XRD and FTIR studies for Ag/PMMA Nano composite thin films

Greener Synthesis, Characterization, and Antimicrobiological Effects of Helba Silver Nanoparticle-PMMA Nanocomposite

“…It shows that in all the peaks, the metallic pure silver had spherical structure. Refraction was provided by many peaks at about 2θ =35-70°while the first and second peaks were assigned to the lattice planes (1 1 1) and (2 0 0), respectively [21][22][23]. In addition to that, the polymer/AgNP composite patterns exhibited a two-phase (crystalline and amorphous) structure.…”

“…From the spectra of Figure 4(a), it can be seen that the band at (Figure 4(b)), the peaks at 550-650 cm -1 were from the Ag-C stretching vibration, which further proved the existence and reaction between Ag and long-chain alkyl of PMMA. In addition, shifts in C=O ester carbonyl group, C=C, CH 3 , and C-C for the AgNP/PMMA nanocomposite thin films were also seen, which indicated the modification of PMMA thin film structures by the AgNPs [23,[27][28][29].…”

Antimicrobial Activity of TiO2 NPs against Escherichia coli ATCC 25922 and Staphylococcus aureus ATCC 25923

“…A pathogenic E. coli can cause diarrheal disease, serious sequelae, urinary tract infection, meningitis, and septicemia [8]. Bacteria cells are surrounded by the plasma membrane, a lipid bilayer which contains opposing monolayers, or leaflets, of phospholipids with the hydrophilic head groups facing the extracellular and intracellular solutions, and the hydrophobic tails facing each other [9][10][11][12] characteristics of nanoparticles attributed to their structures, size (usually ranging from 1 to 100nm), higher surface-tovolume ratios (increased the located atoms at the grain boundaries) thus they exhibit significantly novel physical, chemical, and biological properties [13][14][15][16]. The possibility of NPs permeation inside the bacterial cell membrane due to their potential toxicity mechanism such as diffusion, endocytosis and channel implication so NPs have been used to be an antimicrobial agent against microbes such as bacteria [17][18][19][20][21][22][23].…”

Moreover NPs provided wide range of application in varied fields including solar energy conversion, catalysis, medicine, biotechnology, environmental electronics and optics [24][25][26][27][28]. Semiconductor materials such as TiO2 NPs (3.2 eV) are produced at a large scale for remediation and destruction of organic pollutants due to their unique physicochemical properties [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44].…”

Deposition of Colloidal Titanium and Copper Nanoparticles by Pulsed Laser Ablation on Si Solar Cell to Increase the Efficiency

“…The beat laser removal in fluid framed when an objective is inundated in a fluid. This strategy (as known as scattering technique) is investigated as a prospective top-down method for nanoparticles readiness of metals [5][6][7][8][9]. This procedure PLAL is another materials handling method that can offer lower cost and basic approach to perform.…”
