  text: Proton exchange membranes (PEMs) are essential for fuel cells, yet conventional
    materials like Nafion suffer from humidity dependence and limited thermal stability.
    This study introduces sulfonated phenylene-bridged periodic mesoporous organosilicas
    (PMOs) as promising inorganic–organic hybrid PEMs, synthesized via surfactant-templating
    with varying alkyl chain lengths for different mesopore sizes. Post-synthetic
    functionalization involves nitration of phenylene moieties, reduction to amines,
    and ring-opening of propane or butane sultones to graft sulfonic acid groups via
    flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization
    is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal
    p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms
    with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization
    degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities
    up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization
    degree, confirming sulfonic acid-mediated conduction.

  text: 'Spray-induced gene silencing (SIGS) employing double-stranded RNA (dsRNA)
    offers a promising, species-specific approach for protecting crops from insect
    pests such as the cabbage stem flea beetle (Psylliodes chrysocephala). However,
    the environmental instability of dsRNA presents a major limitation to its field
    application. In this study, we evaluate two distinct dsRNA formulation strategies
    for improved stability and delivery: a bottom-up approach using chitosan-based
    interpolyelectrolyte complexes (IPEC) and a top-down approach employing functionalized
    mesoporous silica carriers (SBA-15). Both systems were comprehensively characterized
    in terms of size, surface potential, porosity, and release behavior. The results
    revealed that IPECs exhibited release kinetics that were approximately one order
    of magnitude faster than those of SBA-15 across all tested conditions. The two
    formulations significantly improved dsRNA stability against UV and heat exposure
    compared to free dsRNA. In feeding assays with P. chrysocephala, both carriers
    achieved comparable gene silencing efficacy, though dsRNA@IPEC induced more immediate
    effects, while dsRNA@SBA-15 displayed delayed but ultimately stronger reduction
    in consumed leaf area, consistent with its slower release kinetics. We demonstrate
    that despite structural and mechanistic differences, both delivery platforms effectively
    stabilized and delivered dsRNA, and offered distinct advantages depending on application
    needs. This work highlights how formulation strategies are key to successful SIGS
    and supports the development of robust, field-adaptable formulation technologies
    for sustainable pest management.'

  text: The metal-organic framework CPO-27 exhibits free coordination sites (open
    metal sites) and can be prepared with a wide range of metals that influence its
    properties. It is therefore an intriguing structure to study sorption phenomena.
    We analyze the water resistance and sorption behavior of these frameworks, with
    particular attention to the sorption mechanism in detail and the structure of
    the confined water molecules. For this purpose, we use manometric water vapor
    sorption analysis and FTIR spectroscopy. The respective metal center orchestrates
    both the adsorption behavior and the arrangement of the water molecules in the
    micropores of the framework. The extent to which water molecules form hydrogen
    bonds (with each other and with framework oxygen atoms) plays a crucial role in
    the stability of the framework towards water. Water adsorption is governed by
    the coordination of water molecules to the open metal sites (except for CPO-27-Cu)
    and subsequent H-bonding. A stepwise adsorption of water is observed, with significant
    differences depending on the choice of metal.

  text: Zinc tin oxide (ZTO) is investigated as a photoluminescent sensor for oxygen
    (O2); chemisorbed oxygen quenches the luminescence intensity. At the same time,
    ZTO is also studied as a resistive sensor; being an n‐type semiconductor, its
    electrical conductance decreases by adsorption of oxygen. Both phenomena can be
    exploited for quantitative O2 sensing. The respective sensor responses can be
    described by the same modified Stern‐Volmer model that distinguishes between accessible
    and non‐accessible luminescence centers or charge carriers, respectively. The
    impact of the temperature is studied in the range from room temperature up to
    150 °C.

  text: <jats:title>Abstract</jats:title><jats:p>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, NO<jats:italic><jats:sub>x</jats:sub></jats:italic>, and O<jats:sub>2</jats:sub>.
    Oxygen sensors typically incorporate dyes into oxygen‐permeable matrices like
    polymers, silica, or zeolites. Alternatively, semiconductor surface chemistry
    can enable O<jats:sub>2</jats:sub> 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 O<jats:sub>2</jats:sub> concentrations. Time‐resolved emission
    measurements are performed over short (seconds) and long (hours) timescales using
    N<jats:sub>2</jats:sub> 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 O<jats:sub>2</jats:sub>. These results highlight the potential
    of MOF‐76‐based materials for high‐performance O<jats:sub>2</jats:sub> sensing.</jats:p>

    (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: 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.
