Inspired by the high osmotic dehydration effect in medicine, this study introduces an equimolar ZnSO<small>₄</small>/<small>D</small>-mannitol (MNT) electrolyte to stabilize the Zn anodes. Comprehensive spectrochemical characterization and theoretical calculations, coupled with rigorous electrochemical and electroanalytical tests, show that the hydroxyl-rich MNT strongly interacts with water, reducing hydrogen bonds and reshaping solvation structures of hydrated Zn<small>²⁺</small>, thereby effectively suppressing corrosion and side reactions. Furthermore, the preferential adsorption of MNT at the Zn anode surface regulates the interfacial reaction environment, enabling dendrite-free, orderly-stacked and corrosion-less Zn deposition. This is confirmed by backscattered-electron scanning electron microscopy observations on cycled electrodes prepared using a cross-section polisher. As a result, the use of a <small>D</small>-mannitol-enriched ZnSO<small>₄</small> electrolyte extends the cycle life of Zn||Zn symmetric cells to over 2980 hours and significantly enhances the long-term cycling performance of Zn||PANI (polypyrrole–polyaniline) full cells at a low N/P ratio of 22.48.</p>","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 1","pages":" 61-68"},"PeriodicalIF":0.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d4lf00328d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intricate structures of mycelial hyphae fibrils were replicated with high precision using an inexpensive commercial silane (3-aminopropyl)-triethoxysilane (APTES). Following the removal of the organic mycelium template phase at 600 °C, APTES was successfully converted to SiO<small>_<em>x</em></small>. The resulting SiO<small>_<em>x</em></small> fibres retained the morphology of the mycelium template, with a nearly identical fibre density to the original fibrous network. A fibril diameter reduction of approximately 43% was observed from 603 to 344 nm. All synthesised materials exhibited coherent structural integrity, sufficient for handling without breakage, although they were notably less mechanically flexible than the original mycelium template. The novel hybrid mycelium-3-aminopropyl-silsesquioxane fibre network and the thermally converted SiO<small>_<em>x</em></small> network displayed notable liquid absorption properties. These materials allowed for the preferential absorption of oil or water, depending on the presence of the amino group functionality. Remarkably, the SiO<small>_<em>x</em></small> network rapidly absorbed methylene blue-dyed water within 400 ms, demonstrating behaviour opposite to the virgin mycelium network. Additionally, the materials exhibited high thermal stability, withstanding flame exposure at approximately 1400 °C while maintaining their nano/micromorphology. This innovative approach of using “living” templates expands the range of morphologies that can be replicated in inorganic materials, enabling the creation of genetically and environmentally tuneable structures.

MOFs can achieve improved flame retardant qualities by modifying metal ions or adding flame retardant components to their ligands. Although MOFs' organic ligands can somewhat enhance their compatibility with the polymer matrix, their agglomeration in the matrix remains unavoidable which diminishes their effectiveness. Research indicates that surface modification of MOFs can enhance interface interactions with the polymer matrix. Consequently, modifying the surface of MOFs is crucial. Here, we categorize methods for modifying the surface structure of MOFs and examine the flame-retardant effects of various modification techniques, emphasizing the development of MOFs' surface morphology and its compatibility with the polymer matrix. In addition, we discuss the economic significance and sustainability of surface-modified MOFs compared to conventional flame retardants.

In this work, we report on the chemical synthesis, barium capture ability and photophysical properties of two families of monocolor and bicolor fluorescent sensors. These sensors were prepared to capture barium cations that can be produced in neutrinoless double beta decay of Xe-136. These sensors incorporate crown ether units, two different fluorophores, aliphatic spacers of different lengths, and a silatrane linker that forms covalent bonds with indium tin oxide (ITO) surfaces. Both species shared excellent Ba<small>²⁺</small> binding abilities. Fluorescent monocolor indicators (FMIs), based on naphthyl fluorophores, showed an off–on character in solution controlled by photoinduced electron transfer. Fluorescent bicolor indicators (FBIs), based on benzo[<em>a</em>]imidazo[5,1,2-<em>cd</em>] fluorophores, exhibited a significant change in their emission spectra on going from the free to the barium-bound state. Both FMIs and FBIs showed similar photophysics in solution and on ITO. However, their performance on ITO was found to be attenuated, but not fully extinguished, with respect to the values obtained in solution, both in terms of intensity and selectivity between the free and Ba<small>²⁺</small>-bound states. Despite this issue, improved performance of the FBIs based on confocal microscopy of the directly attached molecules was observed. These selective FMI and FBI chemosensors installed on tailor-made functionalized surfaces are promising tools to capture the barium cations produced in the double beta decay of Xe-136.

However, a major barrier for hydrogen economy is the challenges associated with the efficient storage of hydrogen, due to its low density, ultra-low boiling point, and extreme volatility. Current practice of using high-pressure tanks has safety concerns and is costly. As a potential solution, adsorption-based hydrogen storage using porous materials has shown great promise due to fast kinetics and their ability to store a comparable amount of hydrogen at much lower pressure. This approach takes advantage of physisorption of hydrogen in porous materials with high surface areas. A number of different classes of materials have been studied for adsorption-based hydrogen storage. Among these materials, porous carbon has shown great promise due to its high surface area, tunable pore size, versatile surface chemistry, scalability, and high chemical and thermal stability. This review provides a comprehensive overview of porous carbon materials, such as graphene, carbon nanotubes, and activated carbons, for hydrogen storage. We delve into the fundamental principles and mechanisms behind adsorptive hydrogen storage, focusing on the critical roles of surface area, pore size, and surface chemistry in determining hydrogen uptake. Strategies to enhance hydrogen storage capacity through structural and chemical modifications are discussed. Additionally, we examine the life cycle assessment of porous carbons and explore recent advancements in machine learning applications to optimize their performance.

We studied the lipid hydrolysis kinetics of OmpLA in charge-neutral and charged membranes with symmetric or asymmetric transbilayer lipid distributions. In charge-neutral membranes, OmpLA was more active in symmetric bilayers due to the lower differential curvature stress between membrane leaflets. Strikingly, this behavior was completely reversed in charged bilayers. Measurements revealed intrinsic molecular shape changes in the charged lipids upon addition of calcium. This effectively reduces the differential curvature stress in charged asymmetric membranes leading to increased protein activity. This conclusion is further supported by similar effects observed upon the addition of sodium ions, which also alter the shape of the lipids, but do not specifically interact with the protein. Additional lipid–protein interactions likely contribute to this phenomenon.
