Connexions is a web-based document creation and management system for education and research materials. There are two parts toConnexions: a Content Commons that contains these materials and the software tools necessary to create, manage, and access thesematerials. A tour of the workings of Connexions and its parts appears on the Connexionsweb page, under the "About" tab.

From its inception, Connexions was designed to allow the collaborative development and free availability of material.Instructors and authors can modify this material for any educational purpose. Connexions offers Free/Open Source softwaretools to help students, instructors, and authors manage these information assets for sharing and advancing knowledge tobenefit the global educational community. All of this is accomplished through the use of the Creative Commons Attribution license .

There are three general categories of Connexions users:

  • Students - who use Connexions to access information on-line, to prepare for their classes.
  • Authors - who enter content into Connexions in document files called modules.
  • Instructors - who build courses, which are documents created by linking related modules together in a specific order.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
