In particular, we take the point of view of modern coding theory and discuss how recent advances in coding for symmetric channels help provide more efficient solutions for the asymmetric case. We consider, in more detail, three basic coding paradigms. The first one is Gallager's scheme that consists of concatenating a linear code with a non-linear mapping so that the input distribution can be appropriately shaped. We explicitly show that both polar codes and spatially coupled codes can be employed in this scenario. Furthermore, we derive a scaling law between the gap to capacity, the cardinality of the input and output alphabets, and the required size of the mapper. The second one is an integrated scheme in which the code is used both for source coding, in order to create codewords distributed according to the capacity-achieving input distribution, and for channel coding, in order to provide error protection. Such a technique has been recently introduced by Honda and Yamamoto in the context of polar codes, and we show how to apply it also to the design of sparse graph codes. The third paradigm is based on an idea of Böcherer and Mathar, and separates the two tasks of source coding and channel coding by a chaining construction that binds together several codewords. We present conditions for the source code and the channel code, and we describe how to combine any source code with any channel code that fulfill those conditions, in order to provide capacity-achieving schemes for asymmetric channels. In particular, we show that polar codes, spatially coupled codes, and homophonic codes are suitable as basic building blocks of the proposed coding strategy. Rather than focusing on the exact details of the schemes, the purpose of this tutorial is to present different coding techniques that can then be implemented with many variants. There is no absolute winner and, in order to understand the most suitable technique for a specific application scenario, we provide a detailed comparison that takes into account several performance metrics."}],"date_created":"2019-07-24T12:38:49Z","external_id":{"arxiv":["1406.7373"]},"author":[{"full_name":"Mondelli, Marco","id":"27EB676C-8706-11E9-9510-7717E6697425","orcid":"0000-0002-3242-7020","last_name":"Mondelli","first_name":"Marco"},{"last_name":"Hassani","first_name":"Hamed","full_name":"Hassani, Hamed"},{"full_name":"Urbanke, Rudiger ","first_name":"Rudiger ","last_name":"Urbanke"}],"title":"How to achieve the capacity of asymmetric channels","date_published":"2018-05-01T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publication":"IEEE Transactions on Information Theory"},{"publication_identifier":{"isbn":["9781538647271"]},"status":"public","publisher":"IEEE","citation":{"ista":"Doan N, Hashemi SA, Mondelli M, Gross WJ. 2018.

The belief propagation (BP) decoder allows for parallel decoding of polar codes, making it suitable for high throughput applications. However, the error-correction performance of polar codes under BP decoding is far from the requirements of 5G. It has been shown that the error-correction performance of BP can be improved if the decoding is performed on multiple permuted factor graphs of polar codes. However, a different BP decoding scheduling is required for each factor graph permutation which results in the design of a different decoder for each permutation. Moreover, the selection of the different factor graph permutations is at random, which prevents the decoder to achieve a desirable error correction performance with a small number of permutations. In this paper, we first show that the permutations on the factor graph can be mapped into suitable permutations on the codeword positions. As a result, we can make use of a single decoder for all the permutations. In addition, we introduce a method to construct a set of predetermined permutations which can provide the correct codeword if the decoding fails on the original permutation. We show that for the 5G polar code of length 1024, the error-correction performance of the proposed decoder is more than 0.25 dB better than that of the BP decoder with the same number of random permutations at the frame error rate of 10 -4 ."}],"month":"12","date_created":"2019-07-30T06:43:15Z","external_id":{"arxiv":["1806.11195"]},"title":"On the decoding of polar codes on permuted factor graphs","author":[{"first_name":"Nghia","last_name":"Doan","full_name":"Doan, Nghia"},{"full_name":"Hashemi, Seyyed Ali","last_name":"Hashemi","first_name":"Seyyed Ali"},{"last_name":"Mondelli","first_name":"Marco","orcid":"0000-0002-3242-7020","id":"27EB676C-8706-11E9-9510-7717E6697425","full_name":"Mondelli, Marco"},{"last_name":"Gross","first_name":"Warren J.","full_name":"Gross, Warren J."}],"date_published":"2018-12-01T00:00:00Z","doi":"10.1109/glocom.2018.8647308","conference":{"start_date":"2018-12-09","name":"GLOBECOM: Global Communications Conference","location":"Abu Dhabi, United Arab Emirates","end_date":"2018-12-13"},"year":"2018","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"extern":"1","publication_status":"published","publication":"2018 IEEE Global Communications Conference ","language":[{"iso":"eng"}]},{"scopus_import":"1","intvolume":"       171","department":[{"_id":"LaEr"}],"day":"14","_id":"690","oa_version":"Preprint","article_processing_charge":"No","quality_controlled":"1","citation":{"apa":"Lee, J., &#38; Schnelli, K.

