madrid, Spain, each characterised by a distinct building typology. In order to ascertain the degree of self-sufficiency, this study calculates the energy production from solar photovoltaic systems installed on rooftops, and then proceeds to assess the energy consumption of each building. The results of the analysis demonstrate the capacity of photovoltaic installations to meet the electricity demands of buildings, such as single-family houses, almost completely, and partially in others, such as multi-family dwellings with multiple units per floor. Furthermore, the impact of differences in building height and urban context on self-sufficiency potential is explored.

    This research investigates the flight behavior of refuse-derived fuel (RDF) in a drop shaft using Computer Vision to obtain statistical data on the aerodynamic properties of the particles. Methods to determine 3D geometry models of complex-shaped particles by photogrammetry and to obtain time resolved particle positions and velocities are described. Furthermore, an approach to obtain the frequency distribution of drag and lift coefficients from photogrammetric analysis and drop shaft experiments is presented. The image evaluation is based on algorithms of the open-source libraries OpenCV, COLMAP as well as MeshLab and Open3D. The precision of the system is validated employing model particles with known geometry. The 3D particle models overestimate the particle surface area by 4.58 %, the position detection works with a mean deviation of 2.73 %. The average sink rate is calculated with an accuracy of 4.87 % and the drag coefficient with an accuracy of 2.08 %. Finally, the frequency distribution of four RDF fractions, namely, textiles, cardboard, 3D plastic particles and 2D plastic foils are presented.

    Authors: Fan, Xinyang;

    Der Klimawandel wird sich voraussichtlich auf das Grundwasser auswirken, aber die Prognosen sind sehr unsicher. Die Quantifizierung der historischen Auswirkungen ermöglicht ein besseres Verständnis der Reaktion des Grundwassers, wurde aber aufgrund des komplexen Einflusses verschiedener Faktoren, wie Grundwasserentnahme für die landwirtschaftliche Bewässerung und Landnutzungsänderungen, nur selten untersucht. Diese Arbeit zielt darauf ab, zum Verständnis und zur Quantifizierung der historischen Auswirkungen von Klimawandel und -schwankungen auf das Grundwasser durch drei miteinander verbundene Forschungsfragen beizutragen: Frage 1: Wie sensitiv reagieren der Grundwasserstand und die Grundwasserneubildung auf Klimaschwankungen in Australien? Frage 2: Wie stark sind die Veränderungen des Grundwasserstands auf den anthropogenen Klimawandel in Australien zurückzuführen und wann haben sich diese Auswirkungen auf das Grundwasser bemerkbar gemacht? Frage 3: Wie haben und werden sich die langfristigen Klimawandel und -schwankungen auf den Grundwasserabfluss (niedriger, mittlerer und hoher Abfluss) in einem großen Karsteinzugsgebiet (schneebeeinflusst, gemäßigtes Klima) in Mitteleuropa auswirken? Die Frage 1 wurde durch Quantifizierung der Sensitivität des Grundwasserstands und der Grundwasserneubildung gegenüber Klimaschwankungen in Australien untersucht. Insgesamt 4350 Messstellen wurden zunächst mit der Zeitreihen-Grundwasser-Toolbox HydroSight modelliert, und 1143 (26%) davon wurden als klimadominierte Messstellen identifiziert. Zur Quantifizierung der Grundwassersensitivität wurde dann ein multipler linearer Regressionsansatz angewandt, der an Studien zur Elastizität von Wasserflüssen adaptiert wurde. Die Ergebnisse zeigen, dass der Grundwasserstand und die Grundwasserneubildung etwa achtmal sensitiver auf Niederschläge reagieren als auf Veränderungen der potenziellen Evapotranspiration. Die inhärenten Eigenschaften der Gebiete, wie Klimatyp und Hydrogeologie, scheinen eine wichtige Rolle bei der Kontrolle der Grundwassersensitivität zu spielen. Die Frage 2 wurde untersucht, indem historische Veränderungen des Grundwasserstands in Australien festgestellt und auf den anthropogenen Klimawandel zurückgeführt wurden. An den vom Klima dominierten Standorten wurde ein Modellierungsexperiment durchgeführt, um die Veränderungen des Grundwasserstands sowohl in der faktischen als auch in der kontrafaktischen (natürlichen) Welt mit und ohne menschlichen Einfluss zu simulieren. Die Ergebnisse zeigen, dass 90% der Standorte seit den 1950er Jahren eine signifikante Grundwasserabsenkung erfahren haben, die auf den anthropogenen Klimawandel zurückzuführen ist. Im Südwesten Australien ist die Abnahme am höchsten und liegt viermal so hoch wie der nationale Median (-74 gegenüber -19 mm pro Jahr). Diese Ergebnisse gehören zu den ersten, die zeigen, dass das Grundwasser bereits seit längerer Zeit den negativen Auswirkungen des anthropogenen Klimawandels leidet. Zur Beantwortung von Frage 3 wurde die Reaktion des Grundwasserabflusses auf Klimawandel und -schwankungen in einem schneebeeinflussten Karsteinzugsgebiet der gemäßigten Breiten (Blautopf) in Süddeutschland zwischen 1952 und 2100 quantifiziert. In dieser Studie wurden statistische Methoden und konzeptionelle Modellierungen eingesetzt, um die langfristigen Auswirkungen zu quantifizieren. Die Ergebnisse zeigen, dass die Veränderungen des jährlichen mittleren und niedrigen Abflusses nicht signifikant waren, aber der jährliche Spitzenabfluss hat sich aufgrund der weniger intensiven Schneeschmelze auf einen niedrigen Wert (< 13,6 m3/s) verschoben. Trotz nicht signifikanter historischer Veränderungen werden alle hoch-, niedrig- und mittleren Abflüsse bis zum Jahr 2100 voraussichtlich abnehmen. Diese Ergebnisse können auf potenzielle Risiken der Wassermangelversorgung an ähnlichen klimatischen und geologischen Standorten hinweisen. Die Quantifizierung der historischen Auswirkungen von Klimawandel und -schwankungen auf das Grundwasser trägt zu einem besseren Verständnis der Reaktion des Grundwassers bei und erhöht die Zuverlässigkeit der Vorhersagen. Nur wenn wir die Vergangenheit verstehen, können wir bessere Vorhersagen für die Zukunft machen.

