International Classification:

H01R 13/62

US Classification:

439329000

Abstract:

A device and method for fabricating a device holder for use with a standard holder body of a transmission electron microscope for use with in situ microscopy of both static and dynamic mechanisms. One or more electrical contact fingers is disposed between a baseplate and a frame, with a MEMS device making contact with the electrical contact fingers. A connector is provided to matingly engage the transmission electron microscope and the device holder to couple the device holder to the transmission electron microscope. Once clamped between the baseplate and frame, the electrical contact fingers may be separated from the template.

Abstract:

An active material composition includes a porous graphene nanocage and a source material. The source material may be a sulfur material. The source material may be an anodic material. A lithium-sulfur battery is provided that includes a cathode, an anode, a lithium salt, and an electrolyte, where the cathode of the lithium-sulfur battery includes a porous graphene nanocage and a sulfur material and at least a portion of the sulfur material is entrapped within the porous graphene nanocage. Also provided is a lithium-air battery that includes a cathode, an anode, a lithium salt, and an electrolyte, where the cathode includes a porous graphene nanocage and where the cathode may be free of a cathodic metal catalyst.
