Summary: In this article, a robust experimental model investigating strong metal-support interactions (SMSI) and their impact on electrocatalytic reactions is reported. The beneficial interactions between Ni0.9O thin film supports and PtNPs in the CO electrooxidation reaction are described. The results show negative shifts of the CO electrooxidation peak potential when Ni0.9O thin films are in contact with Pt55 NPs and Pt140 NPs, and the oxygen evolution reaction (OER) is suppressed only when PtNPs are in contact with Ni0.9O thin films. Density functional theory (DFT) calculations attribute the CO electrooxidation enhancement and OER suppression to changes in binding energies at the NiO(111)/Pt55 NP interface.

Summary: Polymer nanogels, elastic nanospheres with 3D network structure, have shown potential in enhancing oil recovery. However, their dynamic adsorption and desorption in porous media are still not well understood. In this study, we conducted experiments to investigate these processes in sandstones, and found that nanogels exhibited rapid adsorption and desorption, with the adsorption density ranging from 0.083 to 0.435 mg/g. The adsorption of nanogels increased with their concentration, core permeability, and salt concentration. Salinity played a more important role in the desorption process due to strong interaction with sandstones. Adsorption layer thickness ranged from 0.67 to 2.14, indicating multilayered processes.

Summary: This article reviews the mechanisms and kinetics of particle deposition at solid surfaces, focusing on the formation of self-assembled layers with controlled structure and density. The theoretical aspects, including linear transport under flow and diffusion, as well as the analysis of deposition kinetics in non-linear regimes affected by surface blocking, are briefly discussed. Experimental results for micro and nanoparticles are also discussed, along with the stability of layers and the release kinetics of silver particles. The applicability of quartz microbalance measurements for quantitative studies of nanoparticle deposition kinetics is examined. The review also analyzes representative results of virus deposition at abiotic surfaces and the formation of nanoparticle corona at polymer carrier particles. It argues that the results obtained for colloid particles can serve as reliable reference systems for the interpretation of protein and other bioparticle deposition, supporting the idea that simplicity is universal.

Summary: In this study, the adsorption and subsequent desorption of titanium dioxide (nTiO2) and zinc oxide (nZnO) nanoparticles, as well as polyethylene microplastics (MPs), in aquatic media were investigated. The results showed that nZnO had a faster adsorption rate than nTiO2, but nTiO2 had a higher adsorption extent on MPs. The low adsorption of nZnO could be attributed to the partial dissolution of zinc from nZnO, which resulted in soluble zinc complexes not being adsorbed on MPs. The adsorption process was found to be controlled by physisorption for both nTiO2 and nZnO. Meanwhile, the desorption of nTiO2 was low and independent of pH, while the desorption of nZnO was pH-dependent, with a higher desorption rate at a slightly acidic pH. These findings provide insights into the complex interactions and fate of MPs and metal engineered nanoparticles in the aquatic environment.

Summary: This study investigated the deposition kinetics of positively charged prolate spheroid-shaped polymer microparticles on silica and gold sensors using the quartz microbalance (QCM) technique. The frequency and bandwidth shifts of various overtones were measured as a function of time. The results showed a close to unity ratio for all overtones, which was interpreted in terms of the hydrodynamic model. The results obtained from the QCM method were compared with theoretical modeling and showed good quantitative agreement, especially when considering particle slip relative to the ambient oscillating flow. The study highlights the importance of considering hydrodynamic slip effects when interpreting QCM kinetic results for bioparticles, particularly viruses.

Summary: This study assessed the biological activity of tannic acid-prepared silver nanoparticles (TA-AgNPs) on sinonasal pathogens and nasal epithelial cells. The results showed that TA-AgNPs were effective against most pathogens isolated from patients with acute exacerbations of chronic rhinosinusitis (AECRS) at non-toxic concentrations to human cells. However, prolonged exposure to TA-AgNPs increased toxicity to nasal epithelial cells and enabled some pathogens to resist their biocidal action. Sensitivity testing may be necessary before application.

Summary: The aim of this study was to evaluate the effect of negatively charged quasi-spherical silver nanoparticles (AgNPs) and silver ions on the growth, physiological aspects, yield, and resistance of wheat. The results showed that AgNPs and silver ions had negative effects on roots and reduced seedling blight but improved leaf area. In hydroponic treatment, AgNPs reduced with sodium borohydride and trisodium citrate stimulated germination, a-amylase activity, and shoot length. In pot culture, AgNPs improved plant growth, PSII efficiency, heading, and yield-related parameters. The interaction strength of different reactions was TCSB-AgNPs > SHSH-AgNPs > silver ions. TCSB-AgNPs at the lowest concentration had the most favorable effect, indicating their great potential for use in improving wheat cultivation.

Summary: For the first time, this study proposes the combined use of surface-enhanced Raman spectroscopy (SERS), tip-enhanced infrared (TEIRA) nanospectroscopy, and quartz crystal microbalance (QCM) for comprehensive qualitative and quantitative analyses of drug/metal nanocarrier conjugates. The study focuses on erlotinib, a drug used in non-small cell lung cancer therapy, and its interaction with silver nanoparticles (AgNPs) as drug carriers. The results show the strong connection between the drug and the NPs mainly through the phenylacetylene moiety. The QCM is used to prepare an AgNP monolayer and determine the amount of erlotinib molecules immobilized on the metal nanosurface, while TEIRA nanospectroscopy provides ultra-high spatial resolution to identify the drug/AgNP monolayer connection.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
