Filed:

Aug 15, 2002

Appl. No.:

10/219684

Inventors:

Touradj Solouki - Orono ME
Alireza Fattahi - Minneapolis MN

Assignee:

University of Maine System Board of Trustees - Bangor ME

International Classification:

G01N 3100

US Classification:

702 27, 436102

Abstract:

A systematic treatment of chemical equilibria is used to determine the average molecular weight of the Suwannee River fulvic acids directly from aqueous solutions. Additionally, parameters such as equilibrium constant and reaction stoichiometry can be calculated. The measurement of the initial mass of unknown analytes is not needed for the determination.

Abstract:

The disclosure provides a system and a method for reducing hazardous gases, including PHGs, through one or more photocatalysts in a filter system. A microstructure of the photocatalytic filter can be formed using biological systems as a template for the photocatalysts to be deposited thereon. The biological system can be removed by heat, oxidation, or by chemical processes to leave the photocatalytic template as a filter for the gases. In various embodiments, multiple photocatalysts can be activated at different wavelengths to filter different gases, or multiple photocatalysts can be activated at the same wavelength to filter different gases, or a photocatalyst can be activated at different wavelengths to filter different gases, or some combination thereof. The activation can be sequential or concurrent. For multiple layers of photocatalysts, the sequence of the photocatalysts can be arranged to reduce damaging output from an upstream photocatalyst to one or more downstream photocatalysts.

Abstract:

The present disclosure provides a system and method for mass spectrometry imaging in a multi-stage ionization applying different technologies by decoupling the desorption and ionization events. At a first stage, a primary beam, such as an ion beam, desorbs one or more molecules of a targeted sample, and at a second stage the desorbed molecules are ionized. The system and method can act independent of a matrix application to the target sample for a direct analysis and has the spatial resolution needed to operate in nano-meters resolution for a cell-by-cell analysis, if desired. The first stage desorption applies a first technique that allows neutral molecules of the target sample to become desorbed from the surface without requiring the molecules to be ionized during the desorption. The second stage ionizes the neutral molecules after the desorption in the first stage, when the defined target molecules have been volatilized.
