Abstract:

The diamond coating can improve the performance and durability of cutting tool. To obtain the structure of nano/micro CVD diamond coating, the finite element analysis of nano/micro composite CVD diamond coating on boronized cemented carbide was carried on using ANSYS. The relationship between nanoand micron diamond layer thickness and coating fall off stress was simulated. The thickness of nanodiamond and the micron diamond layer was suggested for the nano/micro CVD diamond coating on boronized cemented carbide cutting tool.

Abstract:

Binary micro-nano rough morphology or structure shows a significant influence on hydrophobicity and icing-resistivity of the surface of coating materials. The leading cause for the classic Cassie state superhydrophobicity is the high area fraction of micro/nano air mattresses being in direct contact with a measured droplet. In this work, the dependence of static hydrophobicity on weight content of commercial surface-hydrophobicity-modified nano-silica in fluoropolymer based composite coatings has been investigated in detail via detecting static water contact angle (CA). It was found that eleva

Abstract:

Natural bone is a composite mainly made from nano/micro-structure of hydroxyapatite and collagen fibers. For bone regeneration by tissue engineering, it is important to synthesize nano-composites with good biocompatibility, high bioactivity and great bonding property as potentially useful scaffold. In this study, we fabricated chitosan nano-nonwoven scaffold via electrospinning and modified chitosan scaffolds by carboxymethylation (CM). Moreover scaffolds were macerated in SBF (simulated body fluid) to form hydroxyapatite on its surface. Surface morphologies (SEM) showed that nano/micro partic

Abstract In this paper, we succeeded in obtaining a Ni/SiC nano composite coating using conventional electro deposition by adding different amount of SiC nanoparticles to a nickel-watt bath to be co-deposited. The effect of electro deposition conditions was studied by changing the amount of SiC nanoparticles in the nano composite, and the deposition current density which affects on the participation of SiC nanoparticles in the coating. The morphology and mechanical properties of the electrodeposited nano-composite were studied. The wear behavior of the nano-composite coatings was evaluated on

The effect of nano-Cu particles on mechanical bend reliability of micro-joining joint with Sn-3.5Ag lead free solder was studied in this paper. The results show that 0.5% nano-Cu composite lead free solder show significantly better shearing strength and mechanical bend fatigue properties than eutectic Sn-3.5Ag solder paste, 1.0% nano-Cu composites and 1.5% nano-Cu composites. The further analysis shows that adding nano-Cu particles make much effect on intermetallic (IMC) in the interface of micro-joint and the inside of the solder joint.

The focus on high-strength and functional natural fiber-based composite materials is growing as interest in developing eco-friendly plastics and sustainable materials increases. An eco-friendly fibrous composite with excellent mechanical properties was prepared by applying the bamboo-derived nano and microfiber multiscale hybridization phenomenon. As a result, the cellulose nanofibers simultaneously coated the micro-bamboo fiber surface and adhered between them.

Abstract:

Nano and micro satellites, when revolving around the earth, may drift by very small angle from their orbit. But this small angle drift may result in large deviation from their original orbit over a long distance which these satellite covers over a period of time. For the course correction of these satellites, very small thrust is required in specific direction. Normal propulsion system cannot serve this purpose, because the thrust may be too large for these satellites. That’s where the role of micro thrusters becomes important. These are MEMS devices which can produce very small thrust and can
