Project Title: Analyzing the Circular Economy of the Metal and Mineral Resources for Large-Scale Implementation of Green Hydrogen Technology

Large-scale deployment of clean energy technologies will require a considerable amount of materials. The surge in demand for critical metals related to emerging energy technologies may hinder the energy transition. In this project, we will analyze the material flows when upscaling green hydrogen technology. We will conduct a quantitative review of the material requirements of green hydrogen technologies and provide an analysis of detailed data including material intensity. Besides providing a large amount of structured quantitative data, we will (1) research the demand for green hydrogen technology-related metals; (2) foresee material constraints of large-scale implementation of green hydrogen and the secure and responsible supply of these materials; (3) identify changes in metal intensity caused by technological development and material requirements for non-critical components, which are important but often overlooked.

Project Title: Innovations in Environmental Law: Rights of Nature, Climate Litigation and Protection of Environmental Defenders

This project examines the contemporary diversity of legal proposals for dealing with ecological problems from a comparative and co-productive perspective. Three innovative topics in environmental contemporary law will be specially considered:
i) the relevance of a movement recognizing the rights of nature,
ii) the characteristics of emerging climate litigation,
iii) the incorporation of the environmental defenders as a figure that requires legal protection.

All those interrelated topics have gained momentum in several Latin American countries as well as other latitudes, for example, New Zealand, Australia or India in the last years and have inspired Western-style legal orders in the Global North to rethink their anthropocentric regulation on the protection of the environment.

Project Title: Unfolding the Early Modern Page: Transformations in Print and Paper

Unfolding the Early Modern Page examines innovations in print culture that altered the reader’s relationship to the book: the paper fold; the circular dial or volvelle; the use and abuse of ink; and the blank space. Privileging formal aspects of the page over intellectual disciplinary boundaries reveals how medium influenced message. I pursue book history as an entry-point into understanding how readers made knowledge by physically interacting with books, in ways that would be lost once printing practices and reading conventions changed with the advent of mass production. How did early modern literature and its readers deal with these “paper bodies”? How does modern cognitive science approach sea changes in the mental act of reading? Among the first to unite modern and pre-modern ideas about how early interactive texts helped shape the production of knowledge, my book contributes to the impetus in literary study to rethink culture from materiality upwards.

Project Title: EXAFS Investigation of LiNiO2 during charge

LiNiO2 is a promising positive electrode material for Li-ion batteries. Despite many years of development, it still is not commercialised due to the difficult synthesis and chemical, electrochemical and thermal instabilities. In particular, the degradation mechanisms that occur at the end of charge, when all Li is deintercalated, are severe and still need to be better understood. We have performed in situ (during charge) x-ray absorption spectroscopy measurement to determine the local coordination of Ni in LiNiO2 during charge. In the course of this project, advanced and detailed data analysis will be employed in collaboration to treat the data and highlight the behaviour of the material.

Project Title: “Sustainability Assessment of Future Battery Material Life Cycles”

Batteries are one of the fastest growing markets globally with highest importance in the transport sector, portable electronics, and grid storage. The building up of the in-use stock for batteries raises concern of  severe supply risks for critical raw materials and an accumulation of a new electronic waste stream. By combining Life Cycle Assessment and Material Flow Analysis research, the research project develops assessment methods on the criticality and circularity of future battery material life cycles. We model the development of geopolitical risks in battery material life cycles and the impact of continued growth of the battery market on lifetimes of metals in the global economy.

Project Title: Self-reporting Mechanochromic Fibre Reinforced Composites Enabled by AIEgens

To reduce the time, material, and labour cost associated with the maintenance efforts towards inspection and replacement of damaged structural components, extensive research has been dedicated to the development of methods for structural health monitoring and early detection of damage in load-bearing composite structures. The main aim of this project is to develop self-reporting composites enabling autonomous damage detection for improved safety and reliability of critical structural components. With the aggregation-induced emission (AIE) luminogens (AIEgens) introduced, the mechanical damage of the thermoset epoxies and their fibre reinforced composites that triggers rapid generation of a local fluorescence signal, can be conveniently visualized under a certain excitation light with excellent sensitivity and high contrast.

