"Nanograss" boosts the efficiency of organic solar cells

"Nanograss" boosts the efficiency of organic solar cells | Managing Technology and Talent for Learning & Innovation | Scoop.it
Researchers at the University of Massachusetts Amherst, Stanford University and the Dresden University of Technology have developed a long sought-after nanostructure that can significantly increase the efficiency of organic solar cells. Their "nanograss," a dense array of vertical nanopillars, can capture photons at a very high efficiency and could also lead to cheaper and more advanced 3D transistors, photodetectors and charge storage devices.

Ultra-thin diamond nanothreads are strongest, stiffest materials

Ultra-thin diamond nanothreads are strongest, stiffest materials | Managing Technology and Talent for Learning & Innovation | Scoop.it
Diamond nanothread visualization (credit: Penn State University) Scientists have discovered how to produce ultra-thin diamond nanothreads that promise
Carlos Fosca's insight:

"Scientists have discovered how to produce ultra-thin “diamond nanothreads” that promise extraordinary properties, including strength and stiffness greater than that of today’s strongest nanotubes and polymers.

A paper describing this discovery by a research team led by John V. Badding, a professor of chemistry at Penn State University, was published in the September 21, 2014 issue of the journal Nature Materials.

Potential applications that most interest Badding are those that would be vastly improved by having exceedingly strong, stiff, and light materials, including lighter, more fuel-efficient, and therefore less-polluting vehicles."

Nanotech roundup: electricity from sewage, and self-cleaning solar panels

Nanotech roundup: electricity from sewage, and self-cleaning solar panels | Managing Technology and Talent for Learning & Innovation | Scoop.it
Liesbeth Venema: This month's roundup includes a device for squeezing energy from wastewater, and a coating to keep solar panels clean
Carlos Fosca's insight:

"An attractive way is to enlist the help of microbes, which have already been optimised by natural selection over millions of years to extract energy from waste products. Researchers at Stanford have designed a microbial energy-harvesting device that looks like a battery, where the positive (anode) electrode consists of carbon nanomaterial coated with microorganisms and the negative (cathode) electrode contains silver oxide".
