“…The XRD diffractograms show the presence of minerals such as Freedite (Pb 8 Cu(AsO 3 ) 2 O 3 Cl 5 ) and Jalpaite (Ag 3 CuS 2 ). The presence of silver (Ag), copper (Cu), and Cl (chlorine) elicit anti-bacterial characteristics of F. benghalensis, which is further validated in the anti-bacterial study [9,47,48].…”

Conventional coagulation techniques have shown inefficacy for the removal of DBPs precursor i.e. hydrophobic NOM. The present study has used a bio-flocculant named Ficus benghalensis to enhance the coagulation activity of alum for the removal of hydrophobic NOM. The coagulation activity of the augmented treatment (Alum-F. benghalensis) system was validated using spectroscopic analysis. The augmented system had shown an increment in DOC and A254 removal by ~30% and ~16%, respectively. ASI and A272 had shown a continual decrease (from 0.12 to 0.08 and 0.46 to 0.23, respectively) for the augmented system. Chlorine demand was found lesser for the augmented system (1.4 mg/L) compared to alum (1.55 mg/L) only. The augmented system had shown a drastic reduction (from 0.1459 to 0.0638) in the value of (-∆A272), which is directly related to the reduction in THMFP. The combined effects of sweep coagulation and charge neutralization were the responsible mechanisms for the augmented coagulation system. The noteworthy anti-bacterial activity of F. benghalensis was observed due to the presence of silver, copper, and traces of chlorine in its structure. Thus, the proposed augmented coagulation system can be used to remove the hydrophobic NOM from the water.

[4][5][6][7][8][9] In order to improve the performance of the application fields above utilizing CuS, it is essential to maximize the specific surface area through the nanonization of CuS. For example, photothermal conversion, one of the attractive properties of CuS, is possible because surface free electrons oscillate collectively due to localized surface plasmon resonance with near-infrared (NIR) rays incident on the surface of nanosized CuS.…”

Copper sulfide (CuS), a copper‐deficient p‐type semiconductor material, has been widely utilized due to its unique optical properties, low toxicity, and cost‐effectiveness. Although many studies have been conducted on synthesizing CuS nanoparticles, harsh synthetic conditions and low yield must be solved. This study presents a new methodology that can synthesize CuS nanoparticles in large quantities at room temperature and pressure using high‐concentration Cu complex ion precursors. This methodology is based on the theory that the critical nucleus radius and the critical nucleation free energy decrease as the concentration of the precursor increases to synthesize a large number of nanoparticles by applying low energy. In addition, it is possible to minimize the aggregation of nanoparticles, which is a problem of nanoparticles synthesized at a high precursor concentration through complex ions in the solution. We synthesized nanoparticles by controlling the precursor concentration from 0.1 to 2.5 M to confirm the effect of the precursor concentration on the size, shape, and yield of nanoparticles. As the precursor concentration increased, the particle size decreased, and the yield improved. The CuS nanoparticles synthesized at the highest concentration had a size of about 17 nm without a strong agglomeration and a yield of about 213.9 g/L. Furthermore, the nanoparticles showed excellent photothermal performance due to their high near‐infrared absorption. When about 0.1 g of the nanoparticles were irradiated with a Xenon lamp and an 808 nm laser, the maximum temperatures and rising rates were 53.7°C and 172.1°C and 13.8°C/mg and 33°C/mg, respectively. The excellent photothermal properties of CuS nanoparticles suggest the potential of this material for various applications.
