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.","lang":"eng"}],"publication":"International Journal of Biological Macromolecules","language":[{"iso":"eng"}]},{"type":"journal_article","publication":"Microporous and Mesoporous Materials","abstract":[{"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.","lang":"eng"}],"status":"public","_id":"56265","user_id":"23547","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["1387-1811"]},"year":"2025","citation":{"apa":"Kloß, M., Weinberger, C., &#38; Tiemann, M.

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.","lang":"eng"}],"date_created":"2024-03-08T06:27:10Z","publisher":"The Electrochemical Society","title":"Electrochemical Removal of HF from Carbonate-based LiPF6-containing Li-ion Battery Electrolytes","quality_controlled":"1","year":"2024"},{"publication":"Nanomaterials","abstract":[{"lang":"eng","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>"}],"language":[{"iso":"eng"}],"issue":"22","quality_controlled":"1","year":"2024","date_created":"2024-11-08T06:18:11Z","publisher":"MDPI AG","title":"Water Sorption on Isoreticular CPO-27-Type MOFs: From Discrete Sorption Sites to Water-Bridge-Mediated Pore Condensation","type":"journal_article","status":"public","user_id":"23547","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"_id":"56947","article_type":"original","publication_status":"published","publication_identifier":{"issn":["2079-4991"]},"citation":{"ama":"Kloß M, Schäfers L, Zhao Z, Weinberger C, Egold H, Tiemann M.

Additional water molecules are stepwise incorporated at defined positions, forming a network of H‐bonds with the framework and with each other.

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.

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."}],"language":[{"iso":"eng"}],"keyword":["General Chemical Engineering","General Chemistry"],"issue":"21","quality_controlled":"1","year":"2023","date_created":"2023-05-12T07:16:15Z","publisher":"Royal Society of Chemistry (RSC)","title":"Hard carbon microspheres with bimodal size distribution and hierarchical porosity <i>via</i> hydrothermal carbonization of trehalose"},{"intvolume":"       264","citation":{"ieee":"H.

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.","lang":"eng"}],"status":"public","publication":"Applied Surface Science","type":"journal_article","keyword":["Surfaces","Coatings and Films","Condensed Matter Physics","Surfaces and Interfaces","General Physics and Astronomy","General Chemistry"],"article_type":"original","article_number":"154525","language":[{"iso":"eng"}],"_id":"33691","department":[{"_id":"613"},{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"302"},{"_id":"304"}],"user_id":"23547","year":"2022","intvolume":"       604","citation":{"chicago":"Arcos, Teresa de los, Christian Weinberger, Frederik Zysk, Varun Raj Damerla, Sabrina Kollmann, Pascal Vieth, Michael Tiemann, Thomas Kühne, and Guido Grundmeier. “Challenges in the Interpretation of Gas Core Levels for the Determination of Gas-Solid Interactions within Dielectric Porous Films by Ambient Pressure XPS.” <i>Applied Surface Science</i> 604 (2022). <a href=\"https://doi.org/10.1016/j.apsusc.2022.154525\">https://doi.org/10.1016/j.apsusc.2022.154525</a>.","ieee":"T. de los Arcos <i>et al.</i>, “Challenges in the interpretation of gas core levels for the determination of gas-solid interactions within dielectric porous films by ambient pressure XPS,” <i>Applied Surface Science</i>, vol. 604, Art. no. 154525, 2022, doi: <a href=\"https://doi.org/10.1016/j.apsusc.2022.154525\">10.1016/j.apsusc.2022.154525</a>.","ama":"de los Arcos T, Weinberger C, Zysk F, et al.

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."}],"publication":"Advanced Materials Interfaces"},{"language":[{"iso":"eng"}],"keyword":["Analytical Chemistry","Fuel Technology"],"abstract":[{"lang":"eng","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."}],"publication":"Journal of Analytical and Applied Pyrolysis","title":"Pyrolysis of sucrose-derived hydrochar","date_created":"2022-01-18T06:25:06Z","publisher":"Elsevier BV","year":"2022","quality_controlled":"1","article_number":"105404","article_type":"original","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"315"}],"user_id":"23547","_id":"29376","status":"public","type":"journal_article","doi":"10.1016/j.jaap.2021.105404","volume":161,"author":[{"first_name":"Martin","full_name":"Wortmann, Martin","last_name":"Wortmann"},{"full_name":"Keil, Waldemar","last_name":"Keil","first_name":"Waldemar"},{"full_name":"Brockhagen, Bennet","last_name":"Brockhagen","first_name":"Bennet"},{"full_name":"Biedinger, Jan","last_name":"Biedinger","first_name":"Jan"},{"first_name":"Michael","full_name":"Westphal, Michael","last_name":"Westphal"},{"first_name":"Christian","full_name":"Weinberger, Christian","id":"11848","last_name":"Weinberger"},{"last_name":"Diestelhorst","full_name":"Diestelhorst, Elise","first_name":"Elise"},{"full_name":"Hachmann, Wiebke","last_name":"Hachmann","first_name":"Wiebke"},{"full_name":"Zhao, Yanjing","last_name":"Zhao","first_name":"Yanjing"},{"first_name":"Michael","last_name":"Tiemann","orcid":"0000-0003-1711-2722","id":"23547","full_name":"Tiemann, Michael"},{"last_name":"Reiss","full_name":"Reiss, Günter","first_name":"Günter"},{"full_name":"Hüsgen, Bruno","last_name":"Hüsgen","first_name":"Bruno"},{"orcid":"0000-0003-3179-9997","last_name":"Schmidt","full_name":"Schmidt, Claudia","id":"466","first_name":"Claudia"},{"last_name":"Sattler","full_name":"Sattler, Klaus","first_name":"Klaus"},{"last_name":"Frese","full_name":"Frese, Natalie","first_name":"Natalie"}],"date_updated":"2023-03-08T08:15:24Z","intvolume":"       161","citation":{"ieee":"M.

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.","lang":"eng"}],"status":"public","publication":"Microporous and Mesoporous Materials","type":"journal_article","title":"Modeling of gyroidal mesoporous CMK-8 and CMK-9 carbon nanostructures and their X-Ray diffraction patterns","doi":"10.1016/j.micromeso.2020.110330","date_updated":"2023-03-07T10:44:44Z","author":[{"first_name":"Bertram","last_name":"Schwind","full_name":"Schwind, Bertram"},{"full_name":"Smått, Jan-Henrik","last_name":"Smått","first_name":"Jan-Henrik"},{"first_name":"Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann","id":"23547","full_name":"Tiemann, Michael"},{"last_name":"Weinberger","id":"11848","full_name":"Weinberger, Christian","first_name":"Christian"}],"date_created":"2021-10-08T10:02:31Z","year":"2021","citation":{"apa":"Schwind, B., Smått, J.-H., Tiemann, M., &#38; Weinberger, C.

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."}],"type":"journal_article","publication":"Vibrational Spectroscopy"},{"publication_identifier":{"issn":["2196-7350","2196-7350"]},"quality_controlled":"1","publication_status":"published","citation":{"apa":"Tiemann, M., &#38; Weinberger, C.

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."}],"department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547","_id":"25893","language":[{"iso":"eng"}],"article_number":"2001153","article_type":"review"}]
