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. author: - first_name: Andrea full_name: Wübbeke, Andrea id: '12504' last_name: Wübbeke - first_name: Volker full_name: Schöppner, Volker last_name: Schöppner - first_name: André full_name: Paul, André last_name: Paul - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Laura full_name: Austermeier, Laura last_name: Austermeier - first_name: Marcus full_name: Fitze, Marcus last_name: Fitze - first_name: Mingie full_name: Chen, Mingie last_name: Chen - first_name: Fabian full_name: Jakob, Fabian last_name: Jakob - first_name: Hans-Peter full_name: Heim, Hans-Peter last_name: Heim - first_name: Tao full_name: Wu, Tao last_name: Wu - first_name: Thomas full_name: Niendorf, Thomas last_name: Niendorf - first_name: Marie-Luise full_name: Röhricht, Marie-Luise last_name: Röhricht - first_name: Michael full_name: Schmidt, Michael last_name: Schmidt citation: ama: 'Wübbeke A, Schöppner V, Paul A, et al.

The materials possess fine-leaved structures at their particle surface (nanowall hollow micro spheres). Morphology control is achieved by citric acid used as an additive in variable relative quantities during the synthesis. The structure formation is studied by various time-dependent ex situ methods, such as scanning electron microscopy, x-ray diffraction, and Raman spectroscopy. The fine-leaved surface structure is characterized by high-resolution transmission electron microscopy techniques (HRTEM, STEM), using a high-angle annular dark field detector, as well as by differential phase contrast analysis. In-depth structural characterization of the nanowalls by drop-by-drop ex situ FE-SEM analysis provides insight into possible structure formation mechanisms. Further investigation addresses the thermal stability of the particle morphology and the enhancement of the surface-to-volume ratio by heat treatment (examined by N2 physisorption). article_type: original author: - first_name: Katja full_name: Engelkemeier, Katja id: '21743' last_name: Engelkemeier - first_name: Jörg full_name: Lindner, Jörg id: '20797' last_name: Lindner - first_name: Julius full_name: Bürger, Julius id: '46952' last_name: Bürger - first_name: Kathrin full_name: Vaupel, Kathrin last_name: Vaupel - first_name: Marc full_name: Hartmann, Marc last_name: Hartmann - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Engelkemeier K, Lindner J, Bürger J, et al.

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. Due to the high surface area of the mesoporous silicas, a possible catalytic application based on immobilization of an organocatalyst for an asymmetric aldol reaction is discussed. article_number: '249' article_type: original author: - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Tatjana full_name: Heckel, Tatjana last_name: Heckel - first_name: Patrick full_name: Schnippering, Patrick last_name: Schnippering - first_name: Markus full_name: Schmitz, Markus last_name: Schmitz - first_name: Anpeng full_name: Guo, Anpeng last_name: Guo - first_name: Waldemar full_name: Keil, Waldemar last_name: Keil - first_name: Heinrich C. full_name: Marsmann, Heinrich C. last_name: Marsmann - first_name: Claudia full_name: Schmidt, Claudia id: '466' last_name: Schmidt orcid: 0000-0003-3179-9997 - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: René full_name: Wilhelm, René last_name: Wilhelm citation: ama: Weinberger C, Heckel T, Schnippering P, et al.

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. article_type: original author: - first_name: Evelyn full_name: Jantsch, Evelyn last_name: Jantsch - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Thomas full_name: Koop, Thomas last_name: Koop citation: ama: Jantsch E, Weinberger C, Tiemann M, Koop T.

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. article_number: '1904505' article_type: original author: - first_name: Andrej full_name: Paul, Andrej last_name: Paul - first_name: Bertram full_name: Schwind, Bertram last_name: Schwind - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Thorsten full_name: Wagner, Thorsten last_name: Wagner citation: ama: 'Paul A, Schwind B, Weinberger C, Tiemann M, Wagner T.

