Stabilization of parameter estimates from multiexponential decay through extension into higher dimensions

Scientific Reports, 2022
Analysis of multiexponential decay has remained a topic of active research for over 200 years. This attests to the widespread importance of this problem and to the profound difficulties in characterizing the underlying monoexponential decays.

Magnetic Field Dependence of Spectral Correlations between ³¹P-Containing Metabolites in Brain

Metabolites, 2023
Spectral correlations between metabolites in 31P magnetic resonance spectroscopy (MRS) spectra of human brain were compared at 3 and 7 Tesla, the two commonly used magnetic field strengths for clinical research. It was found that at both field strengths,

Magnetic properties of iron-filled hydrogel clusters: a model system for quantitative susceptibility mapping with MRI

Frontiers in Physics, 2023
Quantitative approaches in clinical Magnetic Resonance Imaging (MRI) benefit from the availability of adequate phantoms. Ideally, the phantom material should reflect the complexity of signals encountered in vivo.

One-Pot Synthesis of Co-Based Coordination Polymer Nanowire for Li-Ion Batteries with Great Capacity and Stable Cycling Stability

Nano-Micro Letters, 2017
Nanowire coordination polymer cobalt–terephthalonitrile (Co-BDCN) was successfully synthesized using a simple solvothermal method and applied as anode material for lithium-ion batteries (LIBs). A reversible capacity of 1132 mAh g−1 was retained after 100

Magnetic Resonance Spectroscopy

Science Progress, 2017
Since the original observation by Zeeman, that spectral lines can be affected by magnetic fields, ‘magnetic spectroscopy’ has evolved into the broad arsenal of techniques known as ‘magnetic resonance’. This review focuses on nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR), and muon spin resonance (μSR): methods which have ...

13C Chemical Shift Assignment of Solid 2-Picolinic Acid by DFT/Crystallography Integrated Approach

Chinese Journal of Magnetic Resonance, 2020
The tautomerism of organic molecules is widely observed in solution. While for solid organic chemicals, molecules often exist in the most stable tautomeric form.
