Efficient laser isotope sepn. is demonstrated in 2 distinct schemes. Irradn. of the collisional zone of the gas expansion provokes an isotopically selective condensation, as well as changes in the velocity distributions of the free jet. The resulting large ...
The kinetics and mechanism of the title heterogeneous halogen exchange reactions of potential atmospheric importance have been studied under molecular flow conditions in a FEP Teflon-coated Knudsen flow reactor on HX (X = Cl, Br, I) - doped ice condensed f ...
The Object Constraint Language (OCL) offers so-called non-deterministic constructs which are often only poorly understood even by OCL experts. They are widely ignored in the OCL literature, their semantics given in the official language description of OCL ...
We report on the ab-plane optical reflectance of an iodine-intercalated Bi1.9Pb0.1Sr2CaCu2O8+delta single crystal in the 80-40000 cm(-1) (10 meV-5 eV) frequency range and at temperatures between 10 and 300 K. As compared to the iodine-free Bi2Sr2CaCu2O8+de ...
The reaction I2M + hn -> I2(B) + M (M = H, N, O, I) was studied following excitation of the I2M cluster above its B state dissocn. limit. Dispersion of the I fluorescence allows for the detn. of the relative populations of a no. of the vibrational levels v ...
The organometallic approach to the functionalization of arenes and heteroarenes has recently been investigated by our group introducing modifications of the standard methods. This includes, in particular, the basicity-driven heavy halogen migration, which ...
We characterize the superionic phase transition and the lattice and electronic structures of the archetypal type-I superionic conductor alpha-AgI using extensive first-principles molecular dynamics calculations. We find that superionicity is signaled by a ...
This thesis describes experiments with one-dimensional atomic chains grown by step decoration of vicinal Pt surfaces. The objective of the research was twofold: first, to characterize metal epitaxial growth on stepped substrates; second, to make use of thi ...
The diffusion behavior of iodine in yttria stabilized zirconia (YSZ) was investigated as a function of the temperature. Iodine implantation was performed in this cubic solid solution by irradiating material samples with 1 MeV iodine ions. The distribution ...
