    Abstract: This research investigates the extraction and carboxymethylation of cellulose from waste pineapple crown leaves to produce carboxymethyl cellulose (CMC). Cellulose was effectively obtained by processing powdered pineapple crown leaves with sodium hydroxide (NaOH) and nitric acid (HNO3) at 90°C, resulting in maximum extraction yields of 51.64 ± 1.33...

    Abstract: Electrical equipment, such as circuit breakers, often encounters operational issues, such as short-circuit failures. These malfunctions can be attributed to the deposition of aerosols containing aluminium oxide (Al2O3), calcium oxide (CaO), ferric oxide (Fe2O3), and silica (SiO2) on the devices. Previous studies have examined the influence of dust ... Show More
