Controlling the Movement of Water Through Nanotube Membranes

Rensselaer_Nanotube_Wetting.jpg

By fusing wet and dry nanotechnologies, researchers at Rensselaer Polytechnic Institute have found a way to control the flow of water through carbon nanotube membranes with an unprecedented level of precision. The research could inspire technologies designed to transform salt water into pure drinking water almost instantly, or to immediately separate a specific strand of DNA from the biological jumble.

Nanotechnology Meets Biology and DNA Finds Its Groove

The object of fascination for most is the DNA molecule. But in solution, DNA, the genetic material that hold the detailed instructions for virtually all life, is a twisted knot, looking more like a battered ball of yarn than the famous double helix. To study it, scientists generally are forced to work with collections of molecules floating in solution, and there is no easy way to precisely single out individual molecules for study.

Mighty Nanofibers Could Mean Stronger, Lighter Materials

Bigger may be better, but tinier is stronger. So say scientists at the Technion-Israel Institute of Technology, who have shown that tiny polymer nanofibers become much stronger when their diameters shrink below a certain size. Their research could make possible stronger fabrics that use less material.

Self-Assembling Nano-Ice Discovered; Structure Resembles DNA

20061211helix.jpg

UNL Chemistry professor Xiao Cheng Zeng and his team have found double helixes of ice molecules that resemble the structure of DNA and self-assemble under high pressure inside carbon nanotubes. This discovery could have major implications for scientists in other fields who study the protein structures that cause diseases such as Alzheimer's and bovine spongiform ecephalitis (mad cow disease).

Researchers at the Georgia Institute of Technology have developed a technique to study how unicellular micro-algae, known as diatoms, create their complex cell walls. Researchers hope to learn how diatoms assemble these nanometer-patterned, intricate micro-architectures to find better methods for creating nanomaterials in the laboratory.
