Abstract: In accordance with aspects of the present disclosure, a printhead assembly arranged to dispense ultraviolet curable ink or gel ink and method thereof is disclosed. The printhead assembly includes a plurality of functional plates stacked together; a first adhesive layer arranged between adjacent functional plates to provide bonding between the plates; and a second adhesive layer arranged between adjacent function plates to provide chemical resistance to the ultraviolet curable ink or the gel ink.

Abstract: A printhead assembly comprises a plurality of plates stacked together. The plates form a flow path having an inlet and a nozzle. An ejection chamber is in fluid connection with the flow path. A diaphragm is in operable connection with the ejection chamber. A micro actuator is in operable connection with the diaphragm, the micro actuator being configured to actuate the diaphragm. An adhesive layer bonds at least two of the plurality of plates together. The adhesive comprises silicone.

Abstract: Silica aerogels with improved properties are disclosed together with methods for synthesizing such aerogels. The improved properties include lower thermal conductivity (better insulating capacity), lower acoustic velocity, lower dielectric constant and improved ductility. Greater tunability of the refractive index can also be achieved. The silica aerogels are prepared by a sol-gel processing method that provides better control of the formation of aerogel structures. Generally speaking, the improvements arise from control of the synthesis to create a morphology of primary clusters and diverse-sized secondary clusters of dense silica aerogels separated by less densely packed regions. By providing a broader range of secondary clusters and/or pore sizes and loose connectivity between clusters, reductions can be achieved in thermal conductivity and flexural modulus.
