the fabrication of a non-doped red organic light-emitting device (oled) has been developed using naturally occurring curcumin as an emissive layer of oled. in this research, the electroluminescent spectrum (el) of curcumin as a donor-acceptor-donor (d-a-d) chromophore was obtained at wavelength of 612 nm. also, the maximum external quantum efficiencies (eqe) for this device was measured and fou...

The abundant presence of fluoride (F-) in surface water bodies is an environmental concern because its effects on human health; medical reports confirmed that intake above 1.5 mg/L leads to many health complications, including but not limited weak bones and enamel fluorosis. Thus, the World Health Organisation (WHO) defines 1.20 as maximum permissible F- concentration drinking water. electrocoa...

Background: Natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (DBPs) and membrane fouling during water filtration. In this study, the performance of the peroxi-electrocoagulation process (PEP) was investigated for the removal of humic acids (HAs) from aqueous solutions. Methods: PEP was carried out for the remov...

An optoelectronic device model for organic photodetector based on bilayer structure has been presented. Drift-diffusion and optical-generation from Synopsys tool have incorporated its optoelectronics behavior discussed. The shows an outstanding rectifying under dark condition due to the different work function of electrodes. Photocurrent density 6.64 mA/cm2 is found illumination 3 W/cm2. To ana...

Vertical heterojunction NiO/β n-Ga2O/n+ Ga2O3 rectifiers employing NiO layer extension beyond the rectifying contact for edge termination exhibit breakdown voltages (VB) up to 4.7 kV with a power figure-of-merits, VB2/RON of 2 GW·cm−2, where RON is on-state resistance (11.3 mΩ cm2). Conventional fabricated on same wafers without showed VB values 840 V and figure-of-merit 0.11 GW cm−2. Optimizat...

Oxygen evolution reaction (OER) is one of the most important anodic reactions in electrochemical conversion devices. Although a lot OER electrocatalysts have been developed, actual active sites during not fully understood. Herein, we report that distorted FeOOH/Ni hydroxide on Ni foam (NF) (d-FeOOH/Ni hydroxide-NF) shows better performance (1.50 V at 100 mA/cm2 and long-term stability for 32 h ...

Pristine TiO2 and Sr-doped (1%, 2.5% 5%) nanoparticles were synthesized at low temperatures via an eco-friendly hydrothermal route for water-splitting applications. XRD, EDAX Raman analysis performed to analyze the crystallinity, purity structure of as-synthesized materials. TEM, SEM, BET UV-DRS studies carried out elucidate size, morphology, surface area optoelectronic properties nanoparticles...

in the present study, the treatment of tannery wastewater was performed by electrocoagulationmethod (ec) using aluminium and steel electrodes. response surface methodology (rsm) with three factors; current density (i), electrolysis time (t) and ph, with each factor at five levels, was used to optimize the factors for higher chemical oxygen demand (cod) and total suspended solids (tss) removal. ...
