  text: It is possible to infiltrate a guest species selectively in one pore system
    of bimodal mesoporous CMK-5 carbon by an optimized nanocasting procedure. 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.

  text: We describe the synthesis of mesoporous Al2O3 and MgO layers on silicon wafer
    substrates by using poly(dimethylacrylamide) hydrogels as porogenic matrices.
    Hydrogel films are prepared by spreading the polymer through spin-coating, followed
    by photo-cross-linking and anchoring to the substrate surface. 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. Materials are characterized by SEM, FIB ablation, EDX,
    and Kr physisorption porosimetry.

  text: Ordered mesoporous CMK-5 carbon exhibits two distinct pore systems that can
    be modified individually. 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.

  text: Organic polymer-hydrogels are known to be capable of directing the nucleation
    and growth of inorganic materials, such as silica, metal oxides, apatite or metal
    chalcogenides. 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. This micro-review provides a survey of select examples from the literature.

  text: Different types of reduced graphene oxide and graphene oxide particles have
    been studied regarding their influence on the curing behaviour of epoxy-amine
    resins. 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.

  text: Dimethylacrylamide-based hydrogels were utilized as porogenic matrices in
    the synthesis of mesoporous aluminum oxide (γ-Al2O3) with specific BET surface
    areas up to 360 m2 g–1. Polymers with molecular mass in the range 12000–35000
    g mol–1 were synthesized from dimethylacrylamide and various comonomers by free-radical
    polymerization. Photo-cross-linking of the polymers and impregnation with aluminum
    nitrate [Al(NO3)3] was carried out in a single step, followed by formation of
    Al(OH)3/AlO(OH) and subsequent calcination. Calcination led to the formation of
    mesoporous Al2O3 and simultaneous combustion of the hydrogel. The structural properties
    of the products were characterized by powder XRD, N2 physisorption analysis, Hg
    intrusion porosimetry, and thermogravimetric analysis.

  text: The sorption properties of mixed-linker CAU-10 type metal organic frameworks
    (MOFs), [Al(OH)(1,3-BDC-X)n(1,3-BDC-SO3H)m] with 1,3-BDC = 1,3-benzenedicarboxyliate,
    X = H, NO2 or OH, 0.76 ≤ n ≤ 0.89 and 0.11 ≤ m ≤ 0.24, can be varied by surface
    modification through variation of the respective linker molecules. It is thus
    possible to design surface-modified CAU-10 type MOFs with variable affinity and
    accessibility of the pores for water vapour. When used as a dielectric in a capacitor,
    the MOF material will change its permittivity depending on the amount of physisorbed
    water; this is the working principle of capacitive humidity sensors. Three different
    mixed-linker compounds with CAU-10 structure are compared regarding their water
    sorption and impedance characteristics. A setup was developed allowing the characterization
    of the MOF samples under exposure to different relative humidity values in air
    by impedance spectroscopy. Interpretation of the results by means of standard
    models shows that the MOFs are qualified for functional layers of capacitive humidity
    sensors. Since the prepared MOFs are more temperature-stable than many commonly
    used polymers they offer the potential to build a new generation of high-temperature
    (up to 350 °C) humidity sensors.

  text: Ordered, bimodal mesoporous CMK-5 carbon is prepared by using mesoporous SBA-15
    silica as a structural mold. The carbon material is chemically modified by oxidative
    treatment with acidic persulfate solution. This leads to the creation of oxygen-containing
    functionalities at the pore walls of the carbon (up to 13 wt% oxygen), as confirmed
    by IR spectroscopy. The oxidative treatment is carried out before removal of the
    silica mold which ensures that only one of the two distinct modes of mesopores
    (namely, the intra-tubular pores) is affected; the other mode (inter-tubular pores)
    is protected from oxidation by the presence of the silica mold. This is proven
    by water vapor physisorption analysis. The oxidatively treated (intra-tubular)
    pores are significantly more polar and, hence, better wettable than the untreated
    (inter-tubular) pores.

