Graphene/hexagonal boron nitride (h-BN) vertical heterostructures have recently revealed unusual physical properties and new phenomena, such as commensurate-incommensurate transition and fractional quantum hall states featured with Hofstadter's butterfly. Graphene-based devices on h-BN substrate also exhibit high performance owing to the atomically flat surface of h-BN and its lack of charged i...

First-principles calculations have been used to investigate the structural and electronic properties of graphene supported on functionalized hexagonal boron nitride (h-BN) with hydrogen and fluorine atoms. Our results show that the hydrogenation and fluorination of the h-BN substrate modify the electronic properties of graphene. Interactions of graphene with fully hydrogenated or fully fluorina...

OBJECTIVE Bilateral audiometric notch (BN) at 4000-6000 Hz was identified as a noise-induced hearing loss (NIHL) phenotype for genetic association analysis in college-aged musicians. This study analysed BN in a sample of US youth. DESIGN Prevalence of the BN within the study sample was determined and logistic-regression analyses were performed to identify audiologic and other demographic fact...

Cu/Ti3SiC2/C/BN/GNPs nanocomposites were prepared by vacuum hot-pressing (HP) sintering and hot isostatic pressing (HIP) sintering methods. Microstructures, mechanical and tribological properties of Cu/Ti3SiC2/C/BN/GNPs nanocomposites were investigated. Microstructures were examined by optical microscopy (OM), X-ray diffraction (XRD) and scanning electron microscope (SEM). Mechanical properties...

The Bayesian network (BN) is a convenient tool for probabilistic modeling of system performance, particularly when it is of interest to update the reliability of the system or its components in light of observed information. In this paper, BN structures for modeling the performance of systems that are defined in terms of their minimum link or cut sets are investigated. Standard BN structures th...

We present density functional calculations of the adsorption of a single Au atom on the h-BN/Rh(111) nanomesh and compare it to Au adsorption on a pure h-BN surface. While Au binds only weakly to pure h-BN (similar to graphene) or to BN at the “wires” of the nanomesh, the subsurface Rh atoms in the “pores” of the nanomesh modify the electronic structure of h-BN considerably and Au adsorbs stron...

Suppose A is a set of non-negative integers with upper Banach density α (see definition below) and the upper Banach density of A + A is less than 2α. We characterize the structure of A+A by showing the following: There is a positive integer g and a set W , which is the union of d2αg − 1e arithmetic sequences1 with the same difference g such that A + A ⊆ W and if [an, bn] for each n is an interv...
