NMR quantum information processing studies rely on the reconstruction of the density matrix representing the so-called pseudo-pure states (PPS). An initially pure part of a PPS state undergoes unitary and non-unitary ...

Object Paramagnetic nanoparticles, mainly rare earth oxides and hydroxides, have been produced these last few years for use as MRI contrast agents. They could become an interesting alternative to iron oxide particles. ...

In this work we applied a quantum circuit treatment to describe the nuclear spin relaxation. From the Redfield theory, we obtain a description of the quadrupolar relaxation as a computational process in a spin 3/2 system, ...

We have estimated the mass fraction of elastic and pendant chains of model poly- (dimethylsiloxane) (PDMS) networks using transverse proton relaxation in nuclear magnetic resonance (1H NMR). These experiments were compared ...

The conformational properties of ten ring-methylated N-methyl- and N,Ndimethylanilines have been studied using 13C-NMR chemical shifts and spin-Iattice relaxation times in CDCI3, and semi-empírical (AM1) quantum-chemical ...

The conformational properties of ten ring-methylated N-methyl- and N,N-dimethylanilines have been studied using 13C-NMR chemical shifts and spin-lattice relaxation times in CDCl3, and semi-empirical (AM1) quantum-chemical ...

Tomato processing chain has a world economic relevance for the food industry and the agribusiness, providing ready-to-eat products and raw material for other production chains. The product quality is depending on control ...
