Production of activated carbon derived from agricultural by-products via microwave-induced chemical activation: a review

Environmentally friendly natural materials for triboelectric nanogenerators: a review

“…The porous structure of hair increases the charge of its internal structure, promoting the generation and accumulation of frictional charge and improving the performance of the resulting TENG. 154,155 Natural rubber (NR) with varying human hair (ACH) content was used as a tribopositive layer. PTFE and ITO were used as the tribonegative layer and the electrode, respectively.…”

Synthesis of Activated Carbon Composited With Egyptian Black Sand for Enhanced Adsorption Performance toward Methylene Blue Dye

“…The use of microwave technology to create AC from industrial agro-waste has been studied, and the results are encouraging [27]. They demonstrate that the process is economically viable because it is quick, high yield, selective heating, and can enhance the physical properties of materials such as high surface area, while also being environmentally friendly [28]. The electromagnetic waves which having frequencies between 300 MHz and 300 GHz are known as microwaves (wavelength between 1m and 1 mm) [29].…”

Enhancement of Uranium Recycling from Tailings Caused by the Microwave Irradiation-Induced Composite Oxidation of the Fe–Mn Binary System

“…The microwave (MW) irradiation technique has been widely applied in intensifying the chemical activities of materials. 51 − 53 MW can change the mineral microstructures and accelerate the dispersion of chemical reagents in the pores and fissures by intensely activating the vibrations of polar molecules in a very short time. 54 MW irradiation has achieved remarkable results for the fabrication and synthesis of different functionalized materials.…”

“…Some appropriate pretreatments and enhancements should be explored to avoid the dependence on higher acid concentrations. The microwave (MW) irradiation technique has been widely applied in intensifying the chemical activities of materials. − MW can change the mineral microstructures and accelerate the dispersion of chemical reagents in the pores and fissures by intensely activating the vibrations of polar molecules in a very short time . MW irradiation has achieved remarkable results for the fabrication and synthesis of different functionalized materials. , However, the comprehensive employment of MW in mining engineering has been rarely studied, especially for the hydrometallurgical engineering of refractory mineral ores.…”
