To the observer it is therefore intriguing when a moving collective exhibits order. Collective motion of flocks of birds, schools of fish or swarms of self-propelled particles or robots have been studied extensively over the past decades but the mechanisms involved in the transition from chaos to order remain unclear. Here, the interactions, that in most systems give rise to chaos, sustain order. In this thesis we investigate mechanisms that preserve, destabilize or lead to the ordered state. We show that endothelial cells migrating in circular confinements transition to a collective rotating state and concomitantly synchronize the frequencies of nucleating actin waves within individual cells. Consequently, the frequency dependent cell migration speed uniformizes across the population. Complementary to the WAVE dependent nucleation of traveling actin waves, we show that in leukocytes the actin polymerization depending on WASp generates pushing forces locally at stationary patches. Next, in pipe flows, we study methods to disrupt the self--sustaining cycle of turbulence and therefore relaminarize the flow. While we find in pulsating flow conditions that turbulence emerges through a helical instability during the decelerating phase. Finally, we show quantitatively in brain slices of mice that wild-type control neurons can compensate the migratory deficits of a genetically modified neuronal sub--population in the developing cortex.

lang: eng text: "Superconductor-semiconductor heterostructures currently capture a significant amount of research interest and they serve as the physical platform in many proposals towards topological quantum computation.\r\nDespite being under extensive investigations, historically using transport techniques, the basic properties of the interface between the superconductor and the semiconductor remain to be understood.\r\n\r\nIn this thesis, two separate studies on the Al-InAs heterostructures are reported with the first focusing on the physics of the material motivated by the emergence of a new phase, the Bogoliubov-Fermi surface. \r\nThe second focuses on a technological application, a gate-tunable Josephson parametric amplifier.\r\n\r\nIn the first study, we investigate the hypothesized unconventional nature of the induced superconductivity at the interface between the Al thin film and the InAs quantum well.\r\nWe embed a two-dimensional Al-InAs hybrid system in a resonant microwave circuit allowing measurements of change in inductance.\r\nThe behaviour of the resonance in a range of temperature and in-plane magnetic field has been studied and compared with the theory of conventional s-wave superconductor and a two-component theory that includes both contribution of the $s$-wave pairing in Al and the intraband $p \\pm ip$ pairing in InAs.\r\nMeasuring the temperature dependence of resonant frequency, no discrepancy is found between data and the conventional theory.\r\nWe observe the breakdown of superconductivity due to an applied magnetic field which contradicts the conventional theory.\r\nIn contrast, the data can be captured quantitatively by fitting to a two-component model.\r\nWe find the evidence of the intraband $p \\pm ip$ pairing in the InAs and the emergence of the Bogoliubov-Fermi surfaces due to magnetic field with the characteristic value $B^* = 0.33~\\mathrm{T}$.\r\nFrom the fits, the sheet resistance of Al, the carrier density and mobility in InAs are determined.\r\nBy systematically studying the anisotropy of the circuit response, we find weak anisotropy for $B < B^*$ and increasingly strong anisotropy for $B > B^*$ resulting in a pronounced two-lobe structure in polar plot of frequency versus field angle.\r\nStrong resemblance between the field dependence of dissipation and superfluid density hints at a hidden signature of the Bogoliubov-Fermi surface that is burried in the dissipation data.\r\n\r\nIn the second study, we realize a parametric amplifier with a Josephson field effect transistor as the active element.\r\nThe device's modest construction consists of a gated SNS weak link embedded at the center of a coplanar waveguide resonator.\r\nBy applying a gate voltage, the resonant frequency is field-effect tunable over a range of 2 GHz.\r\nModelling the JoFET minimally as a parallel RL circuit, the dissipation introduced by the JoFET can be quantitatively related to the gate voltage.\r\nWe observed gate-tunable Kerr nonlinearity qualitatively in line with expectation.\r\nThe JoFET amplifier has 20 dB of gain, 4 MHz of instantaneous bandwidth, and a 1dB compression point of -125.5 dBm when operated at a fixed resonant frequency.\r\nIn general, the signal-to-noise ratio is improved by 5-7 dB when the JoFET amplifier is activated compared.\r\nThe noise of the measurement chain and insertion loss of relevant circuit elements are calibrated to determine the expected and the real noise performance of the JoFET amplifier.\r\nAs a quantification of the noise performance, the measured total input-referred noise of the JoFET amplifier is in good agreement with the estimated expectation which takes device loss into account.\r\nWe found that the noise performance of the device reported in this document approaches one photon of total input-referred added noise which is the quantum limit imposed in nondegenerate parametric amplifier." acknowledged_ssus: -

