Microscopes and various forms of interferometers have been used for decades in optical metrology objects that are typically larger than the wavelength light ?. Metrology sub-wavelength objects, however, was deemed impossible due to diffraction limit. We report measurement physical size with deeply accuracy by analyzing pattern coherent scattered deep learning enabled analysis. With a 633 nm las...

The non-oxidative dehydrogenation of methanol to formaldehyde is considered a dream reaction compared with the classical oxidative route, because valuable coupled product hydrogen formed instead water, and produced anhydrous highly suitable for further synthesis oxygenated synthetic fuels. This study reports on high catalytic performance pure β-Ga2O3 in this at temperatures between 500 °C 650 °...

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...

An increased knowledge of the chemistry PuO2 is imperative for design procedures to store, dispose, or make use PuO2.

Determining the switching speed and mechanisms in ferroelectric HfO 2 is essential for applications. Switching dynamics orthorhombic epitaxial Hf 0.5 Zr O films with either significant or negligible presence of monoclinic paraelectric phase characterized. spectroscopy reveals that polarization pure can be modeled by Kolmogorov–Avrami–Ishibashi mechanism large characteristic time (?1 µs), which ...

      Hydroxyapatite (HA) nano-rods with uniform morphology and controllable size have been successfully synthesized in the presence of cationic and non-ionic surfactants by a hydrothermal method. (NH4) 2HPO4 and Ca(NO 3)2.4H2O were used as the phosphorus and calcium sources, respectively. The composition of synthesized powders w...
