General description

Aluminum oxide (alumina, Al2O3), a metal oxide,[1] is a common raw material for manufacturing ceramics. It is a good electrical insulator that shows stability at high temperature and resistance to chemicals.[2] Alumina is an important source for aluminum and can be prepared from high-alumina ladle furnace refining slag.[3] It can enhance the reaction rate of aldose to ketose conversion by Lobry de Bruyn–Alberda van Ekenstein transformation.[4] It is a key constituent of NOx storage catalysts (NSC), which are employed to get rid of nitrogen oxides from the exhaust gas of lean burn engines.[5] Its surface passivation characteristics on crystalline silicon makes it a vaiable candidate in silicon solar cell production.[5]

Application

Aluminum oxide was used in the disposable alumina columns, to determine the adenylyl cyclase (AC) activity during the interaction of 2,3-O-(2,4,6-trinitrophenyl)-substituted nucleoside 5-triphosphates (TNP-NTPs)with VC1:IIC2 (purified catalytic subunits of membranous AC).[6] It may be used as a dopant to produce optical fiber amplifiers and high-power fiber lasers.[7]

Adenylyl cyclases (ACs) catalyze the conversion of ATP into the second messenger cAMP and play a key role in signal transduction. In a recent study (Mol Pharmacol 70:878-886, 2006), we reported that 2',3'-O-(2,4,6-trinitrophenyl)-substituted nucleoside 5'-triphosphates (TNP-NTPs) are potent inhibitors (K(i)
