  text: Novel oxalate-bridged heterotrinuclear complexes [A][Mn2Cr(bpy)2(H2O)2Cl2(C2O4)3]
    (A = (CH3)2(C2H5)NH+ (1) and (CH3)(C2H5)2NH+ (2); bpy = 2,2′-bipyridine) were
    synthesized using an aqueous solution of [A]3[Cr(C2O4)3] as a building block in
    reaction with Mn2+ ions and with the addition of the N-donor ligand bipyridine.
    The isostructural heterometallic complex salts were characterized by single-crystal
    and powder X-ray diffraction, infrared and impedance spectroscopy, thermal analysis
    and magnetization measurements. The trinuclear anion [{Mn(bpy)(H2O)Cl(μ-C2O4)}2Cr(C2O4)]−
    consists of two [Mn(bpy)(H2O)Cl]+ units bridged by the [Cr(C2O4)3]3− anion, which
    acts as a bidentate ligand towards each of the manganese atoms. The anions are
    hydrogen bonded to each other via coordinated chloride anions, water molecules
    and oxygen oxalate atoms, resulting in two-dimensional (2D) hydrogen bonding layers.
    Compounds exhibit water-assisted proton conductivity behaviour, which was investigated
    at different temperatures and relative humidities (RH). At 25 °C, an increase
    in RH from 60% to 93% resulted in an obvious proton conducting switch from 9.1
    × 10−11 to 5.6 × 10−5 S cm−1 for 1 and from 7.4 × 10−10 to 1.8 × 10−6 S cm−1 for
    2, corresponding to high on/off ratios of about 106 for 1 and 104 for 2. In situ
    powder X-ray diffraction (PXRD) analysis showed that unit cell parameters of compounds
    1 and 2 slightly increase when exposed to humid conditions. This confirmed that
    incorporation of water molecules into structures with pores and voids causes the
    proton conductivity switching phenomenon. Magnetic susceptibility measurements
    indicate a ferromagnetic interaction between Cr3+ and Mn2+ ions bridged by the
    bis(bidentate) oxalate group. The prepared compounds 1 and 2 were explored as
    single-source precursors for the formation of spinel oxide by their thermal treatment.
    With increasing temperature, the spinel composition changed according to the formula
    Mn1+xCr2–xO4 (0 ≤ x ≤ 1), where x = 0.7 at 500 °C and x = 1 at 900 °C when tet[MnII]oct[MnIIICrIII]O4
    is formed. The (micro)structure, morphology, and optical properties of spinel
    Mn2CrO4 were characterized by PXRD, scanning electron microscopy and UV-Vis diffuse
    reflectance spectroscopy. The photocatalytic activity of this oxide in degradation
    of the methylene blue dye under Vis irradiation without and with the support of
    hydrogen peroxide was further investigated.

  text: The increasing demand for advanced sensing technologies drives the development
    of chemical sensors using innovative materials. In gas sensing, optical sensors
    are often used to detect gases such as CO, NOx, and O2. Oxygen sensors typically
    incorporate dyes into oxygen-permeable matrices like polymers, silica, or zeolites.
    Alternatively, semiconductor surface chemistry can enable O2 detection. However,
    these approaches are often limited by slow response and recovery times and low
    selectivity, restricting their practical applications. The metal-organic framework
    MOF-76(Eu) and its yttrium-modified variant, MOF-76(Eu/Y) are reported to exhibit
    highly reversible and fast optical responses to varying O2 concentrations. Time-resolved
    emission measurements are performed over short (seconds) and long (hours) timescales
    using N2 and synthetic air mixtures. Cross-sensitivity to humidity is analyzed.
    Multichannel scaling photon-counting experiments confirm quenching at the linker
    level, as the emission lifetime remains nearly constant. Yttrium significantly
    improves stability and performance at room temperature. Structural and optical
    changes induced by yttrium are investigated. Additionally, MIL-78(Eu), another
    Eu-BTC-based MOF with a different coordination environment, is synthesized. Unlike
    MOF-76(Eu), MIL-78(Eu) exhibits distinct optical properties but lacks a reversible
    response to O2. These results highlight the potential of MOF-76-based materials
    for high-performance O2 sensing.

