But a challenge for its nanostructures is the limited solubility in non-toxic solvents, including water, which limits their processability in coating techniques. We overcame this challenge by synthesizing its copolymer with diphenylamine-4-sulfonate and its nanocomposite with titanium dioxide nanoparticles (TiO₂NPs). So through a solid-state and template-free technique and using sodium diphenylamine-4-sulfonate, aniline hydrochloride salt, TiO₂NPs, and FeCl₃∙6 H₂O as an oxidant, poly(N-(sulfophenyl)aniline) nanoflowers (<strong>PSANFLs</strong>), poly [(aniline-<em>co-N</em>-(4-sulfophenyl) aniline] nanofibers (<strong>PAPSANFs</strong>), poly(N-(sulfophenyl)aniline) nanofibers/titanium dioxide nanoparticles (<strong>PSANFs/TiO</strong>_{<strong>2</strong>}<strong>NPs</strong>), and poly (aniline-<em>co-N</em>-(4-sulfophenyl)aniline nanofibers/titanium dioxide nanoparticles (<strong>PAPSANFs/TiO</strong>_{<strong>2</strong>}<strong>NPs</strong>) were synthesized. Characterization of the synthesized samples was carried out through field emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectra, ultraviolet-visible spectra (UV-Vis), cyclic voltammetry (CV), and elemental analysis (CHNS). The FE-SEM images clearly illustrate that the synthesized samples are of nanoscale dimensions. The band gap values of 2.23 eV for <strong>PSANFs/TiO</strong>_{<strong>2</strong>}<strong>NPs</strong> and 1.96 eV for <strong>PAPSANFs/TiO</strong>_{<strong>2</strong>}<strong>NPs</strong> nanocomposites were determined through electrochemical calculations based on cyclic voltammetry curves, showcasing the complementary properties of n and p semiconductors.

This study delves into complex brain functional connectivity using biophysical nonlinear dynamics approaches. We aim to uncover hidden information in high-dimensional and nonlinear neural signals, with the hope of providing a useful tool for analyzing information transitions in functionally complex networks. By utilizing phase portraits and fuzzy recurrence plots, we investigated the latent information in the functional connectivity of complex brain networks. Our numerical experiments, which include synthetic linear dynamics neural time series and a biophysically realistic neural mass model, showed that phase portraits and fuzzy recurrence plots are highly sensitive to changes in neural dynamics and can also be used to predict functional connectivity based on structural connectivity. Furthermore, the results showed that phase trajectories of neuronal activity encode low-dimensional dynamics, and the geometric properties of the limit-cycle attractor formed by the phase portraits can be used to explain the neurodynamics. Additionally, our results showed that the phase portrait and fuzzy recurrence plots can be used as functional connectivity descriptors, and both metrics were able to capture and explain nonlinear dynamics behavior during specific cognitive tasks.
