Functional additives, particularly extreme pressure and antiwear additives, in formulated oil will compete to adsorb and function in tribological contacts. A low-polarity commercial base oil, poly-α-olefin (PAO), blended with zinc dialkyl dithiophosphates (ZDDP) has been studied. The tribological performance was evaluated using a ball-on-disk test rig under mixed rolling-sliding conditions in t...

Background: Hydatid disease is characterized by long-term growth of hydatid cysts in the human. The glycan antigens have an important role in the immunology of hydatid cyst. In this study immunological reaction of host sera to different glycan antigens of the cyst, has been investigated. Methods: The antibody responses were tested to glycoprotein and glycolipid of the laminated layer (LL), cyst...

Previous experimental work by Gundel and Wawner showed that the matrix alloy has a strong effect on reaction layer growth in Ti alloy/SCS-6 composite systems. A finite difference technique was used to model the reaction layer growth, which predicts the same trends as those exhibited by the experimental data. Matrix alloying elements such as Mo and Cr in metastable R alloys will affect the equil...

The aim of this study was to determine the expression intensity of c-erbB-2 antigen in oral lichen planus and erosive form of oral lichen in 30 patients, and to compare the obtained results with the inflammation intensity i.e. hyperkeratosis. The examination of expression intensity of c-erbB-2 antigen was conducted through immunohistochemical analysis by APAAP method. Obtained reaction of exami...

Pervaporation membrane reactors are ideal candidates to enhance conversion in reversible reactions generating water as a by-product. This equilibrium displacement can be enhanced through close integration of reaction and separation by way of catalytic membranes. In this research, catalytic hollow fibre pervaporation membranes for the close integration of reaction and separation will be develope...

An analysis of the demands of ULSI and GSI technologies shows the necessity of multi-layer devices to reduction of signal transmission delay time. This reduction is realized by using a better conductor metal, such as Cu and a surrounding insulator with low capacity than actually used, such as Dow Cyclotene 3022. In this paper, the results of evaporated and sputtered Cu to Dow Cyclotene 3022 wer...

A mixture of graphene oxide (GO) and TiO2 nanocomposites was reduced photocatalytically by UV-irradiation and applied as interfacial layer between a fluorine doped tin oxide (FTO) layer and a nanocrystalline TiO2 film. Impedance spectra implied a decreased back-transport reaction of electrons. The graphene–TiO2 interfacial layer effectively reduced the contact between I 3 ions in the electrolyt...

We demonstrate a photochemical reaction between graphene and benzoyl peroxide. This reaction introduces spatially localized defects into the graphene basal plane. The reactivity of the single-layer graphene is approximately 14 times higher than that of the double-layer graphene. Our result suggests that photoexcited graphene transfers a hot electron to benzoyl peroxide and induces its decomposi...
