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 … Continue reading

How can you calculate how many atoms are in a nanoparticle?

Two years ago, I wrote a blog post called Two Ways to Make Nanoparticles, describing the difference between top-down and bottom-up methods for making nanoparticles. In the post I commented, “we can estimate, knowing how gold atoms pack into crystals, that there are about 2000 gold atoms in one 4 nm diameter gold nanoparticle.” Recently, a Sustainable Nano reader wrote in to ask about … Continue reading

Publication Summary: How do different kinds of bacteria interact with different kinds of nanoparticles?

This post is part of our ongoing series of public-friendly summaries describing research articles that have been published by members of the Center for Sustainable Nanotechnology. Vivian Feng, a chemistry professor at Augsburg College, is the first author of this paper, which was a collaboration with undergraduate and graduate students as well as other CSN … Continue reading
