Characterization techniques, including X-ray diffraction (XRD), photoluminescence (PL) spectroscopy, scanning electron microscopy (SEM), and zeta sizer analysis, were employed to elucidate the crystalline structure, optical properties, morphology, and stability of the synthesized materials. The photocatalytic efficacy of the synthesized nanomaterials was rigorously evaluated for the solar-driven photocatalytic removal of methylene blue (MB) dye. Through systematic optimization, an optimal dosage of 3 mg/mL for the La₂O₃/ZnO nanocomposite was identified, demonstrating a significant enhancement in degradation efficiency over ZnO nanoparticles. Under these optimized conditions, the La₂O₃/ZnO catalyst achieved up to 87.71 % removal of MB (initial concentration of 10 mg/L in 100 mL) within 120 min of exposure to natural sunlight. Additionally, under UV irradiation, the MB solution exhibited an exceptional 95.16 % photodegradation, with an estimated rate constant of 0.03224 min⁻¹ after 90 min of treatment with the La₂O₃/ZnO nanocomposite. To further assess the performance and applicability of the photocatalysts, recyclability studies, scavenger studies, and hot filtration tests were conducted, confirming the potential of eco-friendly La₂O₃/ZnO nanocomposites as effective agents for sustainable environmental remediation strategies.

The setups in this work are dilute (1:25 mass ratio of CaCO₃ to HPAM) and concentrated (1:2 mass ratio) colloidal systems, and an incubation of Iceland spar calcite crystal in dilute HPAM solution. UV–Vis absorption, zeta potential, oscillatory rheology in the form of storage modulus (G’), unconfined compression stress (UCS), and atomic force microscopy (AFM) force mapping, reveal positive interactions and increased consolidation with higher HPAM dosage, up to an optimum level. The second part explores the impact of reservoir conditions, namely salinity and temperature, on the consolidating ability of HPAM. Salinity tests indicate a higher polymer dosage requirement under increased salt concentration to maintain optimum CaCO₃ consolidation, while temperature tests show a reduction in peak mechanical strength of consolidated CaCO₃ samples. In the final part, the preservation of the effectiveness of deploying HPAM in reservoir conditions by crosslinking it with silica nanoparticles (SiONP) is explored. The results from G′ and UCS analyses demonstrate that CaCO₃ consolidated by crosslinked HPAM retains peak mechanical strength even when treated with brine and subjected to continuous heating for three days.

These nanofluids combine two kinds of nanostructures (single-wall and multi-wall) and have better energy conversion, cooling, and heat transmission qualities. Because of their tiny size and strength, carbon nanotubes (CNT) are used to increase machinery and components lubrication and boost system energy storage and charging cycle effectiveness of lithium-ion batteries. Therefore, a mathematical model is formulated to study the hydromagnetic CNT hybrid nanofluid mixed convective flow past an elongating porous surface in the occurrence of external heat source, thermal linear radiation, viscous and Joule dissipation. The nanoparticle diameter and interfacial layer effects are explored by incorporating the Gharesim dynamic viscosity model and Hamilton–Crosser thermal conductivity model.

The numerical Runge-Kutta method and shooting procedure are employed to obtain the outcomes. The current study establishes that the liquid momentum is controlled for the slip flow, thus with the slip condition, the amount of retardation is much higher in comparison with the no-slip condition, and the temperature of the hybrid nanofluid has been raised by a greater heat source coefficient and radiation factor.

One way to qualitatively characterize their mass transfer between vapor and aqueous solutions is to measure the relaxation of the interfacial tension, <em>σ</em>, with time, <em>t</em>, under different nonequilibrium initial conditions. This approach is applied in the present work for geraniol and menthol. By means of combining <em>σ</em>(<em>t</em>) data with the respective equilibrium surface tension isotherms, the instantaneous values of the fragrance adsorption, Γ(<em>t</em>), have been determined. Quantitative characterization of the geraniol and menthol mass transfers in the case of adsorption from vapor to aqueous drops is achieved by using a mixed barrier-diffusion model. The obtained values of the rates of adsorption and desorption are compared with those reported in the literature for benzyl acetate, linalool, and citronellol. In the case of evaporation of the volatiles from their saturated aqueous solutions to the ambient atmosphere, the mass transfer is found to be driven both by mixed barrier-diffusion and by convection-enhanced mechanisms – depending on the air humidity. The quantitative description of the evaporation of volatile molecules is modelled theoretically by adsorption rate constants. In order to achieve the reported model representations, complex numerical calculations are implemented. On the other hand, having in mind the cases when one wishes to avoid extensive computational work, we developed a simple semiempirical model suitable for all five studied fragrances. This simplified approach is convenient for the express comparison and characterization of the evaporation rates. The obtained physicochemical parameters related to the evaporation and condensation of volatiles are important for the rigorous modeling of their complex mixed solutions of practical interest.
