Electrochemical detection of bubble oscillation

Detection of power oscillation and simultaneous faults using Clark transform

Distance relays are widely used to protect transmission lines. Sometimes, in these lines due to the occurrence of the oscillation of the power, the impedance calculated in the distance relay enters into its functional zones and leads to the cutting off of the lines. This issue can cause global power outages. Accordingly, in this paper, a Clark-based method for detecting the oscillation of power...

Ultrasound for bubble detection

Germonpré P, Papadopoulou V, Hemelryck W, Obeid G, Lafère P, Eckersley RJ, Tang M-X, Balestra C. The use of portable 2D echocardiography and ‘frame-based’ bubble counting as a tool to evaluate diving decompression stress. Diving and Hyperbaric Medicine. 2014 March;44(1):5-13.) Introduction: ‘Decompression stress’ is commonly evaluated by scoring circulating bubble numbers post dive using Dopple...

Electrochemical 'bubble swarm' enhancement of ultrasonic surface cleaning.

An investigation of surface cleaning using a swarm of gas bubbles within an acoustically activated stream is presented. Electrolysis of water at Pt microwires (100 μm diameter) to produce both hydrogen and oxygen bubbles is shown to enhance the extent of ultrasonic surface cleaning in a free flowing water stream containing an electrolyte (0.1 M Na2SO4) and low surfactant concentration (2 mM SDS...

An Electrochemical Sensor Based on Nickel Oxides Nanoparticle/ Graphene Composites for Electrochemical Detection of Epinephrine

The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...
