Is graphene powder well soluble in ethanol or water?
No.
no, but i think it will be disperse in DMSO
No. But, the "graphene oxide" can well-dispersed in water.
Can anyone help me to understand the calculations in the attached file?? I want to understand the amount of HAuCl4.4H2O (in mmoles) to obtain 2 wt.% of Au in 2 g of Tetra butyl titanium. Thanks
