Bone repair/regeneration is usually investigated through X-ray computed microtomography (μCT) supported by histology of extracted samples, to analyse biomaterial structure and new bone formation processes. Magnetic resonance imaging (μMRI) shows a richer tissue contrast than μCT, despite at lower resolution, could be combined with μCT in the perspective conducting non-destructive 3D investigations bone. A pipeline designed combine μMRI images samples here described applied on human jawbone...
Abstract The translational and orientational dynamics of water in carbon nanotubes has been studied by quasi-elastic neutron scattering from 300 down to 10 K. Results show that, reducing temperature below 200 K, part this behaves as a quasi-free rotor, that is, the energy such molecules becomes comparable rotational gas phase. This novel unique dynamic behavior is related appearance characterized coordination number about two, which promoted sub-nanometer axial confinement. peculiar...
The determination of penetration depth and distribution water at surfaces is essential to knowledge the state conservation Cultural Heritage items materials, such as frescoes, stone, brick, wood, paper. Water can penetrate surface an object, coming from either external or internal source, in general moisture content region cause various decay phenomena microfractures disintegration. nuclear magnetic resonance (NMR) approach be very powerful for evaluation fine arts materials. Not only...
Abstract The polyacrylamide gel is proposed here as a phantom material for NMR imaging. This substance has electrical and relaxation characteristics very similar to those of biological tissues. thermal time stabilities also make this convenient standard MRI. © 1987 Academic Press, Inc.
The proton spin-lattice relaxation time has been measured in solid CH 4 down to 0.4 K. In the ordered phase at 9 < T 20 K process is induced by librons. energy of librons (~75 K) excellent agreement with theoretical prediction Yamamoto, Kataoka, and Okada. 1 found constant within experimental error between mechanism responsible for this lower temperature region attributed adiabatic molecular reorientation molecules. cooling procedure special cases affect results.
Longitudinal and transverse relaxation time correlation (T1-T2) is employed as a nuclear magnetic resonance noninvasive characterization tool for archeological ceramics. This paper aimed at investigating whether the most relevant firing-induced changes in ceramics, including those involving pore space properties paramagnetic mineral structures, could be used markers of firing process therefore ceramics themselves. Ancient are made up naturally available clays, often rich iron impurities,...
Structure and dynamics of water confined in channels diameter few nanometer size strongly differ from the ones bulk phase. Here, we present radiowave dielectric relaxation measurements on water-filled single-walled carbon nanotubes, with aim highlighting some aspects molecular electric dipole organization responding to high spatial confinement a hydrophobic environment. The observed spectra, resulting into two contiguous processes, allow us separate interior nanotubes external water,...
AbstractTwo nuclear magnetic resonance (NMR) devices, a standard imaging apparatus and portable single-sided relaxometer (with geometry that allows non-destructive in-situ relaxation measurements on samples of any dimensions), were used to assess the hydrophobic performance an acrylic polymer (Paraloid B-72) applied as trichloromethane (chloroform) solution biocalcarenite (Lecce stone). The NMR images time distribution functions characterized by different treatments acquired for water...
NMR diffusion–diffraction patterns show that in the mildly acidified sample a rearrangement cellulose network may take place, with reduction of average macropore size and loss pore connectivity.
