Nuclear Magnetic Resonance Under Extreme Conditions, Anand Prashant Dwivedi
Theses and Dissertations
Nuclear Magnetic Resonance (NMR) is a prime characterization tool used to understand the structures and interactions in organic molecules, crystals, as well as non-crystalline materials. However, until now, the combination of NMR with high-pressure instrumentation such as Diamond Anvil Cells (DAC) was deemed unfeasible due to the high spatial and electrical costs of standard NMR electromagnets or the regular refill of cryogenic liquids for superconducting magnets. Standard NMR techniques also raises technical difficulties when combining high-pressure instrumentation with high-temperature techniques such as laser heating. In the first part of this thesis, we present the development of a low-cost and space-saving …

Nuclear Magnetic Resonance Characterization Of Dynamics In Novel Electrochemical Materials, Christopher T. Mallia
Theses and Dissertations
As our daily use of electronics and electronic technology grows, so does the societal need for sustainable, renewable and portable electrical power. To this end, materials of interest in the electrochemical world are needed to advance the frontier of battery science and energy storage technologies so that a safer, more efficient and reliable electrical future can be realized. This work focuses on characterization of materials primarily of interest for use as electrolytes in rechargeable Lithium-Ion Batteries (LIBs). Despite their extraordinary power, LIB application in certain fields, such as in electric vehicles, has been limited due to performance and safety concerns. …