Project Title: Computational Design of Artificial Enzymes from De Novo Protein Scaffolds

Enzymes are the most efficient catalysts known. They can accelerate chemical reactions by up to 26 orders of magnitude, display unmatched selectivity, and are completely biodegradable. Given their incredible potential for chemical synthesis, enzymes are in high demand for numerous applications in industry. However, the finite repertoire of naturally occurring enzyme activities restricts their applicability to only a small fraction of all desired applications. If we could design, from scratch, artificial enzymes that could catalyze any reaction with high efficiency, it would open the door to highly valuable biotechnologies. The goal of this short-term visit is to establish a research collaboration that will combine Prof. Birte Höcker’s expertise in de novo protein design with my expertise in ensemble-based enzyme design to create more efficient artificial enzymes than previously possible.

Project Title: The Meta-discourse of Online Eating in the News

Bringing together corpus linguistics and qualitative discourse analysis, the aim of this cooperation is to study the meta-discourse of online eating, commonly known as mukbang, through corpora of newspaper articles reporting on this phenomenon. Mukbang, originated from the Korean internet, is a livestream where a host eats and viewers watch them eating, while interacting with each other in real time. The project investigates how the news talks about and disseminates mukbang, and what constitutes the meta-discursive context of mukbang. The collaborative work will thus put forward the idea that mukbang is a discursive construct of food experience in the digital age.

Project Title: Fabrication of customisable graphene sensors for biomedical applications

It is estimated that current biosensor materials would need to be significantly more efficient to be suitable for accurate early stage diagnosis of irreversibly progressive neurodegenerative health conditions. Novel sensor designs using graphene offer feasible solutions to construct extremely sensitive and rapidly responsive materials to exceed the required performance. Driven by our recent developments in hybrid material design, process control and sensor fabrication, with this collaborative grant we shall further establish experimental verification of designs of customisable graphene sensors with high accuracy for biomedical applications.

Project Title: Synthesis and Characterization of Iridium-Decorated Titanium Oxynitride Supported on Nanocarbon (Ir/TiONx@NCF) for Water splitting

Hydrogen is regarded as the future fuel and global production currently stands at 70 million ton/year. A Proton exchange membrane water electrolyzer (PEMWE), which has the ability for fast load change, high power and energy efficiency, and high gas purity uses expensive catalysts at the anode (OER) and the cathode (HER) side. The cathode requires ca. 0.5 – 1 mg Pt/cm2, the anode requires 2 mg Ir/cm2. However, the scarcity and high cost of this precious metal are challenges for sustainable development of PEMWEs. The areas on which research needs to focus are: (1) enhanced intrinsic activity of the catalysts by material design and (2) advanced electrode morphologies and cell configurations. The OER, which is a complex four electron process with a very high thermodynamical potential (1.23 V) during water splitting is more challenging. Iridium used for OER are either metallic Ir nanoparticles or IrO2. But during OER, it gets oxidized to amorphous IrOx. Ir with 3+ oxidation state was found to be more active. Hence catalyst design with more number of Ir(III) will enhance the reaction rate. But the stability of Ir(III) based catalyst is questionable. But with a proper support material, the stability and durability of the catalyst can be enhanced. Thus, the project was to fine tune Ir based electrocatalyst with carbon nanostructures to arrest the corrosion during continuous operation and to improve the stability and activity of OER electrocatalysis.

Project Title: Responsibility and Impact of Multinational Food Corporations on Public Health Nutrition in Ghana

The responsibility and impact of multinational food corporations in emerging economies, particularly on the nutrition transition, has long been an important public health issue. The extent to which food corporations consider public health and nutrition issues in emerging economies as part of their corporate social responsibility initiatives and their potential impact is a neglected area of research. This interdisciplinary research aims to assess how food corporations understand and implement their role and responsibility for food, nutrition, and health in developing countries, using Ghana as an example, and will develop a conceptual model that identifies different impact areas. The study will further demonstrate and critically assess the impact of food, health, and nutrition-related corporate social responsibility measures on public health nutrition in Ghana using experimental designs and to derive concrete action measures for business, public health nutrition policy and society.

