Abstract: Aspects described herein include an apparatus comprising a receptacle comprising a cage dimensioned to receive a pluggable optical module into an interior volume, An opening is defined in an exterior surface of the cage. The apparatus further comprises a heat sink assembly rigidly attached to the cage. The heat sink assembly comprises a thermal interface material extending through the opening into the interior volume. The thermal interface material is configured to compress when the pluggable optical module is received into the interior volume and contacts the thermal interface material.

Abstract: An ultra-low voltage microfluidic device for manipulating droplets of liquid by inducing Marangoni stress therein includes a plurality of smart-polymer electrodes having films of smart polymer exposed at their surfaces. The surface of the smart polymer becomes hydrophobic or hydrophilic in response to different electromagnetic potentials. The smart polymer is reversibly oxidized by applying an electrical potential such that the smart polymer acquires a positive electrical charge. The oxidized smart polymer is reduced by applying an electrical potential such that it loses its positive electrical charge. The smart polymer is doped with a chemical compound having a negatively-charged end and a long-chain hydrophobic tail. The smart polymer is a polypyrrole and the dopant is a dodecylbenzene sulfonate. The microfluidic device includes a plurality of individually-addressable control electrodes, each of which is electrically-connected with smart-polymer electrodes.
