bulklike joints by gas actuated bonding

in this project i will develop a novel concept and new understanding of metal joining through use of chemical gases in this concept chemical vapour transport cvt technology is unconventionally used to induce a transient liquid phase that could form joints with greatly enhanced mechanical and anticorrosion properties in metal joining a continuous metallic phase must bridge two parts but current bridging phases are weaker and more prone to corrosion than the materials from which the components are made this shortens the lifespan in harsh environments and new avenues need to be explored my preliminary data show that it is possible to1 induce a transient liquid phase by2 exposing metal surfaces to melting point depression element mpd precursors gases using3 chemical vapour transport technologythe concept will result in joints made from the bulk material itself hence both joint and bulk obtains the same surface oxide and microstructure leading to best possible corrosion resistance and strengthin this project insitu characterisation will be used to improve our understanding of chemical vapour technology for processing metals and their oxides benefiting from this knowledge and the production of small components for testing fundamental properties and evaluating performance i will discover the mechanisms in and create models for cvt alloying as well as identify the properties of the novel joints to ensure a wide application of research results i will investigate the joints in corrosive settings targeting the demanding environments found in solar thermal energy storage solid oxide fuel cells and fossil free steel production this novel joining concept could also revolutionise the manufacturing of small complex and highperforming equipment as difficulttojoin alloys could thus be used in difficulttomanufacture components such components are found in turbine engines medical equipment and sensor technology
brothers in arms provenancing metal war gear from the first viking raid to the east

in the period around 750 ce a fleet of viking war ships set sail across the baltic they were ambushed and part of the war party was slain their remains have been found in the form of two ship burials with 40 male warriors buried on the island of saaremaa in modern day estonia four of them we now know to be brothers dubbed the first vikings the fallen warriors and their ships represent the first viking raid the time capsule of 40 warriors accompanied by a wealth of war gear in the form of weaponry and decorative adournments represents a unique and unparalleled opportunity for material culture studies in medieval archaeologymetra is a pioneering research project aimed at equipping early researcher ragnar saage with the advanced analytical skills necessary to investigate and establish the origins of both the iron weapons and the copperalloy decorative elements of the war band this will be achieved using state of the art metal provenancing methods in archaeological science the material investigation aims to complement results from previous research on the burial from strontium isotopes and adna analysis the project will not only shed light on organisation and ingroup identity of a single war band ie issued war gear vs individual armament but it presents an unprecedented opportunity to examine and interrogate material culture armaments across a single family four brothers in arms and their relative can commonalities andor differences in weapon and decoration origins nuance our understanding of the makeup of the viking war band do the four brothers and their relative share weapons from the same smith or do their war goods paint a more complex picture of mobility of norse warriors and their attainment of weapons and adournments in a martial society the results may reshape our understanding of the earliest viking raids as well as improve our understanding on the logistics and organisation of such an event
no time for cosmology decoding dynamics from static cosmological correlations

the beginnings of the universe are encoded in the statistical properties of primordial perturbations imprinted at the hot big bang our understanding of primordial cosmology comes from measurements of these imprinted spatial correlations they form a static pattern and its apparent lack of causality is elegantly explained by an earlier period of time evolution this time evolution from very primordial eras of the universe can not be observed directly for conceptual and practical purposes a reformulation of cosmological perturbation theory in which time is emergent is of fundamental importance we hypothesize that there is an intrinsic description of primordial fluctuations that only uses their statistical properties and in which time emerges our approach has three steps first we propose a systematic development of the theory of boundary differential equations for cosmological correlation functions and the development of new kinematical variables for cosmological correlators with these tools in hand we will calculate a large set of theoretical data cosmological correlations of many different particles coming from a variety of early universe scenarios with this data in hand we will search for new principles from which time evolution emerges from the static distribution of cosmological perturbations having a reformulation of cosmological evolution with emergent time a glimpse into the possible beginning of our universe might become accessible as well as its imprint in cosmological correlations
towards a mechanistic account of maintenance goals

people need to invest tremendous effort and motivational resources to ensure that all the valuable things they have will be maintained on both an individual level eg family households health and a societal level eg public infrastructures the natural environment nevertheless little is known about peoples motivation to routinely maintain nurture and care for what they have psychological theory on motivation has focused on approach eg starting a new relationship and avoidance goals eg avoiding separation and left maintenance goals understudied addressing this gap in the literature the current project introduces and tests a first general model of goaldirected maintenance instead of increasing gains or avoiding negative outcomes maintenance goals are used to stabilize positive current states when maintaining ones existing relationship for instance people are not only avoiding separation they are engaged in a set of acts that stabilizes their relationship in a manner that keeps acute threats like separation at bay in a similar manner environmentalism is not only the aspiration to slow down global warming an avoidance goal but also and perhaps more importantly the aspiration that humanity will learn to maintain a stable relationship with the biological world the proposed empirical research will combine lab studies using implicit behavioral measures with experience sampling methods esm the results of this research will lay the foundation for the study of maintenance goals as distinct from approach and avoidance goals shedding light on processes involved in the most pressing sociopolitical issues of our time

