It is known, however, that the geometry and topology of space can have significant effects on quantum statistics for particles moving on it. Here, we have undertaken the first step toward realizing the emerging fractional statistics for particles restricted to move on the sphere instead of on the plane. We show that such a model arises naturally in the context of quantum impurity problems. In particular, we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic or fermionic molecules immersed in a quantum many-particle environment can coincide with the anyonic spectrum on the sphere. This paves the way toward the experimental realization of anyons on the sphere using molecular impurities. Furthermore, since a change in the alignment of the molecules corresponds to the exchange of the particles on the sphere, such a realization reveals a novel type of exclusion principle for molecular impurities, which could also be of use as a powerful technique to measure the statistics parameter. Finally, our approach opens up a simple numerical route to investigate the spectra of many anyons on the sphere. Accordingly, we present the spectrum of two anyons on the sphere in the presence of a Dirac monopole field.","lang":"eng"}],"article_processing_charge":"No","pmid":1,"related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"12390"}],"link":[{"relation":"press_release","url":"https://ist.ac.at/en/news/dancing-molecules-and-two-dimensional-particles/","description":"News on IST Homepage"}]},"volume":126,"author":[{"full_name":"Brooks, Morris","id":"B7ECF9FC-AA38-11E9-AC9A-0930E6697425","orcid":"0000-0002-6249-0928","first_name":"Morris","last_name":"Brooks"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail","first_name":"Mikhail","last_name":"Lemeshko"},{"full_name":"Lundholm, D.","first_name":"D.","last_name":"Lundholm"},{"full_name":"Yakaboylu, Enderalp","orcid":"0000-0001-5973-0874","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","last_name":"Yakaboylu","first_name":"Enderalp"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd"},{"citation":{"ama":"Grosser JA, Maes ME, Nickells RW.

The mechanism, prevalence, and speed of apoptosis propagation remain unclear. Additionally, no studies have demonstrated propagation of the pro-apoptotic protein, BAX. To evaluate the role of BAX in intracellular apoptotic propagation, we used high speed live-cell imaging to visualize fluorescently tagged-BAX recruitment to mitochondria in four immortalized cell lines. We show that propagation of mitochondrial BAX recruitment occurs in parallel to cytochrome c and SMAC/Diablo release and is affected by cellular morphology, such that cells with processes are more likely to exhibit propagation. The initiation of propagation events is most prevalent in the distal tips of processes, while the rate of propagation is influenced by the 2-dimensional width of the process. Propagation was rarely observed in the cell soma, which exhibited near synchronous recruitment of BAX. Propagation velocity is not affected by mitochondrial volume in segments of processes, but is negatively affected by mitochondrial density. There was no evidence of a propagating wave of increased levels of intracellular calcium ions. Alternatively, we did observe a uniform increase in superoxide build-up in cellular mitochondria, which was released as a propagating wave simultaneously with the propagating recruitment of BAX to the mitochondrial outer membrane.","lang":"eng"}],"external_id":{"pmid":["33426618"],"isi":["000606722600001"]},"publication_status":"published","page":"132-145","article_processing_charge":"No","title":"Characteristics of intracellular propagation of mitochondrial BAX recruitment during apoptosis","volume":26,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","author":[{"last_name":"Grosser","first_name":"Joshua A.","full_name":"Grosser, Joshua A."},{"full_name":"Maes, Margaret E","id":"3838F452-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9642-1085","first_name":"Margaret E","last_name":"Maes"},{"full_name":"Nickells, Robert W.","last_name":"Nickells","first_name":"Robert W."}],"pmid":1},{"status":"public","day":"19","ec_funded":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"citation":{"ama":"Gulden T, Kamenev A.

The long range nature of the inter-ion interactions comes about due to the dielectric constants mismatch between the water and the surrounding medium, confining the electric filed to stay mostly within the water-filled channel. Statistical mechanics of such Coulomb systems is dominated by entropic effects which may be accurately accounted for by mapping onto an effective quantum mechanics. In presence of multivalent ions the corresponding quantum mechanics appears to be non-Hermitian. In this review we discuss a framework for semiclassical calculations for the effective non-Hermitian Hamiltonians. Non-Hermiticity elevates WKB action integrals from the real line to closed cycles on a complex Riemann surfaces where direct calculations are not attainable. We circumvent this issue by applying tools from algebraic topology, such as the Picard-Fuchs equation. We discuss how its solutions relate to the thermodynamics and correlation functions of multivalent solutions within narrow, water-filled channels.

