Quantum dots for eyes treatment

Tiny particles found in televisions and tablets could be used to provide relief from eye infections. Researchers are investigating the use of tiny particles found in the latest electronic displays to fight eye infections. 
Quantum dots are small semiconductor particles that are a key component in nanotechnology. 
A new study, published in ACS Nano, reported on the use of quantum dots as an ingredient in eye drops for the treatment of bacterial keratitis.
Researchers manufactured quantum dots by heating spermidine, a compound that boosts the effectiveness of antibiotics. 
They found that the quantum dots disrupted bacterial cells while leaving animal cells unscathed.
The authors conclude that the new quantum dots are a potential alternative to conventional eye drop treatments for bacterial keratitis. 
Current treatments for the eye infection include steroid drops, but these can result in scarring of the cornea.

Intel's upcoming 10-nanometer chip manufacturing technology

At long last, chip giant  Intel  (NASDAQ: INTC) opened up about its upcoming 10-nanometer chip manufacturing technology, at its first-ever Technology and Manufacturing Day. The company has -- frustratingly -- kept key details of this technology under wraps for years now, but Intel is now putting them out there for all to see.  Without further ado, let's look at what Intel had to tell us about this new tech. A large jump in density Let's talk performance Competitive comparison and no yield information Image source: Intel. Chipmakers generally like to reduce the area of its transistors with major new technology shifts. This area reduction is important in reducing transistor costs on a yield-normalized basis, a really important factor for product cost. Chipmakers are ultimately able to cram more features and functionality into a chip while maintaining reasonable cost structures. Intel says that in moving from 14 nanometers to 10, it's delivering an incre...

Nano thin film Barium Stannate :New revolution to electronics and solar industry

A team of researchers, led by the University of Minnesota, have discovered a new nano-scale thin film material with the highest-ever conductivity in its class. The new material could lead to smaller, faster, and more powerful electronics, as well as more efficient solar cells. The discovery is being published today in  Nature Communications , an open access journal that publishes high-quality research from all areas of the natural sciences. Researchers say that what makes this new material so unique is that it has a high conductivity, which helps electronics conduct more electricity and become more powerful. But the material also has a wide bandgap, which means light can easily pass through the material making it optically transparent. In most cases, materials with wide bandgap, usually have either low conductivity or poor transparency. "The high conductivity and wide bandgap make this an ideal material for making optically transparent conducting films which could be used...

Building blocks of nanoelectronics

The team of researchers headed by Prof. Dr. Sabine Maier, Prof. Dr. Milan Kivala and Prof. Dr. Andreas Görling has successfully assembled and tested conductors and networks made up of individual, newly developed building block molecules. These could in future serve as the basis of components for optoelectronic systems, such as flexible flat screens or sensors. The FAU researchers have published their results in the journal  Nature Communications . Lithographic techniques in which the required structures are cut from existing blocks are mainly employed at present to produce micro- and nano-electronic components. 'This is not unlike how a sculptor creates an object from existing material by cutting away what they do not need. How small we can make these structures is determined by the quality of the material and our mechanical skills,' explains Prof. Dr. Sabine Maier from the Chair of Experimental Physics. "We now have something like a set of Lego bricks for use in the ...
