    摘要： This invention provides E.M.I. gaskets for electrically shielding and environmentally sealing the space between two surfaces which comprises a metallic electrically conductive deformable structure adapted for forming electrical contact with said surfaces and/or providing electrical shielding in the space between said surfaces; and a gel material for sealing the space between said surfaces having a cone penetration value of about 100 to about 350 (10.sup.-1 mm) and an ultimate elongation of at least 200% and being present in sufficient amount and positioned to provide environmental seal between said surfaces and to provide environmental protection for said metallic structure. The gel may encapsulate the entire metallic structure so that portions of the metallic structure pierces through the gel when the gasket is installed to make electrical contact. Alternatively portions of the metallic structure may extend beyond the surface of the gel and the gel deforms to cover exposed portions of the metallic structure when the gasket is installed. The gasket of this invention provides moisture seal and is resistant to corrosion.

    摘要： The present invention generally discloses the use of a nanostructured non-silicon thin film (such as an alumina or aluminum thin film) on a supporting substrate which is subsequently coated with an active layer of a material such as silicon or tungsten. The base, underlying non-silicon material generates enhanced surface area while the active layer assists in incorporating and transferring energy to one or more analytes adsorbed on the active layer when irradiated with a laser during laser desorption of the analyte(s). The present invention provides substrate surfaces that can be produced by relatively straightforward and inexpensive manufacturing processes and which can be used for a variety of applications such as mass spectrometry, hydrophobic or hydrophilic coatings, medical device applications, electronics, catalysis, protection, data storage, optics, and sensors.

    摘要： The present invention provides methods of electrophoretically separating macromolecular species, as well as compositions and systems useful in carrying out such methods. Specifically, the methods of the present invention comprise providing a substrate that has at least a first capillary channel disposed therein. The surface of the channel has a first surface charge associated therewith, and is filled with a water soluble surface adsorbing polymer solution that bears a net charge that is the same as the charge on the capillary surface.
