Abstract

Periodic phenomena are widespread in nature, ranging from the planet motion to biochemical cycles which rule living systems. Surprisingly, the existence of in vitro chemical oscillations was only recently accepted as possible by chemists community. Self-sustained concentration oscillations in chemical processes are now well understood within the solid framework of the far from equilibrium thermodynamics and the attention has been shifted to elucidate different mechanisms at the origin of these periodic dynamics. Over the last three decades a great deal of mastery has been developed in designing chemical oscillator by means a systematic algorithms. Nevertheless the whole landscape of inorganic oscillators is circumscribed to a confined number of chemicals. Essentially the wide set of the known chemical clocks involve metal ions, oxi–halogen ions, being iodate, bromate and chlorite the most common. The discovery of new oscillators is an encouraging opportunity for testing general theory and exploring new scenarios by which periodic behaviors may occur. These studies also promise to facilitate the approach to more complex dynamics widespread in the biological world and in the realm of applicative research. Here we report an original chemical oscillator which involves a completely new chemistry based on boron-hydrides salts. Understanding complex dynamics in boron-hydrides hydrolysis marks a path-breaking goal in the hydrogen basic research based on boron–hydrides.
