Modified carbon nanotube & poly (3-hexylthiophene) nanocomposites integrated in quasi solid-state dye synthesized solar cells

Karim M.R., King Saud University, SA

Poly (3-hexylthiophene) (P3HT) and modified (functionalized and silanized) multi wall carbon nanotube (MWNT) nanocomposites have been prepared through in-situ polymerization process in chloroform medium with FeCl3 oxidant at room temperature. The composites (P3HT-MWNT) are characterized [...]

Micro-particle Electrical Conduction through Human Blood

Abdalla S., Al-Ghamdi A.A., Marzouki F., King Abdulaziz University Jeddah, SA

The electric properties of human blood is vital. This is normal because this viable fluid have huge quantity of unexplored domains about its properties. For example, only few authors have examined the correlation between the [...]
