“…It makes boron form the B 12 icosahedra structural unit through a unique 3-center 2-electron bond, based on which, boron has unique physical and chemical properties such as low density, high melting point, extreme hardness, and high chemical stability. [49][50][51] It has been widely used as a dopant in the semiconductor industry and its compounds play essential roles in light-weight structural materials. [52][53][54] Inspired by the first theoretical work on boron nanotubes 55 and the prediction of high electrical conductivity of 1D boron nanostructures, [56][57][58] the developments in 1D boron nanostructures including nanotubes, nanowires, nanobelts, and nanocones have attracted great attention from both science and engineering communities in recent years.…”

One-dimensional (1D) boron nanostructures are very potential for nanoscale electronic devices since their physical properties including electric transport and field emission have been found very promising as compared to other well-developed 1D nanomaterials. In this article, we review the current progress that has been made on 1D boron nanostructures in terms of theoretical prediction, synthetic techniques, characterizations and potential applications. To date, the synthesis of 1D boron nanostructures has been well-developed. The popular structures include nanowires, nanobelts, and nanocones. Some of these 1D nanostructures exhibited improved electric transport properties over bulk boron materials as well as promising field emission properties. By current experimental findings, 1D boron nanostructures are promising to be one of core materials for future nanodevices. More efforts are expected to be made in future on the controlled growth of 1D boron nanostructures and tailoring their physical properties.

“…The main pure phases of boron that could be successfully prepared experimentally and have been include the thermodynamically stable rhombohedral boron (α-rhombohedral and β-rhombohedral), tetragonal boron (α-tetragonal and β-tetragonal), , orthorhombic boron (γ-B 28 ) stable at high-pressure . The unique structure and bonding method of boron give it several distinctive properties, low density (2.364 g cm –3 ), high melting point (over 2300 °C), and high hardness (close to diamond) , and so on. These properties result in excellent chemical stability, high thermal conductivity, and high electrical conductivity, which all boost boron an attractive material for high-temperature coatings, lightweight materials and high-temperature semiconductor electronic devices.…”

The development on mono-element nonmetallic materials is of great significance for achieving low-cost and highperformance conversion and storage of clean and renewable energy. As number of mono-element groups, boron has owned the intrinsic unique electronic deficiency and diversified crystal structures, and displayed the utilization potential in the energy conversion and storage fields. Especially, the various boron nanomaterials have attracted extensive attentions on the basis of their several properties, such as metallic and semiconductor characteristics, electrocatalytic activity, exceptional mechanical strength and thermal stability, which could meet the increasing demands for efficient energy conversion and storage materials. In this review, the recent advances of mono-element boron nanomaterials for energy conversion and storage have been summarized comprehensively. The experimental preparation methods, as well as physical and chemical and properties of boron nanomaterials are analyzed based on the classification of material morphologies. In addition, a special focus has been proposed on their plentiful applications as active/catalytic electrode materials in energy storage devices, and as electrocatalysts or photocatalysts in energy conversion systems. Finally, the challenges and potential opportunities have been discussed for mono-element boron nanomaterials in energy conversion and storage.

“…Recent neutron detection devices are based on boron (B) and B-based compounds as converter elements alternative to 3 He not only because of their more abundance but also due to their outstanding physical properties. Among these, there are high hardness (comparable to diamond), high stability of B-B bonds, corrosion resistance, low densities, high melting temperatures, high reflectance in the extreme ultraviolet (40 nm-200 nm), as well as tunable thermal and electric transport properties depending on the dimensionality (thin films, nanowires, boron fullerene, borophene) [21][22][23][24]. Moreover, 10 B has a very high capture cross section for thermal neutrons (3840 barn) [5,6].…”

Neutron applications and detection are of paramount importance in industry, medicine, scientific research, homeland security, production of extreme UV optics and so on. Neutron detection requires a converter element that, as a result of its interaction with neutrons, produces reaction products (mainly charged particles) whose detection can be correlated with the neutron flux. Reduced availability and increased cost of the most used converter element, 3He, have triggered research efforts for alternative materials, proper deposition methods and new detector architectures. 10B converter is a valid alternative to 3He thanks to its high thermal neutron cross section and relatively high Q value. In this paper we report on the room temperature Pulsed Laser Deposition (PLD) of high quality and uniform 10B films with the expected density, different thickness values (0.5, 1.0, 1.2, 1.5 and 2.0 μm) and uniform thickness over a circular area of about 30 mm in diameter. Additionally, they are adherent to the substrate with a negligible presence of contaminants. The conversion properties of such 10B coatings coupled to a Si solid state detector are studied upon exposure to a neutron flux from an Am-Be neutron source (2.2·106 n/s). The experimental results, compared with spectra simulated by using a GEANT4 code, present a good agreement and efficiencies of the order of a few percent.
