Employing in situ solid-state NMR spectroscopy and label tracing, we elucidated the pathways of methane transformations over copper-containing zeolites. Reaction of methane with copper(II)-oxo sites leads to partial oxidation products, namely methanol, methoxy species and dimethyl ether. These products can undergo coupling over acid sites leading to C2+ hydrocarbons.

Generation of formate on the surface of supported ionic liquid phases (SILPs) is related to the catalytic selectivity of hydrogenation reactions. We use solid-state NMR to study molecular interactions between formate and different SILPs. The findings indicate electrostatic interactions which explain the improved immobilization of formate on the surface.

In recent years Pulsed Field Gradient NMR techniques to get Diffusion decays of materials have been successfully adopted in the polymer chemistry community as a sizing technique. It has many advantages over the previous gold standard in the field (size exclusion chromatography) although it has its own drawbacks and difficulties. Here we will focus on applications of NMR for Polymer material characterisation and the limitations thereof.

This groundbreaking study reveals that people who are born deaf having unique brain strengths. Using advanced MRI to study cortical morphology, we found remarkable neuroplasticity. These findings highlights the brain incredible ability to adjust and open doors for better education and therapy for the deaf community.

We explore the use of adiabatic inversion techniques to enhance the integrated solid effect (ISE). By carefully controlling the system parameters, we demonstrate how adiabatic inversion can be leveraged to improve the efficiency of polarization transfer via ISE. The findings have important implications for the development of triplet-DNP.

P1 center diamonds provide robust polarization for RT DNP, featuring unique spin properties and extended coherence and relaxation times. Our MAS-DNP experiments at 14.1 T (298K to 30K) reveal their efficiency and novel characteristics, showcasing their potential for NMR imaging and bio-NMR studies.

I will showcase some of the improvements we have made to the MAS-DNP user program instrumentation over the last few years. This includes upgrades to the cooling cabinet and the 3.2 mm custom MAS-DNP probe.

Dynamic nuclear polarization (DNP) boosts NMR sensitivity but suffers from electron-electron (e-e) interactions, reducing polarization transfer efficiency. We propose the Magic-NOVEL sequence to counteract these effects. Evaluating Lee-Goldburg NOVEL sequences, our theoretical and simulation results show enhanced electron-to-nucleus polarization transfer by weakening e-e interactions, improving DNP efficiency.

Hyperpolarizing polymers (HYPOPs) are porous epoxy-amine polymers with covalently grafted nitroxide radicals. Their use in our HypFlow project aims to enable repeating multiple cycles of freeze-DNP-melt and liquid state analysis of a pure and undiluted sample. This work presents the first results of HYPOPs recorded in our 1 Tesla benchtop DNP polarizer operating at 77 Kelvin.
