In this paper, the adsorption of Congo red dye from an aqueous solution using chitosan-coated pumice (CCP) has been studied. The abundant natural Irind mine (Republic Armenia) was successfully activated by acid activation method and modified with chitosan. adsorbent applied as a low-cost, environmentally-friendly for removal solution. samples were characterized Fourier-transform infrared spectr...

background and aims. this study was aimed at evaluating the effect of different prophylaxis methods on microleakage of microfilled composite restorations. materials and methods. in this in vitro study, class v cavities were prepared on buccal surfaces of 84 bovine teeth. the teeth were restored with tetric n-bond adhesive and heliomolar composite resin. subsequent to a thermocycling procedure a...

Pervious concrete is a developing construction material used for sustainable solutions which helps restore the groundwater level based on its draining ability. The existing research studies address strength and permeability of pervious-concrete materials only limited data available microstructural characteristics pervious concrete. In this study, characteristic analysis was carried out at micro...
