Dissolution Dynamic Nuclear Polarization provides a 10’000-fold gain in sensitivity but is incompatible with multi-scan experiments. Our ambition is to turn d-DNP into a new version widely compatible with NMR spectroscopy by replenishing hyperpolarization with a compact instrumentation for melt-DNP. Here I present the performances of the 1T polarizer using water-soluble radicals and porous matrices.

EPR and DNP-enhanced 13C NMR measurements on our home-built dual DNP/EPR spectrometer reveal unknown properties of substitutional nitrogen centers in diamond, which are used to interpret their DNP spectra. High field EPR data is shown indispensable for both diamond defect spin system characterization and DNP spectral analysis.

Host-guest interactions in MOFs are key to their performance in various applications. Solid-state NMR can probe these interactions, however, with limited sensitivity. I will demonstrate how endogenous metal-ion DNP can tackle this challenge, keeping MOF pores empty for guests, and discuss the effect of MOFs mobility and molecular O2 on the DNP efficacy.

Nitrogen-vacancy (NV) and silicon-vacancy (SiV) color defects in diamond carry multiple charge states that possess various electronic, optical and spin properties important for quantum technology. We demonstrate that high-voltage pulses shift chemical potential and convert the charge states of NV and SiV centers with the transition rates of ∼ MHz.

In this work we present ways to minimize the perturbation of the applied magnetic field by optimizing solid-state NMR probe structures. This is achieved by a combination of simulations and experiments, which take susceptibilities of all parts in the NMR probe into account to then study the net effect upon the sample. Based on those results, modifications to NMR probes can be made, to minimize unwanted contributions. The smaller the perturbation of the applied magnetic field, the narrower the observed possible linewidth and the higher the resolution of the experiment.

Paramagnetic metal ion complexes have been demonstrated as an alternative to traditionally-used biradical polarising agents for DNP, which are typically not commercially available. Based on this, we have introduced Gd(NO3)3 as an easily accessible and inexpensive “off-the-shelf” polarising agent, providing significant sensitivity enhancements for 13C and 15N.

It’s a challenging task to detect the metabolites of designer drugs in the body. NMR spectroscopy is one of the validating techniques for its utility of metabolic fingerprinting of various designer drugs and has opened a new horizon in forensics. This paper highlights the recent developments of Nuclear Magnetic Resonance spectroscopy applied for the Forensic identification of various designer drugs.

Chemical shift imaging NMR allows us to exploit a naturally occurring gradient of commensal bacteria, mucosa and large intestinal colonocytes. Probing the metabolic crosstalk between bacteria and colonocytes in healthy and diseases (cancer) cell set-ups allows us to probe differences in the cell-cell communication on a molecular level, potentially enabling the development of novel treatment avenues for colorectal pathologies.

Metal halide materials offer optoelectronic tunability through compositional variation but feature complicated phase behaviour and dynamic properties, with the halide site being integral to such behaviour. We use bromine NMR, NQR, and DFT to study a series of cesium lead bromides and extend these insights to the analogous Cl/I materials.

We use quantum optimal control algorithm to improve XiX DNP. The optimized DNP sequences with initial pulse lengths of 12 and 20 ns gave enhancements 2.4 and 1.6 times greater than XiX DNP, respectively. The challenges and anomaly between the numerical simulations and experiments will be addressed in the poster.
