Near-cathode plasma of the discharge in electrolyte and its interaction with electrodes was researched in the work. Electrical parameters of the discharge for two electrolyte compositions were investigated. Temperature and concentration of the near-cathode plasma of this discharge were measured using spectral methods. Appearance of sphere-like formations and pores surface is observed on the surface of the titanium electrodes. Possible explanation of the formation of these superface structures is proposed. The effect of the discharge in the electrolyte on the electrode surface was studied in this work. We consider properties of electrical current near the titanium electrode due to the presence a pores structure on this electrode. We can suppose that the current near the surface of cathode consists from a number of separate current channels with the 0.1-2 μm thick at a current in the region 10-8-10-6 А in the separate channel.

AbstractImmobilized polymerized electroactive vesicles (IPEVs) are submicron biocapsules capable of storing charge in confined environments and chemisorbing on surfaces. Methods to immobilize stable submicron sized electroactive vesicles and the means to measure electroactivity of IPEVs at nanolevels have been demonstrated. IPEVs can withstand steep potential gradients applied across their membrane, maintain their structural integrity against surfaces poised at high/low electrical potentials, retain electroactive material over several days, and reversibly mediate (within the membrane) electron flow between the electrode surface and vesicle interior. IPEVs have strong potential to be used for charge storage and electron coupling applications that operate on the submicron scale and smaller.

Abstract In experiments with short-pulse lasers the measurement control of the energy of the laser pulse is of crucial importance. Generally it is difficult to measure the amplitude of the pulses of short-pulse lasers using electronic devices, their response time being longer than the duration of the laser pulses. The electric response of the detector is still too fast to be directly digitized therefore a peak-hold unit can be used to allow data processing for the computer. In this paper we present a device which measures the energy of UV short (fs) pulses shot-byshot, digitizes and sends the data to the PC across an USB interface. The circuit is based on an analog peak detect and hold unit and the use of fiber optical coupling between the PC and the device provides a significant improvement to eliminate potential ground loops and to reduce conductive and radiated noise as well. The full development is open source and has been made available to download from our web page (http://www.noise.inf.u-szeged.hu/Instruments/PeakHold/).