The main focus is on weak-strong stability properties of some curvature driven interface evolution problems, such as the two-phase Navier–Stokes flow with surface tension and multiphase mean curvature flow, and on the phase-field approximation of the latter. Furthermore, we discuss a variational approach to the study of a class of doubly nonlinear wave equations.\r\nFirst, we consider the two-phase Navier–Stokes flow with surface tension within a bounded domain. The two fluids are immiscible and separated by a sharp interface, which intersects the boundary of the domain at a constant contact angle of ninety degree. We devise a suitable concept of varifolds solutions for the associated interface evolution problem and we establish a weak-strong uniqueness principle in case of a two dimensional ambient space. In order to focus on the boundary effects and on the singular geometry of the evolving domains, we work for simplicity in the regime of same viscosities for the two fluids.\r\nThe core of the thesis consists in the rigorous proof of the convergence of the vectorial Allen-Cahn equation towards multiphase mean curvature flow for a suitable class of multi- well potentials and for well-prepared initial data. We even establish a rate of convergence. Our relative energy approach relies on the concept of gradient-flow calibration for branching singularities in multiphase mean curvature flow and thus enables us to overcome the limitations of other approaches. To the best of the author’s knowledge, our result is the first quantitative and unconditional one available in the literature for the vectorial/multiphase setting.\r\nThis thesis also contains a first study of weak-strong stability for planar multiphase mean curvature flow beyond the singularity resulting from a topology change. Previous weak-strong results are indeed limited to time horizons before the first topology change of the strong solution. We consider circular topology changes and we prove weak-strong stability for BV solutions to planar multiphase mean curvature flow beyond the associated singular times by dynamically adapting the strong solutions to the weak one by means of a space-time shift.\r\nIn the context of interface evolution problems, our proofs for the main results of this thesis are based on the relative energy technique, relying on novel suitable notions of relative energy functionals, which in particular measure the interface error. Our statements follow from the resulting stability estimates for the relative energy associated to the problem.\r\nAt last, we introduce a variational approach to the study of nonlinear evolution problems. This approach hinges on the minimization of a parameter dependent family of convex functionals over entire trajectories, known as Weighted Inertia-Dissipation-Energy (WIDE) functionals. We consider a class of doubly nonlinear wave equations and establish the convergence, up to subsequences, of the associated WIDE minimizers to a solution of the target problem as the parameter goes to zero." acknowledgement: The research projects contained in this thesis have received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 948819). alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Alice full_name: Marveggio, Alice id: 25647992-AA84-11E9-9D75-8427E6697425 last_name: Marveggio citation: ama: Marveggio A.

CME relies on the precise recruitment of regulators for vesicle maturation and release. Homologues of components of mammalian vesicle scission are strong candidates to be part of the scissin machinery in plants, but the precise roles of these proteins in this process is not fully understood. Here, we characterised the roles of Plant Dynamin-Related Proteins 2 (DRP2s) and SH3-domain containing protein 2 (SH3P2), the plant homologue to Dynamins’ recruiters, like Endophilin and Amphiphysin, in the CME by combining high-resolution imaging of endocytic events in vivo and characterisation of the purified proteins in vitro. Although DRP2s and SH3P2 arrive similarly late during CME and physically interact, genetic analysis of the Dsh3p1,2,3 triple-mutant and complementation assays with non-SH3P2-interacting DRP2 variants suggests that SH3P2 does not directly recruit DRP2s to the site of endocytosis. These observations imply that despite the presence of many well-conserved endocytic components, plants have acquired a distinct mechanism for CME. One Sentence Summary In contrast to predictions based on mammalian systems, plant Dynamin-related proteins 2 are recruited to the site of Clathrin-mediated endocytosis independently of BAR-SH3 proteins. acknowledged_ssus: - _id: EM-Fac - _id: LifeSc - _id: Bio article_processing_charge: No author: - first_name: Nataliia full_name: Gnyliukh, Nataliia id: 390C1120-F248-11E8-B48F-1D18A9856A87 last_name: Gnyliukh orcid: 0000-0002-2198-0509 - first_name: Alexander J full_name: Johnson, Alexander J id: 46A62C3A-F248-11E8-B48F-1D18A9856A87 last_name: Johnson orcid: 0000-0002-2739-8843 - first_name: Marie-Kristin full_name: Nagel, Marie-Kristin last_name: Nagel - first_name: Aline full_name: Monzer, Aline id: 2DB5D88C-D7B3-11E9-B8FD-7907E6697425 last_name: Monzer - first_name: Annamaria full_name: Hlavata, Annamaria id: 36062FEC-F248-11E8-B48F-1D18A9856A87 last_name: Hlavata - first_name: Erika full_name: Isono, Erika last_name: Isono - first_name: Martin full_name: Loose, Martin id: 462D4284-F248-11E8-B48F-1D18A9856A87 last_name: Loose orcid: 0000-0001-7309-9724 - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Gnyliukh N, Johnson AJ, Nagel M-K, et al.

