A laboratory liquid handling system includes a pipetting module, a lab member, and a drive system. The pipetting module includes a pipettor including a pipettor shaft and a pipetting tip extending from an end of the pipettor shaft. The lab member includes a body and at least one adapter structure including an interlock feature configured to laterally receive and interlock with the pipettor shaft to releasably secure the lab member to the pipettor shaft. The drive system is operable to: selectively move the pipettor shaft laterally relative to the interlock structure to engage the pipettor shaft with the interlock structure to secure the lab member to the pipetting module; move the pipetting module to transport the lab member secured thereto; and selectively move the pipettor shaft laterally relative to the interlock structure to disengage the pipettor shaft from the interlock structure to thereby release the lab member.

A configurable mutual exclusion function oversees movement of appliances mobile over a common physical space in an automated laboratory workstation. A configurable mutex is allotted for each moveable appliance and is configurable to protect a task site when obtained for the respective appliance.

A method of preparing a porous cathode structure for use in a molten carbonate fuel cell begins by providing a porous integral plaque of sintered nickel oxide particles. The nickel oxide plaque can be obtained by oxidizing a sintered plaque of nickel metal or by compacting and sintering finely divided nickel oxide particles to the desired pore structure. The porous sintered nickel oxide plaque is contacted with a lithium salt for a sufficient time to lithiate the nickel oxide structure and thus enhance its electronic conductivity. The lithiation can be carried out either within an operating fuel cell or prior to assembling the plaque as a cathode within the fuel cell.

A high temperature, ceramic composition having electronic conductivity as measured by resistivity below about 500 ohm-cm, chemical stability particularly with respect to cathode conditions in a molten carbonate fuel cell, and composed of an alkali metal, transition metal oxide containing a dopant metal in the crystalline structure to replace a portion of the alkali metal or transition metal.

A porous sintered tile is formed of lithium aluminate for retaining molten lectrolyte within a fuel cell. The tile is prepared by reacting lithium hydroxide in aqueous solution with alumina particles to form beta lithium aluminate particles. The slurry is evaporated to dryness and the solids dehydrated to form a beta lithium aluminate powder. The powder is compacted into the desired shape and sintered at a temperature in excess of 1200 K. but less than 1900 K. to form a porous integral structure that is subsequently filled with molten electrolyte. A tile of this type is intended for use in containing molten alkali metal carbonates as electolyte for use in a fuel cell having porous metal or metal oxide electrodes for burning a fuel gas such as hydrogen and/or carbon monoxide with an oxidant gas containing oxygen.
