A sputtering apparatus includes a substrate holder assembly configured to support a plurality of elongated substrates relative to a sputtering source. Each elongated substrate of the plurality of elongated substrates extends along a respective substrate axis. The sputtering apparatus also includes a holder drive assembly that is configured to rotate the substrate holder assembly about a holder axis. Each respective substrate axis is oriented non-parallel relative to the holder axis. Further, the sputtering apparatus includes a substrate drive assembly that is configured to individually rotate each elongated substrate about its respective substrate axis. The sputtered material is configured to be deposited onto the plurality of elongated substrates as the substrate holder assembly is being rotated about the holder rotational axis simultaneous with the rotation of each elongated substrate about its respective substrate axis.

Sputtering apparatus and related systems and methods for sputtering substrates

A system for controlling heat transfer between components. The system includes a first component and a second component spaced apart from the first component. The system also includes a thermal diode positioned between the first and second components. The thermal diode includes a negative coefficient of thermal expansion layer and a positive coefficient of thermal expansion layer. The thermal diode is configured to transition between a connected state and a disconnected state. The thermal diode is configured to transition back-and-forth between the connected and disconnected states with variations in at least one of a first temperature of the first component or a second temperature of the second component.

Systems and methods for controlling heat transfer between components

Derivatized malachite green leuco dyes for use in radio-chromic systems are described. The dyes have the following structure: in which Ar is a substituted phenyl or thiophene ring in which at least one substitution of the Ar ring is not ortho to the bond between the ring and the linking carbon, and in which R, R, R, and Rare independently selected from methyl, alkyl, or alkyl halide. The systems include the dyes in conjunction with an activator, e.g., a halogenated activator, and a carrier, e.g., a fluid carrier or an encapsulating polymeric matrix.
