The films were differentiated in terms of porosity and roughness. The XPS N1s core levels of the N2 gas in presence of the SiO2 samples showed variations in width, binding energy and line shape. The width correlated with the surface charge induced in the dielectric films upon X-ray irradiation. The observed different binding energies observed for the N1s peak can only partly be associated with intrinsic work function differences between the samples, opening the possibility that the effect of physisorption at room temperature could be detected by a shift in the measured binding energy. However, the signals also show an increasing asymmetry with rising surface charge. This might be associated with the formation of vertical electrical gradients within the dielectric porous thin films, which complicates the assignment of binding energy positions to specific surface-related effects. With the support of Monte Carlo and first principles density functional theory calculations, the observed shifts were discussed in terms of the possible formation of transitory dipoles upon N2 physisorption within the porous SiO2 films."}],"title":"Challenges in the interpretation of gas core levels for the determination of gas-solid interactions within dielectric porous films by ambient pressure XPS","keyword":["Surfaces","Coatings and Films","Condensed Matter Physics","Surfaces and Interfaces","General Physics and Astronomy","General Chemistry"],"user_id":"23547","type":"journal_article","quality_controlled":"1","publication":"Applied Surface Science","article_number":"154525","volume":604},{"doi":"10.1002/admi.202200245","abstract":[{"text":"In the spatial confinement of cylindrical mesopores with diameters of a few nanometers, water molecules experience restrictions in hydrogen bonding. This leads to a different behavior regarding the molecular orientational freedom (‘structure of water') compared to the bulk liquid state. In addition to the pore size, the behavior is also strongly affected by the strength of the pore wall-to-water interactions, that is, the pore wall polarity. In this work, this is studied both experimentally and theoretically. The surface polarity of mesoporous silica (SiO2) is modified by functionalization with trimethylsilyl moieties, resulting in a change from a hydrophilic (pristine) to a hydrophobic pore wall. The mesopore surface is characterized by N2 and H2O sorption experiments. Those results are combined with IR spectroscopy to investigate pore wall-to-water interactions leading to different structures of water in the mesopore. Furthermore, the water's structure is studied theoretically to gain deeper insight into the interfacial interactions. For this purpose, the structure of water is analyzed by pairing densities, coordination, and angular distributions with a novel adaptation of surface-specific sum-frequency generation calculation for pore environments.","lang":"eng"}],"title":"The Structure of Water in Silica Mesopores – Influence of the Pore Wall Polarity","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202200245","open_access":"1"}],"keyword":["Mechanical Engineering","Mechanics of Materials"],"user_id":"23547","oa":"1","type":"journal_article","quality_controlled":"1","publication":"Advanced Materials Interfaces","article_number":"2200245","issue":"20","volume":9,"intvolume":" 9","article_type":"original","author":[{"last_name":"Weinberger","id":"11848","full_name":"Weinberger, Christian","first_name":"Christian"},{"full_name":"Zysk, Frederik","first_name":"Frederik","last_name":"Zysk","id":"14757"},{"last_name":"Hartmann","full_name":"Hartmann, Marc","first_name":"Marc"},{"first_name":"Naveen","full_name":"Kaliannan, Naveen","last_name":"Kaliannan"},{"full_name":"Keil, Waldemar","first_name":"Waldemar","last_name":"Keil"},{"first_name":"Thomas","full_name":"Kühne, Thomas","id":"49079","last_name":"Kühne"},{"full_name":"Tiemann, Michael","first_name":"Michael","id":"23547","last_name":"Tiemann","orcid":"0000-0003-1711-2722"}],"department":[{"_id":"613"},{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"304"}],"citation":{"short":"C.

This approach is based on the reduced density-matrix functional theory (RDMFT) formulation of the electronic structure problem. For that purpose, the density-matrix functional of the full system is decomposed into an indirectly coupled sum of density-matrix functionals for all its subsystems using the adaptive cluster approximation to RDMFT. The approximations involved in the decomposition and the adaptive cluster approximation itself can be systematically converged to the exact result. The solutions for the density-matrix functionals of the effective subsystems involves a constrained minimization over many-particle states that are approximated by parametrized trial states on the quantum computer similarly to the variational quantum eigensolver. The independence of the density-matrix functionals of the effective subsystems introduces a new level of parallelization and allows for the computational treatment of much larger molecules on a quantum computer with a given qubit count. In addition, for the proposed algorithm techniques are presented to reduce the qubit count, the number of quantum programs, as well as its depth. The evaluation of a density-matrix functional as the essential part of our approach is demonstrated for Hubbard-like systems on IBM quantum computers based on superconducting transmon qubits.","lang":"eng"}],"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"main_file_link":[{"open_access":"1","url":"https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.4.033160"}],"oa":"1","user_id":"75963"},{"user_id":"75963","citation":{"bibtex":"@article{Gavini_Baroni_Blum_Bowler_Buccheri_Chelikowsky_Das_Dawson_Delugas_Dogan_et al._2022, title={Roadmap on Electronic Structure Codes in the Exascale Era}, journal={arXiv:2209.12747}, author={Gavini, Vikram and Baroni, Stefano and Blum, Volker and Bowler, David R. and Buccheri, Alexander and Chelikowsky, James R. and Das, Sambit and Dawson, William and Delugas, Pietro and Dogan, Mehmet and et al.}, year={2022} }","mla":"Gavini, Vikram, et al. “Roadmap on Electronic Structure Codes in the Exascale Era.” ArXiv:2209.12747, 2022.","short":"V.