Social animals could potentially further reduce epidemic risk by altering their social networks in the presence of pathogens, yet there is currently no evidence for such pathogen-triggered responses. We tested this hypothesis experimentally in the ant Lasius niger using a combination of automated tracking, controlled pathogen exposure, transmission quantification, and temporally explicit simulations. Pathogen exposure induced behavioral changes in both exposed ants and their nestmates, which helped contain the disease by reinforcing key transmission-inhibitory properties of the colony's contact network. This suggests that social network plasticity in response to pathogens is an effective strategy for mitigating the effects of disease in social groups."}],"project":[{"call_identifier":"FP7","grant_number":"243071","name":"Social Vaccination in Ant Colonies: from Individual Mechanisms to Society Effects","_id":"25DC711C-B435-11E9-9278-68D0E5697425"}],"external_id":{"isi":["000451124500041"]},"date_created":"2018-12-11T11:44:07Z","author":[{"full_name":"Stroeymeyt, Nathalie","first_name":"Nathalie","last_name":"Stroeymeyt"},{"full_name":"Grasse, Anna V","id":"406F989C-F248-11E8-B48F-1D18A9856A87","first_name":"Anna V","last_name":"Grasse"},{"last_name":"Crespi","first_name":"Alessandro","full_name":"Crespi, Alessandro"},{"full_name":"Mersch, Danielle","last_name":"Mersch","first_name":"Danielle"},{"first_name":"Sylvia","last_name":"Cremer","orcid":"0000-0002-2193-3868","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","full_name":"Cremer, Sylvia"},{"first_name":"Laurent","last_name":"Keller","full_name":"Keller, Laurent"}],"title":"Social network plasticity decreases disease transmission in a eusocial insect","date_published":"2018-11-23T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publication":"Science","publist_id":"8049","publisher":"AAAS","quality_controlled":"1","citation":{"apa":"Stroeymeyt, N., Grasse, A.

In order to understand precise functions of pre- or postsynaptic dopamine receptors (DRs), the development of protocols to differentiate pre- and postsynaptic DRs is essential. So far, most studies on determination and quantification of DRs did not discriminate between subsynaptic localization. Therefore, the aim of the study was to generate a robust workflow for the localization of DRs. This work provides the basis for future work on hippocampal DRs, in light that DRs may have different functions at pre- or postsynaptic sites. Synaptosomes from rat hippocampi isolated by a sucrose gradient protocol were prepared for super-resolution direct stochastic optical reconstruction microscopy (dSTORM) using Bassoon as a presynaptic zone and Homer1 as postsynaptic density marker. Direct labeling of primary validated antibodies against dopamine receptors D1 (D1R) and D2 (D2R) with Alexa Fluor 594 enabled unequivocal assignment of D1R and D2R to both, pre- and postsynaptic sites. D1R immunoreactivity clusters were observed within the presynaptic active zone as well as at perisynaptic sites at the edge of the presynaptic active zone. The results may be useful for the interpretation of previous studies and the design of future work on DRs in the hippocampus. Moreover, the reduction of the complexity of brain tissue by the use of synaptosomal preparations and dSTORM technology may represent a useful tool for synaptic localization of brain proteins.","lang":"eng"}],"publication_status":"published","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","publication":"Molecular Neurobiology","date_published":"2018-06-01T00:00:00Z","volume":55,"status":"public","type":"journal_article","month":"06","isi":1,"year":"2018","language":[{"iso":"eng"}],"page":"4857 – 4869","doi":"10.1007/s12035-017-0688-y","issue":"6"},{"type":"journal_article","status":"public","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"volume":98,"doi":"10.1103/physrevb.98.205110","issue":"20","language":[{"iso":"eng"}],"extern":"1","oa":1,"year":"2018","arxiv":1,"month":"11","article_processing_charge":"No","oa_version":"Preprint","_id":"7058","day":"05","intvolume":"        98","article_type":"original","publisher":"APS","quality_controlled":"1","citation":{"mla":"Modic, Kimberly A., et al. “Chiral Spin Order in Some Purported Kitaev Spin-Liquid Compounds.” <i>Physical Review B</i>, vol. 98, no. 20, 205110, APS, 2018, doi:<a href=\"https://doi.org/10.1103/physrevb.98.205110\">10.1103/physrevb.98.205110</a>.","short":"K.A.

