Internal Conversion in the Photosynthetic Mechanism of Blue-green Algae

1. In Chroococcus a quantum of light absorbed by phycocyanin has 90 per cent the chance of doing photosynthesis that a quantum absorbed by chlorophyll has. 2. By a process analogous to internal conversion in radioactivity (but with the linear dimensions and the wave length 10(4) times larger) there will be transferred from phycocyanin to chlorophyll See PDF for Equation (a number of the order o...

Boric Acid: As a Green Catalyst for the Conversion of Aldehydes and Ketones to Gem-Dihydroperoxides Using Aqueous 30% H2O2

Gem-dihydroperoxides as nearly stable peroxidic derivatives of aldehydes and ketones are known important intermediates in synthesis of anti-malaria drugs. Also, because containing high concentration of peroxidic oxygen, recently, some of these compounds have been used as solid, efficient and powerful oxidants in many oxidation organic reactions. Generally, these compounds are synthesiz...

Electrochemically-Driven and Green Conversion of SO2 to NaHSO4 in Aqueous Solution

The world has widely resorted to fossil fuels to power the industry and everyday life. In China, above 70% of the energy is extracted from coal. Emission of SO2 due to burning of fossil fuels, in particularly of coal, causes harmful impacts on the environment, human health, livestock, and plants (1,2). Many measures have been taken to cut off the emission of SO2 during the last generations. It ...

Green conversion of graphene oxide to graphene nanosheets and its biosafety study

Chemical reduction of graphene oxide (GO) to graphene employs the use of toxic and environmentally harmful reducing agents, hindering mass production of graphene which is of tremendous technological importance. In this study we report a green approach to the synthesis of graphene, bio-reduced by crude polysaccharide. The polysaccharide reduces exfoliated GO to graphene at room temperature in an...
