Manipulation of Light in Nanoworld: Nanoplasmonics
Contributed by Maxim Sukharev on 25-OCT-07
Author(s) Joseph Yelk, Tamar Seideman

We present basic concepts of plasmon resonance phenomenon and nanoplasmonics for classrooms. Several interactive tools are developed using highly paralleled home-built FORTRAN90 codes to provide physical understanding of plasmonic physics at the nanoscale....

Manipluation of Light in the Nanoworld
Contributed by Boyang Liu on 18-MAY-07
Author(s) Ki Young Kim, David E. Ashkenaz, Seng-Tioing Ho, Jim Chen, Yeh Fei

The nanotech industry is rapidly expanding its territory of influence in the 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 everyday applications, close gap between cutting-edge research and Science, T...

Interactive educational materials for teaching Nanoconcepts
Contributed by Limay Goh on 18-MAY-07
Author(s) Limay Goh, Jorge Pazmino, Effendi Rusli, John A. Washington, Seyeong Im, Valerie Maynard

This poster presents several interactive visualizations and design projects that were developed to teach high school and college students about nanoscience. One of the interactive visualizations investigates how surface-area-to-volume ratio (SA/V) changes as cube size changes. Another interactive visualization explores how successive addition of a chemical to gold nanoparticles in solution results in changes in the color of the solution by changing the size of the gold nanoparticles. The other v...

Interactive educational materials for teaching 'Nano' concepts
Contributed by Limay Goh on 19-FEB-07
Author(s) Limay Goh, Jorge Pazmino, Effendi Rusli, John A. Washington, Seyeong Im, Valerie Maynard, David Bergandine, Terry Koker, Dan Reid, Ramez Elgammel

This presentation discusses interactive educational tools developed for teaching high school and college students about the chemistry of metal, semiconductor, and polymer nanoparticles. One interactive visualization investigates how surface-area-to-volume ratio (SA/V) changes as cube size changes. Another interactive visualization explores how successive addition of a chemical to gold nanoparticles in solution results in changes in the color of the solution, by changing the size of the gold nano...

Computer Animations for Instruction on Nanomaterials
Contributed by Effendi Rusli on 06-SEP-06
Author(s)

Three interactive computer animations and simulations were developed in Macromedia Flash to enhance student learning of nanoscience and engineering concepts through visualization. The first module teaches the impact of surface area/volume (SA/V) ratio on the rate of water absorption for super-absorbent polymers. The second module teaches how semiconductor nanoparticles can be used to degrade organic chemicals in TiO2 photocatalysis. The third module teaches manufacture of nanostructure through s...

Computer Animations for Instruction on Nanomaterials
Contributed by Limay Goh on 04-MAY-06
Author(s) Richard D. Braatz

Two interactive computer animations are described which were made to teach nanoscience/engineering concepts to high school and college students: (1) The "Cube Building" animation teaches the importance of surface area to volume (SA/V) ratio for nanoscale materials. (2) The "Gold Nanoparticles" animation teaches the difference in properties of bulk and nano-sized material using gold nanoparticles....

MAGNETISM AND INFORMATION STORAGE
Contributed by Kirill Rivkin on 30-APR-06
Author(s) John B. Ketterson

We present a short status report concerning our project. In it we outline the progress we achieved during the past half a year. We also outline the main characteristics of our project and its implications....

Manipulation of Light in the Nano World
Contributed by Boyang Liu on 28-APR-06
Author(s)

Nanotechnology has become globally popular. However, it is surrounded by a state of confusion, because it is different from other tangible technologies, and it lacks educational effort to promote the correct image to society. One effective way to close gap between cutting-edge nanotechnology research and education is to use interactive computer simulating and modeling learning programs.Here we showed 2 simulations on Double Slits with interactive user interface and Photonic Band Gap Material. ...

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. ...
