Alumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to its outstanding property characteristics and cost-effective advantage. As with the purity increases, both wear resistance and corrosion resistance also increases, so alumina ar...
The influence of film thickness and molecular weight on the glass transition temperature and coefficient of thermal expansion for polystyrene thin films supported on silicon native oxide surfaces has been studied in detail using variable angle spectroscopic ellipsometry. It was observed that T g exhibits...
Alumina(Aluminum Oxide, Al2O3) is the most extensively used advanced ceramic material due to its outstanding property characteristics and cost-effective advantage. As with the purity increases, both wear resistance and corrosion resistance also increases, so alumina are grouped t...
The model consists of eight components including antireflective coating (ARC) glass, EVA, backsheet (Tedlar), Copper, 60Sn40Pb solder, Silver, Silicon, Aluminum. The dimensions of the constituent components are presented in Table 1, and the mechanical properties of the material in the polycrystall...

(high-impedance reference, highZin Fig.3c) of an echo signal from a polished, thick aluminum block—an approximation of a perfect reflector—was subtracted on the dB/log scale. An example resulting spectra for the three acoustic sensors atT = 37 °C (~310 K) are shown in Fig....
Hence, the exponential permeability model of coal under elastic stage is expressed as:(10)ki=k0e−3Cf(σe−σe0)where k0 is the initial permeability of coal; Cf is the compression coefficient of coal cleat volume; σe is the effective stress; and the σe0 is the initial effective ...
It also has a fair measurement range between 298 K to 453 K with improved sensitivity of 48 pm/°C, and the problem of cross-sensitivity was solved by encapsulating the FBG sensor in an aluminum capillary tube is presented. An etched FBG coated with reduced graphene oxide offers a ...
