A nanostructural hydroxyapatite (HA) coating was deposited to the porous Ti6Al4V acetabular cup implants using a room temperature electrophoretic deposition (EPD) process in order to achieve the improved bonding strength between the implants and cells, fast healing, good corrosion resistance and long-term stability after implantation. The micropores created in the coating will improve the bioac...

In this work, thin films were deposited on the amorphous glass substrates by magnetron sputtering method. Surface morphology of double-layers of Ag/Al and Ag/Cu were investigated. For surface morphology studies atomic force microscope (AFM) and scanning electron microscopy (SEM) were used, variations of the grain and partical size as well as surface roughness, roughness exponents and correlatio...

Real-time, quantitative measurement of muscle progenitor cell (myoblast) differentiation is an important tool for skeletal muscle research and identification of drugs that support skeletal muscle regeneration. While most quantitative tools rely on sacrificial approach, we developed a double fluorescent tagging approach, which allows for dynamic monitoring of myoblast differentiation through ass...

A volume-surface integral equation (VSIE) formulation is developed for determining the electromagnetic TM scattering by a two-dimensional conducting cylinder coated with an inhomogeneous dielectric/magnetic material. The electric field integral equations (EFIEs) are utilized to derive the VSIE. The surface EFIE is applied to the conducting surface, while the volume EFIE is applied to the coatin...

Abstract: The aim of this bachelor project is to fabricate and study hybrid quantum dot (QD) devices featuring Yu-Shiba-Rosinov (YSR) sub-gap states, made on special InAs nanowires with 7 nm epitaxial aluminum coating on 3 facets. The advantage with these nanowires is the epitaxial aluminum, which can be etched away in a small window of semiconducting nanowire for creating QDs. These dots can b...

This paper compares different coating methods (in situ solid combustion, hybrid deposition, secondary growth on seed, suspension, double deposition of wet impregnation and suspension) to deposit Ce0.2Zr0.8O₂ mixed oxides on cordierite substrates, for use as a three way catalyst. Among them, the double deposition was proven to be the most efficient one. The coated sample shows a BET (Brunauer-Em...

Viscous heating becomes significant in the high speed resin coating process of glass fibers for optical fiber manufacturing. This study focuses on the coating resin flows inside the capillary coating die of optical fiber coating applicator and they are numerically simulated to examine the effects of viscous heating and subsequent temperature increase in coating resin. Resin flows are driven by ...

Buildings that simultaneously provide natural illumination and thermal comfort for all seasons have met with increasing demand as conventional resource limitations are realized. In this context, organic and metal-dielectric coatings are tested, and a simple, coated double-glazed window with solar blinds is conceived that includes passive infrared (IR) reflection, active illumination control, an...

Zinc aluminium (Zn-Al) and lithium (Li-Al) – layered double hydroxides (LDH) coatings with incorporated inhibitors (Li−, Mo− W−based) were successfully synthesized on AZ31 Mg alloy. Zn−Al LDH W Li−Al Li showed the highest corrosion resistance selected for further evaluation. SEM cross−section examination revealed a bi−layer structure composed of an outer part loose flakes denser inner layer. XR...

In this study, an attempt was made to improve the packing density of calcium phosphate (CaP) coating on a magnesium alloy by tailoring the coating solution for enhanced degradation resistance of the alloy for implant applications. An organic solvent, ethanol, was added to the coating solution to decrease the conductivity of the coating solution so that hydrogen bubble formation/bursting reduces...
