I keep referring back to these videos for the current project we are working on. This knowledge that you share does volumes to the availability of materials that the poorly funded scientific experimentalist can use. Using some of these videos to produce my own tiny nickel particles, as most scholarly articles you have to pay for information. I can't thank you enough and I hope all is well with you guys across the pond. -Cheers
Sir, hats off to you for sharing this knowledge with world without expecting any thing in return. It’s tiny amount of people like you, which actually make this world a liveable place. God bless
That was BLOODY Amazing! And I can't for the life if me think why anyone hadn't thought of it before. So, what you end up with are copper nanoparticles, right? Wow!
Yep - and what's more it can be adapted to produce nanoparticles of any metal type. it is odd how tings occur to you - this is a combination of current graphene research and green synthesis of metal nanoparticles - so it woldn't occur if you weren't interested in both those things i guess
I'm going to have to watch this video again a few times. Are there any reference books I should check gor this or did you figure it all out originally?
Do a last edit on your videos. add on a thumbs-up sign to remind us to thank you for your time making this vision of an idea placed in the path of future.
@Robert Murray-Smith : Dear Robert, in one of your videos you "applied" copper nano-particles on Inox Silverware by simple "scrubbing". Have you ever checked if this process takes place using nickel nanoparticles in place of copper ones? Thanks, kind regards,
what is the antioxidant you are refering to when after the ascorbic acid u said u added it and then it reduced? is it the green tea you used in the ferro fluid video?
the iron is the reducing agent but the air in the water oxidises the newly formed particles - the ascorbic acid reduces that and acts as a capping agent - so it is both antioxidant and capping agent
I'm interested to make copper nano particles. Would you like to help me? What are the ingredients with thair proportion? Or Can you send detail process for the same? I would like to make new material from this
Hello Sir, I have gone through some of your videos and find them really fascinating. Can this kind of process be used to make mirror like metalized surfaces?
jo atjo really - i am sorry for not replying earlier - i try to reply to all mails and posts - so sorry again - I did this a while ago as a bit of a curiosity and i am afraid I dont' really remember the ratios.
Hi Robert .. how do we seperate the copper nanoparticles from this solution that also has Iron sulphate inorder to use copper nano particles for peen plating using a rock tumblr ?
Hello Robert, great video. So if there are iron nano-particles in dispersed in liquid, does that make the fluid ferro-fluid, or would putting a magnet up to the side of the jar just pull the iron into a clump?
If there is any iron left over you have made a mistake - I actually measured out the stoichiometric amount of iron. The iron will be an impurity and can be removed magnetically
Hi Rob, hope everything is good for you. We are all expected for your news. I am thinking about the solar ink with copper, tin, sulfur and zinc nanoparticles. Your way to make nanoparticles is just amazing. I am wondering myself if can I put zinc copper tin and sulfur at the same in acid ascorbic in order to have a mix of them before to make it a ink. Do you think can I try it or that s better to follow the instructions in your video. Thanks mate for you help
Robert Murray-Smith Hey Robert, My field of interest is lubrication technology. I'm researching a way to synthesize anti-friction agent with a lubricant product as a medium. However, I can't quite get an idea of what catalyst to be used that doesn't acidic (I found salt and sulfide, used as catalyst in most nanosynthesis are too acidic). What idea can you share? Thanks Robert.
Don Koes You could well use this method - the Russians looked into replacement reactions for lubrication back in the 80's so it would be well worth a search of their inventor's certificates - you would need to control particle size of metal you add and use centrifugation of dialysis to remove the remaining sulphate - it's not a finished method so you would have to refine
My only question is are they really nano particles? Most metal powders are made using atomization and people can make lover than 300 µm size particles using atomization technology.
@@user-py9cy1sy9u Kindly post links to the "other videos on the subject" for reference here. He has 1300 or thereabout videos on his channel. Too many to surf through. I have been having trouble understanding some of his audio. The recording is not the clearest ever. The info, however, is intriguing.
