The Ag/calcium silicate nanocomposite with core-shell nanostructure has been successfully synthesized using Ag solution, Ca(NO 3 ) 2 ·4H 2 O and Na 2 SiO 3 ·9H 2 O in ethanol/water mixed solvents at room temperature for 48h. Ag solution was previously prepared by microwave-assisted method in ethylene glycol (EG) at 150°C for 10min. The nanocomposites...
Interaction of GaN crystal faces with chemicals is crucial to understand why various nanostructures are formed during the etching process. We have prepared GaN nanostructures by a photo-assisted electroless chemical etching method in solutions containing KOH and K2S2O8. Morphology nanostructure GaN layers grown by molecular beam epitaxy (MBE) and hydride vapor phase epitaxy (HVPE) were studied. For...
