In the pursuit of more secure information transfer, advanced nanoelectronic technologies and nanomaterials must be developed. Here, we present a material able to undergo an unprecedented light-pumped directional charge transfer process reminiscent of toppling dominoes. The material is based on ortho-fluorinated azobenzene molecules which are organized in molecular rows by the regular array of a metal-organic framework. The azobenzene molecules undergo light-induced transcis forward as well as electrocatalytic cistrans backward isomerization. Our findings reveal that electron hopping occurs in a sequential and propagating manner between the light-generated cis isomers along with an isomerization of the sample to the trans state. Thus, light can be used to locally write information, which subsequently can be read out by the transferred charge with simultaneous deletion of the information. This freely repeatable, self-erasing domino information transfer is a groundbreaking new mechanism to process information on the molecular level that may find application in encryption.

It accompanies the paper Hardt et al. (submitted to Archäologische Forschungen in Afrika in March 2025): Ancient routes of interaction in the historical sultanate of Tadjoura - results of two geoarcheological and ethnohistorical research seasons in 2023 and 2024

The data published here come from sediments sampled within archaeological structures and are used for their detailed description and dating. For radiocarbon dating, charcoal or other organic fragments were extracted from the sediment by floatation. The dating was carried out at the Poznan Radiocarbon Lab via AMS. The sedimentological parameters include grain size distribution curves based on laser diffraction measurements (3 measurements per sample; Beckman Coulter LS 13320) and raw data of the elemental composition obtained by a portable energy-dispersive X-ray fluorescence (XRF) spectrometer (Thermoscientific Niton XLt3). Sedimentological works were carried out in the laboratory for Physical Geography at Freie Universität Berlin. The preparation steps followed the standard laboratory procedure (cf. Hardt et al., 2023; doi.org/10.5194/egqsj-72-37-2023).

The raw XRF data include measurements of the following standard material that can be used for calibration: RF25 => NCS DC 73325 Soil, China National Analysis Center for Iron and Steel (2008) RF87 => NCS DC 73387 Soil, China National Analysis Center for Iron and Steel (2008) RF89 => NCS DC 73389 Soil, China National Analysis Center for Iron and Steel (2008)

The spin-crossover (SCO) properties of the dinuclear complex [{Fe(H2B(pz)2)2}2μ−(ac(bipy)2)] were studied as (sub)-monolayer and thin film deposited by an ultra-high vacuum liquid-jet deposition technique on highly oriented pyrolytic graphite (HOPG) by X-ray absorption spectroscopy. A comparison of the SCO properties of thin films and a dropcast sample indicates that the spin-switching probability of the thin films is limited due to substrate–molecule interactions. The maximum percentage of molecules in the low-spin (LS) state observed for 0.7 and 1.8 monolayers (ML) is approximately 43 % at a temperature of 80 K in comparison to the dropcast sample where ≈ 66 % of the complex is in the LS state. The similar switching properties of the dropcast sample as of a bulk powder sample confirm that the SCO properties are not affected by the presence of solvent necessary for deposition. The soft-X-ray-induced excited spin-state trapping (SOXIESST) effect is pronounced in all samples, although the light-induced high-spin (HS) fraction of the dropcast and the thin-film samples on HOPG is higher as compared to the HS fraction attained by SOXIESST, which confirms the sensitivity of the complex to light.

This dataset presents detailed coverage information derived from catalogs of CO₂ jet deposit features—fans and blotches—observed at the Martian South Pole. Generated using high-resolution HiRISE imagery from the Mars Reconnaissance Orbiter (MRO), the dataset quantifies the spatial extent and distribution of these seasonal deposits across multiple Martian years. The coverage data is crucial for understanding the dynamics of CO₂ sublimation and its interaction with surface and atmospheric processes.

The coverage metrics were calculated from annotated features compiled through contributions from the citizen science project Planet Four and advanced clustering algorithms. Each dataset entry includes coverage percentages, and the tile and image identifiers. The data spans several key regions of interest, providing insights into Martian polar processes.

This coverage dataset is a valuable resource for planetary scientists, climate modelers, and researchers focused on Martian seasonal dynamics and atmospheric coupling.

