Drug release characterized by UV-<i>vis</i> absorption spectra showed an initial quick release followed by a sustained release. The mean cumulative concentration of the PA released either in phosphate buffer solution (pH = 7.4) or in HCl solution (pH = 1.3) with time was fitted well with ExpDec3 model, namely equation C = A₁exp(-t/τ₁) + A₂exp(-t/τ₂) + A₃exp(-t/τ₃) + C₀.

To verify amorphousness, thermal stability, and chemical makeup, MSNPs and NAA-MSNPs were characterized. The antioxidant activity of NAA and NAA-MSNPs was measured using the DPPH method, and spreadability tests were performed. The effects of the gel on the levels of melanin and erythema, sebum production, skin elasticity, moisture content, and facial pores were assessed using noninvasive in vivo tests. Patch tests on human volunteers demonstrated no skin irritation, and a panel test estimated the gel’s seven sensory and functional parameters. NAA-MSNPs showed improved antibacterial and antifungal activity compared to free NAA. SEM images showed spherical MSNPs and trials with human volunteers demonstrated significant improvements in skin parameters, including erythema, melanin index, hydration level, elasticity, sebum production, and facial pores, as illustrated by 3D visioFace imaging. Notably, the NAA-MSNP gel significantly reduced melanin levels by 16% after 12 weeks, enhancing skin hydration and elasticity.

During the chemical vapor deposition process, the uneven diffusion rate of carbon atoms within catalyst particles is determined by preferential deposition on specific crystal planes, leading to the formation of pores on the surface of CNF. The abundant mesopores on the surface of CNF and the three-dimensional scaffold structure can disperse the local current density, provide sufficient ion diffusion pathways, and effectively regulate the deposition behavior of Na metal.

This study developed metal-modified (La and Ni) mesoporous MCM-41 catalysts for the catalytic processes of thermodegradation and fast pyrolysis of sunflower oil. Lanthanum- and nickel-modified on mesoporous molecular sieve (MCM-41) were synthesized in situ by hydrothermal method. The catalysts were characterized by Thermogravimetric analysis (TG), X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier Transform Infrared Spectroscopy (FTIR), Nitrogen adsorption-desorption at 77 K, and Transmission electron microscopy (TEM). The catalysts performance was evaluated by catalytic thermodegradation (Thermal analysis– TG, DTG and DSC) and fast pyrolysis (Pyrolyzer gas chromatography mass spectrometry– Py-GC-MS). Nickel- and Lanthanum-modified MCM-41 by in situ methodology increased the mesopore parameter, exhibiting metal-silica interactions, resulting in Si/Metal mass ratios of 48 and 77, respectively. The catalytic thermodegradation of sunflower oil shows that Ni-MCM-41 is more active than La-MCM-41. Ni-MCM-41 exhibited the highest deoxygenation activity, producing 56.37% hydrocarbons and achieving a 6.50% reduction in oxygenates compared to the thermal process. Both La-MCM-41 and Ni-MCM-41 catalysts showed high hydrocarbons production compared to thermal process, favoring the formation of compounds containing 14 and 17 carbons, respectively.

In this study, titanium and novel niobium-containing pillared magadiites were obtained by a single route, with modifications achieved using pillaring sols from different metal sources, including alkoxides and oxalate. The influence of hydrolysis stabilization of the alkoxide sources was also evaluated. The resulting transition metal-containing magadiites exhibited Ti and Nb sites with distinct coordination environments on the surface and in the bulk regions. Textural properties were altered based on the metal source used in the pillaring sol. The results suggested that titanium was better incorporated through pre-stabilization, considering water and alkali content.

VSM results showed a saturation magnetization of 32.63 emu/g, facilitating easy magnetic recovery.
