Patent number: 8575548Abstract: A transport of plasmonic particles through a mineral formation is analyzed by flowing a plasmonic particles solution through an immobile phase (e.g., a mineral formation), determining an absorbance of the plasmonic particles solution subsequent to flowing the plasmonic particles solution through the immobile phase, comparing the determined absorbance of the plasmonic particles solution with an absorbance of the plasmonic particles solution determined previous to flowing the plasmonic particles solution through the immobile phase, and determining an absorbance of the plasmonic particles to the immobile phase as a function of the comparison.

Patent number: 8562935Abstract: The present invention is directed towards methods (processes) of providing large quantities of carbon nanotubes (CNTs) of defined diameter and chirality (i.e., precise populations). In such processes, CNT seeds of a pre-selected diameter and chirality are grown to many (e.g., hundreds) times their original length. This is optionally followed by cycling some of the newly grown material back as seed material for regrowth. Thus, the present invention provides for the large-scale production of precise populations of CNTs, the precise composition of such populations capable of being optimized for a particular application (e.g., hydrogen storage). The present invention is also directed to complexes of CNTs and transition metal catalyst precurors, such complexes typically being formed en route to forming CNT seeds.Type: GrantFiled: October 14, 2004Date of Patent: October 22, 2013Assignee: William Marsh Rice UniversityInventors: Robert H.

Patent number: 8566053Abstract: A method for estimating and tracking locally oscillating signals. The method comprises the steps of taking measurements of an input signal that approximately preserve the inner products among signals in a class of signals of interest and computing an estimate of parameters of the input signal from its inner products with other signals. The step of taking measurements may be linear and approximately preserve inner products, or may be non-linear and approximately preserves inner products. Further, the step of taking measurements is nonadaptive and may comprise compressive sensing. In turn, the compressive sensing may comprise projection using one of a random matrix, a pseudorandom matrix, a sparse matrix and a code matrix. The step of tracking said signal of interest with a phase-locked loop may comprise, for example, operating on compressively sampled data or by operating on compressively sampled frequency modulated data, tracking phase and frequency.Type: GrantFiled: March 19, 2010Date of Patent: October 22, 2013Assignee: William Marsh Rice UniversityInventors: Richard G.