We show that the magnetotropic coefficient can be quantitatively determined from a shift in the resonant frequency of a commercially available atomic force microscopy cantilever under magnetic field. This detection method enables part per 100 million sensitivity and the ability to measure magnetic anisotropy in nanogram-scale samples, as demonstrated on the Weyl semimetal NbP.

A key difficulty has been that real materials also contain non-Weyl quasiparticles, and disentangling the experimental signatures has proven challenging. Here we use magnetic fields up to 95 T to drive the Weyl semimetal TaAs far into its quantum limit, where only the purely chiral 0th Landau levels of the Weyl fermions are occupied. We find the electrical resistivity to be nearly independent of magnetic field up to 50 T: unusual for conventional metals but consistent with the chiral anomaly for Weyl fermions. Above 50 T we observe a two-order-of-magnitude increase in resistivity, indicating that a gap opens in the chiral Landau levels. Above 80 T we observe strong ultrasonic attenuation below 2 K, suggesting a mesoscopically textured state of matter. These results point the way to inducing new correlated states of matter in the quantum limit of Weyl semimetals."}],"date_created":"2019-11-19T13:10:33Z","author":[{"full_name":"Ramshaw, B.

The structure consists of Sr2Pt3As layers alternating with Pt-only corrugated grids. Ab initio calculations predict a metallic character with a dominant role of the Pt d electrons. The electrical resistivity (ρ) and Seebeck coefficient confirm the metallic character, but surprisingly, ρ showed a near-flat temperature dependence. This observation fits the description of the Mooij correlation for electrical resistivity in disordered metals, originally developed for statistically distributed point defects. The discussed material has a long-range crystallographic order, but the high concentration of Pt vacancies, incommensurately ordered, strongly influences the electronic conduction properties. This result extends the range of validity of the Mooij correlation to long-range ordered incommensurately modulated vacancies. Motivated by the layered structure, the resistivity anisotropy was measured in a focused-ion-beam micro-fabricated well oriented single crystal. A low resistivity anisotropy indicates that the layers are electrically coupled and conduction channels along different directions are intermixed."}],"article_type":"original","intvolume":"         5","day":"01","article_processing_charge":"No","oa_version":"Published Version","_id":"7063","quality_controlled":"1","citation":{"chicago":"Martino, Edoardo, Alla Arakcheeva, Gabriel Autès, Andrea Pisoni, Maja D.

In particular, there has been intensive research on reducing the communication cost of training when using multiple computational devices, through reducing the precision of the underlying data representation. Naturally, such methods induce system trade-offs—lowering communication precision could de-crease communication overheads and improve scalability; but, on the other hand, it can also reduce the accuracy of training. In this paper, we study this trade-off space, and ask:Can low-precision communication consistently improve the end-to-end performance of training modern neural networks, with no accuracy loss?From the performance point of view, the answer to this question may appear deceptively easy: compressing communication through low precision should help when the ratio between communication and computation is high. However, this answer is less straightforward when we try to generalize this principle across various neural network architectures (e.g., AlexNet vs. ResNet),number of GPUs (e.g., 2 vs. 8 GPUs), machine configurations(e.g., EC2 instances vs. NVIDIA DGX-1), communication primitives (e.g., MPI vs. NCCL), and even different GPU architectures(e.g., Kepler vs. Pascal). Currently, it is not clear how a realistic realization of all these factors maps to the speed up provided by low-precision communication. In this paper, we conduct an empirical study to answer this question and report the insights."}],"date_created":"2019-11-26T14:19:11Z","title":"Synchronous multi-GPU training for deep learning with low-precision communications: An empirical study","author":[{"first_name":"Demjan","last_name":"Grubic","full_name":"Grubic, Demjan"},{"last_name":"Tam","first_name":"Leo","full_name":"Tam, Leo"},{"id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","full_name":"Alistarh, Dan-Adrian","first_name":"Dan-Adrian","last_name":"Alistarh","orcid":"0000-0003-3650-940X"},{"last_name":"Zhang","first_name":"Ce","full_name":"Zhang, Ce"}],"type":"conference","publication_identifier":{"issn":["2367-2005"],"isbn":["9783893180783"]},"status":"public","doi":"10.5441/002/EDBT.2018.14","has_accepted_license":"1","conference":{"start_date":"2018-03-26","end_date":"2018-03-29","location":"Vienna, Austria","name":"EDBT: Conference on Extending Database Technology"},"page":"145-156","year":"2018","oa":1,"file":[{"content_type":"application/pdf","checksum":"ec979b56abc71016d6e6adfdadbb4afe","file_size":1603204,"file_name":"2018_OpenProceedings_Grubic.pdf","date_updated":"2020-07-14T12:47:49Z","relation":"main_file","date_created":"2019-11-26T14:23:04Z","creator":"dernst","access_level":"open_access","file_id":"7118"}],"language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"month":"03"},{"article_processing_charge":"No","oa_version":"Preprint","_id":"7123","day":"30","department":[{"_id":"DaAl"}],"scopus_import":"1","publisher":"ACM","citation":{"ista":"Alistarh D-A, Aspnes J, Gelashvili R. 2018.

