Effect of poly ethylene glycol (PEG) as surfactant on cerium doped ZnS nanoparticles

Investigation of the Characteristics and Antibacterial Activity of Polymer-Modified Copper Oxide Nanoparticles

“…The estimated crystallite sizes are 24.84, 23.30, 22.86, 24.03, and 21.79 nm for pure CuO, CuO-PEG, CuO-PVP, CuO-PDA, and CuO-PVA, respectively. The crystallite size of polymer-modified CuO is smaller than pure CuO, which can be attributed to the Cu 2+ ions forming a complex with the polymer [ 27 , 28 , 29 , 30 ]. From the XRD spectra of polyethylene glycol (PEG) and polyvinylpyrrolidone (PVP)-modified CuO nanoparticles ( Figure 1 b,c), it can be observed that the characteristic peaks matched the diffraction peaks of pure CuO, showing that intact CuO crystal plane structures were retained in the surface-modified samples.…”

Optoelectronic Properties of Alumina–Tin Oxide Nanocomposites Deposited on 1D Carbon Backbone

“…The average crystallite size of 5.185 nm for SnO 2 was obtained from Debye-Scherrer equation. The small size of SnO 2 is because of addition of excess PEG as a precursor for 1D carbon backbone is also acting as a capping agent during preparation [25].…”

Influence of Biofield Treatment on Physical and Structural Characteristics of Barium Oxide and Zinc Sulfide

“…The absorption peaks found at 1398, 1425, and 1444/cm in control, T1, and T2 respectively, could be due to formation of BaCO 3 after CO 2 absorption by BaO sample from atmosphere [41]. Besides, IR spectra of ZnS powder is illustrated in Figure 8, in which absorption peaks observed at 592/ cm (control), 617/cm (T1) and 590/cm (T2) that were assigned to Zn-S stretching vibrations [42,43]. It indicates that absorption peaks were changed in treated sample as compared to control, which could be due to alteration in Zn-S bond length after biofield treatment.…”
