Remarkable properties of layered metal dichalcogenides and their potential applications in various fields have raised intense interest worldwide. We report tens of microns-sized ultrathin single crystal SnS2 flakes grown on amorphous substrates using a simple one-step thermal coevaporation process. X-ray pole figure analysis reveals that a majority of flakes are oriented with the (0001) plane p...
We report the experimental evidence for the formation of multi-quantum dots in a hydrogenated single-layer graphene flake. The existence of multi-quantum dots is supported by the low-temperature measurements on a field effect transistor structure device. The resulting Coulomb blockade diamonds shown in the color scale plot together with the number of Coulomb peaks exhibit the characteristics of...
Flake fractures of the talus are uncommon injuries, usually associated with marked inversion or eversion of’ the foot and ankle, coupled with tearing of the medial [internal laterals or the lateral [fibuiar collateral] ligament or of both ligaments. \Vatson-Jones (1943), relating ninety-seven cases of fracture and fracture-dislocation of the talus and navicular hone in the Royal Air Force in tw...
Orthorhombic black phosphorus (BP) and other layered materials, such as gallium telluride (GaTe) and tin selenide (SnSe), stand out among two-dimensional (2D) materials owing to their anisotropic in-plane structure. This anisotropy adds a new dimension to the properties of 2D materials and stimulates the development of angle-resolved photonics and electronics. However, understanding the effect ...
Slurry ice is a biphasic system consisting of small spherical ice crystals surrounded by seawater at subzero temperature. Its employment was evaluated in the present work as a new chilled storage method for whole European hake (Merluccius merluccius) and compared to traditional flake icing. Different chemical analyses (nucleotide degradation, formaldehyde formation, lipid hydrolysis and oxidati...
Metamaterials and transformation optics play substantial roles in various branches of optical science and engineering by providing schemes to tailor electromagnetic fields into desired spatial patterns. We report a theoretical study showing that by designing and manipulating spatially inhomogeneous, nonuniform conductivity patterns across a flake of graphene, one can have this material as a one...
In this study, nanostructured alumina was synthesized by solution combustion method and its thermoluminescence properties was investigated. X-raydiffraction (XRD) and scanning electron microscopy (SEM) were conducted to investigate the crystal structure, morphology and the particle size of the powders. It was observed that nano structured α-Al2O3 particles with nano flake morphology and thickne...
Porous alumina ceramics with different porosities were prepared via atmospheric pressure sintering using a sacrificial template method powder as the raw material and carbon fiber (CF) graphite pore-forming agents. The effects of contents ratios agents aspect CF on microstructure, mechanical properties, pore size, pore-size distribution porous samples investigated. In addition, surface fractal d...