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. article_type: original author: - first_name: Hana full_name: Bunzen, Hana last_name: Bunzen - first_name: Ali full_name: Javed, Ali last_name: Javed - first_name: Danielle full_name: Klawinski, Danielle last_name: Klawinski - first_name: Anton full_name: Lamp, Anton last_name: Lamp - first_name: Maciej full_name: Grzywa, Maciej last_name: Grzywa - first_name: Andreas full_name: Kalytta-Mewes, Andreas last_name: Kalytta-Mewes - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - 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 - first_name: Dirk full_name: Volkmer, Dirk last_name: Volkmer citation: ama: Bunzen H, Javed A, Klawinski D, et al.

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. author: - first_name: Ignacio full_name: Giner, Ignacio last_name: Giner - first_name: Boray full_name: Torun, Boray last_name: Torun - first_name: Yan full_name: Han, Yan last_name: Han - first_name: Belma full_name: Duderija, Belma id: '54863' last_name: Duderija - first_name: Dennis full_name: Meinderink, Dennis last_name: Meinderink - first_name: Alejandro González full_name: Orive, Alejandro González last_name: Orive - first_name: Maria Teresa full_name: de los Arcos de Pedro, Maria Teresa id: '54556' last_name: de los Arcos de Pedro - first_name: Christian full_name: Weinberger, Christian last_name: Weinberger - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier citation: ama: Giner I, Torun B, Han Y, et al.

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. article_type: original author: - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Marc full_name: Hartmann, Marc last_name: Hartmann - first_name: Sai full_name: Ren, Sai last_name: Ren - first_name: Thomas full_name: Sandberg, Thomas last_name: Sandberg - first_name: Jan-Henrik full_name: Smått, Jan-Henrik last_name: Smått - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 citation: ama: 'Weinberger C, Hartmann M, Ren S, Sandberg T, Smått J-H, Tiemann M.

The metal oxides are obtained by swelling the hydrogels in the respective metal nitrate solutions and subsequent thermal conversion. Combustion of the hydrogel results in mesoporous metal oxide layers with thicknesses in the μm range and high specific surface areas up to 558 m2∙g−1.

This work demonstrates how one of the pore systems can be selectively filled with elemental sulfur, while the other pore system remains empty. The resulting sulfur–carbon composite material with high residual porosity can be used as the cathode material in lithium–sulfur battery cells. We present a systematic investigation of the loading of CMK-5 carbon with variable relative amounts of sulfur and compare the results to the preparation of SnO2 (as well as TiO2, Mn2O3/Mn3O4, NiO) nanoparticle-loaded CMK-5 carbon. article_type: original author: - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Sai full_name: Ren, Sai last_name: Ren - first_name: Marc full_name: Hartmann, Marc last_name: Hartmann - first_name: Thorsten full_name: Wagner, Thorsten last_name: Wagner - first_name: Didem.

This approach can be exploited in the synthesis of materials that exhibit defined nanoporosity. When the organic polymer-based hydrogel is incorporated in the inorganic product, a composite is formed from which the organic component may be selectively removed, yielding nanopores in the inorganic product. Such porogenic impact resembles the concept of using soft or hard templates for porous materials.

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. article_type: original author: - first_name: Andreas full_name: Wolk, Andreas last_name: Wolk - first_name: Marta full_name: Rosenthal, Marta last_name: Rosenthal - first_name: Julia full_name: Weiß, Julia last_name: Weiß - first_name: Markus full_name: Voigt, Markus id: '15182' last_name: Voigt - first_name: Jan-Niklas full_name: Wesendahl, Jan-Niklas last_name: Wesendahl - first_name: Marc full_name: Hartmann, Marc last_name: Hartmann - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Rene full_name: Wilhelm, Rene last_name: Wilhelm - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Wolfgang full_name: Bremser, Wolfgang id: '32' last_name: Bremser citation: ama: Wolk A, Rosenthal M, Weiß J, et al.
