The formation of [3M + Met]2+ ions has been studied using N-FMOC-proline methyl ester as a model organic ligand and Mg2+, Ca2+, Sr2+, Ba2+, Fe2+, Ni2+, Mn2+, Co2+ and Zn2+ chlorides or acetates as the sources of bivalent cation. It was found that all ions studied form [...
Hidden sources of allergy triggers are all around us. Indoor pollution Studies have shown that indoor air pollution is often at least twice as high as what you get outdoors. If you're staying inside with the windows shut to avoid pollen, you may not be helping your situation. The ...
