We present a comprehensive study of a straightforward synthesis method via direct immobilization of several phosphonic acids and phosphoric acid esters on various mesoporous silicas in a Dean–Stark apparatus with toluene as the solvent. Due to the utilization of azeotropic distillation, there was no need to dry phosphonic acids, phosphoric acid esters, solvents, or silicas prior to synthesis. In addition to modeling phosphonic acids, immobilization of the important biomolecule adenosine monophosphate (AMP) on the porous supports was also investigated.

For that purpose, we determined the ice melting temperature in pores of various size (pore radii between 1.9 and 11.1 nm) in water and aqueous solutions up to high total solute molality (up to about 12 mol kg–1) using differential scanning calorimetry. We found that both electrolytes reduce the ice melting temperature within the pores. An exception is the melting of ice in the smallest pores, which does not seem to be affected by the presence of solutes, most likely owing to an exclusion of the ions from entering the pores. For all other pores, we observed that the ice melting temperature decreases as a function of pore size and electrolyte concentration. Using thermodynamic considerations as well as additional experimental data we developed a parametrization that can be used to predict the ice melting point as a function of pore size and total solute molality. For that purpose, we extended a formulation of the effective water activity of aqueous solutions under mechanical pressure toward its application in confinement and tested this new parametrization on literature data.","lang":"eng"}],"date_created":"2021-10-08T10:41:52Z","type":"journal_article","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"title":"Phase Transitions of Ice in Aqueous Salt Solutions within Nanometer-Sized Pores","status":"public","year":"2019","author":[{"full_name":"Jantsch, Evelyn","last_name":"Jantsch","first_name":"Evelyn"},{"full_name":"Weinberger, Christian","last_name":"Weinberger","first_name":"Christian","id":"11848"},{"id":"23547","last_name":"Tiemann","orcid":"0000-0003-1711-2722","first_name":"Michael","full_name":"Tiemann, Michael"},{"last_name":"Koop","first_name":"Thomas","full_name":"Koop, Thomas"}],"publication_identifier":{"issn":["1932-7447","1932-7455"]},"publication_status":"published","date_updated":"2023-03-08T08:31:45Z","article_type":"original","page":"24566-24574","_id":"25904","language":[{"iso":"eng"}],"user_id":"23547","doi":"10.1021/acs.jpcc.9b06527"},{"citation":{"mla":"Lehmann, Tim, et al. <i>Phase Coupling of Bilateral Motor Areas Decreases from Bipedal to Single Leg Stance</i>. 2019.","bibtex":"@inproceedings{Lehmann_Büchel_Cockcroft_Abegail Louw_Baumeister_2019, title={Phase Coupling of Bilateral Motor Areas Decreases from Bipedal to Single Leg Stance}, author={Lehmann, Tim and Büchel, Daniel and Cockcroft, John and Abegail Louw, Quinette and Baumeister, Jochen}, year={2019} }","ama":"Lehmann T, Büchel D, Cockcroft J, Abegail Louw Q, Baumeister J.

