Nanoparticles or nanofillers are collective terms for modified layered silicates (organoclay), graphite nanoflakes, carbon nanotubes, and a number of materials dispersed in the polymer matrix, when the particles size is in order of nanometers (one thousands of micron), or tens of nanometers. A plastic filled with nanoparticles, typically in the range of 2-10% (w/w) is called a nanocomposite.

Additively, two control experiments were performed. The first experiment involved excluding either cadmium salt or selenium precursor from the reacting mixture. When no cadmium was added, the solution had a brownish colour but no precipitate formed. A white flake-like precipitate with fibre-like structure was observed when Se precursor was excluded from the reaction mixture. In the second control experiment, the pH value of Cd salt solution in 1) glycine and 2) water was raised until the hydrolysis of cadmium started (pH 10 and pH 7, correspondingly). In both cases a white precipitate formed. The precipitate formed as a result of the hydrolysis of Cd in water was powder-like, while the product formed in glycine had a flake-like appearance. TEM images of these precipitates are fibre-like for both samples. This confirms that such features previously seen in other samples were formed due to the hydrolysis of cadmium ions, which would result in the formation of Cd(OH)x. The formation of such nanoflakes was previously reported for the synthesis of cadmium hydroxide in an aqueous media by hydrothermal method [2].

Hosseini-Sarvaria (2011b) reported the synthesis of quinoline derivatives (60) by the condensation of 2-aminoaryl ketones (58) with methylene carbonyl compounds (59) catalyzed by nanoflake ZnO as a reusable heterogeneous catalyst under solvent-free conditions involving Friedlander heteroannulation (Scheme 9.14). The employed catalyst was synthesized from zinc acetate dihydrate and urea. It constitutes a simple, environmentally benign, and cost-effective method for the synthesis of quinolines. Tamaddon and Moradi (2013) reported the application of nano-ZnO as a reusable heterogeneous catalyst for the synthesis of Biginelli dihydropyrimidines... 

A green synthetic protocol under solvent-free conditions for the synthesis of phos-phono malonates (162) from alkenes (160) and phosphorous nucleophiles (161) using nanoflake ZnO at 50°C has been documented (Scheme 9.52) (Hosseini-Sarvari and Etmad 2008). The reaction is an example of one of the most powerful and important C-P bond-forming reactions, which is the phospha-Michael addition. The advantages of this method include mild reaction conditions, a simple set up, high yields, and so on. The formylation of amines (163) with formic add (70) under solvent-free...
