High-temperature oxidation of silicon-carbide nanoparticles (nSiC) underlies a wide range of technologies from high-power electronic switches for efficient electrical grid and thermal protection of space vehicles to self-healing ceramic nanocomposites. Here, multimillion-atom reactive molecular dynamics simulations validated by ab initio quantum molecular dynamics simulations predict unexpected...

In summary, we have developed a new strategy for the fabrication of arrayed colloidal particles well-ordered nanometric holes of three or four fold symmetry by anisotropic reactive ion (plasma) etching of self-organized layers of colloidal spheres. We demonstrated that a mesoporous silica matrix with regular open windows could be used as a lithographic mask and the resulting arrangement of pore...

1. Introduction A major field of ongoing study in gas mixture separation technology involves the development of novel composite ceramic membranes suitable for use across a broad range of process conditions. A common theme in these studies is the use of mesoporous/microporous support materials (e.g. α-alumina/γ-alumina, Vycor etc) with a minimum pore size of approximately 5 nm, in some cases sup...

Pervaporation removal of methyl tert-butyl ether (MTBE) from dilute aqueous solutions was demonstrated using ceramic-supported polymer (CSP) membranes. These membranes were created by the free radical graft polymerization of vinyl acetate onto a vinyl trimethoxysilaneactivated porous silica substrate having a native average pore size of 500 Å. The resulting membranes consisted of poly(vinyl ace...

The gas separation performance of commercial ceramic Titania and hybrid silica (HybSi®) membranes was assessed using the gas permeation and permporometry methods. Results indicated that the HybSi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. These membranes have high H2 selectivity, which incre...

Abstract Although the initial in vitro dissolution of bioactive glasses (BAG) is well characterized, long-term behaviour crystallized BAG scaffolds a continuous fluid flow incompletely understood. A detailed understanding vital for predicting their clinical applications. Here, we explored and reaction mechanisms partly crystalline glass–ceramic based on S53P4 45S5 using flow-through method Tris...
