Using a scanning electron microscope the Stanford team captured images of these microbes attaching milky tendrils to the carbon filaments. ou can see that the microbes make nanowires to dump off their excess electronscriddle says.
They describe their nanowire mesh design in the journal ACS Nano. Peidong Yang Bin Liu and colleagues note that harnessing sunlight to split water
The researchers took a page from the paper industry using one of its processes to make a flat mesh out of light-absorbing semiconductor nanowires that
While one-dimensional materials such as carbon nanotubes and nanowires also allow excellent electrostatics and at the same time possess band gap they are not suitable for low-cost mass production due to their process complexities she said.
His team has made ultrathin nanowires that can monitor and influence what goes on inside cells.
#Shrinky Dinks close the gap for nanowires How do you put a puzzle together when the pieces are too tiny to pick up?
to close the gap between nanowires in an array to make them useful for high-performance electronics applications.
Nanowires are extremely fast, efficient semiconductors, but to be useful for electronics applications, they need to be packed together in dense arrays.
Researchers have struggled to find a way to put large numbers of nanowires together so that they are aligned in the same direction and only one layer thick."
"Chemists have done already a brilliant job in making nanowires exhibit very high performance. We just don't have a way to put them into a material that we can handle,
people can make nanowires and nanotubes using any method they like and use the shrinking action to compact them into a higher density."
"The researchers place the nanowires on the Shrinky Dinks plastic as they would for any other substrate,
This allows them to create very dense arrays of nanowires in a simple, flexible and very controllable way.
The shrinking method has added the bonus of bringing the nanowires into alignment as they increase in density.
and the low cost of plastic could have a huge impact on nanowire assembly and processing for applications."
For example, experiments have shown that film made of packed nanowires has properties that differ quite a bit from a crystal thin film."

Until now, the only experimental TFET to meet the International Technology Roadmap for Semiconductors (ITRS) goal of average subthreshold swing below 60 millivolts per decade over four decades of current was a transistor that used nanowires.
By combining semiconducting nanowires and bacteria, researchers can now produce liquid fuel. Three pioneers in the field of synthetic photosynthesis discuss the potential of this technology
Scientists with the U s. Department of energy (DOE)' s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have created a hybrid system of semiconducting nanowires and bacteria
The paper is titled"Nanowire-bacteria hybrids for unassisted solar carbon dioxide fixation to value-added chemicals.""The other corresponding authors and leaders of this research are chemists Christopher Chang and Michelle Chang.
"In our system, nanowires harvest solar energy and deliver electrons to bacteria, where carbon dioxide is reduced and combined with water for the synthesis of a variety of targeted, value-added chemical products."
"By combining biocompatible light-capturing nanowire arrays with select bacterial populations, the new artificial photosynthesis system offers a win/win situation for the environment:
the morphology of the nanowire array protects the bacteria like Easter eggs buried in tall grass
"The system starts with an"artificial forest"of nanowire heterostructures, consisting of silicon and titanium oxide nanowires, developed earlier by Yang and his research group."
"Our artificial forest is similar to the chloroplasts in green plants, "Yang says.""When sunlight is absorbed, photo-excited electron?
hole pairs are generated in the silicon and titanium oxide nanowires, which absorb different regions of the solar spectrum.
"Once the forest of nanowire arrays is established, it is populated with microbial populations that produce enzymes known to selectively catalyze the reduction of carbon dioxide.
"We were able to uniformly populate our nanowire array with S. ovata using buffered brackish water with trace vitamins as the only organic component."

#Nanowire implants offer remote-controlled drug delivery Abstract: Remote-controlled Eradication of Astrogliosis in Spinal cord Injury via Electromagnetically-induced Dexamethasone Release from"Smart"Nanowireswen Gao and Richard Borgenswe describe a system to deliver drugs to selected tissues continuously,
novel vertically aligned electromagnetically-sensitive Polypyrrole Nanowires (Ppynws). Approximately 1-2mm 2 Dexamethasone (DEX) doped Ppynws was lifted on a single drop of sterile water by surface tension,
A team of researchers has created a new implantable drug-delivery system using nanowires that can be controlled wirelessly.
The nanowires respond to an electromagnetic field generated by a separate device, which can be used to control the release of a preloaded drug.
The nanowires are made of polypyrrole, a conductive polymer material that responds to electromagnetic fields. Wen Gao, a postdoctoral researcher in the Center for Paralysis Research who worked on the project with Borgens
grew the nanowires vertically over a thin gold base, like tiny fibers making up a piece of shag carpet hundreds of times smaller than a human cell.
The nanowires can be loaded with a drug and, when the correct electromagnetic field is applied, the nanowires release small amounts of the payload.
This process can be started and stopped at will, like flipping a switch, by using the corresponding electromagnetic field stimulating device,
and transported a patch of the nanowire carpet on water droplets that were used used to deliver it to the site of injury.
The nanowire patches adhere to the site of injury through surface tension Gao said. The magnitude and wave form of the electromagnetic field must be tuned to obtain the optimum release of the drug,
Functional Drug Delivery Using Electromagnetic field-Responsive Polypyrrole Nanowires, "was published in the journal Langmuir. Other team members involved in the research include John Cirillo,
A 1-2 millimeter patch of the nanowires doped with dexamethasone was placed onto spinal cord lesions that had been exposed surgically,
and those that received a nanowire patch but were exposed not to the electromagnetic field. In some cases, treated mice had no detectable GFAP signal.
#Nanowire clothing could keep people warm without heating everything else To stay warm when temperatures drop outside,
But scientists have developed now a novel nanowire coating for clothes that can both generate heat
the special nanowire cloth trapped body heat far more effectively. Because the coatings are made out of conductive materials,
so Bailie did it manually. e used a sheet of plastic with silver nanowires on it, he said. hen we built a tool that uses pressure to transfer the nanowires onto the perovskite cell, kind of like a temporary tattoo.
You just need to rub it to transfer the film. Remarkable efficiency For the experiment, the Stanford team stacked a perovskite solar cell with an efficiency of a 12.7 percent on top of a low-quality silicon cell with an efficiency of just 11.4 percent. y combining two cells
