The Authors suggest a new method, elaborated by their own, for long-term antiarrhythmic stimulation. They used ambulatory electrocardiography in order to evaluate the results. It consists of a radio frequency device for synchronization and stimulation, and allows the scanning stimulation of all the cycle of tachycardia, with automatic search for the zone of interruption. The stimulatory is carried by the patient, who must set it in motion at the onset of the tachycardia. Preliminary results show the efficacy of the method; Holter monitoring seems to be the best guide to the development of a satisfactory implantable automatic tachycardia-terminating pacemaker.

A recyclability perspective is essential in the sustainable development of energy storage devices, such as lithium-ion batteries (LIBs), but the development of LIBs prioritizes battery capacity and energy density over recyclability, and hence, the recycling methods are complex and the recycling rate is low compared to other technologies. To improve this situation, the underlying battery design must be changed and the material choices need to be made with a sustainable mindset. A suitable and effective approach is to utilize bio-materials, such as paper and electrode composites made from graphite and cellulose, and adopt already existing recycling methods connected to the paper industry.
