sol-gel and polymeric membrane electrodes, based on thiacalix[4]arene as a neutral carrier, weresuccessfully developed for the detection of vo2+ in aqueous solutions. the sol-gel and pvcmembrane electrodes exhibited linear response with nernstian slopes of 29.3 and 28.4 mv perdecade, respectively, within the vanadyl ion concentration ranges from 1.0 × 10-6 to 1.0 × 10-1mol dm-3 and from 1.0 × 1...
Abstract Prior studies show that coordinating supply chain inventories with common replenishment epochs (CRE) provides benefit for vendor and buyers. Coordination using selective discount (SD) strategy allows some buyers to participate in the coordination scheme while other buyers continue to order as earlier. This can reduce the vendor’s total cost more than that of all buyers participating an...

In this research, monocrystalline gallium oxide (Ga₂O₃) nanobelts were synthesized through oxidation of metal gallium at high temperature. An electronic device, based on an individual Ga₂O₃ nanobelt on Pt interdigital electrodes (IDEs), was fabricated to investigate the electrical characteristics of the Ga2O3 nanobelt in a dry atmosphere at room temperature. The current-voltage (I-V) and I/V-t ...
A mesoscopic methylammonium lead iodide (CH₃NH₃PbI₃) perovskite/TiO₂ heterojunction solar cell is developed with low-cost carbon counter electrode (CE) and full printable process. With carbon black/spheroidal graphite CE, this mesoscopic heterojunction solar cell presents high stability and power conversion efficiency of 6.64%, which is higher than that of the flaky graphite based device and co...
Requirements and effects of strip injection of C(4+) at 6 MeV/u into carbon ion synchrotrons are studied. The setup is composed of three chicane dipoles, one Lambertson septum, and one carbon stripping foil at a thickness of 60 microg/cm(2). The required length of the injection section is about 4.1 m. The emittance growth due to multiple Coulomb scatterings is studied.
The objective of this study was to detect the fluoride level in the drinking water and the urine of habitants aged 16-55 years living in Inner Mongolia China. Furthermore, fluoride concentration of the brick tea infusion samples which were drunk by Mongolia herdsmen in everyday life living in SumuErga village of Ejin Horo Banner, Inner Mongolia China was also determined. A total of 117 particip...
Ta-based compounds show Pt-like behavior: Binary tantalum compounds as counter electrodes (CEs) in dye-sensitized solar cells (DSCs) demonstrate Pt-like electrocatalytic activity and competitive photovoltaic performance, matching the performance of DSCs with Pt CEs. The first-principle density functional theory (DFT) calculations provide a strategy for understanding the relationship between the...
Fluoride beyond desirable amounts(0.6-1.5 mg/L) in groundwater is a major problem and fluorosis is a very dangerous and deadly disease affecting millions of people across the World (Bell and Ludwig, 1970; Adimalla and Venkatayogi, 2017; Narsimha and Sudarshan, 2013, 2017a, 2017b) [1], [2], [3], [4], [5]. The investigated area is located in north-eastern part of Medak district, Telangana state a...
BACKGROUND/AIMS Currently available techniques for fluoride analysis are not standardized. Therefore, this study was designed to develop standardized methods for analyzing fluoride in biological and nonbiological samples used for dental research. METHODS A group of nine laboratories analyzed a set of standardized samples for fluoride concentration using their own methods. The group then revie...
