“…The sharp absorption in the wavelength at 334 nm clarified the basic band absorption of ZnO/CuO crystals because of the electron transitions from the valence band to the conduction band (O2p-3d) associated with the surface plasmon resonance phenomena. In a nanostructure's aspect, the electronic states become completely discrete, as per atoms and molecules (Banik and Basumallick, 2017).…”

Chemical corrosion and bio-corrosion in water pipelines are the most common problem in the industry worldwide which cause damage to expensive equipment and increase the maintenance costs. In the current study, the nanocomposite composed of ZnO and CuO nanoparticles was successfully synthesized using brown algae (Sargassum muticum) extract and then dispersed in polyethylene oxide polymer. The synthesized nanoparticles were exposed to gamma radiation to reduce their particle size. The synthesized nanocomposites were characterized using UV-vis spectroscopy, Dynamic light scattering (DLS), X-ray diffraction (XRD), Transmission electron microscopy (TEM), and FTIR analysis, then, the anti-biofilm and anti-adherence efficacy of nanocomposite were evaluated. The results revealed that gamma radiation reduced the particle size of ZnO and CuO nanoparticles to l5 and 20 nm, respectively. Also, the results showed a significant reduction (P < 0.001) in biofilm formation and adherence of Proteus mirabilis (P. mirabilis), Pseudomonas aeruginosa (P. aeruginosa), and Staphylococcus aureus (S. aureus) to carbon mild steel coupon C1010. In addition, from all the tested strains, P. mirabilis caused the highest bio-corrosion rate 1.5 mpy on mild steel coupon and nanocomposite prevented its adhesion as confirmed by Scanning electron microscope (SEM). Furthermore, the nanocomposite at 150 ppm showed the highest anti-corrosion activity 92.3% in 1 M HCl and exhibited mix-type inhibitor (cathodic and anodic). Finally, the results concluded that the green synthesized nanocomposite had multi-function to be used as anti-biofilm, bio-corrosion inhibitor, and anti-corrosion.

“…Inamuddin et al also recommended the use of organic-inorganic composite exchanger (Mohammad and Inamuddin (2015), Inamuddin (2010) for water purification. Banik and Basumallick 2017; Basumallick and Santra 2017) reported a cost-effective method of removal of humic acid (HA) from surface water using ZnO nanoparticles and sun light using photo-Fenton-type reaction. Santra and Basumallick Banik and Basumallick (2017), Basumallick and Santra (2017) designed a fluorescence sensor for the detection of ppm level HA in surface water.…”

The present paper reports aggregation behaviour of humic acid (HA) in the presence of silver nanoparticles. Aggregation behaviour has been studied from dynamic light scattering (DLS) measurement, in the presence of silver nanoparticle. Silver nanoparticle has been prepared through chemical route and characterized by plasmon resonance spectroscopy. HA used in the study has been characterized by UV–Vis and fluorescence study; its charged state has been evaluated from the study of its interaction with a cationic dye ruthenium bipyridine. It has been found that HA forms small–medium- and large-sized aggregates in the presence of silver nanoparticle as obtained from DLS diameter. The result has been explained in terms of Langmuir–Hinshelwood adsorption model. It has been proposed that hydrogen bonding and hydrophobic interaction play an important role in the formation of aggregates of HA.
