The micro-laminated (ZrO2–Y2O3)/(Al2O3–Y2O3) composite coatings were prepared on the surface of Fe–25Cr alloy by an electrochemical process and a sintering process alternately. FE-SEM analyses show that the cross section of the micro-laminated coatings has alternate six-layer films of...

TiCl4/MgCl2, TiCl4/MgCl2/donor catalysts and TiCl4/donor complexes were prepared in this experiment; the donors are EB, DNBP, DBPG, DBW, PPDE, and BMMF respectively. Chemical states of Ti on the surface of MgCl2-supported Z–N catalysts were analyzed with X-ray photoelectron spectroscopy (XPS)....

International pressure to revalue China’s currency stems in part from the expectation that rapid economic growth should be associated with an underlying real exchange rate appreciation. This hinges on the Balassa-Samuelson hypothesis, which sees growth as stemming from improvements in traded...

Titanium dioxide doped Fe3+ and La3+ nano-composite films were prepared using the sol–gel method. The photo-catalytic properties were evaluated by photo-degradation of methyl orange in solution. Scanning electron microscope, X-ray diffraction, and energy dispersive spectrometer were used to...

The thick ceramic coatings were prepared on 6061 aluminum alloys by microarc oxidation in a silicate electrolyte. The morphology and phase constituent of the coatings with different thickness were studied by scanning electron microscope, and X-ray diffraction. Scratch and thermal shock tests...

Aircrafts hold the outstanding mastery of the sky in modern wars, however the laser beam weapons can carry out laser attacking to aircrafts. The purpose of the present paper is to research on a new type laser protective material. Polycarbosilanes (PCS)/divinylbenzene mixtures containing ZrO2...

In this paper, we first discuss the space frame of multidimensional dynamic credit evaluation (MDCE) theoretically, and then propose the conception of identical credit status and pseudo-identical credit status. Taking advantage of space conformational analysis and optimization techniques, a...

The present research explores how the power state interacts with comparative references in shaping consumer perceptions of price unfairness. Five experiments found that high-power consumers perceive stronger price unfairness when paying more than other consumers do, whereas low-power consumers...
