16. The Multiple Faces of Interfaces : Electron microscopy analysis of CuInSe2 thin-film solar cells
Abstract : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. READ MORE

17. Cognitive Sensing and Transmission Strategies
Abstract : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates cognitive radios (CR), which identifies vacant spectrum and transmit accordingly. Many algorithms, some as simple as energy detection, are used to sense the spectrum. READ MORE

18. Assessing the Integration of Biomass Gasification-Based Production of Chemicals — Case Study of an Oxo Synthesis Plant
Abstract : The chemical industry sector is energy-intensive and highly dependent on fossil feedstock. The primary long-term option to reduce fossil feedstock dependence and greenhouse gas (GHG) emissions is to switch to renewable feedstock. READ MORE

19. Environmental Assessment of Emerging Bio-based Production - Possibilities in a Future Bio-economy
Abstract : The bio-economy has been put forward as a strategy to increase economic growth without this leading to increased emissions of greenhouse gases. A key concept behind the bio-economy is the increased use of biomass for applications such as the production of bio-based chemicals and materials but also an increased importance for biotechnology and biorefinery systems in the production of these products.

20. Year-round production of forest seedlings under LED lamps : Biological and energetic implications of indoor cultivation
Abstract : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. READ MORE
