“…4), micro-Auger spectroscopy [22][23][24], or in cross-sectional transmission electron microscope observation [22],. In fact, XES of metallic B [34] and B2O3 [35] do not explain the characteristic feature observed at 187.5 eV. We think that the additional spectrum comes from B atoms that had diffused in the Ni foil.…”

The electronic structure of monolayer hexagonal boron nitride grown on Ni by the diffusion and precipitation method was studied by x-ray absorption spectroscopy, emission spectroscopy, x-ray photoelectron spectroscopy and micro-ultraviolet photoemission spectroscopy. No indication of hybridization between h-BN π and Ni 3d orbitals was observed. That is, the monolayer h-BN was found to be in the quasi-free-standing state. These results are in striking contrast to those of previous studies in which h-BN was strongly bound to the Ni surface by the orbital hybridization.The absence of hybridization is attributed to absence of a Ni(111) surface in this study.The lattice-matched Ni(111) surface is considered to be essential to orbital hybridization between h-BN and Ni.

“…At present no experimental data are available on boron solid‐state supertetrahedral structures. So the results of the calculations are possible to compare only with the known polyhedral structures, in which BB bonds are in the limits (1.65–1.98 Å), that not much differs from data obtained in the present work.…”

With help of the DFT calculations and imposing of periodic boundary conditions the geometrical and electronic structures were investigated of two-and three-dimensional boron systems designed on the basis of graphane and diamond lattices in which carbons were replaced with boron tetrahedrons.The consequent studies of two-and three-layer systems resulted in the construction of at hree-dimensional supertetrahedral borane crystal structure.T he two-dimensional supertetrahedral borane structures with less than seven layers are dynamically unstable.A tt he same time the three-dimensional superborane systems were found to be dynamically stable.L ack of the forbidden electronic zone for the studied boron systems testifies that these structures can behave as good conductors.T he lowd ensity of the supertetrahedral borane crystal structures (0.9 gcm À3 )i sc lose to that of water,w hich offers the perspective for their application as aerospace and cosmic materials.

“…Boron is a light element in the periodic table, yet one with interesting properties, spanning a wide spectrum of chemical reactivities in the acid–base regime, according to Brönsted‐Lowry and Lewis theories . Boron compounds find applications in various areas of materials science, catalysis, surface chemistry, inorganic–organic synthesis, biochemistry, agriculture, medicine, forestry, and OLEDs . Its presence has also been exploited to emphasize contributions to antibacterial and antifungal properties when doped into titania‐containing nanomaterials .…”

A Systematic Synthetic Study of the Aqueous Chemistry of Binary Boron–Hydroxycarboxylic Acid Systems: Boron Structural Speciation Correlation to the Biotoxicity Profile

In an attempt to delve into the chemistry of boron, whose role in biology still remains unclear, yet its presence and influence is undisputed, research was launched into the structural speciation of B III with physiological binders. The latter molecules involve hydroxycarboxylic glycolic, 2-hydroxy-isobutyric, and citric acids. Their pH-specific reactivity is systematically investigated synthetically in binary and ternary systems of B III , leading to well-defined crystalline materials, [
