The interaction of anionic dye Acid Green 25 (AG) with cationic surfactant cetylpyridinium chloride (CPC) was studied by spectrophotometric method in 25oC and conductometric method in 25, 30, 35, 40 and 45oC. The specific conductance of dye – surfactant mixtures was measured. A decrease in measured specific conductance values of dyesurfactant mixture was caused by the formation of nonconducting...

The ultimate goal of geochemical studies of geothermal systems is to understand the physical-chemical processes responsible for their origin and evolution. The chemical composition of fluids (separated vapor and water), collected from fumaroles, hot springs and drilled wells at the Earth’s surface (25oC) is determined in the laboratory. Using the chemical geothermometers, conservation of mass, ...

Multijunction solar cells present a certain reflectivity on its surface that lowers its light absorption. This reflectivity produces a loss in electrical efficiency and thus a loss in global energy production for CPV systems. We present here an optical design for recovering this portion of reflected light, and thus leading to a system efficiency increase. This new design is based on an external...

The studies on removal of Vanadium were conducted using Granulated Activated Carbon (GAC) in combination with Chelating agents. Ethylene di-amine Tetra Acetic Acid (EDTA) and Nitrilo Tri Acetic Acid (NTA) at 25oC. The adsorption Efficiency was studied in the pH range of 2-8. The results reveals that Langmuir and Freundlich isotherms are followed during adsorption process with the chelating agen...

Background: Bacteriophages are viruses that infect bacteria and therefore are widespread in nature. Those that lyse the pathogen Salmonella enterica serovar Enteritidis (SE) should be expected in niches in which this bacterium thrives, among others the avian egg. Furthermore, bacteriophages could remain viable in this milieu. Results: Upon artificially infecting hen eggs with the SE bacteriopha...

An all-digital full-entropy True Random Number Generator (TRNG) with measured 1.3GHz operation and total power consumption of 1.5mW at 0.75V, 25oC is fabricated in 14nm FinFET CMOS. Three independent selfcalibrating entropy sources, coupled with pre-extraction correlation suppressors and a real-time BIW extractor enable ultra-low energy consumption of 3pJ/bit, while generating cryptographic-qua...

The acidity constants of the compounds, including five-membered heterocyclic (pyrrole, thiophene, furan or thiazole) ring systems were determined at 25oC in aqueous solitions, applying UV-Vis spectroscopic method that uses absorbance diagrams,. In order to explain the pKa values obtained, also the molecule conformations of the bases and their corresponding conjugate acids were investigated, app...

in recent decade, the new advanced nanofluids, composed from various particles, have attracted the attention of researchers. this class of nanofluids, which can be prepared by suspending several types (two or more than two) of nanoparticles in base fluid, is termed as hybrid nanofluids. in this work, an experimental investigation on the effects of temperature and concentration of nanoparticles ...

Evaluated spectroscopic data and level schemes from radioactive decay nuclear reaction studies are presented for 23N, 23O, 23F, 23Ne, 23Na, 23Mg, 23Al, 23Si. This evaluation A=23 supersedes the earlier one by R. B. Firestone (2007Fi02). Highlights of this following: The recommended absolute γ-ray emission probability (%Pγ) in 23Ne β-decay was reported with 3.0% systematic uncertainty 1986BrZQ. ...
