Konstantin Ivanov intercontinental magnetic resonance seminar series started on April 8, 2020. It organises seminars on a range of topics in magnetic resonance covering NMR, EPR, hyperpolarisation, colour centres and optical pumping, and ZULF NMR. The emphasis of the talks are on both methods and applications and a perspective on the future of the field. The speakers include a wide range of scientists ranging from PhD students to post-doctoral fellows, to senior scientists.
Upcoming Talks:
April 18, 2025, No Seminar (Good Friday)
April 25, 2025, Kai Xue, NTU, Singapore
May 2, 2025, Melanie Britton, Univ. of Birmingham, UK
May 9, 2025 (ICONS Anniversary Talk), Niels Chr. Nielsen, University of Aarhus, Denmark, "Design of pulsed DNP methods – bridging DNP and MAS solid-state NMR", I will present how broadband pulsed DNP pulse sequences can be designed systematically using effective Hamiltonian based non-linear optimization and optimal control. Focus will be devoted to the crucial balancing of linear and bilinear effective Hamiltonians in short pulse sequence elements to control spin dynamics over large bandwidths. It will be demonstrated that powerful recoupling experiments can be developed exclusively on basis of a single crystallite orientation and for static sample conditions. Broadband DNP experiments reaching a bandwidth of 100 MHz for the electron spins will be demonstrated experimentally on advanced X-band pulsed DNP instrumentation. It will be shown that the proprosed static-sample DNP experiments straightforwardly can be translated into broadband heteronuclear dipolar recoupling experiments for MAS solid-state NMR with demonstrations for 15N-13C and 2H-13C broadband transfers on 700 and 950 MHz instrumentation. This implies that MAS dipolar recoupling experiments can be developed on basis of a single-crystallite orientation and without considering MAS, which in addition to modular pulse sequence construction significantly simplifies the spin engineering process.
