towards green hydrogen by layered metal halide perovskite heterostructures

green hydrogen is feedstock fuel energy carrier and storage at the same time and one of the important cornerstones to decarbonize industrial and economic sectors on the european continent the proposed action towards green hydrogen by layered metal halide perovskite heterostructures together will deliver a highly tunable material platform by integrating lateral heterostructures in twodimensional layered metal halide perovskites 2dlp to overcome the high exciton binding energy and ultimately enable longdistance charge separation for photocatalytic generation of green hydrogen the structures developed in together will provide a spatially confined directional flow of electrons to the edge of the semiconducting layer in 2dlps where they can be extracted by protons to form hydrogen the unique flexibility of the materials platform architecture will result in a large degree of freedom to tune each step in the photocatalytic cycle to increase the solartofuel conversion efficiency the formation of lateral heterostructures in 2dlps will be achieved through tailored consecutive ion exchange which is a powerful tool to manipulate the composition while maintaining the crystal structure size and shape of the parent object together is a highly interdisciplinary effort that builds on cuttingedge research in material science with chemistry physics and engineering
wrinklemediated catalysis of 2d materials

the global climate and energy crisis demands decisive actions to implement sustainable energy production and utilization processes catalysis has demonstrated its importance down this route by enabling the transformation of abundant recyclable resources such as water and co2 into widely utilized fuels and chemical feedstock customizing catalysts to improve the performance of these processes is one of the main pursuits of catalytic chemistry a class of materials with atomically thin constituents labelled 2d materials 2dm exhibit widely tunable properties of interest for catalytic applications on top of their high surface area extraordinary mechanical properties and great conductivity thermal and electrical they allow a precise control over their electronic properties beyond conventional metals and semiconductors the tunable electronic properties of 2dm can be exploited to a great extent in order to tailor catalytic performance in particular it has been shown that perturbations such as dislocations vacancies edges impurities and functional groups readily modify the density of states in graphene and promote its catalytic properties although mastering and translating these properties into catalytic specific applications is not an easy task the present project will venture into the often overlooked and challenging front of nanoscale engineering of 2dm for catalysis wildcat will employ morphological alterations in 2dm such as wrinkles for the facilitation of catalytic applications by precisely engineering the geometry of these deformations we can reversibly tune selectivity and susceptibility of chemical reactions without inducing any structural defects the catalytic responses will be assessed with advanced insitu nanoscale characterization tools in order to probe the contribution of wrinkle engineering wildcat has the ambition to expand our understanding of reaction engineering and pave the way for selective catalysts ondemand
search for millilenses to discriminate between dark matter models

one of the most compelling mysteries in both cosmology and particle physics is the nature of dark matter dm we propose to investigate this problem using strong gravitational lensing of active galaxies on the key but poorlyexplored milliarcsecond scales gravitational lensed images with angular separation on milliarcsecond scales probe gravitational lens systems where the lens is a compact object with mass in the range 106 109 solar masses this mass range is particularly critical for the widely accepted lambdacdm cosmological model which predicts many more dm subhalos ie dm halos on subgalactic scales masses below 1011 solar masses than currently observed the most direct way to explore these small angular scales is through the highresolution of radio very long baseline interferometry vlbi we propose to use vlbi data on a complete and large sample of active galaxies 5000 sources to search for gravitational lens systems on milliarcsecond scales given that no gravitational lenses on milliarsecond scales have yet been found if any of the gravitational lens candidates that this search will produce is indeed confirmed as a true gravitational lens system this would be a first and a major discovery a null result instead will allow us to infer a new constraint on the abundance of compact objects in the mass range of interest with over an order of magnitude better precision than in previous studies and tighter than the number of 106 109 solar masses subhalos predicted by lambdacdm such a constraint could help discriminate between dm models that predict different numbers of subhalos in this mass range it could also help to constrain a possible contribution of primordial black holes as a dm component

othering the renaissance conceptualizing foreigners slaves and infidels in in early modern political thought ca 15201610

