  • Patent number: 6696384
    Abstract: A new shaped activated carbon and the method of its manufacture are disclosed. The invention resides in the crosslinking of a polymeric cellulose, such as sodium carboxymethylcellulose (CMC), within the carbon bodies after they are shaped, employing the CMC as a binder for the activated carbon. The approach to attain product mechanical strength and water stability by crosslinking rather than high temperature heat treatment is not obvious from the prior art teaching. The crosslinking reaction occurs at temperatures below 270° C. In addition, this new binder technology produces shaped carbon bodies having key properties beyond the best level that has been accomplished with other binders.

  • Patent number: 6682931
    Abstract: This invention relates to a method for improving the growth and regeneration potential of embryogenic cell and tissue cultures of coniferous plants retrieved from cryopreservation. In particular, this invention relates to the use of abscisic acid in the post-cryopreservation recovery medium to improve both the growth and somatic embryo production of embryogenic cell and tissue cultures of conifers, thereby enabling more rapid proliferation of the embryogenic cultures and a subsequent increase in the yield of somatic embryos. This method is well-suited for employment with a number of biotechnological uses of embryogenic cultures of coniferous plants retrieved from cryopreservation, including use with embryogenic cultures of coniferous plants and with genetically transformed embryogenic cultures of coniferous plants for producing clonal planting stock useful for reforestation.
