development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Density of Superfluid Helium Droplets
The classical integral cross sections of large superfluid 4He N droplets and the number of atoms in the droplets (N = 103 − 104) have been measured in molecular beam scattering experiments. These measurements are found to be in good agreement with the cross sections predicted from density functional calculations of the radial density distributions with a 10–90% surface thickness of 5.7Å. By usi...
متن کاملAcoustic Simulation of Coaxial Hot Air Jets Using Cold Helium–Air Mixture Jets
This work examines the ability of small-scale helium–air mixture coaxial jets to simulate the acoustics of largescale hot air jets representing the exhaust of separate-flow turbofan engines. Experiments employed a one-eighthscale model of a separate-flow nozzle used in hot tests at NASA John H. Glenn Research Center. Comparisons were conducted for two set points using the following methods: mat...

متن کاملDetermination of Seabird Density using Marine Radar
The upper coast of Texas has potential for onshore and offshore wind farm installations. Seabirds are important apex predators of estuarine and nearshore marine ecosystems and may be impacted by electricity-generating wind turbines. The area also is a crossroads for trans-Gulf and circum-Gulf of Mexico migrating land birds. Determination of avian density on land is facilitated by laser rangefin...
