Patent number: 9878272Abstract: A method is provided for making a porous inorganic membrane by using a mixture of an inorganic material, organic polymer particles and a solvent to form a slurry, the particles being non-spherical, distributing the slurry onto a surface, drying the slurry to remove the solvent and firing the dried slurry to produce the porous inorganic membrane. Examples of organic polymer particles include particles of acrylic. A substrate with a porous inorganic membrane disposed on the substrate is also provided, the inorganic membrane having an average thickness of from about 0.5 micron to about 30 microns, a porosity of from about 30% to about 65%, a median pore size (d50) of from about 0.01 micron to about 1 micron, and a value of (d90?d10)/d50 less than about 2, as measured by mercury porosimetry. An example of a substrate includes an inorganic porous support.Type: GrantFiled: May 25, 2011Date of Patent: January 30, 2018Assignee: Corning IncorporatedInventors: Dana Craig Bookbinder, Gary S Calabrese, Yunfeng Gu, Jianguo Wang

Patent number: 5510216Abstract: The invention is directed to a process for patterning a substrate in a selective pattern. In one embodiment, the process comprises the steps of forming a patterned coating over a substrate surface whereby portions of the substrate are covered by the patterned coating and portions of the substrate remain uncoated. A layer of a ligating material is coated over at least those portions of the substrate free of the patterned coating. The ligating layer is one that is capable of ligating with an electroless metal plating catalyst. The article so formed is then contacted with an electroless metallization catalyst and then with an electroless plating solution to form a patterned metal deposit on the substrate.Type: GrantFiled: August 29, 1995Date of Patent: April 23, 1996Assignee: Shipley Company Inc.Inventors: Gary S. Calabrese, Jeffrey M. Calvert, Mu-San Chen, Walter J. Dressick, Charles S. Dulcey, Jacque H. Georger, Jr., John F. Bohland, Jr.

Patent number: 5500315Abstract: Methods and compositions for electroless metallization. In one aspect, the invention is characterized by the use of chemical groups capable of ligating with an electroless metallization catalyst, including use of ligating groups that are chemically bound to the substrate. In a preferred aspect, the invention provides a means for selective metallization without the use of a conventional photoresist patterning sequence, enabling fabrication of high resolution metal patterns in a direct and convenient manner.Type: GrantFiled: October 4, 1994Date of Patent: March 19, 1996Assignee: Rohm & Haas CompanyInventors: Jeffrey M.

Patent number: 5070023Abstract: Aqueous acidic ferrioxalate compositions are disclosed for use as calibrants of pCO2 and of PO2 after photodecomposition. Compositions with high iron(III) to oxalate molar ratios (e.g., 5:1 to 100:1 with 0.3 to 15 millimolar oxalate) produce carbon dioxide on exposure without oxygen consumption. Compositions with low iron(III) to oxalate ratios (e.g., 1:100 to 1:2000) with 0.1 to 5 millimolar iron(III) produce carbon dioxide on exposure with concurrent oxygen consumption. Use of the two types of compositions enables calibration values to be established with varying pCO2 values and with, respectively, high and low pO2 values.Type: GrantFiled: February 3, 1989Date of Patent: December 3, 1991Assignee: Fisher Scientific CompanyInventor: Gary S. Calabrese

Patent number: 5061631Abstract: Electrodes for the measurement of pCO2 and/or pO2 are calibrated with an exposed aliquot of a calibration liquid. A constituent such as a ferrioxalate salt in the calibration liquid is converted to the gas in a reproducible concentration by exposure of the aliquot to light. In some instances, the calibration liquid is equilibrated with air prior to exposure. Some mechanisms of light generation of carbon dioxide also consume oxygen, so as to depress the pO2 value by a reproducible amount. The use of two different calibration liquids enables both one-point and two-point calibration of the Clark oxygen electrode and the Severinghaus pCO2 electrode of a blood gas instrument.Type: GrantFiled: October 14, 1988Date of Patent: October 29, 1991Assignee: Fisher Scientific CompanyInventor: Gary S.

Patent number: 4576756Abstract: Methods, materials and apparatus for production of hydrogen peroxide are disclosed. In one preferred embodiment, high surface area circulating elements derivatized with a quinone catalyst are reduced in an electrolytic cell where the cathode may also be derivatized with a quinone catalyst and a solution quinone at low concentration is used as a mediator. Once reduced, the circulating elements are separated and used to form hydrogen peroxide from molecular oxygen in an aqueous, electrolyte-free, environment. The circulating elements can be cycled repeatedly. Particular, novel naphthoquinone compounds are also disclosed.Type: GrantFiled: November 5, 1984Date of Patent: March 18, 1986Assignee: Massachusetts Institute of TechnologyInventors: Mark S.
