Properties of BN

Coatings of h-BN are used in a wide range of applications due to the extraordinary properties of BN. BN coatings are used in the steel and iron... 

The excellent insulating and dielectric properties of BN combined with the high thermal conductivity make this material suitable for a huge variety of applications in the electronic industry [142]. BN is used as substrate for semiconductor parts, as windows in microwave apparatus, as insulator layers for MISFET semiconductors, for optical and magneto-optical recording media, and for optical disc memories. BN is often used as a boron dopant source for semiconductors. Electrochemical applications include the use as a carrier material for catalysts in fuel cells, electrodes in molten salt fuel cells, seals in batteries, and BN coated membranes in electrolysis cells for manufacture of rare earth metals [143-145]. 

Single-walled carbon nanotubes are known to possess extraordinary strength.138 Mechanical properties of BN nanotubes would be worthy of exploration. Unlike carbon nanotubes, BN nanotubes are predicted to have stable insulating properties independent of their structure and morphology. Thus, BN tubes can be used as nano-insulating devices for encapsulating conducting materials like metallic wires. Filled BN nanotubes are expected to be useful in nanoscale electronic devices and for the preparation of nano-structured ceramics. 

Properties of inorganic nanotubes such as those of MoS2 have been investigated to some extent. However, by and large, there is much to be studied with respect to the electronic, optical and other properties of most of the inorganic nanotubes. Properties such as sorption, hydrogen storage and catalytic activity are worthy of exploration. Mechanical properties of BN, B-N-C and related nanotubes are also worthy of study.

Conjugation of HYNIC and BN for the preparation of Tc-EDDA/ HYNIC-[Lys ]BN modifies the lipophilic and pharmacokinetic properties of BN, producing a radiopharmaceutical with low hepatobiliary clearance and high renal excretion. This is an important observation, because most of the Tc labelled BN analogues have a tendency to accumulate in the liver and intestine as a result of hepatobiliary clearance [11.17-11.20], leading to interference during the detection of BN/GRPr positive cancers and their metastases in the abdominal areas.

Combustion Synthesis of Nitride-Based Ceramics 71 Table 2.2 Some properties of BN-based ceramics. 

The synthesis of composite structures from Ni/Ni3P/Co2P207 components has recently been reported [94]. The electrical, optical and thermal properties of BN nanotubes are reported to be drastically different to those of carbon nanotubes [88]. The properties of Pnanotubes (Chapter 4.1) might prove to be even more interesting. While the flat sheets of graphene can be bent into carbon nanotubes, the puckered sheets which are present in black P would seem less likely candidates for similar treatment. 

The application of the elongation method to nanotube systems is a first step towards systems too expensive for any conventional quantum chemical method because of the large number of atoms. In this subsection, the NLO properties of several Boron Nitride/Carbon nanotubes are calculated by the elg-FF method to investigate carbon-doped effect on the NLO properties of BN nanotubes.
