Nuclear magnetic resonance (NMR) has provided a valuable experimental testbed for quantum information processing (QIP). Here, we briefly review the use of nuclear spins as qubits, and discuss the current status of NMR-QIP. Advances in the techniques available for control are described along with the various implementations of quantum algorithms and quantum simulations that have been performed u...

A general overview of the advancements and applications of nuclear magnetic resonance (NMR) hyphenated with other analytical techniques is given from a practical point of view. Details on the advantages and disadvantages of the hyphenation of NMR with liquid chromatography as LC–NMR and also with mass spectrometry as LC–MS–NMR are demonstrated with two examples. Current developments of NMR with...

Nuclear Magnetic Resonance (NMR) is a powerful technique to probe the local environment of atoms bearing nuclear spin. Interfaces in rechargeable battery, within multi-component electrode or electrolytes between electrodes and electrolyte, are key its function lifetime. NMR spectroscopy solid phases battery participate understanding processes at these interfaces. The solid-state community still...

Peach cultivars contribute to unique product characteristics and may affect the degree of browning after high-pressure processing (HPP). Nine peach cultivars were subjected to HPP at 0, 100, and 400 MPa for 10 min. Proton nuclear magnetic resonance (1H NMR) relaxometry, light microscopy, color, polyphenol oxidase (PPO) activity, and total phenols were evaluated. The development of enzymatic bro...

Nuclear magnetic resonance spectroscopy (NMR) is a valuable tool for obtaining structural and dynamical information of molecules. However, the method suffers from poor sensitivity compared to most other types of spectroscopy. In recent years, substantial efforts have been made to improve the sensitivity of the technique. Hyperpolarization methods such as parahydrogen induced polarization (PHIP)...
