Summary: This work focuses on the hydrogen production from sodium borohydride (NaBH4) hydrolysis using homogeneous copper ferrite (CuFe2O4) nanocubes. The nanocubes, produced without the use of surfactants, exhibited good catalytic activity and recyclability in the hydrolysis process. The hydrogen production rate reached up to 1.5 L/min/g at 303K, which is significantly higher than other CuFe2O4 materials. The effects of NaOH concentration, NaBH4 concentration, and reaction temperature were investigated, and the nanocubes were found to have a low activation energy of 41.53 kJ/mol.

Summary: Oxidation of alpha-siloxy thioethers results in the formation of unstable sulfoxides, which then undergo intramolecular oxygen-to-oxygen silyl migration to break the C-S linkage, producing silyl protected sulfenic acids and thiosulfinates. This process is utilized for developing oxidation-triggered allicin donors.

Summary: In this study, 2D CsPbBr3 nanosheets with a thickness of about 3 nm were successfully synthesized, and their lateral dimensions were found to be adjustable by tuning the ratio of short and long ligands. The nanosheets resulted from the self-assembly of CsPbBr3 nanocubes, with a narrow amorphous region between adjacent nanocubes. Insights into the structure and growth mechanism of these nanosheets were obtained through microstructural characterizations and theoretical calculations.

Summary: The synthesis of mesoporous silica nanoparticles (MSNs) for nanomedicine applications is influenced by various experimental factors and lacks reproducibility. This study used pH measurements and light diffusion monitoring to investigate the early stages of MSNs synthesis. The results revealed two hydrolysis regimes before nanoparticle formation, and the condensation reaction only initiated after silicate-surfactant micelle aggregation. Factors like stirring strength and presence of sodium hydroxide carbonates significantly affected the kinetics and size of MSNs formation, requiring careful control for reproducibility. The study proposed a formation mechanism that emphasized the interplay between chemical and physicochemical processes in this complex system.

Summary: The moisture content on iron mineral surfaces plays a crucial role in catalyzing the hydrolysis of antibiotics; competition of water molecules for reactive sites can inhibit the hydrolytic reaction when the surface water content exceeds 10 wt %. Iron oxides exhibit efficient catalytic performance for antibiotic hydrolysis under limited moisture conditions, with distinctive catalytic processes depending on surface properties.

Summary: This study investigated the influence of soy protein and its hydrolysates on the formation of different types of heterocyclic aromatic amines (HAAs) in roasted pork. The results showed that 7S and its hydrolysates inhibited the formation of quinoxaline HAAs, while promoting the formation of pyridine and β-carboline HAAs. The inhibitory effect on quinoxaline HAAs was likely due to DPPH radical scavenging capacity, while the promotive effect on other HAAs could be attributed to the presence of free amino acids and reactive carbonyls. This research provides recommendations for the application of soy protein in high-temperature meat products.

Summary: Reverse flotation desilication using anionic collector sodium oleate and activator Ca2+ is an effective method for purifying hematite. This study systematically investigated the separation mechanism of hematite and quartz, considering the effect of surface hydroxylation. Experimental results showed that the success of anionic reverse flotation of hematite relied on the activation of quartz by Ca2+ and the selective inhibition of hematite by sodium humate. The use of DFT calculations and SEM analysis confirmed the adsorption and chemisorption processes on the surfaces of quartz and hematite, respectively.

Summary: The study investigates the influence of external magnetic fields on the anisotropic collective dynamics of core/shell colloidal cubes with hematite cores and silica shells. Results show that these micrometer-sized particles self-assemble into chains and sediment to form higher-order structures, with dynamics following compressed exponential behavior in different directions with respect to the external field, indicating hyperdiffusive behavior. The anomalous dynamics are believed to be caused by the inhomogeneous distribution of stress points resulting from external field-induced alignment of chains.

Summary: Our study investigates the influence of an external magnetic field on the self-assembly of hematite-silica core-shell prolate colloids, revealing a counterintuitive phenomenon where prolate colloids self-assemble into oblate liquid crystalline phases. We found that the formation of this unusual sequence of field-induced structures is dictated not only by the aspect ratio, but also by subtle deviations from the ideal ellipsoidal shape. This study demonstrates the importance of particle shape in the field-directed self-assembly of colloidal structures.

Summary: Studying the diffusion of proteins in cells is essential for understanding biological mechanisms. X-ray photon correlation spectroscopy (XPCS) is currently the only method to study long-time collective diffusion on the scale of proteins, but its application in biological systems has been limited due to radiation damage. In this study, a new approach using XPCS to measure cage relaxation in crowded α-crystallin solutions was applied, allowing for correction of radiation effects, obtaining missing information on long-time diffusion, and supporting the fundamental analogy between protein and colloid dynamical arrest.

Summary: Monoclonal antibody solutions have the potential to become an important therapeutic tool in the future. However, formulating stable solutions suitable for patient self-administration presents challenges due to viscosity increase at high concentrations. Through the characterization of clusters, we establish a link between microscopic molecular details and the properties of antibody solutions. Our findings provide insights into the self-assembly of monoclonal antibodies, which can guide the formulation of stable and effective solutions.

Summary: This study investigated the influence of microgel particle structure on phase behavior and validated the proposed interaction potential by synthesizing and characterizing four sets of ionic microgels with varying crosslinker density. The results demonstrated that the microgel architecture plays a key role in phase behavior, with dangling ends driving phase transitions and interactions at low concentrations. Comparison to theory highlighted the need for a refined theoretical model that considers these close-contact interactions.

Summary: Anisotropic particles exhibit richer and more complex phase behavior compared to their spherical counterparts, with dynamic behavior being a relatively less explored area. Using USA-XPCS, this study systematically investigates the structural and dynamic properties of colloidal ellipsoids at the nearest-neighbor length scale. Results reveal a scaling behavior of the effective long time diffusion coefficient with the effective structure factor, providing insight into the effective amplitude function and the volume fraction corresponding to the arrest transition.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
