· Obtaining Al-based composite materials, doped with Mg, Ni, Cu and Ti, reinforced with plasma-modified nanotubes and BN nanoparticles by methods of powder metallurgy(plasma electric discharge sintering and high-pressure torsion) and melt spinning.
· Composites compression and pull tests at room temperature and extreme temperature (300-500оС). Comparison with test of composites without plasma-modified nanophase.
· Studying damping characteristics of composites based on Al matrix, doped with Mg, Ni, Cu and Ti,
· process of BN nanostructures formation (nanotubes, graphene-like films and mesoporous material) reinforced with BN nanophase in various structure states (after sintering, deformation, annealing) with cyclic interval of temperatures fron normal to extreme.
· Studying process of implantation of various metal ions to BN nanophase surface of various morphology.

The target of the project is boron nitride based nanostructures by chemical vapor deposition method, nanostructures functionalisation and obtaining composite materials based on light metal alloys, reinforced by BN nanostructures.
The research team was one of the first in Russia to master high technology production of various BN nanostructures, which served as a basis for developing new generation of composite materials and biomaterials.
Specifically the team studied the with interaction of borates of alkali and alkaline-earth metals with ammonium.
The team was the first to synthesis nanosize composites consisting of separate BN nanotubes coated with different materials.
The team obtained microcomposites Al/Bn with 145mPa by melt spinning method. They are 2.5 times stronger than Al ribbons.
Al/BNN composites obtained by powder metallurgy method have pull strength 350mPa. It is comparable with some types of construction steels (for example A36) with pull strength of 400 mPa, but the obtained composite materials BN nanotubes reinforced, are 3 times lighter (density 7.85 and 2.5 g/sm3)
The team developed and obtained new types of BN particles based nano containers for antitumor medicine delivery.
