Why Nanomaterials are so unique?

Why are Nanomaterials so Special and What is the Center for

Solar powered houseNow that you’ve somehow gotten to this blog, you’re probably wondering, “Where am I? What is this ‘Center for Sustainable Nanotechnology’?”

Our “center” is actually a group of people who care about our environment and are doing collaborative research to help ensure that our planet will be habitable hundreds of years from now – in other words, that the things we do every day as humans will be sustainable in the long run.

Now you’re probably wondering what that has to do with nanotechnology, right? Well, it turns out that nanoparticles – chunks of materials around 10, 000 times smaller than the width of a human hair – may provide new and important solutions to many of the world’s problems. For example, new kinds of nanoparticle-based solar cells are being made that could, in the future, be painted onto the sides of buildings.

The power of nanoparticles: surface area increases as particle size decreases.

How are nanoparticles able to do all this stuff?? The key idea is simple – what’s really important in many materials is their surface, and so the reason to use nanoparticles is that if you take a chunk of a material and chop it up into tiny pieces, there’s a lot more surface area in total than if it was just one big chunk. By chopping it up into tiny pieces we can get more “oomph” out of small amount of stuff, and do things like make better batteries, build more fuel-efficient cars, and reduce pollution.

What’s the (potential) problem? Well, these tiny little chunks of materials are so small that they can move around and do things in ways that we don’t fully understand. For example, really tiny particles could potentially be absorbed through skin. In the environment, nanoparticles might be able to be absorbed into insects or fish that are at the bottom of the food chain for larger animals, including us.

Before nanoparticles get incorporated into consumer products on a large scale, it’s our responsibility to figure out what the downsides could be if nanoparticles were accidentally released into the environment. However, this is a huge challenge because nanoparticles can be made out of different stuff and come in many different sizes, shapes, and even internal structures.

Paper battery?

WASHINGTON (Reuters) – Ordinary paper could one day be used as a lightweight battery to power the devices that are now enabling the printed word to be eclipsed by e-mail, e-books and online news.
Scientists at Stanford University in California reported on Monday they have successfully turned paper coated with ink made of silver and carbon nanomaterials into a "paper battery" that holds promise for new types of lightweight, high-performance energy storage.
The same feature that helps ink adhere to paper allows it to hold onto the single-walled carbon nanotubes and silver nanowire films

In this context, the text offers an extremely timely and valuable perspective on the first of these materials to attain such enormous attention and is an excellent reference by which to direct analogous research towards other two-dimensional nanomaterials.
