Surface roughness has been considered as an important influencing factor for cell response. The aim of this study was to find out whether MC3T3-E1 cells, a mouse osteoblast-like cell line, can sense the amplitudes of surface topography of titanium alloy (Ti6Al4V), and if surface-dependent cell morphology would be presented on the substrata with varied roughness. A series of polished samples (Ra...

Silicon with a high theoretical capacity (3,579 mAh/g) is promising anode candidate for lithium-ion batteries. However, commercialization still impeded by low Coulombic efficiency, caused solid electrolyte interphase (SEI) formation and trapped lithium (Li)-silicon (Si) alloy during repeated volume change. Quantifying losses from each factor crucial to formulate rational design strategies furth...

An AlGe eutectic wafer level bonding process is presented and characterized for heterogeneous integration of silicon photonics, CMOS integrated electronic circuits and active III-V components. Heterogeneous Integration of Photonics and CMOS The technology of silicon photonics integrated circuits (SiPIC) currently finds itself transitioning from research to industrial scale production [1]. The p...

We report an attempt at increasing the thermal stability of nanocrystalline bainite to tempering heat-treatments, by enhancing the silicon concentration of the alloy. Validation experiments have been conducted using synchrotron X-radiation during tempering heat treatment. It is found that the change in alloying successfully stabilises the austenite at elevated temperatures by retarding cementit...

In order to reduce the impedance and improve in vivo neural recording performance of our developed Michigan type silicon electrodes, rough-surfaced AuPt alloy nanoparticles with nanoporosity were deposited on gold microelectrode sites through electro-co-deposition of Au-Pt-Cu alloy nanoparticles, followed by chemical dealloying Cu. The AuPt alloy nanoparticles modified gold microelectrode sites...

To meet the unprecedented demands for data transmission speed and bandwidth silicon integrated photonics that can generate, modulate, process and detect light signals is being developed. Integrated silicon photonics that can be built using existing CMOS fabrication facilities offers the tantalizing prospect of a scalable and cost-efficient solution to replace electrical interconnects. Silicon, ...

Friction stir welding (FSW) has been widely used in of low melting point metal, such as Al alloy or Cu alloy. However, high Fe alloy, it is difficult to be welded by FSW because short life price tools. Silicon nitride tool can have both long and cost. In order obtain design guideline for silicon tool, the relationship between mechanical properties was examined. Two materials which had different...

Formation mechanism of silicon modified aluminide coating applied on a nickel base super alloy IN-738 LC by pack cementation process was the subject of investigation in this research. Study of the microstructure and compositions of the coating was carried out, using optical and scanning electron microscopes, EDS and X-ray diffraction (XRD) techniques. The results showed that due to low partial ...
