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 University Chemist Invented a "Line Production" Method of Synthesis of 28 Biologically Active Molecules

A chemist at RUDN University has invented a new method for the synthesis of a large group of complex poly-heterocyclic organic compounds, which draw interest as possible future medications. The researcher turned to a two-step reaction, in which he used affordable and cheap organic reagents and catalysts based on gold, which allowed him to synthesize as many as 28 new molecules. This approach will significantly expand the libraries of biologically active substances. The work was published in Organic & Biomolecular Chemistry.
