Identify all short-form words: The origins of electrogravimetry date back to the 19th century, when NAME_1, an American chemist, studied the electrolytic precipitation of copper and nickel.  This procedure was the first of its kind until NAME_2 did similar research on electric metal analysis.  Today, these two are credited with the invention of the electrogravimetry, known at the time as “electrochemical analysis,” “electroanalysis,” or “electrolytic analysis”. 
 
All methods of electrogravimetry involve a traditional NAME_3 crystal microbalance (QCM) system in which a sensor is used from an AT cut NAME_3 crystal.  The groundwork of the QCM is built upon the notion that any mass delivered on the NAME_3 electrode’s interfacial region can be detected through the resonating frequency of the vibrating NAME_3 crystal.  While most vibrational modes occurring in the AT cut NAME_3 are negligible, the vibration mode is known as thickness shear mode.  These vibrations are extremely sensitive, which permits accurate detection of atomic interactions near the sensor, allowing these techniques to be used in analytical chemistry .  
 
Through combining the techniques of QCM with classic electrochemical techniques, the electrochemical NAME_3 crystal microbalance (EQCM) was created.  EQCM is a new device used to perform the process of electrogravimetry.  This device employs a high frequency acoustic wave generated by a piezoelectric resonator to store and dissipate energy infused into the device’s interfacial region.
 
Electrogravimetry has been useful in polymer studies, copper electrodeposition, gold oxidation in an acidic medium, and passivity of iron in a sulfuric medium, as well as Ionic insertion in WO3.