However, the validity of this association remains to be confirmed. A second OGDHL patient cohort was recruited to carefully assess the gene-disease relationship.\r\nMethods: Using an unbiased genotype-first approach, we screened large, multiethnic aggregated sequencing datasets worldwide for biallelic OGDHL variants. We used CRISPR/Cas9 to generate zebrafish knockouts of ogdhl, ogdh paralogs, and dhtkd1 to investigate functional relationships and impact during development. Functional complementation with patient variant transcripts was conducted to systematically assess protein functionality as a readout for pathogenicity.\r\nResults: A cohort of 14 individuals from 12 unrelated families exhibited highly variable clinical phenotypes, with the majority of them presenting at least one additional variant, potentially accounting for a blended phenotype and complicating phenotypic understanding. We also uncovered extreme clinical heterogeneity and high allele frequencies, occasionally incompatible with a fully penetrant recessive disorder. Human cDNA of previously described and new variants were tested in an ogdhl zebrafish knockout model, adding functional evidence for variant reclassification. We disclosed evidence of hypomorphic alleles as well as a loss-of-function variant without deleterious effects in zebrafish variant testing also showing discordant familial segregation, challenging the relationship of OGDHL as a conventional Mendelian gene. Going further, we uncovered evidence for a complex compensatory relationship among OGDH, OGDHL, and DHTKD1 isoenzymes that are associated with neurodevelopmental disorders and exhibit complex transcriptional compensation patterns with partial functional redundancy.\r\nConclusions: Based on the results of genetic, clinical, and functional studies, we formed three hypotheses in which to frame observations: biallelic OGDHL variants lead to a highly variable monogenic disorder, variants in OGDHL are following a complex pattern of inheritance, or they may not be causative at all. Our study further highlights the continuing challenges of assessing the validity of reported disease-gene associations and effects of variants identified in these genes. This is particularly more complicated in making genetic diagnoses based on identification of variants in genes presenting a highly heterogenous phenotype such as “OGDHL-related disorders”." article_number: '102' article_processing_charge: Yes article_type: original author: - first_name: Sheng-Jia full_name: Lin, Sheng-Jia last_name: Lin - first_name: Barbara full_name: Vona, Barbara last_name: Vona - first_name: Tracy full_name: Lau, Tracy last_name: Lau - first_name: Kevin full_name: Huang, Kevin id: 3b3d2888-1ff6-11ee-9fa6-8f209ca91fe3 last_name: Huang orcid: 0000-0002-2512-7812 - first_name: Maha S. full_name: Zaki, Maha S. last_name: Zaki - first_name: Huda Shujaa full_name: Aldeen, Huda Shujaa last_name: Aldeen - first_name: Ehsan Ghayoor full_name: Karimiani, Ehsan Ghayoor last_name: Karimiani - first_name: Clarissa full_name: Rocca, Clarissa last_name: Rocca - first_name: Mahmoud M. full_name: Noureldeen, Mahmoud M. last_name: Noureldeen - first_name: Ahmed K. full_name: Saad, Ahmed K. last_name: Saad - first_name: Cassidy full_name: Petree, Cassidy last_name: Petree - first_name: Tobias full_name: Bartolomaeus, Tobias last_name: Bartolomaeus - first_name: Rami full_name: Abou Jamra, Rami last_name: Abou Jamra - first_name: Giovanni full_name: Zifarelli, Giovanni last_name: Zifarelli - first_name: Aditi full_name: Gotkhindikar, Aditi last_name: Gotkhindikar - first_name: Ingrid M. full_name: Wentzensen, Ingrid M. last_name: Wentzensen - first_name: Mingjuan full_name: Liao, Mingjuan last_name: Liao - first_name: Emalyn Elise full_name: Cork, Emalyn Elise last_name: Cork - first_name: Pratishtha full_name: Varshney, Pratishtha last_name: Varshney - first_name: Narges full_name: Hashemi, Narges last_name: Hashemi - first_name: Mohammad Hasan full_name: Mohammadi, Mohammad Hasan last_name: Mohammadi - first_name: Aboulfazl full_name: Rad, Aboulfazl last_name: Rad - first_name: Juanita full_name: Neira, Juanita last_name: Neira - first_name: Mehran Beiraghi full_name: Toosi, Mehran Beiraghi last_name: Toosi - first_name: Cordula full_name: Knopp, Cordula last_name: Knopp - first_name: Ingo full_name: Kurth, Ingo last_name: Kurth - first_name: Thomas D. full_name: Challman, Thomas D. last_name: Challman - first_name: Rebecca full_name: Smith, Rebecca last_name: Smith - first_name: Asmahan full_name: Abdalla, Asmahan last_name: Abdalla - first_name: Thomas full_name: Haaf, Thomas last_name: Haaf - first_name: Mohnish full_name: Suri, Mohnish last_name: Suri - first_name: Manali full_name: Joshi, Manali last_name: Joshi - first_name: Wendy K. full_name: Chung, Wendy K. last_name: Chung - first_name: Andres full_name: Moreno-De-Luca, Andres last_name: Moreno-De-Luca - first_name: Henry full_name: Houlden, Henry last_name: Houlden - first_name: Reza full_name: Maroofian, Reza last_name: Maroofian - first_name: Gaurav K. full_name: Varshney, Gaurav K. last_name: Varshney citation: ama: Lin S-J, Vona B, Lau T, et al.

