Summary: In this study, we utilized solvent vapor annealing as a polymer processing method to condense a large amount of solvent vapors onto thin films of block copolymers, promoting their self-assembly into ordered nanostructures. Atomic force microscopy revealed the successful generation of a periodic lamellar morphology of poly(2-vinylpyridine)-b-polybutadiene and an ordered morphology comprised of hexagonally-packed structures made of poly(2-vinylpyridine)-b-poly(cyclohexyl methacrylate) on solid substrates.

Summary: Hierarchically structured polymeric colloids were rapidly produced by confined self-assembly of bottlebrush random copolymers in evaporative emulsion droplets. The internal structures of the particles developed instantaneously during the early stage of solvent evaporation due to the confinement effect and fast-assembling polymer architecture. Different particle morphologies were achieved by adjusting the volume fraction of copolymers.

Summary: Research indicates that block copolymers with chemically different bottlebrush blocks can self-assemble into nanostructures resembling micelles in selective solvents. The self-consistent field theoretical approach is utilized to predict the relationship between structural parameters of bottlebrush blocks and properties of micelles, including critical micelle concentration. Theoretical predictions suggest that replacing linear blocks with bottlebrush ones of the same polymerization degrees leads to changes in micellar core size and corona extension, as well as an increase in critical micelle concentration, which are in agreement with computer simulation results.

Summary: Intrinsically disordered peptide amphiphiles (IDPAs) are a novel class of synthetic conjugates that self-assemble into dispersed nanoscopic aggregates or ordered mesophases. Sequence variations in the IDPA systems can significantly alter the headgroup conformation and induce phase transitions, and alterations in the peptide sequence can render IDPAs susceptible to enzymatic cleavage and induce enzymatically activated phase transitions.

Summary: The self-assembly potential of new amphiphilic block copolymers containing dextran and a semi-rigid deoxycholic acid-oligoethyleneglycol polyester was evaluated in terms of copolymer composition and self-assembly procedure. Different morphologies and sizes of aggregates were obtained by varying the polymer composition, with longer oligoethyleneglycol leading to smaller micelles and vesicles due to enhanced flexibility of the polyester hydrophobic block. Adjusting parameters allows for obtaining desired aggregate characteristics.

Summary: Nanoscale block copolymer (BCP) self-assembly is used to finely align sub-10-nm-scale nanopatterns along the atomic edge of 2D flakes. The alignment mechanism is explained based on the wetting layer alternation of the BCP film in the presence of intermediate 2D flakes. The highly aligned nanocylinder templates with low roughness levels result in a sub-10-nm-wide graphene nanoribbon (GNR) array with significant switching characteristics.

Summary: Activation of metal oxides by light is a powerful method to modify their surface chemistry for efficient heterogeneous catalysis and gas sensing. However, understanding of the interface chemistry and mechanism restricts the rational design of oxide interfaces for light-activated gas sensing. In this study, the TiOx-assisted photosensitization of In2O3 towards NO2 sensing was investigated to elucidate the detailed mechanism of light-activated surface chemistry at the metal/gas interface. The resulting heterogeneous oxides demonstrated remarkable NO2 sensing performance under light irradiation due to abundant photoexcited electrons and holes that facilitated surface reactions. Moreover, the easy transfer of electrons and holes across the TiOx-In2O3 interface improved the reversibility of sensing kinetics. This study provides mechanistic insight into how surface chemistry of metal oxides can be controlled by light activation, offering an effective approach for designing high-performance gas sensors.

Summary: The FeCo/sulfurized polyacrylonitrile (SPAN) cathode material is synthesized for lithium-sulfur (Li-S) batteries, which shows the existence of Fe-S/Fe and Co-S bonds that benefit the adsorptive and catalytic activities toward lithium polysulfides (LiPSs). The electrolyte concentration is found to play a crucial role in inhibiting the shuttle of LiPSs, with higher concentrations resulting in more contact ion pairs and fewer free solvent molecules. Batteries assembled with high concentration electrolytes exhibit higher specific capacity retention. This work enriches the route to prepare Li-S batteries through rational design of cathode materials and electrolytes.

Summary: The mesoporous silica shell coating the hydrogenolysis nano-catalyst alters the molecular weight distributions of cleaved polymer chains compared to catalysts without a shell. The shell reduces low-valued gaseous products and increases the median molecular weight of the product, enhancing the value of the products for polymer upcycling. The spatial distribution of polystyrene chains in the nanochannels reveals a non-uniform distribution for longer chains.

Summary: Sodium metal (Na) anodes, with high capacity and low electrochemical potential, are considered the most promising anode for high-energy-density sodium batteries. However, uncontrolled Na dendrite growth and unstable solid electrolyte interphase layer (SEI) formation during cycling have led to poor coulombic efficiency and shorter lifespan. This study explores a series of Na-ion conductive alloy-type protective interfaces (Na-In, Na-Bi, Na-Zn, Na-Sn) as artificial SEI layers to address these issues.

Summary: This study investigates the impact of oxidation on magnetic domains in a nanoscale Fe3GeTe2 flake. The researchers observe an increase in the density of skyrmions with partial oxidation and a loss of the magnetic domain structure with complete oxidation. The interfacial interaction between surface antiferromagnetic oxides and the bulk ferromagnetic Fe3GeTe2, as well as the effect of interfacial roughness, are hypothesized to contribute to the increase in Neel skyrmion creation.
