This study was performed to verify the possibility of MTA and calcium sulfate as a pulp capping agent through comparing the dental pulp response in dogs after capping with MTA, calcium sulfate, and calcium hydroxide. 24 teeth of 2 dogs, 8 month old, were used in this study. Under general anesthesia, cervical cavities were prepared and pulp was exposed with sterilized #2 round bur in a high spee...

double layer zno/sno2 thin film resistive gas sensors were fabricated by successive pvd of those oxides onto porcelain substrates. the metallic contacts were provided by electron beam evaporation of platinum onto substrates prior to deposition of the gas sensitive layers. deposits were thermally annealed at different temperatures. it was shown that the activation energy of electrical conduction...

In article 1600229, Shilong Wang, Rongrong Zhu, Yechang Qian, and co-workers investigate the anti-metastatic and anti-angiogenic effects of SiO2@LDH (LDH: layered double hydroxide) loaded with etoposide (VP16). SiO2@LDH has very suitable qualities as drug delivery agent and enhances the anti-metastatic action of VP16 both in vitro and in vivo. Enhanced anti-angiogenic efficacy is also proven wh...

in this research, tribological characteristics of ni-p electroless coating and double-layered ni-p/ni-b electroless coating were studied. for this purpose, ni-p electroless coating with 25 μm thickness was initially applied to the surface of steel ck45 samples; then, a double-layered ni-p/ni-b electroless coating, including inner layer of ni-p with 15 μm thickness and outer layer of ni-b with 1...

Objectives: The aim of the study was to evaluate the effect of calcium hydroxide on the adhesion of a resin system to dentin by scanning electron microscopy (SEM). Methods: Cavities were prepared on the mesial and distal sides of 10 extracted lower human molars. The mesial cavities were coated with Prime & Bond 2.1 (Caulk, Dentsply) after total etching, and were restored with TPH composite resi...
