Summary: A targeted and controlled delivery of molecular surfactants at oil-water interfaces is achieved by the directed assembly of nanoparticles. The assembly of positively charged polystyrene nanoparticles at the oil-water interface is facilitated by the introduction of carboxylic acid groups in the oil phase. The presence of the nanoparticles lowers the stiffness of the water-oil interface and reduces interfacial adhesion. The nanoparticles can release a previously loaded cargo of surfactant molecules, leading to the formation of a finer oil-water emulsion.

Summary: This study reports the magnetic field-induced self-assembly of a conjugated block copolymer and iron oxide nanoparticles at the air-water interface. The magnetic field significantly improves the degree of order, resulting in long-range ordered nanoarrays of the polymer and nanoparticles. The size of the nanoparticles plays a crucial role in the formation of an ordered assembly structure at the nanometer scale.

Summary: The electrodes with a periodic matrix of gold particles patterned by titanium dimples and modified by 3-mercaptopropionic acid (MPA) followed by CD147 receptor grafting were studied for specific impedimetric detection of SARS-CoV-2 viral spike proteins. The study revealed that MPA adsorption on the Au-Ti surface had preferential and stronger binding patterns with CD147, resulting in enhanced surface coverage. Control of bonding at the surface was crucial for oriented receptor assembling and boosted sensitivity. The method has been demonstrated for detecting the SARS virus and can be applied to protein-antigen systems.

Summary: Trapping surface-functionalized faceted nanoparticles at fluid-fluid interfaces can control particle orientation and facilitate their assembly into unique one- and two-dimensional superstructures. By tuning the graft density and differences in miscibility, nanocubes can be induced into different orientations. These orientationally constrained nanocubes can assemble into various unusual structures, which have potential applications in plasmonics, optics, catalysis, and membranes.

Summary: High-activity cobalt-doped alpha-MnO2 hybrid materials were synthesized using the citric acid oxidation reduction (CR) technique and utilized for the catalytic oxidation of toluene. Compared to traditional methods, the microstructure of the Mn-Co bimetallic oxide catalyst can be more easily controlled with better dispersion of active phase. In-depth characterization techniques confirmed that the excellent catalytic performance of CR-Mn10Co1 can be attributed to its large specific surface area, outstanding oxidation reduction ability, and abundant Mn3+ species and oxygen vacancy content. Thus, CR provides a convenient and effective route for the low-cost synthesis of Mn-Co catalysts for VOC removal.

Summary: The study investigated the adsorption process of sunflower protein extract at two air-water and oil-water interfaces, revealing a three-step mechanism. Initially, a diffusion-limited adsorption of proteins at interfaces occurs, followed by the formation of a three-dimensional saturated monolayer of proteins, and finally a thick layer expanding in the aqueous phase. The study also found that the adsorption mechanisms of proteins exhibit significant divergences at longer adsorption times.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: In this study, carbon nanobracelets, which are cyclic molecules composed of alternating polycyclic regions and double carbon chains, were investigated using spin-polarized density functional theory. The results show that carbon nanobracelets with odd number of monomers exhibit distinct electronic energy levels, band gaps, and carbon chain deformation compared to those with even number of monomers.

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.

Summary: Drug-loaded cellulose diacetate (CDA) membranes were prepared using different compositions of mixed solvent. The microstructure and performance of the membranes were investigated, and a method to predict drug release properties was proposed. The results showed that the composition of the mixed solvent significantly affected the overall performance of CDA membranes, and the release rates of drugs were related to Δdelta and the intrinsic viscosity of CDA.
