In order for a current to be generated by the solar cell electrons must be transferred from polymer to fullerene within the device.

But the difference between electron energy levels for the standard polymer-fullerene is large enough that electron transfer between them is difficult.

Steven Bottle a professor of nanotechnology and molecular science at Queensland University of Technology says the most impressive element of the study is the combination of two powerful imaging techniques into one nanomaterial.

It s been a dream of mine for many years to have a nanomaterial that incorporates both fluorescence

Now, a team of MIT researchers wants to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production

They are also working on incorporating electronic nanomaterials, such as graphene, into plants. ight now, almost no one is working in this emerging field,

Among nanomaterials, carbon-based nanoparticles such as carbon nanotubes and graphene have shown promising results, but they suffer from relatively low electrical conductivity,

If left alone, these nanomaterials would remain suspended and dispersed evenly in water. But when exposed to UV LIGHT,

a nanomaterial in the fullerene molecular group, provide strong protection against breakdown of the insulation plastic used in high-voltage cables.

It is sufficient to add very small amounts of fullerene to the insulation plastic for it to withstand a voltage that is 26 per cent higher, without the material breaking down,

Fullerenes prevent electrical trees from forming by capturing electrons that would otherwise destroy chemical bonds in the plastic.

In recent years, other researchers have experimented with fullerenes in the electrically conductive parts of high-voltage cables.

Lina Bertling The Chalmers researchers have demonstrated now that fullerenes are the best voltage stabilizers identified for insulation plastic thus far.

Fullerenes turned out to be the type of additive that most effectively protects the insulation plastic.

The team's discovery comes after nearly a century of failed attempts by other labs to compress separate carbon-containing molecules like liquid benzene into an ordered diamond-like nanomaterial.

The nanothread also may be the first member of a new class of diamond-like nanomaterials based on a strong tetrahedral core.

#Nanomaterials to preserve ancient works of art Little would we know about history if it weren't for books and works of art.

In an effort to overcome the limitations of traditional restoration techniques the team has developed promising nanomaterials

This is where the NANOFORART (Nanomaterials for the conservation and preservation of movable and immovable artworks) project comes in.

The three-year project which ends this month has developed advanced nanomaterials for preventive conservation of works of art.

This involved nanomaterials that are physico-chemically compatible with the components of works of art

The advanced nanomaterials we have been working on allow for a more precise control of the restoration intervention for example controlled cleaning can be carried out using microemulsions and chemical hydrogels instead of traditional cleaning methods.

This is the reason why we are proposing a new project within the Horizon 2020 call named NANORESTART (Nanomaterials for the RESTORARTION of the works of modern ART to highlight the new start with respect to classic art conservation) that aims

He stated With nanomaterial technology we can detect the tumor early and kill it on sight at the same time.

Scientists identify this certain biomarker that is specific to a certain tumor then conjugates this biomarker on the surface of the nanocarrier that only has the expression for that specific kind of cancer cell.

The sectors focused on the use of these nanomaterials are diverse; nanoplatelets impart new properties to materials;

and where the use of nanomaterials is an opportunity explains Licea Jimenez. According to the specialist at CIMAV the research is applied already in some concept testing for mechanical and thermal modification in the construction industry.

Even some of the companies we have worked with mentioned in several forums that they have had a good response in the use of these nanomaterials.

Researchers at Drexel University and Dalian University of Technology in China have engineered chemically a new electrically conductive nanomaterial that is flexible enough to fold

By using one nanocarrier to contain two different drugs we can potentially reduce their dose

The nanocarriers are made from a polymer called polyethylene glycol (PEG) to which researchers attach the cancer-killing drug camptothecin (CPT) like bunches of grapes on a vine.

The resulting nanocarrier is shaped like a flower#hence the term nanodaisy. The idea came from thinking actively about folding proteins in nature noted Gu referring to the way amino acids can assemble themselves into thousands of different shapes.

This approach to growing nanomaterials will improve the efficiency of various devices including solar cells and fuel cells.

#Researchers improve thermal conductivity of common plastic by adding graphene coating (Phys. org) A team of engineering

Published in Nature Nanotechnology researchers from Cardiff University have unveiled a new method for viewing nanodiamonds inside human living cells for purposes of biomedical research.

Nanodiamonds are very small particles (a thousand times smaller than human hair) and because of their low toxicity they can be used as a carrier to transport drugs inside cells.

There is a growing consensus among scientists that nanodiamonds are one of the best inorganic material alternatives for use in biomedical research, because of their compatibility with human cells,

Previous attempts by other research teams to visualise nanodiamonds under powerful light microscopes have run into the obstacle that the diamond material per se is transparent to visible light.

