Hi All,

For a some what challenged physics guy I found this history lesson on neutron sources very helpful.

Also I wonder about possible synergies Using quantitative 13C nuclear magnetic resonance (NMR) spectroscopy, when looking at carbon in soils?

Kelly,

You might want to consider correlating what you see with Raman spectroscopy to the materials water holding capacity, as measured by a pressure plate device.   This measurement is the single most important parameter driving plant growth performance with biochar. 

Another rapidly emerging area for biochar is to use it for bio-filtration of storm water runoff.   What is important in this application is Copper, Zinc, and lead sorption.

Subject: [biochar] Graphene Biochar from Proton Power

 
Folks,
Just wanted to put the word out on some very recent and exciting developments at Proton Power.

In order to further characterize of our biochar, a member of our material science team (formerly with Oak Ridge National Labs), was analyzing Raman spectroscopy data and noticed pronounced spikes, suggesting the presence of graphite and graphene.
​  
We learned last Thursday that our proposal was accepted by ORNL to use their Spallation Neutron Source.



I suspect there's probably endless applications for this piece of equipment, but it will enable us to take a closer look at the arrangement of carbon atoms and tell apart the amorphous from the crystalline.  We have used X-ray diffraction to suggest we have graphene in the biochar, but this method only accounts for what’s on the surface.  The SPS will allow us to scan the full volume of the material to find out roughly how much graphite / graphene / amorphous carbon exists.
Please feel free to contact me directly if there's any interest on the aforementioned developments.
Thanks,
​Kelly
