The adsorption experiments of bromocresol green dye on alumina/talc nanocomposite were designed and performed based on the design of experiment software by response surface method and central cube design. In the design of experiments, factors including pH, initial concentration of bromocresol green, alumina/talc nanocomposite dose, contact time and temperature were investigated.

Among Langmuir, Freundlich and Temkin isotherms, the desired adsorption followed the Langmuir isotherm model with a regression coefficient of 0.9955 and the maximum adsorption capacity of 147.06 mg/g. The thermodynamic investigation of the adsorption process indicated that all three quantities of Gibbs free energy, enthalpy, and entropy changes were negative and therefore, the process was spontaneity, exothermic, and reducing disorder, respectively, especially at 25 °C.

AMP clays containing LP in different drug-to-clay ratios (Losartan Potassium Clay; LPC-1, LPC-2 and LPC-3) resulted in porous organic hybrids for improvement in the bioavailability of LP. Organic clays and LPC-3 were structurally characterized by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy. In-vitro dissolution studies resulted in rapid release of LP from LPC-3 in 2 h compared to other compositions. More than 80% LP was released from LPC-3 after 45 min, and complete release at the end of 3 h. LPC-3 showed a 1.5-fold increase in solubility at pH 1.0 compared to the LP alone. AMP clays drew a change in the pH of an aqueous solution to 6.0, resulting in the dissolution of LP. The cellular uptake showed 74% permeation of LP from LPC-3 across Caco-2 cells. Moreover, in-vivo studies revealed an increase in the peak plasma concentration (C_max), area under the plasma concentration-time curve (AUC_0-24h) and reduction in time to reach the peak plasma concentration (T_max) after an oral administration of LPC-3. Thus, the relative bioavailability of LPC-3 was found to be 1.52-fold increase than LP solution.

A combination of X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), and Vickers microhardness (H_v) testing is employed to assess the impact of Mg incorporation. Experimental and computational results confirm the successful substitution of Mg²⁺ ions into the ZnCoO lattice without forming secondary phases. XRD analyses reveal a slight reduction in crystallite size, varying from 37.62 nm to 36.48 nm, attributable to the differences in ionic radius and electronegativity between Mg²⁺ and Zn²⁺ ions. Mg addition enhances crystallinity, interface state formation, and atomic-scale interactions, while promoting quantum confinement effects. SEM observations indicate that Mg/Zn substitution significantly influences particle size, surface morphology, and oxide layer thickness. Increasing Mg content improves grain coupling and surface uniformity through strengthened interfacial interactions. Microhardness results show that Mg incorporation improves mechanical stability by limiting crack propagation, enhancing grain boundary couplings, and minimizing stored internal strain energy. Magnetic measurements indicate that all samples exhibit predominantly paramagnetic behavior with weak ferromagnetic features emerging at low temperatures. Low-temperature magnetization is attributed to defect-mediated ferromagnetic coupling, whereas high-temperature behavior follows Curie–Weiss paramagnetism. The Mg/Zn substitution alters electronic structure and oxygen vacancy distribution, modulating exchange interactions. Small coercivity values (230 Oe in ZFC and 570 Oe in FC) and vertical M–H loop shifts at 5 K suggest diluted antiferromagnetism rather than conventional exchange bias effects. Additionally, creep analysis from loading–unloading curves confirms that increasing Mg content lowers the creep rate, with the ZnO: Mg (5%) sample exhibiting the best mechanical resilience. In conclusion, Mg substitution significantly enhances the structural, magnetic, and mechanical performance of ZnCoO matrices, making them more favorable for controlled paramagnetic applications than room-temperature spintronic technologies.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div><div><p>Fundamental Structural Properties of Zn_0.95-xMg_xCo_0.05O DMS structure.</p></div></div></figure></div></div>","PeriodicalId":664,"journal":{"name":"Journal of Sol-Gel Science and Technology","volume":"115 3","pages":"1694 - 1714"},"PeriodicalIF":3.2,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
