Shouldering in B diffusion profiles in Si: Role of di-boron diffusion [PDF]

, 2003
The role of di-boron diffusion in evolution of B diffusion profiles has been investigated. We find that boron pair (B-s-B-i) diffusion can become as important as boron-interstitial pair (B-s-Si-i) diffusion when both boron concentration and annealing ...

van der Waals heterostructures combining graphene and hexagonal boron nitride

Nature Reviews Physics, 2019
As the first in a large family of 2D van der Waals (vdW) materials, graphene has attracted enormous attention owing to its remarkable properties. The recent development of simple experimental techniques for combining graphene with other atomically thin ...

High thermal conductivity in cubic boron arsenide crystals

Science, 2018
Moving the heat aside with BAs Thermal management becomes increasingly important as we decrease device size and increase computing power. Engineering materials with high thermal conductivity, such as boron arsenide (BAs), is hard because it is essential ...

Boron Abundances in Main Sequence B-type Stars: A Test of Rotational Depletion during Main Sequence Evolution [PDF]

, 2001
Boron abundances have been derived for seven main sequence B-type stars from HST STIS spectra around the B III 2066 A line. In two stars, boron appears to be undepleted with respect to the presumed initial abundance.

DFT Study of Planar Boron Sheets: A New Template for Hydrogen Storage [PDF]

, 2009
We study the hydrogen storage properties of planar boron sheets and compare them to those of graphene. The binding of molecular hydrogen to the boron sheet (0.05 eV) is stronger than that to graphene. We find that dispersion of alkali metal (AM = Li, Na,

Boron isotope ratio determination in carbonates /via/ LA-MC-ICP-MS using soda-lime glass standards as reference material [PDF]

, 2010
A new in situ method using LA-MC-ICP-MS (193 nm excimer laser) for the determination of stable boron isotope ratios (δ11B) in carbonates was developed.

Fast and long-lasting Fe(Ⅲ) reduction by boron toward green and accelerated Fenton chemistry.

Angewandte Chemie, 2020
Generation of hydroxyl radicals in the Fenton system (Fe(II)/H 2 O 2 ) is seriously limited by the sluggish kinetics of Fe(III) reduction and fast Fe(III) precipitation.