  text: Due to the hydrolytic instability of LiPF6 in carbonate-based solvents, HF
    is a typical impurity in Li-ion battery electrolytes. HF significantly influences
    the performance of Li-ion batteries, for example by impacting the formation of
    the solid electrolyte interphase at the anode and by affecting transition metal
    dissolution at the cathode. Additionally, HF complicates studying fundamental
    interfacial electrochemistry of Li-ion battery electrolytes, such as direct anion
    reduction, because it is electrocatalytically relatively unstable, resulting in
    LiF passivation layers. Methods to selectively remove ppm levels of HF from LiPF6-containing
    carbonate-based electrolytes are limited. We introduce and benchmark a simple
    yet efficient electrochemical in situ method to selectively remove ppm amounts
    of HF from LiPF6-containing carbonate-based electrolytes. The basic idea is the
    application of a suitable potential to a high surface-area metallic electrode
    upon which only HF reacts (electrocatalytically) while all other electrolyte components
    are unaffected under the respective conditions.

  text: Leaky mode resonances of the setae of Cataglyphis bombycina are found to enhance
    the thermal emission of the animals by near field coupling to the chitinous exoskeleton.
    This is remarkable, as the setae are also an adaption to enhance the reflectivity
    in the visible wavelength range. Both effects are dependent on morphology, dimensions
    and spatial arrangement. These parameters were experimentally characterized and
    simulated by finite difference time domain simulations to elucidate the optical
    impact of the setae in the mid infrared range and the contribution of leaky mode
    resonances. This mode of action and the setae’s optical properties in the visible
    range explain evolutionary strains that led to the actual morphology and size
    of the setae.

  text: In dieser Arbeit werden Untersuchungen zur sauerstoffabhängigen Photolumineszenz
    von Zink-Zinn-Oxid-Partikeln präsentiert, welche perspektivisch für die optische
    Sauerstoffdetektion eingesetzt werden sollen. Zink-Zinn-Oxid zeigt eine sauerstoffabhängige
    Photolumineszenz im sichtbaren Spektralbereich und wird hier als eine photostabile
    Alternative zu den kommerziell verfügbaren metallorganischen Verbindungen vorgestellt.
    Der Fokus liegt dabei auf dem Einfluss der Temperatur auf die Sauerstoffsensitivität
    der Photolumineszenz. Wir zeigen, dass bereits leichte Temperaturerhöhungen zu
    einer signifikanten Verbesserung der Sauerstoffsensitivität der Photolumineszenz
    führen und gleichzeitig die Signalqualität erhöhen.

  text: <jats:p>Pore engineering is commonly used to alter the properties of metal–organic
    frameworks. This is achieved by incorporating different linker molecules (L) into
    the structure, generating isoreticular frameworks. CPO-27, also named MOF-74,
    is a prototypical material for this approach, offering the potential to modify
    the size of its one-dimensional pore channels and the hydrophobicity of pore walls
    using various linker ligands during synthesis. Thermal activation of these materials
    yields accessible open metal sites (i.e., under-coordinated metal centers) at
    the pore walls, thus acting as strong primary binding sites for guest molecules,
    including water. We study the effect of the pore size and linker hydrophobicity
    within a series of Ni2+-based isoreticular frameworks (i.e., Ni2L, L = dhtp, dhip,
    dondc, bpp, bpm, tpp), analyzing their water sorption behavior and the water interactions
    in the confined pore space. For this purpose, we apply water vapor sorption analysis
    and Fourier transform infrared spectroscopy. In addition, defect degrees of all
    compounds are determined by thermogravimetric analysis and solution 1H nuclear
    magnetic resonance spectroscopy. We find that larger defect degrees affect the
    preferential sorption sites in Ni2dhtp, while no such indication is found for
    the other materials in our study. Instead, strong evidence is found for the formation
    of water bridges/chains between coordinating water molecules, as previously observed
    for hydrophobic porous carbons and mesoporous silica. This suggests similar sorption
    energies for additional water molecules in materials with larger pore sizes after
    saturation of the primary binding sites, resulting in more bulk-like water arrangements.
    Consequently, the sorption mechanism is driven by classical pore condensation
    through H-bonding anchor sites instead of sorption at discrete sites.</jats:p>

