In this chapter, we review the application of zinc oxide (ZnO) in ultraviolet (UV) sensing and emphasise on the two-dimensional (2D) ZnO structures. The synthesis of 2D ZnO structures, the morphologies, and the photoluminescence emission will be reviewed and highlighted. The performance of the UV sensors based on 2D ZnO structures is explored. The lack in the study of the 2D ZnO UV sensors might be due to the difficulties of controlling the growth of the 2D ZnO compared to the one-dimensional (1D) ZnO structures.

“…), concerns were raised about the fate of these materials in their local environment. Zinc oxide nanoparticles, for example, have been extensively used in electronics, cosmetics (e.g., sunscreens, tooth paste, deodorants) and many other industries, Moezzi et al, 2012, Kurlanda-Witek et al, 2014. Zinc oxide, like Silver oxide, has antimicrobial effects which favor its use in cosmetic industries.…”

In this work the problem related to the transport of nanoparticles in anisotropic porous media is investigated numerically using the multipoint flux approximation. Anisotropy of porous media properties are an essential feature that exist almost everywhere in subsurface formations. In anisotropic media, the flux and the pressure gradient vectors are no longer collinear and therefore interesting patterns emerge. The transport of nanoparticles in subsurface formations is affected by several complex processes including surface charges, heterogeneity of nanoparticles and soil grain collectors, interfacial dynamics of double-layer and many others. We use the framework of the theory of filtration in this investigation. Processes like particles deposition, entrapment, as well as detachment are accounted for. From the numerical methods point of view, traditional twopoint flux finite difference approximation cannot handle anisotropy of media properties. Therefore, in this work we use the multipoint flux approximation (MPFA). In this technique, the flux components are affected by more neighboring points as opposed to the mere two points that are usually used in traditional finite volume methods. We also use the experimenting pressure field approach which automatically constructs the global system of equations by solving multitude of local problems. This approach facilitates to a large extent the construction of the global system. A set of numerical examples is considered involving two-dimensional rectangular domain. A source of nanoparticles is inserted in the middle of the anisotropic layer. We investigate the effects of both anisotropy angle and anisotropy ratio on the transport of nanoparticles in saturated porous media. It is found that the concentration plume and porosity contours follow closely the principal direction of anisotropy of permeability of the central domain.

“…In these materials, the presence of magnetic ions such as 3d (TM) and/or 4f (RE) ions leads to an exchange interaction between itinerary sp band electrons or holes and the d-electron spins localized at the magnetic ions, leads to versatile magnetic field-induced functionalities (Furdyna 1988). Recently, DMSs have fascinated researchers because of their potential applications in spin-based multifunctional electronic devices including spin field-effect transistors, optoelectronics, field emission devices, gas sensors, ultraviolet absorbers, quantum computer, and nonvolatile memory devices (Moezzi et al 2012;Chu et al 2009;Zhang et al 2009;Liu et al 2009;Neal et al 2006;Huang et al 2009). …”

Drastic improvement in magnetization of CdO nanoparticles by Fe doping

Hydrothermal route was used in the preparation of Fe-doped CdO nanoparticles with 3, 5, 7 and 10 wt% and their structural and magnetic properties were investigated. Structural characterization using powder X-ray diffraction confirmed the single phase cubic symmetry of these nanoparticles. Particle size decreased monotonically with increasing the dopant ion concentration. The microstructure of the synthesized samples was studied by a high-resolution transmission electron microscopy (HRTEM) which confirmed the nanocrystalline nature of the samples. A vibrating sample magnetometer provided the hysteresis curves of all samples. Pure CdO reveals ferromagnetic behavior while antiferromagnetization is observed for all Fe-doped samples. Large coercivity as well as large area for the sample x = 0.05 is achieved.
