The local ordering in amorphous Ga2O3 and (In x Ga1−x )2O3 thin films on Si(111) its change crystallization upon annealing are investigated. Synchrotron-based extended X-ray absorption fine structure data, as probed across the Ga K-edge conjunction with a numerical implementation of scattering process including multiple events, provide detailed insights into bonding character cations. Bond length...

The easiest route to form compounds with P–Csp3–N linkage(s) is phosphorus-based Mannich-type reactions (phospha-Mannich reactions) between phosphines (R3P, R2PH, RPH2, PH3), carbonyl (mainly CH2O) and amines (R2NH, RNH2, NH3). Because of toxicity inflammability, applications PH3 its liquid analog (Me3Si)3P in such are rare. Stable, less toxic, non-pyrophoric adducts CH2O, i.e., tris(hydroxymet...

We propose an adaptive reversible data hiding method with superior visual quality and capacity in which an adaptive generalized difference expansion (AGDE) method is applied to an integer-to-integer subband transform (I2I-ST). I2I-ST performs the reversible subband transform and the AGDE method is a state-of-the-art method of reversible data hiding. The results of experiments we performed objec...

SBA-15 was prepared and then functionalized with N-methyl-N’-propyltrimethoxysilyl imidazolium chloride as ionic liquid moiety. The ionic liquid functionalized SBA-15 (SBA-IL) was characterized by different analytical techniques including FT-IR, N2 adsorption-desorption, TGA and SEM image. According to the obtained results it was found that the organic groups were g...

The pulse density modulation technique has been used in resonant power converters because its ability to maintains soft-switching for any level of output power. The sub harmonics of the switching frequency are in general undesired and are seen as a drawback. In this work are developed analytical equations to express the harmonics and sub harmonics components of a PDM signal. It is still analyze...
