Summary: This study presents a novel hybrid inorganic-organic architecture called polyionic nanoclays (PINCs), which are composed of two-dimensional, few nanometer-thick magnesium phyllo(organo)silicate nanosheets with ordered imidazolium functionalities. The PINCs demonstrate high ionic density, exchangeability of counteranions, and the ability to tailor the organic component, showing promising potential in catalysis, ion exchange, energy storage, and other applications. Additionally, the study also reveals the remarkable catalytic activity of gold nanoparticles supported on PINCs, suggesting a major synergistic effect compared to similar nanoparticles suspended in water.

Summary: An ultrafast and cost-effective hot-pressing method was developed to fabricate a novel carbon-based hybrid film consisting of ionic liquid/phenolic resin/carbon fiber/expanded graphite, taking no more than 15 minutes. The hybrid film showed high flexibility due to the presence of expanded graphite, and the introduction of phenolic resin and carbon fiber improved its shear resistance and toughness. The ion-induced carrier migration contributed to a high power factor of 38.7 μWm(-1) K-2 at 500 K. Comparing with current conventional carbon-based thermoelectric composites, the hybrid film exhibited the best cost-effective property based on the power factor, fabrication time, and cost ratios. Additionally, a flexible thermoelectric device assembled with the hybrid films achieved a maximum output power density of 79.3 nW cm(-2) at a temperature difference of 20 K. This work provides a new approach for fabricating cost-effective and high-performance carbon-based thermoelectric hybrids with promising application potential.

Summary: The dispersion of nanoparticles allows the tuning of optical parameters in liquid crystalline materials. This study investigates the effect of different concentrations of porous carbon nanoparticles (PCNPs) on the optical properties of a nematic liquid crystal (NLC) as a guest-host system. The presence of PCNPs leads to increased photoluminescence intensity and reduced optical bandgap in the NLC. This work is significant for applications in liquid crystal displays and the development of low bandgap materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
