With the amendment to the German Climate Change Act in 2021, the Federal Government of Germany has set the target to become greenhouse gas neutral by 2045. Reaching this ambitious target requires multisectoral efforts, which in turn calls for interdisciplinary collaboration: the Net-Zero-2050 project of the Helmholtz Climate Initiative serves as an example of successful, interdisciplinary collaboration with the aim of producing valuable recommendations for action to achieve net-zero CO
2 emissions in Germany. To this end, we applied an interdisciplinary approach to combining comprehensive research results from ten German national research centers in the context of carbon neutrality in Germany. In this paper, we present our approach and the method behind the interdisciplinary storylines development, which enabled us to create a common framework between different carbon dioxide removal and avoidance methods and the bigger carbon neutrality context. Thus, the research findings are aggregated into narratives: the two complementary storylines focus on technologies for net-zero CO2 emissions and on different framing conditions for implementing net-zero CO2 measures. Moreover, we outline the Net-Zero-2050 results emerging from the two storylines by presenting the resulting narratives in the context of carbon neutrality in Germany. Aiming at creating insights into how complementary and related expertise can be combined in teams across disciplines, we conclude with the project's lessons learned. This paper sheds light on how to facilitate cooperation between different science disciplines with the purpose of preparing joint research results that can be communicated to a specific audience. Additionally, it provides further evidence that interdisciplinary and diverse research teams are an essential factor for defining solution spaces for complex, interdisciplinary problems.

- Abstract
To reach their net-zero targets, countries will have to compensate hard-to-abate CO2 emissions through carbon dioxide removal (CDR). Yet, current assessments rarely include socio-cultural or institutional aspects or fail to contextualize CDR options for implementation. Here we present a context-specific feasibility assessment of CDR options for the example of Germany. We assess 14 CDR options, including three chemical carbon capture options, six options for bioenergy combined with carbon capture and storage (BECCS), and five options that aim to increase ecosystem carbon uptake. The assessment addresses technological, economic, environmental, institutional, social-cultural and systemic considerations using a traffic-light system to evaluate implementation opportunities and hurdles. We find that in Germany CDR options like cover crops or seagrass restoration currently face comparably low implementation hurdles in terms of technological, economic, or environmental feasibility and low institutional or social opposition but show comparably small CO2 removal potentials. In contrast, some BECCS options that show high CDR potentials face significant techno-economic, societal and institutional hurdles when it comes to the geological storage of CO2. While a combination of CDR options is likely required to meet the net-zero target in Germany, the current climate protection law includes a limited set of options. Our analysis aims to provide comprehensive information on CDR hurdles and possibilities for Germany for use in further research on CDR options, climate, and energy scenario development, as well as an effective decision support basis for various actors. Key Points: - More context-specific assessments of carbon dioxide removal (CDR) options are needed to guide national net-zero decision making - Ecosystem-based CDR options with comparably low implementation hurdles in Germany show relatively small CO2 removal potentials - High CDR potential options in Germany face high in

La présente étude vise à examiner les différents aspects établis par la critique concernant le début du Tristan en prose, à savoir l'histoire des ancêtres du héros éponyme qui relie la famille de Tristan à celle des gardiens du Graal, dont son ancêtre, Sadoc, serait le neveu de Joseph d'Arimathie et le frère d'Helain le Blanc. Cette "préhistoire" a dû subir le jugement inexorable de G. Paris qui n'a su attribuer aucune valeur littéraire à cette partie introductive au roman et la jugeait complètement inutile. La critique a, notamment suite à la publication du premier tome de l'édition par R. L. Curtis en 1963, pris deux positions diamétralement opposées dont un réexamen sera de mise : celle qui n'a pas cessé de défendre l'utilité de la préhistoire pour la suite du roman, car elle est imprégnée, entre autres, de la thématique de l'amour-passion au même titre que le récit tristanien qui s'ensuit. De l'autre côté, de nombreuses études ont montré que la préhistoire, bien qu'elle introduise la thématique du Graal tout au début, n'a aucun impact sur le destin de Tristan, qui est dû à son penchant pour la luxure, exclu a priori de la Quête du Graal qui a lieu plus tard dans le roman. De plus, notre étude montrera d'autres points mis en évidence par la critique ainsi que des perspectives pour la recherche concernant ce sujet : outre la question de l'intertextualité, avec comme modèle principal l'ombre mythique d'Œdipe, et la dominance de Chelinde, l'élément féminin, comme point-pivot de l'histoire, le chantier le plus évident reste le réexamen de la tradition textuelle pour laquelle Curtis avait, jadis, établi un stemma, mais dont la méthodologie est aujourd'hui dépassée. Ainsi, nous espérons qu'un jour il sera possible, grâce à un classement des manuscrits obtenu par des méthodes plus opérables pour le traitement des textes en prose, de pouvoir apporter de nouvelles connaissances de la genèse d'au moins une partie de cette œuvre littéraire très vaste.

