A hexagonal boron nitride nanosheet (BNNS) is an atomic-thick 2D material that exhibits many interesting properties such as high chemical stability and excellent mechanical and thermal properties. In Chapter One, the authors introduce two methods for the exfoliation of BNNS from hexagonal boron nitride (hBN). Then, methodologies for the surface functionalisation and nanocomposite construction are demonstrated by two BNNS based nanocomposites. The catalytic performance of the BNNS based nanocomposites is also evaluated and discussed in detail. Chapter two evaluates the formation of rolled hexagonal boron nitride nano-sheets (h-BN nanoscrolls) on their unique morphology, magnetic properties and applications. Due to the high chemical and thermal stabilities, as well as atomically smooth surfaces with free of dangling bonds, hBN has been used as barriers, passivation and support layers in 2D electronic devices, to maximise the electrical and optical characterisation of 2D materials. However, there still remains a challenge in obtaining large-area and high-quality hBN film for real 2D electronic devices. Chapter Three focuses on chemical vapor deposition (CVD), a promising method to overcome these limitations. Chapter Four discusses how a boron doped armchair graphene ribbon has been shown by cyclic voltammetry to be a potential catalyst to replace platinum, however the reaction catalysed was not identified. The authors use density functional calculations to show the reaction catalysed is likely dissociation of HO2. Chapter Five reveals a novel and industrially feasible route to incorporate boron nitride nanoparticles (BNNPs) in radiation-shielding aerospace structural materials. Chapter Six deals with the preparation and characterisation of boron nitride nanotube (BNNT)-reinforced biopolyester matrices. The morphology, hydrophilicity, biodegradability, cytotoxicity, thermal, mechanical, tribological and antibacterial properties of the resulting nanocomposites are discussed in detail. Chapter Seven presents theoretical estimations regarding the compressive buckling response of single walled boron nitride nanotubes (SWBNNTs), which have a similar crystal structure as single walled carbon nanotubes (SWCNTs). Moreover, SWBNNTs have excellent mechanical, insulating and dielectric properties. Finally, Chapter Eight shows how the different exchange mechanisms can be distinguished and measured by studying solid films where part of the 3He is replaced by immobile Ne atoms. The authors also show how the formation energy of vacancies and vacancy tunneling frequency can be obtained from NMR studies at high temperature.

The nitrides and carbides of boron and silicon are proving to be an excellent choice when selecting materials for the design of devices that are to be employed under particularly demanding environmental and thermal con- tions. The high degree of cross-linking, due to the preferred coordination numbers of the predominantly covalently bonded constituents equalling or exceeding three, lends these non-oxidic ceramics a high kinetic stability, and is regarded as the microscopic origin of their impressive thermal and mechanical durability. Thus it does not come as a surprise that the chemistry, the physical properties and the engineering of the corresponding binary, ternary, and even quaternary compounds have been the subject of intensive and sustained efforts in research and development. In the five reviews presented in the volumes 101 and 102 of "Structure and Bonding" an attempt has been made to cover both the essential and the most recent advances achieved in this particular field of materials research. The scope of the individual contributions is such as to address both graduate students, specializing in ceramic materials, and all scientists in academia or industry dealing with materials research and development. Each review provides, in its introductory part, the chemical, physical and, to some extent, historical background of the respective material, and then focuses on the most relevant and the most recent achievements.

Boron nitride was first produced in the 18th century and, by virtue of its extraordinary mechanical strength, has found extensive application in industrial processes since the 1940s. However, the more recent discovery that boron nitride allotropes are as structurally diverse as those of carbon (e.g. fullerenes, graphene, carbon nanotubes) has placed this material, and particularly its low-dimensional allotropes, back at the forefront of modern material science. This book provides a comprehensive history of this rapid rise in the status of boron nitride and boron nitride nanomaterials, spanning the earliest examples of three-dimensional boron nitride allotropes, through to contemporary structures such as monolayer hexagonal boron nitride, boron nitride nanomeshes, boron nitride nanotubes and the incorporation of boron nitride into cutting-edge van der Waals heterostructures. It specifically focuses on the properties, applications and synthesis techniques for each of these allotropes and examines how the evolution in boron nitride production methods is linked to that in our understanding of how low-dimensional nanomaterials self-assemble, or ‘grow’, during synthesis. The book demonstrates the key synergy between growth mechanisms and the development of new, advanced nanostructured materials.

Nanostructured materials such as nanotubes exhibit properties significantly different from their bulk counterparts. The effect of the length scale on nanostructure material properties, in general, is briefly discussed. Boron nitride nanotubes (BNNTs) are wide-bandgap (Bandgap: ∼5 eV) semiconductor materials with attractive electrical, optical, mechanical, and thermal properties. The structure of BNNTs is delineated followed by a description of their main methods of synthesis. Electrical, mechanical, optical, and thermal properties of BNNTs are discussed and contrasted with those of the carbon nanotubes (CNTs). It is shown that the properties of BNNTs rival, if not exceed CNTs in several areas. It is envisaged that with further research, BNNTs will find applications in nanoelectromechanical systems, as ultraviolet light sources, in composite materials, and for storing gases.
