“…Although these nanostructures appear analogous, obtaining nanowires is much more laborious than obtaining nanotubes from a technical point of view. Nanotubes are both used in single-and multi-walled forms according to their application area and characteristics [58]. Furthermore, due to their limited resistance to thermal environment, nano-sized technology demands novel nanostructures with superior thermal resistance.…”

In the present paper, stability analysis of boron nitride and silicon carbide nanotubes/nanowires is carried out using di erent size-e ective theories, nite element method, and computer software. Size-e ective theories used in this paper include Modi ed Couple Stress Theory (MCST), Modi ed Strain Gradient Theory (MSGT), Nonlocal Elasticity Theory (NET), Surface Elasticity Theory (SET), and Nonlocal Surface Elasticity Theory (NSET). As for the computer software, ANSYS and COMSOL multiphysics are used. Comparative results of theories and software and literature are given in the result section. Comparative results are in good harmony. In conclusion, it is clearly seen that the nonlocal elasticity theory yields the lowest results for every modes and structures, while the modi ed strain gradient theory yields the highest results.

“…The The partially ionic B-N bonding in BNNTs is a result of the high electronegativity of N (3.04) atoms as compared to B (2.04). This provides BNNTs with electrical insulating properties and band gaps between 5-6 eV 7,[17][18][19] , making this nanomaterial an excellent candidate for optoelectronics 19 . The first reported synthesis of BNNTs was performed by arc discharge method in 1995 22 .…”

In this study, Boron Nitride Nanotube (BNNT) reinforced Titanium matrix composites are synthesized by Spark Plasma Sintering. Two main challenges directly affecting the mechanical performance of BNNT-metal matrix composites are addressed:(i) Homogenous dispersion of high surface energy BNNTs, and (ii) Controlling interfacial reactions at the metal/nanotube interface. High affinity of acetone with BNNTs and high energy ultrasonication induced the mechanical dispersion and stability of BNNTs in their dispersion. The sintering of Ti (99% relative density) was achieved at 50% less processing temperature than those used in conventional sintering to minimize interfacial reactions when reinforced with BNNTs. The reduction of temperatures in addition to the reduction (by 91%) in processing times was shown to control reaction phases. Bulk compressive yield strengths of Ti-BNNT sintered at low (750 o C) and high (950 o C) temperatures were improved by 21% and 50% respectively, as compared to Ti alloy without reinforcement. Twin boundaries, pinning of dislocations by BNNTs, and crack bridging were strengthening mechanisms identified in the composites. vi TABLE OF CONTENT CHAPTER

“…A variety of hybrid/hetero structures of hBN with graphene have been demonstrated experimentally too [30][31][32][33][34][35][36]. The structural, electronic, magnetic, and optical properties of hBN nanotubes [37][38][39][40][41][42][43][44][45][46] and nanoribbons [46][47][48][49][50][51][52] have been a subject of investigation in semiempirical and first principles studies. Intensive studies have been also undertaken by theorists to reveal and understand the properties of hBN/graphene hetero/hybrid structures [53][54][55][56][57][58][59][60].…”