This dataset comprises comprehensive catalogs of CO₂ jet deposit features—fans and blotches—captured at the Martian South Pole. Derived from High-Resolution Imaging Science Experiment (HiRISE) imagery onboard the Mars Reconnaissance Orbiter (MRO), the catalogs were developed as part of a thesis exploring seasonal sublimation-driven processes and their implications for Martian surface-atmosphere interactions. The data was created through an extensive workflow, including contributions from the citizen science project Planet Four, advanced density-based clustering (DBSCAN), and ground-projection techniques to generate geographic coordinates. Each entry includes detailed metadata such as location, morphology, orientation, and classification into either fan or blotch types. Additionally, we also provide multiple catalogs including more metadata. The dataset serves as a vital resource for planetary scientists, atmospheric modelers, and researchers studying Martian polar dynamics. It provides foundational data for investigating surface-atmosphere coupling, wind patterns, and the spatial-temporal behavior of seasonal CO₂ jet deposits.

This CSV file records the search results for terms "etat AND armes" and "etat AND artillerie" (condition/inventory AND weapons, condition/inventory AND artillery) from documents relating to the Caribbean, Louisiana and Guyana colonies of the First Colonial Empire collection, held at the French Archives nationales d'outremer (Overseas archives). The results range from 1675 to 1815. The file records the search term, archive directory and code of the record, date of the record, kind of record, title, and availability online. It then records whether the record includes any remarks on the condition of weapons/artillery (as opposed to simply recording numbers), and if so whether problems are noted, whether those noted problems are related to decay or climate, and finally whether mention is specifically made of rust/oxidisation. This data is intended to support the RUSTEE project; specifically, research into how the claims made in travel narratives about the problems with rusting equipment in different climates (Ligon 1673, Ellis 1748) are or are not reflected in routine colonial administrative correspondance in France's equatorial American colonies. It should also be useful to researchers interested more generally in the role of the island environment, climate and weather in European colonial projects.

The dataset contains shape-files of the valleys and deltas in the Jezero crater on Mars: 1) initial and last incision valleys for the western inlet, northern inlet and outlet; 2) minimum, medium and maximum extents of the western and northern deltas. The mapping was done in ArcGIS 10.8.2 using CTX and HiRISE data (Planetary Data System Imaging Node https://pds-874 imaging.jpl.nasa.gov/) and HRSC data (data archives of ESA and NASA and https://maps.planet.fu-berlin.de [Walter et al., 2018]). For the minimum extent of the western delta a GIS version of the map of [Stack et al., 2020] was used. Details of mapping are described in [Ovchinnikova A. et al. A modeling approach for water and sediment transport in Jezero crater on Mars based on new geomorphological evidence. Icarus (accepted)].

Field work and sampling were funded by the German Academic Exchange Service (DAAD), Grant 57137675. The sample analysis was funded by the German Research Foundation (DFG), Grant BO 659/28-1, project-no. 424056024.

The dataset is related to the Horizon 2020 Una.Resin project Work Package 1 mapping exercise (Task 1.2) on Research & Innovation (R&I) strategies and strategic initiatives. This task was carried out from February to August 2021 by the University of Helsinki and Freie Universität Berlin. Questionnaire was targeted at the research professionals and policymakers at each of the eight Una Europa universities participating in the project (University of Edinburgh; University of Helsinki; University of Bologna; Complutense University of Madrid; Freie University Berlin; 3 Katholieke Universiteit Leuven; Jagiellonian University; Université Paris 1 Panthéon-Sorbonne) aiming to identify the complementary strengths, values, opportunities and barriers for the building the capacities for research collaboration in this alliance. Questionnaire helped us to understand specifically the university level strategic research themes or areas / thematic priorities, areas of excellence, multidisciplinary structures, strategic partnerships and the universities’ codes of conduct or other value-based regulations. The benchmarking served as a groundwork for development of the Una Europa R&I strategy that was launched in November 2023. Task was conducted together with the WP2 colleagues, who prepared the second part of the questionnaire benchmarking the existing strategies, policies and initiatives on research infrastructures. The WP2 has provided a separate dataset presenting the part 2 answers and curated by the University of Bologna. This dataset is available by request: a.franchini@unibo.it.

