Their structures lead to characteristic low-angle XRD signatures. We introduce a model based on geometrical considerations to simulate CMK-8 and CMK-9 structures with variable volume fraction of carbon (vs. pore volume, i.e., variable 'pore wall thickness'). In addition, we also simulate carbon materials with variable amounts of guest species (e.g., sulfur) residing in their pores. The corresponding XRD patterns are calculated. The carbon volume fraction turns out to have a significant impact on the relative diffraction peak intensities, especially in case of CMK-9 carbon that features a bimodal porosity. Likewise, the presence of guest species in the pores may also strongly affect the relative peak intensities. Our study suggests that careful evaluation of experimental low-angle XRD patterns of (real) CMK-8 or CMK-9 materials offers an opportunity to obtain detailed information about the nanostructural properties in addition to the mere identification of the pore systems geometry."}]},{"abstract":[{"text":"A comparison of infrared spectroscopic analytical approaches was made in order to assess their applicability for internal structure characterization of SiO2 thin films. Markers for porosity and/or disorder based on the analysis of the asymmetric stretching absorption band of SiO2 between 900−1350 cm−1 were discussed. The shape of this band, which shows a well-defined LO–TO splitting, depends not only on the inherent characteristics of the film under analysis but also on the particular geometry of the IR experiment and the specific surface selection rules of the substrate. Three types of SiO2 thin films with clearly defined porosity ranging from dense films to mesoporous films were investigated by transmission (at different incidence angles), direct specular reflection (at different angles), and diffuse reflection. Two different types of substrate, metallic and semiconducting, were used. The combined effect of substrate and specific technique in the final shape of the band, was discussed, and the efficacy for their applicability to the determination of porosity in thin SiO2 films was critically evaluated.","lang":"eng"}],"quality_controlled":"1","citation":{"short":"T. de los Arcos, H.

However, the inherent surfacechemical properties of conventional materials, such as silica, carbon or organosilica, poses some limitations with respect to their application. Surface manipulation by functionalization with chemically more reactive groups is one way to improve materials for their desired purpose. Another approach is the design of high surface-area composite materials. The surface manipulation, either by functionalization or by introducing guest species, can be performed selectively. This means that when several distinct, i.e. , hierarchical, types of surfaces or pore systems exist in a material, each of them may be chosen for manipulation. Several strategies can be identified to achieve this goal. Molecules or molecule assemblies can be utilized to temporarily protect pores or surfaces (soft protection), while manipulation occurs at the accessible sites. This approach is a recurring motive in this review and can also be applied to rigid template matrices (hard protection). Furthermore, the size of functionalization agents (size protection) and their reactivity/diffusion (kinetic protection) into the pores can also be utilized to achieve selectivity. In addition, challenges in the synthesis and characterization of selectively manipulated ordered mesoporous materials are discussed.","lang":"eng"}],"publication":"Advanced Materials Interfaces","doi":"10.1002/admi.202001153","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202001153"}],"article_number":"2001153","article_type":"review","date_updated":"2023-03-07T10:45:40Z","publication_status":"published","publication_identifier":{"issn":["2196-7350","2196-7350"]},"author":[{"full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann","id":"23547"},{"id":"11848","first_name":"Christian","last_name":"Weinberger","full_name":"Weinberger, Christian"}],"year":"2021","title":"Selective Modification of Hierarchical Pores and Surfaces in Nanoporous Materials","oa":"1","quality_controlled":"1","citation":{"apa":"Tiemann, M., &#38; Weinberger, C.

First, two precursor formulations leading to the formation of iron oxide nanoparticles were used in a standardized SpraySyn burner system, and the final particle outcome was characterized by a broad range of established powder characterization techniques (TEM/HRTEM, SAXS, XRD, BET). The characterization of the powder products evidenced that mostly homogeneous gas-to-particle conversion takes place when applying an acidic precursor solution, whereas the absence of the acid leads to a dominant droplet-to-particle pathway. Our study indicates that a droplet-to-particle-pathway could be present even when processing the acidic formulation. However, even if a secondary pathway might take place in this case as well, it is not dominant and nearly negligible. Subsequently, the in situ particle structure evolution was investigated for the dominant gas-to-particle pathway, and particles were extracted along the flame axis for online SMPS and offline TEM/HRTEM analysis. Due to the highly reactive conditions within the flame (high temperatures, turbulent flow field, high particle number concentrations), the extraction of representative samples from spray flames is challenging. In order to handle the reactive conditions, two extraction techniques were tailored in this report. To extract an aerosol sample within the flame for SMPS measurement, a Hole in a Tube probe was adjusted. Thus, the mobility particle diameter as well as the corresponding distribution widths were obtained at different heights above the burner along the flame axis. For TEM/HRTEM image analysis, particle samples were collected thermophoretically by means of a tailored shutter system. Since all sampling grids were protected until reaching the flame axis and due to the low sampling time, momentary captures of local particle structures could be extracted precisely. The particle morphologies have clearly shown an evolution from spherical and paired particles in the flame center to fractal and compact agglomerates at later synthesis stages."}],"quality_controlled":"1","date_created":"2021-10-08T10:07:18Z","type":"journal_article","department":[{"_id":"9"},{"_id":"35"},{"_id":"2"},{"_id":"307"}]},{"citation":{"short":"J.A.

