Several samples were also prepared by quenching small pieces into liquid nitrogen during the foaming process.
Several samples were obtained in different deposition conditions and analyzed using XRD, SEM and EDS.
Subsequently a 5cm×5cm×100cm prototype detector was set-up and the optical performances of several samples were measured.
A computer program was developed and several samples were prepared and measured to obtain the model parameters.
The phase compositions and microstructures of several samples were investigated by X-ray powdiffractiontion (XRD) and scanning electron microscopy (SEM).
The quantitative fractions of aromatic molecules and functional groups constituting oil hydrocarbons in several samples were determined and their slight variation from sample to sample was shown.
All samples were analyzed for major ions (Na+, Ca2+, Mg2+, K+, Cl−, SO42−, NO3−, Br−) and several samples were analyzed for selected isotopes (34Ssulfate, 18Osulfate, 15Nnitrate, 18Onitrate, 2Hwater, 18Owater) as tracers.
Using this immobilization approach, several samples were examined: a core-shell Pt-on-Ru catalyst prepared from Ru black onto which Pt was spontaneously deposited, commercial Pt/Ru 50 50 nanoparticle alloy, as well as single metal Ru and Pt nanoparticle samples.
In some wells, from the same formation, several samples were received.
Several samples were obtained from the plant to examine the inactivation of microorganisms with radiation technology.
Several samples were evaluated for each concentration to the reproducibility of the measurements.
