I am doing research on tin and tin oxide nanoparticles using laser ablation method.I have varied the liquid media from de-ionized water to acetone ,methanol and ethanol.The all the characterization results shows minimum oxide produced in case of ethanol compare to other......I have read somewhere that ethanol particles form a shell around the target material and stop its reaction with oxide....why this not happened in acetone and methanol?? Need your serious help
