## Recycle rechargeable lithium – ion batteries

Trans Motauto World, Vol. 6 (2021), Issue 1, pg(s) 9-10

Milliards of dollars are set aside for preserving the life on planet Earth and help climate change. Unfortunately, the advances in technology are incapable to help us sort out this vital problem, because the more advanced the technology nowadays is, more irresponsible we become in taking care about consequences after the expiration date of it. It is not only the plastic pollution of ocean of our planet that stops the formation of oxygen but also the irresponsible disposal of lithium-ion rechargeable batteries for smartphones, tablets, computers, electric smart devices and vehicles that are no longer in use, create ionizing radiation and form a radioactive background that affects living and non-living organisms inhabiting our planet. So, when the technology cannot help us, then perhaps the pure science would come to the rescue of preserving ourselves. There are laboratory researches about recycling lithium-ion batteries and here where we are – we are going to implement mathematics, algorithms, indexed arrays(vectors) for describing the benefit of manufacturing the recycling of lithium-ion batteries.

## Мathematical analysis of an electrical circuit

Industry 4.0, Vol. 6 (2021), Issue 1, pg(s) 25-26

There are some research about mathematical analysis of electrical circuits. In time when the scientists are in a deep search of invention new alternative ways for producing renewable energy, mathematic postulates and analysis can help optimize the const ruction of electrical circuits and prevent lost of energy. By themselves, the electrical schemas that represent Electrical circuits are a combination of interconnected electronical elements (components). According to the characteristics of the elements of Electrical schemas they are divided into the following groups: Passive and Active, Linear and Nonlinear, Bipolar and Multipolar. In our research we are going to switch from high to low power and vice versa, so we are going to us the abilities of diodes that switch from on to off state. The different values of low and high power of the electrical circuit will be represented programmatically with a cross-platform application – Arduino Integrated Development Environment and programmable language C++.
