Fabrication and EL measurements of OLEDs.
The evaporating rates were kept at 0.5-1Å s-1 for organic layers and LiF layer, and 10Å s-1 for Al cathode, respectively.
EL spectra were measured with a Hitachi MPF-4 fluorescence spectrophotometer.
EL properties.
The EL spectra centered at 550nm show broad EL emission with the full width of half maximum of 105nm and hypsochromic shift compared with PL spectrum probably due to the solvatochromism [18].

Among three Thermal barrier coating materials, Yttria Stabilized Zirconia showed better mechanical properties such as elongation (EL) of 6.25%, tensile strength TS of 106.06MPa and yield strength (YS) of 90.34MPa when compared with that of the base piston metal Aluminium Alloy (Al Ai).
Prasad and Samira et al [4] used thermally insulating material, namely partially stabilized zirconia (PSZ) on the piston crown face and reported a 19% reduction in heat loss through the piston.
Mechanical properties such as elongation (EL) tensile strength (TS), yield strength (YS) Hardness (H) were investigated.

However, leaf pH did not vary significantly among the geographic populations of El and MP.
Zhao et al. (2007) reported significant phenotypic variations within and between populations of Aquilaria sinensis (Lour.)
Ma et al. (1998) demonstrated that the 6 geographic populations of Poacynum pictum Baill. varied in stomatal types and number of stomata[8].

Physical Simulation of Thermo-Mechanical Processing of Ferritic-Bainitic Dual Phase (FBDP) Steel Taher El-Bitar1, Eman El-Shenawy1,* and Maha El-meligy1 1Plastic Deformation Department, Central Metallurgical R&D Institute (CMRDI), Egypt Keywords: Ferrite, Bainite, Dual Phase, FBDP, high strength steel, automotive industries, Gleeble 3500 Abstract: The present work is dealing with a physical simulation of thermo-mechanical processing of ferritic-bainitic dual phase (FBDP) steel alloy containing 0.1% C, 0.3% Si, 0.9% Mn and 0.7% Cr.
Kumar et al.[5] investigated microstructural characteristics of FBDP steels with 60 to 70% bainite, and found that the steel possessed an excellent combination of strength and ductility.
Recently, Podder et al. [6] reported that a small amount of martensite (2% and above) is sufficient to produce continuous yielding, high tensile strength, and adequate ductility in FBDP steels.

The banks of materials under study are called AGC, El Colegio, El Tigre and Cerritos, which are located in the Morelia Michoacán region, the first two are banks of crushed materials and the second banks of volcanic stone materials.
El procedimiento consiste en marcar la muestra para identificarla, se dejan saturar en el agua durante un periodo de 24 horas, después se procede a secar superficialmente y registrar su peso húmedo (W en gramos).
Posteriormente se llena con agua el picnómetro y se colocan dentro de este la muestra de roca.
Finalmente se obtiene el volumen de agua desalojado (V en cm³) que es medido con una probeta [6].

Tian et al. [12] reported that it is not easy to synthesize bulk Cr2AlC with high purity by hot pressing Cr, Al, and graphite powder mixture since Al, as a starting material, was readily evaporated during hot pressing.
