In this study, the internal resistance with the increasing of electrode thickness in a typical nanoporous carbon-based supercapacitor and their corresponding electrochemical performances were designed and investigated in detail. As for the carbon-based double electrode layer electrochemical system, electrochemical experiments greatly support the fact of nonlinear dependence and indicate that th...

a novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm cmos technology. a resistive-capacitive feedback is used to extend the bandwidth of the amplifier. as the structure is inductor less, it is suitable for low cost integrated optical interconnects. in this paper improved particle swarm optimization have applied to determine optimal trans-resistance and noise of propose...

Reduced contact size would permit higher resolution cortical recordings, but the effects of diameter on crucial recording and stimulation properties are poorly understood. Here, the first systematic study of scaling effects on the electrochemical properties of metallic Pt and Au and organic poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) electrodes is presented. PEDOT:PSS exh...

The effect of vanillin on the corrosion behavior of AA6061 Al alloy in 3.5% NaCl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (EN) techniques. Vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. The best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...

D-(+)-Galactose-conjugated single-walled carbon nanotubes (SWCNTs) were synthesized for use as biosensors to detect the cancer marker galectin-3. To investigate the binding of galectin-3 to the d-(+)-galactose-conjugated SWCNTs, an electrochemical biosensor was fabricated by using molybdenum electrodes. The binding affinities of the conjugated SWCNTs to galectin-3 were quantified using electroc...

Commercially pure aluminium is employed in several industrial applications. On some applications, the surface of this material needs to be functionalised. Laser texturing a powerful tool functionalise and alloy surfaces. However, corrosion resistance laser textured can modified, has rarely been investigated literature. Consequently, commercially saltwater was evaluated using electrochemical tec...

The time-dependent corrosion behavior of pure aluminum (Al) in a chloride-containing environment was investigated using various electrochemical and characterization techniques for up to 336 h. Transmission electron microscopic secondary ion mass spectroscopic analysis revealed the continuous dissolution surface film over immersion time. In meantime, increasing passive oxide thickness resulted r...
