Synthesis and Characterization of Ferrite Thin Films Obtained by Soft Chemical Methods

Caruntu D., Caruntu G., Caruntu D., Caruntu G., Ganju D., Advanced Materials Research Institute, US

Highly uniform transition metal ferrite films with controllable thickness and composition can be obtained by finely tuning the reaction conditions through soft chemical synthetic approaches. We report here our initial, successful attempts in developing the [...]

Structure Induced Ion Recognition of Self-Assembled Monolayers on Gold

Jiang Z., Liu S., Gao Z., Institute of Bioengineering and Nanotechnology, SG

The construction and characteristics of self-assembled monolayers(SAMs) anthraquinone-polyether compounds on gold were described. Surprisingly and in contrast to the behavior of the in solution, the SAMs show very high affinity towards alkali metal ions, as [...]

Optical Thin-film Structures for Color Analog, and Digital, Long-term Information Archiving

Wood W.M., Nichols J.E., Kuhara Corporation, US

We have demonstrated the use of selective, reproducible, milling of sub-micron feature sizes by focused ion beam of optical thin film structures made from robust materials for color and B&W, analog and digital image and [...]

Sol-Gel Synthesis and Structural Characterization of Nano-Composite Powder: NiAl2O4:SiO2

Muralidharan P., Prakash I., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Nano-composites are important class of materials because of many of their physical and chemical properties show particle size dependence. Nano-structured metal (Zn, Mg, Ca) aluminate, with spinel structure, dispersed in SiO2 glassy matrix materials are [...]

A Modeling Tool for Contact Probe Tests on Nano-Particle Filled Materials

Tseng K.K., Vanderbilt University, US

With the recent advances in nano-scale science and engineering, materials containing reinforcement with superior mechanical properties can be found in many advanced products. The accurate prediction of the mechanical properties of this class of composite [...]

A Novel Synthesis of Co@Au Nanoparticles and Characterization

Ban Z., O'Connor C.J., University of New Orleans, US

A homogeneous non-aqueous solution reactions method has been developed to prepare gold-coated cobalt (Co@Au) nanoparticles. After the sample was washed with 8% HCl, TGA, XRD, TEM, and magnetic measurements SQUID are utilized to characterize the [...]

Sustainable Nanocomposite Materials from Cellulosic Plastics

Misra M., Park H.M., Mohanty A.K., Drzal L.T., Michigan State University, US

Sustainable 'green' nanocomposites were successfully fabricated from cellulose acetate (CA), triethyl citrate (TEC) plasticizer and organically modified clay. Maleic anhydride grafted cellulose acetate butyrate (MA-g-CAB) was used as a compatibilizer. The effect of compatibilizer proportions [...]

Nanoparticle Composites for Coating Applications

Cayton R.H., Nanophase Technologies Corporation, US

Nanoparticles can be incorporated into polymeric coatings to enable significant improvement in targeted properties, i.e., scratch resistance, UV resistance, conductivity, etc. Commercial processing methods have been developed to surface treat nanoparticles to render compatibility between [...]

Carbon Nanofiber Reinforced Carbon/Polymer Composites

Joshi M., Bhattacharyya A., Indian Institute of Technology, IN

Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The [...]
