The straightforward synthesis and photophysical properties of a new series of heteroleptic Iridium (III) bis(2-arylimidazole) picolinate complexes is reported. Each complex has been characterized by NMR, UV-Vis, cyclic voltammetry, and the emissive properties of each is described. By systematically modifying first the cyclometallating aryl group on the arylimidazole ligand and then the picolinate ligand, the ramifications of ligand modification in these complexes was better understood through the construction of a structure-property relationship.

Aim and Objective: Quantitative Structure- Property Relationship (QSPR) has been widely developed to derive a correlation between chemical structures of molecules to their known properties. In this study, QSPR models have been developed for modeling and predicting thermodynamic properties of 76 camptothecin derivatives using molecular descriptors. Materials and Methods: Thermodynamic properties of camptothecin such as the thermal energy, entropy and heat capacity were calculated at Hartree–Fock level of theory and 3-21G basis sets by Gaussian 09. Results: The appropriate descriptors for the studied properties are computed and optimized by the genetic algorithms (GA) and multiple linear regressions (MLR) method among the descriptors derived from the Dragon software. Leave-One-Out Cross-Validation (LOOCV) is used to evaluate predictive models by partitioning the total sample into training and test sets. Conclusion: The predictive ability of the models was found to be satisfactory and could be used for predicting thermodynamic properties of camptothecin derivatives.

Quantifizierung der links- und rechtsventrikulären Funktion Strain Imaging erweitert die klassische Volumetrie der MRT um einen sehr subtilen globalen und regionalen Funktionsparameter. Strain detektiert sehr frühe Funktionseinbußen beider Ventrikel, die visuell noch nicht erkennbar sind. Insbesondere der longitudinale Strain ist bei ischämischen und nichtischämischen Erkrankungen frühzeitig reduziert. Strain hat über die EF hinaus zusätzliche prognostische Bedeutung. Gewebecharakterisierung T1- und T2-Mapping erweitern die klassische Gewebecharakterisierung mit Late Gadolinium Enhancement (LGE) um sehr subtile quantitative Parameter, die diffuse Fibrose (T1) und Ödem (T1 und T2) widerspiegeln. Ischämiediagnostik Die Perfusions-MRT unter Vasodilatatorstress ist das genaueste Verfahren zur Ischämiediagnostik. Die MR-INFORM-Studie zeigt, dass mithilfe der Stress-MRT fast die Hälfte der Katheteruntersuchungen in einem Kollektiv mit hoher Prätestwahrscheinlichkeit vermieden werden kann. Dabei ist die Stress-MRT der FFR-basierten Strategie nicht unterlegen und genauso sicher.

Thin polycrystalline Co2FeGe films with composition close to stoichiometry have been fabricated using magnetron co-sputtering technique. Effects of substrate temperature (TS) and post-deposition annealing (Ta) on structure, static and dynamic magnetic properties were systematically studied. It is shown that elevated TS (Ta) promote formation of ordered L21 crystal structure. Variation of TS (Ta) allow modification of magnetic properties in a broad range. Saturation magnetization ~920 emu/cm3 and low magnetization damping parameter α ~ 0.004 were achieved for TS = 573 K. This in combination with soft ferromagnetic properties (coercivity below 6 Oe) makes the films attractive candidates for spin-transfer torque and magnonic devices.
