Retention device
(Kosyreva T.F., Vasilyeva M.B., Voeikova O.V.)

The claimed utility model relates to medicine, directly to dentistry and orthodontics, and concerns the design of the retention device. The retention device consists of: a base 1 shortened from the roof of the mouth from photopolymer plastic and two rows of a reinforcing polymer filament 2 with a diameter of 0.35 mm, extending from the vestibular side, then continuing in the base of the device and covered with a photopolymer plastic in the cheek-b side of the crowns teeth 3 without overlapping their cutting edges and occlusal surfaces. The retention device provides an improvement in the result of the retention period after correction of various anomalies of the dentition and anomalies of the teeth.

RUDN chemist synthesized gold-based electrocatalysts

A RUDN chemist has synthesized an electrocatalyst based on gold nanoparticles with organic ligands, which can trigger both hydrogen production reactions and oxygen reduction reactions in fuel cells. The yield of products with the new catalyst was twice as high as when using a traditional platinum-based catalyst.

RUDN University biologist developed new model for analyzing photosynthesis in vivo

A RUDN University biologist has developed a model for the analysis of photosynthesis in vivo. This method allows you to calculate the absorption coefficient of light by chlorophyll, based on its reflectivity. Analysis of light absorption is important for assessing ecosystem productivity, which affects the state of the biosphere and the global climate.
