ELECTROCHEMICAL METHODS FOR THE SUSTAINABLE RECOVERY OF GADOLINIUM FROM MRI CONTRAST AGENTS AND FOR THE FABRICATION OF GADOLINIUM-RICH NANOPARTICLES.
The widespread use of gadolinium-based contrast agents (GBCAs) in magnetic resonance imaging (MRI) has led to increasing concern over the release of gadolinium into the environment. Gadolinium (Gd) is excreted in complexed forms that are stable and difficult to remove through conventional …

Heat capacity of gadolinium near the Curie point
"The dependence of the heat capacity of gadolinium on temperature has been observed close to the ferromagnetic Curie point at about 180 C. An ""ac"" or temperature modulation method allowed the use of very small single crystal samples. The heat capacity peak for our best sample is rounded in a …

Magnetic resonance characterization of gadolinium-based contrast agents
… methods have been used for characterizing gadolinium-based contrast agents in NMR Imaging in this thesis. Many Gd-based contrast agents were studied including Gd DTPA(dimethylenetriaminepentaacetic acid). The zero field splitting energies and g values of Gd complexes were obtained in frozen …

Computer Aided Analysis of Late Gadolinium Enhanced Cardiac MRI
… Among various clinical cardiac scans, late gadolinium enhanced (LGE) cardiac magnetic resonance (CMR) imaging can directly visualize and thus discriminate non-viable myocardium (i.e., infarcts) from normal myocardium via hyper-enhanced intensities. Since manual analysis of LGE CMR images is …

Growth and characterisation of Niobium/Gadolinium superconductor-ferromagnet nanocomposites
Superconductivity and ferromagnetism are two antagonistic physical phenomena which their coexistence in a uniform material can be resolved only under extraordinary conditions. The reason for that is the phonon-mediated attraction energy between electrons which results in the formation of the …

Brillouin scattering from single-crystal dysprosium and gadolinium films
Brillouin light scattering studies have been made on the temperature dependence and dispersion of long-wavelength acoustic phonons in single-crystal Dy films and long-wavelength acoustic magnons in single-crystal Gd films. The spectra were analyzed by using elastic and magnetic continuum models for …

A comparison of three gadolinium based approaches to cancer therapy
… on using compounds containing the element gadolinium (Gd), which produces internal conversion and Auger cascade electrons upon absorbing thermal neutrons. The low energy, nanometer-range, Auger electrons are absorbed locally and significantly increase cell killing when Gd binds to DNA. Two …

Gadolinium Endohedral Metallofullerenes for Future Magnetic Resonance Imaging Contrast Agents
Gadolinium endohedral metallofullerenes (EMFs) have shown the potential to become next generation magnetic resonance imaging (MRI) contrast agents due to their significantly improved efficiency and safety, as well as multi-day body retention which allows for a longer surgery and observation …

Electron paramagnetic resonance spectroscopic study of two gadolinium centres at calcium sites in synthetic fluorapatite
Gd-doped fluorapatite, synthesized from CaF₂-rich melts, has been investigated as single crystals and powder samples by using X-band (9.5 GHz) and W-band (95 GHz) electron paramagnetic resonance (EPR) spectroscopy. Gd₂O₃ with natural abundances of isotopes and ¹⁵⁷Gd-enriched Gd₂O₃ were used in the …
