Some nanostructures can be improved after fabrication by a new nanotech procedure that transiently and selectively liquifies the structures to remove defects.
By adding carbon nanotubes to catalytic nanowires, nanotechnology has produced simple nanomotors that can surpass biological motors (somewhat).
Forests of spiraling nanotrees made from lead sulfide nanowires may lead to new nanotech approaches for producing one-dimensional nanostructures based on designed dislocations rather than metal catalysts to control growth.
The nanotechnology of engineering atomic layer interfaces to produce desired properties—in this case, something called ‘improper ferroelectricity’—promises a technological revolution that may be comparable to the development of modern electronics. From a Stony Brook University news release via ScienceDaily: In the 10 April issue of Nature [abstract], a new artificial material is revealed that marks… Continue reading Nanotechnology engineers atomic layer interfaces to produce new electronic materials
In a proof-of-concept demonstration, large area graphene films several atomic layers thick were inexpensively produced.
Using nanotechnology to control the spin of a single electron in a carbon nanotube might lead to replacing conventional semiconductor transistors with a carbon nanotube or single molecule.
European nanotechnology researchers have moved a gold cargo about 500 nm along a carbon nanotube ‘Monorail”.
IBM scientists provided a proof-of-concept demonstration of a new type of nanotechnology-enabled computer memory in which magnetic domain walls are moved along a nanowire “racetrack”.
A proof-of-concept application of nanotechnology to fabricate transparent organic light emitting diodes (OLEDS) small enough to serve as pixels in high-resolution displays might lead to products like flexible color monitors and “heads-up” displays in car windshields. From a Purdue University press release “Engineers make first ‘active matrix’ display using nanowires“: Engineers have created the first… Continue reading Nanotechnology fabricates OLEDS for active matrix displays
Phil McKenna at NewScientist.com news service describes a nanotechnology advance that turns radiation directly into electricity, leading us to wonder if it thus simultaneously provides a use for nuclear waste. This nanotech application appears to be in the early stages of development, so aside from questions of just how efficient and how expensive it would… Continue reading Nanotechnology to produce electricity from nuclear waste?
