Qualitative phytochemical screening revealed the presence of alkaloids, saponins, flavonoids, and tannins, all of which are known for their therapeutic properties, including antioxidant, anti-inflammatory, and antimicrobial effects. Antioxidant activity assays, including 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide, lipid peroxidation, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and alkaline DMSO assays, demonstrated concentration-dependent scavenging activity in both extracts, with the methanolic extract generally exhibiting higher antioxidant efficacy. Additionally, the methanolic extract displayed superior lipid peroxidation inhibition, particularly in egg lecithin assays, indicating its potential to prevent oxidative damage. The antimicrobial assessment showed the aqueous extract had significant inhibitory effects on gram-positive bacteria (Bacillus subtilis and Streptococcus aureus) and selected fungi (Aspergillus niger and Candida albicans), outperforming the methanolic extract. The minimum inhibitory concentration (MIC) was determined through a twofold serial dilution method. Cytotoxicity was assessed using A549 and Hep G2 cell lines, revealing significant cell viability reduction in both cancer cell lines.

In this study, three-dimensional (3D) numerical simulations were conducted to investigate the behavior of droplets in a hydrophilic microchannel. With a hydrophilic microchannel, both wetting characteristics and microchannel geometry play a significant role in influencing the motion and behavior of droplets. The research introduces various droplet behavior regimes influenced by the contact angle (θ), capillary number (Ca), and viscosity ratio (λ), demonstrating that the influence of the hydrophilic microchannel occurs only at low capillary numbers. A predictive model for the critical capillary number to transition between contact and non-contact behaviors with the microchannel surface is proposed, described as follows: (Ca>fleft(lambda right)({a}_{1}C+{a}_{2})).

The operating parameters for the synthesis of FeS2-NPs, including surfactant concentration, temperature, time, and sulfur concentration, were investigated.

PDK is the solid residue generated during the aluminum sulfate manufacturing process. The synthesized Faujasite-Na-zeolite was evaluated for its effectiveness in removing methylene blue (MB), a positively charged dye, from contaminated water. The prepared zeolite was characterized using several analytical techniques, including X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The SEM micrographs revealed that the Faujasite possessed a high surface area and spherical crystals of diameters ≤ 1 micron. The efficiency of the synthesized Faujasite Na-zeolite in eliminating the methylene blue (MB) dye from tainted water was assessed. Various factors were tested including; the amount of zeolite added, the initial concentration of the dye, the removal temperature, the solution pH, and the contact period. The results indicated that the adsorption capacity of methylene blue wear (195.6 mg/g) was attained under the following conditions: an initial dye concentration of 0.1 g/L, a temperature of 55 °C, a contact period of 4 h, and a pH of 10. The adsorption data were analyzed using many isothermal models, including the Freundlich, Langmuir, and Temkin models. The findings suggested that the adsorption process is best fitted by the Freundlich isotherm model. Additionally, the kinetics of the adsorption process were investigated by applying pseudo 1st and pseudo 2nd models.
