Nanotechnology's next trick could be a real invisibility cloak


Hands up if you haven't dreamt of becoming invisible at times? Researchers have too and are working on proving it's not so impossible.

Alongside some practical applications, such as self-cleaning windows, salads that contain vaccine, and tiny laptop chargers, researchers are working with nanotechnology to make invisibility, or at least a version of it, reality.

Broadly defined as the manipulation of matter on such a small scale it cannot be seen by the human eye, nanotechnology is – finally – opening the door to previously unexplored opportunities for technology and business.

The potential application of nanotech-enabled tiny machines has companies like Google exploring future uses – especially in medicine – while the University of Pennsylvania in the United States has opened a A$92 million ($102 million) nanotechnology research hub in the centre of Philadelphia.

"Wouldn't it be wonderful if you could be like Harry Potter?" Mark Allen, scientific director of the University's Krishna P. Singh Centre for Nanotechnology, told Fairfax Media during a tour of the facility.

"Invisibility is very hard to do but it is possible using metamaterials to bend light at certain angles. It is far from Harry Potter's cloak but you can imagine applications for that."

Allen is referring to work by University of Pennsylvania colleague Nader Engheta that demonstrates an early-stage example of nanotechnology – a "cloaking device" that can bend light waves around an object rendering it effectively invisible.

"There is also a professor working on nanostructures that are self-cleaning," he said. "Imagine if you didn't need to clean your windows or any surfaces in the home."

Another example of how nanotechnology may play a role in the not-so-distant future is tracking food quality in restaurants.

"There are now people using [nanotechnology] chemical sensors where you could map pollution throughout the city or the food quality of a restaurant," Allen said.

World's smallest nanomotor could power cell-sized nanobots for drug delivery
Scientists at the Cockrell School of Engineering at the University of Texas have built and tested what appears to be the world's smallest, fastest, and longest-running nanomotor yet – so small that it could fit inside a single cell. The advance could be used to power nanobots that would deliver specific drugs to individual living cells inside the human body.

In the distant future, when faced with a cancer diagnosis, we might be able to simply ingest a "magic pill" filled with hordes of miniscule nanobots that target individual cancerous cells with drugs and leave the healthy ones unharmed. To power those robots, we need a nanoscale-sized motor that's capable, sufficiently long-lived, and flexible enough for a wide range of applications.

A team of researchers led by Prof. Donglei Fan has produced a nanomotor that might just satisfy those requirements. The device is simple in its structure, being composed of only three parts, which are brought together one by one using a patent-pending technique relying on AC and DC electric fields.

The resulting nanodevice is under 1 micrometer in size in all three dimensions, meaning it's small enough to fit inside a single cell. It was also shown to be significantly more long-lived than previous designs, with the ability to convert electrical energy to mechanical energy and maintain a speed of 18 thousand RPMs – which is comparable to the speed of a jet engine – for an impressive 15 hours of continuous operation.

Integrating nanoarchitectures for highly efficient electrocatalysts
Electrocatalysts play a key role in energy conversion processes. A good electrocatalyst improves energy conversion efficiency, accelerates electrocatalysis and maintains its stability simultaneously. In the past two decades attempts have been made to allow energy conversion technologies to reach a practical usable level. Reporting in Nanotechnology, researchers in Shanghai University design and construct functional nanoarchitectures to contribute to the development of these smart electrocatalyst materials

Chemically enhanced 2D material makes excellent tunable nanoscale light source
(Nanowerk Spotlight) Molybdenum disulfide's (MoS2) semiconducting ability, strong light-matter interaction and similarity to the carbon-based graphene makes it of interest to scientists as a viable alternative to graphene in the manufacture of electronics, particularly photoelectronics (read more: "2D molybdenum disulfide: a promising new optical material for ultra-fast photonics"). In particular, MoS2 has excellent optical properties when deposited as a single, atom-thick layer – unlike graphene, it emits light when excited; albeit relatively poorly.
"While a suspended monolayer MoS2 flake shows photoluminescence efficiencies 100 times higher compared to a suspended bilayer flake, its overall quantum yield is still below 1%, and excitonic emission is spectrally broad at room temperature, Jason C Reed, a PhD student in Professor Ertugrul Cubukcu's Nanoengineered Photonics Group at the University of Pennsylvania, tells Nanowerk. "In contrast, when transferred onto substrates for device integration, quantum yield for MoS2 monolayers is even lower and only 3.5 times higher than that of a bilayer."
Therefore, in order to realize the potential of atomically thin MoS2 as a nanoscale active material in a light source, a considerable enhancement of its emission efficiency is necessary.
And that's exactly what the Penn researchers have done. In new work, published in the February 27, 2015 online edition of Nano Letters ("Wavelength Tunable Microdisk Cavity Light Source with a Chemically Enhanced MoS2 Emitter"), they showed both experimentally and theoretically that two-dimensional (2D) MoS2

Plasmonic ceramic materials key to advances in nanophotonics for extreme operational conditions
Progress in developing nanophotonic devices capable of withstanding high temperatures and harsh conditions for applications including data storage, sensing, health care and energy will depend on the research community and industry adopting new "plasmonic ceramic" materials, according to a commentary this week in the journal Science.

In one promising nanophotonic approach – plasmonics - clouds of electrons called surface plasmons are used to manipulate and control light on the nanometer scale. Plasmonic devices under development often rely on the use of metals such as gold and silver, which are not practical for most industrial applications because they are unable to withstand extreme heating and other harsh conditions. They also are not compatible with the complementary metal–oxide–semiconductor (CMOS) manufacturing process used to construct integrated circuits.

Now researchers are proposing the use of plasmonic ceramics such as titanium nitride and zirconium nitride instead of gold and silver.

Yeh right one more no brainier for the new generation of retards calling something of the 2D type being a material. :iitm:

Tell me what you know which is two dimensional & all around you ........ I know one & its truly of the 2D and should never ever represents a 3D material item!

Nothing 2D about it when it comes to MoS2 as far I know & understand.
And if its not 2D why they using this type of wording?

And this is one application in a Solar cell where they using this MoS2 material in nano size thickness = 3D material & not 2D!

In my reality world everything is only based on a dipole system; where one dipole has an unequal amount of electrons & the equalization movement creates a current flow which we calling electricity. Also to my understanding electrons are always moving on the external material source & not in the internal of any material. = 3D material & will never be of the 2D type.

Thats why the overall amount of surface area is of such importance to create usable flowing excess energy equaling out between two dipoles.

So the articles text is clearly misleading the public & its by design as everything gets lied about in this world of manipulators of knowledge base monopolization.

Because they truly hate if the public finally starts to understand how things really work & they could create there own over unit energy devices simply and cheap.
And this would result in no more enforced usury money demands for the Tribe.


Like these types of ideas things & materials which are already available all over.

because error is repeatedly preached among us, not

feeling that it has a decided majority on its side."
