要旨

Magnetic resonance force microscopy (MRFM) is a promising method to obtain magnetic resonance images with nanometer resolution. One of the factors currently limiting its application to compounds with strong and possibly time-dependent dipolar couplings is the imperfect efficiency of the adiabatic inversion sweeps and the concomitant loss in the signal to noise ratio. We describe significant improvements to previous MRFM excitation schemes. Applying these schemes to a polymer blend of 80% PEEK and 20% PTFE allowed acquiring full-volume two-dimensional (2D) spatial images (with Hadamard multiplexing) of both the 1H and 19F-rich phases with a 6-fold enhancement in the SNR.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
