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 ...

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...

Jamun (Syzygium cumini L.) is a fruit rich in anthocyanins, an important group of natural pigments, with color ranging from red to blue, soluble water, highly antioxidant. Despite its great potential for use as dye, application challenge, due the instability these compounds environmental conditions processing and storage commonly used by food industry. Therefore, this study evaluated microencap...

in this research, tribological characteristics of ni-p electroless coating and double-layered ni-p/ni-b electroless coating were studied. for this purpose, ni-p electroless coating with 25 μm thickness was initially applied to the surface of steel ck45 samples; then, a double-layered ni-p/ni-b electroless coating, including inner layer of ni-p with 15 μm thickness and outer layer of ni-b with 1...

Biomimetic calcium phosphate (CaP) coating has been used successfully for protein delivery, but the release of protein from CaP coating is mainly dependent on the limited dissolution of the CaP coating and the passive diffusion of the protein in the CaP coating. In the present work, our aim is to improve the release behavior of protein from CaP coating and make it more controllable. By using bo...

Amorphous magnetic microwires can be suitable for a variety of technological applications due to their excellent softness and giant magnetoimpedance (GMI) effect. Several approaches optimization soft properties GMI effect covered with an insulating, flexible, biocompatible glass coating tunable are overviewed. The high properties, achieved even in as-prepared Co-rich vanishing magnetostriction ...

Al2O3-bonded SiAlON ceramic with self-coating was prepared using aluminum dross and silicon solid waste as starting materials under ambient air conditions. The changes in phase, microstructure, physical properties of the temperature were analyzed formation mechanism phase elucidated. results showed that higher more suitable for preparation ceramics. As increased from 1400 to 1600 °C, main phase...

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...
