Among one dimensional nanomaterials, TiO2 nanorods have found important applications in various industries due to optical, photocatalyst and self-cleaning properties. In this research, at first TiO2 nanorods were synthesized on a glass substrate by hydrothermal method. Then a thin film of TiO2 particles was dip coated (as seed layer) on the substrate. After that, hydrothermal synthesis of TiO2 ...

Low-frequency dielectric properties of biological tissues, characterized by αand β-dispersions, are reviewed with emphasis on physical mechanisms. Ion activities, tissue microstructure and composition are discussed. A new mechanism associated with membrane permeability is included. The counterion layer (electrical double layer) phenomenon is discussed. Electrode polarization, which always cause...

The effects of femtosecond laser machining on surface characteristics and subsurface microstructure of a Nitinol alloy were studied. The femtosecond laser machining produced an average surface roughness of 0.2 μm. A re-deposited layer of 7 μm and a hardened layer of 70 μm were also resulted from the machining.

Landforms representative of sedimentary processes and environments that occurred early in martian history have been recognized in Mars Global Surveyor Mars Orbiter Camera and Mars Odyssey Thermal Emission Imaging System images. Evidence of distributary, channelized flow (in particular, flow that lasted long enough to foster meandering) and the resulting deposition of a fan-shaped apron of debri...

BACKGROUND Extracellular deposition of low-density lipoprotein (LDL) in the arterial wall is an essential early step in atherosclerosis. This process preferentially occurs at arterial branch points, reflecting a regional variation in lipoprotein-arterial wall interactions. In this study, we characterized the submicron microstructure of arterial wall collagen and elastin to evaluate its potentia...

The work presents the results of the studies of Co-Cr-Mo casting alloys used in the production of frame casts of removable dentures, crowns and bridges in dental prosthetics. The studies were performed on four Co-Cr-Mo alloys of different contents of Mo, W and other additives. Electrochemical tests were performed, which aimed at examining the corrosion resistance of the alloys and observing the...

Powder bed binder jet printing (BJP) is an additive manufacturing method in which powder is deposited layer-by-layer and selectively joined in each layer with binder. The data presented here relates to the characterization of the as-received feedstock powder, BJP processing parameters, sample preparation and sintering profile ("Effect of solutionizing and aging on the microstructure and mechani...