Project Title: Climatic forcing of global ecosystem changes from the Last Glacial Maximum to the end of the 21st century

Safeguarding biodiversity during the Anthropocene requires robust forecasts of how climatic changes will change ecosystems. The project addresses this by developing new metrics of ecosystem change: velocity vectors of phytoclimatic change. These new metrics of ecosystem change represent how fast growth forms would have to migrate to assemble the same ecosystem elsewhere in a future climate. We are building these new metrics by combining modelling work done by the researchers at Plant sciences at Bayreuth, translating climatic combinations into phytoclimates (e.g., the climate’s suitability for plant growth forms that characterize ecosystem identity), and the statistical tools developed by dr. Ordonez for computing climatic velocity and its components driving ecosystem disaggregation and reassembly. We are using these metrics of ecosystem change to assess when and how novel vegetation assemblages emerged over the late Pleistocene climate transition and where these will arise by the end of the 21st century.

Project Title: Influence of changing temperature patterns on the rock strength

Climate change will affect temperature and moisture regimes in mid-latitude regions such as Bavaria and Czechia. Previous studies suggest that warmer and wetter climates will accelerate rock weathering. This should affect the current rockfall hazard as it was already observed. However, there is a lack of data that directly quantifies the influence of temperature and climate change-induced temperature change on rock strength. This short-term project aims to answer the important question: How much will change in moisture and temperature amplify the rock weathering? A series of controlled temperature loadings will be performed on selected rock samples from a mild climate of Central Czechia under dry and saturated conditions. During the loading, automatic ERT, TDR and AE sensors will be used to monitor moisture and cracking of the samples. This will be followed by sample testing to analyse changes in the rock strength.

Project Title: Sustainability, Climate Risk and Sovereign Credit Ratings

This study will examine climate risk exposures, environmental awareness and attitudes toward climate risk at the country level. These factors have not been widely explored in previous studies on sovereign credit risk. In the first stage (to be conducted in 2022), we will address two questions: (i) How did exposures to climate risk affect a country’s sovereign rating level and rating change?; and (ii) Was there a structural change in sovereign rating criteria toward more stringent ratings following the signing of the Paris Agreement? In the second stage (to be carried out in 2023+), we will examine the effect of environmental awareness on sovereign rating dynamics, and answer this question: Did environmental awareness and attitude toward climate risk in a country moderate the effects of climate risk exposures on its rating level and rating change? This study should contribute to the debates concerning the regulations on climate change and environmental risk mitigation across countries.

Project Title: Improving self-monitoring feedback on eating behavior

Dietary self-monitoring is a key predictor of success in behvioral weight loss programs. To support greater adherence to self-monitoring and to help individuals interpret their own self-monitoring data to set effective behavioral goals, participants are typically provided with interventionist feedback. Currently, there exists little empirical evidence, however, regarding how dietary self-monitoring feedback should be constructed, how participants interpret feedback, and what impact feedback makes on future eating behaviors. Examining perceptions of various forms of dietary self-monitoring feedback (e.g., graphical vs. written vs. oral feedback) as well as the effect of feedback on future eating behaviors would provide necessary insight to inform future research on the optimal design for self-monitoring feedback.

Project Title: Discrediting Vision: Music and Optical Illusion in Nineteenth-Century Europe

This project concerns how optical illusion contributes to a fresh understanding of Wagner's work. I argue that, whereas artists and scientists in post- Industrial Revolution Europe tested the manipulatable nature of human vision, Wagner found in it a source of inspiration for his critical approach to the relationship between sight and sound. His use of offstage music often appeared under the dramatic pretext of supernatural scenes involving optical illusion. I suspect that this approach derived from his larger musical concerns during his creative process. I will travel to the National Wagner Archive to examine his manuscripts of Der fliegende Holländer. This grant will facilitate my archival work and enable me to work with Professor Anno Mungen, whose 2006 monograph BilderMusik dealt with optical technology in similar repertoire. He will broaden my understanding of optical illusion’s impact on music from the perspective of the traditions of German theatre in this context.

