Polymer Matrix Nanocomposites and Nanostructured Materials

Nanostructured Thermoelectric Materials: From Superlattices to Nanocomposites

Energy transport in nanostructures differs significantly from macrostructures because of classical and quantum size effects on energy carriers. Experimental results show that the thermal conductivity values of nanostructures such as superlattices are significantly lower than that of their bulk constituent materials. The reduction in thermal conductivity led to a large increase in the thermoelec...

Polymer-Silver Nanocomposites as Antibacterial materials

The antibacterial effect of silver has been used in a variety of commercially available products and medical devices for many years, either in its metallic or salt form. Nowadays, due to the knowledge acquired within the last decade in the field of Nanoscience and Nanotechnology, the use of silver nanoparticles (AgNPs) for medical and sanitary purposes has been thoroughly studied and dramatical...

Matrix Active Micro- and Nanocomposites Based on the Polymer, Semiconductive and Ferropiezoceramic Materials

Mueller matrix ellipsometry studies of nanostructured materials

Materials can be tailored on the nano-scale to show properties that cannot be found in bulk materials. Often these properties reveal themselves when electromagnetic radiation, e.g. light, interacts with the material. Numerous examples of such types of materials are found in nature. There are for example many insects and birds with exoskeletons or feathers that reflect light in special ways. Of ...

Fabrication of Nanostructured Cu matrix Nanocomposites by High Energy Mechanical Milling and Spark Plasma Sintering

Spark plasma sintering (SPS) is a sintering process that is capable of sintering hard worked powders in short times. This technique was used to fabricate bulk Cu and Cu-SiC nanocomposites. Pure Cu and mixed powders of Cu including 4 vol% of SiC nanoparticles were mechanically alloyed for 25 h and sintered at 750˚C under vacuum condition by SPS method. Microstructures of the materials were chara...
