Synthesis and Optical Characterization of CuO Nanoparticles on Solar Borosilicate Glass

Abstract

In this communication we report on the optical property of CuO nanoparticles prepared by cost effective, simplistic and environment-friendly sol-gel technique on borosilicate glass by dip coating. The particle size was analyzed by Transmission Electron Microscope (TEM) which depicted particle size of CuO ~ 5 nm. To understand the optical behavior of nanosized CuO particles on borosilicate glass tube UV-visible spectrum has been taken. Effective mass model calculations determined the size of particles as 2.26 nm, which supports the TEM analysis. Samples were also analyzed by Fourier transform infrared spectrum (FT-IR) to understand the chemical bond in detail.

Simultaneous Adsorption of Ternary Antibiotics (Levofloxacin, Meropenem, and Tetracycline) by SunFlower Husk Coated with Copper Oxide Nanoparticles

“…Moreover, the band detected at 1641.4 cm -1 has similar vibration stretching patterns to the carbonyl group or carboxylic bonds (Dostert et al, 2016). This is most likely caused by the reactive carbon-containing plasma groups that are activated throughout the synthesis of CuO nanoparticles (Ramani et al, 2015). The FTIR spectra for CSFH after the adsorption procedure of three medicinal items are shown in Figure 2c.…”

Experimental Investigation On Nanoparticles Suspended Liquid (NSL) As The Heat Transfer Fluid (HTF) For Solar Evacuated Tube Collector

“…On the physicochemical profile, they have better stability when dispersed in a base fluid even without the addition of stabilisers. Paraffin oil, Ethylene Glycol (EG) or Propylene Glycol (PG) used as base fluids to improve thermal conductivity for TiO2 NSL [17][18][19][20][21]. Investigation shows that for CuO NSL preparation the sonication time greatly affects the heat transfer performance & influenced by the nanoparticles concentration.…”

“…Complete mixture is stirred for complete dispersion of nanoparticles. Stirring with heating takes place at 170 °C for 45 minutes [19,20]. At the end of this task, complete dispersion of powder takes location and NSL is prepared.…”

Nanoclay-based conductive and electromagnetic interference shielding properties of silver-decorated polyaniline and its nanocomposites

“…17 Larger permittivity readings at smaller frequencies may be attributed to electrode polarization and space charge polarization effects. 21,22 The decrease in dielectric constant values with increasing applied frequencies can be explained using the Maxwell-Wagner polarization model. 23,24 The variation in the dielectric constant at different frequencies can be explained by the hopping frequency of charge carriers, which tends to follow the applied frequency and results in higher dielectric constant values.…”
