In this work, we\r\ntake up the idea of the submatrix method and apply it to the DFT computations\r\nin the software package CP2K. For that purpose, we transform the underlying\r\nnumeric operations on distributed, large, sparse matrices into computations on\r\nlocal, much smaller and nearly dense matrices. This allows us to exploit the\r\nfull floating-point performance of modern CPUs and to make use of dedicated\r\naccelerator hardware, where performance has been limited by memory bandwidth\r\nbefore.

The “polar flattening” effect that causes a slight σ-hole to form on hydrogen atoms is strengthened when the bond is stretched, so that the σ-hole becomes more positive and hydrogen bonding stronger. In opposition to this electronic effect, path-integral ab initio molecular-dynamics simulations show that the nuclear quantum effect weakens the hydrogen bond in the water dimer. Thus, static electronic effects strengthen the hydrogen bond in H2O relative to D2O, whereas nuclear quantum effects weaken it. These quantum fluctuations are stronger for the water dimer than in bulk water.","lang":"eng"}],"user_id":"71692","author":[{"first_name":"Timothy","full_name":"Clark, Timothy","last_name":"Clark"},{"last_name":"Heske","id":"53238","first_name":"Julian Joachim","full_name":"Heske, Julian Joachim"},{"id":"49079","last_name":"Kühne","full_name":"Kühne, Thomas","first_name":"Thomas"}],"keyword":["ab initio calculations","bond theory","hydrogen bonds","isotope effects","solvent effects"],"publication":"ChemPhysChem","status":"public","date_created":"2019-09-13T13:41:57Z","volume":20,"intvolume":" 20","_id":"13225","issue":"0","year":"2019","type":"journal_article","citation":{"mla":"Clark, Timothy, et al. “Opposing Electronic and Nuclear Quantum Effects on Hydrogen Bonds in H2O and D2O.” ChemPhysChem, vol. 20, no. 0, 2019, pp. 1–6, doi:10.1002/cphc.201900839.","bibtex":"@article{Clark_Heske_Kühne_2019, title={Opposing Electronic and Nuclear Quantum Effects on Hydrogen Bonds in H2O and D2O}, volume={20}, DOI={10.1002/cphc.201900839}, number={0}, journal={ChemPhysChem}, author={Clark, Timothy and Heske, Julian Joachim and Kühne, Thomas}, year={2019}, pages={1–6} }","ama":"Clark T, Heske JJ, Kühne T.

Depending on the condensation temperature of HAT-CN{,} nitrogen contents of more than 30 at% can be reached. In general{,} these carbons show adsorption properties which are comparable to those known for zeolites but their pore size can be adjusted over a wider range. At condensation temperatures of 525 °C and below{,} the uptake of nitrogen gas remains negligible due to size exclusion{,} but the internal pores are large and polarizing enough that CO2 can still adsorb on part of the internal surface. This leads to surprisingly high CO2 adsorption capacities and isosteric heat of adsorption of up to 52 kJ mol−1. Theoretical calculations show that this high binding enthalpy arises from collective stabilization effects from the nitrogen atoms in the C2N layers surrounding the carbon atom in the CO2 molecule and from the electron acceptor properties of the carbon atoms from C2N which are in close proximity to the oxygen atoms in CO2. A true CO2 molecular sieving effect is achieved for the first time in such a metal-free organic material with zeolite-like properties{,} showing an IAST CO2/N2 selectivity of up to 121 at 298 K and a N2/CO2 ratio of 90/10 without notable changes in the CO2 adsorption properities over 80 cycles.","lang":"eng"}],"user_id":"71692","title":"Controlling the strength of interaction between carbon dioxide and nitrogen-rich carbon materials by molecular design","author":[{"first_name":"Ralf","full_name":"Walczak, Ralf","last_name":"Walczak"},{"first_name":"Aleksandr","full_name":"Savateev, Aleksandr","last_name":"Savateev"},{"id":"53238","last_name":"Heske","full_name":"Heske, Julian Joachim","first_name":"Julian Joachim"},{"last_name":"Tarakina","first_name":"Nadezda V.","full_name":"Tarakina, Nadezda V."},{"last_name":"Sahoo","full_name":"Sahoo, Sudhir","first_name":"Sudhir"},{"last_name":"Epping","full_name":"Epping, Jan D.","first_name":"Jan D."},{"id":"49079","last_name":"Kühne","full_name":"Kühne, Thomas","first_name":"Thomas"},{"last_name":"Kurpil","full_name":"Kurpil, Bogdan","first_name":"Bogdan"},{"full_name":"Antonietti, Markus","first_name":"Markus","last_name":"Antonietti"},{"last_name":"Oschatz","first_name":"Martin","full_name":"Oschatz, Martin"}],"publisher":"The Royal Society of Chemistry","department":[{"_id":"304"}],"publication":"Sustainable Energy Fuels","status":"public","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"date_created":"2019-09-16T10:39:25Z","publication_status":"published","_id":"13236","date_updated":"2022-01-06T06:51:31Z","doi":"10.1039/C9SE00486F","language":[{"iso":"eng"}],"citation":{"ieee":"R.

