US Patent:

20080014654, Jan 17, 2008

Filed:

Nov 16, 2005

Appl. No.:

11/281784

Inventors:

R. Weisman - Houston TX, US
Sergei Bachilo - Houston TX, US
John-David Rocha - Missouri City TX, US
John Casey - Houston TX, US

Assignee:

William Marsh Rice University - Houston TX

International Classification:

G01N 21/64

US Classification:

436172000, 436171000, 422082080

Abstract:

The present invention is directed toward methods and devices for analyzing populations of single-wall carbon nanotubes (SWNTs) on the basis of their fluorescence properties and the comparison of said properties to fluorescence profiles of pre-determined SWNT compositions. Generally, such analyzing yields information about the composition of the SWNTs within said population. Such information includes, for example, the relative abundances of semiconducting SWNTs, the diameter distribution of such SWNTs, and the relative abundances of one or more particular SWNT species—as identified by one or more specific nanotube indices (n,m). The methods and devices of the present invention provide for the analysis of SWNT compositions in a rapid and efficient manner.

Abstract:

An improved zinc anode for use in a high density rechargeable alkaline battery is disclosed. A process for making the zinc electrode comprises electrolytic loading of the zinc active material from a slightly acidic zinc nitrate solution into a substrate of nickel, copper or silver. The substrate comprises a sintered plaque having very fine pores, a high surface area, and 80-85 percent total initial porosity. The residual porosity after zinc loading is approximately 25-30%. The electrode of the present invention exhibits reduced zinc mobility, shape change and distortion, and demonstrates reduced dendrite buildup during cycling of the battery. The disclosed battery is useful for applications requiring high energy density and multiple charge capability.
