UrduScientists from Immanuel Kant Baltic Federal University for the first time obtained cobalt complexes-based self-oscillating gels. Such gels can occasionally change their geometric parameters, thanks to that they can be used for creation of chemomechanical materials, that transform chemical energy into the energy of mechanical oscillations. The emergence of propagating chemical waves inside such gels enables to use material for creation of devices, processing information using cooperation of chemical waves. Results of the research are published in magazine Gels.