In this work, three grain boundary models, one coherent twin boundary and two twin boundaries with dislocation cores, are considered. Total energy calculations show that all alkali metals tend to segregate at the grain boundaries. In addition, the segregation of alkali atoms is more pronounced at the grain boundaries with the dislocation cores. The diffusion of alkali metals along and near grain boundaries is studied as well. The results show that the diffusion of alkali atoms in the grain boundary models is faster than within the bulk. In addition, the ion exchange between Na and Rb atoms at the grain boundaries leads to the Rb enrichment at the grain boundaries and the increase of the Na concentration in the bulk. While the effects of Na and Rb point defects on the electronic structure of the grain boundary with the anion-core dislocation are similar, Rb atoms passivate the grain boundary with the cation-core dislocation more effectively than Na. This can explain the further improvement of the solar cell performance after the RbF-postdeposition treatment."}],"article_type":"original","volume":11,"date_created":"2019-09-16T10:18:18Z","status":"public","publication":"ACS Applied Materials & Interfaces","author":[{"last_name":" Chugh","full_name":" Chugh, Manjusha","first_name":"Manjusha"},{"last_name":"Kühne","full_name":"Kühne, Thomas D.","first_name":" Thomas D."},{"id":"71051","last_name":"Mirhosseini","full_name":"Mirhosseini, Hossein","orcid":"https://orcid.org/0000-0001-6179-1545","first_name":"Hossein"}],"publisher":"American Chemical Society"},{"language":[{"iso":"eng"}],"date_updated":"2023-09-26T11:45:02Z","doi":"10.4208/cicp.OA-2018-0053","department":[{"_id":"27"},{"_id":"518"},{"_id":"304"},{"_id":"104"}],"project":[{"_id":"32","grant_number":"PL 595/2-1 / 320898746","name":"Performance and Efficiency in HPC with Custom Computing"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"external_id":{"arxiv":["1703.02456"]},"title":"A General Algorithm to Calculate the Inverse Principal p-th Root of Symmetric Positive Definite Matrices","page":"564-585","type":"journal_article","citation":{"ieee":"D.

We found that H interstitial defects (when one H atom is surrounded by four Se atoms) and HCu (when a H atom is replacing a Cu atom) are the most stable defects. Whereas these H substitutional defects remain neutral, H interstitial defects act as donor defects and are detrimental to the cell performance. The incorporation of H2 into the CISe lattice, on the other hand, is harmless to the p-type conductivity. Oxygen atoms tend to either substitute Se atoms in the CISe lattice or form interstitial defects, though the formation of substitutional defects is more favorable. All oxygen point defects have high formation energies, which results in a low concentration of these defects in CISe. However, the presence of oxygen in the system leads to the formation of secondary phases such as In2O3 and InCuO2. In addition to the point defects, we studied the adsorption of H2O molecules on a defect-free surface and a surface with a (2VCu + InCu) defect using the ab initio thermodynamics technique. Our results indicate that the dissociative water adsorption on the CISe surface is energetically unfavorable. Furthermore, in order to obtain a water-free surface, the surface with defects has to be calcined at a higher temperature compared to the defect-free surface.","lang":"eng"}],"user_id":"71051","page":"21202-21209","citation":{"mla":"Sahoo, Sudhir, et al. “Theoretical Investigation of Interaction of CuInSe2 Absorber Material with Oxygen, Hydrogen, and Water.” J.

High-throughput calculations were employed to find the compounds that satisfies our screening criteria. Our screening strategy was based on the size of band gaps, the values of hole effective masses, and p-type dopability. Our search led to the identification of seven promising compounds (IrSbS, Ba2GeSe4, Ba2SiSe4, Ba(BSe3)2, VCu3S4, NbCu3Se4, and CuBS2) as potential TCM candidates. In addition, branch point energy and optical absorption spectra calculations support our findings. Our results open a new direction for the design and development of p-type TCMs."}],"user_id":"71051","language":[{"iso":"eng"}],"date_updated":"2022-07-21T09:42:32Z","doi":"10.1021/acs.chemmater.8b02719","department":[{"_id":"304"}],"publication_status":"published","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"title":"Database screening of ternary chalcogenides for p-type transparent conductors"},{"doi":"10.1002/jcc.25641","_id":"13405","date_updated":"2023-04-20T14:24:11Z","language":[{"iso":"eng"}],"citation":{"ieee":"P.
