ABSTRACT

Coalescence of tiny particles for a larger particle is worthwhile. In different materials, building blocks assemble by the orientationally controlled packing to develop shaped mono layers of geometrical shape particles. Orientationally controlled assembling appears to be more favorable in atoms of metallic elements. Atoms arrange in monolayer assembly at first place. Re-crystallization occurs in atoms at solution surface-electrons position in tilting manner nearly half-length above and half-length below to their clamped energy knots. At air-solution interface, when triangle-shaped packets of nano-energy were supplied to atoms of compact monolayer assembly, atoms bound in their shape and size. Blocks of joined triangular shape tiny particles are developed by the tuned bipolar pulses. When a force exerted to perturbed state electrons of face to face atoms joined at unsettled binding point, a block of joined triangle-shaped tiny particles separated into two tiny particles having the same equilateral triangular geometry. At electronically flat solution surface, atoms of tiny particles elongate nearly at equal rate when in re-crystallization state. From the centre of each transitional behavior atom, electrons of east-west poles deal with the exertion of surface force along their opposite poles. Thus, arrays of bound atoms formed a tiny-shaped particle developed in its structures of smooth elements. Such structures of smooth elements are flattened by the forced energy of traveled photons along the air-solution interface. Originally, binding of solid atoms when in neutral state is to be anticipated under the execution of confined inter-state electron dynamics, where they keep ground point below the ground surface. Nevertheless, tiny particles when develop rather than evolve, they come from different regions to assemble their structures of smooth elements adjacent-wise. So, ...
