Specialists from the Northern (Arctic) Federal University have created a polymer material that is not afraid of ultraviolet radiation, as reported by the press service of the educational institution. Thanks to its resistance to ultraviolet radiation, products made from this material will last longer.
Specialists from NArFU have created a recipe for UV-resistant plastic. Ultraviolet radiation has a significant impact on instruments and equipment operating outdoors. It penetrates the internal structure of polymer materials, destroying double carbon-carbon bonds.
Thanks to the emergence of new materials resistant to ultraviolet radiation, the service life of this equipment can be significantly increased.
This concerns a material used in the 3D printing process. With this method, for example, parts are made for the urgent repair of ships, oil platforms, and equipment in fields located in remote and hard-to-reach areas. However, these parts can be damaged by ultraviolet radiation.
Scientists added lignin to the plastic intended for creating 3D printing filament. Lignin is a polymer found in the cells of deciduous and coniferous plants and makes up almost a third of the dry matter of wood. However, its use remains limited, as lignin is usually burned during cellulose production.
Lignin performs many important functions in wood, protecting it from various physical damages, fungus, dryness, as well as from the negative effects of radiation and oxidative processes.
Specialists from the "Arktika" Center for Collective Use of Scientific Equipment at the Northern (Arctic) Federal University conducted research using ABS plastic, which is widely used in the automotive industry and the production of tools and optical instruments. This material is characterized by high mechanical strength and impact resistance, and is also easily polished.
Earlier, Saratov scientists found an alternative to neural networks. The discovery could significantly simplify and reduce the cost of creating devices capable of performing artificial intelligence tasks in real time.
