The size of the materials in nanotechnology is one of the most important factors that power and define the properties of the nanomaterials. But there are many different techniques for measuring that size, and depending on the measurement methods, the results may vary! It doesn’t mean the actual lengths or diameters of the materials change: …

Have you ever heard the phrase “walking on eggshells”? The phrase is usually meant to convey the message that you should take care in not disrupting or offending someone. It turns out, though, that you can actually walk on eggshells without breaking them. This is achievable because the person’s weight is equally distributed over the …

Almost 4 years ago now (wow I’m getting old) I wrote a blog post about the Invisible Remnants of Dead Stuff Hiding in the Water called natural organic matter, or NOM. Well, some colleagues and I recently published a new paper entitled “Natural organic matter concentration impacts the interaction of functionalized diamond nanoparticles with model …

How do we "see" nanoparticles when they're too small to view with a normal microscope? In this episode we interview Kelly Zhang, a graduate student in the Center for Sustainable Nanotechnology who recently published a paper about a new way to use NMR technology (like MRI for chemistry) to study the behavior of molecules that …
