We implement several non-binary logic systems using the spin dynamics of nuclear spins in nuclear magnetic resonance (NMR). The NMR system is a suitable test system because of its high degree of experimental control; findings from NMR implementations are relevant for other computational platforms exploiting particles with spin, such as electrons or photons. While we do not expect the NMR system...

Quantum information processors have the potential to drastically change the way we communicate and process information. Nuclear magnetic resonance (NMR) has been one of the first experimental implementations of quantum information processing (QIP) and continues to be an excellent testbed to develop new QIP techniques. We review the recent progress made in NMR QIP, focusing on decoupling, pulse ...

Colloidal magnetic nanoparticles (MNPs) based on a nearly monodisperse iron oxide core and capped by oleic acid have been used as model systems for investigating the superparamagnetic spin dynamics by means of magnetometry measurements and nuclear magnetic resonance (1H NMR) relaxometry. The key magnetic properties (saturation magnetization, coercive field, and frequency dependent "blocking" te...

Glycosaminoglycans (GAGs) comprise a special class of complex carbohydrates endowed with numerous biological functions. Most of these functions are regulated by conformational arrangements or dynamical properties of GAGs in solution. Nuclear magnetic resonance (NMR) is a powerful technique used for dynamic analyses. Spin relaxation, scalar couplings, chemical shifts and nuclear Overhauser effec...

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...

Nuclear magnetic resonance spectroscopy (NMR) uses a very strong magnetic field and radio frequency (RF) pulses to study the structure of molecules through the resonance frequencies of specific nuclei within the molecule. In order to characterize biochars, several solid-state techniques utilizing C and H nuclei can be used to determine the relative quantity of carbon functional groups, the appr...

The magnetic phase diagram Tc(P ) of the weak itinerant helimagnetic compound MnSi is reviewed upon a Nuclear Magnetic Resonance (NMR) experiment. We present a systematic study on the evolution of the NMR spin echo signal at T = 1.4 K of the non-magnetic silicone sites, Si, up to 17.8 kbar. The pressure effect is interpreted as a weak variation of the local electronic spin polarization and the ...

An unusual case is described linking cranial diabetes insipidus with longstanding arrested hydrocephalus. The latter was demonstrated by computed tomographic (CT) and nuclear magnetic resonance (NMR) scans and cerebrospinal fluid pressure measurements. The increasing use of CT and NMR scans may result in this association of cranial diabetes and hydrocephalus being better defined.

1 Introduction Nuclear magnetic resonance, NMR, and X-ray crystallography are the only two methods that can be applied to the study of three-dimensional molecular structures of proteins at atomic resolution. NMR spectroscopy is the only method that allows the determination of three-dimensional structures of proteins molecules in the solution phase.

The development of nuclear magnetic resonance (NMR) spectroscopy as an established research tool for noninvasive studies of cancer cells and for in vivo studies of tumors in animals and humans has led to the possibility that this technique may be used in the future for clinical research studies and monitoring of therapy in cancer patients in combination with magnetic resonance imaging. This art...
