The article is devoted to assessing the efficiency of using an electromobile and a car with a fuel cell. Two existing models of the first mass-produced electromobiles were selected for comparison. The relevance of this work is due to the growing requirements for environmental cleanliness of energy carriers used for automobile transport. Obviously, over the coming decades, the main competitors for the mass replacement of traditional motor fuels (gasoline and diesel fuel) will be electricity and hydrogen. This artic...

Water purification is one of the most urgent tasks for solving global problems of fresh water supply and ecology. Special attention is paid to nanoporous membranes, which can be used to purify water from most of the pollutants, such as metal ions, organic molecules, salts and microbes. The development of highly effective nanoporous membranes for water purification is an extremely urgent task. Nanofiltration membranes made from 2D nanomaterials have a huge potential in desalting and purifying to the characteristics...
