This measures the fluid pressure and collects small samples in a well.

Molten carbonate fuel cells have an electrolyte of molten carbonate salt and operate at temperatures in the region of 600C to 700C. Negatively charged carbonate ions carry the current through the membrane separating the electrodes, which have a standar electrical connection. MCFC systems are fuelled by hydrogen.

An alloying element used as a raw material for some classes of stainless steel. Molybdenum in the presence of chromium enhances the corrosion resistance of stainless steel.

Miles per kWh (mpkWh) is the unit used in the car. Some EVs use Wh per mile (or kilometer), which is similar in concept to the litres/100km used in many places for ICE vehicle fuel efficiency.

A term that is generally synonymous with drilling fluid and that encompasses most fluids used in hydrocarbon drilling operations, especially fluids that contain significant amounts of suspended solids, emulsified water or oil.
