Long Cycle-Life Ca Batteries with Poly(anthraquinonylsulfide) Cathodes and Ca-Sn Alloy Anodes.

Calcium (Ca) batteries are attractive post-lithium battery technologies, due to their potential to provide high-voltage and high-energy systems in a sustainable manner. We investigated herein 1,5-poly(anthraquinonylsulfide) (PAQS) for Ca-ion storage with calcium tetrakis(hexafluoroisopropyloxy)borate Ca[B(hfip) ] [hfip=OCH(CF ) ] electrolytes. It is demonstrated that PAQS could be synthesized in a cost-effective approach and be processed environmentally friendly into the electrodes.

Utilization of a Medicaid-funded intervention for children with autism.

Objective: The study examined utilization of Wisconsin's Medicaid funding for autism intervention before and after a major shift in program administration.

Methods: Medicaid enrollment data were analyzed for 1,822 children with autism from 2000 through 2006, as were geocoded demographic data and decennial census data. Enrollees' data were compared with demographic data for Wisconsin's general population.