Inspired by recent developments in DNA programming, an extensive series of papers, across different communities, has examined the computability and complexity characteristics of this model. Majority, or consensus, is a central task in this model, in which agents need to collectively reach a decision as to which one of two states A or B had a higher initial count. Two metrics are important: the time that a protocol requires to stabilize to an output decision, and the state space size that each agent requires to do so. It is known that majority requires Ω(log log n) states per agent to allow for fast (poly-logarithmic time) stabilization, and that O(log2 n) states are sufficient. Thus, there is an exponential gap between the space upper and lower bounds for this problem. This paper addresses this question.\r\n\r\nOn the negative side, we provide a new lower bound of Ω(log n) states for any protocol which stabilizes in O(n1–c) expected time, for any constant c > 0. This result is conditional on monotonicity and output assumptions, satisfied by all known protocols. Technically, it represents a departure from previous lower bounds, in that it does not rely on the existence of dense configurations. Instead, we introduce a new generalized surgery technique to prove the existence of incorrect executions for any algorithm which would contradict the lower bound. Subsequently, our lower bound also applies to general initial configurations, including ones with a leader. On the positive side, we give a new algorithm for majority which uses O(log n) states, and stabilizes in O(log2 n) expected time. Central to the algorithm is a new leaderless phase clock technique, which allows agents to synchronize in phases of Θ(n log n) consecutive interactions using O(log n) states per agent, exploiting a new connection between population protocols and power-of-two-choices load balancing mechanisms. We also employ our phase clock to build a leader election algorithm with a state space of size O(log n), which stabilizes in O(log2 n) expected time.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1704.04947"}],"date_updated":"2024-10-21T06:02:41Z","author":[{"first_name":"Dan-Adrian","last_name":"Alistarh","orcid":"0000-0003-3650-940X","full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Aspnes, James","last_name":"Aspnes","first_name":"James"},{"full_name":"Gelashvili, Rati","last_name":"Gelashvili","first_name":"Rati"}],"title":"Space-optimal majority in population protocols","date_created":"2019-11-26T15:10:55Z","external_id":{"isi":["000483921200145"],"arxiv":["1704.04947"]},"type":"conference","status":"public","publication_identifier":{"isbn":["9781611975031"]},"page":"2221-2239","conference":{"start_date":"2018-01-07","location":"New Orleans, LA, United States","end_date":"2018-01-10","name":"SODA: Symposium on Discrete Algorithms"},"doi":"10.1137/1.9781611975031.144","language":[{"iso":"eng"}],"oa":1,"year":"2018","arxiv":1,"isi":1,"month":"01"},{"file":[{"access_level":"open_access","creator":"rcubero","file_id":"7127","file_size":1366813,"checksum":"d642b7b661e1d5066b62e6ea9986b917","content_type":"application/pdf","date_updated":"2020-07-14T12:47:50Z","file_name":"entropy-20-00755-v2.pdf","date_created":"2019-11-26T22:23:08Z","relation":"main_file"}],"language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"year":"2018","extern":"1","oa":1,"issue":"10","doi":"10.3390/e20100755","has_accepted_license":"1","month":"10","type":"journal_article","keyword":["Minimum Description Length","normalized maximum likelihood","statistical criticality","phase transitions","large deviations"],"volume":20,"status":"public","publication_identifier":{"issn":["1099-4300"]},"publication":"Entropy","file_date_updated":"2020-07-14T12:47:50Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","article_number":"755","date_published":"2018-10-01T00:00:00Z","date_created":"2019-11-26T22:18:05Z","title":"Minimum description length codes are critical","author":[{"last_name":"Cubero","first_name":"Ryan J","orcid":"0000-0003-0002-1867","id":"850B2E12-9CD4-11E9-837F-E719E6697425","full_name":"Cubero, Ryan J"},{"last_name":"Marsili","first_name":"Matteo","full_name":"Marsili, Matteo"},{"last_name":"Roudi","first_name":"Yasser","full_name":"Roudi, Yasser"}],"abstract":[{"lang":"eng","text":"In the Minimum Description Length (MDL) principle, learning from the data is equivalent to an optimal coding problem. We show that the codes that achieve optimal compression in MDL are critical in a very precise sense. First, when they are taken as generative models of samples, they generate samples with broad empirical distributions and with a high value of the relevance, defined as the entropy of the empirical frequencies. These results are derived for different statistical models (Dirichlet model, independent and pairwise dependent spin models, and restricted Boltzmann machines). Second, MDL codes sit precisely at a second order phase transition point where the symmetry between the sampled outcomes is spontaneously broken. The order parameter controlling the phase transition is the coding cost of the samples. The phase transition is a manifestation of the optimality of MDL codes, and it arises because codes that achieve a higher compression do not exist. These results suggest a clear interpretation of the widespread occurrence of statistical criticality as a characterization of samples which are maximally informative on the underlying generative process."}],"date_updated":"2021-01-12T08:11:56Z","intvolume":"        20","article_type":"original","_id":"7126","oa_version":"Published Version","article_processing_charge":"No","day":"01","ddc":["519"],"citation":{"short":"R.J.

