16. Studies of Charge Transport and Energy Level in Solar Cells Based on Polymer/Fullerene Bulk Heterojunction
Abstract : π-Conjugated polymers have attracted considerable attention since they are potential candidates for various opto-electronic devices such as solar cells, light emitting iodes, photodiodes, and transistors. Electronic de vices based on conjugated polymers can be easily processed at low temperature using inexpensive technologies. READ MORE

17. Sediment transport from source to sink in the Lake Baikal basin : Impacts of hydroclimatic change and mining
Abstract : Different magnitude, intensity and timing of precipitation can impact runoff, hillslope erosion and transport of sediment along river channels. Human activities, such as dam construction and surface mining can also considerably influence transport of sediment and sediment-bound contaminants. READ MORE

18. Superdiffusive Spin Transport and Ultrafast Magnetization Dynamics : Femtosecond spin transport as the route to ultrafast spintronics
Abstract : The debate over the origin of the ultrafast demagnetization has been intensively active for the past 16 years. Several microscopic mechanisms have been proposed but none has managed so far to provide direct and incontrovertible evidences of their validity. READ MORE

19. Metal accumulation by microorganisms : Characteristics and implications for soil systems
Abstract : The aim of the present study was to investigate the potential role of microbial accumulation in the mobility of metals in soil systems. As a first approach, the metal-accumulating properties of three bacterial species were studied to determine to what extent and under what conditions the accumulation occurred. READ MORE

20. Engineering of metal microstructures : process-microstructure-property relationships for electrodeposits
Abstract : The relationships between growth-conditions, topography and microstructure, and physical properties of electrochemically deposited copper, nickel and zinc-iron alloys were studied. Growth was investigated while systematically varying process parameters such as electrolyte chemistry, type and concentration of additives, current density, and mass transport. READ MORE
