Assessing the effect of O2 dithering on CH4 oxidation on Pd/Al2O3

Under periodic lean/rich operation generated by repeated O2 pulses (O2-dithering), the abatement of CH4 and NO is enhanced compared to static operation. However, it is not well understood how the dithering parameters (pulse amplitude and frequency) affect ...

Electron-phonon driven unconventional superconductivity: The role of small Fermi energies and of nonadiabatic processes

Claudio Grimaldi

The very concept of high-T-c superconductivity has originated from the discovery of superconductivity in copper oxides by Bednorz and Muller in 1986. Soon after their discovery, cuprates were recognized as undoubtedly complex and radically unconventional s ...
