The aim of this study was to investigate the role of personality in choosing the color of sport clothing. This research was conducted through a survey and method of data collection was electronically and data collected by a combined questionnaire. The population of this research included all academics at University of Mazandaran that had e-mail. According to Morgan table, 379 of them were considered as a sample by using simple random method. To measure personality, personality questionnaire was used. For evaluating the preferences of color for sport, a picture was placed with 10 different colors (in three parts of neutral, warm and cold color). Data was analyzed by using polynomial logistic regression. Results showed that the role of personality was significant in the level of 0.05 in choosing the color of sport clothing except panties and people who are more experienced and more conscientious, tend to choose more neutral and cold colors than warm colors.

The reduction of laser reflectivity is important as an effective defense to protect people and sensitive equipment. Reducing the reflectivity of surfaces is the most important strategy for decreasing the damages of laser radiation. In this research, the porous pigments are prepared to achieve the lowest percentage of reflection which were used to fabricate antireflective coatings for laser radiation. The porous carbon pigments containing CMK-1 and CMK-3 were prepared and the resulting black pigments were characterized using XRD, FE-SEM and DR-UV-Vis-NIR. The prepared paints were applied on aluminum substrate and the general tests of paints were investigated. The laser reflectivity was evaluated at wavelength of 532 nm that shows these coatings are effective antireflective coating for laser beam.

Regarding the commercial importance and industrial application of white products, investigation into the performance of whiteness indices and their conformity to the visual assessments is essential. In this paper, the performance of Uchida whiteness index for the evaluation of fluorescent whitening agents (FWAs) treated white specimens is investigated based on the modified CIE tinting formula. In this way, the percentage of whiteness acceptance of the fluorescent white samples with different whiteness and tinting attributes, are achieved based on the observers visual assessments. Besides, the correlations between CIE and Uchida whiteness indices as well as with the results of visual assessments are calculated. The results show that while the performance of Uchida whiteness index has been improved by modifying CIE tinting formula, the CIE whiteness index access white specimens, better. It means that, in the modified tinting region the results of visual assessments conform to CIE whiteness index better than Uchida formula. Moreover, it seems that the results of the Uchida whiteness formula closes to those achieved from CIE whiteness index in the modified tinting region.

The aim of this Research is assessment of surface treatment effect with mercapto silane on nano silica (OX50) on mechanical and heat properties of pressure sensitive adhesive. In this study, at first, the surface of nano silica were treated by mercapto silane through sol-gel method. To studying silanization and functional group of nano particles, using TGA, FTIR analysis. Also, to investigating of chemical and physical interaction of treated and untreated particles with polymeric matrix, softening point, adhesion and lab shear tests were performed. Results revealed that the mechanical and thermal properties of pressure sensitive increased with silica treated.

In this study, dyeing kinetics of the poly(ethylene terephthalate) (PET) interlaced bi-shrinkage and normal textured yarns were considered. The dyeing processes were carried out using C.I. Disperse Blue 183 at different times and temperatures. The experimental data were adjusted to well-known dyeing kinetic equations, i.e. Vickerstaff, Patterson, McGregor and Cegarra-Puente to determine the constant rate of dyeing and diffusion coefficient at different temperatures. The results showed that the exhaustion, constants rate of dyeing and diffusion coefficients were increased with increasing the time and temperature of dyeing process for both normal and interlaced bi-shrinkage PET yarns. Also in all similar dyeing times and temperatures, the exhaustion values and diffusion coefficients of interlaced bi-shrinkage PET yarns are higher comparing to normal PET yarns. The turning point of the exhaustion curve for the BSY PET yarn significantly was decreased (-50%) with increasing the dyeing temperature from 120 oC to 130 oC. Also activation energy of conventional PET yarn was observed 22.3% more than BSY PET yarn. The best adjustments of the both normal and interlaced bi-shrinkage PET yarns with applied dyeing kinetic equations were observed for the Vickerstaff equation.

In this investigation, a polyester-amide hyperbranched polymer possessing 10 hydroxyl end-groups was modified by 3-mercaptopropyle tri-methoxy silane through the well-known sol-gel chemistry. The modification process was carried out using two different independent variables, i.e. pH and duration of the reactions, at two and 4 various levels, respectively. The formers levels were 4.5 and 7 and the latters levels were 0.5, 2, 8 and 24 hrs. To characterize the obtained products, Fourier transform infrared (FTIR) spectroscopy, Nuclear Magnetic Resonance (NMR) and Thermo-gravimetric analysis (TGA) were exploited. The outcomes demonstrated that the replacement of hydroxyl end-groups by mercapto functionalities had already happened. The samples at neutral pH, due to lower speed of hydrolysis reactions and higher speed of condensation ones, showed higher conversions. Among the assessed samples, the one at neutral pH and 8 hours of reaction duration, owed the maximum efficacy. Also, it was concluded that the longer the reaction duration, the higher the modification progress is obtained at both pH levels. Eventually, the optimum conditions for various kinds of modification levels are proposed.

Luster decoration is a thin layer of copper and/or silver nanocrystals dispersed within the glassy matrix. Color and shine of luster decorations depend on absorption and reflection of light. The sizes of metallic nanoparticles have an important effect on interaction of light and these particles. The quality of the thing is seen is related to amount of absorption and reflection light. In this paper different luster raw paints are applied over a tin-opacified glaze and then the samples was fired under suitable oxidation and reduction atmosphere. The sizes of formed nanoparticles in lusters with different color and shine were investigated. Scanning Electron Microscopy-Energy Dispersive Spectrometry (SEM-EDS) and Field Emission Scanning Electron Microscopy (FE-SEM) was used to quantitative analysis and determination of nanoparticle sizes. Experiments showed that color and average size of metallic nanoparticles depend on luster raw paints and the presence of copper in raw paint reduces the size of nanoparticles.
