Summary: Biomolecular self-assembly is a fundamental process used by life to create functional materials, but progress in engineering self-assembly at solid-liquid interfaces lags behind that in bulk solutions. Recent research has focused on programming self-assembly of peptides, proteins, and peptoids at solid-liquid interfaces, as well as advancing physical understandings of self-assembly pathways using in situ atomic force microscopy. These developments are leading to novel strategies for designing biomaterials organized at and interfaced with inorganic surfaces.

Summary: In this study, it was found that the presence of micro/nanostructured surfaces significantly affects the evaporation rate of droplets, with the wettability and volume of the droplets further influencing this effect. Theoretical and experimental results showed agreement when the scale of the solid-liquid-vapor interface (slv) was negligible. For microstructured surfaces, the scale of the slv interface could reach 253-940 μm, and the evaporation rate at the slv interface accounted for 16-48% of the total evaporation rate. The scale and rate of the slv interface increased with a decrease in the initial contact angle or an increase in the droplet volume. These findings are important for practical engineering and medical applications involving droplet evaporation on micro/nanostructured surfaces.

Summary: Alkyl ether carboxylate surfactants at the alkane-water interface were studied experimentally and through molecular dynamics simulations. The experimental results were well interpreted with the Redlich-Peterson adsorption model and showed agreement with published data on other surfactants. The length of the ethylene oxide hydrophilic segment had a significant impact on the critical micelle concentration and the interfacial tension at the critical micelle concentration. The simulations showed semi-quantitative agreement with the experiments and revealed general tendencies related to the surfactant interactions.

Summary: The solid-liquid equilibria of four binary mixtures of 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ionic liquids with varying alkyl substituent lengths were studied. Eutectic behavior was observed in systems with long alkyl substituents (14-18 carbon atoms), while a non-eutectic system was found in a binary mixture with ethyl and octadecyl substituents. The experimentally determined eutectic compositions closely matched those predicted by the Schrodervan Laar equation, with a significant decrease in melting temperature compared to the parent ionic liquids.

Summary: Self-assembly is a fundamental tool for constructing materials. Copillar[5]arenes, driven by CH center dot center dot center dot 7r interactions, are optimal models for building heteroditopic monomers. The self-assembly manner of copillar[5]arenes in the solid state depends on the competition between the pillar[5]arene cavity and the threading guest moiety or solvent molecules.

Summary: The self-assembled material stabilized by halogen bonding, m-BrTBE, forms uniform ball-like aggregates with high photoluminescence quantum yield, showing a more red-shifted emission compared to TBE. The enhanced AIE behavior is attributed to the important effect of meta-bromide substituents, promoting radiative processes and blocking nonradiative relaxation pathways.

Summary: Fabricating tetraphenylethylene (TPE)-functionalized metal-organic frameworks (MOFs) on surfaces and understanding the growth mechanism were investigated. TPE molecules formed self-assembled patterns on Au(111) surface at 298 K. Stepwise annealing led to the formation of surface-stabilized radicals and metal-organic networks. By replacing the substrate with Cu(111), more ordered MOFs were obtained due to the higher catalytic activity.

Summary: In order to obtain dendrite-free zinc-ion batteries, a theoretically guided Zn2+ confining-anchoring strategy is proposed based on the different strengths between the alpha-cyclodextrin (& alpha;-CD) additive and various crystallographic planes of zinc. The strategy enables the preferential growth of Zn2+ ions along the (002) plane of zinc, suppressing dendrite growth and improving battery performance. With alpha-CD additives, the zinc anode exhibits exceptional cumulative capacity and high coulombic efficiency, demonstrating its potential for practical applications.

Summary: Shape persistent macrocycles (SPMs) consisting of a π-conjugated backbone and flexible side chains have shown promising potential in generating interesting self-assembly nanopatterns and acting as templates to trap guest molecules on a 2D surface. In this study, an oval six-membered macrocycle (M1) with specific linkers was designed and synthesized. The self-assembly behavior and interaction with guest molecules on a graphite surface were investigated using scanning tunneling microscopy (STM). The results showed that M1 molecules formed three ordered macrocyclic patterns which selectively trapped triphenylene (Tp) and pyrene (Py) molecules. Molecular mechanics (MM) simulations were also utilized to further understand the formation mechanism and adsorption stability of the host-guest nanopatterns on the graphite surface.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
