The aim of the present study was to determine content capsaicin and dihydrocapsaicin in Capsicum samples collected from city markets Riyadh (Saudi Arabia), calculate their pungency Scoville heat units (SHU) evaluate average daily intake for population Riyadh. investigated consisted hot chillies, red green peppers, peppers yellow peppers. Extraction capsaicinoids done using ethanol as solvent, while high performance liquid chromatography (HPLC) used separation, identification quantitation...
This work reports the successful preparation of nanoporous iron oxide/carbon composites through in-situ growth Prussian blue (PB) nanoparticles on surface graphene oxide (GO) nanosheets. The applied thermal treatment allows conversion PB into (Fe2O3) nanoparticles. resulting composite exhibits higher specific capacitance at all scan rates than pure GO and Fe2O3 electrodes due to synergistic contribution electric double-layer from pseudocapacitance Fe2O3. Notably, even a high current density...
A solid phase extraction method is established for preconcentration of nickel, lead, cadmium, copper and cobalt using pipette tip extraction. The presented process was dependent on chelation analytes with 1,3,4-thiadiazole-2,5-dithiol, then allowing the solution to flow through an activated carbon cloth packed tip. adsorbed metal chelates surface were eluted by 5 mL 3 M HNO3. concentrations detected a flame atomic absorption spectrometer (FAAS). exhibit factor 120. limit detection values...
A supercapattery is a hybrid device that combination of battery and capacitor. Niobium sulfide (NbS), silver (Ag2S), niobium (NbAg2S) were synthesized by simple hydrothermal method. NbAg2S (50/50 wt% ratio) had specific capacity 654 C g-1, which was higher than the combined capacities NbS (440 g-1) Ag2S (232 g-1), as determined electrochemical investigation three-cell assembly. Activated carbon to develop asymmetric (NbAg2S//AC). maximum 142 g-1 delivered The (NbAg2S/AC) provided 43.06 W h...
Remediation of industrial water pollution is a trending subject to date for the researchers around globe, due its detrimental effects on human life as well aquatic life. Azo dyes are largest polluters in respect volume while anthraquinone second largest. Therefore, humongous considerations being enumerated removal and decolorization azo (AZ) dyestuff; however, (AQ) dyes, these efforts considerably minimal; although later one poses greater threat environmental contamination, because their...
Nowadays, for environmental remediation, photocatalytic process involving graphene-based semiconductors is considered a very promising oxidation water treatment. In the present study, nanocomposite (Cu/Ni/rGO) has been synthesized by Dypsis lutescens leaf extract. Characterization of sample was carried out UV-visible spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, Fourier transform infrared spectroscopy (FTIR), and diffraction (XRD). Different...
Due to increasing urbanization and population growth, municipal solid waste management (MSWM) is a significant environmental concern in developing countries. Inadequate systems lead pollution, health hazards, economic losses. While considering the challenges limitations, policymakers authorities need opt for such scenarios that are environmentally friendly resolve energy issues. Ten MSWM were developed evaluated using seven different criteria. Four multi-criteria decision-making (MCDM)...
Wastes must be managed properly to avoid negative impacts that may result. Open burning of waste causes air pollution which is particularly hazardous. Flies, mosquitoes and rats are major problems in poorly surroundings. Uncollected wastes often cause unsanitary conditions hinder the efforts keep streets open spaces a clean attractive condition. During final disposal methane generated, it much more effective than carbon dioxide as greenhouse gas, leading climate change. Therefore, this study...
