Pluto's atmosphere deflects solar wind and generates nitrogen ions.
 
Pluto Wags its Tail: New Horizons Discovers a Cold, Dense Region of Atmospheric Ions Behind Pluto

New Horizons has discovered a region of cold, dense ionized gas tens of thousands of miles beyond Pluto -- the planet’s atmosphere being stripped away by the solar wind and lost to space. The Solar Wind Around Pluto (SWAP) instrument observed a cavity in the solar wind -- the outflow of electrically charged particles from the Sun -- between 77,000 km (48,000 miles) and 109,000 km (68,000 miles) downstream of Pluto. SWAP data revealed this cavity to be populated with nitrogen ions forming a “plasma tail” of undetermined structure and length extending behind the planet.

Pluto mountain range close-up image colorized and slightly sharpened

I took the recently published close-up of a mountain range on Pluto and colorized it using the color scheme from previous color images. Image is slightly zoomed in and sharpened.

Graphene quantum dots are environmentally-friendly and low-cost. They are also superior to CdS/CdSe quantum dots for biomedical applications including fluorescent markers for seeing inside cells. They can easily be functionalized and have remarkable low cell toxicity. These samples I produced using a new method with high quantum yield. These dots can also be made into QD-LEDs, thin-film solar cells and solar paint, also they are superor for improving fuel cells when used instead of platinum .

Boron-doped Graphene Quantum Dots (nanographene) show intense photolumenescence. I've been making similar quantum dots and exploring co-doping the dots with nitrogen as well for a broader color emission spectrum.

Our guidelines are to please have some references, can you point us to some of the research on this?
Thanks.

In the next 2015-2025 there will be nothing to forecast, the spread of innovating technology will be unstoppable by big companies, Wide access to the technical data and the resources will be beyond the  borders and any control, and people will have access to the internet freely or very cheap. And i well be no exception.
