Ti-doped ZnO nanorods (NRs) have been deposited onto Si substrates at 93 °C by using chemical bath deposition method. FESEM observations show high-quality NRs. FTIR spectra display main peak around 560 cm−1 associated with Zn–O bond in addition to minor peak detected around 500 cm−1 referred to Ti–O bond. XRD patterns reveal the [...]

Monitoring marine biodiversity is costly and practical solutions have to be implemented to identify species and their preferred habitats, particularly in this era of rapid global change. Citizen science has proven to be effective and with high potential for monitoring efforts, and has been extensively applied to biodiversity. We have [...]

A novel, flexible, and low-cost infrared (IR) SnS photodetector was fabricated onto a polyethylene terephthalate (PET) substrate by a simple approach based on chemical bath deposition. X-ray diffraction analysis confirmed an orthorhombic structure, scanning electron microscopy observations revealed flower-like morphology, and UV-vis spectroscopy indicated a direct energy gap of 1.42 [...]

This study investigated the characteristics of convective heat transfer and fluid flow for a heated plate surrounded by unheated plates aligned at angles to the flow direction inside a rectangular duct. The plates were arrayed in two main geometries: inline and staggered. Flow deflections within the array of aligned plates [...]

Nanoporous silicon (n-PSi) with diverse morphologies was prepared on silicon (Si) substrate via photo-electrochemical etching technique. The role of changing current density (15, 30 and 45 mA cm-2) on the structure, morphology and optical properties was determined. As-prepared samples were systematically characterized using XRD, FESEM, AFM and photoluminescence measurements. Furthermore, [...]

Several research studies have revealed the potential use of salt hydrates in thermal energy storage applications. These materials dissociate into anhydrous salts and release water vapor when subjected to heat source. The latter salt has the capability to store the energy that was supplied for dehydration upon heating. This thermal [...]

This article focuses on the asset price volatility at the stock exchange that result from the regime switching behaviour in the market. This study is devoted to the question about how the asset price volatility affects the US sovereign debt market. The efficient market hypothesis has been a base for [...]

Wind energy has become an attractive alternative to satisfy the ever-growing energy demands worldwide. One important factor that contributes to efficient energy harnessing from a wind farm is the selection of appropriate wind turbines for a specific site. This paper addresses this important issue through a goal programming based multi-criteria [...]

This article shall investigate the feasibility of utilizing wind energy for commercial buildings with special reference to the Kingdom of Bahrain. Bahrain World Trade Center which was built in 2008, is located in the city of Manama. The fifty-story complex contains identical twin towers that rise over 240 meters in [...]

The Kingdom of Bahrain falls geographically in one of the driest regions in the world. Conventional fresh surface water bodies, such as rivers and lakes, are nonexistent and for water consumption, Bahrain prominently relies on the desalination of sea water. This paper presents an ongoing project that is being pursued [...]
