The changes in the surface phase and the morphology of nickel–yttria stabilized zirconia (YSZ) cermet anodes for solid oxide fuel cells (SOFCs) upon exposure to a fuel containing 100 parts per million (ppm)-level hydrogen sulfide (H2S) at elevated temperatures were investigated using in situ Raman microspectroscopy as well as ex situ techniques such as X-ray diffraction (XRD), scanning electron...
The VERITAS array is a set of four imaging atmospheric Cherenkov telescopes (IACTs) sensitive to gamma rays with energies above 80 GeV. Each telescope based on tessellated mirror, 12 metres in diameter, which reflects light from gamma-ray-induced air shower form an image pixellated ‘camera’ comprising 499 photomultiplier tubes. brightness the primary measure ray’s energy so knowledge mirror ref...
An extensive database of in situ measurements wave impact pressure on the wall a composite breakwater and associated explanatory variables (i.e., waves, wind, water level) was collected particularly high-energy environment. Due to bottom profile, which includes wide mound concrete blocks with seaward edge that rises Lowest Astronomical Tide level over large distance, most waves break before rea...
[1] We compare tropospheric measurements of nitrogen dioxide (NO2) and formaldehyde (HCHO) from the Global Ozone Monitoring Experiment (GOME) satellite instrument with in situ measurements over eastern Texas and the southeast United States. On average, the GOME and in situ measurements of tropospheric NO2 and HCHO columns are consistent despite pronounced sampling differences. The geometric mea...
In this study, characteristic optical sizes of ice crystals in synoptic cirrus are determined using airborne measurements of ice crystal size distributions, optical extinction and water content. The measurements are compared with coincident visual observations of ice cloud optical phenomena, in particular the 22◦ and 46◦ halos. In general, the 5 scattering profiles derived from the in-situ clou...
