Measuring of Polarization and Ohmic Potentials for the Diagnostics of Corrosion Protection of the Metal Structures

The polarization potential (РР) is regarded as the main criterion of corrosion protection of metal structures in conducting media. However, the potential between the reference electrode and the metal of the protected structure is measured with a voltmeter and contains, in addition to the polarization component, the Ohmic drop of the voltage. But, only the polarization of the surface causes the effect of cathodic protection. Therefore, the Ohmic component should be removed from the measured potential difference for the precise control of the protected structure. To solve the problem of measuring PP is known methods of compensating, relaxation, auxiliary electrodes and calculations, which have disadvantages.

Effect of Infrared Radiation on the Hydrogen in Thin Films Double Barriers Based Melt Silicone-Germany

Abstract Possibilities of plasma chemical deposition of α-Si 1-x Ge x :H (x=0÷1) films undoped and doped with PH 3 or B 2 H 6 have been analyzed from the viewpoint of their application in p-i-n structures of solar cell. The optical properties are considered, and the amount of hydrogen contained in those films is determined. The film properties are found to strongly depend on the film composition and the hydrogenation level. The number of hydrogen atoms in the films is varied by changing the gas mixture composition, and IR absorption in α-Si:H and α-G e :H films is measured. The α-Si:H and а-Si 0,88 Ge 1,2 :H films were used to fabricate three-layer solar with an element area of 1,3 sm 2 and an efficiency (η) of 9.5 %.

The Erroneous Banishment of Plastics Authorized by Walter Eevers Since some months, youth is marching in the streets of several cities throughout Europe. They scream for political attention for the fight against climate change. The debates in the press and on social media go into all directions and give attention to technological solutions to fight climate change, the need for personal lifestyle adaptation but also to fights against nuclear power generation, air traffic etc. But in the margin of these protests also plastics and the use of plastics are condemned in many of these communications.
