| Abstract [eng] |
A new type Rayleigh scattering of Mössbauer radiation (RSMR) spectrometer was developed, which due to favorable time scale of scattering process is suitable for the studies of complicated dynamics of biomolecules (not containing mössbauer nucleus) Densely packed iron nanowire arrays were created using template method of aluminum anodic oxide (AAO). Pore size and density of AAO template can be easily controlled by adjusting anodizing conditions. Shape and diameter of nanowires appear to be exact replicas of AAO pores. the effectiveness of different aqueous electrolytes used in nanowire deposition was investigated. Growth rate in different electrolytes was determined to be 52±2 nm/min. and 11,8±0,6 nm/min. This study has demonstrated the effects of aging of iron nanowires embedded within the pores of the AAO template. the influence of annealing parameters on the chemical composition of iron nanowires was investigated. CEMS studies have revealed. |
