10 nano-engineered gadgets to make the trend soon

nano tech
Nanotechnology or nanotech, the study of the controlling of matter on an atomic and molecular scale, has brought about a revolution in the field of science and technology, for it has the potential to create many new materials and devices with a vast range of applications, such as in medicine, electronics and energy production. Designers have taken a leaf from nanotech and have created gadgets that are worth appreciation, and here we have listed a few for your delight.

Nanoelectronic devices

[edit]Radios

Nanoradios have been developed structured around carbon nanotubes.[8]

[edit]Computers

Simulation result for formation of inversion channel (electron density) and attainment of threshold voltage (IV) in a nanowire MOSFET. Note that the threshold voltage for this device lies around 0.45V.
Nanoelectronics holds the promise of making computer processors more powerful than are possible with conventional semiconductor fabrication techniques. A number of approaches are currently being researched, including new forms of nanolithography, as well as the use of nanomaterials such as nanowires or small molecules in place of traditional CMOS components. Field effect transistors have been made using both semiconducting carbon nanotubes[9] and with heterostructured semiconductor nanowires.[10]

[edit]Energy production

Research is ongoing to use nanowires and other nanostructured materials with the hope to create cheaper and more efficient solar cells than are possible with conventional planar silicon solar cells.[11] It is believed that the invention of more efficient solar energy would have a great effect on satisfying global energy needs.
There is also research into energy production for devices that would operate in vivo, called bio-nano generators. A bio-nano generator is a nanoscale electrochemical device, like a fuel cell or galvanic cell, but drawing power from blood glucose in a living body, much the same as how the body generates energy from food. To achieve the effect, an enzyme is used that is capable of stripping glucose of its electrons, freeing them for use in electrical devices. The average person's body could, theoretically, generate 100 watts of electricity (about 2000 food calories per day) using a bio-nano generator.[12] However, this estimate is only true if all food was converted to electricity, and the human body needs some energy consistently, so possible power generated is likely much lower. The electricity generated by such a device could power devices embedded in the body (such as pacemakers), or sugar-fed nanorobots. Much of the research done on bio-nano generators is still experimental, with Panasonic's Nanotechnology Research Laboratory among those at the forefront.

[edit]Medical diagnostics

There is great interest in constructing nanoelectronic devices[13][14][15] that could detect the concentrations of biomolecules in real time for use as medical diagnostics,[16] thus falling into the category of nanomedicine.[17] A parallel line of research seeks to create nanoelectronic devices which could interact with single cells for use in basic biological research.[18] These devices are called nanosensors. Such miniaturization on nanoelectronics towards in vivo proteomic sensing should enable new approaches for health monitoring, surveillance, and defense technology.

Nanofibers Clean Sulfur from Fuel

Nanofibers Clean Sulfur from Fuel

Dec. 17, 2012 — Sulfur compounds in petroleum fuels have met their nano-structured match. University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively than traditional materials. Such efficiency could lower costs and improve performance for fuel-based catalysis, advanced energy applications and toxic gas removal.

Nanofibers of metal oxide provide lots of highly reactive surface area for scrubbing sulfur compounds from fuel. Sulfur has to be removed because it emits toxic gasses and corrodes

RISE OF THE MOLECULAR MACHINES


A molecular shuttle 

Fraser Stoddart, a chemist at Northwestern University, US, produced one of the early prototype molecular machines in 1994 (fig?1).2 The machine has a track with two stations and a shuttle that can slide along between them. The shuttle can't escape from the end of the track because there are bulky stopper groups at both ends which it can't fit over. 
Stoddart's molecular shuttle - chemical structures
Fig 1 - The key parts of Stoddart's molecular shuttle are the two stations (blue), the shuttle (orange) and the bulky stoppers (green)
The intermolecular forces that exist between the shuttle and the different points on the track determine where it sits. Because the shuttle is made from non-polar, aromatic building blocks, the Pi-Pi stacking intermolecular forces between it and the aromatic ring-based stations are quite strong. The forces between the shuttle and the track made of polyether chains are much weaker, as there are no aromatic moieties to stack against.
