Recently, two-dimensional, layered materials such as graphene and hexagonal boron nitride (h-BN) have been identified interesting for a range of applications. Here, we demonstrate the corrosion prevention applications h-BN in marine coatings. The performance h-BN/polymer hybrid coatings, applied on stainless steel, were evaluated using electrochemical techniques simulated seawater media [marine media]. coating shows an efficient protection with low current density 5.14 × 10(-8) A/cm(2) rate...
Different nanoscale fillers have been used to create composite fluids for applications such as thermal management. The ever increasing loads in now require advanced operational fluids, example, high conductivity dielectric oils transformers. These excellent filler dispersion, conduction, but also electrical insulation. Such that conform this thermal/electrical requirement, and yet remain highly suspended stable state, not synthesized.

Strong in-plane bonding and weak van der Waals interplanar interactions characterize a large number of layered materials, as epitomized by graphite. The advent graphene (G), individual layers from graphite, atomic isolated few other bonded compounds has enabled the ability to pick, place, stack arbitrary compositions build unique which would be otherwise impossible synthesize via known techniques. Here we demonstrate this concept for solids consisting randomly stacked hexagonal boron nitride...
Recently, a lot of interest has been centred on the optical properties hexagonal boron nitride (h‐BN), which similar lattice structure to graphene. Interestingly, h‐BN wide bandgap and is biocompatible, so it potential applications in multiphoton bioimaging, if can exhibit large nonlinear (NLO) properties. However, extensive investigation into NLO have not done far. Here, 2D nanosheets (BNNS) are reported for first time, using 1064‐nm NIR laser radiation with pulse duration 10 ns Z ‐scan...
