Electrochromic systems providing enhanced cycle lifetime. The increase in cycle lifetime is a product of one or more of the following: novel or known asymmetric viologen compounds, mixed electrolyte systems, and mixed solvent systems.

Enhanced cycle lifetime electrochromic systems

A method for the detection of nitrate esters using a solid working electrode of silver, copper, or gold. The method involves the forming of a test solution of a sample and supporting electrolyte, the insertion of the solution into a cell having the solid working electrode, deoxygenation of the test solution, application of a linearly varying potential to the cell and the recording of a voltammogram to show the reduction wave of the nitrate esters.

Detection of nitrate esters using silver electrode

A calcium electrode for an electrochemical cell with an electrolyte consing of molten nitrates and up to 10 mole percent halides.

Protected calcium anode

A method for lasing comprising preparing an aqueous solution of a member selected from the group consisting of 7-hydroxy-coumarin-8-methyleneiminobisacetic acid and the Ca.sup.++, Sr.sup.++, Ba.sup.++ and Al.sup.+++ complexes thereof and subjecting the solution to the energy provided by a laser.
