Tuesday, March 11, 2025 Magic-Angle Spinning Probes for High and Ultra-High Fields In this talk, I will describe recent progress in the development of custom-designed probes for magic-angle spinning solid-state NMR at 600, 750, 900 and 1100 MHz, including versions with improved sensitivity for 13C and 1H detection and applications to biological macromolecules including microcrystals, […]
Pulsed dynamic nuclear polarization All spectroscopic methods evolve from continuous-wave to pulsed. Magic-angle-spinning NMR in combination with dynamic nuclear polarization (MAS DNP) has, so far, been an exception. We try to change that by designing DNP pulse sequences. For the time being, pulsed DNP experiments are only possible at low magnetic fields. The basic reason […]
NMR Spectroscopy of Metal Halide Materials: Shining Opportunities& Challenging Nuclei Metal halide perovskites are a fascinating class of materials with far-reaching potential in various applications, including photovoltaics, photodetectors, light-emitting diodes, quantum sensing, X-ray detectors, and lasers. While this broad class of compounds continues to evolve, their atomic-level structure and dynamics is immensely complex due to […]
Parahydrogen-induced polarization at Low Magnetic Field Parahydrogen-induced polarization (PHIP) is a hyperpolarization method that can enhance NMR signals by several orders of magnitude. However, parahydrogen itself is NMR silent, so an important step in PHIP experiments is to convert the parahydrogen-derived singlet order into an observable magnetic state. In this educational seminar I will review […]
DNP NMR spectroscopy for biological applications Dynamic Nuclear Polarization (DNP) has revolutionized NMR spectroscopy, enabling powerful new approaches to investigate molecular structures and mechanisms in the life sciences. This tutorial offers a practical overview of biological DNP NMR spectroscopy. We begin by introducing the core components of modern DNP NMR, including instrumentation, hyperpolarization agents, sample […]
