The output energy estimation of photovoltaic (PV) modules was carried out using contour maps as a function of average photon energy (APE), which is an index of solar spectral irradiance and module temperature ( T mod ) in our previous report. This method is useful for not only crystalline Si PV modules but also thin f…
The effects of bismuth (Bi) incorporation into Cu(In 1- x ,Ga x )Se 2 (CIGS) thin films and solar cells have been investigated. 10–50-nm-thick Bi thin layers were deposited onto Mo-coated soda-lime glass (SLG) and SiO x -coated SLG substrates by vacuum evaporation. CIGS thin films were then deposited by a three-stage…
Abstract- Graphene field effect transistors (GFETs) fabricated on undoped semiconductor substrates have shown promise for sensing ionizing radiation with a potential of high sensitivity, low noise, low power, and room temperature operation. Radiation detection with GFET is based on the high sensitivity of graphene res…
Resistive switching random access memory (RRAM) offers fast switching, high endurance and CMOS-compatible integration. Although functional devices below 10 nm have been already demonstrated, assessing the ultimate scaling of RRAM requires a detailed understanding and modeling of switching and reliability processes. Th…
We report Quantum dot based light emitting diodes (QD-LEDs) fabricated under the optimized annealing conditions of TiO2 films used as the electron transport layer (ETL) in the device. Films of different thicknesses were fabricated by varying annealing conditions leading to the improved electrical properties in QD-LEDs…
Yttrium is one of the most widely used dopants (e.g., in yttrium-doped ceria (YDC) and yttria-stabilized zirconia) for improving performance of solid electrolytes utilized in solid oxide fuel cells. Oxygen ion conductivity is known to be a function of yttrium concentration in the electrolytes and thus it is important…
Abstract Nitrate reduction on well-oriented platinum surfaces modified with Bi adatoms has been studied. The quantification of the electrocatalytic enhancement of the reaction rate due to the presence of Bi at different coverages was made on Pt(111) and the vicinal surfaces Pt(554) and Pt(332). These contain 9 and 5 a…
In this research, ZnO nanocrystals were prepared in a few hours by solochemical processing using sodium hydroxide and zinc nitrate hexahydrate as raw materials. Different reaction temperatures have been investigated and revealed their effects on the crystallite size, morphology and crystalline phase of ZnO nanocrystal…
Pharmaceutical formulations that contain nanosized drugs are perceived as "Nanopharmaceuticals" and offer significant benefit for the patient compared to the conventional formulated drugs. There are several advantages of nanoparticular drug formulations such as enhanced solubility and dissolution rate, enhanced oral b…
The crystal structural parameters of Nd3+-doped rare earth orthotantalate GdxLu1?xTaO4 (x = 0.85) are determined by applying the Rietveld refinement to its X-ray diffraction, and its emission and excitation spectra at 77 K are analysed. The relativistic model of ab initio self-consistent DV-X? method, which is applied…
The ultrafast carrier relaxation processes in CdTe quantum dots are investigated by femtosecond fluorescence up-conversion spectroscopy. Photo-excited hole relaxing to the edge of the forbidden gap takes a maximal time of ∼ 1.6 ps with exciting at 400 nm, depending on the state of the photo-excited hole. The shallow t…
This paper summarizes the results of a series of papers on developing methods for deter-mining elastic-dissipative characteristics of polymer composite materials (PCM) and predicting the corresponding dynamical responses from structures. For a prismatic anisotropic bar which is arbitrarily oriented with respect to the…
ClpX is a general stress protein which belongs to the heat shock protein, Clp/Hsp100 family of molecular chaperones. ClpX, in association with ClpP degrades proteins in an ATP dependent manner. Some members of the Clp family have been shown to be involved in the pathogenesis of many bacteria. The Helicobacter pylori g…
Abstract Mesoporous silica shell was formed onto supermagnetic Fe3O4 nanoparticles to produce magnetic core–mesoporous shell silica spheres (MCMSS) by using anionic surfactant for the first time in two-pot synthesis route. Costructure directing agent (CSDA) has assisted the electrostatic interaction between the partia…
Abstract A novel method for the preparation of single‐phase ammonium dimolybdate with industrial ammonium molybdate was studied. Various influential factors were evaluated in the paper, including reaction temperature, reaction time, initial molybdenum concentration, initial NH 3 /Mo molar ratio, and stirring speed. Un…
An understanding of the adhesion of microparticles, particularly microcapsules, containing a functional component to a fabric surface is crucial to an effective application of this component to the fibre. Fabric surface is very rough; hence, direct measurement of the adhesion of single microparticles to surfaces with…
The typical crystal surfaces of CuInSe2 (CISe) and related compounds were studied using density functional theory (DFT) methods. We evaluated energies and surface structures of (112), (1̄1̄2̄), (110), (102), (100), (1̄00), (001), and (001̄) surfaces on CISe. For CISe, the (112) surface had the lowest energy among thes…
Long term reliability has been an issue in the practical use of composite hollow insulators for many years and much basic research and numerous field tests have been conducted. However, very little research on the reliability of interfaces between the FRP core and silicone rubber housing of composite hollow insulators…
With the United States rethinking its strategy for the management and disposal of defense high-level radioactive waste and civilian used nuclear fuel (UNF), it is an opportune time to evaluate the near-term and long-term options and requirements for the U.S. geologic repository program. In this paper, we outline a res…
With the rapid development of nanotechnology and increasingly broad bio-application of engineered nanomaterials, their biohazards have become a serious public concern. It is believed that the chemical nature, particle size, morphology, and surface chemistry of nanomaterials are key parameters that influence their toxi…
