How do you keep supervisors and lab management informed when results are slow?
What they are checking: Whether they communicate regularly and honestly, as the posting expects.
What research idea would you propose to advance molten salt electrochemistry?
What they are checking: Whether they can develop their own ideas and proposals.
What would you do
Your cyclic voltammetry shows an unexpected peak. How do you figure out what it is?
What they are checking: Whether they can reason through impurities, side reactions and artifacts.
About the work
Walk me through how electrorefining works for recycling used nuclear fuel in a molten salt.
What they are checking: Whether they understand the core pyroprocessing steps this team develops.
What happens during oxide reduction, and what limits its efficiency?
What they are checking: Whether they understand the electrochemistry and practical problems of oxide reduction.
How would you use electrochemical impedance spectroscopy to learn something about a molten salt system?
What they are checking: Whether they can design and interpret electroanalytical measurements the posting lists.
What makes reference electrodes tricky in molten salts, and how do you handle it?
