Summary: In this study, a feasible method for the preparation of lignin-based carbon nanotubes (L-CNTs) using lignin as the carbon source based on mobile chemical vapor deposition is proposed. Lignin-based micelles were used as a soft template to prepare a catalyst, and then L-CNTs were synthesized from gaseous products generated by lignin pyrolysis. By adjusting the reaction conditions, L-CNTs with diameters ranging from 10 to 110 nm and lengths ranging from 1 to 6 & mu;m were obtained. The synthesized L-CNTs were mainly multi-walled carbon nanotubes, of which the crystal layer spacing was 0.35 nm, with a good graphitization degree and thermal stability, providing a new method for the high-value utilization of lignin.

Summary: Lipid oxidation is a major cause of quality deterioration in food products, and the presence of colloidal structures and interfaces play a crucial role in this process. Micelles in emulsions and reverse micelles in bulk oils are reservoirs for antioxidants and pro-oxidants, and serve as nanoreactors where lipid oxidation reactions occur.

Summary: The ABA triblock copolymer nanoparticles of PHPMA-b-PS-b-PHPMA with a hydrophobic core of PS and a hydrophilic corona of PHPMA were synthesized by dispersion RAFT polymerization. It was found that these nanoparticles have a larger diameter and higher chain density compared to similar PHPMA-b-PS diblock copolymer nanoparticles, making them efficient emulsifiers that can decrease interfacial tension.

Summary: This study presents a versatile method for forming dendrimer superstructures using coacervate-core micelles as templates, resulting in well-defined covalently cross-linked nanostructures called dendroids. By incorporating dendrimer-encapsulated gold nanoparticles into the micelle template, stable three-dimensional structures are formed, illustrating the potential for various classes of supermolecules in different research areas.

Summary: Based on the flat-plate formalism, this paper presents an analytical theory for electrophoresis of soft particles with a hydrophobic inner core decorated with a layer of polymer segments. By adopting the soft-step function, the chemical and structural anisotropy of the peripheral polyelectrolyte layer is modeled, considering the ion partitioning effect. A general expression for electrophoretic mobility is derived, considering the impacts of inner core hydrophobicity, inhomogeneous segment distribution, and ion partitioning effect. Asymptotic limits are also derived under various electrostatic and hydrodynamic conditions.

Summary: In this study, polyaniline/poly(styrene sulfonate) (PANI/PSS) nanocomposite and polyaniline center dot silver (PANI center dot Ag) nanohybrid thin films were successfully prepared for gas sensing of sexual pheromones from the neotropical brown stink bug. Both nanosensors showed similar sensitivities, but the PANI center dot Ag nanohybrid nanosensor had a lower limit of detection, making it a promising candidate for the detection of sexual pheromones. UV-vis and FTIR analysis confirmed the incorporation of Ag nanoparticles in the nanohybrid sensing layer, which contributed to the improved detection performance.

Summary: We report on Prussian Blue based nanozymes comparable in size with a natural enzyme. Protein-sized nanoparticles have been synthesized as templates in reversed micelles, and their catalytic activity has been studied. Hydrogen peroxide sensors made with these nanozymes showed higher sensitivity. Therefore, protein-sized nanozymes have important applications in sensors and analytical kits.

Summary: This study proposes a method of soft templating using self-assembly of conducting monomers in organic solvents to form porous nanotubular structures. Results show that NaphDOT is capable of forming vertically aligned nanotubes, and the size of micelles in the polymerization solution correlates with the inner diameter of the nanotubes formed.
