Abstract

Photocatalytic paints have proven to be a promising solution for combating air pollution in urban environments by breaking down harmful pollutants into harmless by-products. These paints interact with meteorological parameters when exposed outdoors, and we have investigated the influence of these parameters on the degradation of the exposed paint. We conducted experiments in a controlled laboratory in which samples of the photocatalytic paint were exposed to different temperatures and humidity levels. Using a standardized test method, we determined the constant reaction rate and analyzed the data to understand the effects of temperature and humidity on photocatalytic efficiency. The results show a significant effect of temperature and humidity on the constant reaction rate. Temperatures from 10°C to 30°C and humidities from 10% to 50% were found to increase the reaction rate, leading to an improvement in photocatalytic efficiency. However, too wide a temperature range (30℃ to 60℃) and too high a humidity (55% to 80%) had a negative effect on the thermal stability of the paint and its long-term durability. Over time, we observed an increasing loss of adhesion and fading of the paint as temperatures and humidity increased, leading to a deterioration of the photocatalytic paint. In summary, while moderate temperatures and humidity improve photocatalytic efficiency, extreme conditions can negatively affect the stability and long-term performance of the paint.

Abstract

Musa paradisiaca (banana) leaves have been extensively used in traditional medicine for the treatment and management of disorders related to oxidative stress, including diabetes, neurodegenerative diseases, and cancer. However, there is limited scientific evidence supporting these claims. This study aimed to evaluate the hepatoprotective and antioxidant properties of Musa paradisiaca leaf extract in albino rats with carbon tetrachloride (CCl₄)-induced liver damage. Fresh leaves of Musa paradisiaca were collected, shade-dried, and extracted using 60% ethanol. Thirty albino rats were randomly assigned to five groups: control, CCl₄-induced, CCl₄ + silymarin (100 mg/kg), CCl₄ + Musa paradisiaca extract (200 mg/kg), and CCl₄ + Musa paradisiaca extract (400 mg/kg). The extract was administered orally, while CCl₄ was given intraperitoneally (IP) to induce liver damage. Phytochemical screening of the extract revealed the presence of alkaloids, saponins, tannins, flavonoids, anthraquinones, and steroids. Liver function biomarkers—alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP)—were analyzed spectrophotometrically. The results indicated that the Musa paradisiaca extract significantly reduced ALT, AST, and ALP levels (p ≤ 0.05) compared to the CCl₄-treated group, demonstrating its hepatoprotective effects. The 400 mg/kg dose exhibited a more pronounced effect, comparable to that of silymarin. These findings provide scientific validation for the traditional use of Musa paradisiaca leaves in managing liver disorders and conditions associated with oxidative stress. Further studies are recommended to isolate and characterize the bioactive compounds responsible for these effects.
