The micro layers micaceous iron oxide and nano-TiO 2 were incorporated into the epoxy resin by mechanical mixing and sonication process. Optical micrographs showed that the number and diameter size of nanoparticle agglomerates were decreased by sonication. The structure and composition of the nanocomposite was determined using transmission electron microscopy which showed the presence of disper...

The Food Stamp Program (FSP) and Supplemental Security Income (SSI) are important parts of national public assistance policy, and there is considerable overlap in the populations that the programs serve. About half of all SSI recipients reside in FSP recipient households. This article uses Social Security administrative data and the Food Stamp Quality Control samples for federal fiscal years 20...

Co-Cr and Co-Cr/nano-TiO2 coatings were electrodeposited from Cr(III) based baths. The effect of TiO2 nano-particles incorporation on the morphology, structure, crystallite size, and preferred orientation was studied. Corrosion behavior of the composite coating was also investigated by means of polarization and electrochemical impedance spectroscopy techniques in Hanks’ si...

Electrochemical impedance spectroscopy and gravimetric methods were carried out to analyze water uptake of thin polyurethane films separately filled with either hydrophobic or hydrophilic nano-silica. Correspondingly the impedance spectra and gravimetric data were interpreted in terms of movement of water within the coating and/or to the coating/metal interface. Although the obtained results fr...

Near infrared spectra combined with partial least squares were proposed as a means of non-contact analysis of the adsorptive ink capacity of recording coating materials in ink jet printing. First, the recording coating materials were prepared based on nano silica pigments. 80 samples of the recording coating materials were selected to develop the calibration of adsorptive ink capacity against i...

Friction stir processing (FSP) has been considered as a novel technique to refine the grain size and homogenize the microstructure of metallic materials. In this study, two-pass FSP was conducted under water to enhance the cooling rate during processing, and an AZ61 magnesium alloy with fine-grained and homogeneous microstructure was prepared through this method. Compared to the as-cast materia...

Hydroxyapatite (HA)ynano-zirconia composite coatings were successfully produced through high velocity oxy-fuel (HVOF) spraying of radio frequency (RF) plasma synthesized powders. Microstructure characterization and morphology analysis on the nano-structured coatings were conducted using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffractometry (XRD), and d...

Consumer and industrial products are manufactured from a range of materials that are selected for specific bulk properties, cost and/or ‘look and feel’. However, many materials chosen in this way do not display the optimum surface properties. This presents an opportunity for surface modifications to apply desirable properties such as fire retardancy, anti-microbial, protein resistance and, wate...

This paper proposes a novel method for hand-gesture recognition based on finger state projection, called FSP Method, which is used to control robotic hands. The control system using FSP Method can simplify the control process of robotic hand considerately while avoiding the drawbacks of traditional hand-gesture recognition methods. The FSP Method measures the projection length of fingers throug...
