TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organic material comprises polymer. The tritiated material comprises tritiated polymer. The polymer comprises trimethylsilylacetylene poly(vinyl acetylene) (TMS PVacet) (104). The tritium in the tritiated material is present at greater than or equal to 20 wt.%. The organic material is unsaturated. The organic material has carbon-carbon (C-C) triple or double bond(s). The tritiated material is saturated. The ratio of tritium atoms to carbon atoms in tritiated material is greater than or equal to 1.25:1, preferably greater than or equal to 2:1. The organic material comprises tritium atoms. An opening of pore has diameter of 1 nm-500 mu m. Preferred Methods: When organic material is unsaturated, the tritiating of organic material preferably comprises addition, particularly catalytic tritium addition. When organic material has C-C triple bond(s), the tritiating of organic material comprises addition of the tritium in the form of tritium gas to C-C triple bond. When organic material has C-C double bond, the tritiating of organic material comprises addition of tritium in the form of tritium gas to the C-C double bond. The tritiating of organic material comprises tritium oxide hydrolysis and further tritiates organic material. The tritiating of organic material comprises addition and substitution. The method includes synthesizing polymer particularly TMS PVacet by reacting vinyl bromide with TMS acetylene. The vinyl bromide is tritiated before the synthesizing polymer. The method can also comprise reacting vinyl bromide with TMS acetylene in the presence of catalyst to form TMS-protected vinyl acetylene, polymerizing the TMS protected vinyl acetylene to generate TMS PV acet, hydrolyzing the TMS PV acet with tritiated water to form PVacet-T, and adding tritium to PVacet-T (205) to yield tritiated poly(1-ethylethylene) (201). The wetting comprises forming layer of 30-50 nm on walls of pore(s) in porous semiconductor.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The tritiated polymer is tritiated poly(1-ethyl ethylene) ((C4H3T5)n). EXAMPLE - No suitable example given.
