Patent number: 10121607Abstract: A separator such as for an electrochemical double layer capacitor includes acicular inorganic particles that are dried to form a porous membrane. Example inorganic particles are calcium silicate particles. A deposition method implementing slurry that includes the acicular inorganic particles and a dispersing medium along with a binder material can be used to form the separator layer directly on electrode materials.Type: GrantFiled: January 28, 2014Date of Patent: November 6, 2018Assignee: Corning IncorporatedInventors: Felipe Miguel Joos, Satyanarayana Kodali, Atul Kumar, Charles Warren Lander, Kamjula Pattabhirami Reddy, Huthavahana Kuchibhotla Sarma

Patent number: 9651720Abstract: A glass article including: at least one anti-glare surface having haze, distinctness-of-image, surface roughness, and uniformity properties, as defined herein. A method of making the glass article includes, for example: depositing deformable particles on at least a portion of a glass surface of the article; causing the deposited deformable particles on the surface to deform and adhere to the surface; and contacting the surface having the adhered particles with an etchant to form the anti-glare surface. A display system that incorporates the glass article, as defined herein, is also disclosed.Type: GrantFiled: March 26, 2015Date of Patent: May 16, 2017Assignee: Corning IncorporatedInventors: Charles Warren Lander, Timothy Edward Myers, Kelvin Nguyen, Alan Thomas Stephens, II

Publication number: 20160355689Abstract: A glass article including: at least one anti-glare surface having haze, distinctness-of-image, surface roughness, uniformity properties and sparkle properties, as defined herein. A method of making the glass article includes, for example, slot coating a suspension of particles on at least one surface of the article to provide a particulated mask covering from about 40 to 92% of the coated surface area; contacting the at least one surface of the article having the particulated mask and an etchant to form the anti-glare surface, and optionally continuously polishing the suspension of particles just prior to slot coating. A display system that incorporates the glass article, as defined herein, is also disclosed.Type: ApplicationFiled: August 22, 2016Publication date: December 8, 2016Inventors: Charles Warren Lander, Kelvin Nguyen, Alan Thomas Stephens, II

Patent number: 8871116Abstract: Water-based conductive ink compositions may include acid-washed graphite particles, carbon black particles, at least one polymeric dispersant, at least one acrylic binder, at least one polyvinylpyrrolidone binder, at least one defoamer, and an aqueous carrier. At least 90 wt. % of the acid-washed graphite particles and the carbon black particles, based on the combined weight of the acid-washed graphite particles and the carbon black particles, may have particle sizes less than 10 ?m. The water-based conductive ink composition may have a total elemental contaminant level of less than 100 ppm, based on the total weight of the water-based conductive ink composition. Methods for preparing the water-based conductive ink compositions may include preparing a letdown phase from a first premix containing carbon black and a second premix containing acid-washed graphite. The methods may include washing graphite particles in an strong acid such as hydrochloric acid, nitric acid, sulfuric acid, or mixtures thereof.Type: GrantFiled: September 30, 2011Date of Patent: October 28, 2014Assignee: Corning IncorporatedInventors: Renee Kelly Duncan, Kishor Purushottam Gadkaree, Felipe Miguel Joos, Charles Warren Lander
