Composite particles and a method of forming composite particles are described. The composite particles comprise at least one inorganic nanoparticle covalently bound to at least one inorganic microparticle with a linking compound. Lubricant compositions and sprayable dispersion compositions comprising composite particles are also described.

Composite particles and method of forming

The present disclosure describes compositions and a method for forming such compositions. More specifically, inorganic microparticles and surface modified silica nanoparticles are mixed to form a composition. The surface modified silica nanoparticles are present in the composition in an amount sufficient to decrease the coefficient of friction relative to a comparable composition that is free of surface modified silica nanoparticles.

Lubricant composition and method of forming

Inorganic pigment compositions comprising surface-modified nanoparticles are described, along with methods of making such compositions. Such compositions may allow the inorganic pigment to be diluted to a significant extent with non-pigmented extenders, while preserving or enhancing the coloring power of the pigment.

Inorganic pigment compositions comprising surface-modified nanoparticles, and methods of making

Powder compositions exhibiting improved flow properties. The compositions generally contain a bulk solid material in the form of a powder and surface-modified nanoparticles. Methods of improving the flow of powder compositions and devices and articles made using such compositions are also disclosed.

Compositions exhibiting improved flowability

Composite proppant particles each of which comprises a plurality of microbubbles and a resin binder are disclosed. Also disclosed are a method of using such composite proppant particles to prop fractures in wells formed in underground formations.

Low density proppant particles and use thereof

The present invention provides a drilling fluid composition and a method of drilling comprising a drilling fluid, which may be oil- or water-based, and a composite microsphere component. The invention drilling fluid composition advantageously reduces the density of a conventional fluid, reduces costs associated with pumping and overcomes problems associated with conventional gas-injection processes. The invention uses conventional drilling and pumping equipment, requires no sea-floor based pumps and may be easily pressure-controlled to maintain the pressure of the fluid.

Drilling fluid containing microspheres and use thereof

Semicrystalline polymers can have predetermined amounts of their surfaces rendered quasi-amorphous by irradiation. Polymer surfaces which are so modified can display enhanced heat sealability to accept bonding to other materials.

Heat sealing of semicrystalline quasi-amorphous polymers

A heat-sealable, laminated package for hermetically sealing an object in a pouch of the package. The package has means for facilitating manual tearing the pouch along a predetermined path. The facilitating means includes two closely-spaced stiffened portions on opposite sides of the predetermined path and cut means at one end of the predetermined path for facilitating tearing the pouch along the predetermined path and between the two closely-spaced stiffened portions.
