The present disclosure relates to saturated or primed abrasive article constructions containing an anti-loading composition which significantly reduces loading, is coatable, is durable, and is relatively inexpensive to manufacture. In particular, the use of the anti-loading compositions of the present disclosure as a size coat at least reduces if not eliminates the need for a supersize coat, while offering comparable if not superior performance and durability. The abrasive article further includes an anti-loading size layer comprising a size coat binder and wax at least partially disposed on the abrasive layer.

The present disclosure relates to an abrasive article construction containing an anti-loading composition which significantly reduces loading, is coatable, is durable, and is relatively inexpensive to manufacture. In particular, the use of the anti-loading compositions of the present disclosure as a size coat at least reduces if not eliminates the need for a supersize coat, while offering comparable if not superior performance and durability. In one aspect, the present disclosure provides an abrasive article including a backing with a first major surface and an opposing second major surface, an abrasive layer bonded to at least a portion of the first major surface, with the abrasive layer comprising abrasive particles retained in a make coat. The abrasive article further includes an anti-loading size layer comprising a size coat binder and wax at least partially disposed on the abrasive layer.

Described herein are absorbent articles and methods of making such articles. The articles are made by bonding a copolymer onto a substrate to form a core. The absorbent articles are particularly useful in personal care product, e.g., disposable hygiene products.

Absorbent articles and methods of making

Described herein are absorbent articles made by bonding a copolymer onto a substrate to form a core. The absorbent articles are particularly useful in personal care product, e.g., disposable hygiene products. In some embodiments, the absorbent article includes a first substrate; and a copolymer irreversibly bonded onto the first substrate to form a core, wherein the copolymer is derived from a polymerizable solution comprising: (a) a first monomer selected from a (meth)acrylic acid or salt thereof; (b) greater than 1 wt % of a second monomer, wherein the second monomer is a hydrophilic crosslinking monomer, and (c) a polymeric porogen.

Disposable absorbent articles comprising an absorbent material and an antimicrobial composition are disclosed. The antimicrobial composition includes a carrier comprising fatty alcohol and a poly(alkyleneoxy) polymer, and an antimicrobial agent. The antimicrobial composition may be coated on to component substrates such as nonwovens and films, that are incorporated into disposable absorbent articles, such as disposable infant diapers, adult incontinence articles, feminine hygiene articles such as sanitary napkins, wound dressings, bandages, panty liners and tampons, personal care wipes and household wipes to provide odor control, and control of microbial growth.

A method of analyzing cellular samples that include a chemically crosslinked analyte is provided. The analysis typically involves the use of mass spectrometry.

Analysis of chemically crosslinked cellular samples

Articles and methods for the high-energy desorption/ionization of various compositions are disclosed. Methods of the invention utilize porous substrates, optionally in combination with one or more surface coatings and fillers, to provide enhanced desorption of analytes. Such enhanced desorption is particularly useful in fields of analysis such as mass spectrometry. This enhanced desorption has various utilities. For example, use of the porous substrate may allow desorption to be performed without the use of chemical matrices.

Method for laser desorption mass spectrometry using porous polymeric substrates with particle fillers

A device includes a substrate having first and second major surfaces and a hub that defines an axis of rotation for the substrate, and an unvented channel having a plurality of connected compartments. Methods for using devices of the invention are also disclosed.
