摘要:

Using the electromigration method in free electrolyte solution for characterisation of the polyiodide equilibrium the influence of isotope exchange on the electromigration behaviour was studied. A special electromigration equation was derived. Based on a theoretical statement electromigration experimental errors were calculated which are in good agreement with the observed errors.

摘要:

2,5-Diphenyl-l,3,4-oxadiazole (PPD) has been investigated for its suitability as a primary szintillator. This compound can be used together with the secondary szintillator POPOP in toluene solution for the measurement of low-energetic β-radiation in biological samples marked by14C. A convenient approach to laboratory syntheses is presented.

摘要:

Electron irradiation of silicon photovoltaic cell causes a pronounced decrease on its output characteristics. On the other hand, short circuit current temperature coefficient is greatly increased with both; radiation fluence and energy, while open circuit voltage temperature coefficient remains fairly unaffected. Shelf annealing of the electron irradiated cell recovers about 50% of its initial output characteristics. Oven annealing was shown to have a significant effect, where heat treatment at 100°C for one hour cause the sample to regain 95% of its initial characteristics.