Firstly, we consider sample covariance matrices XX∗ with X having independent identically distributed (i.i.d.) centred entries. We prove a Central Limit Theorem for differences of linear statistics of XX∗ and its minor after removing the first column of X. Secondly, we consider Wigner-type matrices and prove that the eigenvalue statistics near cusp singularities of the limiting density of states are universal and that they form a Pearcey process. Since the limiting eigenvalue distribution admits only square root (edge) and cubic root (cusp) singularities, this concludes the third and last remaining case of the Wigner-Dyson-Mehta universality conjecture. The main technical ingredients are an optimal local law at the cusp, and the proof of the fast relaxation to equilibrium of the Dyson Brownian motion in the cusp regime.\r\nIn the second part we consider non-Hermitian matrices X with centred i.i.d. entries. We normalise the entries of X to have variance N −1. It is well known that the empirical eigenvalue density converges to the uniform distribution on the unit disk (circular law). In the first project, we prove universality of the local eigenvalue statistics close to the edge of the spectrum. This is the non-Hermitian analogue of the TracyWidom universality at the Hermitian edge. Technically we analyse the evolution of the spectral distribution of X along the Ornstein-Uhlenbeck flow for very long time\r\n(up to t = +∞). In the second project, we consider linear statistics of eigenvalues for macroscopic test functions f in the Sobolev space H2+ϵ and prove their convergence to the projection of the Gaussian Free Field on the unit disk. We prove this result for non-Hermitian matrices with real or complex entries. The main technical ingredients are: (i) local law for products of two resolvents at different spectral parameters, (ii) analysis of correlated Dyson Brownian motions.\r\nIn the third and final part we discuss the mathematically rigorous application of supersymmetric techniques (SUSY ) to give a lower tail estimate of the lowest singular value of X − z, with z ∈ C. More precisely, we use superbosonisation formula to give an integral representation of the resolvent of (X − z)(X − z)∗ which reduces to two and three contour integrals in the complex and real case, respectively. The rigorous analysis of these integrals is quite challenging since simple saddle point analysis cannot be applied (the main contribution comes from a non-trivial manifold). Our result\r\nimproves classical smoothing inequalities in the regime |z| ≈ 1; this result is essential to prove edge universality for i.i.d. non-Hermitian matrices.","lang":"eng"}],"publication_status":"published","page":"380","article_processing_charge":"No","OA_place":"publisher","author":[{"first_name":"Giorgio","last_name":"Cipolloni","full_name":"Cipolloni, Giorgio","orcid":"0000-0002-4901-7992","id":"42198EFA-F248-11E8-B48F-1D18A9856A87"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","ddc":["510"],"has_accepted_license":"1","file":[{"date_created":"2021-01-25T14:19:03Z","content_type":"application/pdf","file_name":"thesis.pdf","creator":"gcipollo","success":1,"file_id":"9043","relation":"main_file","checksum":"5a93658a5f19478372523ee232887e2b","access_level":"open_access","file_size":4127796,"date_updated":"2021-01-25T14:19:03Z"},{"creator":"gcipollo","date_created":"2021-01-25T14:19:10Z","content_type":"application/zip","file_name":"Thesis_files.zip","access_level":"closed","relation":"source_file","checksum":"e8270eddfe6a988e92a53c88d1d19b8c","date_updated":"2021-01-25T14:19:10Z","file_size":12775206,"file_id":"9044"}],"corr_author":"1","doi":"10.15479/AT:ISTA:9022","publication_identifier":{"issn":["2663-337X"]},"year":"2021","date_created":"2021-01-21T18:16:54Z","department":[{"_id":"GradSch"},{"_id":"LaEr"}],"publisher":"Institute of Science and Technology Austria","date_updated":"2026-04-08T06:59:33Z","language":[{"iso":"eng"}],"month":"01","date_published":"2021-01-25T00:00:00Z","oa":1,"file_date_updated":"2021-01-25T14:19:10Z","_id":"9022","acknowledgement":"I gratefully acknowledge the financial support from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 665385 and my advisor’s ERC Advanced Grant No. 338804.","type":"dissertation","oa_version":"Published Version","project":[{"call_identifier":"H2020","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385"},{"_id":"258DCDE6-B435-11E9-9278-68D0E5697425","grant_number":"338804","call_identifier":"FP7","name":"Random matrices, universality and disordered quantum systems"}],"citation":{"apa":"Cipolloni, G.

