In the present study different dimensionless joining displacements are accounted for. The results show that high short-term tensile strength does not directly transfer to high long-term tensile strength. The morphology of the weld seam in the joined samples is examined by means of transmitted and reflected light microscopy. For the dimensionless joining displacements of 0.75 and 0.95, stretched spherulites are obtained. X-Ray diffraction can be used as a tool for qualitative and quantitative analysis and eventually for differentiation of samples of various joining displacements."}],"publication":"SPE ANTEC 2020: The Virtual Edition 5 ","type":"conference","title":"Long- and Short-Term Tensile Strength and Morphology of Joined Beta-Nucleated Polypropylene Parts","author":[{"id":"12504","full_name":"Wübbeke, Andrea","last_name":"Wübbeke","first_name":"Andrea"},{"first_name":"Volker","last_name":"Schöppner","full_name":"Schöppner, Volker"},{"full_name":"Paul, André","last_name":"Paul","first_name":"André"},{"last_name":"Tiemann","orcid":"0000-0003-1711-2722","full_name":"Tiemann, Michael","id":"23547","first_name":"Michael"},{"last_name":"Austermeier","full_name":"Austermeier, Laura","first_name":"Laura"},{"first_name":"Marcus","last_name":"Fitze","full_name":"Fitze, Marcus"},{"last_name":"Chen","full_name":"Chen, Mingie","first_name":"Mingie"},{"first_name":"Fabian","full_name":"Jakob, Fabian","last_name":"Jakob"},{"full_name":"Heim, Hans-Peter","last_name":"Heim","first_name":"Hans-Peter"},{"last_name":"Wu","full_name":"Wu, Tao","first_name":"Tao"},{"last_name":"Niendorf","full_name":"Niendorf, Thomas","first_name":"Thomas"},{"first_name":"Marie-Luise","full_name":"Röhricht, Marie-Luise","last_name":"Röhricht"},{"first_name":"Michael","last_name":"Schmidt","full_name":"Schmidt, Michael"}],"date_created":"2023-03-09T12:20:23Z","date_updated":"2023-05-05T10:03:33Z","citation":{"chicago":"Wübbeke, Andrea, Volker Schöppner, André Paul, Michael Tiemann, Laura Austermeier, Marcus Fitze, Mingie Chen, et al. “Long- and Short-Term Tensile Strength and Morphology of Joined Beta-Nucleated Polypropylene Parts.” In <i>SPE ANTEC 2020: The Virtual Edition 5 </i>, 2020.","ieee":"A.

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"}],"user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"_id":"25904","language":[{"iso":"eng"}],"article_type":"original","publication_status":"published","quality_controlled":"1","publication_identifier":{"issn":["1932-7447","1932-7455"]},"citation":{"ieee":"E.

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."}],"status":"public","publication":"Advanced Functional Materials","type":"journal_article","article_number":"1904505","article_type":"original","language":[{"iso":"eng"}],"_id":"25905","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547"},{"language":[{"iso":"eng"}],"article_type":"original","user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"_id":"25908","status":"public","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"}],"type":"journal_article","publication":"ACS Applied Nano Materials","doi":"10.1021/acsanm.8b01902","title":"Anisotropic Water-Mediated Proton Conductivity in Large Iron(II) Metal–Organic Framework Single Crystals for Proton-Exchange Membrane Fuel Cells","date_created":"2021-10-08T10:46:06Z","author":[{"first_name":"Hana","last_name":"Bunzen","full_name":"Bunzen, Hana"},{"last_name":"Javed","full_name":"Javed, Ali","first_name":"Ali"},{"first_name":"Danielle","last_name":"Klawinski","full_name":"Klawinski, Danielle"},{"last_name":"Lamp","full_name":"Lamp, Anton","first_name":"Anton"},{"last_name":"Grzywa","full_name":"Grzywa, Maciej","first_name":"Maciej"},{"first_name":"Andreas","last_name":"Kalytta-Mewes","full_name":"Kalytta-Mewes, Andreas"},{"orcid":"0000-0003-1711-2722","last_name":"Tiemann","full_name":"Tiemann, Michael","id":"23547","first_name":"Michael"},{"first_name":"Hans-Albrecht Krug","full_name":"von Nidda, Hans-Albrecht Krug","last_name":"von Nidda"},{"first_name":"Thorsten","full_name":"Wagner, Thorsten","last_name":"Wagner"},{"full_name":"Volkmer, Dirk","last_name":"Volkmer","first_name":"Dirk"}],"date_updated":"2023-03-08T08:30:01Z","citation":{"mla":"Bunzen, Hana, et al. “Anisotropic Water-Mediated Proton Conductivity in Large Iron(II) Metal–Organic Framework Single Crystals for Proton-Exchange Membrane Fuel Cells.” <i>ACS Applied Nano Materials</i>, 2019, pp. 291–98, doi:<a href=\"https://doi.org/10.1021/acsanm.8b01902\">10.1021/acsanm.8b01902</a>.","bibtex":"@article{Bunzen_Javed_Klawinski_Lamp_Grzywa_Kalytta-Mewes_Tiemann_von Nidda_Wagner_Volkmer_2019, title={Anisotropic Water-Mediated Proton Conductivity in Large Iron(II) Metal–Organic Framework Single Crystals for Proton-Exchange Membrane Fuel Cells}, DOI={<a href=\"https://doi.org/10.1021/acsanm.8b01902\">10.1021/acsanm.8b01902</a>}, journal={ACS Applied Nano Materials}, author={Bunzen, Hana and Javed, Ali and Klawinski, Danielle and Lamp, Anton and Grzywa, Maciej and Kalytta-Mewes, Andreas and Tiemann, Michael and von Nidda, Hans-Albrecht Krug and Wagner, Thorsten and Volkmer, Dirk}, year={2019}, pages={291–298} }","short":"H.

