摘要： A method of preserving, controlling an odor, and/or enhancing and/or mediating antimicrobial activity of a substrate is described, the method comprising administering a surface-reacted calcium carbonate. The surface-reacted calcium carbonate is obtained by a process comprising treating a calcium carbonate-comprising material with at least one H3O+ ion donor, carbon dioxide, and at least one water-soluble metal cation source in an aqueous medium to form an aqueous suspension of surface-reacted calcium carbonate.

摘要： Composition of precipitated calcium carbonate and method of producing the same and the uses of the composition. The composition comprises a plurality of essentially spherical granules having an average diameter of 1-50 um formed from primary precipitated calcium carbonate particles having an average diameter of 30 to 60 nm, capable of liberating at least a part of the primary particles by deagglomeration in aqueous suspension. The present compositions can be used for modifying binders of paints, printing inks, plastics, adhesives, sealants and surface sizes and pulp sizes. The invention further concerns a method for storing of precipitated calcium carbonate particles having an average diameter in the nanometer range.

摘要： The present invention is directed to an article of manufacture, which can be a fiber and or a film. In one aspect, the fiber or the film comprises a polyvinyl alcohol (PVOH) and an inorganic filler comprising particles having an average diameter of less than about 20 micrometers. The PVOH has a degree of hydrolysis of greater than about 95% and is present in a range between about 20 wt. % and about 99 wt. % based on the total fiber weight. Methods of making the fibers and films are also disclosed.

摘要： The present disclosure provides scalable nanotube fabrics and methods for controlling or otherwise adjusting the nanotube length distribution of a nanotube application solution in order to realize scalable nanotube fabrics. In one aspect of the present disclosure, one or more filtering operations are used to remove relatively long nanotube elements from a nanotube solution until nanotube length distribution of the nanotube solution conforms to a preselected or desired nanotube length distribution profile. In another aspect of the present disclosure, a sono-chemical cutting process is used to break up relatively long nanotube elements within a nanotube application solution into relatively short nanotube elements to realize a pre-selected or desired nanotube length distribution profile.

摘要： A process for making absorbent towel paper webs is provided. The process has the steps of (a) providing a papermaking furnish having from about 45% to about 90% by weight of the dry fiber basis of the absorbent towel paper web of a refined softwood pulp fiber mixture having from about 20% to about 89.9% by weight of softwood pulp fiber, from about 0.05% to about 20% by weight of cellulose nanofilaments, and from about 0.05% to about 5.0% by weight of strengthening additive, and from about 10% to about 55% by weight of the dry fiber basis of the absorbent towel paper web of a hardwood pulp fiber mixture; (b) forming a wet fibrous web from the paper making furnish; and, (c) drying the web until the web contains not more than about 10% by weight moisture.