Project Title: Reducing Measurement Reactivity in Physical Activity Research

Measurement reactivity is a source of bias in digital assessment of physical activity (PA), though conditions that contribute to its effects are not well understood. This Short-Term Grant will facilitate a collaboration between Dr. Danielle Arigo, a U.S.-based PA researcher, and Dr. Laura König, a Junior Professor at the University of Bayreuth, to achieve 2 research aims: (1) To produce a manuscript comparing PA measurement reactivity across contexts and identifying predictors of reactivity; (2) To generate the project description for a new grant proposal, focused on testing methods for reducing PA measurement reactivity in distinct contexts. During the proposed visit, Drs. Arigo and König will also hold a workshop on digital assessment of weight-related behaviors such as PA. Thus, the work proposed for this Short-Term Grant will provide training opportunities to researchers at University of Bayreuth and promote a collaboration that will help to improve the accuracy of PA measurement.

Project Title: The Role of Reasons in the Ethics of Health Care Allocation

The aim of the project is to develop a new framework for the investigation of allocation issues in health-care. Any agent who makes a claim on health-care resources must provide reasons that support their claim. I propose that distributive justice in health-care resource allocation is therefore best seen as an attempt to maximize reason-based claims of agents on health-care resources. But ought we to make such priority-setting – often called ‘rationing’ – decisions? I propose that the answer to this query also depends on our account of the relevant reasons. In short, the most promising way to approach this area of applied ethics is to focus on the (normative practical) reasons that are relevant to our inquiry. This is a promising way also because in recent years there has been an upsurge in research on reasons. At the same time, this discussion has not made its way into medical ethics. This projects aims to fill this gap by fusing applied, normative and metaethics.

Project Title: Investigation of recombinant spider silk protein encapsulation to enhance upconversion implant biocompatibility and anti-microbial properties

Upconversion nanoparticles (UCN) are nanotransducer for near-infrared (NIR) to visible light, an important feature to breach the tissue depth penetration limitation of visible light. However, the application of UCN solution directly into tissue, limits its clinical translation. We have fabricated UCN based implants with great flexibility demonstrated in wireless photodynamic therapy (PDT) in mice model brain tumour. In order to enhance further translatability of UCN implant (reduce scarring, anti-inflammatory and anti-microbial) recombinant spider silk technology is being explored to coat the UCN implantable. Recombinant spider silk has been demonstrated to be an ideal material that can reduce scarring, inflammation and has anti-bacterial property. We will examine the suitable surface modification for both UCN implant and spider silk for the coating to happen and the durability of the recombinant spider silk, towards the course of PDT.

Project Title:  Distant Reading Modern Historiography: Three Case Studies

Historiography mirrors the narratives of polities. It evokes imagined spaces, assembles groups of agents, defines codes of conduct, and merges them into historical outlines that are meaningful for the self-concept of political entities. Although the connection between historiography and state/nation building is obvious, it has never been tackled from the perspective of large-scale, algorithm-based corpus analysis similar to the way in which, for example, Franco Moretti has applied “distant reading” to literary studies. During the proposed three-week collaboration in 2021, we plan to work on three test cases: a German/Latin work from the 17th century, textbooks from the 19th century, and a comprehensive list of Catholic historiographers from the early modern Holy Roman Empire. We plan to perform a computer-based analysis of (a) the geographic, (b) the prosopographical, and (c) the conceptual and narrative scope of our three data samples. Interested colleagues will be invited to participate.

Project Title: Determinants of phenological events in African savanna trees

In monsoonal, rain-limited climates the timing of phenological events such as fruit production, leaf deployment and leaf abscission determines not only the carbon exchange dynamics of ecosystems, but also the availability of food for animals. The intensity of seed production also varies greatly in intensity and frequency with uncertainty around controls of these dynamics. By using data that has been collected over seven seasons both inside and outside of a protected area, we intend to identify whether resource levels or environmental signals control synchronised reproduction through a state-space modelling approach that will allow us to model the resource status of plants, as well as interactions between climate and resource levels.

