Zr-PILC synthesis Two grams of a montmorillonite rich clay (for instance Bentonite CAS-No-1302-78-9) in 200 mL of water are stirred for a minimum of 2 hours, but preferably overnight. 50 mL of an aqueous 0.1 mol/L Zirconium(IV) oxychloride octahydrate (ZrOCl2·8H2O; CAS-No-13520-92-8) solution are then dropwise added to the clay dispersion (an isobaric dropping funnel can be used) under strong s...

Bleeding is a well described complication of percutaneous extracorporeal membrane oxygenation support (ECMO). In an effort to prevent ongoing percutaneous-cannula blood loss, we tried multiple methods to achieve hemostasis and obtained the best results with QuikClot Combat Gauze (Z-Medica Corp, Wallingford, CT). This product is made of kaolin, white alumina silicate clay, which initiates activa...

The recent recovery processes of electric arc furnace dust (EAFD) include stabilization within materials with potential uses in the construction sector. EAFD by alkaline activation different alumina-silicates, resulting low-cost and environmentally friendly materials. leaching standards European regulations allow evaluating waste products. This work aims to study introduction FA–clay geopolymer...

the kaolinitic clays have been exploited for more than a hundred years, in the western part of the charentes basin, france, and belong to a paleo-deltaic network. the recent deposits are relatively richer in alumina in comparison with the older ones. the genesis of the kaolin deposits of the charentes basin follows simple geological rules, but their detailed geometry has a great complexity, rei...

Mesoporous Ni–alumina catalysts (Ni–alumina-pre and Ni–alumina-post) were synthesized by one-step sol–gel method using micelle complex comprising lauric acid and nickel ion as a template with metal source and using aluminum sec-butoxide as an aluminum source. The Ni–alumina catalysts showed relatively high surface areas (303 m/g for Ni–alumina-pre and 331 m/g for Ni–alumina-post) and narrow por...
