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...

The discovery of extracellular electron conduits has spurred new applications in microbial electronics. Except for a limited number exoelectrogens, most microbes are surrounded by insulating membranes that impair transfer. This study focuses on the fabrication conductive polypyrrole (PPy) coating enhancing charge extraction. polymer deposition is characterized and optimized using combination po...

A scaling analysis is performed on the nonlinear susceptibility of the insulating spin glass Col-,Mn,Cl2.2 HzO. We find that Tg= 2.45 K, (5 = 3.30 and 6 = 3.65 in an x = 0.452 mixture, and that Tg= 2.50 K, (5 = 3.20 and 6 = 3.85 in an x = 0.545 mixture. The exponents (5 and 6 are similar to values found for other insulating spin glasses.

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...

poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (pbgha) and poly (lactide-co-glycolide)/ bioactive glass (pbg) nanocomposite coatings with bone. materials and methods: sol-gel derived 58s bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite nanoparticles were used to prepare the coatings. the nanocomposite coatings were characterized by ...

Nickel-titanium-oxide (Ni-Ti-O) nanotube arrays (NTAs) prepared on nearly equiatomic NiTi alloy shall have broad application potential such as for energy storage and biomedicine, but their precise structure control is a great challenge because of the high content of alloying element of Ni, a non-valve metal that cannot form a compact electronic insulating passive layer when anodized. In the pre...

Advanced insulation materials are needed to support future electrodynamic tether missions as well as for other high voltage applications requiring direct exposure to vacuum/space plasma conditions, such as cabling to solar arrays. Some of the desired characteristics of these materials include the ability to resist damage from low-Earth-orbit environments (including atomic oxygen and micrometeor...
