Technology and Health News
Researchers have made a fabric, made from polyester fibres which is coated with millions of small silicone filaments. This the most water-resistant clothing which was ever created by man.
Because of the nanometre-scaled filaments, a coating which stops water particules from going through the coating to the polyester fibres which are underneath. This mixture between a hydrophobic surface and a nanostructure coating leads to a super-hydrophobic effect.
This is similar to the surface of Lotus leaves.
There are many applications for this: from stain resistant clothing (see video) to reducing water drag in submarines or swimmers. This could lead in a drag decrease of up to 20%.
Here's a little video from the Today Show with a stain resistant shirt which usese nano-technology (Nano-Tex material).
An amazing material was developed by Chinese scientists which is composed of carbon nanotube films and has a possible application (among otther) to produce the world's thinnest speakers.
Nanotubes, are a new carbon breed of material, which is 1000 times smaller than the width of a hair and can give sound with the "same quality of conventional speakers". This, however, does not require magnets of any sort or moving parts for that matter at all.
You can easilly imagine speakers everywhere: on walls, helmets, thinner ear plugs or even on your shirt.
This is possible because very thin carbon nanotube films, with the right frequency of electric currents, can emit sound. It also has a wide frequency response range and high sound pressure.
It also turns out that they are practical to build, and are even stretchable. Here is a video with the actual speackers embedded in a flag!