Using the metaphor of a fitness landscape, local optima correspond to hills separated by fitness valleys that have to be overcome. We define a class of fitness valleys of tunable difficulty by considering their length, representing the Hamming path between the two optima and their depth, the drop in fitness. For this function class we present a runtime comparison between stochastic search algorithms using different search strategies. The (1+1) EA is a simple and well-studied evolutionary algorithm that has to jump across the valley to a point of higher fitness because it does not accept worsening moves (elitism). In contrast, the Metropolis algorithm and the Strong Selection Weak Mutation (SSWM) algorithm, a famous process in population genetics, are both able to cross the fitness valley by accepting worsening moves. We show that the runtime of the (1+1) EA depends critically on the length of the valley while the runtimes of the non-elitist algorithms depend crucially on the depth of the valley. Moreover, we show that both SSWM and Metropolis can also efficiently optimise a rugged function consisting of consecutive valleys."}],"date_updated":"2025-04-15T08:22:22Z","type":"journal_article","volume":80,"status":"public","pubrep_id":"1014","ec_funded":1,"language":[{"iso":"eng"}],"file":[{"checksum":"7d92f5d7be81e387edeec4f06442791c","file_size":691245,"content_type":"application/pdf","date_updated":"2020-07-14T12:47:54Z","file_name":"IST-2018-1014-v1+1_2018_Paixao_Escape.pdf","relation":"main_file","date_created":"2018-12-12T10:08:14Z","creator":"system","access_level":"open_access","file_id":"4674"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"year":"2018","oa":1,"issue":"5","doi":"10.1007/s00453-017-0369-2","has_accepted_license":"1","page":"1604 - 1633","month":"05","isi":1},{"language":[{"iso":"eng"}],"publication":"ACS Applied Nano Materials","year":"2018","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","extern":"1","doi":"10.1021/acsanm.8b01036","issue":"9","page":"4863-4874","date_published":"2018-09-28T00:00:00Z","date_created":"2020-01-13T21:58:27Z","title":"Quasi-monodisperse transition-metal-doped BaTiO3 (M = Cr, Mn, Fe, Co) colloidal nanocrystals with multiferroic properties","author":[{"id":"D93824F4-D9BA-11E9-BB12-F207E6697425","full_name":"Costanzo, Tommaso","first_name":"Tommaso","last_name":"Costanzo","orcid":"0000-0001-9732-3815"},{"last_name":"McCracken","first_name":"John","full_name":"McCracken, John"},{"first_name":"Aurelian","last_name":"Rotaru","full_name":"Rotaru, Aurelian"},{"first_name":"Gabriel","last_name":"Caruntu","full_name":"Caruntu, Gabriel"}],"month":"09","abstract":[{"lang":"eng","text":"The recent demand of multifunctional materials and devices for advanced applications in energy conversion and data storage resulted into a revival of multiferroics, that is, materials characterized by the coexistence of ferromagnetism and ferroelectricity. Despite intense efforts made in the past decade, single-phase room temperature multiferroics are yet to be discovered/fabricated. Nanostructured ferroic materials could potentially exhibit multiferroism since a high fraction of their atoms/ions are superficial, thereby altering significantly the properties of the bulk phase. Alternately, a magnetic order can be induced into ferroelectric materials upon aliovalent doping with magnetic ions. Here, we report on the synthesis of aggregate-free single-phase transition-metal-doped BaTiO3 quasi-monodisperse cuboidal nanocrystals (NC) which exhibit multiferroic properties at room temperature and can be suitable for applications in data storage. The proposed synthetic route allows the inclusion of a high concentration of magnetic ions such as Mn+ (M = Cr, Mn, Fe, Co) up to a nominal concentration of 4% without the formation of any secondary phase. The size of the nanocrystals was controlled in a wide range from ∼15 up to ∼70 nm by varying the reaction time from 48 to 144 h. The presence of unpaired electrons and their magnetic ordering have been probed by electron paramagnetic resonance spectroscopy (EPR), and a vibrating sample magnetometer (VSM). Likewise, an acentric structure, associated with the existence of a dielectric polarization, was observed by lattice dynamics analysis and piezoresponse force microscopy (PFM). These results show that high-quality titanium-containing perovskite nanocrystals which display multiferroic properties at room temperature can be fabricated via soft solution-based synthetic routes, and the properties of these materials can be modulated by changing the size of the nanocrystals and the concentration of the dopant thereby opening the door to the design and study of single-phase multiferroic materials."}],"date_updated":"2023-02-23T13:02:57Z","intvolume":"         1","article_type":"original","_id":"7271","type":"journal_article","oa_version":"None","article_processing_charge":"No","day":"28","volume":1,"quality_controlled":"1","citation":{"ista":"Costanzo T, McCracken J, Rotaru A, Caruntu G. 2018.

