US Patent 7814776 - CNT-Quartz resonator

http://www.freepatentsonline.com/7814776.html

This patent teaches a way to measure mass with a resolution of femtograms (1 femtogram = 1 millionth of a nanogram) using a nanotube coated micromachined quartz crystal. Claim 1 reads:

1. A method for increasing the quality factor of at least one sensor comprising:

adding a layer of nanotubes to the at least one sensor to thereby increase the quality factor of the at least one sensor and form a nanotube-coated device;

placing the nanotube-coated device in a vacuum chamber for a period of time sufficient to further increase the quality factor of the at least one sensor.

US Patent 7432039 - Combined molecular and non-molecular lithography

http://www.freepatentsonline.com/7432039.html

Photoresists are commonly used in semiconductor processing to define patterns for doping, etching, and other microfabrication steps. This patent from the Penn State Research Foundation
teaches combining the patterning of resists with molecular film patterning to define nanoscale structures. Claim 1 reads:

1. A method of fabricating a pattern on a surface of a substrate, said pattern comprising a plurality of features, the method comprising:

applying at least one non-molecular lithographic technique with at least one molecular lithographic technique to simultaneously define a size and shape of at least one of the features of the pattern;

wherein the applying the at least one non-molecular lithographic technique with the at least one molecular lithographic technique includes removing both a resist used in the lithographic technique and at least one molecular layers used in the at least one molecular lithographic technique to simultaneously define the size and the shape of the at least one of the features of the pattern.

US Patent 7341774 - High efficiency electronics/optoelectronics using nanostructured porous material

http://www.freepatentsonline.com/7341774.html

The large surface-to-volume provided by nanostructured materials allows for a high degree of electric charge accumulation which can be very valuable in applications such as supercapacitors and photovoltaics. This patent from Penn State Research (which may have priority going as far back as 2000) includes some basic claims to nanostructured porous material useful to such applications. Claim 1 reads:

1. An electronic or opto-electronic device comprising: a first conductive layer electrode; a nanostructured porous material disposed on said first conductive layer electrode such that said nanostructured porous material is in substantial electrical connectivity with said first conductive layer electrode; an organic or inorganic material substantially embedded into at least one void of said nanostructured porous material such that an interface is substantially formed between said nanostructured porous material and said embedded material; and a second conductive layer electrode in substantial contact with said embedded material, wherein charge separation, charge injection or charge storage occurs at or near said interface.

I'm not entirely sure what the novel feature of the claims are though. The PTO gave a double patenting rejection which was overcome by a terminal disclaimer but there may be prior art such as this article published in 1998 which seems very similar to the claimed subject matter.
