To obtain crystalline thin films of alpha-Quartz represents a challenge due to the tendency for material towards spherulitic growth. Thus, understanding mechanisms that give rise growth can help regulate process. Here type 2D crystal in amorphous Quartz was analyzed by electron back-scatter diffraction (EBSD). EBSD used measure size, orientation, and rotation crystallographic grains polycrystal...

Abstract In this study, a toroidal quartz ( $20\overline{2}3$ ) crystal is designed for monochromatic X-ray imaging at 72.3°. The produces excellent images of laser-produced plasma emitting He-like Ti X-rays 4.75 keV. Based on the simulations, resolutions spherical and crystals in sagittal direction are found to be 15 5 μm, respectively. Moreover, simulation results show that higher resolution ...

Abstract Bitumen concrete construction and technical properties improvement when used as refuse finely-fragmented layer inorganic material formed in production of ceramic granite, material, is conditioned by its phase composition structure. The set physicochemical studies has established that the high physical granite are associated with microstructure, which presents glassceramic composite con...

We propose a new method to determine the absolute structure of chiral crystals, which is based on asymmetry multiple scattering diffraction. It manifests as difference in azimuthal dependence forbidden Bragg reflection intensity measured with left and right circularly polarized X-ray beams. Contrary existing ones, suggested does not use anomalous dispersion. The between Renninger scans X-rays h...

The development of ultrasonography would not be possible without the earlier findings concerning ultrasounds. As early as the thirteenth century Lazzarro Spalanzani observed that bats use hearing rather than sight, considering location in space. In 1938, Donald Griffin described the phenomenon of echolocation in these mammals. In 1880, Pierre and Jaques Curie showed the piezoelectric phenomenon...

The alternate adsorption of polycation poly(allylamine hydrochloride)(PAH) and the sodium salt of the polymeric dye poly(1-[ p-(3'-carboxy-4'-hydroxyphenylazo)benzenesulfonamido]-1,2-ethandiyl)(PCBS) on quartz crystals coated with silica was studied to understand the structural properties and adsorption kinetics of these films using a combination of quartz crystal microbalance with dissipation ...

Efficient exfoliation of well-crystallized (Y0.96Tb x Eu0.04-x )2(OH)5NO3 · nH2O (0 ≤ x ≤ 0.04) layered rare-earth hydroxide (LRH) crystals into tens of micron-sized unilamellar nanosheets has been successfully achieved by inserting water insoluble oleate anions (C17H33COO(-)) into the interlayer of the LRH via hydrothermal anion exchange at 120°C, followed by delaminating in toluene. The inter...
