Published in 2022 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.29541

Abstract: To determine R2 and R2′$$ {R}_2^{\prime } $$ transverse relaxation rates in healthy lung parenchyma at 0.55 T. This is important in that it informs the design and optimization of new imaging methods for 0.55T… read more here.

Published in 2023 at "Protein Science"

DOI: 10.1002/pro.4630

Abstract: There is ample computational, but only sparse experimental data suggesting that pico‐ns motions with 1 Å amplitude are pervasive in proteins in solution. Such motions, if present in reality, must deeply affect protein function and protein… read more here.

Published in 2018 at "Langmuir"

DOI: 10.1021/acs.langmuir.7b04156

Abstract: A general model for nuclear magnetic resonance (NMR) relaxation studies of fluid bilayer systems is introduced, combining a mesoscopic Brownian dynamics description of the bilayer with atomistic molecular dynamics (MD) simulations. An example is given… read more here.

Published in 2018 at "ACS nano"

DOI: 10.1021/acsnano.8b01048

Abstract: The shape of magnetic nanoparticles is of great importance in determining their contrast abilities for magnetic resonance imaging. Various magnetic nanoparticles have been developed to achieve high T1 or T2 relaxivities, but the mechanism on… read more here.

Published in 2021 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.1c01410

Abstract: Organometallic molecules based on [Dy(CpR)2]+ cations (where CpR is a substituted cyclopentadienyl anion) have emerged as clear front-runners in the search for high-temperature single-molecule magnets. Within this family of structurally similar molecules, significant variations in… read more here.

Published in 2024 at "Communications Biology"

DOI: 10.1038/s42003-024-06783-5

Abstract: Bacteria constitute a significant part of the biomass of the human microbiota, but their interactions are complex and difficult to replicate outside the host. Exploiting the superior resolution of magnetic resonance imaging (MRI) to examine… read more here.

Published in 2024 at "Journal of Physics A: Mathematical and Theoretical"

DOI: 10.1088/1751-8121/ad3c82

Abstract: Unital qubit Schwarz maps interpolate between positive and completely positive maps. It is shown that the relaxation rates of the qubit semigroups of unital maps enjoying the Schwarz property satisfy a universal constraint, which provides… read more here.

Published in 2020 at "Physical Review A"

DOI: 10.1103/physreva.101.052707

Abstract: The charge relaxation of accumulated charge patches in insulating straight capillaries is investigated theoretically. The model assumes that charges accumulate only at the inner and outer insulator-vacuum interface of the capillary but not in the… read more here.

Published in 2021 at "Physical review letters"

DOI: 10.1103/physrevlett.127.050401

Abstract: A general property of relaxation rates in open quantum systems is discussed. We find an interesting constraint for relaxation rates that universally holds in fairly large classes of quantum dynamics, e.g., weak coupling regimes, as… read more here.
