Speakers made from carbon nanotube sheets that are a fraction of the width of a human hair can both generate sound and cancel out noise — properties ideal for submarine sonar to probe the ocean depths and make subs invisible to enemies. That’s the topic of a report on these “nanotube speakers,” which appears in ACS’ Nano Letters.

Painting stripes on walls is a popular decorating technique that gives the painted room the illusion of having a larger area. But to properly create this decor, you need to be careful that the stripes that you paint are consistent in their width and pattern. So before painting the stripes, you have to mark them so you know which stripes to paint a particular color

Wallpaper installation can be tricky, especially when it comes to determining exactly how many rolls of wallpaper you need. While some people are satisfied with simply guessing the number of rolls, you can be more efficient and cost effective by computing the wallpaper measurements. Here’s how

Scientists in Texas are reporting the development of a “nanodragster” that may speed the course toward development of a new generation of futuristic molecular machines. The vehicle — only 1/50,000th the width of a human hair – resembles a hot-rod in shape and can outperform previous nano-sized vehicles. Their report is in ACS’ Organic Letters, a bi-weekly journal.
