Provided herein is a biological detection system and method of use wherein the biological detection system comprises at least one mixer or liquid bridge for combining at least two liquid droplets and an error correction system for detecting whether or not proper mixing or combining of the two component droplets have occurred.

A fluidized bed mixer for combining a first powder with a second powder for manufacturing a magnet and a method of using the fluidized bed mixer for making the magnet. The first powder material is an alloy powder containing neodymium (Nd), iron (Fe), and boron (B), and the second powder material is an alloy powder or elemental metal powder containing one or more of dysprosium (Dy) and terbium (Tb). The fluidized bed mixer includes a fluidized bed portion in an upper portion of a mixing chamber, a cascading baffle system beneath the fluidized bed portion, and combined powder collection area beneath the cascading baffle system. The fluidized bed mixer is configured to homogenously combine a first powder material with a second powder material in such a way that particles of the second powder material adheres to and covers the outer surfaces of the particles of the first powder material.

Carbonation apparatus is provided for carbonating a mixed input flow of pressurized and refrigerated carbon dioxide and water. A first cartridge is disposed within the carbonation chamber, defining a porous micromesh net in fluid communication with the input flow and a central cavity in fluid communication with the carbonation chamber output port. The micromesh net is configured to break up chains of water molecules passing through the net, to enhance bonding between the water and carbon dioxide molecules within the cartridge. The net also responds to the flow of water and carbon dioxide molecules impacting and passing through the net by generating a passive polarizing field that has a polarizing influence on the water molecules to further enhance. Beads may be provided within the cartridge for capturing and stabilizing carbon dioxide molecules to yet further enhance bonding between the water and the carbon dioxide molecules.