Particularly, polar vdW crystals, such as hexagonal boron nitride (h-BN), alpha-molybdenum trioxide (α-MoO3) or alpha-vanadium pentoxide (α-V2O5), have received significant attention in nano-optics, since they support phonon polaritons (PhPs)―light coupled to lattice vibrations― with strong electromagnetic confinement and low optical losses. Recently, correlative far- and near-field studies of α-MoO3 have been demonstrated as an effective strategy to accurately extract the permittivity of this material. Here, we use this accurately characterized and low-loss polaritonic material to sense its local dielectric environment, namely silica (SiO2), one of the most widespread substrates in nanotechnology. By studying the propagation of PhPs on α-MoO3 flakes with different thicknesses laying on SiO2 substrates via near-field microscopy (s-SNOM), we extract locally the infrared permittivity of SiO2. Our work reveals PhPs nanoimaging as a versatile method for the quantitative characterization of the local optical properties of dielectric substrates, crucial for understanding and predicting the response of nanomaterials and for the future scalability of integrated nanophotonic devices.

DQPTs are defined by nonanalyticities in the return amplitude and are present in many models. In some cases, DQPTs can be related to equilibrium concepts, such as order parameters, yet their universal description is an open question. In this Letter, we provide first steps toward a classification of DQPTs by using a matrix product state description of unitary dynamics in the thermodynamic limit. This allows us to distinguish the two limiting cases of “precession” and “entanglement” DQPTs, which are illustrated using an analytical description in the quantum Ising model. While precession DQPTs are characterized by a large entanglement gap and are semiclassical in their nature, entanglement DQPTs occur near avoided crossings in the entanglement spectrum and can be distinguished by a complex pattern of nonlocal correlations. We demonstrate the existence of precession and entanglement DQPTs beyond Ising models, discuss observables that can distinguish them, and relate their interplay to complex DQPT phenomenology.","lang":"eng"}],"keyword":["General Physics and Astronomy"],"title":"Entanglement view of dynamical quantum phase transitions"},{"oa":1,"file_date_updated":"2021-02-03T10:37:28Z","language":[{"iso":"eng"}],"month":"02","date_published":"2021-02-01T00:00:00Z","publisher":"Institute of Science and Technology Austria","department":[{"_id":"HeEd"},{"_id":"GradSch"}],"date_updated":"2026-04-08T07:01:30Z","oa_version":"Published Version","type":"dissertation","_id":"9056","citation":{"ieee":"G.

