“…The results presented in figure 8 yield a nonlinear refractive index of n I 2 = (−10.6 ± 1.0) × 10 −7 cm 2 W −1 and a nonlinear absorption of β = (−1.78 ± 0.02) × 10 −2 cm W −1 , which are consistent with the values obtained in our previous study [21], considering a 3 mM difference in the sample concentration between the samples in the two works.…”

“…The sample under investigation is a cuvette containing AgNPs dispersed in water with a 15 mM concentration. The AgNPs are synthesized based on the complexing agent method, which is completely explained in our work previously released [21]. The experimental findings indicate that the proposed tunable liquid lens yields highly consistent results with those obtained by the conventional z-scan experiment.…”

“…The schematic of a required experimental setup is presented in figure 6. The AgNPs are synthesized based on using the complexing agent method and the synthesis was carried out under controlled pH conditions of 10.82 to produce Ag nanoparticles with a mean size of approximately 8.64 ± 0.70 nm as determined from a transmission electron microscopy image captured using a commercial tool (Zeiss, EM900) at room temperature and relative humidity of 19% [21]. The characterized AgNPs are eventually suspended in distilled water with a molar concentration of 15 mM to provide the necessary sample for z-scan investigation.…”

A water-injected liquid lens is fabricated to tune its focal length using the change of water salinity. It is found that when the salinity of water is changed from zero to 34.25%, the focal length can be changed by about 12.6 mm from 73.7 mm to 86.3 mm. A focal length resolution of approximately 0.75×10-2 mm and a high temporal stability over a long period have been achieved for the lens foci. This lens is then used to modify the z-scan technique where the lens and the sample are both remained fixed without displacement. The performance of the fabricated lens is evaluated by nonlinear refractive index measurement of a sample containing 10.82-pH-syntesized Silver nanoparticles (AgNPs) suspended in water with 15 mM of concentration. For verification of the results, nonlinear refraction index of (-10.6±1.0)×10-7 cm2/W is firstly measured for the sample using a classical z-scan benefiting from conventional focal-fixed lens. Interestingly, we found out that when the fabricated lens if replaced in the modified z-scan, the nonlinear refraction index of about (-8.1±0.2)×10-7 cm2/W can be measured, indicating a similarity in the order and small difference in the coefficient compared to the classical z-scan. This outcome highlights the potential capability and simplicity of the fabricated lens in the modification of classical z-scan technique.

Excessive utilization of nanoparticles renders it necessary to produce safer and more secure nanoparticles while preserving their efficacy. In this study, Psidium guajava L. pulp extract-mediated silver nanoparticles (AgNPs) were synthesized, characterized, and further evaluated regarding their antioxidant potential. The green synthesized silver nanoparticles (G-AgNPs) showed a higher level of radical scavenging activity (RSA) (25.85%), hydrogen peroxide scavenging activity (34.34%), and ferric reducing power (0.28). The comparison of the control group (G1) with the various treatment groups (G2-G6) revealed that the levels of catalase (CAT), superoxide dismutase (SOD), and glutathione-S-transferase (GST) were significantly different (P < 0.05). The levels of blood urea, uric acid, blood urea nitrogen (BUN), serum glutamic pyruvic transaminase (SGTP), serum creatinine, serum glutamic-oxaloacetic transaminase (SGOT), alkaline phosphatase, total bilirubin, and serum electrolytes were also evaluated. The results of clinical biochemistry also strengthened our hypothesis that G-AgNPs are less toxic than C-AgNPs. Finally, the histopathology of liver, kidney, and intestinal tissues indicated that green-synthesized AgNPs are relatively safer.

“…The structure and morphology at the nanoscale are responsible for fascinating phenomena like the Localized Surface Plasmon Resonance (LSPR), quantum confinement in discrete states and the sharpselective optical response exhibited by metallic nanoparticles [6]. Nonlinear optical properties can be tailored by nanoparticle size [7], entropy [8], mechanical stress [9], plasmonics [10], morphology [11], distribution [12] or structure [13]. Permutation of processes in nonlinear optical systems dependent on LSPR can be tailored to derive in a dramatic increase in propagation modes with potential applications for developing all-optical switching devices [14].…”

In this work were numerically analyzed the third-order nonlinear optical effects exhibited by combinations of uncoupled monometallic silver, gold and platinum nanoparticles. The nanosystems were considered to be homogeneous and surrounded by a dielectric matrix. The design of the nanostructures was evaluated as a collective behavior resulting from the specific order of the set in trilayer tandem form. The characteristic Localized Surface Plasmon Resonance phenomena in the yellow, green and ultraviolet absorption bands for the Ag, Au and Pt; respectively, were considered. Different permutations of the three kind of monometallic elements selected in sequence were studied by using the wave equation and the finite difference method. Immediate indications useful for exploring nonlinear nanodevices and for building up nanostructured platforms based on nanoscale functions can be anticipated from this work.