Because the structures’ “architectures” vary widely—with elements such as beams, thin shells, and solid bulks—it is difficult to explore them using existing representations. Generic approaches like voxel grids are versatile, but it is cumbersome to represent and edit individual structures; architecture-specific approaches address these issues, but are incompatible with one another. By contrast, our procedural graph succinctly represents the construction process for any structure using a simple skeleton annotated with spatially varying thickness. To express the highly constrained triply periodic minimal surfaces (TPMS) in this manner, we present the first fully automated version of the conjugate surface construction method, which allows novices to create complex TPMS from intuitive input. We demonstrate our representation’s expressiveness, accuracy, and compactness by constructing a wide range of established structures and hundreds of novel structures with diverse architectures and material properties. We also conduct a user study to verify our representation’s ease-of-use and ability to expand engineers’ capacity for exploration. acknowledgement: "The authors thank Mina Konaković Luković and Michael Foshey for their early contributions to this project, David Palmer and Paul Zhang for their insightful discussions about minimal surfaces and the CSCM, Julian Panetta for providing the Elastic Textures code, and Hannes Hergeth for his feedback and support.

However, the mechanism by which endogenous RNAs repress transcription remains unclear. Here we present cryo-electron microscopy structures of Pol II bound to Alu RNA, which reveal that Alu RNA mimics how DNA and RNA bind to Pol II during transcription elongation. Further, we show how domains of the general transcription factor TFIIF affect complex dynamics and control repressive activity. Together, we reveal how a non-coding RNA can regulate mammalian gene expression. acknowledged_ssus: - _id: LifeSc - _id: EM-Fac - _id: PreCl acknowledgement: "We thank B.

We assume that our finite fermionic system is close to fully spin polarized while being doped by a hole and an impurity fermion with opposite spin. Our setup involves ferromagnetic couplings among the particles in different bands, leading to the development of strong spin-transport correlations in an intermediate interaction regime. Interactions are then strong enough to lift the degeneracy among singlet and triplet spin configurations in the well of the spin impurity but not strong enough to prohibit hole-induced magnetic excitations to the singlet state. Despite the strong spin-hole correlations, the system exhibits spin-charge deconfinement allowing for long-range entanglement of the spatial and spin degrees of freedom." acknowledgement: This work has been funded by the Cluster of Excellence “Advanced Imaging of Matter” of the Deutsche Forschungsgemeinschaft (DFG)-EXC 2056-Project ID No. 390715994.

We show that the dipolar nature of the condensate and of the impurity results in anisotropic relaxation dynamics, in particular, anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench dynamics is strongly affected by the interplay between dipolar anisotropy and trap geometry.