The k-fold cover for some discrete input point set consists of the space where at least k balls of radius r around the input points overlap. Persistence is a notion that captures, in some sense, the topology of the shape underlying the input. While persistence is usually computed for the union of balls, the k-fold cover is of interest as it captures local density,\r\nand thus might approximate the shape of the input better if the input data is noisy. To compute persistence of these k-fold covers, we need a discretization that is provided by higher-order Delaunay mosaics. We present and implement a simple and efficient algorithm for the computation of higher-order Delaunay mosaics, and use it to give experimental results for their combinatorial properties. The algorithm makes use of a new geometric structure, the rhomboid tiling. It contains the higher-order Delaunay mosaics as slices, and by introducing a filtration\r\nfunction on the tiling, we also obtain higher-order α-shapes as slices. These allow us to compute persistence of the multi-covers for varying radius r; the computation for varying k is less straight-foward and involves the rhomboid tiling directly. We apply our algorithms to experimental sphere packings to shed light on their structural properties. Finally, inspired by periodic structures in packings and materials, we propose and implement an algorithm for periodic Delaunay triangulations to be integrated into the Computational Geometry Algorithms Library (CGAL), and discuss the implications on persistence for periodic data sets.","lang":"eng"}],"publication_status":"published","degree_awarded":"PhD","title":"Multi-cover persistence and Delaunay mosaics","supervisor":[{"full_name":"Edelsbrunner, Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9823-6833","last_name":"Edelsbrunner","first_name":"Herbert"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","author":[{"orcid":"0000-0002-8882-5116","id":"464B40D6-F248-11E8-B48F-1D18A9856A87","full_name":"Osang, Georg F","first_name":"Georg F","last_name":"Osang"}],"OA_place":"publisher","related_material":{"record":[{"relation":"part_of_dissertation","id":"187","status":"public"},{"status":"public","relation":"part_of_dissertation","id":"8703"}]},"corr_author":"1","file":[{"file_id":"9063","file_size":13446994,"date_updated":"2021-02-03T10:37:28Z","checksum":"bcf27986147cab0533b6abadd74e7629","relation":"source_file","access_level":"closed","content_type":"application/zip","file_name":"thesis_source.zip","date_created":"2021-02-02T14:09:25Z","creator":"patrickd"},{"date_updated":"2021-02-02T14:09:18Z","file_size":5210329,"checksum":"9cc8af266579a464385bbe2aff6af606","relation":"main_file","access_level":"open_access","file_id":"9064","creator":"patrickd","success":1,"content_type":"application/pdf","file_name":"thesis_pdfA2b.pdf","date_created":"2021-02-02T14:09:18Z"}],"has_accepted_license":"1","ddc":["006","514","516"],"year":"2021","date_created":"2021-02-02T14:11:06Z","doi":"10.15479/AT:ISTA:9056","publication_identifier":{"issn":["2663-337X"]}},{"keyword":["General Neuroscience"],"title":"The logic of developing neocortical circuits in health and disease","external_id":{"isi":["000616763400002"],"pmid":["33431633"]},"publication_status":"published","abstract":[{"lang":"eng","text":"The sensory and cognitive abilities of the mammalian neocortex are underpinned by intricate columnar and laminar circuits formed from an array of diverse neuronal populations. One approach to determining how interactions between these circuit components give rise to complex behavior is to investigate the rules by which cortical circuits are formed and acquire functionality during development. This review summarizes recent research on the development of the neocortex, from genetic determination in neural stem cells through to the dynamic role that specific neuronal populations play in the earliest circuits of neocortex, and how they contribute to emergent function and cognition. While many of these endeavors take advantage of model systems, consideration will also be given to advances in our understanding of activity in nascent human circuits. Such cross-species perspective is imperative when investigating the mechanisms underlying the dysfunction of early neocortical circuits in neurodevelopmental disorders, so that one can identify targets amenable to therapeutic intervention."}],"article_processing_charge":"No","page":"813-822","pmid":1,"volume":41,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","author":[{"last_name":"Hanganu-Opatz","first_name":"Ileana L.","full_name":"Hanganu-Opatz, Ileana L."},{"full_name":"Butt, Simon J.

While it is established that F-actin dynamics regulates signaling at the T cell side of the contact, little is known about the cytoskeletal contribution on the DC side. Here, we show that the DC actin cytoskeleton is decisive for the formation of a multifocal synaptic structure, which correlates with T cell priming efficiency. DC actin at the IS appears in transient foci that are dynamized by the WAVE regulatory complex (WRC). The absence of the WRC in DCs leads to stabilized contacts with T cells, caused by an increase in ICAM1-integrin–mediated cell–cell adhesion. This results in lower numbers of activated and proliferating T cells, demonstrating an important role for DC actin in the regulation of immune synapse functionality.","lang":"eng"}],"article_processing_charge":"No"},{"citation":{"chicago":"Pandey, Rakesh, Yusur Al-Nuaimi, Rajiv Kumar Mishra, Sarah K.

Recent studies have established the involvement of a complex signalling network of interactions between cytokines, immune cells and skin cells called keratinocytes. Keratinocytes form the cells of the outermost layer of the skin (epidermis). Visible plaques in psoriasis are developed due to the fast proliferation and unusual differentiation of keratinocyte cells. Despite that, the exact mechanism of the appearance of these plaques in the cytokine-immune cell network is not clear. A mathematical model embodying interactions between key immune cells believed to be involved in psoriasis, keratinocytes and relevant cytokines has been developed. The complex network formed of these interactions poses several challenges. Here, we choose to study subnetworks of this complex network and initially focus on interactions involving TNFα, IL-23/IL-17, and IL-15. These are chosen based on known evidence of their therapeutic efficacy. In addition, we explore the role of IL-15 in the pathogenesis of psoriasis and its potential as a future drug target for a novel treatment option. We perform steady state analyses for these subnetworks and demonstrate that the interactions between cells, driven by cytokines could cause the emergence of a psoriasis state (hyper-proliferation of keratinocytes) when levels of TNFα, IL-23/IL-17 or IL-15 are increased. The model results explain and support the clinical potentiality of anti-cytokine treatments. Interestingly, our results suggest different dynamic scenarios underpin the pathogenesis of psoriasis, depending upon the dominant cytokines of subnetworks. We observed that the increase in the level of IL-23/IL-17 and IL-15 could lead to psoriasis via a bistable route, whereas an increase in the level of TNFα would lead to a monotonic and gradual disease progression. Further, we demonstrate how this insight, bistability, could be exploited to improve the current therapies and develop novel treatment strategies for psoriasis."}],"pmid":1,"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","author":[{"full_name":"Pandey, Rakesh","last_name":"Pandey","first_name":"Rakesh"},{"first_name":"Yusur","last_name":"Al-Nuaimi","full_name":"Al-Nuaimi, Yusur"},{"first_name":"Rajiv Kumar","last_name":"Mishra","id":"46CB58F2-F248-11E8-B48F-1D18A9856A87","full_name":"Mishra, Rajiv Kumar"},{"first_name":"Sarah K.","last_name":"Spurgeon","full_name":"Spurgeon, Sarah K."},{"full_name":"Goodfellow, Marc","last_name":"Goodfellow","first_name":"Marc"}],"OA_place":"publisher","volume":11},{"day":"01","status":"public","citation":{"short":"G.

