A nucleic acid amplifier may include a sample preparation zone, a fluid ejector, an amplification zone and a capillary break between the amplification zone and the fluid ejector.

Nucleic acid amplification

In an example implementation, a method of dispensing fluid from a fluid dispensing device, includes receiving a dispense head at a receiving station, and receiving a notification that a supply slot in the dispense head has been filled with fluid. The method includes vibrating the dispense head to move fluid through a microfluidic channel from the supply slot into an ejection chamber of the dispense head, and providing a dispense signal to cause an ejection mechanism disposed within the chamber to eject an amount of the fluid from the dispense head.

Vibrating a dispense head to move fluid

A coating composition for optical recording includes a uniform dispersion of polymer particles in a liquid, a quantity of dye particles uniformly dispersed in the liquid, the dye particles being soluble in the polymer but substantially insoluble in the liquid, and a quantity of radiation absorber material adapted to absorb radiation at a wavelength of a laser for optical recording of an image.

Coating for optical recording

An optical recording medium, comprises a substrate, an imaging composition disposed on said substrate, said compound comprising: a matrix, a color-forming agent, and a nucleating agent. The nucleating agent increases the nucleation density of at least one component of the color-forming agent.

Inks for use on optical recording media

Various embodiments of a method, coating and system for conductive patterning are disclosed.

Conductive patterning

A radiation image-able coating includes a curable polymer matrix, a metal complex disposed in the curable polymer matrix, wherein the metal complex is configured to form localized metallic particles when exposed to heat.

System and method for radiation imaging by in-situ particle formation

The present disclosure discloses a color former phase. According to one exemplary embodiment discussed herein, an exemplary color former phase includes at least one color former, a radiation absorber, and an acrylic resin, in which the color former, the radiation absorber, and the acrylic resin form an amorphous solid.
