In this research, using phenolic resin as the precursor of carbon and various amounts of ethylene glycol as a pore former, porous samples of hard carbon were synthesized. Samples were characterized by x-ray diffraction (XRD) and N2 adsorption-desorption methods. Broad diffraction peaks represent the amorphous structure of samples. Moreover, the gas adsorption-desorption curves showed that the a...
Recently, polymeric nanocomposites have been used as real-time detectors and dosimeters of gamma radiation. In this experimental work, multi-wall carbon nanotubes (MWCNT) were dispersed in polystyrene (PS) martix with a weight percentage of 0.05 wt%. SEM images confirmed the appropriate and uniform distribution of carbon nanotubes in the polymer matrix. The dark current and photocurrent of the ...
Activated carbon from pine cone (PCAC) was used as a precursor to prepare Fe3O4/magnetic activated carbon (MPCAC). Here, the removal of linear alkylbenzene sulfonate (LAS) was studied using catalytic ozonation process (COP) in exposure to MPCAC. Subsequently, it was compared with PCAC. Moreover, the effects of solution's initial pH, catalyst dosage, and the time of ozonati...
