Bacterial nanowires (also known as microbial nanowires) are electrically conductive appendages produced by a number of bacteria most notably from the Geobacter and Shewanella genera. [ 1 ] [ 2 ] Conductive nanowires have also been confirmed in the oxygenic cyanobacterium Synechocystis PCC6803 and a thermophilic , methanogenic coculture ...
To incorporate nanowire technology into industrial applications, researchers in 2008 developed a method of welding nanowires together: a sacrificial metal nanowire is placed adjacent to the ends of the pieces to be joined (using the manipulators of a scanning electron microscope); then an electric current is applied, which fuses the wire ends ...
Most types of molecular wires are derived from organic molecules. One naturally occurring molecular wire is DNA.Prominent inorganic examples include polymeric materials such as Li 2 Mo 6 Se 6 [1] and Mo 6 S 9−x I x, [2] [3] [4] [Pd 4 (CO) 4 (OAc) 4 Pd(acac) 2], [5] and single-molecule extended metal atom chains (EMACs) which comprise strings of transition metal atoms directly bonded to each ...
A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery.Some designs (silicon, germanium and transition metal oxides), variations of the lithium-ion battery have been announced, although none are commercially available.
Molecular electronics [6] is a technology under development brings hope for future atomic-scale electronic systems. A promising application of molecular electronics was proposed by the IBM researcher Ari Aviram and the theoretical chemist Mark Ratner in their 1974 and 1988 papers Molecules for Memory, Logic and Amplification (see unimolecular ...
Inorganic nanomaterials, (e.g. quantum dots, [29] nanowires, and nanorods) because of their interesting optical and electrical properties, could be used in optoelectronics. [30] Furthermore, the optical and electronic properties of nanomaterials which depend on their size and shape can be tuned via synthetic techniques.
Researchers at the University of California, Los Angeles have successfully developed a "nanotube ink" for manufacturing flexible batteries using printed electronics techniques. [18] A network of carbon nanotubes has been used as a form of electronically conducting nanowires in the cathode of a zinc-carbon battery. Using nanotube ink, the carbon ...
