Miller has also pointed out that the RNA bases are destroyed very quickly in water at 100 C—adenine and guanine have half lives of about a year, uracil about 12 years, and cytosine only 19 days. Levy, M and Miller, S.L., 1998. The stability of the

The use of amine as a base yielded a microporous material, while inorganic bases increased the pore volume by 50–70% and the pore diameter from 0.5 to 1.7 nm. Heating the xerogels results in a strong decrease of surface area to 20–80 m 2 g −1 at temperatures of 673–873 K due to the glow transition caused by crystallization of amorphous material into the anatase structure [ 90 , 91 ] .

Fossil fuel coustion and agriculture also produce increased atmospheric inputs of dissociation products of strong acids (HNO 3 and H 2 SO 4) and bases (NH 3) to the coastal and open ocean. These inputs are particularly important close to major source regions, primarily in the northern hemisphere, and cause decreases in surface seawater alkalinity, pH, and DIC ( Doney et al. 2007 ).
