Abstract:
The present invention relates to sample presentation devices useful in performing analytical measurements. These devices have been configured to enable various aspects of liquid handling such as: retention, storage, transport, concentration, positioning, and transfer. Additionally, these devices can enhance the detection and characterization of analytes. The sample presentation devices of the present invention are comprised of one or more substrates having a plurality of zones of differing wettability. Methods of analyzing samples using the sample presentation device of the invention, as well as methods of making the sample presentation devices are disclosed.
Abstract:
An offshore submarine storage facility for highly chilled liquified gas, such as liquified natural gas, is disclosed. The facility includes an elongated, vertically oriented submerged frame. An insulated storage tank is movably mounted to the frame so as to be positionable at various depths in the water. The tank is constructed to transfer external ambient water pressure to the liquified gas without intermixture. This transferred pressure aids in maintaining the liquified state of the stored liquified gas.
