“…The plots of the experimental UV-vis data obtained with B-C-N films according to Tauc's method give optical bandgaps of 3.4±0.1 and 5.8±0.2 eV. The bandgap of 5.8 eV agree with the reported optical bandgap of h-BN [11,[73][74][75]. Therefore, the optical absorption band with a peak at 200 nm is ascribed to h-BN domains in the B-C-N layers.…”

This work investigates the growth of B-C-N layers by chemical vapor deposition using methylamine borane (MeAB) as the single-source precursor. MeAB has been synthesized and characterized, paying particular attention to the analysis of its thermolysis products, which are the gaseous precursors for B-C-N growth. Samples have been grown on Cu foils and transferred onto different substrates for their morphological, structural, chemical, electronic and optical characterizations. The results of these characterizations indicate a segregation of h-BN and graphene-like (Gr) domains. However, there is an important presence of B and N interactions with C at the Gr borders, and of C interacting at the h-BN-edges, respectively, in the obtained nano-layers. In particular, there is a significant presence of C-N bonds, at Gr/h-BN borders and in the form of N doping of Gr domains. The overall B:C:N contents in the layers is close to 1:3:1.5. A careful analysis of the optical bandgap determination of the obtained B-C-N layers is presented, discussed and compared with previous seminal works with samples of similar composition.

“…Furthermore, if the new phases are prepared from doped nanoparticles of vanadates, their emissions can be tuned, which can be of special relevance for biomedical applications [267], in particular due to the chemical inertness and stability of vanadates [268]. An additional interesting fact is that the pressures required to obtain new phases in compounds like InVO4 [41] are low enough to suggest that these phases could be obtained by ball milling methods [269], which will favour their production in industrial scales.…”

AVO4 orthovanadates are materials of fundamental and technological importance due to the large variety of functional properties exhibited by them. These materials have potential applications such as scintillators, thermophosphors, photocatalysts, and cathodoluminescence materials among others. They are also used as laser-host crystals.Studies at high pressures and temperatures are helpful for understanding the physical properties of the solid state, in particular, the phase behaviour of AVO4 materials. For instance, they have contributed to the understanding of the macroscopic properties of orthovanadates in terms of microscopic mechanisms. A great progress has been made in the last decade towards the study of the pressure-effects on the structural, vibrational, and electronic properties of AVO4 compounds. Thanks to the combination of experimental and theoretical studies, novel metastable structures with interesting * Corresponding author, Email: daniel.errandonea@uv.es, Fax: (34) 96 3543146, Tel.: (34) 96 354 4475 physical properties have been discovered and the high-pressure structural sequence followed by AVO4 oxides has been understood. In this article, we will review highpressure studies carried out on the phase behaviour of different AVO4 compounds. The studied materials include rare-earth orthovanadates and other compounds; for example, BiVO4, FeVO4, CrVO4, and InVO4. In particular, we will focus on discussing the results obtained by different research groups, who have extensively studied orthovanadates up to pressures exceeding 50 GPa. We will make a systematic presentation and discussion of the different results reported in the literature. In addition, with the aim of contributing to the improvement of the actual understanding of the high-pressure properties of ternary oxides, the high-pressure behaviour of orhovanadates will be compared with related compounds; including phosphates, chromates, and arsenates. The behaviour of nanomaterials under compression will also be briefly described and compared with their bulk counterpart. Finally, the implications of the reported studies on technological developments and geophysics will be commented and possible directions for the future studies will be proposed.

“…The nanowires porosity and oxygen-doping (B-O, B-OH) significantly improve the adsorptive desulfurization activity for dibenzothiophene, and adsorption ability for 4,6dimethyldibenzothiophene. h-BNNSs and their hollow shells can be prepared via a bottom-up route with B 2 O 3 and melamine as precursors by adding Mg powders [134]. In particular, Mg powders reduces B 2 O 3 to B element via a combustive reaction with heat release; this thermal energy further causes the decomposition of melamine and provides the condition for the formation of BN structure.…”

Functionalization of boron nitride (BN) materials with hydroxyls has attracted great attention to accomplish better performances at micro- and nanoscale. BN surface hydroxylation, in fact, induces a change in properties and allows expanding the fields of application. In this review, we have summarized the state-of-the-art in developing hydroxylated bulk and nanoscale BN materials. The different synthesis routes to develop hydroxyl BN have been critically discussed. What emerges is the great variety of possible strategies to achieve BN hydroxylation, which, in turn, represents one of the most suitable methods to improve the solubility of BN nanomaterials. The improved stability of BN solutions creates conditions for producing high-quality nanocomposites. Furthermore, new interesting optical and electronic properties may arise from the functionalization by OH groups as displayed by a wide range of both theoretical and experimental studies. After the presentation of the most significant systems and methodologies, we question of future perspective and important trends of the next generation BN materials as well as the possible areas of advanced research. Graphical abstract Hydroxyl functionalization of boron nitride materials is a key method to control and enhance the properties and design new functional applications.