this research proposal studies how 16th century renaissance aristotelian authors theorized otherness and dealt with outcasts in their political works the very idea of political community in early modern political philosophy is based on the view that as stated by aristotle in his politics some categories of people women foreigners infidels slaves children must be excluded from citizenship because they are considered ontologically different and therefore politically unequal this makes some people outcasts of the political community and raises important questions on which grounds are outcasts excluded from citizenship what is their relationship to citizens which type of inequality does the exclusion of outcasts entail are there different forms of inequality at stake in the exclusion of others othren provides the first comprehensive study of how some 16th century aristotelian thinkers theorized three figures of outcasts foreigners slaves and infidels in their political thoughts and how this helped shape their ideas on such different minorities as jews muslims and amerindians the proposal focuses especially on political works that were influenced by political aristotelianism both in the humanist and scholastic traditions these works are assessed against the backgrounds of roman political thought especially cicero and seneca roman law and the teachings of christian anthropology that shaped early modern political thought

limits of structural tractability

the combination of methods from logic and graph theory has been extremely successful in the design of algorithms in complexity theory and other areas of theoretical computer science a success story exemplifying the power of this approach is the recent development in the algorithmic structure theory of sparse graphs in this line of research structural results stemming from robertson and seymours graph minor theory and the more recent sparsity theory of neetil and ossona de mendez were com bined with logical methods in order to obtain a systematic understanding of tractability an example result in this area states that every graph property definable in first order logic can be decided in linear time for all planar graphs culminating a long line of research grohe kreutzer and siebertz gener alized this result to all nowhere dense graph classes those are very general classes of sparse graphs which include the class of planar graphs classes of bounded maximum degree or classes excluding a fixed minor moreover this result completely delimits the tractability frontier for sparse graph classes however many classes are tractable but not sparse the recent twinwidth theory drawing on deep connections between logic and enumerative combinatorics achieves an analogue of the result of grohe et al for all ordered graphs thus algorithmic tractability is now understood in two contexts of sparse graphs and of ordered graphs this project sets out to characterize all tractable graph classes this requires developing a systematic understanding of the logical structure underlying algorithmic tractability the tools i intend to apply and develop originate from graph structure theory and from stability theory one of the most successful areas in logic recently the expected results will be of foundational nature and of interest primarily to theoretical computer scientists graph theorists and logicians
understanding and harnessing natural variation in adaptability

the rise of antimicrobial resistance is an urgent global threat to human health and global healthcare capacities despite ongoing efforts to develop new antimicrobial drugs eventual adaptation is an inevitable corollary of evolution longterm solutions therefore require innovative approaches including 1 learning to predict adaptation and 2 developing platforms to screen strategies against microbial adaptation the capacity of an organism to adapt to new environments also described as adaptability is a heritable trait that varies substantially between even closely related lineages dissecting the genetic basis and mechanisms driving variation in adaptability is the critical first step in achieving these longterm objectivesas an mcsa fellow dr xanita saayman will receive training from dr gianni liti at the institute for research in cancer and ageing ircan and from dr jonas warringer during a secondment to the university of gothenburg throughout natadapt dr saayman will exploit an extensive collection of saccharomyces cerevisiae isolates with unprecedented scales of phenotypic and genotypic diversity bridging interdisciplinary fields eg population genetics phenomics genomics genome engineering natadapt will identify and characterise genetic drivers of adaptability harnessing this knowledge for two applications first natadapt will model adaptation dynamics based on quantifiable genome properties serving as an invaluable resource for predicting the emergence of antimicrobial resistance second natadapt will produce hyperevolver saccharomyces cerevisiae strains such strains can serve as critical platforms with which to screen strategies against microbial adaptation improving the efficacy of current antimicrobial solutions
retelling and repetition towards a literary history of derivation

why are contemporary readers so fascinated by retellings of the iliad or beowulf and why have retellings of premodern ancient and medieval texts not been taken seriously as a literary practice to date in derivate i investigate the striking surge of retellings in contemporary english literature by setting the contemporary texts in a productive dialogue with practices of writing in the middle ages the medieval period offers a perfect point of departure for theorizing retellings as medieval literature was inherently derivative and medieval authors had developed a system for being inventive within a system of derivations taking issue with the privileging of that which is new in literary history i propose a new paradigm for literary history literary history as a history of derivations starting from the premise that retelling is a transhistorical concept the project sheds new light on the processes of reception that find their expression in the current interest in and relevance of premodern material the project triangulates classical reception studies medieval literary studies as well as literary theory especially postmodernist theory and scrutinizes the practice of retelling premodern ancient and medieval texts in contemporary english literature derivate thus develops a theory of retelling based on the intense engagement and critical comparison with medieval practices of retelling in order to map the wider cultural historical and literary contexts and implications of the current trend in retellings of classical and medieval texts audiences canon literary market as a springboard for developing a literary history of derivations
sustainable and high performance membranes via interfacial complexation shipment