Although studying marine evolutionary processes is often challenging, recent technological advances in different fields, from maritime engineering to genomics, are making it increasingly possible to study speciation of marine life forms across diverse ecosystems and taxa. Motivated by recent research in the field, including the 14 contributions in this issue, we highlight and discuss six axes of research that we think will deepen our understanding of speciation in the marine realm: (a) study a broader range of marine environments and organisms; (b) identify the reproductive barriers driving speciation between marine taxa; (c) understand the role of different genomic architectures underlying reproductive isolation; (d) infer the evolutionary history of divergence using model‐based approaches; (e) study patterns of hybridization and introgression between marine taxa; and (f) implement highly interdisciplinary, collaborative research programmes.

They increase survival chances and, due to environmental and ecological challenges, may vary substantially even between closely related taxa. These differences are likely to be especially pronounced in long-lived species like crocodilians. This order is particularly relevant for comparative cognition due to its phylogenetic proximity to birds. Here we compared early life behavioral predispositions in two Alligatoridae species. We exposed American alligator and spectacled caiman hatchlings to three different novel situations: a novel object, a novel environment that was open and a novel environment with a shelter. This was then repeated a week later. During exposure to the novel environments, alligators moved around more and explored a larger range of the arena than the caimans. When exposed to the novel object, the alligators reduced the mean distance to the novel object in the second phase, while the caimans further increased it, indicating diametrically opposite ontogenetic development in behavioral predispositions. Although all crocodilian hatchlings face comparable challenges, e.g., high predation pressure, the effectiveness of parental protection might explain the observed pattern. American alligators are apex predators capable of protecting their offspring against most dangers, whereas adult spectacled caimans are frequently predated themselves. Their distancing behavior might be related to increased predator avoidance and also explain the success of invasive spectacled caimans in the natural habitats of other crocodilians.","lang":"eng"}],"pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"full_name":"Reber, Stephan A.","last_name":"Reber","first_name":"Stephan A."},{"first_name":"Jinook","last_name":"Oh","full_name":"Oh, Jinook","orcid":"0000-0001-7425-2372","id":"403169A4-080F-11EA-9993-BF3F3DDC885E"},{"last_name":"Janisch","first_name":"Judith","full_name":"Janisch, Judith"},{"full_name":"Stevenson, Colin","first_name":"Colin","last_name":"Stevenson"},{"last_name":"Foggett","first_name":"Shaun","full_name":"Foggett, Shaun"},{"full_name":"Wilkinson, Anna","first_name":"Anna","last_name":"Wilkinson"}],"volume":24,"has_accepted_license":"1","ddc":["590"],"file":[{"file_name":"2021_AnimalCognition_Reber.pdf","content_type":"application/pdf","date_created":"2021-02-09T07:40:14Z","creator":"dernst","success":1,"file_id":"9107","date_updated":"2021-02-09T07:40:14Z","file_size":1117991,"relation":"main_file","checksum":"d9dfa0d1de6d684692b041d936dd858e","access_level":"open_access"}],"quality_controlled":"1","doi":"10.1007/s10071-020-01461-5","publication_identifier":{"issn":["1435-9448"],"eissn":["1435-9456"]},"issue":"4","publication":"Animal Cognition","date_created":"2021-02-07T23:01:13Z","year":"2021","date_published":"2021-07-01T00:00:00Z","month":"07","language":[{"iso":"eng"}],"date_updated":"2025-06-12T06:34:03Z","publisher":"Springer Nature","department":[{"_id":"SyCr"}],"isi":1,"file_date_updated":"2021-02-09T07:40:14Z","oa":1,"scopus_import":"1","_id":"9101","intvolume":"        24","oa_version":"Published Version","article_type":"original","type":"journal_article","acknowledgement":"We thank Jamie Gilks and Terry Miles for their support at Crocodiles of the World.

