摘要： A process for producing positively charged polymer encapsulated particles which have a size of less than 5 μm and which include a positively charged polymer shell surrounding a core of particle. The process includes the steps of, firstly, dispersing the core particles in an aqueous solution; adding a mixture of monomers either before or after the dispersion step; then, polymerizing the monomers in view of obtaining polymer encapsulated particles, wherein the polymer shell of the particle includes polymers or co-polymers that have a functional group FG. Finally, the process includes the step of dispersing the encapsulated particles with surfactants and charge directors in view of obtaining positively charged encapsulated particle dispersions.

摘要： An ink forming method involves preparing a deagglomerated ink or a modified deagglomerated ink. The deagglomerated ink or the modified deagglomerated ink includes at least deagglomerated colorant particles and a liquid component. The deagglomerated colorant particles are chosen from pigment particles each encapsulated with a dispersant. The colorant particles have a particle size ranging from about 50 nm to about 500 nm. Prior to shipping and/or storing the deagglomerated ink or the modified deagglomerated ink, a portion of the liquid component is removed to form a concentrated ink that has a nonvolatile solids content ranging from about 40 wt % to about 90 wt % of the concentrated ink.

摘要： A thin film semiconductor and a method of its fabrication use induced crystallization and aggregation of a nanocrystal seed layer to form a merged-domain layer. The nanocrystal seed layer is deposited onto a substrate surface within a defined boundary. A reaction temperature below a boiling point of a reaction solution is employed. A thin film metal-oxide transistor and a method of its production employ the thin film semiconductor as a channel of the transistor. The merged-domain layer exhibits high carrier mobility.

摘要： An additive manufacturing apparatus includes a platform, a dispenser to deliver a plurality of layers of feed material, one or more light sources configured to emit a first light beam and a second light beam, and a polygon beam scanner including a rotatable mirror having a plurality of reflective facets to redirect the first light beam and the second light beam toward the platform to deliver energy to an uppermost layer of feed material. The mirror is positioned and rotatable such that motion of each facet of the plurality of reflective facets causes the first light beam to sweep along a first path on the uppermost layer and causes the second light beam to sweep along the first path following the first light beam.