    Authors: Le, Victoria;

    Um den weltweit wachsenden Energiebedarf zu decken, müssen die Anstrengungen zur Entwicklung hocheffizienter Batteriesysteme verstärkt werden. Die modernste Technologie, die Lithium-Ionen-Batterie (LIB), gilt als unumstritten und ist daher in fast allen mobilen Geräten zu finden. Trotz ihres unbestreitbaren Wertes für die Menschheit sind die Ressourcen an Lithium, Nickel, Kobalt und anderen wesentlichen Elementen begrenzt. Aus diesem Grund stellen metallfreie, organische Batterien einewünschenswerte Alternative dar. Metallorganische Radikalbatterien, die auf nitroxylhaltigen Polymeren wie Poly(2,2,6,6-tetramethylpiperidinyloxymethacrylat) (PTMA) basieren, wurden erstmals 2002 veröffentlicht, und kurz darauf wurde die erste rein organische Radikalbatterie (ORB) vorgestellt. Ein großerNachteil der organischenMaterialien ist allerdings ihre vergleichsweise geringe spezifische Kapazität, da ein großer Anteil ihrer Masse nicht an den elektrochemischen Prozessen beteiligt ist, sondern z.B. der strukturellen Stabilität von Nitroxid-Radikalen dient. Um dieses Problem zu überwinden, wurden neue Klassen von nicht-radikalischen redoxaktiven Polymeren auf der Basis von Cyclopropeniumkationen und Quadratsäureamiden untersucht. Die funktionellen Gruppen bestanden aus den kleinsten molekularen Zyklen (d.h. drei- und viergliedrigen Zyklen), welche aufgrund ihrer aromatischenNatur hohe Redoxpotentiale und Zyklenstabilität aufwiesen. Obwohl beide funktionellen Gruppen seit Jahrzehnten bekannt sind, wurde erst in den letzten Jahren die Anwendung von Cyclopropenium-Kationen als hochpotente Katholyten in Redox-Flow- Batterien (RFBs) untersucht. Soweit wir wissen, sind Quadratsäureamide seit Hünigs grundlegenden elektrochemischen Studien im Jahr 1977 nicht mehr mit dem Fokus auf Batterieanwendungen untersucht worden. Aus diesem Grund wurden neue Polymere synthetisiert, die mit Aminocyclopropeniumkationen (ACPs) und Quadratsäureamidderivaten (SAA), insbesondere Quadratsäurechinoxalinen (SQXs), dekoriert waren. Ihre physikalischen und elektrochemischen Eigenschaften wurden im Hinblick auf ihre Verwendung als organisches Kathodenmaterial für Batterien untersucht. Während die synthetisierten ACP-Polymerverbindungen sehr hygroskopisch waren und irreversible Oxidationen in Lösung unterlaufen sind, stellten sich die SAA-Polymere als vielversprechender heraus. Es konnte demonstriert werden, dass vor allem die SQX-Polymere vorteilhafte Charakteristiken wie eine hohe thermische Stabilität und reversible Redoxeigenschaften in Lösung aufweisen. In nachfolgenden galvanostatischen Zyklisierungen wurde die Leistung von ausgewählten Polymeren in Lithium Halbzellen untersucht. Ein SQX Polymer ist dabei besonders herausgestochen durch seine sehr hohe Zyklisierbarkeit über einhundert Zyklen. Obwohl die erste Entladekapazität (43.7 mAh g−1) deutlich niedriger als die theoretische Kapazität war (66.8 mAh g−1), blieben nach 100 Zyklen 91 % der ersten Entladekapazität (39.8 mAh g−1) erhalten. Es wird erwartet, dass durch weitere Untersuchungen an kritischen Faktoren für die elektrochemischen Eigenschaften diese neuen redoxaktiven SQX Polymere einen signifikanten Beitrag zu der Entwicklung von organischen Batterien leisten werden.