- Abstract
The wood-water interactions of modified beech wood (Fagus sylvatica L.) were studied. Specimens were thermally modified at 180 (TM1), 200 (TM2) and 220 degrees C (TM3), acetylated (Acet), and melamine formaldehyde (MF) resin (Mel) modified. Afterwards, the water vapour characteristics, i.e. water vapour sorption isotherms, equilibrium moisture content (EMC), dimensional stability of specimens conditioned at 30, 65 and 90% RH and liquid water characteristics, i.e. water absorption, maximum moisture content (MC), leachability and swelling kinetics, were determined and the results compared with reference (Ref) specimens. From the results, it is evident that the scale of wood-water interactions was highly dependent on the thermal modification temperature and type of chemical modification. The water vapour isotherms of thermally modified wood decreased, whereas more severe treatment exhibited more distinct reduction. The EMC values of the Mel and TM1 specimens decreased only at high RH, whereas the most significant decrease, within the whole range of observation, was found in the Acet group. The maximum MC reduction was achieved by acetylation. As a consequence of swelling reduction, dimensional stability expressed as anti-swelling efficiency (ASE) was considerably improved. A relatively high initial linear-phase swelling rate was found for the Ref specimens, whereas modified wood exhibited comparatively slow and gradual swelling.

- Abstract
In its latest assessment report the IPCC stresses the need for carbon dioxide removal (CDR) to counterbalance residual emissions to achieve net zero carbon dioxide or greenhouse gas emissions. There are currently a wide variety of CDR measures available. Their potential and feasibility, however, depends on context specific conditions, as among others biophysical site characteristics, or availability of infrastructure and resources. In our study, we selected 13 CDR concepts which we present in the form of exemplary CDR units described in dedicated fact sheets. They cover technical CO2 removal (two concepts of direct air carbon capture), hybrid solutions (six bioenergy with carbon capture technologies) and five options for natural sink enhancement. Our estimates for their CO2 removal potentials in 2050 range from 0.06 to 30 million tons of CO2, depending on the option. Ten of the 13 CDR concepts provide technical removal potentials higher than 1 million tons of CO2 per year. To better understand the potential contribution of analyzed CDR options to reaching net-zero CO2 emissions, we compare our results with the current CO2 emissions and potential residual CO2 emissions in 2050 in Germany. To complement the necessary information on technology-based and hybrid options, we also provide an overview on possible solutions for CO2 storage for Germany. Taking biophysical conditions and infrastructure into account, northern Germany seems a preferable area for deployment of many concepts. However, for their successful implementation further socio-economic analysis, clear regulations, and policy incentives are necessary.

- Abstract
Germany 2050: For the first time Germany reached a balance between its sources of anthropogenic CO2 to the atmosphere and newly created anthropogenic sinks. This backcasting study presents a fictional future in which this goal was achieved by avoiding (∼645 Mt CO2), reducing (∼50 Mt CO2) and removing (∼60 Mt CO2) carbon emissions. This meant substantial transformation of the energy system, increasing energy efficiency, sector coupling, and electrification, energy storage solutions including synthetic energy carriers, sector-specific solutions for industry, transport, and agriculture, as well as natural-sink enhancement and technological carbon dioxide options. All of the above was necessary to achieve a net-zero CO2 system for Germany by 2050.

