Hydrogen free diamond-like carbon (DLC) coatings have been the subject of investigation all around the world for the last 30 years. DLC, due to its unique properties such as: chemical inertness, high mechanical hardness, high electrical resistivity combined with a characteristics of a wide band semiconductor, is a very promising material for biomedical, mechanical and electrical applications. O...

This paper presents the new route of fabrication H-AlSi24Cu3.8Mg0.8 alloy, assisted by ultrasonic vibration stirring and squeeze casting (UVSS). The primary objective this investigation is to establish tribological characteristics prepared aluminium alloy under dry, lubricated, coated sliding conditions. Oil SAE20W40 used as a lubricant diamond-like carbon (DLC) coating. Under load between 20 N...

This paper aims to develop a driver steering model that can capture driver’s key steering mechanisms from a control engineering point of view. Analyses with Double Lane Change (DLC) vehicle test data suggest that, instead of following the traditional concept of trajectory planning, drivers use target points located along the centerline of the lane they are changing to as references for control....

We investigated the long-lasting hydrophilic behavior of a Si-incorporated diamond-like carbon (Si-DLC) film by varying the Si fraction in DLC matrix through oxygen and nitrogen plasma surface treatments. The wetting behavior of the water droplets on the pure DLC and Si-DLC with the nitrogen or oxygen plasma treatment revealed that the Si element in the oxygen-plasma-treated Si-DLC films played...

Segmentation of paraxial mesoderm in vertebrates is regulated by a genetic oscillator that manifests as a series of wavelike or cyclic gene expression domains in the embryo. In zebrafish, this oscillator involves members of the Delta/Notch intercellular signaling pathway, and its down-stream targets, the Her family of transcriptional repressors. Loss of function of any one of the genes of this ...

This study explored the effects of cryogenic treatment on the microstructure, hardness, and wear-resistance of diamond-like carbon (DLC) by cryogenically treating NAK 80 mold steel coated with DLC. Raman spectroscopy analyzed the structure of the DLC film. Nanoindenter analyzed the hardness and Young’s modulus of the film, and their relationship determined the wear resistance. Wear test assesse...

In this study, Ti, Al and N doped DLC – referred to here after as “(Ti,Al)CN/DLC composite”- coating and pure diamond-like coating (DLC) were produced by cathodic arc deposition technique and the effects of the coating thickness on their tribological properties were evaluated. The coatings were characterized, using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffrac...

The primary transport system of sodium and potassium across the plasma cell membrane, the Na/K-ATPase, is a vital enzyme involved in numerous cellular events. This enzyme is the receptor for plant and amphibian steroids such as ouabain, digoxin and bufalin. In the past decade several endogenous steroids, identical or similar to the plant and amphibian steroids, termed here collectively digitali...

Si and N-doped DLC coatings with various Si and N contents were prepared using a magnetron sputter ionplating technology. The antifouling property of DLC coatings was evaluated with Pseudomonas fluorescens which is one of the most common bacteria forming biofilms on the surface of heat exchangers in cooling water systems. The experimental results showed that bacterial removal by a standardised ...
