Publication number: 20230122407Abstract: A small-sized, portable enclosure protects a gas sensor against degradation due to environmental exposure and changes in atmospheric conditions. The protective enclosure includes an inlet for introduction of a gas into the enclosure, an outlet for release of the gas upon completion of a sensing run, and a number of in-line filters that remove from the inflowing gas sample analytes, contaminants, and other materials that can compromise the integrity of the sensor or cause the sensor to degrade over time. The enclosure does not include any filters during the measurement phase of the sensing run in order to allow the gas sensor to accurately measure an unmodified gas mixture and/or analyte.Type: ApplicationFiled: December 15, 2022Publication date: April 20, 2023Inventors: Thomas Geoffrey Pattison, Tom Van der Pol, Linda Karin Sundberg, Krystelle Lionti, Andrea Fasoli, Luisa Dominica Bozano

Publication number: 20220390401Abstract: A method of preparing electronically conductive polyaniline that forms a self-supporting dispersion in water is described. The binder-free dispersion was coated on a pair of interdigitated metal electrodes to form a gas sensing layer of a chemical sensor. The chemical sensor utilizes electrochemical impedance spectroscopy (EIS) to detect and characterize a chemical compound in a gaseous state in contact with the sensing layer. Impedance of the sensing layer is measured over a range of alternating current frequencies. The impedance data allows identification and concentration of the chemical compound to be determined when compared to reference impedance data. The analysis of the impedance measurements is adaptable to machine learning.Type: ApplicationFiled: May 11, 2021Publication date: December 8, 2022Inventors: Tim Erdmann, Angelo Milone, Linda Karin Sundberg, Siddhartha Das, Ronald R.

Patent number: 11221318Abstract: Provided is a system for detection and discrimination of gases, such as volatile organic compounds (VOCs), in a sample comprising two chambers, a first chamber equipped with a crystalline microporous material (CMM) and a second chamber equipped with a gas detector. A gas sample is introduced first into the second chamber for detection by the gas detector and is then re-routed to the first chamber for adsorption/desorption on the CMM. The gas detector in the second chamber produces electronic signals that correspond to the adsorption/desorption profile for the gas, which allows for discrimination of the gas in the sample from other possible gas samples.Type: GrantFiled: July 24, 2019Date of Patent: January 11, 2022Assignee: International Business Machines CorporationInventors: Siddhartha Das, Andrea Fasoli, Luisa Dominica Bozano

Patent number: 8426113Abstract: The present invention provides chemically amplified silsesquioxane polymers for preparing masks using e-beam lithography. The silsesquioxane polymers have reactive sidechains that in the presence of an acid undergo acid catalyzed rearrangement to generate reactive functionalities that crosslink to form Si—O—Si bonds. The reactive side-chains comprise ?- and ?-substituted alkyl groups bound to the silicon of the silsesquioxane polymer. The substituent of the ?- and ?-substituted alkyl group is an electron withdrawing group. Resists generated with the chemically amplified silsesquioxane polymers of the present invention and imaged with e-beams have resolution of ?60 nm line/space.Type: GrantFiled: August 13, 2010Date of Patent: April 23, 2013Assignee: International Business Machines CorporationInventors: Luisa Dominica Bozano, Blake W.

Patent number: 7151029Abstract: A multi-stable memory or data storage element is used in crosspoint data-storage arrays, as a switch, a memory device, or as a logical device. The general structure of the multi-stable element comprises a layered, composite medium that both transports and stores charge disposed between two electrodes. Dispersed within the composite medium are discrete charge storage particles that trap and store charge. The multi-stable element achieves an exemplary bi-stable characteristic, providing a switchable device that has two or more stable states reliably created by the application of a voltage to the device. The voltages applied to achieve the “on” state, the “off” state, any intermediate state, and to read the state of the multi-stable element are all of the same polarity.Type: GrantFiled: June 14, 2005Date of Patent: December 19, 2006Assignee: International Business Machines CorporationInventors: Luisa Dominica Bozano, Kenneth Raymond Carter, John Campbell Scott

The multi-stable element is stable, cyclable, and reproducible in both the “on” state and the “off” state. The storage medium has a relatively high resistance in both its on and off states.Type: GrantFiled: August 20, 2003Date of Patent: January 17, 2006Assignee: International Business Machines CorporationInventors: Luisa Dominica Bozano, Kenneth Raymond Carter, John Campbell Scott
