Thermal transport properties of boron nitride based ...

2020-3-1 · 3. Bulk boron nitride. The selection of thermoelectric materials relies upon the figure of merit, which further counts on the Seebeck coefficient and conductivity. The Seebeck coefficient depends on the electronic structures near Fermi level and it is perceptive to effective mass, carrier concentration and shape of bands . Bulk boron nitride ...

Synthesis of borophenes: Anisotropic, two …

Although bulk allotropes of carbon and boron differ greatly, small clusters of these elements show remarkable similarities. Boron analogs of two-dimensional carbon allotropes such as graphene have been predicted. Now Mannix et al. report the formation of two-dimensional boron by depositing the elemental boron onto a silver surface under ultrahigh-vacuum conditions (see the Perspective by Sachdev).

High-yield production of few-layer boron nanosheets …

We report ambient electrochemical N 2 fixation at low overpotentials by using two-dimensional (2D) β-boron. The metal-free catalyst afforded both an excellent NH 3 yield rate and faradaic efficiency, approximately two times higher than those of bulk boron. We found that several binding sites, especially those involving icosahedral boron in the 2D material, can indeed catalyze N 2 reduction ...
