In this research, various types of nitride additives were incorporated into titanium diboride attaining dense TiB2-based ceramics by field-assisted sintering technique. The addition different additives, namely Si3N4, BN, AlN, and TiN, significantly improved the sinterability TiB2, achieving near fully ceramics. X-ray diffraction analysis microstructural evaluation confirmed presence h-BN compou...

In this work, the percentage of polyethylene (PE) and polypropylene (PP) blend is controlled at 50:50 to make composite by forming a co-continuous structure with hexagonal boron nitride (h-BN). The h-BN wrapped thermoplastic elastomer styrene-ethylene-propylene-styrene (SEPS). This approach enables localized distribution interface PE/PP SEPS phases, allowing construction heat conduction path in...

We present a new force-field potential that describes the interlayer interactions in heterojunctions based on graphene and hexagonal boron nitride (h-BN). The potential consists of a long-range attractive term and a short-range anisotropic repulsive term. Its parameters are calibrated against reference binding and sliding energy profiles for a set of finite dimer systems and the periodic graphe...

Let Dn,k be the family of linear subspaces of R given by all equations of the form 1xi1 = 2xi2 = . . . = kxik , for 1 ≤ i1 < . . . < ik ≤ n and ( 1, . . . , k) ∈ {+1,−1}. Also let Bn,k,h be Dn,k enlarged by the subspaces xj1 = xj2 = . . . = xjh = 0, for 1 ≤ j1 < . . . < jh ≤ n. The special cases Bn,2,1 and Dn,2 are well known as the reflection hyperplane arrangements corresponding to the Coxete...

We show that if f : Bn -IRn is an e-quasi-isometry, with e < 1, defined on the unit ball Bn of Rn, then there is an affine isometry h : Bn -Rn with lIf(x) -h(x)|I < Ce(l+logn) where C is a universal constant. This result is sharp.

The low-temperature adsorption of isolated transition metal adatoms (Mn, Co, and Fe) onto hexagonal boron nitride monolayers on Rh(111) creates a bistable adsorption complex. The first state considerably weakens the hexagonal boron nitride- (h-BN-) substrate bond for 60 BN unit cells, leading to a highly symmetric ring in STM images, while the second state is imaged as a conventional adatom and...

The reaction of N,N'-dibenzyl-2-amino-4-imino-pent-2-ene, nacnac(Bn)H, with 1 or 2 equiv. of MgnBu₂ afforded the homoleptic complex nacnac(Bn)₂Mg. The reaction of nacnac(Bn)H with Mg(N(SiMe₃)₂)₂ yielded nacnac(Bn)MgN(SiMe₃)₂, which reacted with tert-butanol to form nacnac(Bn)MgOtBu. The latter complex crystallizes as an alkoxide bridge dimer and is active in the ring-opening polymerisation of r...

Last decade, numerous giant data center networks are built to provide increasingly fashionable web applications. For two integers m≥0 and n≥2, the m-dimensional DCell network with n-port switches Dm,n n-dimensional BCDC Bn have been proposed. As a generalization of connectivity, structure (substructure) connectivity was recently Let G H be connected graphs. F set whose elements subgraphs G, eve...

We report that few-layer hexagonal boron nitride (h-BN) nanosheets can be produced by using a surface segregation method. The formation of h-BN sheets is via an intermediate boron-nitrogen buffer layer. Our results suggest that surface segregation of boron and nitrogen from a solid source is an alternative approach to tailoring synthesis of h-BN sheets for potential applications such as in grap...
