Summary: This study presents a simple approach to synthesize monodisperse ordered L1(0)-FePt NPs with average size 10.7 nm without further annealing or doping the third metal atoms. The use of hexadecyltrimethylammonium chloride (CTAC) is key in inducing the thermodynamic growth of Fe and Pt atoms into the ordered intermetallic structure. The synthesized 10.7 nm L1(0)-FePt NPs exhibit a coercivity of 3.15 kOe and saturation magnetization of 45 emu/g at room temperature, showing the potential for solution phase synthesis of ordered Pt-based intermetallic NPs.

Summary: In this study, a seed-mediated synthesis method for mass production of ultrathin silver nanowires (AgNWs) was reported. The synthesized AgNWs had an average diameter of 17 nm and an aspect ratio of 1000. The method utilized pentatwinned gold dodecahedrons as primitive seeds and Ag nanorods (AgNRs) as secondary seeds. The process eliminated the need for purification and resulted in high purity AgNWs through a simple precipitation process.

Summary: In this study, a series of Pr6O11 catalysts were developed by CTAB-assisted coprecipitation method and their catalytic performances for soot oxidation and NOx adsorption were investigated. The Pr6O11 catalysts exhibited excellent catalytic activities for both soot oxidation and NOx adsorption at low temperature, which was attributed to their relatively large surface area, strong NO oxidation ability, and high intrinsic activity. The presence of NO was found to promote the soot oxidation, and the possible mechanism of the soot oxidation reaction process was explored using in situ DRIFTS.

Summary: We developed an integrated iterative binomial synthesis strategy that enables precise control over the lengths and sequences of conjugated polymers with versatile backbones. This strategy utilizes phenol as a surrogate for aryl bromide, and combines protecting-group-aided iterative synthesis and iterative binomial synthesis.

Summary: This study presents an interfacial synthesis strategy for efficient and controllable synthesis of CsPbBr3 nanorods by inserting Pb2+ into postsynthetic CsBr nanocrystals at the water-hexane interface using vortex method. The approach allows intrinsic separation of water phase from hexane phase, effectively removing excess Pb2+ and other side reaction salts. The resulting CsPbBr3 nanorods possess a clean surface without the need for further purification, making it a promising method for the synthesis of CsPbBr3 nanorods.

Summary: This study demonstrates a method to break the permeability/selectivity tradeoff using supramolecular polymer networks (SPNs) comprising polybenzimidazole (PBI) and dissociable metal salts. By coordinating metal ions and plasticizing with trifluoroacetate anions, the SPNs achieve higher fractional free volumes and lower d-spacing, resulting in increased H-2 permeability and H-2/CO2 selectivity. The SPNs also exhibit superior mechanical properties and stable performance in the presence of water vapor.

Summary: Hollow-structured materials, such as hollow silica nanoshells, have shown promise in thermal insulation due to their ability to interrupt heat transport pathways. In this study, two low-cost methods, gas-phase and liquid-phase synthesis routes, were used to fabricate hollow silica nanoshells. Both methods resulted in amorphous hollow silica with low thermal conductivity, small particle size, thin shell, and low density. Furthermore, hollow silica-fiberglass composite ceramics were successfully fabricated using high shear mechanical mixing, providing robust mechanical elasticity and fire-retardancy while maintaining low thermal conductivity.
