Ultrasonic pretreatment of cowpea bean pod biomass with addition tripotassium phosphate (K3PO4) was used to induce the production bio-oil enriched in phenolic compounds. An ultrasound bath operating at 40 kHz, 154 W power, and constant biomass:K3PO4 ratio 5:1 (m/m) for pretreatments different durations: 0.5, 1.5, 3, 6, 8, 12 h. After pretreatment, pyrolyzed a fixed bed reactor 600 °C, under flo...

Sage (Salvia officinalis L.) is a popular herb which is native to the Mediterranean region and cultivated worldwide. Sage is an important source of antioxidants used as preservatives and has wider implications for the dietary intake of natural antioxidants.1,2 This antioxidant effect has been attributed to the main phenolic components, caffeic acid dimer – rosmarinic acid1 and flavonoids, being...

A ternary ZnO/Ag/CdO nanocomposite was synthesized using thermal decomposition method. The resulting nanocomposite was characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, UV-Vis spectroscopy, and X-ray photoelectron spectroscopy. The ZnO/Ag/CdO nanocomposite exhibited enhanced photocatalytic activity under visible light irradiation ...

A novel lamellar-structured Co/Co(OH)2 nanocomposite was synthesized with a room-temperature solution-phase reduction method. A possible reaction mechanism and shape evolutionary process for the Co/Co(OH)2 nanocomposite were supposed. The Co/Co(OH)2 nanocomposite shows a ferromagnetic behavior. Congo red (CR) was used to evaluate the Co/Co(OH)2 nanocomposite wastewater treatment capability. It ...

Cleaning contaminated water under light with a novel type of heterogeneous photocatalysts is regarded as critical method for wastewater resolution. Thus, unique mesoporous Ru-ZnO@g-C3N4 nanocomposite an increased surface area was synthesized through the ultrasonic technique in presence methanol. The X-ray diffraction pattern efficiently validated crystal structure Ru-ZnO hybrid and allowed it t...

Chitosan/multiwalled carbon nanotube nanocomposite has been successfully synthesized by the chemical method. The prepared nanocomposite was characterized using XRD, FTIR and HRTEM. The XRD pattern of the nanocomposite shows the presence of planes corresponding to both chitosan and MWCNT and the absence of impurity phases. The semi-crystalline nature of chitosan is also evident from the obtained...

We develop a facile, effective and filter free infiltration method to fabricate high performance, freestanding and superthin epoxy nanocomposite films with directly synthesized Sing-Walled Carbon Nanotubes (SWNTs) film as reinforcement skeleton. It is found that the thicknesses of the nanocomposite films can be easily controlled in the range of 0.5-3 μm by dripping target amount of acetone dilu...

Abstract Kaolinite is a widely available and inexpensive substance that has been successfully employed to decontaminate different hazardous contaminants from wastewater by adsorption. In this study, halloysite-like nanotubes (HNTs) were prepared via intercalation followed ultrasonic rolling of the kaolinite layers. Then, maghemite nanoparticles co-precipitated within HNTs matrix produce maghemi...
