Abstract Silver nanoparticle is useful metallic due to plasmonic property. One of the most important application silver enhancing Raman spectrum using so-called surface-enhanced spectroscopy (SERS). Mostly, researchers synthesize colloidal nanoparticles and deposite on substrate form SERS substrates. In this work, we simplified synthesis by use microwave. We have successfully grown unpolished s...

The kaolinite of the Duikhala Deposite in Iraqi Western Desert underwent intercalation with potassium acetate (KAc) and was subsequently washing water several times. More than 70% achieved checked using X-ray diffraction (XRD) technique by observing a decrease peak intensity 7.2 Å appearance at 14 after two days intercalation. surface area cation exchange capacity were increased treated sample ...
