Styrene-acrylate copolymer was synthesized in presence of carbon black through heterogeneous polymerization. The percentage of monomer conversion was measured by gravimetric method, also PSA, SEM, DSC and GPC were used for studying the particle size and particle size distribution, morphology, thermal properties and molecular weight, respectively. As well as color properties were characterized b...

The design and method for the production of an all-polymer microfluidic particle sorter, for use in biomedical applications, is described. The sorter is made from biocompatible materials with properties, such as high optical transparency, that make it useful in a biological laboratory. The method of sorting is designed to be gentle on biological species, using a method of guiding the particles ...

The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...

This paper discusses about preparation of biodegradable polymer /clay nanocomposites based on organically modified montmorillonite clay; i.e. cloisite 10A and biodegradable polymer chitosan by solution mixing technique and their characterization. The nanocomposites were successfully prepared and their structures were characterized by powder x-ray diffraction (XRD), particle size analyzer (Beckm...

in this study, al/al2o3 composites with two different particle sizes of 1 µm and 0.3 µm were produced via accumulative roll bonding (arb). the microstructure evolution, mechanical properties and fracture behavior of the composites were investigated. results show that higher arb cycles are required to achieve a uniform distribution of particles in the composite with 0.3 µm particle size. during ...
