WIPO Publishes Three Patents Involving Ohio University Chemists

The World Intellectual Property Organization published three patents involving Ohio University Chemistry & Biochemistry faculty.

‘Online Monitoring of Fuel Cell Reactions by Desorption Electrospray Mass Spectrometry’

WIPO published a patent of Ohio University for “Online Monitoring of Fuel Cell Reactions by Desorption Electrospray Mass Spectrometry.”

International Patent Application Number PCT/US2013/068922

International Patent Application Number PCT/US2013/068922

Publication No. WO/2014/074699 was published on May 15.

The inventors are Dr. Hao Chen, Associate Professor of Chemistry & Biochemistry; Ning Pan; and Dr. Howard D. Dewald, Professor of Chemistry & Biochemistry and Associate Provost for Faculty & Academic Planning at Ohio University.

Abstract: “A mass spectrometry-based method of directly online detecting fuel cell reaction products includes passing a reactant sample (16) through a fuel cell (12) to form reaction products that exit the fuel cell (12) in an output stream (26). The method also includes adding a derivatizing reagent (32) to the output stream (28) to form a derivatized output stream (34), wherein the derivatizing reagent (32) reacts with a potential reaction product to thereby form a derivatized reaction product if the potential reaction product is present. The method further includes directing a charged solvent (44) toward the derivatized output stream (34) to thereby ionize the derivatized output stream (34) and directing the ionized, derivatized output stream (54) to a mass spectrometer (14), the mass spectrometer (14) being configured to detect the derivatized reaction product.”

The patent was filed on Nov. 7, 2013 under Application No. PCT/US2013/068922.

‘Ionization of Chemicals in Mixture at Low PH by Ambient Ionization/Mass Spectrometry’

The WIPO published a patent of “Ohio University for Ionization of Chemicals in Mixture at Low PH by Ambient Ionization/Mass Spectrometry.”

Publication No. WO/2014/074701 was published on May 15.

The inventors are Dr. Hao Chen, Associate Professor of Chemistry & Biochemistry; Ning Pan, and Pengyuan Liu.

Abstract: “A mass spectrometry-based method for analyzing an acidic organic target compound includes directing a charged solvent (44) toward a pre-acidified sample (12) comprising the target compound, to thereby ionize the pre-acidified sample (12). The method further includes directing the ionized pre-acidified sample (54) to a mass spectrometer (18), the mass spectrometer (18) being configured to identify and quantify the target compound.”

The patent was filed on Nov. 7, 2013 under Application No. PCT/US2013/068925.

‘Method for Identifying Layers Providing Corrosion Protection in Crude Oil Fractions’

WIPO published a patent of ExxonMobil, Research and Engineering Co., and Ohio University for “Method for Identifying Layers Providing Corrosion Protection in Crude Oil Fractions.”

A news release reported Publication No. WO/2014/074435 was published on May 15.

The inventors are: Henry Alan Wolf (US), Fang Cao (US), Saul C. Blum (US), Alan M. Schilowitz (US), Shiun Ling (US), James Mclaughlin (US), Srdjan Nesic (US), Peng Jin (US) and Gheorghe Bota (US).

Abstract: “A method for determining and identifying corrosion protective layers that provide corrosion protection against crude oils and crude oil fractions is disclosed. The method identifies naturally occurring constituents in crude oils that indirectly provide corrosion protection. A method assessing the potential of these constituents is also disclosed. The method includes exposing metal coupons with the crude oil or crude fraction of interest at the expected operating temperature of concern. The corrosion potential assessment further analyzes the exposed coupons with transmission electron microscopy and an additional high temperature exposure that challenges the tenacity of the protection offered by the corrosion protective layer.”

The patent was filed on Nov. 4, 2013 under Application No. PCT/US2013/068234. For more information, visit: http://www.wipo.int/patentscope/search/en/detail.jsf?docId=WO2014074435.
