Fullerene Ceo is an electron-deficient compound with rich photophysical and photochemical properties. Moreover, the triplet-excited state of Ceo is formed almost quantitatively and, in the presence of molecular oxygen, energy transfer from the triplet-excited...

Finally, oxygen is essential to all animal life on Earth. A person can survive a few days or weeks without food or water, but no more than a few minutes without oxygen. In the absence of oxygen, energy-generating chemical reactions taking place within cells would come to an end, and a person would die. 

Q.2.6 Does the endosymbiotic theory support the view that compartmentalization is causally related to (a) the surface-volume problem or (b) tlie oxygenation-energy catastrophe ...

Self-accelerating decomposition temperature (SADT) Organic peroxides or other synthetic chemicals that decompose at ambient temperature, or react to light or heat, resulting in a chemical breakdown. This releases oxygen, energy, and fuel in the form of rapid fire or explosion. To ensure stabilization, these materials must be kept in a dark or refrigerated environment. 

Intermolecular interactions of metal complexes can be seen by photophysical and photochemical measurements. Some metal complexes, such as Ru(bpy)3 " or Ru(II)-tris(4,7-diphenyl-l,10-phenanthroline) " , exhibit a high quantum yield and long life time of excited states, which is quenched by acceptors such as oxygen (energy transfer under formation of singlet oxygen) or (electron transfer and formation of methylviologen...
