Article history: Received 28 September 2015 Revised 2 December 2015 Accepted in revised form 11 December 2015 Available online 12 December 2015 A three-layer backward propagation (BP)modelwas used to predict the hardness of Ni–TiNnanocoatings fabricated by pulse electrodeposition. The effect of plating parameters, namely, TiN particle concentration, current density, pulse frequency, and duty ra...
Aortic stiffness, peripheral wave reflection, and aorta-to-peripheral pulse pressure amplification all predict cardiovascular risk. However, the pathophysiological mechanism behind it is unknown. Tonometric pressure waveforms were recorded on the radial, carotid, and femoral arteries in 138 hypertensive patients (age: 56±13 years) to estimate aorta-to-peripheral amplifications, aortic augmentat...
Reverse breakdown in Cu(In,Ga)Se2 (CIGS) solar cells can lead to defect creation and performance degradation. We present pulsed reverse-bias experiments, where we stress CIGS with a short reverse voltage pulse of ten milliseconds detect the electrical thermal response cell. This way, limit duration stress, allowing us study initial stages modules. Our results show that permanent damage develop ...
Collagen is expected to work as a bonding agent of soft and hard tissues to solid materials. In this study, the electrodeposition of collagen to a titanium (Ti) surface under various conditions, i.e., the pH of the collagen solution, potential, and electrodeposition time, was performed to understand the optimal electrodeposition conditions for the immobilization of collagen to Ti. The effects o...
BACKGROUND Biphasic pulses produced by most commercially available TMS machines have a cosine waveform, which makes it difficult to study the interaction between the two phases of stimulation. OBJECTIVE We used a controllable pulse TMS (cTMS) device delivering quasi-rectangular pulse outputs to investigate whether monophasic are more effective than biphasic pulses. METHODS Temporally symmet...
n-Si/Cd and n-Si/Pb Schottky junctions have been prepared by electrodeposition of Cd or Pb from acidic aqueous solutions onto H-terminated and CH3-terminated n-type Si 111 surfaces. For both nondegenerately nand degenerately n+doped H–Si 111 electrodes, Cd and Pb were readily electroplated and oxidatively stripped, consistent with a small barrier height b at the Si/solution and the Si/metal jun...
A mathematical model was developed which evaluates the effect of the applied deposition parameters on the composition of deposited Fe-Ni-Si02 composites. This model assumes that the discharge rates of Fe(OH)+ and Ni(OH)+ are proportional to their respective surface coverage fraction. The inclusion of Si02 with the deposited alloys is considered. Introduction Fe-Ni deposition is classified as an...
Electrodeposition of CuInSe2 (CIS) and CuInAlSe2 (CIAS) from aqueous solution has been systematically investigated by cyclic voltammetery implementing different scan rates. It has been shown that electrodeposited CIS and CIAS have been formed on the substrate through electrochemical-chemical interaction of reduces species on the substrate. From the obtained results, it could be inferred that I...
We have investigated the formation of a platinum thin film from a simple solution of dihydrogen hexachloroplatinate in a low temperature range of 283 to 295 K by a pulse current technique. Despite the low temperature, the platinum thin film observed with a confocal laser scanning microscope does not comprise particle aggregates but dense layer with a small surface roughness that tends to satura...
