LETTER FROM RK SIVAKUMAR TO ME :
 good afternoon ,this method is very easy and cheaf.we prepare nano materials by using

deionised water.we can prepare ag,zr,co,cr,al,zn nano material by this method.

• 3 mg of metal powder was (like Ag ions) added to 30 ml deionized water in a glass veil
• the reaction mixture was sonicated for about 15 min in a glass,transfered in to a stainless steel teflon linked metallic

         bomb of 100 ml capacity and sealed under normal condition

the closed chamber was then placed inside the a preheated box furnace and the mixture was heated slowly
2 c/min to 200 c and maintained the temp for 612 hours.
