In order to reduce the operating temperature of solid oxide fuel cells (SOFCs), novel electrolyte materials based on CeO2 and BaCeO3 are being developed in the scientific realm. In this context, we propose a new methodology for preparing the nano-ceramic composite materials such as BaCe0.9Gd0.9O3-δ – Ce0.9Gd0.9O2-δ (BCGO–CGO) and BaCe0.8Sm0.2O3-δ – Ce0.8Sm0.2O2-δ (BCSO – CSO) as possible elec...

Synchronous generators are of two type’s salient pole type and round rotor type. The load angle curve of a cylindrical rotor synchronous machine comprises a single sine term only while in salient pole synchronous generators, power-angle characteristic has two terms. The first term is the fundamental component due to field excitation (the same as the cylindrical rotor) and the second term ...

A facile method for synthesis of amino functionalized silica coated Fe3O4 magnetic nanoparticles is introduced. For this purpose, the surface of magnetic nanoparticles (MNPs) was modified with two precursors of silica which produced amine and vinyl functional groups on the surface of magnetic nanoparticles. The modified magnetic nanoparticles were characterized by transmission electron micr...

Even as available magnetic fields for NMR continue to increase, resolution remains one of the most critical limitations in assigning and solving structures of larger biomolecules. Here we present a novel constant-time through-bond correlation spectroscopy for solids that offers superior resolution for 13C chemical shift assignments in proteins. In this experiment, the indirect evolution and tra...

This paper shows that for 24 out of 25 solid waste materials, recycling saves more energy than is generated by incinerating mixed solid waste in an energy-from-waste facility. Recycling conserves energy that would otherwise be expended extracting virgin raw materials from the natural environment and transforming them to produce goods that can also be manufactured from recycled waste materials. ...

MAS solid-state NMR experiments applied to biological solids are still hampered by low sensitivity and resolution. In this work, we employ a deuteration scheme in which individual methyl groups are selectively protonated. This labeling scheme allows the acquisition of proton carbon correlation spectra with a resolution comparable to that in solution-state NMR experiments. We observe an increase...
