Potential Woody Biomass Supply Chain Scenarios: A Conceptual Study
Part 2: Sustainable Supply ChainsInternational audienceThe interconnectivity among various business entities and physical functions of woody biomass supply chains requires a system-wide perspective. Extant studies largely focus on individual business units or sets of activities. This paper takes a supply chain perspective to gain an understanding of potential woody biomass supply chains. The study draws insights from an extensive review of literature to conceptualize potential woody biomass supply chain scenarios. Three woody biomass supply chain scenarios and associated logistics activities were defined from the analysis of literature content. They are woody biomass sourcing from forest product manufacturers, forest landowners, and biomass pre-processers. Findings suggest that woody biomass as a marketable commodity creates business opportunities for loggers and forest product manufacturers. In moving forward, infrastructure and technological development is vital, encompassing logging capability and transportation and industrial infrastructure
Damage mechanisms of MoN/SiN multilayer optics for next-generation pulsed XUV light sources
We investigated the damage mechanism of MoN/SiN multilayer XUV optics under two extreme conditions: thermal annealing and irradiation with single shot intense XUV pulses from the free-electron laser facility in Hamburg - FLASH. The damage was studied "post-mortem" by means of X-ray diffraction, interference-polarizing optical microscopy, atomic force microscopy, and scanning transmission electron microscopy. Although the timescale of the damage processes and the damage threshold temperatures were different (in the case of annealing it was the dissociation temperature of Mo2N and in the case of XUV irradiation it was the melting temperature of MoN) the main damage mechanism is very similar: molecular dissociation and the formation of N2, leading to bubbles inside the multilayer structure
