		<description><![CDATA[A process for forming hollow glass micro-spheres with walls of controllably variable thickness in a size range of 50 to 5,000 microns, embodying (1) preparation of a water slurry of finely particulated, high temperature and low temperature glass formers; (2) prilling the slurry in a vertical spray drying tower; (3) separating and supporting the individual prilled feed material; (4) heating the feed material to glassification of the high temperature glass former while maintaining appropriate geometry and shell thickness and (5) cooling the finished product. The high temperature glass former is preferably a naturally occurring soda feldspar. The process is particularly adapted to form thicker walled micro-spheres of larger size and high quality.]]></description>

		<description><![CDATA[One embodiment disclosed herein includes a method of treating one or more symptoms of irritable bowel syndrome by  administering to the subject adsorbent carbon microspheres with a particle size of 0.01mm to about 2 mm  to reduce the abdominal discomfort or pain. In one embodiment, the amount of the adsorbent carbon microspheres is sufficient to achieve at least about a 50% reduction in the number of days the subject experiences abdominal pain or discomfort.]]></description>

		<description><![CDATA[Polymer microspheres offer an excellent solution to creating precise pore sizes in ceramics at reasonable prices.  Polyethylene microspheres offer the added benefit of minimal residue after firing, and the availability in wide size ranges from a few micron up to 1000um (1mm).    Highly spherical microspheres have the added benefit of creating strong pores without any stress risers that might cause fracturing of the parent ceramic.]]></description>

		<description><![CDATA[Spray drying has been used in the production of fine powders from emulsions for many years, but it is not a process in which most people associate the production of microspheres.  This journal article shows how the authors were able to produce highly spherical microspheres in the 1-10um range by controlling the levels of Chitosan and crosslinking agents used.]]></description>
