Abstract: There is provided a method for sensing a sample. The method includes the following steps: first a light beam is directed onto the sample. The sample transmits at least a portion of the light beam to form a transmitted light beam. Next, the transmitted light beam is received at an acoustic transducer. The acoustic transducer absorbs at least a portion of the transmitted light beam and in response generated an acoustic wave. Subsequently, an electrical signal is generated at the acoustic transducer. The electrical signal is generated based on at least a portion of the acoustic wave.

Abstract: A pigment particle coated with at least one of a resin and a charge control surface additive, wherein the pigment particle is a pearlescent or metallic pigment. The pigment adds pearlescent effects and is of a size and charge as to be used as a toner material in electrostatographic or xerographic image formation.

Abstract: Pigment particles with at least one metal oxide surface additive, wherein the at least one metal oxide surface additive is a metal oxide particle covalently bonded with at least one polycondensation polymer, wherein the pigment particle is a pearlescent or metallic pigment.

Abstract: A toner composition includes core particles including a polymeric latex and an optional colorant, and amino-containing polymer particles dispersed on an external surface of the particles.

Abstract: Toner including toner particles having a calcium-containing material at least in a surface portion of the toner particle, wherein the toner particles contain calcium in an amount of from 20 ppm to about 300 ppm of calcium by dry weight of the toner. Developer including a carrier and a toner, wherein the toner includes toner particles having a calcium-containing material at least in a surface portion of the toner particles. In an emulsion aggregation process for making toner particles, the toner particles are treated with calcium. The addition of calcium to the toner particles improves toner performance by lowering cohesion and charging, thereby generating an image of high gloss.