The material can be applied as a sensitive layer for H2S monitoring, e.g., in biogas gas plants. CuO nanoparticles are embedded in a rigid, nanoporous silica (SiO2) matrix to form an electrical percolating network of low conducting CuO and, upon exposure to H2S, highly conducting copper(II) sulphide (CuS) particles. By steric hindrance due to the silica pore walls, the structure of the network is maintained even though the reversible reaction of CuO to CuS is accompanied by significant volume expansion. The conducting state of the percolating network can be controlled by a variety of parameters, such as temperature, electrode layout, and network topology of the porous silica matrix. The latter means that this new type of sensing material has a structure-encoded detection limit for H2S, which offers new application opportunities. The fabrication process of the mesoporous CuO@SiO2 composite as well as the sensor design and characteristics are described in detail. In addition, theoretical modeling of the percolation effect by Monte-Carlo simulations yields deeper insight into the underlying percolation mechanism and the observed response characteristics."}],"publication":"Advanced Functional Materials","doi":"10.1002/adfm.201904505","language":[{"iso":"eng"}],"article_number":"1904505","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adfm.201904505","open_access":"1"}],"article_type":"original","publication_status":"published","date_updated":"2023-03-22T09:11:49Z","author":[{"full_name":"Paul, Andrej","last_name":"Paul","first_name":"Andrej"},{"first_name":"Bertram","last_name":"Schwind","full_name":"Schwind, Bertram"},{"id":"11848","full_name":"Weinberger, Christian","last_name":"Weinberger","first_name":"Christian"},{"id":"23547","full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann"},{"first_name":"Thorsten","last_name":"Wagner","full_name":"Wagner, Thorsten"}],"publication_identifier":{"issn":["1616-301X","1616-3028"]},"title":"Gas Responsive Nanoswitch: Copper Oxide Composite for Highly Selective H2S Detection","year":"2019"},{"volume":100,"user_id":"49063","_id":"14544","page":"155308","status":"public","project":[{"name":"TRR 142","_id":"53"},{"_id":"55","name":"TRR 142 - Project Area B"},{"_id":"66","name":"TRR 142 - Subproject B1"},{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - Subproject A2","_id":"59"}],"citation":{"mla":"Vondran, J., et al. “Spatially Asymmetric Transients of Propagating Exciton-Polariton Modes in a Planar CdZnTe/CdMgTe Guiding Structure.” <i>Physical Review B</i>, vol. 100, no. 15, 2019, p. 155308, doi:<a href=\"https://doi.org/10.1103/physrevb.100.155308\">10.1103/physrevb.100.155308</a>.","bibtex":"@article{Vondran_Spitzer_Bayer_Akimov_Trautmann_Reichelt_Meier_Weber_Meier_André_et al._2019, title={Spatially asymmetric transients of propagating exciton-polariton modes in a planar CdZnTe/CdMgTe guiding structure}, volume={100}, DOI={<a href=\"https://doi.org/10.1103/physrevb.100.155308\">10.1103/physrevb.100.155308</a>}, number={15}, journal={Physical Review B}, author={Vondran, J. and Spitzer, F. and Bayer, M. and Akimov, I.

Starting from the relaxed atomic geometries, we analyze the influence of self-energy corrections on the electronic band structure within the GW approximation. We find that quasiparticle shifts widen the direct (indirect) band gap by 1.21 (1.44), 1.58 (1.55), and 1.67 (1.64) eV for the cubic, tetragonal, and orthorhombic phase, respectively. By solving the Bethe-Salpeter equation, we obtain the linear dielectric function with excitonic and local-field effects, which turn out to be essential for good agreement with experimental data. From our results, we extract an exciton binding energy of 0.6, 0.5, and 0.5 eV for the cubic, tetragonal, and orthorhombic phase, respectively. Furthermore, we investigate the nonlinear second-harmonic generation (SHG) both theoretically and experimentally. The frequency-dependent second-order polarization tensor of orthorhombic KNbO3 is measured for incoming photon energies between 1.2 and 1.6 eV. In addition, calculations within the independent-(quasi)particle approximation are performed for the tetragonal and orthorhombic phase. The novel experimental data are in excellent agreement with the quasiparticle calculations and resolve persistent discrepancies between earlier experimental measurements and ab initio results reported in the literature."}],"file":[{"creator":"schindlm","description":"© 2019 American Physical Society","date_created":"2020-08-27T19:05:54Z","relation":"main_file","date_updated":"2020-08-30T14:34:33Z","file_name":"PhysRevMaterials.3.054401.pdf","file_size":1949504,"access_level":"open_access","title":"Quasiparticle and excitonic effects in the optical response of KNbO3","file_id":"18465","content_type":"application/pdf"}],"date_created":"2019-05-29T06:55:29Z","type":"journal_article","department":[{"_id":"295"},{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"170"},{"_id":"35"}]},{"publication_status":"published","date_updated":"2023-04-20T14:22:46Z","intvolume":"        99","year":"2019","title":"Excited-state band mapping and momentum-resolved ultrafast population dynamics in In/Si(111) nanowires investigated with XUV-based time- and angle-resolved photoemission spectroscopy","publication_identifier":{"issn":["2469-9950","2469-9969"]},"author":[{"last_name":"Nicholson","first_name":"C.

