Summary: This study investigates the hybrid CTAB and GO LLC system, finding that GO can either promote or suppress the formation of different LLC phases of CTAB, resulting in a complex hybrid system. Furthermore, GO significantly depresses the melting point of CTAB at moderate loadings, but the melting point recovers for higher GO loading.

Summary: Iron-driven secondary brown carbon formation reactions from water-soluble organics in cloud droplets and aerosols create insoluble and soluble products of emerging atmospheric importance. This study demonstrates that under conditions of high ionic strength and acidic pH, insoluble black polycatechol particles and colored water-soluble oligomers can be formed. By controlling reaction conditions and adding specific components, the rate of brown carbon formation and product formation can be modulated.

Summary: The study investigates the adsorption behavior of cetyltrimethylammonium bromide (CTAB) on synthesized alpha aluminum hydroxide nanomaterials and its application in removing the pesticide lindane. The high-purity alpha-Al(OH)3 was confirmed through various methods. Electrostatic attraction between CTAB ions and the negatively charged alpha-Al(OH)3 surface increased the adsorption of CTAB with increasing pH. CTAB modified aluminum hydroxide nanoparticles (CMAH) achieved a 95% removal of lindane under optimum conditions. The study demonstrates that CMAH is an excellent adsorbent for lindane removal in water.

Summary: This study presents a rapid, selective, ultrasensitive, and cost-effective voltammetric method for determining ultra-trace levels of total aluminum. A new nanocomposite sensing platform was developed using glassy carbon electrodes coated with quinalizarin and PtNi nanoparticles. The platform exhibited higher activity and improved sensitivity due to its large surface area and high electrical conductivity. The results showed a linear calibration curve in a wide concentration range, with a low detection limit and good repeatability.

Summary: Thermo-responsive block copolymers have attracted a lot of attention due to their mature synthesis technology, well-defined structure, controllable molecular weight, and easy implementation of their nano-assemblies in water through temperature regulation. Previous reviews have mainly focused on their biomedical applications, but these polymers also show promising potential in temperature-regulated adsorption and/or separation, nanoreactors for green organic synthesis, etc. This review summarizes the recent progress in thermo-responsive assembly in water and highlights the applications of five different thermo-responsive block copolymers beyond the biomedical field.

Summary: This study investigates the degradation of PFBS by gas-phase electrical discharge plasma, and finds that plasma alone is ineffective in degrading PFBS due to its poor hydrophobicity. To overcome this limitation, a surfactant (CTAB) is introduced to transport PFBS to the plasma-liquid interface, where it is concentrated and degraded. The study proposes a mechanistic understanding of the PFAS-CTAB complex formation, transport, and degradation, and shows that surfactant-assisted plasma treatment is a promising technique for destroying short-chain PFAS in contaminated water.

Summary: By using an inductive nonthermal plasma reactor fed with aluminum trichloride and Ar, single-crystal aluminum nanoparticles were synthesized with different reactor conditions affecting properties like oxide shell thickness, particle mono-dispersity, and particle size. Large quantities of Ar relative to AlCl3, short residence times, and high pressures are needed to form 10-20 nm Al particles with low geometric standard deviations.

Summary: The research and development of energy storage systems have become increasingly important due to the growing use of renewable energy sources. In this study, a new design of a thermal energy battery was fabricated and experimentally investigated. The results showed that the charging time of the battery was improved with the increase of flow rate and temperature of the heat transfer fluid, and the addition of aluminum nanoparticles accelerated the charging process by up to 30%.

Summary: We report a liquid metal gallium-aluminum (Ga-Al) composite water splitting reaction, where gallium nanoparticles (Ga NPs) and nanocrystalline aluminum hydroxide [Al(OH)(3)] are generated simultaneously with the coproduction of green H-2 fuel. This reaction occurs under atmospheric conditions without the need for caustic chemicals, electrolysis, reverse osmosis, inert atmosphere, or external energy input.

Summary: A YAG coating was prepared on a titanium alloy using the APS technique, and its microscopic morphology and phase composition were analyzed. The coating was found to be complete, compact, and well-bonded, primarily composed of amorphous YAG as well as YAP, YAM, and other Y-rich composition. The higher crystallinity on the coating surface was caused by continuous heating of the plasma plume. The main crystalline phases in the coating were YAG, YAP, and YAM, contributed by recrystallization of melted YAG particles and un-melted portion of YAG particles.

Summary: This paper describes the principle and application of plasma, particularly focusing on plasma generated in liquids. It discusses the use of liquid phase plasma for water treatment, metal nanoparticle synthesis, visible light-responsive photocatalyst synthesis, energy material synthesis, and hydrogen gas production. The research results demonstrate that various factors, such as plasma discharge conditions, dissolved oxygen concentration, and pH value, can impact the effectiveness of the liquid phase plasma reaction.
