“…Accordingly, the impact of various parameters on the catalytic reduction reaction of pollutants by MNPs@Alg/BP with the reducing agent (NaBH 4 ) was further studied. The performance of the prepared Cu@Alg/BP was also compared with other catalysts reported in the literature for catalyzed reduction of MO in the presence of NaBH 4 , as revealed in Table 1 [ 25 , 26 , 27 , 28 , 29 , 30 ].…”

Water pollution is considered a perilous issue that requires an immediate solution. This is largely because of the strong correlation between the global population increase and the amount of waste produced (most notably food waste). This project prompts the conversion of food waste into useful materials that can be used with sodium alginate as a catalytic support for metal nanoparticles. Sodium alginate/banana peel (Alg/BP) beads were prepared simply using an eco-friendly method. The prepared materials were modified using nanostructured materials to enhance their characteristics. Alg/BP beads were employed as adsorbents for metals that were then treated with sodium borohydride to produce MNPs@Alg/BP. Different MNPs@Alg/BP (MNPs = Ag, Ni, Co, Fe, and Cu) were used as catalysts for reducing 4-nitrophenol (4-NP) by NaBH4 to evaluate each catalyst performance in a model reaction. The results exhibited that Cu@Alg/BP was most efficient toward complete transformation of 4-NP. Therefore, Cu@Alg/BP was also used as a catalyst for the reduction of potassium ferricyanide, congo red, methyl orange (MO), and methylene blue. It was found that Cu@Alg/BP beads catalytically reduced up to 95–99% of above pollutants within a few minutes. Cu@Alg/BP beads were more selective in reducing MO among the pollutants. The catalytic activity of Cu@Alg/BP was examined by evaluating the impact of numerous parameters on MO reduction. The results are expected to provide a new strategy for the removal of inorganic and organic water contaminants based on efficient and low-cost catalysts.

Nano-silver technology for cosmetics preparation is quite popular in recent times because nano-silver is non-toxic and has good antibacterial properties used to create products for skin protection purposes. This studyinvestigated the preparation of a cream product that brings a moisturizing effect with hyaluronic acid and antibacterial effects with nano-silver extracted from natural, environmentally friendly passion fruit peels. The product not only meets the market demand but also brings outstanding efficiency in the application of the antibacterial properties of nano-silver to users. This study investigates the excipient ingredients to preparea complete formula cream containing nano-silver with antibacterial and skin moisturizing properties. The nano-silver lotion formula was developed by evaluating the ability of excipient emulsions including oil phase - water phase excipients, emulsifying excipients, excipients with moisturizing effect, and the ratio of nano-silver.After that, the cream was evaluated for sensory, pH, skin irritation, moisturizing ability, and antibacterial ability on some strains of bacteria. The study was success in preparing a moisturizer containing nano-silver synthesized from passion fruit peel extract, satisfying the properties of a cosmetic product and encouraging further research.

Extraction methods directly affect pectin extraction yield and physicochemical and structural characteristics. The effects of acid extraction (AE), ultrasonic-assisted acid extraction (UA), steam explosion pretreatment combined with acid extraction (SEA) and ultrasonic-assisted SEA (USEA) on the yield, structure, and properties of passion fruit pectin were studied. The pectin yield of UA was 6.5%, equivalent to that of AE at 60 min (5.3%), but the emulsion stability of UA pectin was poor. The pectin obtained by USEA improved emulsion stability. Compared with UA, it had higher protein content (0.62%), rhamnogalacturonan I (18.44%) and lower molecular weight (0.72 × 105 Da). In addition, SEA and USEA had high pectin extraction yields (9.9% and 10.7%) and the pectin obtained from them had lower degrees of esterification (59.3% and 68.5%), but poor thermal stability. The results showed that ultrasonic-assisted steam explosion pretreatment combined with acid extraction is a high-efficiency and high-yield method. This method obtains pectin with good emulsifying stability from passion fruit peel.
