Fe3O4@ZnO nanocomposites (NCs) were synthesized to improve the stability of the wormlike micelle (WLM) network structure of viscoelastic surfactant (VES) fracturing fluid and were characterized by Fourier transform infrared spectrometry (FT-IR), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), X-ray diffraction (XRD) and vibrating sample magnetometry (VSM). Then, an NC-enhanced viscoelastic surfactant solution as a fracturing fluid (NC-VES) was prepared, and its properties, including settlement stability, interactions between NCs and WLMs, proppant-transporting performance and gel-breaking properties, were systematically studied. More importantly, the influences of the NC concentration, shear rate, temperature and pH level on the stability of NC-VES were systematically investigated. The experimental results show that the NC-VES with a suitable content of NCs (0.1 wt.%) shows superior stability at 95 °C or at a high shear rate. Meanwhile, the NC-VES has an acceptable wide pH stability range of 6–9. In addition, the NC-VES possesses good sand-carrying performance and gel-breaking properties, while the NCs can be easily separated and recycled by applying a magnetic field. The temperature-resistant, stable and environmentally friendly fracturing fluid opens an opportunity for the future hydraulic fracturing of unconventional reservoirs.

A new metal−organic framework (MOF), [Zn 4 (μ 4 -O)(μ 6 -L) 2 (H 2 O) 2 ] n • nDMF (ZSTU-10), was assembled from zinc(II) nitrate and N,N′,N″-bis(4carboxylate)trimesicamide linkers and fully characterized. Its crystal structure discloses an intricate two-fold 3D+3D interpenetrated MOF driven by the [Zn 4 (μ 4 -O)]-based tetragonal secondary building units and the C3-symmetric tris-amide-tricarboxylate linkers (μ 6 -L 3− ). Topological analysis of ZSTU-10 reveals two interpenetrated 3,6connected nets with an rtl (rutile) topology. Z-Scan analysis at 532 nm was conducted to study a nonlinear optical (NLO) behavior of ZSTU-10. The nonlinear responses of ZSTU-10 were explored under various laser intensities, revealing notable third-order NLO properties in the visible region. A large two-photon absorption at lower incident intensities highlights the fact that ZSTU-10 can be applied in optical limiting devices as well as optical modulators. Moreover, a nonlinear refractive index (n 2 ) is indicative of a self-defocusing behavior. This work thus expands a family of novel MOF materials with remarkable optical properties.

“…Consequently, different parameters (including particle size, surface passivation, and nature of the employed organic moieties along with the electronic band structure) should be considered to take the NLO responses of these carbon-based nanomaterials into account [38]. Porosity is one of the most important reasons for the nonlinear optical responses of CNO [36]. Moreover, nonlinear scattering could be another factor for recorded nonlinearity responses, especially at higher intensities [38].…”

The nitrogen-doped carbon nano-onions (NCNOs) were prepared by annealing the ultra-dispersed aminated-nanodiamond solution under He gas at 1150°C followed by calcination at 400°C. The nanostructures of CoWO4, MnO2, CoWO4-MnO2, and CoWO4-MnO2-NCNO were synthesized through the simple precipitation method under ultrasonication followed by calcination at 450°C. The morphology, structure, and optoelectronic properties of the samples were examined by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and Z-scan method. The homogeneous distribution of the tiny aggregated plate-like and spongy particles throughout the nanocomposite created a highly porous nanostructure with a large surface area. The nonlinear absorption (NLA) coefficient and nonlinear refractive (NLR) index were of the order of 10-3(cm/W) and 10-8(cm2/W), respectively. In different incident intensity of laser, all synthesized samples show TPA effect implying the positive sign of NLA coefficient. MnO2 and NCNO structure have positive NLR index indicating the self-focusing optical nonlinearity. The self-defocusing effect and the negative sign of nonlinearity in the CoWO4 nanoparticles, MnO2-CoWO4, and MnO2-NCNO-CoWO4 nanocomposites are vivid. The porous structure of CoWO4 nanoparticles and trapping the light into CoWO4 nanoparticles are the main reasons for nonlinearity of this nanoparticles. Porosity is also one of the most important reasons for the nonlinear optical responses of NCNO structure. The NLR index and NLA coefficient of MnO2 decreased by increasing the incident intensity. Moreover, an increase in the incident intensity improved the nonlinear responses in the rest of samples. The present nonlinear optical results of the synthesized samples can be applied in optical devices.
