Piperonyl butoxide (PBO) is a pale yellow to light brown liquid [1] organic compound used as an adjuvant component of pesticide formulations for synergy.That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.

Zylon (IUPAC name: poly(p-phenylene-2,6-benzobisoxazole)) is a trademarked name for a range of thermoset liquid-crystalline polyoxazole. This synthetic polymer material was invented and developed by SRI International in the 1980s and manufactured by Toyobo. [2] In generic usage, the fiber is referred to as PBO. [3]
The mode can be determined by the sign of the threshold voltage (gate voltage relative to source voltage at the point where an inversion layer just forms in the channel): for an N-type FET, enhancement-mode devices have positive thresholds, and depletion-mode devices have negative thresholds; for a P-type FET, enhancement-mode have negative ...

1,2,3,4-Butanetetracarboxylic acid is an organic compound with the formula HO 2 CCH 2 CH(CO 2 H)CH(CO 2 H)CH 2 CO 2 H. It is one of the simplest stable tetracarboxylic acids. The compound exists as two diastereomers, meso and the (R,R)/(S,S) pair. All are white solids. The compound is produced by oxidation of tetrahydrophthalic anhydride. [1]
From January 2008 to April 2011, if you bought shares in companies when William C. Steere, Jr. joined the board, and sold them when he left, you would have a -2.9 percent return on your investment, compared to a -7.3 percent return from the S&P 500.
Plattnerite is an oxide mineral and is the beta crystalline form of lead dioxide (β-PbO 2), scrutinyite being the other, alpha form. It was first reported in 1845 and named after German mineralogist Karl Friedrich Plattner. Plattnerite forms bundles of dark needle-like crystals on various minerals; the crystals are hard and brittle and have ...
