Under the advisement of PhD mentor Professor Joseph T. Hupp, the PI successfully used spectroelectrochemical quartz crystal microgravimetry to elucidate the mechanism of charge transport... for both aqueous and nonaqueous sytems. This was the first demonstration of proton-coupled electron transfer at oxide semiconductor interfaces. These findings were then successfully applied to a new interpretation of photoinduced electron transfer at similar interfaces, which are of importance in the field of solar energy conversion. ...

Brett etal. [103] have studied selfassembling of 1-decanethiol at the fixed positive potentials of pc-Au electrode in chronoamperometry and quartz crystal microgravimetry. The obtained layers appeared to have improved quality and were produced faster than in the open-circuit deposition. The factors possibly influencing the fine structure of monolayers observed in voltammetric reductive desorption and oxidative redeposition of long-chain alka-nethiolates, for example, hexadecanethiol (HT) and octadecanethiol on smooth Au electrodes have been discussed [104]. It has been shown that the local order of adlayer has a role to play in the formation of that fine structure. 

Li UPD on highly oriented Au(lll) electrodes has been performed [496] from LiAsFe solutions in PC using quartz crystal microgravimetry, CV, and UV-visible reflectance spectroscopy simultaneously.

In either case, the resultant negative charge generated by electron accumulation at the internal surfaces has to be balanced by cations (from the electrolyte phase) for charge compensation. Such ion insertion reactions have been studied using techniques such as voltammetry, reflectance or absorption spectroscopy, chronoamper-ometry and electrochemical quartz-crystal microgravimetry [329, 332-336]. Both aqueous and aprotic electrolytes have been deployed for these studies.
