Ion Beam Analysis (IBA) techniques were used to assign nine years of PM2.5 observations to seven source types, at Lucas Heights, a topographically complex urban fringe site of Sydney. The highest contributions to total PM2.5 were from motor vehicles (Autos, 26.3%), secondary sulfur (2ndryS, 23.7%), a mixture of industry and aged sea air (IndSaged, ...
This paper presents the electrical assessment and modeling of the discharge process in RF MEMS capacitive switches with nanocrystalline diamond dielectric film. The assessment is performed by taking into account the detailed dc electrical characterization of the dielectric film at different temperatures with the aid of metal–insulator–metal (MIM) c...
This work presents a temperature-dependent and time-resolved X-ray and neutron diffraction study of the thermally induced structural rearrangement of γ-MnO2. Here, we study electrochemically prepared γ-MnO2, the manganese dioxide phase used in the majority of battery applications, which we find to be ∼64% ramsdellite [a = 4.4351(6) Å, 9.486(2) Å, c...
A series of seven 2:1 molecular complexes of urea (U) and methyl ureas with di-carboxylic acids (A) are reported, along with the results of their study by variable temperature diffraction. These all contain short, strong O–H⋯O hydrogen bonds and a recurring acid⋯amide heterodimer forming U–A–U synthons. Despite differences in the degree of saturati...
A neutron scattering investigation of the magnetoelectric coupling in PbFe_{1/2}Nb_{1/2}O_{3} (PFN) has been undertaken. Ferroelectric order occurs below 400 K, as evidenced by the softening with temperature and subsequent recovery of the zone center transverse optic phonon mode energy (\hbar \Omega_{0}). Over the same temperature range, magnetic c...
Latest results of 3G28 triple-junction solar cells manufactured by AZUR SPACE Solar Power GmbH under low intensity low temperature (LILT) conditions are reported. Excellent beginning of life efficiencies (BOL) in the order of 35% at 50W/m2 and 150°C have been realized on a large number of cells with standard and LILT optimized design. Furthermore, ...

The formation of silico-ferrite of calcium and aluminum (SFCA) and SFCA-I iron ore sinter phases during heating and cooling of synthetic iron ore sinter mixtures in the range 298 K to 1623 K (25 °C to 1350 °C) and at oxygen partial pressure of 5 × 10−3 atm has been characterized using in situ synchrotron X-ray diffraction. SFCA and SFCA-I are the k...
