Understanding Waveguides: Light at the Nanoscale
13 Feb 2020 | | Contributor(s):: Marilyn Garza, NNCI Nano
There are three lessons for this activity that help students understand how light can travel through a waveguide for communication purposes. Students will first explore the angle of refraction. Next they will create a gelatin waveguide to explore issues associated with light and waveguides....
Quantum Dots: Real-world Particles in a Box
15 Jan 2020 | | Contributor(s):: Joyce Allen, NNCI Nano
The purpose of this activity is to show that nanosize particles of a given substance often exhibit different properties and behavior than macro or micro size particles of the same material. The property studied in this activity is the absorption and reflection of light which is based on energy...
Golden Opportunities: Gold Nanoparticles for Biomedical Applications
14 Jan 2020 | | Contributor(s):: Catherine J. Murphy
In this talk I will discuss how these nanoparticles are prepared, how their surface chemistry can be tuned, how apparent cytotoxicity can be traced back to reagents in the synthesis rather than the particles per se, how protein orientation can be controlled on their surfaces, how cells respond...
CDs and DVDs as Diffraction Gratings
13 Jan 2020 | | Contributor(s):: Rama Balachandran, Karen Porter Davis, NNCI Nano
The objective of this lab is to compare the diffraction behavior of light waves between a CD and DVD. CDs and DVDs contain regularly spaced micrometer sized features which can act like a diffraction grating. Using commercial electronic storage devices like CDs and DVDs as gratings rather than...
Refraction of Light: Forensics Lab
06 Jan 2020 | | Contributor(s):: Karen Porter-Davis, NNCI Nano
This lesson uses forensic science investigations to help students understand the refraction of light. Using The Marching Band Analogy, the students firsts “experience” how wavelengths of light can slow and bend.
Light Extraction by Changing Composition of Material
06 Jan 2020 | | Contributor(s):: Sidhu Rano, NNCI Nano
This activity has been designed to have students explore light emitting diodes (LED) and the importance of index of refraction in improving LED efficiency. This activity investigates the tune-ability of a polymer’s index of refraction by using a macromodel LED.
3 min Research Talk: Plasmonic Core-Multishell Nanowires for Optical Applications
26 Sep 2019 | | Contributor(s):: Raheem Carless
ED lights and technology are being used more often in today’s society. Compared to traditional illumination they are far more reliable and efficient, in the sense that they last longer, are environmentally friendly, and most importantly, they reduce energy waste.

Making a Liquid Crystal Thermometer
09 Jan 2017 | | Contributor(s):: Rano Sidhu, NNCI Nano
Liquid crystals are matter that has properties between those of a liquid and a solid. Liquid crystals may flow like a liquid but have crystals like a solid.colors of the objects are Color is the outcome of various light properties: absorption, refraction, or reflection. In the case of liquid...
Synthesis and Stability of Silver Nanoparticles
01 Dec 2016 | | Contributor(s):: Brandi Childress, NNCI Nano
The purpose of this experiment is to conduct synthesis of silver nanoplates and explore their shape stability that affects optical property (referred to as localized surface plasmon resonance (LSPR). Students will learn about the differences in physical properties and behavior at the...
Uncertainty Measurements and the Wavelength of Light
28 Oct 2016 | | Contributor(s):: Chris Kaus, NNCI Nano
This high school physics lesson is designed to help students understand how very small measurements can be made (even at the nanoscale) and how the accuracy of those measurements affects their results. In this lab, students will calculate the wavelength of a laser (on the nanoscale) using...