To potentiate this treatment, we have coated commercial glass plates with TiO2 nanoparticles prepared by the sol–gel method (TiO2-m), which exhibit a remarkable selectivity for the irreversible trapping of cancer cells. The physicochemical properties of the deposited TiO2-m nanoparticle coatings have been characterized by a number of complementary surface-analytical techniques and their interaction with leukemia and healthy blood cells were investigated. Scanning electron and atomic force microscopy verify the formation of a compact layer of TiO2-m nanoparticles. The particles are predominantly in the anatase phase and have hydroxyl-terminated surfaces as revealed by Raman, X-ray photoelectron, and infrared spectroscopy, as well as X-ray diffraction. We find that lymphoblastic leukemia cells adhere to the TiO2-m coating and undergo amoeboid-like migration, whereas lymphocytic cells show distinctly weaker interactions with the coating. This evidences the potential of this nanomaterial coating to selectively trap cancer cells and renders it a promising candidate for the development of future prototypes of PDT devices for the treatment of leukemia and other types of cancers with non-adherent cells.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1002/jbm.b.34862","year":"2021","title":"TiO2 nanoparticle coatings on glass surfaces for the selective trapping of leukemia cells from peripheral blood","author":[{"full_name":"Garcia Diosa, Jaime Andres","last_name":"Garcia Diosa","first_name":"Jaime Andres"},{"last_name":"Gonzalez Orive","first_name":"Alejandro","full_name":"Gonzalez Orive, Alejandro"},{"id":"11848","full_name":"Weinberger, Christian","last_name":"Weinberger","first_name":"Christian"},{"full_name":"Schwiderek, Sabrina","first_name":"Sabrina","last_name":"Schwiderek"},{"full_name":"Knust, Steffen","last_name":"Knust","first_name":"Steffen"},{"id":"23547","orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann","full_name":"Tiemann, Michael"},{"full_name":"Grundmeier, Guido","last_name":"Grundmeier","first_name":"Guido","id":"194"},{"id":"48864","full_name":"Keller, Adrian","orcid":"0000-0001-7139-3110","first_name":"Adrian","last_name":"Keller"},{"first_name":"Ruben Jesus","last_name":"Camargo Amado","full_name":"Camargo Amado, Ruben Jesus"}],"publication_identifier":{"issn":["1552-4973","1552-4981"]},"publication_status":"published","date_updated":"2023-03-08T08:10:25Z","article_type":"original","intvolume":"       109"},{"author":[{"first_name":"Felix","last_name":"Steinke","full_name":"Steinke, Felix"},{"last_name":"Javed","first_name":"Ali","full_name":"Javed, Ali"},{"full_name":"Wöhlbrandt, Stephan","last_name":"Wöhlbrandt","first_name":"Stephan"},{"id":"23547","full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael"},{"first_name":"Norbert","last_name":"Stock","full_name":"Stock, Norbert"}],"publication_identifier":{"issn":["1477-9226","1477-9234"]},"year":"2021","status":"public","title":"New isoreticular phosphonate MOFs based on a tetratopic linker","article_type":"original","date_updated":"2023-03-08T08:08:22Z","publication_status":"published","_id":"25892","language":[{"iso":"eng"}],"page":"13572-13579","doi":"10.1039/d1dt02610k","user_id":"23547","citation":{"ieee":"F.

Using a wide variety of spectroscopic, microscopic and thermal characterization methods, the chemical and morphological transition during oxidative stabilization (280 °C) and incipient carbonization (500 °C) was thoroughly investigated.

