  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.

    Oxygen sensors typically incorporate dyes into oxygen‐permeable matrices like

    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),

    Unlike MOF‐76(Eu), MIL‐78(Eu) exhibits distinct optical properties but lacks a

  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: <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 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: 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.

  text: With the rapid advances of functional dielectric metasurfaces and their integration
    on on-chip nanophotonic devices, the necessity of metasurfaces working in different
    environments, especially in biological applications, arose. However, the metasurfaces’
    performance is tied to the unit cell’s efficiency and ultimately the surrounding
    environment it was designed for, thus reducing its applicability if exposed to
    altering refractive index media. Here, we report a method to increase a metasurface’s
    versatility by covering the high-index metasurface with a low index porous SiO2
    film, protecting the metasurface from environmental changes while keeping the
    working efficiency unchanged. We show, that a covered metasurface retains its
    functionality even when exposed to fluidic environments.

  text: Powder X-ray diffraction (XRD) patterns of ordered mesoporous CMK-8 and CMK-9
    carbon materials are simulated by geometric modeling. The materials are amorphous
    at the atomic length scale but exhibit highly symmetric gyroidal structures at
    the nanometer scale, corresponding to regular, continuous nanopore systems with
    cubic symmetry. 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.

  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.

  text: Tailor-made ordered mesoporous materials bear great potential in numerous
    fields of application where large interfaces are required. 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.
