Abstract: Proposed is a biologically active nanochip for treating seeds of agricultural plants in order to improve seed germination conditions and development of plants and for protecting plants from anticipated and averaged adverse conditions. The biologically active nanochip contains a solid porous carrier, such as mineral, clay, turf, or polymer, the pores of which are intended for accommodating nanoparticles of biologically active substances that penetrate the pores when the substances are applied onto the nanochip surface, e.g., by spraying. Alternatively, the biologically active substances can be retained on the surface of the carrier by adhesion. The composition of the biologically active nanochips is selected with reference to anticipated and averaged adverse conditions. Also proposed is a method for application of the biologically active substances onto the surfaces of the biologically active nanochips.

Abstract: A reaction is carried in a gaseous phase between ammonia (NH3) and boron trifluoride (BF3) in a cooled reactor under atmospheric pressure. A boron trifluoride-ammonia complex (NH3.BF3) obtained in this reaction is thermally decomposed at a temperature in the range of 125 to 300° C. into boron nitride and ammonium tetrafluoroborate in accordance with the following scheme: 125-300° C. 4NH3.BF3?BN+3NH4.BF4 BN is then separated from the mixture of BN with 3NH4.BF4 by combining the mixture with deionized water, forming a suspension, and separating the suspended BN nanoparticles by centrifugation.