  text: CPO‐27 is a metal‐organic framework (MOF) with coordinatively unsaturated
    metal centers (open metal sites). It is therefore an ideal host material for small
    guest molecules, including water. This opens up numerous possible applications,
    such as proton conduction, humidity sensing, water harvesting, or adsorption‐driven
    heat pumps. For all of these applications, profound knowledge of the adsorption
    and desorption of water in the micropores is mandatory. The hydration and water
    structure in CPO‐27‐M (M = Zn or Cu) is investigated using water vapor sorption,
    Fourier transform infrared (FTIR) spectroscopy, density functional theory (DFT)
    calculations, and molecular dynamics simulation. In the pores of CPO‐27‐Zn, water
    binds as a ligand to the Zn center. Additional water molecules are stepwise incorporated
    at defined positions, forming a network of H‐bonds with the framework and with
    each other. In CPO‐27‐Cu, hydration proceeds by an entirely different mechanism.
    Here, water does not coordinate to the metal center, but only forms H‐bonds with
    the framework; pore filling occurs mostly in a single step, with the open metal
    site remaining unoccupied. Water in the pores forms clusters with extensive intra‐cluster
    H‐bonding.

  text: Clean hydrogen is a key aspect of carbon neutrality, necessitating robust
    methods for monitoring hydrogen concentration in critical infrastructures like
    pipelines or power plants. While semiconducting metal oxides such as In2O3 can
    monitor gas concentrations down to the ppm range, they often exhibit cross-sensitivity
    to other gases like H2O. In this study, we investigated whether cyclic optical
    illumination of a gas-sensitive In2O3 layer creates identifiable changes in a
    gas sensor´s electronic resistance that can be linked to H2 and H2O concentrations
    via machine learning. We exposed nanostructured In2O3 with a large surface area
    of 95 m2 g-1 to H2 concentrations (0-800 ppm) and relative humidity (0-70%) under
    cyclic activation utilizing blue light. The sensors were tested for 20 classes
    of gas combinations. A support vector machine achieved classification rates up
    to 92.0%, with reliable reproducibility (88.2 ± 2.7%) across five individual sensors
    using 10-fold cross-validation. Our findings suggest that cyclic optical activation
    can be used as a tool to classify H2 and H2O concentrations.

  text: Self-templating is a facile strategy for synthesizing porous carbons by direct
    pyrolysis of organic metal salts. However, the method typically suffers from low
    yields (<4%) and limited specific surface areas (SSA<2000 m2 g−1) originating
    from low activity of metal cations (e.g., K+ or Na+) in promoting construction
    and activation of carbon frameworks. Here we use cesium acetate as the only precursor
    of oxo-carbons with large SSA of the order of 3000 m2 g−1, pore volume approaching
    2 cm3 g−1, tunable oxygen contents, and yields of up to 15 %. We unravel the role
    of Cs+ as an efficient promoter of framework formation, templating and etching
    agent, while acetates act as carbon/oxygen sources of carbonaceous frameworks.
    The oxo-carbons show record-high CO2 uptake of 8.71 mmol g−1 and an ultimate specific
    capacitance of 313 F g−1 in the supercapacitor. This study helps to understand
    and rationally tailor the materials design by a still rare organic solid-state
    chemistry.

