The post-harvest collected leaves, stems, and vines from chayote (Sechium edule), an abundantly cultivated yet largely discarded agro-waste rich in cellulose and lignin, were transformed into activated carbon through KOH, HNO₃, and FeCl₃ treatment. The KOH route yielded a highly microporous structure (BET surface area 1103 m²/g⁻¹; pore volume 0.601 cm³/g), whereas HNO₃ enhanced oxygenated functional groups and FeCl₃ left behind iron species. In batch studies, the materials removed up to 95% of Mn²⁺ ions under favourable conditions. The adsorption process was better explained by

Annona muricata contains flavonoids, phenolic acids, and tannins in its leaves, pulp, and seeds. The current study provided an accurate analytical method for the pharmacologically active components, including glutathione, potassium, and vitamin B6, in soursop fruit samples of soursop using high-performance liquid chromatography and atomic absorption spectrometry. The fruits of the soursop were cleaned, peeled, and sliced into tiny pieces. The juice was

Measurements of BET, pore diameter, XRD and TGA surface area were used to analyze the chitosan and sunflower peel combination surface, boosting the effectiveness of adsorption. Chitosan combined with sunflower husks had a high surface area of 17.533 m2/g and an optimal pore distribution of 2–20 nm, according to surface area study, which improved the adsorption effectiveness. When the methylene blue dye a

In this work, we explore these molecular properties through the lens of graph theory, employing two powerful topological descriptors: the Geometric–Arithmetic (GA) index and the Atom–Bond Connectivity (ABC) index. Rigorous theorems confirm the non-negativity of both indices, with proofs supported by illustrative graph structures. The GA index emphasizes balanced degree
Read MoreThis study examines the effectiveness of Typha domingensis in improving the physico-chemical parameters of untreated sewage water using floating treatment wetlands (FTWs) and provides insight on the accumulation and translocation of heavy metals and nutrients in the plant. The research was conducted utilizing wastewater samples from the sewage treatment plant of Christ University, Central Campus, Bengaluru, India. T. domingensis, a plant known for its phytoremediation potential, was collected from Dodagubbi Lake Bangalore and introduced to FTWs in a controlled experimental setup. The FTW was d
