In any communication system, the received signal will differ from the transmitted signal due to various transmission impairments. For analog signals, these impairments introduce various random modifications that degrade signal quality. For digital signals, bit errors are introduced: A binary 1 is changed into a binary 0 and vice versa. Increase in data rate of a digital transmission system incr...

In this study, photocatalytic degradation of paracetamol (acetaminophen), an analgesic and antipyretic drug, was investigated in using semiconductors under UV-B sunlight irradiation. Semiconductor materials, Bi2O3, ZnO, TiO2, ZrO2, were prepared simple sol-gel, coprecipitation, microwave synthesis methods. These photocatalyts characterized by various spectroscopic other techniques. As a result ...

Degradation of humic substances in water is important due to its adverse effects on the environment and human health. The aim of this study was modeling and investigating the degradation of humic substances in water using immobilized ZnO as a catalyst. ZnO nanoparticles were synthesized through simple coprecipitation (CPT) method and immobilized on glass plates. The immobilized ZnO nanocatalyst...

Copper vanadate nanoparticles were synthesized by a simple coprecipitation method in an aqueous medium and the products were used as adsorbents for eliminating methylene blue (MB) from water. The structure and morphology of the produced nanoparticles were evaluated through X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM) analysis. The results...

This paper deals with a synthesis of new ionising radiation attenuation composite material from Lu2O3 - Bi2O3 nanoparticles structure, that has never been described yet. The describes the preparation nano- and microparticles by three methods: self-combustion synthesis, solid-state method coprecipitation method. Polymer solution was prepared Polyvinyl Butyral. Afterwards, nanofibers were process...
