METHOD FOR STUDYING FERROELECTRIC NANO-CURRENT MANIFESTATIONS OF OXYHYDRATES GELS OF D- AND F-ELEMENTS AND A DEVICE FOR DETECTING SUCH PULSATING FERROELECTRIC NANO-CURRENT MANIFESTATIONS Russian patent published in 2019 - IPC G01N31/00 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to analysis of aggregation stability of nanoparticles of colloidal systems, namely, gels of oxyhydrates of d- and f-elements. For this purpose, the oxyhydrate gel of d- and f-elements is synthesized from oxychloride salts of d- and f-elements while adding caustic soda or ammonia solution. Resultant gel is further placed in a device for detecting pulsating ferroelectric nano-current manifestations. Device is a container in the form of a glass comprising a lower graphite electrode, in which an upper graphite electrode is vertically installed with a gap, connected to each other through a voltage amplifier, wherein one of the electrodes rotates at a constant speed of 0.5 rpm. Voltage between the electrodes is measured for 5–8 hours every day for 70–90 days, and then the obtained measurement results are filtered, the voltage between the electrodes is converted into a ripple current according to formula I=0.2*10^-6*U. Phase portraits of attractors are further constructed in the mathematical program MathLab, portions of the spectra of current pulsations are pointwise increased in the phase portrait, revealing a caustic or electroacoustic hologram, and the hologram structure is studied.

EFFECT: group of inventions provides a visual image of fragments of the structure of water clusters, the analysis of which will allow studying and investigating the structure of gels of oxyhydrates of d- and f-elements at different points in time.