This data set contains new results on how organisations can capture sustainability and manage innovation to contribute to changes in socio-technical systems characterised by greater sustainability. While drawing from sustainability transitions research can help to establish sustainability criteria that innovative organisations must meet with their sustainable innovation practices to contribute to complex and long-term sustainability, it is also essential to assess the governance and decision-making of innovative organisations within sectors in more detail. By doing so, we can identify potential adaptations that could make these organisations facilitators of sustainable transformational changes in the real world. Research in the field of innovation management (IM) provides significant insights into the driving forces behind sustainable innovation (SI). Management studies that focus on the management of sustainable innovation draw attention to the necessary measures to align development with sustainability and the role of innovation in facilitating business transitions to sustainable practices. However, challenges emerge when it comes to linking innovation initiatives with potential risks or consequences that can emerge, e.g., by pursuing environmental, yet socially unjust, goals and providing management practices for their prevention. This is partly due to conceptual limitations and the applied methods in prevailing studies. In this light, it can be beneficial to look at the Responsible Research and Innovation (RRI) literature. As there is still little research exploring conceptual integrations of the two approaches for innovation management to answer transitions-related research questions, it will be first explored in this doctoral thesis, how RRI can expand existing knowledge on the management of sustainable innovation to prevent "partially" sustainable transitions. Second, it will be investigated how RRI could facilitate novel innovation management approaches to address transitions-related research questions. In Chapter 2, the impact of sustainability agendas in research and innovation on transitions is assessed to make conceptual extensions using the four RRI principles. A primary focus is on the concept of sustainable innovation, which provides essential features to analyse innovation processes in terms of their broader implications on socio-technical systems. However, SI falls short in addressing multidimensional sustainability, such as responsibility for potential future trade-offs or consequences of innovation. In such cases, innovation may run the risk of intervening in transitions with solutions that might be more environmentally friendly yet socially unjust. Therefore, the question is raised how innovation can be managed to contribute to creating sustainable socio-technical systems? To address this research question, answers are sought in the RRI literature, which encourages thinking about the purpose of research and innovation, the underlying goals of innovation, and the ethical, inclusive, and democratic opportunities through which these goals can be achieved. Specifically, the Chapter provides findings from a systematic literature review (SLR) of a representative sample of empirical studies from the SI and RRI literature (n=29). In the initial phase of the analysis, the SLR aims to enhance our understanding of aspects highlighted in the SI literature that enable sustainability-driven innovation processes to contribute to sustainable socio-technical system change and limitations highlighted in the same literature that may weaken the sustainable contributions. In the second part of the analysis, it is investigated how each RRI principle can support innovation processes for sustainability, either by enhancing existing strengths or minimising existing weaknesses. While findings from SI publications underscore certain strengths, such as aligning economic profit with sustainability goals, weaknesses also emerge. Specifically, profit, competitiveness and technology-centric assessments often take precedence over social sustainability. Nevertheless, the RRI publications illustrate that the RRI principles can contribute to enhancing existing strengths, e.g., by reinforcing corporate codes of conduct to enhance decision-making for social sustainability. Furthermore, RRI proves to be advantageous in addressing current challenges, e.g., by recognising sustainability-dilemmas at an early stage in order to integrate solution-finding into strategy-development. This not only contributes to the existing literature by synthesising two innovation-driven concepts in a novel form but also expands upon these requirements by providing a first critical discussion of responsible approaches in innovation processes for sustainability and useful methods to support sustainable change. In Chapter 3, Foresight is considered an essential approach to support sustainable change with responsible approaches to innovation by enabling deliberations on complex futures. However, even though Foresight provides valuable analytical and outlook tools to address this task, Foresight-related methods need to be tailor-made and fine-tuned to accomplish it adequately. It can be argued that Foresight inherits open potentials for capturing the multidimensional nature of sustainability in innovation, i.e., by omitting broader visions and focussing more on technical elements or by superficially considering complex interrelationships for subsequent decision-making. In Chapter 3, the aim is to answer the question of how Foresight methods can be adapted to explore how innovation-driven systemic changes can contribute to greater (multidimensional) sustainability and how RRI can assist in this task? Thereupon, a responsibility-oriented Foresight approach with a Delphi method is developed and piloted in Chapter 3. Using a multi-stage Delphi survey informed by insights from the RRI literature, 52 public and private sector experts are asked to examine 15 innovation-driven future changes in the German agri-food system for which there was a shared opinion that they represent (potential) sustainable changes. For the Delphi questionnaire, RRI provides an approach to assessing (multidimensional) sustainability from a broader perspective, allowing co-existing values to sharpen the complexity of future expectations. The analysis reveals that the Delphi method can be adapted to enable reflection on unintended consequences of "seemingly-sustainable", innovation-driven future changes for multiple aspects of sustainability. This can be a beneficial addition to previous studies by providing a methodological framework for the reassessment of promising innovation for sustainable transition in light of system complexities. While consensus can be reached on the most