Abstract: A phase change material composition for combined electrochemical and thermal energy storage is provided. The composition includes a salt hydrate, a polymeric stabilizer, a nucleating agent, and a thiosulfate salt hydrate. The salt hydrate is present in the composition in an amount of from 0.1 to 99 wt. %. The polymeric stabilizer is present in the composition in an amount of from 0.1 to 20 wt. %. The nucleating agent is present in the composition in an amount of from 0.1 to 20 wt. %. The thiosulfate salt hydrate is present in the composition in an amount of from 0.1 to 25 wt. %. A combined electrochemical and thermal storage system including the phase change material composition is further provided.

Abstract: The present invention provides compositions including polyelectrolyte complexes. The composition includes: 1) an inorganic salt comprising a metal ion having a charge of at least +1 and an anion having a charge of at least ?1; and 2) a complex comprising a first species and a second species, wherein the first species is a positively charged polymerizable monomer or a first charged polymer comprising one or more positively charged monomer repeat units; the second species is a negatively charged polymerizable monomer or a second charged polymer comprising one or more negatively charged monomer repeat units; and the complex has a net charge of near zero. These compositions are useful for ion selective applications in electrochemical devices.

Abstract: Methods and compounds effective in ameliorating conditions characterized by unwanted calcium channel activity, particularly unwanted N-type and/or T-type calcium channel activity are disclosed. Specifically, a series of compounds containing both an amino acid functionality and multiple aromatic rings are disclosed of the general formula (1) where X is benzhydryl, or an aromatic or heteroaromatic ring.
