“…A pseudo-first-order kinetic and a second-order kinetic model were tested, since both models have been used to describe the photodegradation kinetics of different organic compounds and using several different ceramic particles, e.g., TiO 2 , 47,48) ZnO, 49,50) Fe 3 O 4 51) and SnO 2 . 52) The pseudo-firstorder kinetic model is presented in (eq.

SnO 2 Sb 2 O 3 particles, with various Sb 2 O 3 mole fraction (x) ranging from 0 to 1, have been synthesized by a sol-gel method. Tin oxalate and antimony chloride were used as the metal precursors, water as the solvent, citric acid as the pH modifier, and triethanolamine as a stabilizing agent. The effect of the chemical composition of the synthesized catalyst on the photocatalytic degradation of methylene blue (MB) and methyl orange (MO) was evaluated. It was established that a SnO 2 Sb 2 O 3 (Sb 2 O 3 mole fraction of x = 0.15) catalyst presents a highly oxidative power to degrade a 20 µM MB solution until 98.60%, using a UV lamp of 254 nm and 6 W. The kinetics of the SnO 2 Sb 2 O 3 (x = 0.15) photocatalytic oxidation was monitored as a function of the initial concentration of MO (100, 200, 300, and 400 µM) at different reaction times. It was found that the reaction probably presents a pseudo-first-order kinetic model. The effect of the intensity of the power lamp was studied, finding an increment from 16.32 to 98.42%, for UV lamps of 6 W and 72 and 1200 mW cm ¹2 , respectively. Finally, the effect of temperature (298, 318, 328 and 338 K) was analyzed, and the activation energy from Ea = 7.2 kcal mol ¹1 was determined.

“…In the last few years, kiwi peels extract has been successfully used to fabricate nanoparticles using a cost effective and eco-friendly green method of synthesis. Zinc oxide (ZnO), titanium dioxide (TiO 2 ), and tin oxide (SnO 2 ) nanoparticles (NPs) were prepared by exploiting the polyphenolic component of kiwi peels used as reducing and capping agent for NPs preparation and stabilization [ 9 , 10 , 11 , 12 ].…”

Kiwi fruit samples (Actinidia deliciosa Planch, cv. Hayward) represent a suitable and good source for fibers obtainment as well as for polyphenolic and carotenoid extraction. With this aim, in this study they were submitted to a double phase extraction to separate insoluble fibers by an organic phase containing lipophilic substances and an hydroalcoholic phase containing polyphenols and soluble fibers. Insoluble fibers could be separated by filtration and sent to be micronized and reused. Hydroalcoholic fractions were then furtherly fractionated by solid-phase extraction. Data coming from the color CIEL*a*b* and the HPLC-DAD analyses of the extracts were compared and correlate with those coming from the SPME-GC/MS analysis of either the finely shredded peels or of the extracts. The obtained extracts were also submitted to anti-radical activity evaluation and anti-Candida activity. Results show that all of the obtained residues are value added products. Hypotheses were also made about the nature and the possible recycle of the obtained purified solid residue.

The advent of nanotechnology has been instrumental in the development of new drugs with novel targets. Recently, metallic nanoparticles have emerged as potential candidates to combat the threat of drug-resistant infections. Diabetic foot ulcers (DFUs) are one of the dreadful complications of diabetes mellitus due to the colonization of numerous drug-resistant pathogenic microbes leading to biofilm formation. Biofilms are difficult to treat due to limited penetration and non-specificity of drugs. Therefore, in the current investigation, SnO2 nanoparticles were biosynthesized using Artemisia vulgaris (AvTO-NPs) as a stabilizing agent and were characterized using ultraviolet–visible (UV–vis) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). Furthermore, the efficacy of AvTO-NPs against biofilms and virulence factors of drug-resistant Candida albicans strains isolated from DFUs was assessed. AvTO-NPs displayed minimum inhibitory concentrations (MICs) ranging from 1 mg/mL to 2 mg/mL against four strains of C. albicans. AvTO-NPs significantly inhibited biofilm formation by 54.8%–87%, germ tube formation by 72%–90%, cell surface hydrophobicity by 68.2%–82.8%, and exopolysaccharide (EPS) production by 69%–86.3% in the test strains at respective 1/2xMIC. Biosynthesized NPs were effective in disrupting established mature biofilms of test strains significantly. Elevated levels of reactive oxygen species (ROS) generation in the AvTO-NPs-treated C. albicans could be the possible cause of cell death leading to biofilm inhibition. The useful insights of the present study could be exploited in the current line of treatment to mitigate the threat of biofilm-related persistent DFUs and expedite wound healing.
