Proton Magnetic Resonance and Dielectric Dispersion of Some Zeolites

Dielectric Materials in Magnetic Resonance

High permittivity materials find extensive use in high frequency communications devices due to their small size (compared to lumped element circuits), low losses and physical robustness. Recently, these types of materials have been applied in high field magnetic resonance imaging, based upon earlier work in electron paramagnetic resonance. This review article describes the basic properties of h...

Dielectric Properties of Dehydrated Zeolites

The synthetic zeolites of Heulandite group were prepared using Microwave-Hydrothermal (M-H) method at 120 ° C/30 min. The powders were characterized using X-ray Diffraction (XRD).The Zeolites were annealed at 60, 80 and 100 o C/1 hr. The d.c resistivity of Heulandite group zeolite was found to be constant upto 378K and increased as the temperature increases. Dielectric spectras (ε ’ and tanδ) o...

Proton Nuclear Magnetic Resonance Spectroscopy

Brain Proton Magnetic Resonance Spectroscopy

Magnetic resonance (MR) spectroscopy is an analytical method used in chemistry that enables the identification and quantification of metabolites in samples. It differs from conventionalMR imaging in that spectra provide physiologic and chemical information instead of anatomy. MR spectroscopy and MR imaging have their origin in nuclear magnetic resonance (NMR). NMR was first described in 1946 si...
