Abstract In the present study, high surface area boehmite nanopowder was recovered from aluminum cans waste. The sodium aluminate solution first prepared by dissolving in NaOH and then, H 2 O added to precipitate boehmite. characterized means of X-ray diffraction (XRD), transmission electron microscopy (TEM) N adsorption–desorption techniques. thermal stability sample investigated using thermog...

objective: maintaining the health of oral tissues is a major goal in dentistry. however, limitations in dental materials, instruments, procedures and medications prevent achievement of this goal. advances in nanotechnology have paved the way to approach this goal. this study reviews the advances on nanotechnology in dentistry. review of literatures: in this review study, google scholar, pubmed,...

Graphene-encapsulated nickel nanoclusters are a feasible strategy to inhibit the deactivation of nickel-based catalysts. In this work, graphene-encapsulated catalysts (Ni@C/HZSM-5) were prepared by compression forming process, using pseudo-boehmite, Al2O3, and ZrO2 as binders. The pseudo-boehmite was gradually transformed from amorphous crystalline alumina at high temperatures, which destroyed ...

The present work analyses a set of cylinders manufactured by pressing and fired from 1000 °C to 1270 °C, which are composed pure Al-rich rocks (bauxite) mixtures bauxite with Al–K-rich clays. aim the study is determine mineral textural transformations that take place in firing their influence on physical properties final products order evaluate refractory potential comparing them various commer...
