A composite useful for structural components comprised of recycled high density polyethylene and herbaceous fibrous materials and a method to produce composites based on recycled high density polyethylene and chopped herbaceous fibers. An alternative structural composite is disclosed which is comprised of recycled low density polyethylene and chopped herbaceous fibrous material.

Structural materials from recycled high density polyethylene and

This invention relates to cisplatin type fluorescently labeled compounds. In particular, the compounds are bis (5-aminofluorescein)-dichloroplatinum (II) or certain substituted analogues thereof. The compounds are useful as radiation sensitivity enhancers and as fluorescent biological tracers. The invention also relates to a unique, single step synthesis for preparing said compounds.

Low toxicity radiation sensitizer

Bis(5-aminofluorescein)dichloroplatinum(II), and substituted fluoresceinamine derivatives of this compound are disclosed as highly effective radiation sensitizers which enhance the effect of ionizing radiation on tumor cells, but uniquely do so without the usual accompanying high toxicity level to surrounding normal cells. A direct combination, single step reaction synthesis is disclosed for preparing bis(5-aminofluorescein)dichloroplatinum(II) from the reaction between an alkali metal tetrachloroplatinate(II) and 5-aminofluorescein.