Locating the nanodiamonds under a microscope had relied on tiny defects in the crystal lattice which fluoresce under light illumination.

and in turn the image gleaned from the microscopic exploration of these flawed nanodiamonds, is sometimes also unstable.

In their latest paper, researchers from Cardiff University's Schools of Biosciences and Physics showed that non-fluorescing nanodiamonds (diamonds without defects) can be imaged optically

By focusing these laser beams onto the nanodiamond, a high-resolution CARS image is generated. Using an in-house built microscope,

the research team was able to measure the intensity of the CARS light on a series of single nanodiamonds of different sizes.

The nanodiamond size was measured accurately by means of electron microscopy and other quantitative optical contrast methods developed within the researcher's lab. In this way,

The next step for us will be to push the technique to detect nanodiamonds of even smaller sizes than what we have shown so far

#Materials for the next generation of electronics and photovoltaics One of the longstanding problems of working with nanomaterials substances at the molecular and atomic scale is controlling their size.

Hersam a professor of materials science engineering chemistry and medicine at Northwestern University has developed a method to separate nanomaterials by size

It turns out that carbon nanomaterials are hydrophobic so water will roll right off of them he says.

While we have demonstrated only the construction of graphene-based structures in this study we strongly believe that the new technique will be able to serve as a general method for the assembly of a much wider range of nanomaterials concluded Franklin Kim the principal investigator of the study y

Using EGCG IBN researchers have engineered successfully nanocarriers that can deliver drugs and kill cancer cells more efficiently.

Our green tea nanocarrier not only delivered protein drugs more effectively to the cancer cells, the combination of carrier and drug also dramatically reduced tumor growth compared with the drug alone.

To solve this problem IBN has designed a therapeutic nanocarrier for drug delivery using novel compounds derived from EGCG.

Using the new nanocarrier twice as much drug accumulated in the cancer cells indicating an improved tumor targeting ability.

IBN has filed a patent on their green tea nanocarrier and is developing this technology for clinical applications.

Like tiny submarines these versatile nanocarriers can navigate in the watery environment surrounding cells and transport their guest molecules through the membrane of living cells to sequentially deliver their cargo.

For practical applications these nanocarriers are highly desirable explains Francisco Raymo professor of chemistry in the University of Miami College of Arts and Sciences and lead investigator of this project.

The new nanocarriers are15 nanometers in diameter. They are made supramolecular constructs up of building blocks called amphiphilic polymers.

These nanocarriers hold the guest molecules within the confines of their water-insoluble interior and use their water-soluble exterior to travel through an aqueous environment.

"said physicist Oleg Gang who led the study at the Center for Functional Nanomaterials (CFN) at the U s. Department of energy's Brookhaven National Laboratory.

For criminals to circumvent the process they would have to somehow find out which nanomaterials were added to a product to create its unique thermal signature then add the right mix of nanoparticles to their own counterfeit product to recreate it no easy feat.

#Inner Space of Carbon nanotubes Could act as a Template for Synthesis of Linear-Chain Nanodiamonds The inner space of carbon nanotubes can act as a template for the synthesis of nanodiamond-like carbon chains.

this templated polymerization approach paves the way for the design of novel one-dimensional nanomaterials. Nanosized materials such as nanowires offer unique properties that are completely distinct from those of the bulk materials.

Hisanori Shinohara from Nagoya University in Japan and his colleagues have developed a method that uses carbon nanotubes as a reaction vessel for the templated polymerization of linear-chain nanomaterials.

Shinohara and his colleagues were able to synthesize a one-dimensional nanodiamond polymeric structure by a relatively simple annealing technique.

The new nanomaterial is extremely moisture sensitive and at the same time chemically stable, transparent and easy to fabricate into nanosheets.

scientists from the Helmholtz Zentrum Mnchen (HMGU) and the Ludwig-Maximilians-Universitt (LMU) in Munich have developed nanocarriers that site-selectively release medicines/drugs at the tumor site in human and mouse lungs.

Selective drug transport verified in human tissue for the first time The Munich scientists have developed nanocarriers that only release the carried drugs in lung tumour areas.

Tumour specific proteins were used to release drugs from the nanocarriers Tumour tissue in the lung contains high concentrations of certain proteases,

The scientists took advantage of this by modifying the nanocarriers with a protective layer that only these proteases can break down,

and so the medicines stay protected in the nanocarrier.""Using these nanocarriers we can very selectively release a drug such as a chemotherapeutic agent specifically at the lung tumour,"reports research group leader Meiners."

"We observed that the drug's effectiveness in the tumour tissue was 10 to 25 times greater compared to

"Further studies will now be directed to examine the safety of the nanocarriers in vivo and verify the clinical efficacy in an advanced lung tumour mouse model l
