Nanostructures in chameleons, damselflies, and peacocks (oh my!)

My favorite rain jacket is bright blue. So bright, in fact, that my first semester chemistry professor was able to point it out in a class of 300 people to explain principles of visible light and color. As it happened, the class benefited from two examples that day, my jacket and my face which turned …

Ep 7. What Do Glaciers Have to Do With Nanoscience?

Sustainable Nano Podcast cover image

Why do glaciers sometimes look blue? Hint: it's not for the same reason we see blue as the color of the sky!

On this episode of the podcast, we have an interview with Dr. Robert Hamers, following up on his recent blog post. Bob is the Director of the Center for Sustainable Nanotechnology, and he tells us about a recent family trip to Alaska that got him wondering about why some glaciers have an amazing blue color.

Nanomaterials Making Their Way into Fireworks

For many people the celebration of the 4th of July is not totally complete without a good aerial fireworks show. A good firework show needs to have two essential components to deliver that thrilling experience most of us love to see—sound and color effects. Nanotechnology could make it possible for these fireworks effects to be …

In which my Mom questions the size of my nanoparticles

I was talking to my mom the other day, about nanoparticles of course, and she said: "Wait a second! Are there different sizes of nanoparticles??  I thought nano was just nano! You know?" Thanks for the question  mom!  🙂 Refresher: nanoparticles are just spherical or nearly-spherical nanomaterials. To answer my mom's question: There are LOTS of different …

Nanoparticles Are All Around Us

You’re looking at an electron micrograph of gold nanoparticles; a snap shot of tiny gold crystals that are 1/10,000th the diameter of a human hair. Nanoparticles just these like may soon transform every aspect of our day to day lives, from the size of our personal electronic devices to the way diagnose and treat cancer; …

“Why all the nano-hype?” or “Do nanoparticles fall in love?”

Today we’ve got some important things to talk about. I’m not talking about the how or why we’re here on this planet, or settling the great cake vs. pie debate (because clearly pie is the correct choice). No, today we’re thinking big thoughts on small things. First things first though. Gone are the days when …
