Magnetic shock absorber
Magnetic shock absorber
(Nevrovsky V.A.)

The utility model relates to the means of vibration protection of objects in various fields of technology, in particular, in engineering and transport. The magnetic shock absorber contains a hollow cylindrical body, open on one side, a cover mounted on this side, through which a rod is passed, to which a piston in the form of a circular magnetic washer is attached. Another magnetic washer is installed on the blind end of the cylindrical cavity. Between the piston and the bottom magnetic washer there is located at intervals a series of identical magnetic washers facing each other with the same poles. In this device, the housing, the stem and the cover are made of ferromagnetic metal and thus form a magnetic core. Inside the case is placed a cylindrical liner of metal having a high specific electrical conductivity. The Eddy currents (Foucault currents) induced in it lead to additional braking of the depreciable object attached to the rod. The technical result is an increase in the damping effect of the magnetic damper.

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 chemist discovered a way to quadruple the speed of toluene photooxidation

A chemist from RUDN University has proposed a new way to control toluene photooxidation using composite catalysts — artificial diamond and titanium dioxide. The discovery refutes the previously existing physical hypothesis about the process of photooxidation of toluene.

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.
