Why Titanates and Zirconates May Be Better Adhesion

The reason why titanates and zirconates may be better adhesion promoters than silanes lies in the intrinsic multifunctional chemistry of organometallic titanium and zirconium as compared to silicone at the nano-interface where dissimilar materials meet (Figure 1). If you look at the periodic table according to atomic nuer, there seems to be little in common between Si, Ti and Zr (Figure 2a).

Covalently Bridging Gaps in Single-Walled Carbon …

Molecular electronics is often limited by the poorly defined nature of the contact between the molecules and the metal surface. We describe a method to wire molecules into gaps in single-walled carbon nanotubes (SWNTs). Precise oxidative cutting of a SWNT produces carboxylic acid–terminated electrodes separated by gaps of ≤10 nanometers.
