Dynamic nuclear polarization of a glassy matrix prepared by solid state mechanochemical amorphization of crystalline substances.

SUPPORTING INFORMATION Dynamic Nuclear Polarization of a glassy matrix prepared by solid state mechanochemical amorphization of crystalline substances

Dynamic nuclear polarization with photoexcited triplet electrons in a glassy matrix.

In this decade, dynamic nuclear polarization (DNP) using equilibrated electron spin has attracted considerable attention in the fields of NMR spectroscopy and MRI as a method to enhance sensitivity. The intensity of a signal from nuclear spins is proportional to the spin polarization. DNP is a means of transferring spin polarization from electrons to nuclei, and the equilibrated polarization of...

Synthesis of Single-Crystalline Octahedral Co3O4 with Solid-State Thermal Decomposition

In this paper, single crystalline octahedral Co3O4 with dimensions about 100–500 nm and smooth surface has been prepared by solid-state thermal decomposition of cobalt(II) Schiff base complex Co((3,4-MeO-ba)2 en)Cl2 as new precursor at 450ºC under air atmosphere for 3.5 h. Surface morphology of the products were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder ...

Synthesis and Processing of SnO2, CaSnO3 and Ca2SnO4 Nanopowders by Solid-State Reaction Technique

The nanopowders of SnO2, CaSnO3 and Ca2SnO4 in the size rang of 5-70 nm have been prepared using solid-state reaction technique. The technique is convenient and inexpensive in comparison to the conventional routes of compound prepared and processing where, many steps of mixing and annealing are i...

Solid-State NMR Investigation of Compaction Induced Amorphization of Crystalline Pharmaceuticals

Solid-state NMR (ssNMR) spectroscopy has shown its indispensable capability of elucidating atomic level structures and interactions in pharmaceutical studies [1-3]. In the past one decade, it has been utilized to investigate polymorphism of pharmaceutical crystalline compounds and the phase transformations during manufactural processing. These thermodynamic transitions of active pharmaceutical ...
