=== Barva z aktivniho uhli ===

| 100 g | aktivni uhli |  https://www.habeo.cz/akvaristika/aqua-nova-aktivni-uhli/ |
| 5g | dispercol |
| 50g | destilovana voda|


  * uhli mixovat na sucho 1 min
  * rozredit dispercol ve vode  prilit do uhli


^ uhli ^ doba mixovani ^ dispercol ^ voda ^ rezistivita ^ ^
|100g | 1min |5g | 50g | cca 1-10 MOhm | krehke, hodne hrube |
|20 g | 2 x 1min | cca 0.5g | 15ml |

| 17g | <0.3mm | 1.7g | 15ml vody | dost ridke| 0.5mol Ca2CO3 | velky vnitrni odpor, relativne rychle se samovybiji , zpomali se okolo 0.47V|


uhli mlete v mlynu 15g
1.5 pur lak, spousta s6006 a otira se to a nefunguje


=== Activated carbon out of hemp ===
"How To Make A Hemp Battery - Complete Instructions"
  - take K2CO3,  cca 50% weight of the hemp 
  - leave for 24h
  - dat do plechovky do pece (nebo ohne, kdyz nemam troubu ohne) este mokry

zkusit tlustou bavlnenou latku.. treba dzinovinu vypalit s hydroxidem na aktivni uhli (viz video)


=== Steam activated carbon ===
Making Steam Activated Carbon From Hemp

  - dat do trouby v uzavrene nadobe uhli na cca 400°C cca na hodku
  - na dalsi cca hodoku ohrat na 800stupnu a pustit pres to paru z parniho odlepovace tapet

Hi Rob,
Glad you have the membership section activated.  This has been my preferred method of graphene production for some time now. Didn't think of the nonimpact ball shear. Will try.  If you also add a little thiourea, and under-supply the graphite, you get an unusual multiphase settling of graphene.

grephene like z cuku

cukr, chlorid amonny, utrit dohromady..
 dat do trouby na cca 250? stupnu.. je to ve videu.. akorat tvori se amoniak  a chlorovodik ohrivat pomalu.. cca ctyri stupne za minutu (asi by to chtelo vakuovou susici troubu)

a pak zahrat aby to zuhelnatelo..(asi by mohla stacit plechovka)
