“…In the control system, S1—pretreated CTW weight loss was recorded as 0.109 ± 0.04 mg, S2—EO-treated CTW weight loss was 0.98 ± 0.06 mg, S3—PO-treated CTW weight loss was 0.64 ± 0.03 mg, and S4—PEO-treated CTW weight loss was 0.33 ± 0.05. The corrosion rate on exposure in S1, S2, S3, and S4 was 1.970, 0.859, 0.566, and 0.249, respectively (AlSalhi et al, 2023 ). After analyzing the statistical variance, it was found that the corrosion rate result, p < 0.05, is statistically significant.…”

BackgroundCooling towers are specialized heat exchanger devices in which air and water interact closely to cool the water's temperature. However, the cooling water contains organic nutrients that can cause microbial corrosion (MC) on the metal surfaces of the tower. This research explores the combined wastewater treatment approach using electrochemical-oxidation (EO), photo-oxidation (PO), and photoelectrochemical oxidation (PEO) to contain pollutants and prevent MC.MethodsThe study employed electro-oxidation, a process involving direct current (DC) power supply, to degrade wastewater. MC studies were conducted using weight loss assessments, scanning electron microscopy (SEM), and x-ray diffraction (XRD).ResultsAfter wastewater is subjected to electro-oxidation for 4 h, a notable decrease in pollutants was observed, with degradation efficiencies of 71, 75, and 96%, respectively. In the wastewater treated by PEO, microbial growth is restricted as the chemical oxygen demand decreases.DiscussionA metagenomics study revealed that bacteria present in the cooling tower water consists of 12% of Nitrospira genus and 22% of Fusobacterium genus. Conclusively, PEO serves as an effective method for treating wastewater, inhibiting microbial growth, degrading pollutants, and protecting metal from biocorrosion.

“…The administration of avocado fruit extract topically to rat wound models has been demonstrated to improve healing times and raise levels of the structural protein hydroxyproline, according to research [153]. It has also been demonstrated that administering avocado oil topically to rats throughout the WH process leads to an increase in collagen synthesis and a reduction in the total number of inflammatory cells [154,155].…”

The cosmetics industry has been forced to search for new active chemicals as a result of increasing customer demand as well as stricter international regulations. Botanical extract offers a source of new active chemicals that is nearly endless and may be used to make cosmetics. Due to their olfactory character in the creation of fragrances and perfumes and the many beneficial properties of their individual components (EOCs), essential oils (EOs) are becoming increasingly popular natural ingredients in the cosmetics and toiletries industry. These properties include anti-inflammatory, antimicrobial, and antioxidant properties (e.g., moisturizers, lotions and cleanser in skin care cosmetics; conditioners, masks or antidandruff products in hair care products; lipsticks, or fragrances in perfumery). It is difficult to generalise the possible applications of essential oils in cosmetics and toiletries because each essential oil has its own unique chemical profile, which is connected with its own particular collection of benefits. Instead, formulators need to make an effort to discover acceptable mixes of essential oils or essential oil compounds in order to get the results they want from the completed goods. This paper presents a detailed examination of the existing research on the usage of essential oils and essential oil compounds (EOs and EOCs) in the cosmetics sector. In addition, we will focus on a few critical topics regarding the safety of essential oils and essential oil compounds used in the cosmetics sector. When formulators of cosmetics are working to perfect products that are based on botanical extracts, they are very likely to find the information offered in this review to be valuable.

“…There are similarities between the H 2 S removal by the oxygen injection and air pressurization, as described by and . These methods have the advantages of organic matter obliteration, acidic gas control, and environmentally friendly treatment [11][12][13][14]. Air injection is easily used in sewer systems but interferes with the efficiency of the oxygen transfer [15,16].…”

Hydrogen sulfide (H2S) generated in sewer systems is problematic to public health and the environment, owing to its corrosive consequences, odor concerns, and poison control issues. In a previous work, conductive concrete, based on amorphous carbon with a mechanism that operates as a microbial fuel cell was investigated. The objective of the present study is to develop additional materials for highly conductive concrete, to mitigate the concentration of H2S in sewer pipes. Adsorption experiments were conducted to elucidate the role of the H2S reduction. Additionally, electricity-producing bacteria (EPB), isolated from a municipal wastewater treatment plant, were inoculated to improve the H2S reduction. The experimental results showed that inoculation with EPB could decrease the concentration of H2S, indicating that H2S was biologically oxidized by EPB. Several types of new materials containing acetylene black, or magnetite were discovered for use as conductive concrete, and their abilities to enhance the biological oxidation of H2S were evaluated. These conductive concretes were more effective than the commercial conductive concrete, based on amorphous carbon, in decreasing the H2S concentration in sewer pipes.
