  An electric car is a vehicle powered by one or more electric engines, utilizing energy stored within batteries that are rechargeable. The first register of a usable electrical vehicle dates from 1880s. A hybrid vehicle incorporates two or more different power types, including, e.g., gasoline engines and electric motor. The goal in this work is to present the overall overview of the structure of the electric, hybrid and electric-hybrid vehicles, advantages and disadvantages of these types, the main points to focus when maintaining these and the challenges involved in its production and maintenance.

  The main objective of this study is to remove three neonicotinoid insecticide agents (thiametoxam, acetamiprid, thiakloprid) from model solutions using ferrate and persulfate-based oxidation techniques. In our experiments, an analytical method was developed for HPLC-MS/MS coupled techniques and tests were performed to determine how the molar ratio of the starting target compound/oxidant affects the degree of removal of the target components.
