Aftereffects of the Tsunami. Rikuzentakata was once a vibrant fishing port, a place of people, temples and traditional houses and was listed as one of Japan's most scenic places.
Love County, Oklahoma -- Fishermen in a small community in southern Oklahoma are looking for answers after finding thousands of dead fish on the Red River.
Researchers at Notre Dame have developed a paste of semiconducting nanoparticles called solar paint (or "Sunbelievable") that could lead to easier-to-produce solar cells.
First, they mix t-butanol, water, cadmium sulfide and titanium dioxide
for 30 minutes. Next, they mask off a clear electrode with office tape.
Once the tape is in place, they spread the mixture onto the electode and
then anneal it with a heat gun. Finally, they sandwich an electrolyte
solution between the new electrode and a graphene composite electrode.
And then, it's time for testing under a beam of artificial light.
The best performing cell paint's light-to-electricity efficiency is 1% so far. The
efficiencies of commercial silicon solar cells are usually between 10
and 15%. The paints’ efficiencies, although low, are “quite decent” for a first-generation material. Read more: cen.acs.org
