چکیده

A chemical active medium on the base of Belousov-Zhabotinsky (BZ) medium was used to design a “chemical diode”. This system, similar to a semiconductor diode, shows unidirectional propagation of chemical pulses and may be possible to be used to construct a massively parallel computational medium. The system of two mesoporous glass plates with ferroin loaded at the surface was covered by BZ solution and maintained propagating excitation waves. The unidirectional propagation was observed when the plates were placed so that the corner of the one plate was close to the plane side of the other plate. The study shows that the important feature of the system is the geometrical arrangement of the plates and the gap distance between them. Computer simulations confirm the experimental results.

One Dimensional Signal Diodes Constructed with Excitable Chemical System

Excitable chemical system can process information coded in excitation pulses. Here we discuss the simplest realization of a chemical signal diode that transmits pulses in one direction only. The construction of such diode just requires a geometrical combination of three areas characterized by different excitability. The proposed construction of chemical signal diode has been tested in numerical...

Diode Laser and Calcium Hydroxide for Elimination of Enterococcus Faecalis in Root Canal

Introduction: The ultimate goal of endodontic treatment is to eliminate the bacterial infection in the root canal system. While mechanical debridement combined with chemical irrigation removes the bulk of microorganisms, residual bacteria are readily detectable in approximately one-half of teeth just prior to obturation. Laser light can be used to destroy bacteria. This in vitro study was perfo...