  text: The Saharan desert ant Cataglyphis bombycina is densely covered with shiny
    silver setae (hair-like structures). Their appearance was explained by geometric
    optics and total internal reflection. The setae also increase the emissivity of
    the ant, as they form an effective medium. This work provides additional data
    on microstructural details of the setae that are used to simulate the scattering
    of an individual seta to explain their influence on the optical properties. This
    is achieved by characterization of their structure using light microscopy and
    scanning/transmission electron microscopy. How the microstructural features influence
    scattering is investigated wave-optically within the limits of finite-difference
    time-domain simulations from the ultraviolet to the mid-infrared spectral range
    to elucidate the optical effects beyond ray optics and effective medium theory.
    The results show that Mie scattering plays an important role in protecting the
    ant from solar radiation and could be relevant for its thermal tolerance.

  text: The production of hydrogen and the utilization of biomass for sustainable
    concepts of energy conversion and storage require gas sensors that discriminate
    between hydrogen (H2) and carbon monoxide (CO). Mesoporous copper–ceria (Cu–CeO2)
    materials with large specific surface areas and uniform porosity are prepared
    by nanocasting, and their textural properties are characterized by N2 physisorption,
    powder XRD, scanning electron microscopy, transmission electron microscopy, and
    energy-dispersive X-ray spectroscopy. The oxidation states of copper (Cu+, Cu2+)
    and cerium (Ce3+, Ce4+) are investigated by XPS. The materials are used as resistive
    gas sensors for H2 and CO. The sensors show a stronger response to CO than to
    H2 and low cross-sensitivity to humidity. Copper turns out to be a necessary component;
    copper-free ceria materials prepared by the same method show only poor sensing
    performance. By measuring both gases (CO and H2) simultaneously, it is shown that
    this behavior can be utilized for selective sensing of CO in the presence of H2.

  text: Hydrothermal carbonization (HTC) is an efficient thermochemical method for
    the conversion of organic feedstock to carbonaceous solids. HTC of different saccharides
    is known to produce microspheres (MS) with mostly Gaussian size distribution,
    which are utilized as functional materials in various applications, both as pristine
    MS and as a precursor for hard carbon MS. Although the average size of the MS
    can be influenced by adjusting the process parameters, there is no reliable mechanism
    to affect their size distribution. Our results demonstrate that HTC of trehalose,
    in contrast to other saccharides, results in a distinctly bimodal sphere diameter
    distribution consisting of small spheres with diameters of (2.1 ± 0.2) μm and
    of large spheres with diameters of (10.4 ± 2.6) μm. Remarkably, after pyrolytic
    post-carbonization at 1000 °C the MS develop a multimodal pore size distribution
    with abundant macropores > 100 nm, mesopores > 10 nm and micropores < 2 nm, which
    were examined by small-angle X-ray scattering and visualized by charge-compensated
    helium ion microscopy. The bimodal size distribution and hierarchical porosity
    provide an extraordinary set of properties and potential variables for the tailored
    synthesis of hierarchical porous carbons, making trehalose-derived hard carbon
    MS a highly promising material for applications in catalysis, filtration, and
    energy storage devices.

  text: Faradaic reactions including charge transfer are often accompanied with diffusion
    limitation inside the bulk. Conductive two-dimensional frameworks (2D MOFs) with
    a fast ion transport can combine both - charge transfer and fast diffusion inside
    their porous structure. To study remaining diffusion limitations caused by particle
    morphology, different synthesis routes of Cu-2,3,6,7,10,11-hexahydroxytriphenylene
    (Cu3(HHTP)2), a copper-based 2D MOF, are used to obtain flake- and rod-like MOF
    particles. Both morphologies are systematically characterized and evaluated for
    redox-active Li+ ion storage. The redox mechanism is investigated by means of
    X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are
    compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry
    and impedance spectroscopy. A significant influence of particle morphology for
    2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed.
    This study opens the path for optimization of redox active porous structures to
    overcome diffusion limitations of Faradaic processes.

