Aluminumtriethoxide were obtained when aluminum powder was refluxed in dehydrated ethanol containing aluminum chloride for 10 ks. It is shown that aluminumtriethoxide powder made in our laboratory coincided with that supplied in commercial market by similar pattern of XRD-analysis, particle size distribution analysis and particle morphology observation. It is considered that aluminumtriethoxide in our laboratory was electrochemically interpreted as corrosion product which has been oxidized in ethanol containing aluminum chloride as catalyst.

It was found that aluminum alkoxide reaction of aluminum alloy 6063 occurs in ethyl alcohol containing aluminum chloride. The reaction is explained by the superimposition of Al/Al 3þ reaction as the anodic reaction and ethanol/ethlate reaction as the cathodic reaction. In an environment containing chloride ions, an Al/AlCl 3 reaction participates in anodic reaction above and then becomes dominant anodic reaction. Rate of aluminum dissolution by the Al/AlCl 3 anodic reaction in ethyl alcohol is accelerated due to the fast system which has low polarization resistance. It is shown that aluminum alkoxide (aluminumtriethoxide) as corrosion product will produce hydrogen peroxide on the way of chain process of productions of ethyl chloride, diethyether and ethyether peroxide. It is also pointed out that the hydrogen peroxide will play a strong cathodic role in further pitting corrosion process.

Fast Electrical Lysis of Cells for Capillary Electrophoresis

et al. 2003

In the past decade, capillary electrophoresis has demonstrated increasing utility for the quantitative analysis of single cells. New applications for the analysis of dynamic cellular properties demand sampling methods with sufficient temporal resolution to accurately measure these processes. In particular, intracellular signaling pathways involving many enzymes can be modulated on subsecond time scales. We have developed a technique to rapidly lyse an adherent mammalian cell using a single electrical pulse followed by efficient loading of the cellular contents into a capillary. Microfabricated electrodes were designed to create a maximum voltage drop across the flattened cell's plasma membrane at a minimum interelectrode voltage. The influence of the interelectrode distance, pulse duration, and pulse strength on the rate of cell lysis was determined. The ability to rapidly lyse a cell and collect and separate the cellular contents was demonstrated by loading cells with Oregon Green and two isomers of carboxyfluorescein. All three fluorophores were detected with a separation efficiency comparable to that of standards. Parallel comparison of electrical lysis to that produced by a laser-based lysis system revealed that the sampling efficiencies of the two techniques were comparable. Rapid cell lysis by an electrical pulse may increase the application of capillary electrophoresis to the study of cellular dynamics requiring fast sampling times.