In these cathodes, Li2CO3 decomposes to CO2 when exposed to potentials above 3.8 V vs. Li/Li+. However, O2 evolution, as would be expected according to the decomposition reaction 2 Li2CO3→4 Li++4 e−+2 CO2+O2, is not detected. O atoms are thus unaccounted for, which was previously ascribed to unidentified parasitic reactions. Here, we show that highly reactive singlet oxygen (1O2) forms upon oxidizing Li2CO3 in an aprotic electrolyte and therefore does not evolve as O2. These results have substantial implications for the long‐term cyclability of batteries: they underpin the importance of avoiding 1O2 in metal‐O2 batteries, question the possibility of a reversible metal‐O2/CO2 battery based on a carbonate discharge product, and help explain the interfacial reactivity of transition‐metal cathodes with residual Li2CO3.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publication":"Angewandte Chemie International Edition","file_date_updated":"2020-07-14T12:47:55Z","date_published":"2018-03-15T00:00:00Z","quality_controlled":"1","citation":{"ieee":"N.

The potential of hydrogels, such as those based on perylene bisimides, lies in their chemical, physical, optical, and electronic properties, which are governed by the supramolecular structure of the gel. However, the structural motifs and their precise role for long-range conductivity are yet to be explored. Here, we present a comprehensive structural picture of a perylene bisimide hydrogel, suggesting that its long-range conductivity is limited by charge transfer between electronic backbones. We reveal nanocrystalline ribbon-like structures as the electronic and structural backbone units between which charge transfer is mediated by polar solvent bridges. We exemplify this effect with sensing, where exposure to polar vapor enhances conductivity by 5 orders of magnitude, emphasizing the crucial role of the interplay between structural motif and surrounding medium for the rational design of devices based on nanocrystalline hydrogels.","lang":"eng"}],"date_updated":"2021-01-12T08:12:46Z","file_date_updated":"2020-07-14T12:47:55Z","publication":"ACS Nano","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","date_published":"2018-06-05T00:00:00Z","volume":12,"status":"public","publication_identifier":{"issn":["1936-0851"]},"type":"journal_article","month":"06","file":[{"relation":"main_file","date_created":"2020-06-29T14:56:40Z","date_updated":"2020-07-14T12:47:55Z","file_name":"Manuscript 20092017_subm.pdf","file_size":1333353,"content_type":"application/pdf","checksum":"050f7f0ba5d845c5c71779ef14ad5ef3","file_id":"8052","creator":"sfreunbe","access_level":"open_access"}],"language":[{"iso":"eng"}],"year":"2018","extern":"1","oa":1,"doi":"10.1021/acsnano.8b01689","issue":"6","page":"5800-5806","has_accepted_license":"1"}]
