a blog by the NSF Center for Sustainable Nanotechnology
Earlier this week I heard a quick piece on NPR's Marketplace called "75 years ago, the transistor ignited the fire of modern innovation," about how the transistor was "born" exactly 75 years ago today: December 16, 1947. It reminded me of a blog post written by CSN graduate student Diamond Jones (now Dr. Diamond Jones!) …

Hearing of the fire at Notre Dame de Paris a year ago broke my heart. I have only been there once in my life, but that visit is one of my most cherished memories. Before studying chemistry and joining the Center for Sustainable Nanotechnology, I earned a music education degree, with a major in voice …

Did you know that the worldās first computers filled entire rooms? Now we can carry even more computing power than those early machines in the palm of our hands, thanks to advancements in nano- and transistor technology. Transistors are the components in a computer that control the flow of electricity and therefore allow the computer …

Did you know that 2019 is the International Year of the Periodic Table? We chemists in the Center for Sustainable Nanotechnology are happy to celebrate this all year long! A particularly delicious example of the Periodic Table (image from the Science History Institute) The periodic table as we know it was first published 150 years …

The United States celebrated Independence Day last week, and most people in the US probably managed to see some fireworks. Besides the fireworks, one of my favorite things this time of year is another kind of light showāfireflies! Thereās something almost ethereal about fireflies in a field on a calm summer night. When I was …

Have you ever made lightning in a pickle? I have. It involves putting two iron nails in a pickle and applying 110 volts of electricity. Itās pretty smelly, but it is worth it to see what looks like yellow-orange lightning in the pickle. Whatās going on? The principle of āput in electricity ā get out …

While the word ābacteriaā conjures images of human illness and death for many people, the vast majority of bacteria in the world allow for the healthy functioning of humans and ecosystems. The way they do this ranges from breaking down food in animalsā digestive systems (yes, even ours) to cycling life-giving chemical elements from things …

Seeing small objects is no simple task, but it is an essential one for scientists from fields as diverse as astronomy and nanotechnology.Ā In order to see tiny things, we need to both magnify them and keep their fine details apparent. Which is more important, raw enlarging power or precise detail?To help me explain, I …
