This paper describes a distributed mechanistic dynamic model of a hydrogen membrane reformer unit (HMR) used for methane steam reforming. The model is based on a square channel monolith structure concept, where air flows adjacent to a mix of natural gas and water distributed in a chess pattern of...
Numerical simulation is a powerful tool in rock engineering planning and design, particularly when difficulties and uncertainties are expected in underground excavation. For tunneling through major weakness zones or faults where the geometry is complex, three-dimensional programs have been widely...
Microbial life in extreme environments is attracting broad scientific interest. Knowledge about it helps in defining the boundaries for life to exist, and organisms living under extreme conditions are also interesting sources for enzymes with unusual and desirable properties. The tremendous progress...
Alginates from seaweed are used in chronic wound management, though the molecular and cellular effects of various alginate dressings are not well documented. We have developed ultrapure sodium-alginates from Pseudomonas fluorescens with different content and distribution of single guluronic acid (G...
In order to realize reliable 3D stacking of micro electromechanical systems (MEMS), interconnection and through wafer via technologies have been adapted from other areas and verified for MEMS applications. True stacking of a system including MEMS requires vias through the MEMS and electrical and...
This work was an investigation of the effect of nanoparticles on the durability of wood specimens exposed to artificial weathering. TiO2 and clay nanoparticles were mixed with preservative (Wolmanit CX-8) for improving the durability of Norway spruce (Picea abies). Impregnated and untreated...
In post combustion CO2capture, the large scale use of solvents could lead to environmental effects through the emission of chemicals. Finding solvents which have low or no negative environmental effect and determining acceptable emission levels is important for implementing the technology globally...