X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) reflection absorption spectroscopy confirmed the monolayer formation. Water adsorption isotherms were studied by a combination of in-situ FTIR reflection spectroscopy and quartz crystal microbalance (QCM) while macroscopic wetting was analysed by contact angle measurements. The comparative data evaluation indicates that the macroscopic wetting behaviour was changed as expected, however, that water nanodroplets formed both at intrinsic defects of the FOTS monolayer and at the FOTS/SiOx interface. Capillary bridges of liquid water are dominantly formed in the confined particle contact areas and between surface asperities on the particles. The comparison of wetting, adsorption and capillary bridge formation shows that the hydrophobization of porous materials by organosilane monolayers leads to the formation of morphology dependent nanoscopic defects that act as sites for preferential capillary bridge formation."}],"status":"public","publication":"Applied Surface Science","type":"journal_article","language":[{"iso":"eng"}],"_id":"22541","department":[{"_id":"302"}],"user_id":"54863","year":"2019","page":"873-879","citation":{"apa":"Giner, I., Torun, B., Han, Y., Duderija, B., Meinderink, D., Orive, A.

The selective filling has a drastic impact on the low-angle X-ray diffraction pattern of this novel class of materials. The structures of CMK-5, CMK-5 composite materials (sulfur and SnO2 as guest species), and CMK-3 carbon were simulated to investigate the influence of the pore filling with different guest species on the diffraction pattern and compared with experimental results. Additionally, the impact of structural defects is taken into account. The nature of the guest species strongly influences the relative intensity of the diffraction peaks. It turns out that the diffraction patterns of sulfur-carbon composite materials are nearly identical as those of CMK-3 carbon, which is attributed to a similar electron density of carbon and sulfur. Thus, sulfur is an ideal guest species to investigate the selective pore filling in CMK-5 carbon.","lang":"eng"}],"publication":"Microporous and Mesoporous Materials","type":"journal_article","language":[{"iso":"eng"}],"article_type":"original","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547","_id":"25912","page":"24-31","citation":{"chicago":"Weinberger, Christian, Marc Hartmann, Sai Ren, Thomas Sandberg, Jan-Henrik Smått, and Michael Tiemann. “Selective Pore Filling of Mesoporous CMK-5 Carbon Studied by XRD: Comparison between Theoretical Simulations and Experimental Results.” <i>Microporous and Mesoporous Materials</i>, 2018, 24–31. <a href=\"https://doi.org/10.1016/j.micromeso.2018.02.035\">https://doi.org/10.1016/j.micromeso.2018.02.035</a>.","ieee":"C.

Especially the specific surface area of reduced graphene oxide was selectively influenced by controlled drying of the material. The different types of reduced graphene oxide particles were used to produce epoxy-amine composites that significantly change their curing behaviour and mechanical properties. A variety of surface areas and compositions were prepared by combination of a fast heating rate and different drying methods. The combination of freeze drying with a fast heating rate leads to a large specific surface area of 680 m2/g. The morphologies of the particles were observed by scanning electron microscope and the BET surface area was measured with nitrogen-physisorption. The exfoliation quality was measured by XRD. The generated graphene oxide and thermally reduced graphene oxide particles were mixed with epoxy-amine resin. The curing behaviour was studied with rheological and differential scanning calorimetry (DSC) measurements. We observed that different surface functionalities lowers the Glass transition temperature and the gel time of an epoxy-amine curing system. In addition, we found that generated graphene oxide acts as flexibilizer. An increase of the deformation from 2.5 mm to 3.1 mm was measured by Erichsen Cupping Test."}],"status":"public"},{"title":"Kinetics of ozone decomposition in porous In2O3 monoliths","doi":"10.1039/c6cp08874k","date_updated":"2023-01-24T07:38:08Z","date_created":"2021-10-08T11:07:31Z","author":[{"full_name":"Klawinski, Danielle","last_name":"Klawinski","first_name":"Danielle"},{"first_name":"Christian","id":"11848","full_name":"Weinberger, Christian","last_name":"Weinberger"},{"last_name":"Klaus","full_name":"Klaus, Dominik","first_name":"Dominik"},{"first_name":"Jan-Henrik","full_name":"Smått, Jan-Henrik","last_name":"Smått"},{"first_name":"Michael","id":"23547","full_name":"Tiemann, Michael","last_name":"Tiemann","orcid":"0000-0003-1711-2722"},{"first_name":"Thorsten","last_name":"Wagner","full_name":"Wagner, Thorsten"}],"year":"2017","page":"10326-10332","citation":{"chicago":"Klawinski, Danielle, Christian Weinberger, Dominik Klaus, Jan-Henrik Smått, Michael Tiemann, and Thorsten Wagner. “Kinetics of Ozone Decomposition in Porous In2O3 Monoliths.” <i>Physical Chemistry Chemical Physics</i>, 2017, 10326–32. <a href=\"https://doi.org/10.1039/c6cp08874k\">https://doi.org/10.1039/c6cp08874k</a>.","ieee":"D.
