Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations

 Appl.No 12735980 Applicant Michel Meyer Inventor Michel Meyer

The present invention relates to a material notably adapted for the extraction of metal cations in an aqueous medium, comprising a solid support on which are attached polyazacycloalkane compounds having a ring including at least 4 nitrogen atoms, and wherein the nitrogen atoms of the ring are substituted with coordinating groups, which each are independently:

    • a coordinating group of formula:
      —(CH2)n—C(═O)—NR1R2
    •  or else
    • a both coordinating and binding group, fitting the formula:
      —(CH2)p—C(═O)—NR3-(A)-[support].

      The invention also relates to methods for preparing the aforementioned materials and to different uses thereof, notably for the extraction of Pb2+ cations in an aqueous medium.

 Appl.No 08761933 Applicant COMMISSARIAT ENERGIE ATOMIQUE Inventor RASCALOU FREDERIC
Material (I) comprises a polyazacycloalkane (II) grafted on polypropylene fibers. An independent claim is included for a preparation of the material constituted by a polyazacycloalkane grafted on the polypropylene fibers, comprising radical polymerization of a polyazacycloalkane monomer carrying a radical polymerizable group, in the presence of polypropylene fibers carrying peroxide and/or hydroperoxide functions, followed by a functionalization of free amino polyazacycloalkane functions and/or a saponification and hydrolysis of ester functions carried by the polyazacycloalkane.