material realizable energy transformation navigating the material bottlenecks of a carbonneutral energy system

the urgent need for a global energy transformation requires major and rapid shifts in energy technologies accompanied by changes in material demand and supply which can potentially result in material bottlenecks despite great interest from policy and research current approaches fail to account for key drivers of material bottlenecks such as i new material demands of specific energy technologies eg iridium for electrolysis ii phasedout material supply eg gypsum from fossil power plants iii competing material demand beyond the energy system eg iridium for smartphones and iv limits in material availability and disposability eg recyclability carbonneutral waste handling resulting in an underestimation of bottlenecks while even more importantly integrated mitigation strategies are not investigated at allmaterialize will generate this urgently needed new holistic understanding about how these drivers can affect the global energy transformation and which mitigation strategies are best suited to pave the way towards a material realizable energy transformation the key novelty of materialize will be to transform elements of the yet disparate fields of energy and material system modelling at unprecedented levels of detail into one innovative interdisciplinary scalable nested and prospective model framework materialize aims to conduct boundarypushing research on the global scale of the whole energy system with 3 objectives i unveil potential material bottlenecks ii identify alternatives navigating these and iii assess the impacts of alternatives on the energy and material systems the deeply advanced understanding of the energymaterial nexus will produce timely insights about most robust transformation pathways which will ultimately open up new frontiers to develop new alternatives and navigation strategies and to explore spatiallyexplicit economic and political implications of a material realizable energy transformation
indigenous women nonhuman world and gender comparing the amazon and siberia

ecofemindi investigates the relations between women and nonhuman world importance of traditional ecological knowledge that women possess in indigenous societies and how this knowledge affects the role of women their status and prestige in the household and the society they live in after decades of discussions about natureculture dichotomy and the dominant role of humans on nature and other nonhuman persons today ecofeminists agree that there is also a parellel between the domination of nature and exploitation of women meanwhile in the middle of environmental conflicts political ontology discuss the need for pluriverse as a possibility instead of dualism of human and animals in western world taking indigenous ideas about their geography that involves nonhumans and master spirits more seriously siberia and amazon regions often host the base for theoretical discussions about animism and nonhuman persons in literature however the gender perspective of these ontologies is hardly mentioned and this caused the humanenvironment relations being described rarely through the lens of critical feminist anthropology ecofemindi aims to go beyond the literature that depict women only as victims of environmental degradation and asks if in societies where the separation of nature from the human world is not that strict such as some indigenous societies does this automatically assign women who are associated with nature to a higher status and secondly do women have a different ontological perception about nonhuman world beyond their subsistence roles ecofemindis design is grounded in empirical and interdisciplinary research crosscutting the fields of environmental anthropology and gender to understand the dynamics of relations between women and nonhuman world in order to answer theresearch questions the project will use qualitative research methods of social anthropology in two indigenous communities in amazons and siberia with a participatory methodology
unravelling high co2induced changes in stomatal development

stomata are epidermal valves responsible for gas exchange in plant aerial tissues their number varies according to different environmental conditions such as co2 concentration high co2 levels negatively regulate stomatal development but how such a repression works is poorly understood in arabidopsis thaliana stomatal precursor cells develop asynchronously throughout leaf epidermis undergoing a first asymmetric entry division that generates a small meristemoid and a larger stomatal lineage ground cell slgc meristemoids can go through up to three asymmetric amplifying divisions before forming mature stomata while slgcs can either undergo asymmetric spacing division or differentiate into pavement cells how each of the three meristemoid division types are affected by co2 is still unknown moreover stomata form with the underlying mesophyll layer in a coordinated way both tissues are involved in co2 sensing and high co2 levels can affect their development what are the factors regulating stomatal development modulation and whether or not an interlayer coordination is required upon high co2 conditions has remained unexplored the proposed project aims to unravel co2induced developmental response in leaf understanding 1 how stomatal asymmetric divisions are affected by co2 2 what are the layerspecific regulators 3 the mechanisms of developmental response spatiotemporal lineage tracing tissuespecific transcriptomics and creation of selected mutant lines will be employed to elucidate how co2 modulates leaf developmental program to reach the proposed goals i will be supervised in advanced confocal microscopy bioinformatic analysis oral and written communication of the research and developing of transferable skills my previous experience as developmental biologist and with transcriptomic analysis together with teaching and tutoring skills acquired will help accomplishing the project goals
