The optical degradation of encapsulants from ultraviolet (UV) radiation has historically resulted in a significant loss performance throughout the life photovoltaic (PV) module. International Electrotechnical Commission (IEC) test methods have recently been developed to screen for PV prone performance. present study was performed benchmark polymeric packaging materials relative IEC 62788-1-4 (c...

Herein, reduced graphene-oxide-supported ZrO2 and Y2O3 (rGO-ZrO2 rGO-Y2O3) nanocomposites were synthesized by hydrothermal method used as the catalysts for photodegradation of picric acid. The structural morphological properties samples characterized using an X-ray diffractometer (XRD), scanning electron microscope (SEM) with energy dispersive absorption spectroscopy (EDAX), UV-Vis spectrophoto...

In this study, we prepared graphene quantum dots (GQDs) via a green process using rice straw as carbon source. The non-toxic nature of GQDs is suitable for application in human body-related research. Furthermore, possess biodegradability and biocompatibility characteristics, indicating high suitability applications the field drug delivery. Based on fact that acid-sensitive bonds between doxorub...

The Galactic Legacy Infrared Midplane Survey Extraordinaire (GLIMPSE) is an infrared survey of the inner Galactic plane using the Infrared Array Camera (IRAC) (Fazio et al. 2004) on board the Spitzer Space Telescope (SST) (Werner et al. 2004). IRAC has four detectors, centered at approximately 3.6, 4.5, 5.8 and 8.0 μm. GLIMPSE covered a latitude range of ±1◦, and a longitude range of |l| =10◦−6...

zinc oxide (zno) nanopowders were synthesized by the sol–gel method from an ethanol solution of zinc sulfate heptahydrate in the presence of diethylene glycol surfactant. detailed structural and microstructural investigations were carried out using x-ray diffraction (xrd), high-resolution transmission electron microscopy (hrtem), field emission scanning electron microscopy (fe-sem), fourier tra...

the potential of fourier transform near-infrared (ft-nir) spectroscopy technique was applied to determine moisture and soluble solids content of shahani date fruit. spectral acquisitions were carried out in reflectance mode using a ft-nir spectrophotometer in the range of 12000- 4000cm-1. three different preprocessing methods namely: multiplicative scatter correction (msc), first and second der...

new forms of vanadium oxide nanoporous were fabricated using a simple chemical synthesis method. vanadium pentoxide (v2o5) nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. the samples were characterized by high resolution transmission electron microscopy (hrtem), field effect scanning electron microscopy (fesem) and x-ray diffraction (xrd), four...

Synchrotron radiation is best known as a source of X-rays, but it is also a source for VUV to soft-Xrays photons. However, it was realised in the early 90’s that this source can also be exploited in the infrared energy domain. Even if in some frequency regions (roughly 30 microns and below) the total photon flux emitted by the synchrotron source remains inferior to that of a thermal source, the...

Particle-size distribution and the concentration of polystyrene particles suspended in water were accurately recovered from the inversion of spectral extinction data measured with a commercial spectrophotometer. The instrument was modified by placing a spatial filter in the collection optics to prevent low-angle scattered light from affecting the measurement of transmitted power. The data were ...
