Happy to have recieved my free sample of TUBALL 75wt% Single-walled carbon nanotubes from OCSiAl. I am more than excited to do some purification and experimenting over the weekend as I got a few ideas for hybrid CNT-graphene foams and films up my sleeve.

Take a very deep breath of cleaner air in the US as nitrogen dioxide gas shown to be decreasing in most areas. #EarthRightNow   #NASA  
 
Take a deep breath. You just inhaled less nitrogen dioxide than in 2005. Learn more: http://1.usa.gov/1lPXAzw

Can't wait!!!  Although a tremendous amount of work and research has to be done, it is glad to see NASA is seriously working on interstellar travel using warp drives.

:) Been thinking of making a sonicator myself.  I recently found out that you can buy the 50W piezoelectric transducer replacement online for little over £11. And I have already came up with a simple schematic that will generate the 22.5kHz needed for graphene exfoliation and the parts for that (including 2 power MOSFETs) would cost about the same. I reckon a DIY tip sonicator is much cheaper than the ones they sell for thousands.  And with little modification, you could make a bath sonicator as well, and I am desperately needing one!

no mate that's the energy of the sonicator. The frequency for ultra sound in 20-40Khz, I think, and mine is 40KHz

I have been making my own graphene quantum dots (GQDs) as of late, and have to say they certainly do have some amazing noteworthy properties.

Here is one sample I created and photographed showing the natural appearance and color of the nanoparticle suspension in white light (a), the Tyndall Effect demonstrated using a 532 nm green laser (b), and band bending phenomenon (c), which arises from quantum confinement effects (due to plasmonic resonance). This particular batch illustrates a blue-shift in near-UV light suggesting the sample has a unique band structure similar to antidots, and not like typical GQDs which posses narrow red-shifting that gives rise to photoluminescence (fluorescence).  This particular colloidal nanosuspension is also exhibiting an extremely low water evaporation rate which was not expected.  Minute droplets resist evaporation in an ambient environment remaining totally stable for several days now at RT.

Graphene quantum dots and even graphene antidot lattice arrays can be used for making photovoltaics such as LEDs and solar cells, filters and waveguides for optics, biological markers, novel catalysts for hydrogen generation, and even spintronic-based devices for quantum computers.

On a personal note, I have been making my own nanomaterials for little over a year now, all entirely from my private home lab.  That's what happens when you decide to learn everything you can about chemistry, all the while performing more hands-on experiments to go even further.  I recently enrolled at a 2-year college, and beginning to work towards my first real degree in the field - and am running towards that goal with every fiber in my being.  It goes to show, anyone can do something it if want it bad enough - despite having limited funds or formal education.  So, do not think it is too hard to understand or to do, unless you try, as you will be surprised how easy it just may be to reach your dreams when you have true desire and passion to see it through.

Imagine one day driving around in a electric graphene car, which is made from a graphene composite material and which is powered by, you guessed it, a graphene supercapacitor battery. The Univerisity of Sunderland awarded with new funding from the EU Graphene Flagship to develop enviromentally-friendly, lightweight and durable graphene-based composites for the automotive industry.

Yeah, I did give all the math one would need to figure that out on their own.

+lasersaber +IonPowerGroup Very interesting!  As I understand it, if you lower the voltage, current should increase according to Ohm's Law.  Also, if you use a larger array of capacitors/supercapacitors you will see an increase in current as well.  Very interesting use of graphene/graphite to get a higher surface area for ion collection, etc.  This reminds me of Nikola Tesla pickling his copper plate to get more collected energy.  Thomas Moray's radiant energy device worked along the same premise.  Adding harmonic resonance feedback (tank) circuits will boost output as well when dealing with the Schumann resonance(s).
