Zinc oxide nanoflower (ZnONF) was synthesized by a simple process and was used to construct a highly sensitive electrochemical sensor for the detection of sunset yellow (SY). Due to the large surface area and high accumulation efficiency of ZnONF, the ZnONF-modified carbon paste electrode (ZnONF/CPE) showed a strong enhancement effect on the electrochemical oxidation of SY. The electrochemical ...

Among all non-conventional micro-machining, electrochemical discharge machining (ECDM) is having high quality of material removal rate with zero residual stress. This machining has been accepted as a highly modern technology in micromachining. In this paper an effort has been done on micro drilling of glass using electrochemical discharge machining (ECDM). A fixed tool and a step down transform...

Simultaneous acquisition of in vivo electrophysiological and neurochemical information is essential for understanding how endogenous neurochemicals modulate the dynamics of brain activity. However, up to now such a task has rarely been accomplished due to the major technical challenge of operating two independent recording systems simultaneously in real-time. Here we propose a simpler solution ...

Graphene quantum dots, GQDs, have been synthesized using two strategies: electrochemical (E) and wet chemical (W) methods. A simple, industrially up-scalable, two-electrode electrochemical setup, starting from graphite and a one-pot wet chemical synthesis, modified from reference [1] were used to produce GQDs. Filtration, centrifugation, concentration and dialysis were used to purify the obtain...

We report experimental and numerical results on noise-enhanced synchronization of two coupled chaotic oscillators. Enhanced synchronization is achieved through superimposing small-amplitude Gaussian noise on a common system parameter of the two chaotic oscillators. A resonancelike behavior is found: at an optimum level of noise, maximum synchronization is attained. The simulations show that the...

The chromatographic baseline was converted to power spectrum by Fourier transform to show the frequency dependence of noise. The spectral analysis of chromatographic baseline was made under various experimental conditions for high-performance liquid chromatography with electrochemical detection (HPLC-ECD). From the spectral analysis, it was found easily that a system using a small stroke pump a...
