BH) max can be graphically defined as the area of the largest rectangle that can drawn in the second quadrant of the B-H loop. The maximum energy product is defined based on the magnetic hysteresis saturation loop ( B - H curve), in the demagnetizing portion where the B and H fields are in opposition.
[10] The spectrum of boron monohydride includes a molecular band for the lowest electronic transition X 1 Σ + → A 1 Π with a band head at 433.1 nm (for 0→0) and 437.1 (for 0→1) [3] The spectrum contains P, Q, and R branches. [10] Although BH is a closed shell molecule, it is paramagnetic independent of temperature. [11]
Ball-and-stick model of the tetrahydroborate anion, [BH 4] −. Borohydride refers to the anion [B H 4] −, which is also called tetrahydridoborate, and its salts. [1] Borohydride or hydroborate is also the term used for compounds containing [BH 4−n X n] −, where n is an integer from 0 to 3, for example cyanoborohydride or cyanotrihydroborate [BH 3 (CN)] − and triethylborohydride or ...
The problems related to the distance of Confins to downtown Belo Horizonte were lessened by recent projects such as the improvement of the highway that links the city center to the airport (MG-10 highway), part of a larger project called Linha Verde (Green Line), which seeks to reduce the time needed to reach the airport.

B 10 H 14 + 2 L → B 10 H 12 L 2 + H 2. These species, which are classified as "arachno" clusters, in turn react with acetylene to give the "closo" ortho-carborane: B 10 H 12 ·2L + C 2 H 2 → C 2 B 10 H 12 + 2 L + H 2. Decaborane(14) is a weak Brønsted acid. Monodeprotonation generates the anion [B 10 H 13] −, with again a nido structure.
Pentaborane(9) is an inorganic compound with the formula B 5 H 9.It is one of the most common boron hydride clusters, although it is a highly reactive compound.Because of its high reactivity with oxygen, it was once evaluated as rocket or jet fuel.
Tetrahydroxyborate is an inorganic anion with the chemical formula [BH 4 O 4] − or [B(OH) 4] −. It contributes no colour to tetrahydroxyborate salts. It is found in the mineral hexahydroborite, Ca(B(OH) 4) 2 · 2 H 2 O, originally formulated CaB 2 O 4 · 6 H 2 O. [2] It is one of the boron oxoanions, and acts as a weak base.
The Vivarail D-Train is a family of multiple units remanufactured by Vivarail for the British rail network. They are converted from London Underground D78 Stock , originally manufactured between 1978 and 1981 by Metro-Cammell .
