How can nanotechnology preserve stone cultural heritage sites?

Note: There has been much public discussion recently around preservation of public monuments. This blog post is about how science can play an important role in preserving historical monuments. Although people, including scientists, must make judgments about historical preservation, nothing in this post is intended to express any opinion on recent public discussions about those …

Engineered gold nanoparticles can be like ice cream scoops covered in chocolate sprinkles

There are many ways to interrogate molecular phenomena. You might think that this is restricted to physical measurements such as direct observation with a microscope, a laser, or more seemingly arcane observation with nuclear magnetic resonance (NMR). But I’m happy to report that observation of computer simulations is yet another, as long as our models …

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 …

The Mystery of the Surface: Your Kitchen Table is Far From Simple

The last time I played with Google Street View, I saw my car in the driveway and could practically count the teeth on a jack o’ lantern on my porch. I thought, wouldn’t it be amazing if I could drop-land on the surface of a nanoparticle and take a look around the scenery? What about …

Nanoparticles With Your Coffee? A Java-Infused Science Experiment!

Many of us couldn’t make it through a day without a cup or two of our favorite caffeinated beverage. I usually start my day with a warm cup of coffee or tea. In fact, more than 50% of adults in America drink coffee on a daily basis, averaging about 3 cups a day. In the US, …