Project Title: Design and processing of novel heterogeneous catalytic nanocomposite fibers based on polymer derived ceramics approach

Lignocellulosic biomass which is an abundant, non-expensive and feasible (due to the non-competitive nature in the food chain) material is an excellent choice of replacement for fossil fuel and has wide application in medicinal chemistry. The development of novel catalytic reaction scheme concepts that mediates the conversion of lignocellulose derived alcohols to aromatic N-heterocycles (hydrogen generation/storage) is a challenge. In order to catalyze the corresponding reaction steps more efficiently and to withstand the strong basic conditions during the synthesis, novel catalysts have to be explored. Hence, the aim of this project is to design of a sustainable reusable heterogeneous catalysts based on transition metals, acknowledging the factors such as cost, selectivity, reusability and activity as well as the conservation of limited noble metal resources.

The purpose of this project is to study travel narratives of Wagner fans that had made the trip or "pilgrimage" to Bayreuth’s Festival from Buenos Aires, Argentina. We will study their travel narratives with the aim of understanding transculturation processes from the constructive dimension of music in social and cultural terms. Following a diachronic point of view –from late nineteen century to first half of twentieth–, this approach will allow the analysis of cultural encounters, also revealing the cultural distance perceptions of travelers and fans as well as the singularities of the male and female gaze.

In fact, recent evidence suggests that what we hear can also significantly affect tasting experiences, whether we realize it or not. Felipe Reinoso-Carvalho, together with fellow colleagues from the University of Bayreuth, intend to further explore, from a scientific perspective, the particular role of sound in the behavior of consumers while experiencing foods/drinks.  Here, they would be looking for to discuss such role from three different perspectives: Innovation and consumer protection, food & health sciences, and/or transcultural processes.

Project Title: Structural features of ion-conducting BaLaInO₄ for electrochemical applications: Effect of acceptor and donor doping

In January 2021, Assistant Professor Maxim Vlasov stayed in Assistant Professor Mirijam Zobel's group of solid state chemistry in order to elucidate the structure of oxygen-ion, proton and lithium-ion conducting oxides, for instance BaLaInO4 featuring the Ruddlesden-Popper structure. For this, Mr. Vlasov and Ms. Zobel employed both powder X-ray diffraction and pair distribution function (PDF) analysis based on high energy X-ray scattering data from the state of the art PDF diffractometer in the Zobel laboratory. The combination of this structural insight into the short-range order complements previously obtained electrochemical performance data to ultimately reveal ion transport mechanisms in these materials. The ion-conducting Ruddlesden-Popper oxides were synthesized at the home institute of Mr. Vlasov, the esteemed Institute of High Temperature Electrochemistry in Ekaterinburg, Russia. This scientific cooperation is an extension of the established series of summer schools named Travelling Seminars in the topical field of nanoscale materials and large scale research facilities.

Project Title: Charge transfer mechanisms in light converting systems from Time-Dependent Density Functional Theory

We aim to investigate light converting mechanisms in both artificial and nature systems. Donor-acceptor materials that can be used in organic solar cells and bacteriochlorophyll complexes from photosynthetic bacteria will be studied using Time Dependent Density Functional Theory. An important aspect of our work is the use of approximations that are capable of correctly treating charge transfer excitations. We combine those with an appropriate treatment of intermolecular interactions and long-range dielectric screening coming from solvation effects. Our long-term aim is to contribute to the development of materials that can efficiently convert light to other useful forms of energy.

Project Title: Organizational Digital Identity: Antecedents and Consequences

Digital technologies and digitization of organizational processes constitute increasingly relevant changes in today’s business environment calling for reconsideration of the bases for the normally accepted conception of identity. The objective of our research project is to develop the concept of organizational digital identity and answer the following questions: How groups within and across organizations develop shared digital identity? What are potential benefits of such shared digital identity? We define organizational digital identity as the collective self-concept(s) of an in-group towards the creation, application, development, and emergence of digital technology built on shared fondness, compassion, and proclivity towards digital technology.

Project Title: “Darker legacies”: Colonialism and “Comparative Law”

This project, which forms part of a larger undertaking I have been pursuing since 2017, seeks to explore the role of “comparative law” as intellectually legitimizing colonialism and even actively partaking in the in the colonial project. The method of comparison that gained currency in the 19^th century is intricately intertwined with contemporaneous discourses on “civilization” and “race“ and instrumental in establishing the “colonial difference”.

