Summary: This study employs confocal fluorescence microspectroscopy to investigate the diffusion behavior of zinc myoglobin in a single mesoporous silica particle, revealing that intraparticle diffusion is the rate-limiting process. Diffusion coefficients for distribution and release processes are determined, where surface diffusion is the main distribution process and the release process involves both pore and surface diffusion. The mass transfer kinetics of zinc myoglobin in the silica particle are well explained based on pore and surface diffusion.

Summary: This study presents an improved design for Pd/Ce-Pr catalysts, showing that the PdO-PrOx interaction in materials with high praseodymium content results in lower activity, while a limited amount of Pr in ceria can lead to a more active catalyst. The simultaneous presence of Pd in its reduced and oxidized forms is a key factor for high activity, and the higher hydrophobicity of the sample significantly reduces the H2O inhibition effect typical of Pd-based materials.

Results showed that changes in pore size have a significant effect on catalyst activity and durability, with larger-pore-size catalysts deactivating more rapidly. The presence of SO3H groups on the external surface and reduced pore clogging were identified as factors contributing to the increased reusability of smaller-pore-size catalysts.

Summary: Heterogenisation of homogeneous catalysts onto solid supports is a potential strategy for recyclable and reuseable catalysis. However, immobilised catalysts usually exhibit lower activity compared to their homogeneous counterparts. In this study, the influence of support and solvent on the catalytic activity of heterogenised catalysts in the H-transfer reduction of propionaldehyde was investigated. The results showed that the choice of support does not significantly affect catalytic activity, but solvents with high affinity for the catalyst surface or solvation effects that hinder access to active sites result in lower activity. Molecular dynamics simulations provided insights into the solvation effects involved in the reactions, which play a crucial role in determining the catalytic behavior. The activity of the heterogenised catalysts was found to be comparable to the homogeneous catalysts, indicating that immobilisation of the homogeneous catalyst onto solid supports is a viable and effective strategy for this type of reaction.

Summary: Emulsions are widely used in various consumer products and studying their microscopic behavior is challenging. This study investigates the effect of surfactant concentration on the microstructure and diffusion within water-in-oil emulsion systems using low-field pulsed-field gradient (PFG) NMR and optical imaging. The results show that high surfactant concentration leads to smaller droplets and restricted diffusion near the droplet boundaries, while decreasing surfactant concentration results in larger droplets and less pronounced diffusion components.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
