NanoGram, Franklin Fuel Cells, and Intelliburn announce raises

• Speaking of nanotechnology, nanotech process innovator NanoGram announced an $18.7M round of financing, led by Technology Partners, and including existing investors ATA Ventures, Nth Power Technologies, Bay Partners, Harris & Harris Group, Rockport Capital Partners, Institutional Venture Partners and SBV Venture Partners. Harris & Harris also put out a separate PR describing their portion of the raise.