We first give a categorification of the mapper graph and the Reeb graph by interpreting them in terms of cosheaves and stratified covers of the real line R. We then introduce a variant of the classic mapper graph of Singh et al. (in: Eurographics symposium on point-based graphics, 2007), referred to as the enhanced mapper graph, and demonstrate that such a construction approximates the Reeb graph of (X,f) when it is applied to points randomly sampled from a probability density function concentrated on (X,f). Our techniques are based on the interleaving distance of constructible cosheaves and topological estimation via kernel density estimates. Following Munch and Wang (In: 32nd international symposium on computational geometry, volume 51 of Leibniz international proceedings in informatics (LIPIcs), Dagstuhl, Germany, pp 53:1–53:16, 2016), we first show that the mapper graph of (X,f), a constructible R-space (with a fixed open cover), approximates the Reeb graph of the same space. We then construct an isomorphism between the mapper of (X,f) to the mapper of a super-level set of a probability density function concentrated on (X,f). Finally, building on the approach of Bobrowski et al. (Bernoulli 23(1):288–328, 2017b), we show that, with high probability, we can recover the mapper of the super-level set given a sufficiently large sample. Our work is the first to consider the mapper construction using the theory of cosheaves in a probabilistic setting. It is part of an ongoing effort to combine sheaf theory, probability, and statistics, to support topological data analysis with random data."}],"publication_status":"published","external_id":{"arxiv":["1909.03488"]},"title":"Probabilistic convergence and stability of random mapper graphs"},{"citation":{"ieee":"Z.

However, issues with safety, storage, and transport of molecular hydrogen impede its realization. Alcohols as liquid H2 carriers could be enablers, but state-of-the-art reforming is difficult, requiring high temperatures >200 °C and pressures >25 bar, and the resulting H2 is carbonized beyond tolerance levels for direct use in fuel cells. Here, we demonstrate ambient temperature and pressure alcohol reforming in a fuel cell (ARFC) with a simultaneous electrical power output. The alcohol is oxidized at the alkaline anode, where the resulting CO2 is sequestrated as carbonate. Carbon-free H2 is liberated at the acidic cathode. The neutralization energy between the alkaline anode and the acidic cathode drives the process, particularly the unusually high entropy gain (1.27-fold ΔH). The significantly positive temperature coefficient of the resulting electromotive force allows us to harvest a large fraction of the output energy from the surrounding, achieving a thermodynamic efficiency as high as 2.27. MoS2 as the cathode catalyst allows alcohol reforming even under open-air conditions, a challenge that state-of-the-art alcohol reforming failed to overcome. We further show reforming of a wide range of alcohols. The ARFC offers an unprecedented route toward hydrogen economy as CO2 is simultaneously captured and pure H2 produced at mild conditions."}],"article_processing_charge":"No","page":"3104-3111","title":"Ambient condition alcohol reforming to hydrogen with electricity output","volume":9,"author":[{"full_name":"Manzoor Bhat, Zahid Manzoor","last_name":"Manzoor Bhat","first_name":"Zahid Manzoor"},{"first_name":"Ravikumar","last_name":"Thimmappa","full_name":"Thimmappa, Ravikumar"},{"full_name":"Dargily, Neethu Christudas ","last_name":"Dargily","first_name":"Neethu Christudas "},{"full_name":"Raafik, Abdul ","last_name":"Raafik","first_name":"Abdul "},{"first_name":"Alagar Raja ","last_name":"Kottaichamy","full_name":"Kottaichamy, Alagar Raja "},{"last_name":"Devendrachari","first_name":"Mruthyunjayachari Chattanahalli ","full_name":"Devendrachari, Mruthyunjayachari Chattanahalli "},{"last_name":"Itagi","first_name":"Mahesh","full_name":"Itagi, Mahesh"},{"last_name":" Makri Nimbegondi Kotresh","first_name":"Harish","full_name":" Makri Nimbegondi Kotresh, Harish"},{"orcid":"0000-0003-2902-5319","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","full_name":"Freunberger, Stefan Alexander","last_name":"Freunberger","first_name":"Stefan Alexander"},{"full_name":"Ottakam Thotiyl, Musthafa ","first_name":"Musthafa ","last_name":"Ottakam Thotiyl"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8"}]
