The benefits and drawbacks of creating a public lens. How to point users to your Connexions lenses.

Benefits and drawbacks

Making a lens public is like watching (hearing) a singing contest on television. Some performers should be told not to audition. Some lenses are not very useful. When you make lenses public, your reputation (the quality of your work) is out for everyone to evaluate. So the primary drawback to making a lens public is embarrassment.

Lenses that serve a purpose, that is focus the user (or viewer) to see only part of the repository are desireable and are beneficial to users. Lenses focus to what ever content the lens creator desires. They decide how to tag and make comments. Here is a list of some of the concepts involved with focusing a lens:

  • Specific area of study – such as high performance computers or Shakespere.
  • Materials for a specific course – such as British literature. Different than a collection that might be used as a textbook, but more of the concept of reference materials for a course. You the creator of the lens an we assume the instructor of the course, whan to easily point students to a specific protion of the repository contents.
  • Materials produced by an organization
  • Materials reviewed for a professional journal
  • Materials endorsed by a professional group or institution
  • Materials published by a University Press – Rice University Press uses the Connexions repository for its publication efforts.

During the construction phase of a lens, we strongly encourage that the lens be kept private.

Common ways that you can point users your lenses

Via your personal web site

On your personal web site place a link to your lenses.

Links from your web site

Via a learning management system (lms)

If you are using an LMS include a web site link entry to your lenses.

Via an email

Copy and paste the URL to your lens into an email. Your URL is partially established by you when you create the lens.

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.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
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?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
