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.
Betadine is a stable chemical complex of polyvinylpyrrolidone (povidone, PVP) and elemental iodine. It contains from 9.0% to 12.0% available iodine, calculated on a dry basis.This unique complex was discovered in 1955 at the Industrial Toxicology Laboratories in Philadelphia by H. A. Shelanski and M. V. Shelanski.uman clinical trials showed the product to be superior to other iodine formulations. Betadine was immediately marketed, and has since become the universally preferred iodine antiseptic. Betadine is only sold for the purpose of healing wounds, and not as an oral sore throat gargle, as widely thought.
