Self Organization Map(SOM): If I split dH to dHdo, dHac then HSP vector become 4 dimensions.
That is the very bad news for user. Because the Sphere and GUI can not expand to 4 dimensions.
So we start to develop SOM program to check vector similarity.

Hansen Solubility Parameters (HSP) and graphene:
Congratulation on Nobel Prize!

At the very beginning, graphene was made by sticky tape and graphite.
Now, Dr. Coleman discover solvents with using HSP. He wrote paper, so please refer that paper how to use HSP for this research. Apply Hansen Solubility Parameters (HSP) technology to understand carbon nano materials.

Hansen Solubility Parameters (HSP) of TiO2: Japanese Cosmetic company Shiseido researcher synthesis surface modified-TiO2. And put them to several solvents, and evaluate how stable M-TiO2 in solvents. I re-calculated this result with latest Sphere algorithm, and show it with Sphere Viewer. This procedur is very common to inorganic (Insoluble solubility parameters) such as pigments.

dH divided into donor/acceptor: We add the function to divid dH term into dHdo and dHac terms. We get dHdo, dHac for every compounds (thanks to prof. Abraham) but we just start research to find relationship solubility and dHdo, dHac. The biggest problem is cross term. Donor compounds will interact Acceptor very strongly. So the cross term decrease HSP distance. But how much this cross term decrease HSP distance. We need further research.
