Characterization of 2-methyl-8-quinolinolato gallium (Iii) chelates

We present a detailed photophysical (absorption and emission), thermal and X-ray absorption (NEXAFS) study of gallium (III) bis(2-methyl-8-quinolinolato) carboxylate (2Meq2GaOR) chelates, where OR = acetato (OAc), trifluoroacetato (OTF) and dimethylpropianato (ODMP). These materials are compared with aluminum (III) tris(8-quinolinolato) (Alq3) chelates. We show that regardless of changing the carboxylato ligand the 2Meq2 GaOR chelates have similar unoccupied (LUMO) states. This implies that charge injection should be constant in these materials when used as emitter materials in organic light emitting devices. We also present the first detailed evaluation in to the mer/fac isomerization of gallium (III) tris(2-methyl-8-quinolinolato) (2Meq3Ga) chelate in both solution and solid state, using 1H NMR and thermal studies. Unlike in Alq3, where the fac-isomer is not present in detectable amounts in a thin film, in 2Meq3Ga the fac-isomer is present approximately four times in excess. We infer that the mer-isomer interconverts to the fac-isomer in the solid state and in the gas phase

PolarEyez: A Radial Focus+Context Visualization for Multidimensional Functions

Multi-dimensional functions are characterized by a large number of parameters on which the functional value depends. They are commonly used in engineering problems such as image analysis and system modeling. Multi-dimensional function spaces are very difficult to understand due to their multi-dimensional nature and the presence of a large number of data points in the functional space. A point called the focal point is selected by the user in the vast multi-dimensional parameter space. Rays called “focal rays ” emanate from the focal point in all directions to the boundaries of the functional space. The focal rays contain functional data points. The focal point is mapped onto the center of the visualization with the focal rays arranged radially around it. The degree of detail decreases as we move away from the focal point toward the edges of the visualization in accordance with the focus+context technique. The functional values are mapped onto a color scheme with shades of green representing positive function values, and shades of red representing negative function values. Interactive features such as the ability to change the focal point, highlighting of functional values aid the user in exploring and analyzing the functional space. The algorithm, practical applications of the visualization approach and results of formative evaluation studies are also elaborated in this thesis. The contributions of this thesis are fourfold, namely, providing an overview of the functional space, equal treatment of all dimensions, improved scalability and a smooth blending of details with the overview. Acknowledgement The future belongs to those who believe in the beauty of their dreams

Exploring experiences of grief and loss after suicide of a loved one in South Asian families

This research explores the experiences of South Asian families who have experienced suicide of a loved one in the past five-years. Past research in the areas of suicide, grief, loss, and bereavement has not focused on how different cultures live through and may view these issues through a cultural lens. The research uses a qualitative narrative methodology and to explore how South Asian families understand and interpret suicide and negotiate their personal experiences of loss and grief after suicide. Individual interviews were conducted and recorded on audiotape. Participants were provided with an opportunity to explore and share their experiences of suicide of a loved one from a cultural perspective, voices that are missing in the mainstream literature. This research contributes to a broader understanding of suicide in diverse communities and how helping professionals can work towards a more inclusive practice with South Asian families who have experiences suicide.</jats:p
