So they can be better men. Traditionally, people undergo a bit of self-examination when faced with a potentially fatal rupture in their long-term relationship. Thirty-two-year-old Henry* admits that what he did was a little more extreme.
This interest is due to the rediscovery of high electrical conductivity. Amongst the family of conducting polymers and organic semiconductors, polyaniline has many attractive processing properties. Because of its rich chemistry, polyaniline is one of the most studied conducting polymers of the past 50 years.he emeraldine (n = m = 0.5) form of polyaniline, often referred to as emeraldine base (EB), is neutral, if doped (protonated) it is called emeraldine salt (ES), with the imine nitrogens protonated by an acid. Protonation helps to delocalize the otherwise trapped diiminoquinone-diaminobenzene state.
The structure of melanin provides absorption of potentially harmful radiation in the ultraviolet and visible light spectrum. The primary structure of eumelanin, for example, is a mixture of 5,6-dihydroxyindole, a related molecule called 5,6-dihydroxyindole-2-carboxylic acid and the oxidized forms of each.
