The role of substitutional boron in carbon oxidation

Influence of Surface Modification on Combustion Characteristics of Charcoal and Its Performance on Emissions Reduction in Iron Ore Sintering

“…[29][30][31][32] Shirasaki Toru et al found that once the boron content reaches a critical value, the crystallinity of materials deteriorates with the boron content increased, which could potentially serve as the main reason for the influences of B 2 O 3 on combustion of charcoal when its percentage excedded 3%. This is similar to the research findings of Radovic et al 33) The inhibitory effect does not become stronger as the concentration is increased, and the promoting or inhibiting of the B 2 O 3 catalytic effect depends on the combined effects of boron content, distribution and carbon materials properties and the reaction condition. 34) …”

Doping and cluster formation in diamond

“…C (electronegativity 2.55) is less electronegative than N (electronegativity 3.04) and charge therefore is transferred from C to N. Conversely, in the case of p-type doping of diamond, where dopants such as boron (B) or gallium (Ga) have smaller electronegativities than C, charge will be transferred from B (or Ga) to C. This has been determined in B doped graphene layers where there is a r electron localization on the C atoms. 14 Recent electronic structure calculations 15 for silicon (Si) predicted that donor atoms such as P do not just donate an electron to the conduction band as commonly expected. 16 It is rather the charge redistribution within a cluster consisting of the P atom and its four nearest neighbour Si atoms (PSi 4 ) and not the isolated P atom that donates the electron.…”
