XRD data are presented to show the contrast in intercalation between the polymer and the acceptors (PC70BM and ICTA). These results are correlated with fs-TAS data to show the change in the regime of recombination: while the highly intercalated blends present a high predominance of geminate recombination, the blends with ICTA predominantly present non-geminate recombination.

This thesis investigates the effect of these two processing steps on CdZnTe detectors. XPS and X-ray diffraction (XRD) were employed to study the effect of varying the CdCl 2 processing step. Increasing the degree of CdCl 2 activation and annealing treatment was found to. throughout my PhD, without his cooperation and guidance this thesis.X-ray diffraction experiments .78 Figure 34. Schematic illustration of a synchrotron showing the 1. the linear accelerator (linac) where the electrons are produced and accelerated, 2. the booster ring where the electrons are finally accelerated to 2 GeV, 3. the storage ring and 4.As water and CO were fed separately in opposite directions, an oxidation state profile of the bed was established during steady state. This oxidation state profile was determined by combining theoretical thermodynamic data with lattice parameters obtained from synchrotron in-situ x-ray diffraction (XRD).
In this research, TiO2(B) has been successfully synthesised by both a hydrothermal route and a Low Pressure Chemical Vapour Deposition (LPCVD) process. Samples were characterised using powder-XRD, Raman spectroscopy, TEM, SEM and UV-Vis spectroscopy. Phase formation mechanisms for both the hydrothermal route and LPCVD process have been proposed.Read More
I guess you are doing PhD, if this is the case and if your research involves a lot of XRD data and analysis then my advice to you would be to actually learn this technique yourself.Read More

The structures of the lead-free perovskites in the solid solution range (KxNa1-x)0.5Bi0.5TiO3 (KNBT100x) have been investigated using high-resolution x-ray diffraction (XRD) on polycrystalline samples. The room-temperature structure of Na0.5Bi0.5TiO3 (NBT) has been studied, and identified as having monoclinic Cc symmetry, with distortion very close to that of rhombohedral R3c.Read More

The aim of this PhD thesis was the development of drug delivery systems based on inorganic carriers containing carriers based on mesoporous silica. To fulfill the PhD thesis aim the following objectives were established: 1. Synthesis and characterization of several mesostructured silica-type materials 2.Read More
The patterns in which atoms are arranged in the solid state determine properties. These arrangements can be manipulated by altering parameters such as the chemical composition, temperature and magnetic field. A phase transformation is a change in the pattern of atoms. We work on phase transformations and the relationship between structure and properties.Read More
The objective of this thesis was to prepare, using sol-gel auto-combustion method using tartric and citric acid as combustion agents, investigate the structural and dielectric and catalytic properties of the perovskite-type oxides.Read More
