Bioconcentration. In aquatic toxicology, bioconcentration is the accumulation of a water-borne chemical substance in an organism exposed to the water. [1][2] There are several ways in which to measure and assess bioaccumulation and bioconcentration. These include: octanol-water partition coefficients (K OW), bioconcentration factors (BCF ...
Tris (pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C6F5)3B. It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC3 core is planar. It has been described as the “ideal Lewis acid ” because of its high ...

Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
The triplet states, 3 S 1, with parallel spins (S = 1, M s = −1, 0, 1) are known as ortho-positronium (o-Ps), and have an energy that is approximately 0.001 eV higher than the singlet. [1] These states have a mean lifetime of 142.05 ± 0.02 ns, [2] and the leading decay is three gammas.
An improved synthesis starts from salts of octahydrotriborate (B 3 H − 8), which is converted to the bromide B 3 H 7 Br − using HBr. Pyrolysis of this bromide gives pentaborane. [7] 5 B 3 H 7 Br − → 3 B 5 H 9 + 5 Br − + 4 H 2. In the U.S., pentaborane was produced on a commercial scale by Callery Chemical Company. Above 150 °C, it ...
