A drug electrode assembly usefully employed in an electrotransport device for the delivery of drugs across a tissue surface includes an electrode, a drug reservoir which stores the drug (including an ionized (e.g., anionic) or neutrally charged drug species), and a liquid impermeable solid-state assist ion conducting barrier layer interposed between the electrode and the drug reservoir. The barrier layer can be a single-ion conductor of a specific (unique) species of ion called the assist ion. During drug delivery, the assist ion moves across the barrier layer into or out of the drug reservoir, and as the assist ion crosses the barrier layer / drug reservoir interphase, the drug species moves to the tissue surface. The assist ion can be, for example, sodium ions (Na+), and the electrode can be an electrode of the assist ion (i.e., a sodium electrode).

Photocurable or thermally curable thiosulfate-containing polymers have a Tg of at least 50° C. and (a) recurring units comprising pendant thiosulfate groups, and (b) recurring units comprising organic charge balancing cations that are associated with the (a) recurring units sufficiently to provide a net neutral charge with the pendant thiosulfate groups. These polymers can be represented by the following Structure (III):wherein R represents the organic polymer backbone, G is a single bond or a divalent linking group, M+ represents the organic charge balancing cation, and “a” represents at least 0.5 mol % and up to and including 50 mol % of (a) recurring units, and “b” represents the (b) recurring units and is at least equal to the “a” mol %, based on the total recurring units. These thiosulfate-containing polymers can be used to made dielectric compositions and gate dielectric layers in various devices.

The invention provides a nitrogen-containing double-tooth heterocyclic ring substituted tetrazole type rare-earth complex LnL3 expressed by the formula I, wherein Ar is a nitrogen-containing double-tooth heterocyclic ring; the center rare-earth ion Ln is any one of yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. The preparation method of the nitrogen-containing double-tooth heterocyclic ring substituted tetrazole type rare-earth complex LnL3 is characterized in that a nitrogen-containing double-tooth heterocyclic ring substituted tetrazole type three-tooth compound, namely a dipyridyl tetrazole type three-tooth compound or phenanthroline tetrazole type three-tooth compound, is taken as a single ligand, and simultaneously, coordination saturation is satisfied, and the tetrazole group in the complex serves as negative irons to realize electrically neutral charge balance together with center rare-earth metal cations. The obtained rare-earth complex is high in thermal stability, can be prepared into a device through an evaporation film-forming process or a solution film-forming process. Besides, the preparation method has the advantages of high yield, of the product has high purity, reaction time is short and operation is simple; and as a result, the cost is greatly reduced.

The invention discloses a magnetoelectric composite gas purification method. The method comprises a particulate matter deflection collection mode, a polarity separation collection mode and a common discharge collection mode, and comprises the following operation steps of 1, entering the particulate matter deflection collection mode, and detecting whether a large number of positively-charged and / ornegatively-charged particles exist in airflow or not; 2, if the large number of particles with positive electricity and / or negative electricity exist / exist, entering the polarity-divided collection mode, and if not, entering the common discharge collection mode, wherein the two collection modes both adopt a concentration sensor feedback adjustment method to determine the discharge voltage and / orthe number of corona wires. The method can detect and judge whether the aerosol particles have charges or not and the approximate proportion of the particles with positive charges, negative charges and neutral charges, and selects the proper collection mode, so that the effects of improving the dust removal efficiency, reducing the use power consumption and reducing the volume of the purifier areachieved.