membrane technology is a very sustainable approach to separation as it requires much less energy than conventional separation approaches but the sustainable image of membranes becomes substantially tarnished when you realize that nearly all membranes are prepared using large quantities of toxic and unsustainable aprotic solvents nmp dmf etc to secure the future of membrane technology it becomes critical to develop more sustainable approaches to membrane fabrication an aqueous phase separation aps technique has recently been proposed by the pi as a green and sustainable alternative to the currently dominant nonsolvent induced phase separation nips process14 aps utilizes polyelectrolytes such as polysodium 4styrenesulfonate pss polydiallyldimethylammonium chloride pdadmac polyallyl amine hydrochloride pah and polyethyleneimine pei to obtain sustainable polyelectrolyte complex pec membranes in a completely waterbased process the structure and morphology of these aps membranes can easily be controlled to produce excellent separation properties although aps membranes show high solute retentions the water permeability is much lower than nips membranes now utilized for the same application this originates from the fact that the separation is performed by the same material that gives the membrane its mechanical strength and porosity as a result the water permeability is compromised when utilizing dense and mechanically strong membranes but mechanical properties are poor when more swollen materials are used that provide a high water permeability the lower water permeability of the existing aps membranes is now the major obstacle preventing their commercial production and large scale industrial acceptance herein we propose a modification of the aps procedure by employing interfacial complexation ic during the phase inversion step to produce composite membranes that ultimately lead to the required high performances
contextfree model checking for recursive probabilistic programs

iot and embedded systems are powered by increasingly sophisticated software components employing machine learning to create devices that perform activities once exclusively carried out by humans since these activities may involve significant risks and responsibilities ensuring the correctness and safety of involved software components is crucial probabilistic programs pps are often employed in aipowered software particularly to exploit bayesian inference and to model randomized algorithms thus studying verification of pps can enable verification techniques for ensuring safety and correctness of aipowered programs pps are computer programs that besides ordinary programming constructs may contain random choices and variable assignments according to a random distributionthe corpora contextfree model checking for recursive probabilistic programs project aims at developing new techniques for the verification of recursive probabilistic programs one of the most expressive classes of pps recursive pps may contain recursive procedures since procedures are governed by a stack they exhibit a contextfree behavior in execution traces verification of procedural programs has motivated the study of model checking pushdown formalisms the need for specifying properties concerning the stacks contents has led to the introduction of adhoc specification formalisms including temporal logics featuring contextfreeaware modalities such as caret nwtl and potl the latter being introduced by the applicant during his phdthe corpora project will extend the contextfree model checking framework to recursive pps and its research objectives will encompass the theoretical and practical study of model checking thereof the projects expected results include a model checker for contextfree properties of recursive pps which will enable the practical evaluation of the techniques developed in the project
hybrid and interpretable deep neural audio machines

machine listening or ai for sound is defined as the general field of artificial intelligence applied to audio analysis understanding and synthesis by a machine the access to ever increasing supercomputing facilities combined with the availability of huge data repositories although largely unannotated has led to the emergence of a significant trend with pure datadriven machine learning approaches the field has rapidly moved towards endtoend neural approaches which aim to directly solve the machine learning problem for raw acoustic signals but often only loosely taking into account the nature and structure of the processed data the main consequences are that the models are 1 overly complex require massive amounts of data to be trained and extreme computing power to be efficient in terms of task performance and 2 remain largely unexplainable and noninterpretable to overcome these major shortcomings we believe that our prior knowledge about the nature of the processed data their generation process and their perception by humans should be explicitly exploited in neuralbased machine learning frameworks the aim of hiaudio is to build such hybrid deep approaches combining parameterefficient and interpretable signal models musicological and physicsbased models with highly tailored deep neural architectures the research directions pursued in hiaudio will exploit novel deterministic and statistical audio and sound environment models with dedicated neural autoencoders and generative networks and target specific applications including speech and audio scene analysis music information retrieval and sound transformation and synthesis
