Abstract: A method is disclosed for the detection of a His-tagged target biomolecule while said molecule remains in the gel in which it has been separated from other constituents by electrophoresis. The method involves, while the separated His-tagged biomolecule remains in the gel, forming a chelate between the His-tagged molecule, a lanthanide metal ion which exhibits fluorescence, and a sensitizer which enhances the fluorescence of the ion. The gel is then exposed to a u.v. light source to thereby generate a fluorogenic signal indicating the presence of the chelate and, in turn, the His-tagged biomolecule. The fluorogenic signal can then be detected either by direct visualization and/or by other means, such as photographically, e.g., film or charged coupled device (CCD) imaging.

Abstract: The invention concerns a method and a device for treating liquids, such as wastewater. According to the invention the liquid is transported by help of a pump (10) from the lower area of a tank (1) through a vertically directed pipe (3) up to a 180 degree bend (5) located above the water surface and where air is sucked in through openings in the bend. The air-liquid mixture is then guided through a second pipe (6) having its outlet (7) close to the tank bottom (2). In this area the flow is once more linked 180 degrees and is directed through a third pipe (8) ending close to the water surface. Thanks to the linking through the pipe (8), a decrease of the static head is obtained against which the pump (10) operates.

Abstract: A method and apparatus for fabricating an electroplating mask for the formation of a miniature magnetic pole tip structure. The method incorporates a silylation process to silylate photoresist after creating a photoresist cavity or trench in the electroplating mask. The silylation process is performed after a dry etch of the photoresist. Alternatively, silylation is performed after a lithographic patterning of the trench.

Abstract: When iron group, especially high nickel, metal alloys that contain substantial amounts of copper are pickled, a displacement coating of copper that is called a “copper kiss” often forms on the pickled surface from the dissolved copper ions in the pickling solution before the pickling solution can be rinsed away.

In this invention, copper kiss is equally effectively removed by treatment with a mixture of sulfuric acid and hydrogen peroxide, optionally also containing hydrofluoric acid.
