A preform for a container comprises a polymer composition which includes tungsten oxide particles, for example WOor WO.

Polymeric materials

The invention provides a polishing pad and a method of using the polishing pad for chemically-mechanically polishing a substrate. The polishing pad comprises at least a grooved region and an exclusion region, wherein the exclusion region is adjacent to the circumference of the polishing pad, and wherein the exclusion region is devoid of grooves.

CMP polishing pad having edge exclusion region of offset concentric groove pattern

The present invention provides a method of recycling a water-based wire saw cutting slurry waste fluid comprising abrasive particles and waste solids in a water-based carrier. The method comprises the steps of (a) separating the waste fluid into a first fraction and a second fraction, the first fraction comprising recovered abrasive particles, and the second fraction comprising waste solids and a portion of the water-based carrier; (b) optionally, separating the second fraction to separate the waste solids from the water-based carrier to form a waste solids portion and a recovered water-based carrier portion; (c) optionally, drying the first fraction from step (a) and separating the resulting dried abrasive particles from smaller waste particles to produce a purified recovered abrasive fraction; and (d) suspending particles of the first fraction from step (a), the purified recovered abrasive fraction from step (c), or both, in a suspending medium comprising at least a portion of the recovered water-based carrier from step (b), to generate a recycled water-based wire saw cutting slurry.

Disclosed are compositions that include a binder and non-stoichiometric tungsten oxide particles dispersed in the binder. The tungsten oxide particles have an average primary particle size of no more than 300 nanometers. The compositions are transparent and colorless.

Transparent, colorless infrared radiation absorbing compositions comprising nanoparticles

Blends of carbon black or other fillers is described. The blends of carbon black or other fillers are preferably pre-blended prior to introducing the blend into a product such as an elastomeric or polymeric product.

Blends of carbon blacks and products containing the same

Granulated products are provided and include carbonaceous particles and a carbonized agent or binder. The agent or binder is preferably a synthetic resin, pitch component, or mixture thereof. Packing materials for packing columns used in chromatographic separations are also provided as are methods of chromatographic separation using the materials. In addition, methods are provided to provide a variety of different types of carbonaceous products. A variety of chemical groups can be, prior to heat-treatment and/or thereafter, attached to the granules to form modified granules.

Material for chromatography

Methods of producing carbon black in a multi-stage reaction are described. Also described is carbon black formed from the processes.
