2012-10-02 15:10:29

Scientists at the U.S. Department of Energy´s (DOE) Ames Laboratory have discovered the underlying order in metallic glasses, which may hold the key to the ability to create new high-tech alloys with specific properties. Glass materials may have a far less randomly arranged structure than formerly thought. Over the years, the ideas of how metallic glasses form have been evolving, from just a random packing, to very small ordered clusters, to realizing that longer range chemical and...

By Oudiani, Asma El Chaabouni, Yassine; Msahli, Slah; Sakli, Faouzi Abstract The crystalline character of Agave americana L. fibers and its relationship with mechanical properties were studied. Comparative investigations between three different types of fiber extraction were made: raw fibers, distilled water extracted fibers and seawater extracted fibers. A wide angle X-ray diffraction technique was used and cellulosic phases in the three samples were identified. A diffractometric analysis...

By Saiah, R Sreekumar, P A; Leblanc, N; Castandet, M; Saiter, J-M ABSTRACT Wheat-flour-based agropolymers are prepared using an extrusion method. The morphology of the native and extruded wheat flours are analyzed by scanning electron micrography (SEM). During plasticization using water (9%, w/w) and glycerol (12.8%, w/w), a change in morphology of native wheat flour occurs. The structure of these materials was investigated by X-ray diffraction (XRD) with special reference to the amount of...
