It contains layers of gold electrodes just a few hundred nanometres thick, sandwiched between layers of polyimide plastic to form a «nanomembrane».
We used a combination of bulk electrochemical measurements and scanning electrochemical cell microscopy with submicrometer resolution to show that grain - boundary surface terminations in gold electrodes are more active than grain surfaces for electrochemical carbon dioxide (CO2) reduction to carbon monoxide (CO) but not for the competing hydrogen (H2) evolution reaction.
The electro - optical converter consists of two parallel gold electrodes of about 29 µm in length, which is one third of the diameter of a human hair.
At both ends of the resulting detector, they deposit gold electrodes.
The developed analysis method was applied to various single - molecule junctions, i.e., those of 1,4 - butanediamine (DAB), pyrazine (PY), 4,4» - bipyridine (BPY), and fullerene (C60), sandwiched by gold electrodes, and the different molecular - dependent electronic and structural fluctuations were demonstrated.
In 2003, however, researchers at the University of Groningen in the Netherlands who mounted single molecules of diarylethene between gold electrodes found that, even though the switches could be turned off by visible light, they could not then be turned back on by ultraviolet.
The current prototype doesn't have electrodes; the researchers plan to add gold electrodes and test the scaffold in rats.
Its interior is lined with a series of gold electrodes, each dotted with thousands of identical short strands of DNA called aptamers.
The researchers used a scanning tunneling microscope technique that they have pioneered to make junctions comprising a single cluster connected to the two gold electrodes, which enabled them to characterize its electrical response as they varied the applied bias voltage.
Bonnie Choi, a graduate student in the Roy group and co-lead author of the work, created a single cluster of geometrically ordered atoms with an inorganic core made of just 14 atoms — resulting in a diameter of about 0.5 nanometers — and positioned linkers that wired the core to two gold electrodes, much as a resistor is soldered to two metal electrodes to form a macroscopic electrical circuit (e.g. the filament in a light bulb).
A chemical group at one end anchors each aptamer to the gold electrode.
Columbia researchers wired a single molecular cluster to gold electrodes to show that it exhibits a quantized and controllable flow of charge at room temperature.
Researchers at the University of Minnesota in Minneapolis have invented a new ultralow power technique to trap nanoparticles in the sub-10 nm gaps between two gold electrodes.
«In our new work, we made very long (up to millimetres) and ultra-narrow (less than 10 nm) gaps between two gold electrodes,» he says.
A gold electrode coated with nanoclusters of indium phosphide absorb incoming photons of light (that is the wavy line marked «hv» in the image).
