The growth and interfacial electronic properties of Ag on CeO2(111) thin films have been studied by synchrotron radiation photoemission spectroscopy (SRPES), low energy electron diffraction (LEED), X-ray photoelectron (XPS). Stoichiometric were grown a Ru(0001) substrate. grows as three-dimensional (3D) particles the well-ordered surface at 300 K with number density ∼1 × 1012 particles/cm2. When has high defects, initially populates these defect sites, leading to two-dimensional (2D) island...
The model catalysts of ZrO(2)-supported Au nanoparticles have been prepared by deposition atoms onto the surfaces thin ZrO(2) films with different morphologies. adsorption and thermal stability on investigated using synchrotron radiation photoemission spectroscopy (SRPES) X-ray photoelectron (XPS). were two methods, giving rise to first method utilized wet chemical impregnation synthesize film through procedure spin-coating a zirconium ethoxide (Zr(OC(2)H(5))(4)) precursor SiO(2)/Si(100)...
The growth, electronic properties, and thermal stability of Au nanoparticles on ordered ZrO2(111) thin film surfaces were investigated by low-energy electron diffraction (LEED), X-ray photoelectron spectroscopy (XPS), synchrotron radiation photoemission (SRPES). films grown a Pt(111) substrate. At room temperature, initially grows as 2D islands the up to 0.1 ML, followed 3D growth with number density ∼1.4 × 1012 particles/cm2. binding energy 4f peaks shifts monotonically toward higher...
Abstract This study explored the application of a high-density pulsed electric current (HDPEC) to mitigate strain hardening in cold-rolled A6061 aluminum alloy while examining simultaneous HDPEC with furnace heating reveal contributions thermal and athermal effects. The results showed that significant strain-hardening relief was achieved through treatment, particularly at 300 A/mm² for 260 ms, resulting 23% reduction strength an 86% increase ductility. Microstructural analysis revealed shift...
The optimization of the gas mass transfer route is particularly critical for growth aluminum nitride (AlN) crystals by physical vapor transport method. With influence Steven's flow and natural convection, Al returns to AlN source surface or low-temperature zone at wall crucible deposition, which not only affects subsequent transmission but also polycrystalline deposition layer difficult clean. Therefore, this work investigates shape efficiency analyzes reasons three shapes leading different...
Friction stir welding (FSW) of carbon fiber-reinforced thermoplastic has shown attractive applications in industrial fields. However, the heat input during FSW is hard to control, which leads significant material loss and fiber damage. In this paper, a polyetherimide (CF-PEI) plate joined via thermal-assisted underwater friction (UFSW). The evaluation heat-assisted UFSW joints conducted by studying surface morphology, microstructure weld interface, state distribution fibers, tensile...
AlN crystals have attracted widely attention because of their excellent optoelectronic properties. However, the huge growth difficulty limits large-scale application, main challenge is how to reduce thermal...
We report the electronic structure of interface ultrafilm Fe film with O -terminated ZnO (000-1) polar surface studied by synchrotron radiation photoemission. It was found that grows in a Stranski–Krastanov mode. The turning point growth mode at coverage ~2 Å. At low coverage, about 1 ML (monolayer) iron (ca. 1.5 Å) oxidized terminative oxygen atoms on surface. Analysis valence band and 3 p photoemission spectra indicates below 2 Å only 2+ species could be detected / interface, after...
