SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES BY NATURAL ORGANIC COMPOUNDS EXTRACTED FROM EUCALYPTUS LEAVES AND THEIR ROLE IN THE CATALYTIC DEGRADATION OF METHYLENE BLUE DYE

The aim of this work is synthesis of AgNPs from cold and hot extracts of Eucalyptus leaves.After that, microwave irradiation has used to improve properties of these nanoparticles which applied to degrade methylene blue (MB) dye.The change in color of the mixture was from yellow to ruby-brown and to dark brown for the synthesized AgNPs from the cold

This paper introduces an ultra-wideband circularly polarized (CP) asymmetric-S antenna with wide axial ratio beamwidth (ARBW) for Youth Clothing C-band applications.The proposed antenna is realized by bending a linearly polarized dipole into asymmetric-S shape with variable trace width, which achieves CP radiation.Unlike the reported symmetric-S an

Abstract Introduction ACTIVE GREEN TEA The diagnosis and therapy of blunt cerebrovascular injuries has become a focus since improved imaging technology allows adequate description of the injury.Although it represents a rare injury the long-term complications can be fatal but mostly prevented by adequate treatment.Case presentation A 33-year-old Cau
