SUMMARY A general method for determination of the stability constants of complexes of crown ethers and related compounds with small organic molecules in polar solvents is described, based on an indirect polarographic procedure. Computerized evaluation of the data forms an essential part of the procedure. interest in the chemistry of crown ethers and related(More)
Understanding and leveraging user search behavior is increasingly becoming a key component towards improving web sites functionality for the health care consumer and provider. In this study we propose to leverage user search behavior to design user-tailored browsing interfaces to better support locating information in healthcare websites at the(More)
A procedure is proposed for the determination of malononitrile by differential pulse polarography in methanolic 0.1M tetraethylammonium iodide/0.001M tetramethylammonium hydroxide as the supporting electrolyte. In this medium malononitrile is chemically converted into an electroactive species. With close control of timing of the steps in the procedure the(More)
