ETEM is thus used as a nanolaboratory with multi-probe measurements. Design of novel reactions and nanosynthesis are possible. The structure and chemistry of dynamic catalysts are revealed by atomic imaging, ED, and chemical analysis (via PEELS/GIF), while the sample is immersed in controlled gas atmospheres at the operating temperature. The analysis of oxidation state in intermediate phases of the reaction and, in principle, EXELFS studies are possible. In many applications, the size and subsurface location of particles require the use of the dynamic STEM system (integrated with ETEM), with complementary methods for chemical and crystallographic analyses. 

Growth of anisofiopic silicon and boron carbide nanoparticles from powdered reagents was performed using a process of exothermic nanosynthesis [6,7] (Fig. 3.8).

As was mentioned earlier, CHQ nanotube arrays can be utilized in promising templates for nanosynthesis. Redox reaction of the nanotube in the presence of silver nitrate leads to the formation of silver nanowire arrays in the pores (pore size of 8 X 8 A ) of the CHQ nanotube. The wires exist as uniformly oriented 3D arrays of ultrahigh density. The driving force for the formation of these nanowires is the free energy gain due to the reduction-oxidation process [154,155]. It was experimentally observed that the resulting nanowire is comprised of four dumbbells, each of which contains two silver atoms, superimposed on one another, and crisscrossed in their length. 

Mesoporous silica has become important owing to its large surface area for adsorption and its uniform nanopores for nanosynthesis. It can also be functionalized to enhance its selectivity and reactivity in adsorption or separation applications.
