Here, the dissolution rate of green rust at circumneutral pH and about 27 °C was determined from flow-through batch experiments and interpretation of earlier reported dissolution experiments.

However, their practical use has remained a challenge due to their low mechanical strength, poor aqueous stability and high production costs. In this work, we prepared an organic-inorganic protein-based composite film by incorporating vancomycin-loaded halloysite nanotubes (Hal) and bovine serum albumin (BSA) with a facile and biocompatible method. In the composite film, the abundant α-helix structure in BSA was reduced and transformed into a β-sheet-rich phase-transition BSA (PTB), which then interacted with vancomycin-loaded Hal (VHal) through hydrogen bonding to form a cross-linked network structure. Hal can not only reinforce the protein self-assembly via noncovalent interactions to improve the mechanical strength and stability of the protein film, but also act as carriers of antibacterial agents for a sustained drug release system. As a result, the resultant VHal/PTB composite film could completely eliminate <em>Staphylococcus aureus</em> within 30 min and demonstrated excellent biocompatibility. In vivo studies further showed that the composite film could effectively inhibit bacterial infections and accelerate the healing of infected skin wounds in mouse skin, with near-complete wound closure achieved within 12 days.

The results showed that higher dehydration temperatures reduced the extent of rehydration and were correlated with a decrease in layer charge, particularly in smectites exchanged with divalent cations. This was linked to the fixation of small interlayer cations, resulting in the collapse of high-charge layers and, therefore, slower reaction progress. Smectites exhibited fast initial rehydration followed by slow equilibration stage. Under typical laboratory conditions (20 °C, RH = 30 %), 25 % of water was readsorbed within several minutes whereas 90 % - within four hours, emphasizing the necessity to prevent rehydration during experiments to ensure accuracy of various measurements. Regardless of the experimental conditions, reaction profiles were fitted to contraction and 2D/3D diffusion kinetic models. The activation energy for rehydration (∼50–70 kJ/mol) was comparable to that of dehydration, reflecting similar energy barriers in overcoming adsorption/desorption of tightly bound water. Notably, bentonites exhibited rehydration behaviour similar to that of smectites, with the kinetics also influenced by the layer charge of the smectites.

Therefore, studies aimed at expanding the range of applications through the modification of the microstructure of these clay minerals have increasingly attracted scientific attention. The microstructural alteration of kaolinite through high-energy mechanical action can be an interesting method for mineral functionalization, as it leads to an increase in specific surface area and, consequently, the reactivity of the inorganic solid component. For this reason, this study investigated the effectiveness of the mechanical transformation process using high-purity kaolin, characterized before and after the high-energy milling process using XRF, XRD, DTA/TG, PSD, FTIR, and SEM techniques. The results showed that the milling process significantly altered the kaolinitic microstructure, demonstrating a reduction in particle size under the established experimental conditions, reaching D₉₀ ≤ 1 μm.

The results indicated that the extent of Pb²⁺-mobilizing ability of colloids at pH 7.0 was higher than that at pH 5.0, ascribed to more Pb²⁺ adsorbed to the colloids and greater mobility of colloids at higher pH values. Generally, the contribution of colloid size fractions on Pb²⁺ mobility followed the order of (&gt; 2.0 μm) &gt; (&lt; 0.1 μm) &gt; 0.45–1.2 μm &gt; 0.1–0.45 μm ≈ 1.2–2.0 μm, which depended on the colloid size distribution in the effluents (i.e., the larger proportion of fractions exhibited greater contribution to the enhancement of Pb²⁺ mobility in this work). However, the relative contaminant-mobilizing abilities of different colloid size fractions (obtained by normalizing the fraction-facilitated Pb²⁺ breakthrough with the respective fraction breakthrough) increased with the decrease in colloid size, which stemmed from the relatively higher mobility and greater metal-binding capacities of smaller size fractions. Additionally, the differences in the relative contaminant-mobilizing abilities of different fractions decreased with decreasing sand grain sizes (20–40 mesh (0.425–0.85 mm), 40–60 mesh (0.25–0.425 mm), and 60–80 mesh (0.178–0.25 mm)), which was related to the different mobility of the colloid size fractions.
