“…By the Z-scan method, the nonlinear optical properties of the titanium nitride with different synthesis methods were performed. The Z-scan technique has the advantages of simplicity and high sensitivity; therefore it is an increasingly popular method to measure optical nonlinearities of materials [47]. Using the Z-scan setup, two important nonlinear optics parameters can be determined, both size and sign [46].…”

In this paper, titanium nitride nanoparticles were prepared in three methods, In the first method, titanium nitride nanoparticles were prepared by the Ball-mill method; in the second and third methods, the nanoparticles were synthesized by the sol-gel, and the co-precipitation methods. The samples were characterized by X-ray diffraction (XRD), UV-Vis spectroscopy, and scanning electron microscopy (SEM), for the study of structural, linear optical properties, and surface morphology study, respectively. The Z-scan technique was utilized to study the TiN nanoparticles nonlinearity. A change in nonlinear optical behavior with an increase in input pump power and concentration of the TiN nanoparticles was observed. Results showed that the TiN nanoparticles give new potentials in nonlinear optical applications. The nonlinear optical behavior of the TiN nanoparticles shifts from inverse saturation absorption to saturation absorption with increase of intensity.

“…[5][6][7] Contrastingly, the insoluble nature and lack of processability are the demerits of PANI and PPy. [8] The synthesis of polymer nanocomposites and copolymers can be utilized to resolve these paucities. [9,10] Thus, the ideology behind the synthesis of copolymer nanocomposites is that they possess excellent properties by removing discrepancy of properties of individual polymers.…”

A series of copolymer nanocomposites based on poly(aniline-co-pyrrole) (PANI-co-PPy) with different contents of copper alumina (Cu-Al 2 O 3 ) nanoparticles were synthesized by benign in situ chemical oxidation polymerization. The structural, thermal transition, and morphological interpretations were carried out by Fourier-transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), differential scanning calorimetry (DSC), and high-resolution transmission electron microscope (HR-TEM). The electrical properties such as alternating current (AC) conductivity and dielectric measurements were performed at room temperature to verify their application in developing new electronic devices. The presence of nanoparticles in the copolymer and the synergistic interaction in the copolymer matrix was confirmed by FTIR and XRD. HR-TEM indicates the nanosized uniform dispersion of nanofiller in the copolymer matrix. DSC revealed a reduction in the flexibility of polymer with an increase in glass transition temperature of copolymer composites. AC conductivity measurement manifested an increased hopping of charge carriers in nanocomposites when compared with pristine PANI-co-PPy. Dielectric properties were maximum for copolymer with 5 wt% Cu-Al 2 O 3 . Excellent gas sensing traits were observed for copolymer nanocomposites due to the electron transfers existing between PANI-co-PPy and ammonia gas. The maximum gassensing properties and electrical conductivity were observed for 5 wt% copolymer composites. The magnificent material properties make PANI-co-PPy/Cu-Al 2 O 3 nanocomposites, a promising contender for developing nano-electronic devices.