  text: Characterization and application of (meso)porous materials often require information
    about the density of the respective samples. For example, the BET surface area
    is, by definition, normalized to the sample mass; hence, any comparison between
    samples of different composition needs to take into account their respective densities.
    Literature data on the densities of porous materials are scarce. Frequently, only
    bulk-phase densities are available which sometimes differ from those of porous
    samples, especially for amorphous systems, such as silica or carbon. The apparent
    density, i.e. the density of the sample excluding the gas-accessible pore volume,
    is typically determined by helium gas pycnometry utilizing specialized pycnometers.
    We demonstrate how to obtain the same data from standard N2 physisorption measurements
    as part of the regular measurement routine. We evaluate the method by reference
    measurements utilizing a non-porous reference sample (glass rod) to confirm the
    validity of the method. Then we present results on apparent density measurements
    of several mesoporous silica materials (MCM-41, MCM-48, SBA-15, KIT-6), mesoporous
    carbon (CMK-3, -5, -8, -9), and a variety of mesoporous metal oxides obtained
    by nanocasting.

  text: Metal–organic frameworks (MOFs) are crystalline microporous materials with
    tunable chemical and physical properties. By combining various metal clusters
    with different interconnecting organic linkers, the pore structure, crystallinity,
    as well as the surface properties can be modified. In the present work, modification
    of the organic linker molecules is utilized to synthesize CAU-10 type MOFs with
    variable affinity of the pore surface to water. In principle, this should influence
    the accessibility of the pores for water vapor and therefore offer a tool to control
    its sorption properties. For a deeper understanding we studied the water sorption
    characteristics and compared the results to the conductive and dielectric properties
    studied by impedance spectroscopy. Spectra in a wide frequency range from 1 mHz
    to 1 MHz were recorded. Data analysis is performed using the Havriliak–Negami
    model. The MOFs are also tested as sensitive layers for capacitive humidity sensing
    by correlating the change in permittivity of the materials with the amount of
    physisorbed water. Such an MOF-based sensor was tested with respect to environmental
    monitoring and compared to a commonly used commercial humidity sensor.

  text: A variety of metal nitrates were filled into the pores of an ordered mesoporous
    CMK-3 carbon matrix by solution-based impregnation. Thermal conversion of the
    metal nitrates into the respective metal oxides, and subsequent removal of the
    carbon matrix by thermal combustion, provides a versatile means to prepare mesoporous
    metal oxides (so-called nanocasting). This study aims to monitor the thermally
    induced processes by thermogravimetric analysis (TGA), coupled with mass ion detection
    (MS). The highly dispersed metal nitrates in the pores of the carbon matrix tend
    to react to the respective metal oxides at lower temperature than reported in
    the literature for pure, i.e., carbon-free, metal nitrates. The subsequent thermal
    combustion of the CMK-3 carbon matrix also occurs at lower temperature, which
    is explained by a catalytic effect of the metal oxides present in the pores. This
    catalytic effect is particularly strong for oxides of redox active metals, such
    as transition group VII and VIII metals (Mn, Fe, Co, Ni), Cu, and Ce.

  text: Ordered mesoporous In2O3 particles of variable size synthesized by the nanocasting
    method are used for preparation of resistive gas-sensing layers. Light activation
    by a LED (blue light, 460 nm) permits room-temperature ozone sensing. Apart from
    differences in base-line resistance in sensing layers containing small (diameter
    approx. 170 nm) or large particles (approx. 870 nm), differences in the response
    amplitude and response time constant are also observed. Signal stabilization is
    achieved faster for small particles. In addition, sensors show a particle size-dependent
    reaction threshold for low ozone concentration. Larger particles show negligible
    response to 50 ppb ozone whereas a significant response is observed for the small-particle
    sensors. A simple model based on geometrical properties and formation of depletion
    layers explaining the observed behavior is presented.

  text: Cobalt oxide spinel (Co3O4) with an ordered nanostructure is used as a resistive
    gas sensor for carbon monoxide (CO) in low ppm concentrations. The operating temperature
    has a strong impact on the concentration-dependent sensing behavior. At lower
    temperature (473 K) the sensor response is governed mainly by surface coverage
    with CO and/or CO2, whereas at higher temperature (563 K) oxygen diffusion in
    the crystal lattice of Co3O4 strongly affects the sensing behavior.