Within the independent-particle approximation an electronic transport gap of 2.97 eV is obtained that widens to about 5.23 eV when quasiparticle effects are included using the GW approximation. The optical response is shown to be strongly anisotropic due to (i) the slight asymmetry of the TiO6 octahedra in the (001) plane and (ii) their anisotropic distribution along the [001] and [100] directions. In addition, excitonic effects are very important: The solution of the Bethe–Salpeter equation indicates exciton binding energies of the order of 1.5 eV. Calculations that include both quasiparticle and excitonic effects are in good agreement with the measured reflectivity.","lang":"eng"}],"publication":"Journal of Physics: Materials","department":[{"_id":"296"},{"_id":"295"},{"_id":"230"},{"_id":"429"},{"_id":"170"},{"_id":"35"}],"type":"journal_article","date_created":"2019-09-19T14:34:16Z","file":[{"date_created":"2020-08-28T09:07:18Z","description":"Creative Commons Attribution 3.0 Unported Public License (CC BY 3.0)","creator":"schindlm","content_type":"application/pdf","file_id":"18535","title":"Potassium titanyl phosphate (KTP) quasiparticle energies and optical response","access_level":"open_access","file_size":1481174,"file_name":"Neufeld_2019_J._Phys._Mater._2_045003.pdf","date_updated":"2020-08-30T14:29:27Z","relation":"main_file"}]},{"publication_status":"published","date_updated":"2023-03-08T08:30:01Z","article_type":"original","year":"2019","title":"Anisotropic Water-Mediated Proton Conductivity in Large Iron(II) Metal–Organic Framework Single Crystals for Proton-Exchange Membrane Fuel Cells","status":"public","author":[{"first_name":"Hana","last_name":"Bunzen","full_name":"Bunzen, Hana"},{"full_name":"Javed, Ali","last_name":"Javed","first_name":"Ali"},{"full_name":"Klawinski, Danielle","last_name":"Klawinski","first_name":"Danielle"},{"full_name":"Lamp, Anton","first_name":"Anton","last_name":"Lamp"},{"first_name":"Maciej","last_name":"Grzywa","full_name":"Grzywa, Maciej"},{"first_name":"Andreas","last_name":"Kalytta-Mewes","full_name":"Kalytta-Mewes, Andreas"},{"full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann","id":"23547"},{"last_name":"von Nidda","first_name":"Hans-Albrecht Krug","full_name":"von Nidda, Hans-Albrecht Krug"},{"first_name":"Thorsten","last_name":"Wagner","full_name":"Wagner, Thorsten"},{"last_name":"Volkmer","first_name":"Dirk","full_name":"Volkmer, Dirk"}],"publication_identifier":{"issn":["2574-0970","2574-0970"]},"user_id":"23547","doi":"10.1021/acsanm.8b01902","page":"291-298","_id":"25908","language":[{"iso":"eng"}],"quality_controlled":"1","abstract":[{"text":"Herein we present a new proton-conducting iron(II) metal–organic framework (MOF) of an unusual structure formed by chains of alternating bistriazolate-p-benzoquinone anions and iron(II) cations with four axially coordinated water molecules. These chains assemble via π–π stacking between the aromatic units to form a three-dimensional grid-like network with channel pores filled with water molecules. The material was structurally characterized by single-crystal XRD analysis, and its water and thermal stability was investigated. The proton conductivity was studied by impedance measurements on needle-like single crystals. A simple but efficient measurement setup consisting of interdigital electrodes was used. The influence of the crystal orientation, temperature, and humidity was investigated. The iron(II)-MOF showed the highest proton conductivity of 3.3·10–3 S cm–1 at 22 °C and 94% relative humidity. Contrary to most known structures, the conductivity in this material is controlled by chemical properties of the pore system rather than by grain boundaries. The presented material is the starting point for further tailoring the proton-conducting properties, independent of morphological features which could find potential applications as membrane materials in proton-exchange membrane fuel cells.","lang":"eng"}],"publication":"ACS Applied Nano Materials","citation":{"ieee":"H.
