"Micronized creatine" commonly refers to creatine monohydrate powder that has undergone a "micronization" process to reduce its particle size. The resulting "micronized creatine monohydrate" powder has an ultra-fine consistency, with each particle being about 20 times smaller than those found in standard creatine monohydrate powder.

• Coal reburning was successfully demonstrated on both a T-fired (Milliken) and a cyclone (Kodak) boiler. On the T-fired boiler, existing mills were used to produce near micronized coal (70 to 72 percent through 325 mesh). On the cyclone boiler, a MicroMill™ was used to produce micronized coal (80 percent or greater through 325 mesh).
