Publication number: 20070264185Abstract: The present invention provides systems and methods for quantifying, purifying and separating fullerenes, such as single wall carbon nanotubes (SWNTs). The purification/separation combination provides nearly 100% carbonaceous impurity-free SWNT content from a given impure sample and provides a desired chirality and diameter from a given non-separated sample. Nanometrological validation of the success of purification and separation uses a pyroelectric detector and Raman spectroscopy in a single system, thus providing a critical aspect for the nanomanufacturing environment. The purification/separation and nanometrological validations may be performed in a feedback loop to provide a satisfactorily refined sample and optimized purification/separation settings.Type: ApplicationFiled: May 8, 2007Publication date: November 15, 2007Applicant: ADA TechnologiesInventors: Thomas Campbell, Kent Henry

Patent number: 7288499Abstract: A regenerable, high-capacity sorbent for removal of mercury from flue gas and processes and systems for making and using the sorbent. A phyllosilicate substrate, for example vermiculite or montmorillinite, acts as an inexpensive support to a thin layer for a polyvalent metal sulfide, ensuring that more of the metal sulfide is engaged in the sorption process. The sorbent is prepared by ion exchange between the silicate substrate material and a solution containing one or more of a group of polyvalent metals including tin (both Sn(II) and Sn(IV)), iron (both Fe(II) and Fe(III)), titanium, manganese, zirconium and molybdenum, dissolved as salts, to produce an exchanged substrate. Controlled reaction of a sulfide ion source with the one or more polyvalent metals that are exchanged on the silicate substrate produces the sorbent. The sorbent is used to absorb elemental mercury or oxidized mercury species such as mercuric chloride from flue gas containing acid gases (e.g.Type: GrantFiled: February 19, 2004Date of Patent: October 30, 2007Assignee: ADA Technologies, IncInventors: John S Lovell, Craig S Turchi, Thomas E Broderick
