Study on the Adsorption of Samarium and Gadolinium Ions by a Biopolymer Microcapsules Containing DEHPA/TOPO Extract

In this study, the adsorption behavior of an alginate biopolymer microspheres containing D2 EHPA/TOPO (DTMCs) toward samarium (III) and gadolinium (III) ions was examined under various conditions. Scanning electron microscope (SEM) and thermogravimetric analysis (TGA) techniques were used to characterize the structure of microspheres. The average size of the microspheres was estimated around 50...

Role of negative dielectric and optical quantum dot waveguiding methods in communication

While the application of optical and photonic technologies in the communications, computing, medicine and industrial manufacturing has been growing rapidly, the miniaturization of these technologies has been slow due to the limitation on the diffraction. However, the developments of nanoscale components and guiding methods are continuing with a rapid pace. Since waveguiding is a fundamental iss...

A Proposal for a New Method of Modeling of the Quantum Dot Semiconductor Optical Amplifiers

With the advancement of nanoscale semiconductor technology,semiconductor optical amplifiers are used to amplify and process all-optical signals. Inthis paper, with the aim of calculating the gain of quantum dot semiconductor opticalamplifier (QD-SOA), two groups of rate equations and the optical signal propagatingequation are used in the active layer of the device. For t...
