The structure of boron in boron fibres
Journal of Materials Science, 1983The structure of noncrystalline, chemically vapour-deposited boron fibres was investigated by computer modelling the experimentally obtained X-ray diffraction patterns. The diffraction patterns from the models were computed using the Debye scattering equation.

A basic overview of essential aspects of the very rich chemistry of boron is discussed to elucidate the structural behavior and chemical properties of boron-containing molecules. Some introductory elements are provided concerning the peculiar chemical properties of boron, which derive from its electronic configuration, bonding orbitals, and ...

Sintering of Boron and Boron Carbide
Journal of Solid State Chemistry, 2000An investigation of sintering kinetics of boron and boron carbide is presented. The influence of the powder size distribution on the temperature dependence of sintering, on reaching a high final density, and on gaining a homogeneous grain size has been shown.

Sillimanite in six granulite-facies, kornerupine-bearing rocks contains 0.035 to 0.43 percent B2O3and 0.02 to 0.23 percent MgO (by weight). Substitution of boron for silicon and magnesium for aluminum is coupled such that the ratio of magnesium to boron is about 0.5.

Boron, the fifth element in the periodic table, is ubiquitous in nature. It is present in food and in surface and ocean waters, and is frequently used in industrial, cosmetic, and medical settings. Exposure to boron and related compounds has been recently implicated as a potential cause of chronic kidney disease in Southeast Asia.

In Vivo and In Vitro Effects of Boron and Boronated Compounds
Journal of Trace Elements in Medicine and Biology, 1998Boron is ubiquitously present in soils and water. Associated with pectin it is essential for vascular plants as a component of cell walls, and it stabilizes cell membranes. It is required for the growth of pollen tubes and is involved in membrane transport, stimulating H(+)-pumping ATPase activity and K+ uptake.

Boron nanodrugs for boron neutron capture therapy
Applied Radiation and IsotopesBoron neutron capture therapy (BNCT) is a promising therapeutic method for malignant tumors, capable of selectively killing tumor cells through nuclear reactions at the single-cell level without damaging surrounding normal cells. With the rapid development of nano-delivery systems in recent years, boron nanodrugs have improved the efficiency of intra ...