Conventional MSI experiments require to predefine the surface of interest based on photographic or microscopic images. Typically, these boundaries can no longer be changed or adjusted once the experiment has been started. In terms of a more interactive approach we recently developed a pen-like ionization interface which is directly connected to the mass spectrometer. The device allows the user to ionize chemicals by desorption electrospray ionization (DESI) and to freely move the interface over a surface of interest. A mini camera, which is mounted on the tip of the pen, magnifies the desorption area and enables a simple positioning of the pen. The combination of optical data from the camera module and chemical data obtained by mass analysis facilitates a novel type of imaging experiment: interactive mass spectrometry imaging (IMSI). For this application, we present a novel approach for a robust, optical flow-based motion detection. While the live video stream from the camera is used to track the pen''s motion across the surface a post-acquisition algorithm correlates the coordinates of the pen trajectory with respective mass spectra obtained from a simultaneous mass spectrometric data acquisition. This algorithm is no longer dependent on a single, manually applied optical marker on the sample surface, which has to be visible on all video frames throughout the analysis. The advanced DESI-IMSI method was successfully tested on inkjet-printed letters as well as mouse brain tissue samples. Validation of the results was done by comparing DESI-IMSI with standard DESI-MSI data.' acknowledgement: We would like to thank Marco Sealey Cardona, PhD for help with the mouse brain samples and acknowledge the financial support by 1669 Förderkreis of the University of Innsbruck, Austria Wirtschaftsservice (AWS), D.

Here, we report that the transcription factor Forkhead Box G1 (Foxg1) regulates gliogenesis in the mouse neocortex via distinct cell-autonomous roles in progenitors and in postmitotic neurons that regulate different aspects of the gliogenic FGF signalling pathway. We demonstrate that loss of Foxg1 in cortical progenitors at neurogenic stages causes premature astrogliogenesis. We identify a novel FOXG1 target, the pro-gliogenic FGF pathway component Fgfr3, which is suppressed by FOXG1 cell-autonomously to maintain neurogenesis. Furthermore, FOXG1 can also suppress premature astrogliogenesis triggered by the augmentation of FGF signalling. We identify a second novel function of FOXG1 in regulating the expression of gliogenic ligand FGF18 in new born neocortical upper-layer neurons. Loss of FOXG1 in postmitotic neurons increases Fgf18 expression and enhances gliogenesis in the progenitors. These results fit well with the model that new born neurons secrete cues that trigger progenitors to produce the next wave of cell types, astrocytes. If FGF signalling is attenuated in Foxg1 null progenitors, they progress to oligodendrocyte production. Therefore, loss of FOXG1 transitions the progenitor to a gliogenic state, producing either astrocytes or oligodendrocytes depending on FGF signalling levels. Our results uncover how FOXG1 integrates extrinsic signalling via the FGF pathway to regulate the sequential generation of neurons, astrocytes, and oligodendrocytes in the cerebral cortex. acknowledgement: "We thank Dr. Shital Suryavanshi and the animal house staff of the Tata Institute of\r\nFundamental Research (TIFR) for their excellent support; Gord Fishell and Goichi Miyoshi for\r\nthe Foxg1 floxed mouse line; Hiroshi Kawasaki for the plasmids pCAG-FGF8 and pCAGsFGFR3c.

This results in a very substantial speedup of assembly in physiological regimes, and could help with understanding the dynamics of actin and intermediate filaments in biological processes such as wound healing and cell division. acknowledgement: The authors thank C´ecile Leduc and Duc-Quang Tran for invaluable help with understanding the experimental behavior of intermediate filaments, and Raphael Voituriez, Nicolas Levernier, and Alexander Grosberg for fruitful discussion on the theoretical model.

Such non-causal firing is contrary to the tenet of spikes as a means of communication, and its purpose remains unclear. We propose that self-initiated firing can serve as a release valve to protect neurons from the toxic conditions arising in mitochondria from lower-than-baseline energy consumption. To demonstrate the viability of our hypothesis, we built a set of models that incorporate recent experimental results indicating homeostatic control of metabolic products—Adenosine triphosphate (ATP), adenosine diphosphate (ADP), and reactive oxygen species (ROS)—by changes in firing. We explore the relationship of metabolic cost of spiking with its effect on the temporal patterning of spikes and reproduce experimentally observed changes in intrinsic firing in the fruitfly dorsal fan-shaped body neuron in a model with ROS-modulated potassium channels. We also show that metabolic spiking homeostasis can produce indefinitely sustained avalanche dynamics in cortical circuits. Our theory can account for key features of neuronal activity observed in many studies ranging from ion channel function all the way to resting state dynamics. We finish with a set of experimental predictions that would confirm an integrated, crucial role for metabolically regulated spiking and firmly link metabolic homeostasis and neuronal function. acknowledgement: We thank Prof. C.

