MagLab NMR Seminar Series
Dear Colleagues,
Below you will find the link to the recorded NMR seminars we are hosting via zoom, in case you miss the live sessions. The first seminar featured the topic of Radioactive NMR, presented by Dr. Laura Martel of the JRC-Karlsruhe. We expect to add at least two more seminars to this library after the live presentations occur on June 23rd and 30th.
Best regards,
Jason

“Ultrahigh-field Solid-state NMR on Biological & Functional Matter: @Pre & Post Pandemic Perspectives”
Tuesday, June 30, 2020
3:30 – 4:30 PM Eastern Daylight Time

Abstract
Solid-state MAS NMR spectroscopy is a powerful technique for structure determination of biological and functional matter (materials/solids) at high-resolution. Many examples have been shown to demonstrate a nowadays “routine-like” application of this technique on many exciting systems. State-of-the-art research combines method development, instrumentation development, preparation of high-quality non-polymorphic protein preparation, choosing promising-enough functional materials to investigate.
Here, I will present my encounters with solid-state NMR and its applications on different Matter. “pre-pandemic” refers to my previous research and “post-pandemic” refers to future perspectives and possibilities @ NHMFL.

“Advancing the Magnetic Resonance Frontiers for the Study of Complex Molecules and Active Materials”
Tuesday, June 23, 2020
3:30 – 4:30 PM Eastern Daylight Time
Abstract
Nuclear Magnetic Resonance (NMR) is a versatile spectroscopic method widely used to obtain atomically resolved structural and dynamical information of biological systems, organic and inorganic molecules, and materials. The local structure and dynamics of function-determining sites are fundamental to the biological molecules as well as materials. However, the intrinsic low sensitivity in solid-state NMR is the primary roadblock in its application to systems such as catalysts for biomass energy conversion reactions, and semiconductors for solar energy harvesting. On-going developments to address the problem of sensitivity in solid-state NMR will be presented.
Since radio frequency (RF) pulse sequences play a central role in NMR and can significantly influence the sensitivity of technique, development of a RF pulse sequence for efficient polarization transfer will be discussed in the first part of the talk. The features of Cross-Polarization (CP) pulse sequence known as RESPIRATIONCP and results demonstrating its applicability to the spin systems with large anisotropic interactions (chemical shift anisotropy or quadrupolar coupling) will be presented.
In the second part, a brief introduction to a rapidly emerging hyperpolarization technique that can enhance the sensitivity of NMR by orders of magnitude is known as dynamic nuclear polarization (DNP) will be given together with its application to characterize catalytic surfaces. Furthermore, the on-going developments in DNP to further expand its scope by using microwave pulses instead of CW irradiation to optimize the electron to nuclear spin polarization transfer will be discussed. Finally, the concept and examples of endogenous DNP using paramagnetic metal centers, intrinsic to the system of interest, as the source of polarization to enhance sensitivity of the surrounding nuclear spins, will be presented.
