Learning Nanotechnology by Haptic Interface
Contributed by Hyung-Seok Hahm on 26-OCT-07
Author(s) Mahsa Kamali, Umberto Ravaioli

We developed a simulation module for Scanning Tunneling Microscopy which utilizes haptic interface. The motivation is that interaction via haptic interface stimulates active learning. As witnessed by the recent success of Nintendo Wii, haptic interface appeals to young generations and is becoming a commodity. We adapted the richness of multimedia and haptic interface that can be potentially leveraged for nanotechnology education. ...

Manipulation of Light in the Nanoworld
Contributed by Boyang Liu on 26-OCT-07
Author(s) Seng-Tiong Ho, Ki Young Kim

Nanotechnology has become a globally popular and also a household name. The nanotech industry is rapidly expanding its territory of influence within last five years. However, it is surrounded by a state of confusion, because it is different from other tangible technologies of the past, and it lacks educational effort to promote the correct image to society. Therefore, more attentions and efforts should be paid on the Nanoscale Science and Engineering(NSE) education to link nano concepts to ever...

Optical Assembly of Micro and Nano Particles with Optical Tweezers
Contributed by Weiqiang Mu on 26-OCT-07
Author(s) Lan Luan, John Ketterson

Optical tweezers provide a powerful tool to manipulate microsize or nanosize particles. We made an interferece optical tweezers setup to trap many particles in the intensity maxima to form a lattice. And at the same time, we introduced a "helper" beam, which can be used to manipulate a single paritcle. We made different kinds of optical assemblied colloidal lattices based on our setup....

Practical Problem-Solving through Design Projects
Contributed by Limay Goh on 23-OCT-07
Author(s) D. Reid, V. Maynard, M. Fujiwara, U. Ravaioli, R.D. Braatz

The Science Framework for the National Assessment of Educational Progress repeatedly stresses the importance of teaching 'practical problem-solving that involves design, use of materials, and weighing risks in relation to benefits' A student survey indicated that a significant proportion of students strongly hold serious misconceptions about heat transfer. Several nanoconcepts or ?Big Ideas in Nanoscience? as well as student misconceptions are associated with Size and Scale. An approach to train...

Nanotechnology through Multimedia Visualizations and Simulations
Contributed by Limay Goh on 19-FEB-07
Author(s) Hyung-Seok Hahm, Imran Sobh, Yan Li, Slava V. Rotkin, Umberto Ravaioli

We investigate learning opportunities of nanotechnology through richness of multimedia. To this end, 3D simulations, animations and java applets that facilitate visual, haptic, and audio senses are developed. The first program that is developed contains 3D simulations which are designed to help students acquire hands-on experience on how Scanning Tunneling Microscopy (STM) operates. A joystick is adopted to manipulate a tip of STM and build a 3D image by scanning the tip near the surface of the ...

Zinc Oxide Nanowires for Organic Bulk Heterojunction Photovoltaic Cells
Contributed by Shawn Maurer on 02-MAR-06
Author(s) Michael Irwin, Alexander Hains, Tobin Marks, Robert PH Chang

Organic solar cells have the same theoretical maximum efficiency as pn-junction solar cells but their production requires less energy than traditional pn-junction cells but have not acheived the same efficiencies in practice.(1) Using nanostructured transparent conducting oxide materials instead of traditional flat TCOs helps improve the charge collection from the organic active layer. Devices have been made but devices structure problems remains to be solved. ...
