Lithium iodide

Lithium iodide, or LiI, is a compound of lithium and iodine. When exposed to air, it becomes yellow in color, due to the oxidation of iodide to iodine. It crystallizes in the NaCl motif. It can participate in various hydrates.

Applications

Lithium iodide is used as an electrolyte for high temperature batteries. It is also used for long life batteries as required, for example, by artificial pacemakers. The solid is used as a phosphor for neutron detection. It is also used, in a complex with Iodine, in the electrolyte of dye-sensitized solar cells.

In organic synthesis, LiI is useful for cleaving C-O bonds. For example it can be used to convert methyl esters to carboxylic acids:

Similar reactions apply to epoxides and aziridines.

Lithium iodide was used as a radio contrast agent for X-ray computed tomography imaging studies. Its use was discontinued due to renal toxicity, replaced by organic iodine molecules. Inorganic iodine solutions suffered from hyperosmolarity and high viscosities.

    The Legal Information Institute (LII) is a non-profit, public service of Cornell Law School that provides no-cost access to current American and international legal research sources online at law.cornell.edu. The organization is a pioneer in the delivery of legal information online. Founded in 1992 by Peter Martin and Tom Bruce, LII was the first law site developed on the internet. LII electronically publishes on the Web the U.S. Code, U.S. Supreme Court opinions, Uniform Commercial Code, the US Code of Federal Regulations, several Federal Rules, and a variety of other American primary law materials. LII also provides access to other national and international sources, such as treaties and United Nations materials. As of 2014, it had 18 million unique visitors per year.

    Since its inception, the Legal Information Institute has inspired others around the world to develop namesake operations. These services are part of the Free Access to Law Movement.

    History

    LII was established in 1992 at Cornell Law School by Professor Peter Martin and Tom Bruce with a $250,000 multi-year startup grant from the National Center for Automated Information Research. The LII was originally based on Gopher and provided access to United States Supreme Court decisions and the US Code. Its original mission included the intent to "carry out applied research on the use of digital information technology in the distribution of legal information,...[and t]o make law more accessible." In the early years of LII, Bruce developed Cello the first web browser for Microsoft windows. Cello was released on 8 June 1993. In 1994 LII moved from Gopher to the Web. Since 2007 the IRS has distributed its IRS Tax Products DVD with LII's version of 26 USC (Internal Revenue Code).
