NPTEL: Soft Nano Technology

 with  Rabibrata Mukherjee

The fabrication of large area polymer structures with feature sizes ranging from few microns down to the molecular level is key to various technologically important areas, examples of which include molecular electronics, flexible display screens, optical sensors, structural colour, reusable super adhesives, super hydrophobic and self-cleaning surfaces, scaffolds for tissue engineering etc. The meso scale, which ranges from a few nm to few microns, interfaces the molecular and the macroscopic worlds. Thus, it becomes possible to observe simultaneous signatures of molecular interactions as well as macroscopic effects at these length scales, often giving rise to exciting new phenomena. The success of the desired applications, harvesting theextraordinary scientific phenomena occurring at these length scales, dependsstrongly on the availability of suitable, easy to implement patterning techniquesthat can create defect-free structures over large areas followed by their accurate characterization.

In this course we will learn how to create nano patterns on Soft Surfaces, particularly on Polymer films by various techniques. We will start out discussion with certain general concepts related to nano patterning, understand various issues related to Surface Tension and look into some applications of Nano Patterned surfaces (Module 1). Subsequently we will talk about Photolithography (Module 2) and various Soft Lithography techniques (Module 3) that allow crating nano pattern. Finally we will learn the basic working principle and functioning of a very important instrument that is widely utilized in Nanotechnology research: the Atomic Force Microscope (Module 4).

What are MOOCs?
MOOCs stand for Massive Open Online Courses. These are free online courses from universities around the world (eg. Stanford Harvard MIT) offered to anyone with an internet connection.
How do I register?
To register for a course, click on "Go to Class" button on the course page. This will take you to the providers website where you can register for the course.
How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you.  They also have student discussion forums, homework/assignments, and online quizzes or exams.
