Cafad Posted March 31, 2017 Author Posted March 31, 2017 There are some great quotes from Dawn of War that I am a fan of. For instance: "An open mind is like a fortress with its gates unbarred and unguarded." And... "Blessed are those with minds too small for doubt."

Not sure you should be drinking that stuff....... Plenty of "flavours" mentioned here - https://www.rit.edu/affiliate/nysp2i/sites/rit.edu.affiliate.nysp2i/files/banerjee_metal_finishing_final.pdf The solution that you use and the concentration is dependant on the properties that you want to enhance in the Graphene - temperature, conductivity, resistance to wear and so forth. Graphene really has the potential to revolutionise many technologies if we can learn to utilise it effectively. I for one am interested in its combined properties to lower resistance and simultaneously provide resistance to corrosion. This is an interesting presentation - http://www.te.com/usa-en/videos/corporate/graphene-webinar-replay.html The trick will be getting Graphene in a DIY applicator that will effectively improve new and existing electrical connections. I am keen to see if the Mad Scientist stuff does that. Edited April 2, 2017 by scumbag

I am keen to see if the Mad Scientist stuff does that. @scumbag Graphene is mentioned in many different ways as a wonderful miracle product. This includes Magico M3 Drivers made out of Graphene. Have you or anyone else tried the Mad scientist Graphene Enhancer or a similar Graphene product to improve the conductivity of the product? If so what was the outcome?

Guest scumbag Posted April 2, 2017 Posted April 2, 2017 (edited) Well like all miracle technologies, the reality might not turn out to be as awesome as we hoped. I do think it will have some amazing applications in areas that we can only dream of. One place that it has fantastic application is in high wear electrical connections such as sliding contracts. A layer of graphene may provide a very durable, low friction, highly conductive interface. I have not tried the Mad Scientist stuff yet. I am seriously playing around with the idea though. I just need to do some research into whether the method of application (a large deposit in an oil based solution) that they use is actually going to be effective or not for the purposes of reducing resistance and guarding against corrosion.

Guest scumbag Posted April 2, 2017 Posted April 2, 2017 (edited) So here's an interesting anecdote about tweaks - not to do with Graphene. My workmate is in no way into audio. He is about my vintage and gave up listening to anything resembling high-end in his teens I believe. In my office I have my Triptych 3 ways which are a very revealing speaker with high quality components and an inert cabinet. Anti-cable 2.1 speaker cables (newer ones), SOTM SMS200 streamer into a PUC2 transport into a Devialet 120. A high resolution system that reveals each any every change in the chain. So I get my work mate to sit in my office chair in the middle of the room which is the best listening position in my office. I'm talking to him about work related stuff (boring) and then whilst I have my back turned to him next to the speaker and say to him. "Listen to this". I had some music playing at a reasonably low volume (we were still able to hold a normal conversation) and then I added one of my Shakti on-line sticks to the anti-cable speaker cable leading to one of the speakers. "What the hell did you just do?" he says. "What do you mean?" I respond, coyly. "The sound from the speaker totally changed. What did you do to it?". I pulled the Shakti stick off (it is attached with velcro) and showed it to him. Baffled looks ensue. "What is that thing?". So I explained what it is meant to be and what it is meant to do, after the little demo. So here we have a non-audiophile (not trained to listen critically) who did not know what I was doing and was not primed in any way as to what to expect hearing a sudden and fairly strong change in the sound. Remember that Shakti have patents on their technology and they have lab reports and dyno-wheel tests (they tested them on the EMU of cars) to show positive effects. That's still never going to be enough for the scoffers though. It all has be explained neatly within their tidy paradigms. If it does not fit into them (and in this case there are measurements to back up the claims but they will still find room to wriggle out of them) then it can't simply be true. So much for Occham's razor and true scientific curiosity............ Edited April 2, 2017 by scumbag
Guest scumbag Posted April 2, 2017 Posted April 2, 2017 (edited) I shot an email off to Mad Scientist and got this speedy response (which was a response to an example of an MSDS that I sent him that showed a certain type of graphene as highly toxic): "Hi MarkWhat they are talking about here is pristine graphene flakes in ethanol (which evaporates), and this does indeed need special handling - basically you don't want to breathe it, or get it in your eyes. I can imagine that the ethanol vapor could have attached graphene particles and it's easy to see how that could be hazardous. If you look at something more like what we use, say https://graphene-supermarket.com/A-12-Graphene-Nanopowder-25-grams.html then that does not have a MSDS. Not because they forgot, but because it's not considered generally hazardous.For example, see this http://www.materialstoday.com/carbon/articles/s1369702112701013/ and there are many other articles you can find.Our Graphene Contact Enhancer is graphene flakes of varying sizes, suspended in an oil-like substance. It won't evaporate so the graphene will stay in suspension. It's not possible to inhale it in such a form. And I would certainly advise not getting it in your eyes (of course that applies to all sorts of things you can find around the house, bleach for example). But apart from that it's not really dangerous. Cheersbob" That takes care of that worry. I might bite the bullet this week and get some. Edited April 2, 2017 by scumbag
Assisi Posted April 2, 2017 Posted April 2, 2017 @scumbag I am intrigued. I will be very interested in the outcome if you order some graphene from the Mad Scientist. John
