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...
background: in this study the basic radiation properties of n-isopropylacrylamaide polymer gel dosimeter were determined together with verification of its soft tissue equivalency. materials and methods: the nipam gel was prepared and irradiated approximately 2 h after manufacturing. the magnetic resonance (mr) images were made 24 h after irradiation. the nuclear magnetic resonance (nmr) respons...
Effects of Peach Cultivar on Enzymatic Browning Following Cell Damage from High-Pressure Processing.
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)...
this paper is the first multi-scale characterization of the fluidize-dried gum extracted from the fresh fruits of the plant abelmoschus esculentus. it describes the physical, thermal, sorptional and functional properties of this natural gum. elemental analysis, scanning electron microscopy (sem), particle size analysis, x-ray powder diffraction (xprd), thermo-gravimetric analysis (tga), differe...
introduction: biofilm forming staphylococcus epidermidis is a main causative agent of infections related to medical devices. purification and evaluation of gly-ta polysaccharide from a biofilm-forming s. epidermidis as a putative vaccine candidate were the main goals of the current study. methods: taking advantage of size exclusion chromatography procedure, glycerol teichoic acid (gly-ta) was p...
