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.

Antifriction synergies between an ionic liquid (IL) and nanopowders as additives of an ester base oil were analysed at rolling conditions. For this aim, two nanodispersions based on hybrid combinations of hexagonal boron nitride nanoparticles (h‐BN) or graphene nanoplatelets (GnP) with tri(butyl) ethylphosphonium diethylphosphate ionic liquid as additives in triisotridecyltrimellitate (TTM) base oil and the mixture of TTM and IL were analysed using two tribometer techniques. Film thickness characterisation and tribological tests were performed at rolling conditions [5% slide‐roll‐ratio (SRR)], under 50N and at operating temperatures of 30, 50 and 80°C. Stribeck curves showed that friction coefficients for the prepared lubricants are lower than those found for the TTM, being the best friction behaviour for the hybrid GnP nanolubricant. Furthermore, friction torque loss tests were performed in rolling ball bearings, observing that for the two hybrid nanolubricants lower friction torque values were obtained.
