The mechanical and electrical characteristics of films, buckypapers and fiber materials from combinations of clay, carbon nanotubes (CNTs) and chitosan are described. The rheological time-dependent characteristics of clay are maintained in clay-carbon nanotube-chitosan composite dispersions. It is demonstrated that the addition of chitosan improves their mechanical characteristics, but decrease...

This work presents a novel and cost-effective procedure that improves the reactivity of kaolinitic clay particles toward generation millimetric hard-core/zeolitized-shell units. The obtained particulate material is ready to use as ion exchanger beads in fixed adsorption bed. Starting from properly activated, millimeter-sized units, transition their external surface towards new crystalline order...

The design of medium- to high-frequency power electronics transformer aims not only minimize the loss in windings and core, but its heat removal features should also allow optimal use both core copper. feature (e.g., thermal conduction) a is complex because there exist multiple centers. bulk total concentrated around small segment assembly where are overlaid. primary winding most constrained th...

During the late Holocene, sediment deposition on the lowland Cosumnes River floodplain, CA has depended on factors that varied temporally and spatially, such as basin subsidence, sea level rise, flow, and sediment supply from both the Sacramento River system and from the Cosumnes River system itself, and anthropogenic changes. Through field investigations and analyses of historical maps, bridge...
