An illustration of the 2D boron nitride substrate with imperfections that host tiny nickel clusters. The catalyst aids the chemical reaction that removes hydrogen from liquid chemical carriers, making it available for use as a fuel.

(PDF) Boron Nitride: Properties, Synthesis & …

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).

One‐Step Synthesis of Boron Nitride Quantum Dots: …

Herein, a conceptually new and straightforward aqueous route is described for the synthesis of hydroxyl‐ and amino‐functionalized boron nitride quantum dots (BNQDs) with quantum yields (QY) as high as 18.3 % by using a facile bottom‐up approach, in which a mixture of boric acid and ammonia solution was hydrothermally treated in one pot at 200 °C for 12 h.

Pressure‐Induced Formation and Mechanical …

- Abstract: Boron nitride (BN) hollow nanospheres have been successfully fabricated by pyrolyzing vapors decomposed from ammonia borane (NH{sub 3}BH{sub 3}) at 1300 °C. The final products have been extensively characterized by X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy, and X-ray ...

Pressure‐Induced Formation and Mechanical …

Single crystal cubic boron nitride (cBN) was heteroepitaxially grown on a seed crystal of diamond under static high pressure and high temperature at 5.5GPa and 1,600--1,700 C, respectively, for 10--100 hour.

Preparation of two-dimensional magnetic molecularly ...

New types of two-dimensional (2D) boron nitride (BN) were developed as a 2D scaffold material. After modification with ternary deep eutectic solvents (DES, ChCl-caffeic acid-ethylene glycol), the processed BN was applied to the preparation of magnetic molecularly imprinted polymers (MMIPs). In the p …

Epitaxial Combination of Two-Dimensional Hexagonal …

Hexagonal boron nitride (hBN) and diamond are promising materials for next-generation electronics and optoelectronics. However, their combination is rarely reported. In this study, we for the first time demonstrate the success to direct growth of two-dimensional (2D) hBN crystal layers on diamond substrates by metalorganic vapor phase epitaxy.

Enhancing multi-functional capabilities of boron …

In spite of the outstanding properties of boron nitride nanosheets (BNNSs), their applications may be limited due to counterproductive effect of the unavoidable defects in their structure. As such, tailoring the performance of these 2D nanostructures through defect engineering is of crucial importance. In this regard, we have probed the mechanical and thermal properties of defective BNNSs ...
