A method, a computer program product, and a system for detecting sensitive information in a non-relational database. The method includes partitioning a non-relational database into a plurality of partitions that are based characteristics relating to the non-relational database. The method also includes analyzing, by proceeding in an iterative manner with a first partition from the plurality of partitions, detecting a plurality of documents within the first partition containing metadata and data values, populating a table with the metadata representing fields and the data values relating to the metadata representing records, detecting sensitive information in the table, and recording the sensitive information. The method further includes proceeding with a second partition acting as a next entry for a next iteration, until all partitions in the plurality of partitions are analyzed, and reporting the sensitive information gathered from the partitions.

A method of preparing catalyst agglomerates for electrochemical devices is provided. The method comprises dispersing particles of a catalyst in a non-aqueous solvent to form a dispersion of the catalyst, adding an ion conducting polymer in a dilute solution to the dispersion of the catalyst under agitation to form catalyst agglomerates, and stirring the dispersion of the catalyst and the catalyst agglomerates to control the growth of the agglomerates. A directly applicable catalyst composition is also provided. The catalyst composition comprises the catalyst agglomerates prepared according to the present invention, a solvent to plasticize surfaces of the catalyst agglomerates and the membrane, and a non-aqueous carrier solvent.