    which has a strong effect on proton conductivity. In the Mg-based coordination
    network, dangling sulfonate groups are part of an extended hydrogen bonding network,
    facilitating a “proton hopping” with low activation energy; the material shows
    a moderate proton conductivity. In the Pb-based metal-organic framework, in contrast,
    no extended hydrogen bonding occurs, as the sulfonate groups coordinate to Pb<jats:sup>2+</jats:sup>,
    without forming hydrogen bonds; the proton conductivity is much lower in this

  text: Near ambient pressure XPS in nitrogen atmosphere was utilized to investigate
    gas-solid interactions within porous SiO2 films ranging from 30 to 75 nm thickness.
    The films were differentiated in terms of porosity and roughness. The XPS N1s
    core levels of the N2 gas in presence of the SiO2 samples showed variations in
    width, binding energy and line shape. The width correlated with the surface charge
    induced in the dielectric films upon X-ray irradiation. The observed different
    binding energies observed for the N1s peak can only partly be associated with
    intrinsic work function differences between the samples, opening the possibility
    that the effect of physisorption at room temperature could be detected by a shift
    in the measured binding energy. However, the signals also show an increasing asymmetry
    with rising surface charge. This might be associated with the formation of vertical
    electrical gradients within the dielectric porous thin films, which complicates
    the assignment of binding energy positions to specific surface-related effects.
    With the support of Monte Carlo and first principles density functional theory
    calculations, the observed shifts were discussed in terms of the possible formation
    of transitory dipoles upon N2 physisorption within the porous SiO2 films.

  text: In the spatial confinement of cylindrical mesopores with diameters of a few
    nanometers, water molecules experience restrictions in hydrogen bonding. This
    leads to a different behavior regarding the molecular orientational freedom (‘structure
    of water') compared to the bulk liquid state. In addition to the pore size, the
    behavior is also strongly affected by the strength of the pore wall-to-water interactions,
    that is, the pore wall polarity. In this work, this is studied both experimentally
    and theoretically. The surface polarity of mesoporous silica (SiO2) is modified
    by functionalization with trimethylsilyl moieties, resulting in a change from
    a hydrophilic (pristine) to a hydrophobic pore wall. The mesopore surface is characterized
    by N2 and H2O sorption experiments. Those results are combined with IR spectroscopy
    to investigate pore wall-to-water interactions leading to different structures
    of water in the mesopore. Furthermore, the water's structure is studied theoretically
    to gain deeper insight into the interfacial interactions. For this purpose, the
    structure of water is analyzed by pairing densities, coordination, and angular
    distributions with a novel adaptation of surface-specific sum-frequency generation
    calculation for pore environments.

  text: The electrochemical properties of carbonaceous materials produced by hydrothermal
    carbonization, referred to as hydrochar, can be substantially improved by post-carbonization
    via pyrolysis. Although these materials have been widely studied for a variety
    of applications, the mechanisms underlying the pyrolysis are yet poorly understood.
    This study provides a comprehensive temperature-resolved characterization of the
    chemical composition, morphology and crystallinity of sucrose-derived hydrochar
    during pyrolysis. Thermogravimetric analysis, differential scanning calorimetry,
    and elemental analysis have shown that the dry hydrochar loses about 41% of its
    dry mass due to the exothermic disintegration of oxygen-containing groups until
    the carbonization is completed at about 850 °C with a total carbon yield of 93%.
    The carbonization and aromatization of the initially furanic and keto-aliphatic
    structure were analyzed by 13C solid-state nuclear magnetic resonance spectroscopy,
    X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy.
    The transition from an amorphous to a nanocrystalline graphitic structure was
    analyzed using X-ray diffraction and Raman spectroscopy. The pore formation mechanism
    was examined by helium ion microscopy, transmission electron microscopy, and nitrogen
    adsorption measurements. The results indicate the formation of oxygen-rich nanoclusters
    up to 700 °C, which decompose up to 750 °C leaving behind equally sized pores,
    resulting in a surface area of up to 480 m2/g.
