Abstract: The present invention is an apparatus and method of using the apparatus for separating individual particles from a collection of clumps (or bundles or aggregates) of particles. The apparatus has n number of separation columns, wherein each separation column is connected at an upper portion thereof to at least one fluid connection, and a particle collector. A pressurized fluid flows through the apparatus and 1) suspends a portion of the clumps within the separation column and/or the at least one fluid connection thereby separating at least some clumps into smaller clumps and/or individual particles; and 2) conveys a portion of the clumps and/or individual particles to the next separation column in the series of separation columns, or, in the case of the nth separation column conveys individual particles to the particle collector.

Abstract: A composition of matter including two optionally substituted phenol or optionally substituted aniline units separated by a furan spacer has been prepared. In particular, the chemical structure has a novolac bridge between the central furan ring and the two attached optionally substituted phenol and/or optionally substituted aniline units. These compounds can be modified to be used in various polymer resins. This new structure reduces toxicity relative to BPA/F, makes use of renewable chemicals, and produces certain beneficial polymer properties.
