The aim of this study is to investigate in-depth the effect of Co2+ ions doping on ZnFe2O4 nanoparticles in term of morphology, magnetic and optical properties. Zn1-xCoxFe2O4 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5) powders were prepared by co-precipitation method. X-ray diffraction (XRD) and Energy Dispersive Spectroscopy (EDS) confirmed [...]

The objective of this paper is to analyze temporal and seasonal trends of air pollution in Bahrain between 2006 and 2012 by utilizing datasets from five air quality monitoring stations. The non-parametric and robust Theil-Sen approach is employed to study quantitatively temporal variations of particulate matter (PM10 and PM2.5), nitrogen [...]

Nanotechnology is often described as an emerging technology – one that not only holds promise for society but also is capable of revolutionizing our approaches to common problems. It is an emerging technological field with great potential to lead in breakthroughs that can be applied in real life. Novel nano-/biomaterials [...]

This chapter discusses the mechanism of photocatalysis processes using nanomaterials and their applications. It also focuses on the different types of nanomaterials used in photocatalysis in terms of their synthesis method, microstructure, and their optical and magnetic properties. A number of photocatalytic materials are synthesized by employing hydrothermal methods, such [...]

A novel low-cost broadband photodetector was fabricated based on nanostructures SnS thin film with cubic crystal structure. The SnS thin film was prepared by means of chemical bath deposition. The photodetector demonstrated a high performance for abroad range light detection from UV to near-infrared. The photoresponse characteristics were tested under [...]

Finite time convergence based on robust synergetic control (SC) theory and terminal attractor techniques is investigated. To this end a fast terminal synergetic control law (FTSC) is applied to drive a DC–DC Buck converter via simulation and through a dSpace based experimental setup to validate the approach. As robust as [...]

Zinc Sulfide (ZnS) quantum dots (QDs) embedded in sol-gel silica single-layer films were synthesized by dip-coating and thermal treatment. Nucleation and growth of these QDs occurred during annealing. The effect of annealing temperature on morphological, structural and optical properties of the films was considered in the range (200–500 °C). Scanning [...]

In this research work, structure, microstructure, optical and photocatalytic properties of undoped and Erbium doped nanostructured ZnO thin films prepared by sol-gel dip-coating are investigated. X-ray diffraction (XRD) analysis indicates that the deposited films crystallize within the hexagonal wurtzite-type structure with a preferential growth orientation along (002) plane. Morphological observations [...]

The objective of this study is to identify the most important air pollutants based on their individual contribution to Air Quality Index (AQI) and to determine the major air pollution sources in Bahrain. Data sets from seventeen air quality monitoring sites were evaluated using XLSTAT 2014 and Statistical Package for [...]

This paper presents the investigation of the influence of the ammoniating time of GaN nanowires (NWs) on the crystalline structure, surface morphology, and optical characteristics. Morphological analysis indicates the growth of good quality and high density of NWs with diameters around 50 nm and lengths up to tens of microns [...]