desirable innovation-driven changes, it becomes evident that significant and interrelated risks for sustainability are associated with more and less desirable changes. Thereby, future options that are assessed to be desirable by the experts, such as the introduction of a nutrient-rich diet in school canteens and cafeterias, still face severe risks for certain dimensions of sustainability. Thereby, socio-cultural or socio-economic backgrounds define access, which can result in a social divide. Similar assessments are still rare in connection with Foresight, especially in connection with Delphi surveys. Additionally, by examining the reasons for experts’ dissent, it becomes evident that the desirability of future options for a sustainable agri-food system largely depends on the interplays with other innovations or consumption and production patterns. While Chapter 3 offers recommendations on how Foresight processes can be employed to inform innovation-driven systemic changes and contribute to greater multidimensional sustainability from a management perspective, similar to other studies, the primary focus lies on anticipating impacts, involving a broad spectrum of stakeholders, and fostering reflexivity in research agendas. However, a notable gap remains in understanding how to ensure that the generated future knowledge is effectively responded to during subsequent decision-making and planning processes. Thereby, anticipated knowledge may not be translated into responsive strategy-development, compromising the governance of societal challenges in desirable ways. Additionally, despite awareness of potential contrasted future options, there remains a risk that future options with divergent characteristics are addressed less comprehensively in Delphi surveys, thus, effecting their implications for subsequent decision-making. Consequently, the Delphi as a well-established methodological tool to inform subsequent decision-making and planning processes is utilised to integrate the articulation of response options for subsequent strategy-building. Specifically, in Chapter 4, the focus is on how a Delphi can inform research and innovation about responsive strategy-building to contribute to the creation of new procedures, structures, and institutional settings that promote beneficial outcomes and prevent harm? Drawing from the RRI literature to understand discrepancies between "desirability" and "probability" of future options as missed opportunities to increase social desirability ("doing good") or as threats to it ("avoiding harm"), experts (n=21) who have taken part in the previous two rounds were engaged in an additional third-round to assess three innovation-driven changes in the German agri-food sector that are characterised by desirability and probability discrepancies and their risks to sustainability. To increase alignment with the responsiveness principle, they were tasked with identifying and making potential future response options for research and innovation more explicit to help future decision-makers find or adopt strategies that promote beneficial outcomes and prevent harm to the society, environment and economy in an equitable manner. The discussion in Chapter 4 presents a novel perspective on assessing sustainability issues from an innovation management standpoint when compared to related literature by presenting the sustainability prospects of future options in connection with their management. The results show that the Delphi method can be adapted to contribute to responsiveness in future decision-making, ultimately improving the overall sustainability prospects of certain innovation-driven future changes. However, the results also demonstrate that despite a willingness to adapt, innovative organisations can be constrained by existing operational frameworks, which limits their ability to prevent social, environmental and economic harm. Hence, a methodological framework is presented that can help researchers deal with critical questions for transformative change seriously and how this can provide valuable insights for subsequent strategy-development and planning by elucidating response options without losing sight of the systemic context within which innovative organisations operate. The insights from Chapter 3 also inform Chapter 5 by combining it with a business modelling process. Business modelling allows for the visualisation and incorporation of existing knowledge to make strategic decisions that influence how businesses create, deliver, and capture value in the future. In Chapter 5, the goal is to gain a deeper understanding of how business model processes can be inspired to implement research behaviour that constitutes "doing good" and "avoiding harm" in the future, e.g., by elaborating on new options for partner selection or value proposition, as one opportunity to depart from business-as-usual strategies and the formation of more sustainable modes of production and consumption? Business modelling activities often lack clear insights into the practical application of business models in the future and multidimensional sustainability, with environmental and social aspects taking precedence, while other dimensions like human rights, health, or safety receive less consideration. These are just some examples why current business modelling applications run the risk of overlooking several crucial aspects required for a sustainable contribution to transition through strategic decision-making. In response to these challenges, a responsible business modelling approach is developed and piloted with a heterogeneous group of researchers and innovators from the German agri-food sector. The process includes a Value Proposition and a BMC workshop with researchers and innovators from the German agri-food sector (n=15) that utilises results from Chapter 3 in combination with additional RRI-interventions to inform three preselected business model ideas about novel food innovations. This approach represents an initial attempt to integrate future knowledge from various sources and viewpoints more closely into the value creation and delivery process of businesses in an iterative manner. The results demonstrate that the interventions can inspire new directions for doing business in the future by fostering anticipation, reflexivity and responsiveness, ultimately adding sustainability characteristics to the BMs, such as by reinforcing more sustainable linkages in network creations or mitigate risks associated with harmful ones. Additionally, it demonstrates that anticipative and reflective behaviour does not necessarily lead to responsive behaviour. Instead, not all broadly configured knowledge had an impact on the shapes of the final BMs, which extends the implications for responsible innovation approaches.