  text: Catalysis plays a central role in many fields of life, e.g., in biochemical
    processes, to reduce energy costs and resources in chemical industry and to decrease
    or even avoid environmental pollution and in energy management. Porous alumina
    (Al2O3) is an essential material in various applications, especially as a support
    material for catalysts. It is often prepared by nanocasting using porous carbon
    materials that serve as rigid structure matrices. In this work, an alternative
    way to synthesize mesoporous Al2O3 by using hydrogels as porogenic material is
    presented. Hydrogels can easily be patterned by light and used to imprint their
    structure onto alumina opening a new approach to fabricate patterned Al2O3. The
    hydrogels used in this work are based on poly(dimethylacrylamide) and were photo-chemically
    cross-linked. Followed by a nanocasting process, mesoporous alumina samples were
    synthesized and characterized by N2 physisorption and X-ray diffraction. The cross-linker
    amount in the polymer network was varied and the influence on the properties of
    the Al2O3 is analyzed.

  text: The synthesis of a periodically ordered, nanostructured composite consisting
    of CoFe2O4 and BaTiO3 is presented. In a first step, mesoporous CoFe2O4 is prepared
    by the structure replication method (nanocasting) using mesoporous KIT-6 silica
    as a structural mold. Subsequently, BaTiO3 is created inside the pores of CoFe2O4
    by the citrate route, resulting in a well-ordered composite material of both phases.
    The two components are known for their distinct ferroic properties, namely ferrimagnetism
    (CoFe2O4) and ferroelectricity (BaTiO3), respectively. Therefore, this proof of
    synthesis concept offers new perspectives in the fabrication of composite materials
    with multiferroic properties.

  text: Ordered mesoporous silica phases (e.g. KIT-6, SBA-15) are used as structure
    matrices for negative replica structures of mesoporous In2O3. We present a detailed
    study on how the controlled synthesis of mono-, bi- and trimodal pore systems
    in the products is accomplished by systematic variation of the procedure of infiltrating
    a precursor species (In(NO3)3) into the pores of the silica matrix and subsequent
    thermal conversion into In2O3. Melt impregnation and conversion in a closed reactor
    facilitates a one-step casting process for ordered mesoporous indium oxide (In2O3).
    We present a model based on variation of the pore filling.

  text: Recently indium oxide (In2O3) attracted attention as a material for sensing
    layers in semiconducting gas sensors. Compared to frequently investigated materials
    like tin dioxide (SnO2), tungsten trioxide (WO3), or gallium oxide (Ga2O3) indium
    oxide offers some unique properties. The most prominent one is its selectivity
    to oxidizing gases such as ozone (O3) or nitrogen dioxide (NO2) at low operating
    temperatures (<150°C). Combined with the photoreduction properties of nanocast,
    porous In2O3 highly selective sensing layers with a fast response can be prepared.
    In some cases even room temperature measurements are possible; therefore this
    material allows for designing low-power sensors without the need for special sensor
    substrates (e.g., μ-hotplates). Detailed analysis of the sensing mechanism reveals
    that known sensing models are not able to describe the observed effects. Therefore
    a new sensing model for ordered nanoporous In2O3 is presented which will be applicable
    for nonstructured material too.

  text: In this paper, the development and validation of a shield prototype for resistive
    sensor array characterization with Arduino UNO, a platform based on ATmega328
    microcontroller provided by ATMEL, is reported. The resistance variation of the
    sensor can be evaluated by properly choosing the capacitance value and by measuring
    the period (frequency) of a custom inverter-based oscillator. The GUI and the
    developed firmware are able to perform the real-time monitoring of the sensor
    responses. The developed shield is able to measure the response of up to six sensors
    under UV radiation by means of LED devices. First results carried out with resistive
    sensors based on mesoporous In2O3-based material under UV light exposure are reported.
