Abstract: Hexagonal boron nitride (h‐BN) has emerged as a strong candidate for two‐dimensional (2D) material owing to its exciting optoelectrical properties combined with mechanical robustness, thermal stability, and chemical inertness. Super‐thin h‐BN layers have gained significant attention from the scientific community for many applications, including nanoelectronics, photonics, biomedical, anti‐corrosion, and catalysis, among others. This review provides a systematic elaboration of the structural, electrical, mechanical, optical, and thermal properties of h‐BN followed by a comprehensive account of state‐of‐the‐art synthesis strategies for 2D h‐BN, including chemical exfoliation, chemical, and physical vapor deposition, and other methods that have been successfully developed in recent years. It further elaborates a wide variety of processing routes developed for doping, substitution, functionalization, and combination with other materials to form heterostructures. Based on the extraordinary properties and thermal‐mechanical‐chemical stability of 2D h‐BN, various potential applications of these structures are described.

Abstract: The synthesis of inorganic nanoparticles using continuous hydrothermal flow synthesis (CHFS) reactor systems is an up-and-coming process to manufacture high-quality nanomaterials with singular control of the experimental parameters on the scale of seconds as opposed to hours. VO2-based systems manufactured using an autoclave reactor lack scalability, and current commercial products feature particle sizes too large for feasible application. In this paper, the detailed implementation of a CHFS system that can operate at and above supercritical water conditions (22.06 MPa at 374˚C) is described. Control over the CHFS system’s temperature, flow rate, and precursor concentration parameters allowed the tunability of size, crystallinity, and shape of VO2 nanoparticles to be investigated across seven studies. The resulting VO2 nanoparticles were characterized for size, shape, morphology, and crystallinity using dynamic light scattering (DLS), scanning electron microscopy (SEM), and x-ray diffraction (XRD). This investigation resulted in new operating procedures that enable the synthesis of high-quality, uniform, spherical, and pure M-phase VO2 nanoparticles under 50 nm in diameter in the residence time of a few seconds. Additionally, the procedure described in this paper is performed in a single step, thus eliminating the tedious post-annealing process.
