Solid State NMR Characterization of Polymers and Surfactant Molecules as Confined to Porous Silica Mmaterials were prepared in the former case by condensation of silica about micellar aggregations of surfactants ; in the latter case novel polymer nanocomposites were formed by direct polymerization or by absorption of polymers in the pores of the mesostructured silica. The materials provide i

Characterization of Mass Transport and Related Phenomena in Porous Catalysts and Sorbents by NMR Ima can be successfully employed to characterize many of the essential stages of catalyst preparation and use, including multiple coupled processes. The dynamics of Pt or Pd redistribution and the type of their ultimate macroscopic distributions in supported Pt/alumina (Pd/alumina) catalysts can be map

Understanding the heterogeneity of services in international rail transport is essential to meet these needs effectively. Existing research has focused on market segmentation in other transportation sectors, such as passenger transport, airfreight, and maritime transport. Previous research on the gl

H. J. Jakobsen,H. Bildsøe,J. Skibsted,T. Giavaniroduced from renewable energy releases no carbon dioxide emissions during production and use. Therefore, hydrogen is a potential solution for reducing aviation-related emissions. Besides, the economic competitiveness of hydrogen against conventional fuels, mainly influenced by the hydrogen supply ch