Here, we present a versatile template-assisted synthesis of nanostructured tin dioxide thin films using cellulose nanocrystals (CNCs). We demonstrate that the structural features of CNC-templated tin dioxide films strongly depend on the precursor composition. The precursor properties were studied by using low-temperature nuclear magnetic resonance spectroscopy of tin tetrachloride in solution. We demonstrate that it is possible to optimize the precursor conditions to obtain homogeneous precursor mixtures and therefore highly porous thin films with pore dimensions in the range of 10–20 nm (ABET = 46–64 m2 g–1, measured on powder). Finally, by exploiting the high surface area of the material, we developed a resistive gas sensor based on CNC-templated tin dioxide. The sensor shows high sensitivity to carbon monoxide (CO) in ppm concentrations and low cross-sensitivity to humidity. Most importantly, the sensing kinetics are remarkably fast; both the response to the analyte gas and the signal decay after gas exposure occur within a few seconds, faster than in standard SnO2-based CO sensors.

To achieve highly ordered inverse opal structures, one important issue during the colloidal crystal templating procedure is to form a stable precursor network before the template loses its structural integrity at high temperature. Using poly(methyl methacrylate), PMMA, colloidal crystal templates, it is essential to consider the physical and chemical changes of the precursors induced by the changes of PMMA during the thermal conversion. For a systematic investigation of this matter, we synthesized a variety of metal oxide inverse opals from the respective metal nitrates, including Cr2O3, Ga2O3, Fe2O3, In2O3, CuO, CeO2, and ZnO, to compare the effect of various modifications of precursors on the structural and optical properties. When the nitrate precursors have a lower thermal stability than the PMMA template, we have modified the metal nitrates by chelating or by polyacrylamide gelation to form more stable precursor networks."}],"publication":"European Journal of Inorganic Chemistry","doi":"10.1002/ejic.202000517","main_file_link":[{"url":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/ejic.202000517","open_access":"1"}],"language":[{"iso":"eng"}],"date_updated":"2023-03-08T08:24:24Z","publication_status":"published","article_type":"original","title":"Synthesis of Metal Oxide Inverse Opals from Metal Nitrates by PMMA Colloidal Crystal Templating","year":"2020","publication_identifier":{"issn":["1434-1948","1099-0682"]},"author":[{"first_name":"Xuyang","last_name":"Zhang","full_name":"Zhang, Xuyang"},{"full_name":"Weinberger, Christian","last_name":"Weinberger","first_name":"Christian","id":"11848"},{"last_name":"Amrehn","first_name":"Sabrina","full_name":"Amrehn, Sabrina"},{"last_name":"Wu","first_name":"Xia","full_name":"Wu, Xia"},{"id":"23547","full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael"},{"full_name":"Wagner, Thorsten","first_name":"Thorsten","last_name":"Wagner"}],"oa":"1","quality_controlled":"1","citation":{"apa":"Zhang, X., Weinberger, C., Amrehn, S., Wu, X., Tiemann, M., &#38; Wagner, T.

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.

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.

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.","lang":"eng"}],"publication":"Advanced Functional Materials"},{"date_updated":"2023-03-08T08:30:01Z","publication_status":"published","article_type":"original","title":"Anisotropic Water-Mediated Proton Conductivity in Large Iron(II) Metal–Organic Framework Single Crystals for Proton-Exchange Membrane Fuel Cells","status":"public","year":"2019","author":[{"first_name":"Hana","last_name":"Bunzen","full_name":"Bunzen, Hana"},{"full_name":"Javed, Ali","last_name":"Javed","first_name":"Ali"},{"last_name":"Klawinski","first_name":"Danielle","full_name":"Klawinski, Danielle"},{"last_name":"Lamp","first_name":"Anton","full_name":"Lamp, Anton"},{"first_name":"Maciej","last_name":"Grzywa","full_name":"Grzywa, Maciej"},{"full_name":"Kalytta-Mewes, Andreas","last_name":"Kalytta-Mewes","first_name":"Andreas"},{"last_name":"Tiemann","first_name":"Michael","orcid":"0000-0003-1711-2722","full_name":"Tiemann, Michael","id":"23547"},{"first_name":"Hans-Albrecht Krug","last_name":"von Nidda","full_name":"von Nidda, Hans-Albrecht Krug"},{"first_name":"Thorsten","last_name":"Wagner","full_name":"Wagner, Thorsten"},{"first_name":"Dirk","last_name":"Volkmer","full_name":"Volkmer, Dirk"}],"publication_identifier":{"issn":["2574-0970","2574-0970"]},"doi":"10.1021/acsanm.8b01902","user_id":"23547","page":"291-298","language":[{"iso":"eng"}],"_id":"25908","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.
