This study investigated the effectiveness of polymerization of various curing regimes on five nanocomposite restorative materials—Z350, Grandio, Clearfil Majesty Esthetic, Ice and Tetric EvoCeram—by utilizing microhardness measurements. Five (n=5) disc-shaped specimens of each material were subjected to one of three curing regimes: curing with a halogen(More)
The electrochemical behaviour of beta titanium alloys, namely Ti-15Mo (TiMo) and Ti-29Nb-13Ta-4.6Zr (TNTZ), were studied under physiological conditions using open circuit potential (OCP), potentiodynamic polarization and electrochemical impedance spectroscopic (EIS) measurements. The OCP data for TNTZ alloy indicated a noble behaviour compared to TiMo(More)
Hybrid solar cells employing conjugated polymers have revolutionized the photovoltaic industry by offering the prospect for large-scale energy conversion applications through cost-effective fabrication techniques. In this regard, we have demonstrated an experimental approach to fabricate polypyrrole/ZnCoO nanorod hybrid systems, using hydrothermal and(More)
The combination of external potential dynamics and Brownian dynamics is introduced to study the kinetics of orientational ordering in block copolymer/superparamagnetic nanoparticle composites where the particles are smaller than the domain spacing and preferentially segregate into one block of the copolymer. This simulation method accounts for both excluded(More)
