Agricultural Pollution in the Chesapeake Bay and What is Being Done About It

A lot is being said these days about pollution in waterways, how to prevent it, and how to clean up pollution that started decades ago. During a summer spent doing scientific research here in Baltimore, I was able to see the effects of pollution on the Chesapeake Bay firsthand. I visited the Inner Harbor in …

Nanotechnology and cars, inside and out

nanotech

Vehicles of the near future will benefit greatly from nanotechnology and nanomaterials. The global expectations for lower emissions and fuel economy are creating huge demands for lightweight, durable, and low-cost materials to replace expensive metals and composites, and nanotechnology can help meet those demands. Nanotechnology1 refers to the production of advanced materials at the scale …

Nano in your ear! Nanotechnology and hearing

stereocilia

Nano in your ear! No, it’s not a childish taunt of nanotechnology adherents or a threat of nano-bots invading our bodies, but a fact of life – nature’s nanotechnology plays a key role in our ability to hear the world around us. To me, “nano in the ear” is not just scientific – it’s personal. Like …

Spring 2018 Update & Recommended Reading

Meet the Scientists demo

It's been a busy month in the Center for Sustainable Nanotechnology! We had our spring all-hands meeting at Johns Hopkins University, where we discussed research, did professional development, and enjoyed some in-person team building. We also got to do an outreach event at the Maryland Science Center, where we had a great time talking with members …

How can graphene nanotechnology improve smart contact lenses?

smart contact

Have you ever wanted to have super-human vision? What would you do if you could record and play back video right in your contact lens? This might sound like science fiction but smart contact lens technology already exists that can do these amazing things and even more, such as medical sensing. (Figure 1). One of …

Engineered Nanoparticles Change Shape in Soil and Groundwater

Engineered nanoparticles (NPs) are now components of thousands of consumer products, including personal care products, sporting goods, solar panels, and next-generation batteries. In fact, demand for electric car batteries (built using lithium-nickel-cobalt nanosheets) might cause lithium prices to skyrocket in the coming decade, and completely change the way in which the element lithium is recovered …

2017: Sustainable Nano Year in Review

Happy 2018! It’s hard to believe, but our very first Sustainable Nano blog post, Why are Nanomaterials So Special and What is the Center for Sustainable Nanotechnology?, was published five years ago, on January 29, 2013! We’ve come a long way – 262 published posts, including 22 episodes of the podcast since its launch in …

Podcast Ep 22. On Thin Films and Nobel Prizes: Margaret Schott Profiles Katharine Burr Blodgett

At last summer's American Chemical Society national meeting, Dr. Margaret Schott of Northwestern University took the unusual step of giving her history division presentation as her subject, Dr. Katharine Burr Blodgett. In this episode we interview Dr. Schott about her own path in life and chemistry, as well as that of Dr. Blodgett, including the …

Celebrating National Nanotechnology Day and Indigenous Peoples Day

gold nanoparticles

When I was a kid, I remember learning that "in 1492, Columbus sailed the ocean blue," and that one Monday in October there was this holiday called Columbus Day that nobody seemed to celebrate except that we got a day off of school. (Turns out it only became a holiday in the 1930s.) Fast forward …
