    Study examines the problem of development of novel nanomaterials serving for boron 10B isotope delivery agents in Boron-Neutron-Capture-Therapy (BNCT). For this purpose, there is done a mini-review on Nano powder boron compounds especially prospective for BNCT; magnetic Nano carriers of the therapeutically active agents in general, delivery of which can be controlled by using of an external magnetic field; as well as methods of synthesis of nanocomposites comprising components of both kinds. Based on recent literature analysis, boron nitride and boron carbide Nano powders doped with ferromagnetic iron oxide nanoclusters are recommended for BNCT as effective delivery agents with good biocompatibility

    Nanocomposites based on boron carbide B4C are hard materials with wide field of applications in modern technologies. A system of first-order ordinary differential equations that simulates the process of chemical synthesis of nanopowders of B4C–TiB2 compositions containing titanium diboride (TiB2) as an additional phase is suggested and resolved numerically for a typical ratio of reaction constants. Reagents and products concentrations are found as time-functions. In this way, the optimal route of production technology of boron carbide-based nanomaterials can be identified

    Boron carbide is known as a hard material; it possesses a unique complex of physical-mechanical properties and has diverse applications in industries. An expansion of its field of uses stems from the creation of boron carbide matrix nanocomposite materials. In view of this perspective, an effective liquid-charge synthesizing method for their components in nanopowder form has been proposed. This paper provides a focused review on advanced boron carbide matrix ceramic and metal-ceramic nanocomposites recently obtained by the authors using this method. Particular attention is paid to the characterization of boron carbide nanocomposites, including some ceramic borides, metallic alloys and also other metal-ceramic composites
