The objective of this study is to investigate the effect of solid and liquid lubrication on friction and wear performance of selected solid lubricating coatings  comparative experiments have been carried out on magnetron sputtered MoS2 coatings against Si3N4 ball using a ball-on-disk tribo-tester under the conditions of room temperature and different lubrication. Surface morphology of coatings were investigated by atom force microscope (AFM)  and friction coefficient (COF) and wear rate of solid films were also be analyzed. It was shown that the friction is greatly reduced when the solid film is lubricated with oil and grease simultaneously in comparison with single-lubricant lubrication at the start-up or under boundary lubrication conditions. Liquid lubrication causes a dramatic decrease of the wear-ability of the MoS2 coatings. The effect of oil lubrication to the deterioration of wear resistance of MoS2 film was even worse than lubrication grease. (2013) Trans Tech Publications  Switzerland.

Novel high-boiling liquid/liquid systems were introduced for the synthesis of semiconductor and noble metal  Nanocrystals. polyols and long-chain hydrocarbons were utilized to form such two-phase systems. because  Of the hiah-boiling nature  These systems may be conveniently employed for nanocrystal synthesis at relatively  High temperatures (under the normal pressure) and thus are useful alternatives to toluene/water. cds and ag  Nanocrystals were successfully prepared in an octadecene (ode)/glycerol system via interfacial processes  Demonstrating the effectiveness of this class of two-phase systems. as-prepared nanocrystals had hydrophobic  Surfaces and were dispersed in the ode phase of the system. furthermore  A congeneric two-phase system  Of liquid paraffin/glycerol was also found to be effective for the synthesis of cds and ag nanocrystals.

The Raman scattering of I2 liquid-core optical fiber under the condition of resonance absorption in liquid-core optical fiber is studied in this paper. Iodine is dissolved in transparent benzene to make solution of I2 in benzene  and the absorption coefficients of the solution are measured at certain wavelengths. The absorption curve can be divided into non-resonance absorption region  pre-resonance absorption region  strict resonance absorption region  and post-resonance absorption region respectively. Resonance absorption Raman scattering experiments are conducted by a 532 nm frequency-doubled Nd:YVO4 laser  and the wavelength is in the strict resonance absorption region of solution of I2 in benzene. Compared with I2  the absorption of benzene can be neglected. Non-resonance Raman scattering of the solution is performed using a 632.8 nm He-Ne laser  and no spectrum lines of I2 are found. The study demonstrates that there is one spectrum line of I2 in the Raman scattering spectrum in the I 2 liquid-core optical fiber  but this line is not found in the spectrum of the non-resonance and resonance absorption Raman scattering of I2 solution in benzene using absorption cell. The experiments proved that I 2 Raman scattering  is greatly enhanced by using both resonance absorption and liquid-core optical fiber.

The effects of polymer network formed under UV irradiation with electric field application ( 50V  5Hz) to ferroelectric liquid crystal (FLC) molecules orientation and electrooptic characteristics have been studied. The polymer network formed in SmC*phase is anisotropic and fibrils-like  and a typical striped texture was observed in the cell. The FLC gels exhibit a symmetric V-shaped electrooptic characteristics with thresholdless voltage and high contrast ratio (40:1). A theory explanation of the unique properties is given by establishing a molecular orientation model and conducting a computer simulation. A good fitting of the electrooptic dynamic response of FLC gels has been obtained by introducing a potential (bulk anchoring energy) originated from the photo-cured polymer network. 2002 Taylor Francis.