Herein, guided by density functional theory (DFT) calculations, an efficient metal-free electrocatalyst is demonstrated via covalently bonding BP nanosheets with graphitic carbon nitride (denoted BP-CN-c). The polarized PN covalent bonds in BP-CN-c can efficiently regulate the electron transfer from BP to graphitic carbon nitride and significantly promote the OOH* adsorption on phosphorus atoms. Impressively, the oxygen evolution reaction performance of BP-CN-c (overpotential of 350 mV at 10 mA cm−2, 90\\% retention after 10 h operation) represents the state-of-the-art among the reported BP-based metal-free catalysts. Additionally, BP-CN-c exhibits a small half-wave overpotential of 390 mV for oxygen reduction reaction, representing the first bifunctional BP-based metal-free oxygen catalyst. Moreover, ZABs are assembled incorporating BP-CN-c cathodes, delivering a substantially higher peak power density (168.3 mW cm−2) than the Pt/C+RuO2-based ZABs (101.3 mW cm−2). The acquired insights into interfacial covalent bonds pave the way for the rational design of new and affordable metal-free catalysts."}],"doi":"https://doi.org/10.1002/adma.202008752","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"title":"Interfacial Covalent Bonds Regulated Electron-Deficient 2D Black Phosphorus for Electrocatalytic Oxygen Reactions","keyword":["2D materials","bifunctional oxygen electrocatalysts","black phosphorus","oxygen evolution reaction","zinc–air batteries"],"user_id":"71051","type":"journal_article","publication":"Advanced Materials","issue":"20","volume":33,"page":"2008752","intvolume":" 33","author":[{"last_name":"Wang","full_name":"Wang, Xia","first_name":"Xia"},{"orcid":"https://orcid.org/0000-0003-4667-9744","last_name":"Kormath Madam Raghupathy","id":"71692","first_name":"Ramya","full_name":"Kormath Madam Raghupathy, Ramya"},{"last_name":"Querebillo","first_name":"Christine Joy","full_name":"Querebillo, Christine Joy"},{"last_name":"Liao","full_name":"Liao, Zhongquan","first_name":"Zhongquan"},{"full_name":"Li, Dongqi","first_name":"Dongqi","last_name":"Li"},{"last_name":"Lin","first_name":"Kui","full_name":"Lin, Kui"},{"last_name":"Hantusch","first_name":"Martin","full_name":"Hantusch, Martin"},{"last_name":"Sofer","full_name":"Sofer, Zdeněk","first_name":"Zdeněk"},{"first_name":"Baohua","full_name":"Li, Baohua","last_name":"Li"},{"last_name":"Zschech","full_name":"Zschech, Ehrenfried","first_name":"Ehrenfried"},{"full_name":"Weidinger, Inez M.","first_name":"Inez M.","last_name":"Weidinger"},{"id":"49079","last_name":"Kühne","first_name":"Thomas","full_name":"Kühne, Thomas"},{"orcid":"0000-0001-6179-1545","last_name":"Mirhosseini","id":"71051","first_name":"Hossein","full_name":"Mirhosseini, Hossein"},{"last_name":"Yu","full_name":"Yu, Minghao","first_name":"Minghao"},{"last_name":"Feng","first_name":"Xinliang","full_name":"Feng, Xinliang"}],"department":[{"_id":"304"}],"citation":{"short":"X.

In fact{,} our results disclose novel morphologies with moieties not previously considered for C3N5.

Intercalation of anions into a graphite positive electrode provides high operating voltage and improved energy density to such dual-ion batteries. In this work, we have performed a combinatorial study of graphite intercalation compounds considering four anions, namely hexafluorophosphate (PF\r\n \r\n\r\n\r\n \r\n \r\n \r\n \r\n 6\r\n \r\n \r\n −\r\n \r\n \r\n \r\n \r\n ), perchlorate (ClO\r\n \r\n\r\n\r\n \r\n \r\n \r\n \r\n 4\r\n \r\n \r\n −\r\n \r\n \r\n \r\n \r\n ), bis(fluorosulfonyl)imide (FSI−), and bis(trifluoromethanesulfonyl)imide (TFSI−), via first-principles calculations. The structural properties and energetics of the intercalation compounds are compared based on different sizes, geometries, and the physical and chemical properties of the intercalated anions. The staging mechanism of anion intercalation into graphite and the specific capacities, and voltage profiles of the intercalated compounds are investigated. A comparison regarding battery electrochemistry is also done with available experimental observations. Our calculated intercalation energies and voltage profiles show that the initial anion intercalation into graphite is less favorable than subsequent ones for all the anions considered in this study. Although the effect of the size of anions in a graphite cathode on various properties of the intercalated compounds is not as significant as the size of cations in a graphite anode, some distinction between the studied anions can still be made. Among the studied anions, the intercalation compounds based on PF\r\n \r\n\r\n\r\n \r\n \r\n \r\n \r\n 6\r\n \r\n \r\n −\r\n \r\n \r\n \r\n \r\n are the most stable ones. These PF\r\n \r\n\r\n\r\n \r\n \r\n \r\n \r\n 6\r\n \r\n \r\n −\r\n \r\n \r\n \r\n \r\n anions cause relatively small structural deformations of the graphite and have the highest oxidative ability, highest onset voltage, and highest diffusion barrier along the graphene sheets. The overall small diffusion barriers of the anions within graphite explain the high rate capability of dual-ion batteries."}],"doi":"10.1088/2053-1591/ac1965","_id":"33655","date_updated":"2022-10-10T08:23:07Z","date_created":"2022-10-10T08:22:50Z","publisher":"IOP Publishing","publication_identifier":{"issn":["2053-1591"]},"year":"2021","language":[{"iso":"eng"}],"status":"public","citation":{"ama":"Chugh M, Jain M, Wang G, Nia AS, Mirhosseini H, Kühne T.

The assignment is then based on the calculation of partial Raman activities arising from self- and/or cross-correlations between different types of Wannier functions in the system. Different types of Wannier functions can be distinguished based on their spatial spread.
