The severe surface flaws of brittle materials can be ‘healed’ using coating. Here, we describe an inexpensive and applicable process by which a nanometer-scale polymer coating layer based on styrene butadiene with varied clays and [...]
UV-protective, nanocomposite coatings are made by embedding nanocrystalline zinc oxide particles in a polymer matrix. The benefits accrued by incorporating nanoparticles into a polymer matrix become economically driven when several advantageous properties are obtained simultaneously, [...]

We investigated nano-systems of AlN synthesized by DC arc-plasma-induced melting of aluminum in a nitrogen–argon ambient. Actually, the reaction of molten Al with N2 gas yields on a water-cooled surface a mixture of both nanowires [...]
Amorphous diamond is the only material that can emit electrons in vacuum when applied with an electrical field of only a few volts per micron and such current can increase hundreds or millions times when [...]
Great advancement achieved in quantum dot (QD) growth using Molecular Beam Epitaxy or Metal-Organic Vapor Phase Epitaxy (MOVPE) has made QD-based devices demonstrate superior performances.1 However, QD structures are highly-strained material systems grown under low [...]
The behaviors of various electroplated copper films during CMP are important for removal mechanism and defect generation. This article was to study the characteristics of various copper films during CMP, including impurity effect and current [...]
Deposition of highly (111) oriented conductive layer is required for achieving better electromigration resistance and lower resistivity. Moreover, the amount of void defects decreases as the (111)/(200) ratio increases in CMP process. Hence, we investigated [...]
A novel simple method to fabricate high-density and large-area polymer nanopillars on silicon wafer. This method is versatile and can be applied to pattern a wide variety of polymer thin film materials with various proprieties [...]
The advantages of the combined AFM/STM technique for investigating the dielectric properties of ultrathin MeOx layers with high spatial resolution is shown. Particularly, MO2/Si (M=Hf, Zr) interface evolution upon heat treatments is explored. It is [...]

Nanolithography using the atomic force microscope (AFM) is emerging as a promising tool for nanotechnology . We report our results of AFM- induced nanoscale surface modifications in thin films of the CMR manganite material La0.7Ba0.3MnO3. [...]
Carbon Nanotubes (CNTs) are attracting increasing interest as constituents of composite materials for a wide range of applications. MWNT (multi-walled CNT)-ceramics composites are in the beginning of research. The mechanical properties of MWNTs-SiO2 composites were [...]
Polyamide-6, organically modified montmorillonite, and ethylene/glycidyl methacrylate (E-GMA) and ethylene/butyl acrylate/glycidyl methacrylate (E-BA-GMA) terpolymers acting as impact modifiers for polyamide were melt blended in order to investigate the effects of component concentrations on the final [...]
Nanophase Technologies Corporation has developed new surface treatment technologies for nanoparticles. The new surface treatments may be applied to a wide range of nanoparticle types and chemistries and enable the nanoparticle interface to be tailored [...]
Electrospun fibers have been used in various applications including filtration media, biomedical, ceramics and composites. Electrospinning uses an electric field to draw a polymer solution jet from the tip of a capillary to a collector [...]
Since the late 1990’s, research has been underway in our group at Michigan State University to investigate the production, fabrication and modification of a new nano-sized carbon material, exfoliated graphite nanoplatelets [xGnP]. The xGnP is [...]
Quantum dots (QDs) are colloidal semiconductor nanocrystals that photoluminescence emission is proportional to the dot size and have been utilized in fluorescent imaging in biological systems. Biofilms are communities of microorganisms attached to surfaces encased [...]
This project will utilize SEM and molecular modeling analysis to determine morphological consequences of presonication time on lignin particle size and the joint sonication of lignin with CNT. The investigation will yield a more fundamental [...]
Composite films have been prepared in one step by a vertical deposition method from the aqueous suspension of gold colloids and polystyrene (PS) microspheres. The composite is formed on a glass substrate by convective assembly [...]
Innovative poly(methyl methacrylate) based nanocomposites filled with two kinds of calcium carbonate nanoparticles, coated with stearic acid and poly(butyl acrylate), were prepared. The influence of the nanoparticles nature and content on the chemical-physical properties of [...]
