摘要:
An electrochemical cell for applications such as electrochemical fuel cells, or electrochemical cell gas sensors used for detection of target gas species in environments containing or susceptible to presence of same. The electrochemical cell utilizes an ionic liquid as an electrolyte medium, thereby achieving a broader range of operational temperatures and conditions, relative to electrochemical cells utilizing propylene carbonate or other conventional electrolytic media.

摘要:
Method and apparatus for electrochemical generation of quaternary ammonium hypohalite salts, which may be combined with the capabilities of free chlorine to form a novel biocidal system. An aqueous solution preferably comprising dissolved quaternary ammonium halide salts is electrolyzed, which converts the halide component of the quaternary ammonium salt to the corresponding halogen. The halogen dissolves in the aqueous solution producing hypohalous acid and hypohalite anion. A combination of one or more quaternary ammonium compounds and a halide salt, surfactant, and/or germicide may be electrolyzed. The solution may be incorporated into a delivery system for example, a spray bottle or hand sanitizer, or as part of a dispensing system whereby quaternary ammonium halide salts absorbed onto wipes can be dispensed as quaternary ammonium hypohalite salts.
摘要:
Aromatic non-polymeric amic acid salts are designed to be thermally converted into corresponding arylene diimides. These aromatic, non-polymeric amic acid salts can be used to prepare semiconducting thin films that can be used in various articles including thin-film transistor devices that can be incorporated into a variety of electronic devices. In this manner, the arylene diimide need not be coated but is generated in situ from a solvent-soluble, easily coated aromatic, non-polymeric amic acid salt at relatively lower temperature because the cation portion of the amic acid salt acts as an internal catalyst.
