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...

During the last three decades, carbon-based coatings have enjoyed a growing interest in several industrial applications. By tuning the C sp-to-sp bonding ratio and by alloying the carbon with other elements, the researchers have been able to tailor unique physical, mechanical, and tribological properties in order to satisfy an increased technological demand. For instance, the low-friction coeff...

In this work, we have deposited the diamond-like carbon (DLC) coating on tungsten carbide (WC) tool insert using thermal chemical vapor deposition (CVD) method. For growth of DLC coating, sugarcane bagasse was used as a precursor. Raman spectroscopy, field emission scanning electron microscope (FESEM), and X-ray diffraction (XRD) were to confirm presence inserts. The hardness tests also perform...

In electrochemical sensing devices, aimed for acute and chronic in vivo application, the active surface of the sensor is often negligible compared to the overall surface area of the device in contact with the biological host. Consequently, to minimize the perturbation of an implanted sensor on the in vivo environment the chemical composition and surface texturing of the complete device (the act...

Genesis DoS wafers are amorphous, anhydrous, tetrahedrally-coordinated diamond-like carbon (DLC) films on silicon wafers [1, 2]. Using these wafers, excellent analytical results were achieved quickly after the Genesis return for noble gasses using laser ablation [3]. Yet, obtaining precise and accurate analyses by secondary ion mass spectroscopy (SIMS) has been problematic for a decade -even wh...

Two ultrasonic nondestructive evaluation methods have been applied to systematically characterize the mechanical properties of nanostructured physical vapor deposited diamond-like carbon (DLC) ultra-hard coatings. A photoacoustic guided-wave technique is used to generate broadband surface acoustic waves (SAW) on the coating surfaces, and dispersion relations of the SAW for DLC coatings are meas...

The hemocompatibility of plasma-treated, silicon-incorporated, diamond-like carbon (Si-DLC) films was investigated. Si-DLC films with a Si concentration of 2at.% were prepared on Si (100) or Nitinol substrates using a capacitively coupled radiofrequency plasma-assisted chemical vapor deposition method using a mixed gas of benzene (C(6)H(6)) and diluted silane (SiH(4):H(2)=10:90). The Si-DLC fil...

We have developed and tested transparent microelectrode arrays capable of simultaneous amperometric measurement of oxidizable molecules and fluorescence imaging through the electrodes. Surface patterned microelectrodes were fabricated from three different conducting materials: Indium-tin-oxide (ITO), nitrogen-doped diamond-like carbon (DLC) deposited on top of ITO, or very thin (12-17 nm) gold ...

We describe the recent developments on the diamond-like carbon (DLC) over-coated Microstrip Gas Chambers made on drawn glass substrates. MSGC surface coating with thin DLC layer of stable and controlled resistivity was proposed to overcome the limitation of detector operation due to surface charging-up under avalanches. This brings also advantages for the detector manufacturing technology. The ...
