At Connexions, instructors can easily collaborate on OER development in a variety of roles including coauthors, maintainers, workgroup members, suggesters, and users of derived copies. Instructors can update their OER course material and make it available for distribution quickly.

Owl institute

In addition to providing users with connections to OER resources and communities, the OWL Institute Portal to provides the opportunity for users to develop and share their own OER resources. Contact the Owl Institute to receive "creator" or "teacher" access to courses and pages.

Digital universe

The Digital Universe seeks stewards and voluntary consultants to assist in their efforts "to organize the sum total of human knowledge and make it available to everyone."

Le mill

Tour Le Mill to find a variety of open learning materials. Join the Learning Mill community to contribute and share your own learning materials. FAQs describe how to use the site.

More tools

OLCOS, the UK's Open Learning Content Observatory Services project contains a 30 minute tutorial about how to produce OER . This tutorial provides information and practical tasks in creating and modifying open content in open process as well as formats that can be published as open educational resources and tools, that support this process. Wikieducator promotes collaborative authoring and use of OER by providing tools using wiki technologies such as eXe .  The Wikideducator  Content Development Project  is an opportunity for educators to contribute and share their OER. Wikibooks Wikibooks  is a Wikimedia project that started in 2003 with the goal to create a free collection of open-content textbooks that anyone can edit. Since its inception, volunteers have written over 25,000 modules in a multitude of textbooks. If you're an instructor planning on using Wikibooks for a class project, read guidelines for class projects . Take a tour of the Instructional Architect , a service of the National Science Digital Library, to find out how you can use it to find discipline-specific OER, organize and modify those resources into activities for your students, and make those new activities available to a variety of audiences.  ccMixter is a community music site provide opportunities to collaborate with others to re-purpose and mix existing learning materials licensed under Creative Commons. Send2Wiki is a new tool that lets users easily send a copy of a webpage to a wiki for remixing. Wikia are provides free wiki hosting designed expressly for promoting reuse of open content with the MediaWiki software.

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.

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
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