Germany 2050: For the first time Germany reached a balance between its sources of anthropogenic CO2 to the atmosphere and newly created anthropogenic sinks. This backcasting study presents a fictional future in which this goal was achieved by avoiding (∼645 Mt CO2), reducing (∼50 Mt CO2) and removing (∼60 Mt CO2) carbon emissions. This meant substantial transformation of the energy system, increasing energy efficiency, sector coupling, and electrification, energy storage solutions including synthetic energy carriers, sector‐specific solutions for industry, transport, and agriculture, as well as natural‐sink enhancement and technological carbon dioxide options. All of the above was necessary to achieve a net‐zero CO2 system for Germany by 2050. Plain Language Summary: Here a net‐zero‐2050 Germany is envisioned by combining analysis from an energy‐system model with insights into approaches that allow for a higher carbon circularity in the German system, and first results from assessments of national carbon dioxide removal potentials. A back‐casting perspective is applied on how net‐zero Germany could look like in 2050. We are looking back from 2050, and analyzing how Germany for the first time reached a balance between its sources of CO2 to the atmosphere and the anthropogenic sinks created. This would consider full decarbonization in the entire energy sector and being entirely emission‐free by 2050 within three priorities identified as being the most useful strategies for achieving net‐zero: (a) Avoiding‐ (b) Reducing‐ (c) Removing emissions. This work is a collaboration of interdisciplinary scientists with the Net‐Zero‐2050 cluster of the Helmholtz Climate Initiative HI‐CAM. Key Points: The net‐zero system shows that for countries like Germany, avoiding CO2 emissions was the largest contribution to achieve net‐zero CO2With the three strategies of emissions avoidance, reduction, and removal, Germany has achieved its net‐zero CO2 goal for the first timeIn addition, to natural sink enhancement carbon dioxide removal (CDR) options, technological CDR measures combined with geological CO2 storage were necessary to reach net‐zero CO2 [ABSTRACT FROM AUTHOR]

This thesis examines the influence of microwave pretreatment of wood modification and Bethell impregnation methods on the treatability of Norway spruce (Picea abies) in consideration with its mechanical properties. The aim of this work was to establish the intake of impregnants (preservatives) and the depth of penetration in transverse direction of each treatment group with impregnated specimens. Further experimental examinations that were focused on the assessment of mechanical wood properties and the comparison with references (non-impregnated specimens) followed. Results showed that the intake of impregnants and the depth of penetration increases with time (modification) of the impregnation treatment. In contrast, microwave wood treatment actually decreases those values. Neither microwave modification nor adjustment of impregnation method had an influence on mechanical wood properties.

The bachelor thesis presents a comparison of mass loss and moisture content of samples from Norway spruce (Picea abies), that were dried by different proces -- natural air drying and microwave drying.. All of samples were degraded by wood-destroying brown rot fungi -- Serpula lacrymans -- in the range from two to twelve weeks. Measurements were made every fourteen days. At the end of experiment several samples were selected for the production of microscopical slides, on which one can observe the progressive degradation of the cell wall of spruce wood. The measurements show that the use of microwaves radiation output of 2 kW has a minimal influence on the fungi spread rate and wood degradation. The highest difference was measured after eight weeks, the average mass loss of microwave dried samples was 25.41%, while in natural dried samples only 23.54%.

- Abstract
La présente étude vise à examiner les différents aspects établis par la critique concernant le début du Tristan en prose, à savoir l'histoire des ancêtres du héros éponyme qui relie la famille de Tristan à celle des gardiens du Graal, dont son ancêtre, Sadoc, serait le neveu de Joseph d'Arimathie et le frère d'Helain le Blanc. Cette "préhistoire" a dû subir le jugement inexorable de G. Paris qui n'a su attribuer aucune valeur littéraire à cette partie introductive au roman et la jugeait complètement inutile. La critique a, notamment suite à la publication du premier tome de l'édition par R. L. Curtis en 1963, pris deux positions diamétralement opposées dont un réexamen sera de mise : celle qui n'a pas cessé de défendre l'utilité de la préhistoire pour la suite du roman, car elle est imprégnée, entre autres, de la thématique de l'amour-passion au même titre que le récit tristanien qui s'ensuit. De l'autre côté, de nombreuses études ont montré que la préhistoire, bien qu'elle introduise la thématique du Graal tout au début, n'a aucun impact sur le destin de Tristan, qui est dû à son penchant pour la luxure, exclu a priori de la Quête du Graal qui a lieu plus tard dans le roman. De plus, notre étude montrera d'autres points mis en évidence par la critique ainsi que des perspectives pour la recherche concernant ce sujet : outre la question de l'intertextualité, avec comme modèle principal l'ombre mythique d'Œdipe, et la dominance de Chelinde, l'élément féminin, comme point-pivot de l'histoire, le chantier le plus évident reste le réexamen de la tradition textuelle pour laquelle Curtis avait, jadis, établi un stemma, mais dont la méthodologie est aujourd'hui dépassée. Ainsi, nous espérons qu'un jour il sera possible, grâce à un classement des manuscrits obtenu par des méthodes plus opérables pour le traitement des textes en prose, de pouvoir apporter de nouvelles connaissances de la genèse d'au moins une partie de cette œuvre littéraire très vaste.
