Summary: A novel SPEEK-based blend proton exchange membrane containing liquid crystal polymer intercalated montmorillonite (LCT) was prepared by solution casting technology. The composite membrane showed higher swelling rate and proton conductivity with 1.0 wt% LCT content. The proton conductivity of the composite membrane decreased, but reached 0.137 S/cm when the LCT content was 1.0 wt%, and the swelling rate of the SPEEK membrane significantly decreased from 6.19% to 3.38%. The layer silicate structure in LCT promoted its dimensional stability, and the sulfonic group formed a hydrogen bond network in the SPEEK matrix to enhance proton transfer. These findings suggest that the composite membrane has potential as a candidate for PEMFC at 25 degrees C.

Summary: The preparation of composite proton exchange membranes (PEMs) by incorporating metal-organic frameworks (MOFs) into polymeric substrates has been a popular research topic in the field of fuel cells. In this study, a composite membrane SPEEK/ZSCx was fabricated by introducing ZSC into sulfonated poly(ether ether ketone) (SPEEK). The coating treatment of carbon nanotubes (CNTs) with silica improved the dispersion in SPEEK matrix and regulated the nucleation and crystallization process of ZIF-8 particles. The resulting SPEEK/ZSC composite membranes showed improved performance, with higher proton conductivity and power density compared to the pure SPEEK membrane. The stability tests also confirmed the excellent voltage stability of the composite film even after continuous operation for 100 hours at 80 degrees C.

Summary: Poly(fluorenyl terphenyl piperidinium) (PFTP) with an aromatic backbone was synthesized to produce proton exchange membranes (PEMs) with robust mechanical properties. The introduction of propanesulfonic acid side chains enhanced the phosphoric acid (PA) adsorption capacity and proton conductivity of the resulting sulfonated PFTP (SPFTP-x) membranes. These membranes exhibited good thermal, oxidization, and dimensional stabilities, and the SPFTP-x membranes showed higher PA adsorption capacity and higher proton conductivity than the PFTP membrane. A single cell assembled with SPFTP-50 exhibited a maximum power density of 280 mW cm-2 at 100 degrees C, indicating the promising application of SPFTP-x as a membrane material for high-temperature proton membrane fuel cells.

Summary: By changing the preparation and pretreatment conditions, the properties of Nafion membranes can be optimized. In this study, a Nafion-NMP membrane with higher conductivity and comparable hydrogen permeability was obtained by casting from a Nafion dispersion in N-methyl-2-pyrrolidone. The increase in conductivity is attributed to the optimization of the Nafion-NMP microstructure, which improves the connectivity of the pores and channels system. This leads to an increased capacity of the membrane electrode assembly compared to a commercial Nafion (R) 212 membrane.

Summary: In this study, a nanoarchitectonics approach was used to fabricate biohybrid materials for trapping living cells. Cyanobacteria and yeast cells were immobilized in silica and silicate-based substrates organized as nanostructured materials. The use of bionanocomposites of chitosan and alginate incorporating sepiolite clay mineral in films, beads, or foams showed initial problems with the long-term survival of the encapsulated microorganisms. However, alternative procedures using low sodium content silica-based matrices and pre-synthesized yolk-shell bionanohybrids improved the encapsulation efficiency and cell survival.

Summary: This study develops various nanostructured materials by assembling SiO2, TiO2, and ZnO nanoparticles to sepiolite fibers (Sep) and incorporating them as fillers of Nafion to enhance proton exchange membrane performance in fuel cell applications. Different nanoarchitectures, SiO2-Sep, TiO2-SiO2-Sep, and ZnO@SiO2-Sep, are synthesized through a colloidal route utilizing controlled hydrolysis of alkoxide precursors (tetramethoxysilane and titanium tetraisopropoxide) with hexadecyltrimethylammonium-sepiolite. The resulting nanoarchitectures show successful nanoparticle formation and assembly onto the clay surface, confirmed by XRD, FTIR, SEM, TEM, and N2 adsorption-desorption isotherms. Nafion-based composite membranes containing these nanoarchitectures exhibit improved thermal properties, water uptake, and proton conductivity compared to neat Nafion membranes, demonstrating their potential for proton exchange membrane fuel cell applications.

Summary: This paper presents the synthesis and characterization of a novel polyketimine (PKI) membrane and the introduction of laser-induced graphene electrodes (LIGEs) for efficient electrochemical sensing of paracetamol (PCM). The LIGEs showed excellent performance in PCM sensing, with a linear detection range of 50-600 μM and a low detection limit of 14.3 μM. Functionalization of the electrode surface with AuNPs further improved the electrode properties and lowered the detection limit to 1.1 μM. These affordable electrodes hold great potential for analyzing other drugs and detecting heavy metal cations in various applications.

Summary: Rutile nano-TiO2 was loaded onto the surface of sericite to prepare sericite-rutile composite particles, which were then modified with HDTMS and sprayed onto the substrates to form sericite-rutile/HDTMS composite coatings with UV shielding and superhydrophobic self-cleaning properties. The coating exhibited good UV shielding rate and remained superhydrophobic after UV irradiation. The hierarchical structure of the sericite-rutile composite and the low surface energy of HDTMS contributed to the superhydrophobicity and UV shielding effect of the coating.

Summary: Environmental conditions significantly influence clay minerals, and studying clay sediments in tropical lakes can provide valuable insights into past environmental conditions. In this study, multiproxy records from sediment cores of three crater lakes in central Mexico were analyzed. The results showed that disordered kaolinite, formed through hydrolysis and hydrothermal alteration, was the predominant mineral in the sediments. The abundance of kaolinite varied in relation to organic carbon and organic matter-related elements, and showed opposite trends with lithogenic elements. Geochemical data suggested that the increase in kaolinite abundance is linked to the formation of organo-mineral aggregates and lake level changes in closed basins.

It was found that CMC showed stronger adsorption on the edge plane of talc due to enhanced interactions with polar groups and water molecules. The study also revealed specific interactions between H atoms in CMC and O atoms in the edge plane, as well as between O atoms in CMC and Si, Mg atoms in the edge plane. Hydration shells on the basal and edge planes of talc were examined to explain the phenomenon.
