2013 R&D 100 Winner
Poseidon 500In recent years, tools for observing nanoscale structures have improved dramatically. However, laboratory bench electrochemistry has, until now, not been able to directly observe these structures. Protochips Inc. has leveraged the imaging capability of transmission electron microscopes (TEMs) to provide this level of analytical performance. The Poseidon 500 in situ Electrochemistry System is designed to provide scientists with the flexibility needed to dynamically control in situ electrochemical experiments without sacrificing the resolving power of the TEM. The Poseidon 500 uses a pair of semiconductor chips that feature microfabricated electrodes on thin, electron-transparent windows. Samples are placed on these electrodes and electrolyte is flowed between the chips and across the electrodes, forming a liquid layer that is isolated from the vacuum environment and is thin enough to enable high-resolution imaging and analysis. The consumable nature of the chips allows the scientist to change the parameters of the experiment by selecting a different semiconductor chip.