Project Title: Preference Rankings and Proportional Representation: Mismatches in Germany, 2005-2017

As with all proportional list systems, the German system is afflicted by a fundamental inconsistency known as the More-Preferred-Less-Seats-Paradox. Although this has been known to be a theoretical possibility for a long time, it has never been demonstrated empirically for Germany. We follow a method previously applied to studies of elections in Denmark (1973–2005) and The Netherlands (1982–1994) that reconstructs these preference rankings from opinion polling data. We use flash polls that contain “thermometer data” on party preferences conducted the week before polling day for the Federal Elections in 2005, 2009, 2013, and 2017. The main finding is that each of the elections has been afflicted by the paradox. Qualitatively, it is arguable that the occurrence of the paradox in 2005 and 2009 is relatively benign. But in 2013 and 2017 the paradox took on a different dimension. Firstly, in 2013 the liberal Freie Demokratische Partei (FDP) actually dropped out of parliament although being preferred over the leftwing party DIE LINKE, which was the so-called Condorcet-loser (or least-preferred party). DIE LINKE was the third largest faction in the Parliament and the official opposition. Then in 2017, the populist rightwing party, Alternative für Deutschland (AFD), received the third largest seat share although, as with DIE LINKE in the previous election, it was the Condorcet-loser and it too has become the official opposition. This suggests that the current system has the potential to distort the representation of voter preferences. We discuss the source of the paradox and the normative implications of these results by placing them in the context of representative and epistemic conceptions of democracy.

Project Title: Optimisation of PLA Reinforced Composites for Enhancing Thermal/Electrical Conductivities and Processability Using Machine Learning Approach

Polylactic acid (PLA) is considered as one of major alternative biodegradable polymers to replace conventional petroleum-based polymers due to its excellent biodegradability, environmental sustainability and biocompatibility. Melt compounding of polymer composites requires sophisticated planning and experimental design to achieve optimal properties, which in the past relies on a statistical design of experiments with less reliability and robustness with a limited number of data. Whereas, artificial intelligence particularly with the aid of machine learning or deep learning models offers an alternative route to the systematic development of advanced composite materials towards Industry 4.0. This project aims to develop appropriate machine learning model to identify optimal processing parameters and material formulations in melt compounding of PLA composites reinforced with boron nitride (BN) and carbon black (CB) with hybrid filler effect to enhance thermal/electrical conductivity and processibility, as well as establish a robust processing-structure-property relationship to produce multifunctional composite materials.

Project Title: Modelling Deposition of Organic Photovoltaic Materials in Electric Fields

Photovoltaic materials are promising candidates for facilitating the transition from fossil fuels to renewable energy sources. Organic photovoltaics (OPV) have properties, such as being flexible and light weight that make them attractive for specialty applications. The efficiency of OPV depends on many factors, and one is the morphology of the material, which can be steered by electric fields.  Here we will do computer simulations of the formation of the films under control of electric fields, with the aim to be able to control the morphology in the production process of OPV in order to improve their efficiency.

Project Title: Antimony Mobility and Speciation in Complex, Redox-Active Mineral System

This project aims to advance our fundamental understanding on the geochemistry of antimony – a critical mineral resource and environmental pollutant of growing concern that plays a growing role in our daily lives. This will be achieved by investigating the interplay between antimony and metal oxides in multi-mineral systems. This project will bring together a combination of advanced analytical tools and techniques to examine antimony –iron and manganese interactions in experimental mixed mineral systems. The expected outcomes will provide novel insights into refined strategies to manipulate coupling between antimony mobility and iron and manganese cycling for improved rehabilitation of degraded landscapes.

Project Title: Energetic optimization of spatial arrangement of fish swimming in formation

Fluid dynamics plays an important role in our understanding of animal locomotion. The topic of this collaboration concerns with fish schooling, which refers to a group of fish swimming in the same direction in a coordinated manner. We are developing an analytical model based on approximation of the far flow field induced by an individual swimmer represented as a circular vortex ring. It will help to assess hydrodynamic advantages of schooling and evaluate potential benefit that swimming in a group can offer to small robotic underwater swimmers.
