Dye Sensitized Solar Cells (DSSC) Performance Reviewed from the Composition of Titanium Dioxide (TiO2)/ Zinc Oxide (ZnO)

This research aims to examine the influence of the composition of TiO2 and ZnO as the working electrode on the efficiency of DSSC. The working electrode is prepared by depositing TiO2 and ZnO pastes on top of the FTO glass using the doctor blade method. The samples were then heated in an oven at a temperature of 250°C for 4 hours. In this study, three TiO2/ZnO compositions were prepared and assembled into DSSC components with red spinach dye. SEM image shows that the composition of TiO2/ZnO (0:2) produces the best surface morphology that is indicated by the number and aggregate uniform pores. This is consistent with the results of testing the electrical properties of the sample. The solar cell with the working electrode composed of TiO2/ZnO (0:2) yields an efficiency of 0.0515%, higher than the composition (2: 0) and (1: 1) which respectively yields 0.0044% and 0.0015%

Communication: X-ray coherent diffractive imaging by immersion in nanodroplets

Communication: X-ray coherent diffractive imaging by immersion in nanodroplets. Structural Dynamics, 2(5), 9. doi:10.1063/1.4933297Lensless x-ray microscopy requires the recovery of the phase of the radiation scattered from a specimen. Here, we demonstrate a de novo phase retrieval technique by encapsulating an object in a superfluid helium nanodroplet, which provides both a physical support and an approximate scattering phase for the iterative image reconstruction. The technique is robust, fast-converging, and yields the complex density of the immersed object. Images of xenon clusters embedded in superfluid helium droplets reveal transient configurations of quantum vortices in this fragile system. (C) 2015 Author(s).

Ancestral diversity improves discovery and fine-mapping of genetic loci for anthropometric traits - the Hispanic/Latino Anthropometry Consortium

Hispanic/Latinos have been underrepresented in genome-wide association studies (GWAS) for anthropometric traits despite their notable anthropometric variability, ancestry proportions, and high burden of growth stunting and overweight/obesity. To address this knowledge gap, we analyzed densely-imputed genetic data in a sample of Hispanic/Latino adults to identify and fine-map genetic variants associated with body mass index (BMI), height, and BMI-adjusted waist-to-hip ratio (WHRadjBMI). We conducted a GWAS of 18 studies/consortia as part of the Hispanic/Latino Anthropometry (HISLA) Consortium (Stage 1, n=59,771) and generalized our findings in 9 additional studies (HISLA Stage 2, n=10,538). We conducted a trans-ancestral GWAS with summary statistics from HISLA Stage 1 and existing consortia of European and African ancestries. In our HISLA Stage 1+2 analyses, we discovered one BMI locus, as well as two BMI signals and another height signal each within established anthropometric loci. In our trans-ancestral meta-analysis, we discovered three BMI loci, one height locus, and one WHRadjBMI locus. We also identified three secondary signals for BMI, 28 for height, and two for WHRadjBMI in established loci. We show that 336 known BMI, 1,177 known height, and 143 known WHRadjBMI (combined) SNPs demonstrated suggestive transferability (nominal significance and effect estimate directional consistency) in Hispanic/Latino adults. Of these, 36 BMI, 124 height, and 11 WHRadjBMI SNPs were significant after trait-specific Bonferroni correction. Trans-ancestral meta-analysis of the three ancestries showed a small-to-moderate impact of uncorrected population stratification on the resulting effect size estimates. Our findings demonstrate that future studies may also benefit from leveraging diverse ancestries and differences in linkage disequilibrium patterns to discover novel loci and additional signals with less residual population stratification

The impact of debt on the financial performance of publicly listed non-financial companies in the Philippines

This study is centered on evaluating the influence of changes in levels of debt on the financial performance of companies. It will be conducted using information from all publicly listed non-financial companies in the Philippines for a period of 5 years which is from 2005 to 2009. Underlying theories regarding the study can be considered to address Modigliani and Miller\u27s (1963) theory on capital structure specifically, the factors that it has neglected. The static trade-off theory, pecking order theory, agency theory, and moderate view theory will all be integrated to build a framework that can satisfy the objectives of the study. The framework\u27s model will be developed in reference to what Abor (2007) used in his study. In general, such a model will be using measures of debt levels and firm size as independent variables that explain the behavior of dependent variables represented by measures of financial performance. The researchers will be using a causal and, at the same time, both a quantitative and qualitative research design. Panel data analysis will be adapted to generate results from the independent and dependent variables which are capital structure and financial performance, respectively. The study will generally be helping private and government organization managers (particularly those in the Philippines), current and potential investors, the academe, and other researchers interested with the topic by creating awareness and familiarity in managing capital structure, establishing benchmarks for evaluation, applying theories relevant to capital structure, and providing affirmation or refute to conflicting stances that contribute in filling out research gaps
