TLDR
In this paper, it has been shown that no metallic palladium is present after the nucleation procedure of nonconducting substrates with stannous chloride and palladium chloride solutions, and the results indicate that a tin-palladium complex, containing one palladium atom per two tin atoms is formed and that this initiates the nickel-phosphorus deposition from a suitable electroless plating solution.Abstract:
It has been generally accepted that metallic palladium nuclei are formed by the nucleation procedure of nonconducting substrates with stannous chloride and palladium chloride solutions. However, results of experiments on glass using radioactive tracers and ellipsometry have shown that no metallic palladium is present after the nucleation procedure. The results indicate that presumably a tin‐palladium complex, containing one palladium atom per two tin atoms is formed and that this initiates the nickel‐phosphorus deposition from a suitable electroless plating solution.read more

Thin-film transistors with active layers of zinc oxide (ZnO) fabricated by low-temperature chemical bath method
TL;DR: In this article, thin-film transistors (TFTs) with active channel layers of zinc oxide (ZnO) using a low-temperature chemical bath deposition have been studied, where the ZnO films were fabricated on the defined-areas of bottom-gate type TFTs plate by immersing in a chemical bath containing zinc nitrate (zn(NO 3 ) 2.6H 2 O) and dimethylamineborane (DMAB) at 60 °C.

Electroless plating of palladium and copper on polypyrrole films
TL;DR: In this paper, the electroless plating of copper on polyaniline (PANI) films of different intrinsic oxidation states, viz, the emeraldine base (EB), the nigraniline and the leucoemeraldine (LM) states, in the complete absence of surface sensitization by SnCl2 was explored.
