“…“Graphene analog” hexagonal boron nitride nanosheets (h‐BNNSs) have been the center of attention for the last few years [16] . The mechanical, dielectric, electronic, and thermal propertiesof the h‐BNNSs proved to be better than their bulk counterpart [17] . The h‐BNNSs demonstrate the potential ability to succeed in large applications such as in electronic and optoelectronic devices as it is characterized by an abundance of good mechanical, optical, and dielectric properties [18] …”

Hexagonal boron nitride nanosheets (h‐BNNSs), the geometry similar to that of two‐dimensional (2D) graphene has engrossed substantial attention due to its promising superior thermal, electrical, and dielectric properties for both fundamental studies as well as potential applications. Due to the strong covalent bond interactions in bulk hexagonal boron nitride (h‐BN), the high yield synthesis of large‐size h‐BNNSs is still a challenging task. In this report, a facile and innovative mixed solvent was carried out in the liquid phase exfoliation method via ultra‐sonication to obtain h‐BNNSs in large quality. The mixed solventconsisting of a mixture of Isopropyl alcohol (IPA) and De‐ionized (DI) water (in 3 : 7 ratio) is used for the highly efficient and cost‐effective synthesis of h‐BNNSs. In an optimized condition, the production yield of h‐BNNSs is approximately 90 % with a concentration of 0.6mg/mL. Here, the Lewis acid‐base interaction mechanism is responsible for the exfoliation of h‐BN due to the electron deficient boron atoms. The exfoliated ultra‐thin h‐BNNSs show better results, which is confirmed by Raman spectroscopy. Hence, our study provides a simple, large scale and economical exfoliation approach for the preparation of h‐BNNSs in next generation potential applications.

“…[11] BN nanosheet has also more adsorption force than BN bulk, and its adsorption capacity is about 2 times more than that of h-BN. [12] BNNSs are stable in air up to 850°C and do not oxidize up to 700°C, while the oxidation onset temperature is slightly higher for two-layer and three-layer BNNSs. [13] Enhancing the solubility, absorption, biocompatibility, targeted delivery and controlled release of drugs are some advantages of the nanotechnology based drug delivery methods over the traditional procedures.…”

Fluorouracil (5-FU) is one of the most essential drugs, and widely used to treat different types of cancers. However, direct injection of 5-FU causes many inevitable side effects, and therefore, the design of new and targeted drug delivery methods can reduce such undesirable effects. In the present work, density functional theory methods at B3LYP-D3(BJ)/6-31 g* level of theory were used to study the pristine and Al, Ga, P and As doped monolayer boron nitride (BN) nanosheets, as possible adsorption substrates for modern and targeted nanotechnology based drug delivery methods. Natural bond orbitals and quantum theory of atoms in molecules analyses were further used to reveal the physicochemical nature of the adsorption process. It was found that, adsorption process is endothermic in all studied cases, and the interactions energies are in the range of physisorption for pristine, P and As doped BN nanosheets, whereas, the chemical absorption of the 5-FU on Al and Ga doped nanosheets was obtained with adsorption energies of À 45.7 and À 46.3 kcal/mol, respectively. The calculated solvation energies also show that, the dissolution of the 5-FU/nanosheet complexes in water is more than the pristine nanosheets. The overall results confirm the great potential of the studied nanosheets and specially Al and Ga doped BNNSs as promising drug delivery substances in modern targeted drug delivery methods for 5-FU drug.

“…Boron nitride (BN) nanostructures are boron nitride (BN) based materials consisting of stacked hexagonal BN layers that are assembled in sheets or tubes (case of BN nano-sheets or BN nanotubes, respectively) with high aspect ratio [1][2][3][4]. These low-dimensional nanostructures are structurally identical to graphene or carbon nanotubes (CNTs) [5,6], and exhibit many fascinating properties for advanced applications [1][2][3][4][5][6][7][8][9]. However, in contrast to graphene or CNTs, which are conductor or semiconductors, BN nanostructures are electrically insulator [5,6].…”

“…However, in contrast to graphene or CNTs, which are conductor or semiconductors, BN nanostructures are electrically insulator [5,6]. This makes them a hot research topic in different applications including dielectric substrates, far-ultraviolet light-emitting, high performance electronic devices and smart coating [1][2][3][4][5][6][7][8][9]. Concerning smart coating, and except for some BN nanotubes which are super-hydrophobic [10,11], the other BN nanostructures including nano-sheets [12][13][14], and few atomic layers [15], have shown a good hydrophobicity character (with contact angle (CA) around 100-120 • ).…”

Boron nitride nanosheets (BNNS) consisting of 2D hexagonal boron nitride nano-layers were deposited, onto silicon substrates, via chemical vapour deposition process at 1000 • C. The BNNS were functionalized in argon plasma admixed with sulfur hexafluoride (SF6) or tetrafluorethane (C2H2F4) gases. Scanning electron microscope (SEM), High resolution transmission electron microscope (HRTEM), X-ray photoelectron spectroscopy (XPS), and Water contact angle (WCA) measurements were used to characterize the BNNS before and after plasma modification. Significant changes in the surface features, upon plasma treatments of the BNNS, were noticed during scanning and transmission electron microscopy examinations. The XPS analyses revealed an extensive surface fluorination in the case of Ar/SF6 plasma, while formation of fluoro-carbon layer coating on the surface of BNNS was noticed in the case of Ar/C2H2F4 plasma. Furthermore, the plasma treatments made BNNS super-hydrophobic with a contact angle as high as 167.9 • compared to 118.2 • for the untreated BNNS. The wettability of the nanostructures, as measured form the water contact angle measurements, is discussed by referring to changes in surface chemistry and morphology after plasma treatment. The stability of BNNS at high temperatures, coupled with plasma treatment can make this material a potential candidate as super-hydrophobic coating for self-cleaning application at the industrial level.
