Tar removal from gasification gases is a determinant step to guarantee the operational feasibility of gasification-to-chemicals/energy systems. However, this very complex process requiring catalytic materials proceed under reasonably low temperatures and convert tars into fuel (i.e., CHx). The use Fe-based catalysts for application has been reported before, however, there are still unsolved que...

Using aerogel as radiator and multianode PMTs for photon detection, a proximity focusing Cherenkov ring imaging detector has been constructed and tested in the KEK π2 beam. The aim is to experimentally study the basic parameters such as resolution of the single photon Cherenkov angle and number of detected photons per ring. The resolution obtained is well approximated by estimates of contributi...

A novel multifunctional material has been designed to provide excellent mechanical properties while possessing a high electrochemical surface area suitable for electrochemical energy storage: structural carbon fiber fabrics are embedded in a continuous network of carbon aerogel (CAG) to form a coherent but porous monolith. The CAG-modification process was found to be scalable and to be compatib...

Introduction: Comets preserve some of the most “primitive” material in the solar system. Proto-nebular and/or interstellar organic matter can be identified by anomalous δD and δN values well outside the range of solar values (eg. [1]). Since carbonaceous nanoglobules are often the carriers of anomalous δD and δN in carbonaceous chondrites [2] and interplanetary dust [3], organic globules should...
