Abstract. This work deals with the synthesis of nanoparticles iron-potassium diphosphate, KFeP2O7, implanted on activated carbon produced from corncob debris. The chemical composition and structure carbon/potassium-iron diphosphate (AC/KFP) composite was analyzed by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) Transmission (TEM). Complementary tests were conducted to determine su...

The relationships between the transmission coefficient and the cure depth were evaluated on eight commercially available light-activated resin composites. The determination of transmission coefficient was carried out by the use of a radiometer for various shades of the resin composites. The transmission coefficient, ranging from 0.042 to 0.263, wasdependent upon the shade of the resin. There wa...

Nanopowders of Al2O3, TiO2 and MgO were fabricated by high energy ball milling. The simutaneous synthesis and sintering of nanostuctured MgAl2O4-Mg3Al4Ti3O25 composite was investigated by the pulsed current activated sintering process. The advantage of this process is that it allows very quick densification to near theoretical density and inhibition of grain growth. A highly dense nanostructure...

Light activated polymers (LAPs) have attracted increasing attention since these materials change their shape and/or behavior in response to light exposure, which serves as an instant, remote and precisely controllable stimulus that enables non-contact control of the material shape and behavior through simple variation in light intensity, wavelength and spatially controlled exposure. These featu...

An activated carbon/epoxy composite was synthesized in which waste mango leaves biomass used as the carbon source. To create a sufficient amount of porosity biomass, simple process carbonization followed by its activation used. The morphology and material were studied SEM, TEM, BET analysis, confirmed presence macro- mesopores material. with 3 mm thickness gave highest reflection loss (RL) ? 39...

In this study, titanium dioxide (TiO2) and – activated carbon composite (TiO2–AC) were prepared by sol-gel method for photoelectrochemical (PEC) applications. Characterization of the materials was performed scanning electron microscope, energy dispersive X-ray analysis, Fourier transform infrared spectroscopy, diffraction, diffuse reflectance spectroscopy. The results show that TiO2 successfull...
