Wei Feng network on August 24 news, the microbiology research team from Amherst, Mass., has found a new method that can create a biological wire that is 6,000 times thinner than human hair. It is called "Microbial nanowires."
The researchers said that the microbial nanowires are made from genetically modified soil bacteria, the ground-sulfur reducing bacteria. They have a diameter of 1.5 nanometers, which is about one-sixth of that of human hair, but the conductivity is enhanced 2000 times. And it is very durable.
Dr. Derek R.Lovley, the principal researcher of the research team, said that the microbial nanowires can be produced on a large scale because they are made from cheap materials, such as amino acids that can be obtained by fermenting bacteria.
In an interview with the media, Dr. Derek R.Lovley said: "We are very excited about the possibility of synthesizing biological wires. They can be applied to new flexible electronic products and even solar energy devices."
It is understood that this study was funded by the United States Naval Research Office, so microbial nanowires may also be used in the military field. For example, nanowires can supply electricity to microorganisms and produce a gasoline-like fuel called butanol. In addition, nanowires can provide current for some microorganisms and collect signals from pollutants, toxins, or explosives.
For ordinary consumers, the most important use of this kind of microbial nanowires is that they can be applied to smart phones so that small-size mobile phones can have more memory space.
Plywood is the basic wooden product for furniture, is one of the biggest wooden products, is used for plane, boat, train, bus, construction and package etc. It is the one of the main way to save wood resource and improve the usage of wood.Usually poplar, pine, combi, hardwood as the core, the bace&back are the Veneer surface, such as Okoume, Bintangor, Pine, Birch, Poplar, Pencil cedar, Maple, Cherry, White Oak, Sapele, Beech, Red Oak, Ash etc.
