We have developed a process for fabricating monodisperse noble metal/rare earth disilicide core-shell nanoparticles and nanowires in regular arrays on Si(001) with a density of 5 x 10(10) / cm2, and over areas > 1 mm2. Pt deposited via physical vapor deposition on a self-assembled rare earth disilicide nanowire template combined with reactive ion etching produces arrays of nanostructures. SEM i...
Hybrid inorganic–organic solar cells typically combine a transition metal oxide and organic absorber to form the donor–acceptor pair. Here, we explore the use of a rare earth oxide to function as the inorganic component of a hybrid solar cell. Oxidized neodymium (Nd2O3) particles are combined with [6,6]-phenyl C61 butyric acid methyl ester (PCBM) to form the solar cell active layer. The short c...
The nature of trace element carriers contained in sewage and combined sewer overflow (CSO) was investigated by TEM-EDX-Electron diffraction and SEM-EDX. During dry weather, chalcophile elements were found to accumulate in sewer sediments as early diagenetic sulfide phases. The sulfurization of some metal alloys was also evidenced. Other heavy metal carriers detected in sewage include metal allo...
