Surface treated silica containing particles are combined with a resin to form a liquid prepolymer composition for use in additive manufacturing. A surface treatment on the silica containing particles may participate in polymerization of the composition. The silica containing particles may be colloidal silica or a silica polymer composite particle.

Composition for liquid-based additive manufacturing

Metal-oxide composite particles are used as a toner additive.

Toner additives comprising composite particles

Surface treated modified carbon black particles and oil-based drilling fluids are described. The carbon blacks are incorporated into the oil-based drilling fluids to reduce the electrical resistivity of the oil-based drilling fluids. The surface treated carbon blacks can include a hydrophobic organic group and are readily dispersible in oil-based drilling fluids.
