Publication number: 20230078098Abstract: A pre-loaded cleaning substrate, and related systems and methods for picking up particles with an aspect ratio (L/D) greater than 300 (e.g., hair), or greater than 1200 (e.g., particularly long hairs). The substrate (e.g., a nonwoven) may include only a single layer of material. The pre-loaded substrate is loaded (e.g., during manufacture) with a cleaning composition. The fibers of the substrate may have an average diameter less than 15 ?m, the substrate may have an air permeability of 35 ft3/min to 75 ft3/min, and the liquid cleaning composition may have a surface tension of less than about 50 dynes/cm. Together, the combination of the particular substrate and cleaning composition may facilitate markedly improved ability to pick up high L/D aspect ratio particle debris (e.g., such as hair), while retaining such particles (e.g., providing hair retention index values of at least 20).Type: ApplicationFiled: November 15, 2022Publication date: March 16, 2023Inventors: Ashish K. Jha, Nikhil P. Dani, David R. Scheuing, Nancy A. Falk, Bryan K. Parrish

Publication number: 20180192681Abstract: Packaged food compositions including but not limited to emulsified salad dressings (e.g., an oil/water emulsion) that contain calcium carbonate and phosphoric acid. Under conditions present in the salad dressing, the calcium carbonate reacts with the phosphoric acid to form surface modified calcium carbonate particles that dissolve over the shelf-life of the salad dressing to slowly release CO2 into the emulsion, resulting in a whipped, bodied texture for the salad dressing within the bottle or other container.Type: ApplicationFiled: December 15, 2017Publication date: July 12, 2018Inventors: Maria G.

Patent number: 8900940Abstract: In general, aspects of the present invention relate to approaches for forming a semiconductor device such as a FET with reduced gate stack height variance. Specifically, when a gate stack height variance is detected/identified between a set of gate stacks, a hard mask layer and sets of spacers are removed from the uneven gate stacks leaving behind (among other things) a set of dummy gates. A liner layer and an inter-layer dielectric are formed over the set of dummy gates. The liner layer is then removed from a top surface (or at least a portion thereof) of the set of dummy gates, and the set of dummy gates are then removed. The result is a set of gate regions having less height variance/disparity.Type: GrantFiled: January 10, 2013Date of Patent: December 2, 2014Assignee: GLOBALFOUNDRIES Inc.Inventors: Ashish K.

Patent number: 8440765Abstract: The present invention relates to copolymer compositions for alcohol-selective membranes and methods of selectively separating an alcohol such as ethanol from an aqueous solution using such membranes. The copolymer compositions may be block copolymers of polystyrene-polybutadiene-polystyrene (hereafter “SBS”) having cylindrical morphologies; graft diblock copolymers synthesized by ring-opening metathesis polymerization of two cycloalkene monomers, wherein at least one of the cycloalkene monomers is substituted with one or more polydialkylsiloxane groups; or triblock copolymers comprising a middle block comprising a polymerized cycloalkene monomer and two end groups. The synthesized graft and triblock copolymer compositions may have a spherical, lamellar, cylindrical, double diamond, or gyroid morphologies. The copolymer compositions may contain a structural block that imparts essential mechanical properties to the membrane (e.g., polystyrene) and may also contain an alcohol transporting block (e.g.Type: GrantFiled: March 10, 2011Date of Patent: May 14, 2013Assignee: The Regents of the University of CaliforniaInventors: Nitash P.
