Nanotech: Fuzzy fabric goes into production
Once in a while it’s useful to note when science transitions to technology and when some technologies leave the laboratory and enter production. Nanotechnology has a good track record in this regard. Born in experiments with molecular chemistry, the science of nanotechnology has found many routes into high-tech products. Here’s a recent case in point: [...]

Printable tagging with Nano-RFID
RFID – Radio Frequency Identification – started in the 1970’s at the edge of technological capability. The idea of ID tags that could broadcast their identification seemed useful, particularly for expensive inventory that could justify the cost. The idea was also somewhat controversial, as it was easy to envision privacy issues with tags applied to [...]
New study: Why silk is so strong
It’s been said for quite some time that silks, especially spider silks, are pound-for-pound stronger than steel. Silk is also famously flexible. Now there is a study from the Massachusetts Institute of Technology (MIT, Cambridge, USA) that explains how this strength is the product of something that shouldn’t be that strong – simple hydrogen bonds [...]

Add to the nanokit: Boron nitride nanotubes
There are many possible nanotubes. Some, like carbon nanotubes, are made from common (and therefore inexpensive) material and relatively easy to manufacture and manipulate. Others, such as boron nitride nanotubes, have great potential but are famously difficult to manufacture – which is to say prohibitive for widespread use. The potential is clear: Boron nitride nanotubes [...]

Lasers make nanoyarn
Add another ‘nano’ contraction to the list: Nanoyarn. In this case, the ‘yarn’ is composed of nanotubes created from boron nitride. (Boron nitride is what makes ‘clown white’ white.) The word yarn is suggestive of possible uses and reasonably accurate. The new nanoyarn, manufactured for the first time by the U.S. Department of Energy Jefferson [...]

Key technique: Fluid-process nanotubes like polymers
Carbon nanotubes are the lab stars of nanotechnology. They can conduct electricity better than copper. They can behave like a metal – or a semiconductor. They can be 10 times stronger than steel. They can be controlled by heat or by magnetism. As coated tubes, they can contain medicine. In short, they’re extremely versatile, which [...]
