Making ZnO Gans

Nanocoating the Zinc plate 1. Make two holes (3 mm in diameter) in two corners 2. Connect a piece of copper wire in one of the corners 3. Prepare a NaOH solution (caustic soda + boiled hot water) in a sturdy plastic container and allow it to cool completely 4. Completely immerse the zinc plate in the cooled caustic soda solution and place a lid 5. Leave the zinc plate in the NaOH solution for a few hours 6. Take out the zinc plate and hang it over the caustic soda solution at about 10mm distance and place the lid over the plastic box 7. Leave the zinc plate suspended for about 24 hours 8. Repeat steps 4 to 7 several times 9. The zinc sheet will have a dark gray-blue color 10. Wash the nano-coated zinc plate very well under a cold water jet a few times

Note: - Always use latex (or rubber) gloves when handling caustic soda, caustic soda solution and nano-coated plates !!! - Use safety goggles to create and handle the caustic soda !!! http://keshefoundation.org http://cms72.blogspot.co.uk/p/plasmaganses.html 1

Pregatirea placii de zinc nanoacoperite 1. Faceti doua gauri (3 mm diametru) in doua colturi 2. Legati o bucata de sarma de cupru intr-unul din colturi 3. Pregatiti o solutie NaOH (soda caustica + apa fiarta fierbinte) intr-un vas de plastic rezistent si lasati-o sa se raceasca complet 4. Scufundati complet placa de Zinc in solutia de soda caustica racita si puneti un capac 5. Lasati placa de zinc in solutia de NaOH cateva ore 6. Scoateti placa de zinc si agatati-o deasupra solutiei de soda caustica cam la 10mm distanta si puneti capacul peste cutia de plastic 7. Lasati placa de zinc suspendata cca 24 ore 8. Repetati pasii de la 4 la 7 de cateva ori () 9. Palca de zinc va avea o culoare gri-albastru inchis 10. Spalati foarte bine placa de zinc nanoacoperita sub jet de apa rece, de cateva ori

Nota: - Folositi intotdeauna manusi de latex (cauciuc) atunci cand manipulati soda caustica, solutia de soda caustica si placile nanoacoperite !!! - Folositi ochelari de protectie la realizarea si manipularea solutiei de soda caustica !!!
