<title><![CDATA[Nanoelectromechanical digital inverter]]></title>
<link>http://www.freepatentsonline.com/7612270.html</link>
<description><![CDATA[A digital inverter formed by three carbon nanotubes (CNTs) extending vertically from a substrate, one CNT functioning as first source (S 1 ) and having a first logic signal applied to it, another CNT functioning as second source (S 2 ) and having a second logic signal applied to it, a third CNT functioning as gate (G), and disposed between the two sources (S 1 , S 2 ). A drain (D) contact is associated with the gate (G). A logic signal applied to the gate (G) causes one or the other of the sources (S 1 , S 2 ) to deflect, contacting the drain (D) and transferring its logic signal thereto—such as logic “0” on the gate resulting in logic “1” (from one of the sources) being transferred to the drain (D), and logic “1” on the gate resulting in logic “0” (from the other of the sources) being transferred to the drain (D).]]></description>

<title><![CDATA[Triangular nanoframes and method of making same]]></title>
<link>http://www.freepatentsonline.com/7611562.html</link>
<description><![CDATA[The present invention provides nanoprisms etched to generate triangular framework structures. These triangular nanoframes possess no strong surface plasmon bands in the ultraviolet or visible regions of the optical spectrum. By adding a mild reducing agent, metal ions remaining in solution can be reduced, resulting in metal plating and reformation of nanoprisms. The extent of the backfilling process can be controlled, allowing the formation of novel nanoprisms with nanopores. This back-filling process is accompanied by a regeneration of the surface plasmon bands in the UV-visible spectrum.]]></description>
