Boron Influence on Defect Structure and Properties of Lithium Niobate Crystals

open access: yesCrystals, 2021
Defect structure of nominally pure lithium niobate crystals grown from a boron doped charge have been studied by Raman and optical spectroscopy, laser conoscopy, and photoinduced light scattering.

The theoretical study on interaction of hydrogen with single-walled boron nitride nanotubes. I. The reactive force field ReaxFFHBN development [PDF]

open access: yes, 2005
We present a new reactive force field ReaxFFHBN derived to accurately model large molecular and condensed phase systems of H, B, and N atoms. ReaxFFHBN has been tested against quantum calculation data for B–H, B–B, and B–N bond dissociations and for H–B ...

Boron-Based Inverse Sandwich V2B7 Cluster: Double π/σ Aromaticity, Metal–Metal Bonding, and Chemical Analogy to Planar Hypercoordinate Molecular Wheels

open access: yesMolecules, 2023
Inverse sandwich clusters composed of a monocyclic boron ring and two capping transition metal atoms are interesting alloy cluster systems, yet their chemical bonding nature has not been sufficiently elucidated to date.

Absence of boron aggregates in superconducting silicon confirmed by atom probe tomography

open access: yes, 2012
Superconducting boron-doped silicon films prepared by gas immersion laser doping (GILD) technique are analyzed by atom probe tomography. The resulting three-dimensional chemical composition reveals that boron atoms are incorporated into crystalline ...

Dicarba-closo-dodecarborane-containing half-sandwich complexes of ruthenium, osmium, rhodium and iridium : biological relevance and synthetic strategies [PDF]

open access: yes, 2012
This review describes how the incorporation of dicarba-closo-dodecarboranes into half-sandwich complexes of ruthenium, osmium, rhodium and iridium might lead to the development of a new class of compounds with applications in medicine. Such a combination

Glycoconjugates of polyhedral boron clusters [PDF]

open access: yesJournal of Organometallic Chemistry, 2015
Abstract The potential medicinal applications of boron-based compounds have been well established. Among the medicinal applications of boron, its use for the treatment of cancer via boron neutron capture therapy (BNCT) is the most promising. Although a variety of approaches have been evaluated for adequate boron delivery to the cancer tissues for ...

Structural evolution and electronic properties of doped boron clusters Ta2Bn (n = 10 ∼ 20): Ta2B16 and Ta2B18 with strong aromaticity

open access: yesResults in Physics, 2023
In this work, we combine the CALYPSO method with DFT calculations to conduct a comprehensive structural search of Ta2Bn (n = 10 ∼ 20) clusters. Among all the candidate structures obtained by CALYPSO searching, the structures of ground state Ta2Bn ...

Ionic high-pressure form of elemental boron

open access: yes, 2009
Boron is an element of fascinating chemical complexity. Controversies have shrouded this element since its discovery was announced in 1808: the new 'element' turned out to be a compound containing less than 60-70 percent of boron, and it was not until ...
