Despite the enormous versatility of conjugated polymers for use in optoelectronic devices and the correspondingly large number of research studies on their photophysics, understanding of the fundamental nature of the primary photoexcitations remains highly controversial. Part of the reason for this controversy stems from the fact that the photophysics of conjugated polymer films depends sensiti...

Mental and emotional health (MEH) impairment is commonly encountered in hepatitis C patients. Although the exact mechanism remains unknown, alterations in neurotransmitter and cytokine levels maybe associated with hepatitis C virus (HCV)-related MEH issues.The aim of the study was to assess association of serum biomarkers with self-reports of MEH in HCV patients before treatment and after achie...

We study the effect of polymer thickness, hole mobility, and morphology on the device properties of polymer-based photovoltaics consisting of MEH-PPV as the optically active layer, TiO2 as the exciton dissociation surface, and ITO and Au electrodes. We demonstrate that the conversion efficiency in these polymerbased photovoltaics is primarily limited by the short exciton diffusion length combin...

We experimentally demonstrate the lasing action of electrically pumped octagonal quasi-crystal microcavities formed in a layer of conjugated polymer poly[2-methoxy5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) sandwiched between two electrodes. Lasing from a point-defect microcavity is observed at a wavelength of 606 nm with a narrow linewidth of 0.5 nm, limited by the spectrometer resolu...

We have used two-photon photoemission to probe the dynamics of the long-lived triplet excitons in pristine and photo-oxidized lms of poly[2-methoxy,5-(2'-ethylhexoxy)-1,4-phenylenevinylene] (MEH-PPV). We use a rate equation model to explain the intensity dependence of the total photoelectron yield in terms of the relaxation dynamics of the triplet excitons. Observations of the pristine lms indi...

We have utilized the high spatial resolution of near-field scanning optical microscopy (NSOM) to characterize nanoscopic electronic inhomogeneity in as-cast thin films of a light-harvesting dendrimer consisting of coumarin-343 (core) and coumarin-2 (peripheral) chromophores and in thermally annealed thin films of the semiconductive polymer poly(2-methoxy5-(20-ethylhexyloxy)-1,4-phenylene vinyle...

This paper introduces a novel Internet of Thing (IoT) enabled approach for optimizing the operation costs and enhancing network reliability incorporating uncertainty effects energy management in multi-carrier Energy Hub (EH) integrated systems (IES) with renewable resources, Combined Heat Power (CHP) Plug-In Hybrid Electric Vehicle (PHEV). In proposed model, optimization process different carri...

To examine the character and variability of human cytochrome P450 (CYP) and microsomal epoxide hydrolase (mEH) gene expression in human blood cells, we used a highly sensitive, quantitative, competitive reverse transcriptase-coupled polymerase chain reaction (QC RT-PCR) assay to assess mRNA profiles for a battery of 8 genes, in peripheral lymphocytes isolated from 10 healthy donors. Of the gene...