Using a novel statistical estimator and theoretical modeling, both developed in the framework of maximum entropy models, we reveal highly structured CA1 cell-cell interactions in male rats during open field exploration. The statistics of these interactions depend on whether the animal is in a familiar or novel environment. In both conditions the circuit interactions optimize the encoding of spatial information, but for regimes that differ in the informativeness of their spatial inputs. This structure facilitates linear decodability, making the information easy to read out by downstream circuits. Overall, our findings suggest that the efficient coding hypothesis is not only applicable to individual neuron properties in the sensory periphery, but also to neural interactions in the central brain. acknowledgement: M.N. was supported by the European Union Horizon 2020 Grant 665385.

Here we explore how natural selection acts on mutants that have the same reproductive rate, but different population structures. In our framework, population structure is given by a graph that specifies where offspring can disperse. The invading mutant disperses offspring on a different graph than the resident wild-type. We find that more densely connected dispersal graphs tend to increase the invader’s fixation probability, but the exact relationship between structure and fixation probability is subtle. We present three main results. First, we prove that if both invader and resident are on complete dispersal graphs, then removing a single edge in the invader’s dispersal graph reduces its fixation probability. Second, we show that for certain island models higher invader’s connectivity increases its fixation probability, but the magnitude of the effect depends on the exact layout of the connections. Third, we show that for lattices the effect of different connectivity is comparable to that of different fitness: for large population size, the invader’s fixation probability is either constant or exponentially small, depending on whether it is more or less connected than the resident.' acknowledgement: K.C. acknowledges support from the ERC CoG 863818(ForM-SMArt).

For example, a rigid cage with small windows can efficiently protect its contents from the environment; in contrast, tube-shaped, flexible hosts with large openings and an easily accessible cavity are ideally suited for catalysis. Here, we report a “Janus” nature of a Pd6L4 coordination host previously reported to exist exclusively as a tube isomer (T). We show that upon encapsulating various tetrahedrally shaped guests, T can reconfigure into a cage-shaped host (C) in quantitative yield. Extracting the guest affords empty C, which is metastable and spontaneously relaxes to T, and the T⇄C interconversion can be repeated for multiple cycles.

However, elusive active centers and reaction mechanism issues inhibit further optimization of its performance. In this work, advanced microkinetic modeling with the adsorbate–adsorbate interaction and nanoparticle size effect based on first-principles calculations is developed. A full mechanism uncovering the significance of adsorbate–adsorbate interaction is determined on Pd nanoparticles. We demonstrate unambiguously that Pd(100) with main coverage species of O2 and H is beneficial to H2O2 production, being consistent with experimental operando observation, while H2O forms on Pd(111) covered by O species and Pd(211) covered by O and OH species. Kinetic analyses further enable quantitative estimation of the influence of temperature, pressure, and particle size. Large-size Pd nanoparticles are found to achieve a high H2O2 reaction rate when the operating conditions are moderate temperature and higher oxygen partial pressure. We reveal that specific facets of the Pd nanoparticles are crucial factors for their selectivity and activity. Consistent with the experiment, the production of H2O2 is discovered to be more favorable on Pd nanoparticles containing Pd(100) facets. The ratio of H2/O2 induces substantial variations in the coverage of intermediates of O2 and H on Pd(100), resulting in a change in product selectivity. acknowledgement: The authors acknowledge the financial support from the National Natural Science Foundation of China (22008211, 92045303, U21A20298), the National Key Research and Development Project of China (2021YFA1500900, 2022YFE0113800), and Zhejiang Innovation Team (2017R5203). article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Jinyan full_name: Zhao, Jinyan last_name: Zhao - first_name: Zihao full_name: Yao, Zihao last_name: Yao - first_name: Rhys full_name: Bunting, Rhys id: 91deeae8-1207-11ec-b130-c194ad5b50c6 last_name: Bunting orcid: 0000-0001-6928-074X - first_name: P. full_name: Hu, P. last_name: Hu - first_name: Jianguo full_name: Wang, Jianguo last_name: Wang citation: ama: Zhao J, Yao Z, Bunting R, Hu P, Wang J.
