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.

Abstract: Phase change (hot melt) ink compositions for use in a phase change (hot melt) ink jet recording device in which recording is conducted by thermally melting the ink at a temperature above ambient temperature (20° C.) to provide prints that possess high quality images, scratch resistance, abrasion resistance, low-temperature storage stability and flexibility, offset and pick resistance, adhesion, and other desired properties are disclosed to comprise: (a) from about 0.1% to about 30% of one or more colorants; and (b) from about 0.1 to about 99.9% of one or more hybrid polymers. Components other than those listed above may be included in the ink compositions to achieve specific printer, substrate, or end use requirements.

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.

Abstract: A cationic, water-soluble polymer is disclosed as a substrate treatment resin (i.e., coating) to improve color-fastness and adhesion of an ink-jet ink printed onto the substrate. More particularly, a 50% solids aqueous solution of a cationic acrylic resin is provided as the printed substrate treatment resin. Also disclosed is a method for preparing the invention resin.
