A single-wheel driving mechanism for floor transport vehicles is comprised of a gearing housing with at least one gear stage, a flanged-on drive motor, and a driven running wheel. A GOV layer can be inserted not only at the head of the coded bit stream but at an arbitrary position in the coded bit stream. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles. The substrate layout of the transceiver is configured so that the parallel ports and the serial ports are on the outer perimeter.
