Projekt: 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.

Projekt: Excursions to Bayreuth: travel narrative, identifications and transcultural experiences of Wagner fans (Argentina/Germany, 1890-1940)

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.

Forschungsgebiete: Kulturgeschichte; Kulturgeschichte der Musik, Opernstudien, Transkulturationsprozesse; Migrationsstudien; Weltgeschichte.

Projekt: Sonic seasoning: Rethinking tasting experiences through music

Gastronomy and the food industry are aware of the role of most senses in the experience of foods and beverages. In fact, recent evidence suggests that even what we hear can significantly affect tasting experiences, whether we realize it or not.  Felipe Reinoso-Carvalho (U. de los Andes), together with fellow colleagues from U. Bayreuth, intend to explore, from a scientific perspective, the particular role of sound in the behavior of consumers while experiencing foods/drinks.  Here, we would be looking for to discuss such role from three different perspectives: Innovation and consumer protection, food & health sciences, and/or transcultural processes.

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

High-temperature ion conductors based on complex oxides attract big attention due to the possibility of their application in various areas of electrochemistry. Their conductivity properties are highly dependent on the short-range order/disorder of the crystal structure, and thus can be modified by doping one or several sublattices. With this research project, on the example of BaLaInO4, the Ruddlesden-Popper type oxide, we want to perform a thorough structural study by X-ray pair distribution function (PDF) analysis to get the detailed insight into the local structural distortions caused by doping and reveal correlations between structural features and conductivity properties.

Professor Nilufer E. Bharucha 
Direktorin, CoHaB Indian Diaspora Centre, University of Mumbai, India

The aim of Professor Bharucha’s visit is to explore the potential, at Bayreuth, for an institutionalized platform for graduate research on diasporic literature and culture. This school would focus on representations of migration and diaspora, in particular with a view to concepts of the future. It would be situated within UBT’s emerging field Cultural Encounters and Transcultural Processes. In order to initiate conversations on this topic, Professor Bharucha will be a key speaker at a conference on “symbolism of the future” in March 2020 with a lecture on symbols of the future in the literature of the Indian diaspora.

Projekt: 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.

Projekt: 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.

Projekt: “Darker legacies”: Colonialism and “Comparative Law”

Photo Prof Dedek

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 19th century is intricately intertwined with contemporaneous discourses on “civilization” and “race.“ The project focuses, in particular, on the involvement of comparatists in colonial administrative endeavours, e.g. colonial statutes supposed to navigate the perceived gap between the “civilized” laws of the colonizer and the local “customs”. Striking is, again, the omnipresence of “race” as a distinguishing factor in the attempts to regulate social reality in the colonies.

Projekt: 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.

Projekt: Mechanical, Thermal and Electrical Properties of Polylactic Acid (PLA)/Bamboo Charcoal (BC) Multifunctional Bionanocomposites

PLA is a popular biodegradable polymer used in material packaging, biomedical engineering and pharmaceutical devices. The incorporation of nanofillers in polymer nanocomposites has been widely investigated while the study on bamboo charcoal (BC) nanoparticles is still at its infant stage despite their abundant resources, high surface areas, degree of porosity and absorption ability used for pollutant removal and gas purification. This project aims to successfully fabricate PLA/BC bionanocomposites using twin screw extrusion and compression moulding and simultaneously enhanced mechanical, thermal and electrical properties of tailored PLA/BC bionanocomposites as multifunctional materials to deeply understand their good processing-structure-property relationship.

Projekt: 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.

Projekt: 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.

Projekt: 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.
