Here, the femtoliter volume of a 3D colloidal assembly is shown, using the evaporation of a fine fountain pen. A nano-fountain pen (NPF) with a micrometer-level tip inner diameter was adopted for the fine evaporation control of the ink solvent. The picoliters of the evapora...

I have to replace the breather tube which was clogged and broke. The clear plastic breather tube material I bought won't fit the hole. I noticed that the old tube appears tapered at the end, to fit the hole. Any solutions? Thanks for your help. Regards, Don...
Changing the barrel finial only really helps if you do not write with the cap posted. It is possible to replace the finial yourself, as I showed in this post:https://www.fountainpennetwork.com/forum/index.php/topic/206822-kaigelu-316-charcoal/?p=2671965. That post also links to Flounder'...

Another confessed, "When I have computer problems and can't get online, I actually panic and am totally miserable until I can once again join my e-mail buddies." Some correspondents were bewildered: one thanked us for "straightening out the frizzies of this e-activity." But not all were...
We demonstrate the three dimensional (3D) growth of multiwalled carbon nanotube (MWNT)–PEDOT:PSS composite microwires by a fountain pen growth (FPG) route. The electrical conductivity of the grown composite wire is improved by enhancing the electrical network of entrapped MWNTs formed in the ...
We report the effective method for producing 3D stretchable conducting polymer interconnects.PEDOT:PSS arched nanowires are successfully fabricated by a fountain pen lithography.The wire's conductivity is enhanced from 2Sm1 to 1.57脳103Sm1 by a steaming co-solvent.It results from a conformational ...
