A novel proton conducting polymer membrane which contains a network of voids within the membrane is disclosed. The overwhelming amount of data in a multidimensional database that may be viewed by a user, such as a data analyst, is reduced to the selected and associated data by use of index data and related index data, according to the present invention. The embedded pattern is comprised of a solvent insoluble material such that attempted delamination of the document using solvents results in visually detectable tampering. In one embodiment, the quantum dots are formed in quantum wells for improved carrier confinement. The resulting hydrocarbon-lean production water has a sufficiently low hydrocarbon content that it is eligible for more intensive processing, such as with organophillic clay cartridges. A chamber of the device is hermetically sealable with respect to ambient atmosphere and is defined by an interior of the second portion, andor a space formed between the first and second portions.
