High-purity iron pyrite (FeS2) nanowires as high-capacity nanostructured cathodes for lithium-ion batteries.
Iron pyrite is an earth-abundant and inexpensive material that has long been interesting for electrochemical energy storage and solar energy conversion. A large-scale conversion synthesis of phase-pure pyrite nanowires has been developed for the first time. Nano-pyrite cathodes exhibited high Li-storage capacity and excellent capacity retention in Li/pyrite batteries using a liquid electrolyte,...
متن کاملHigh purity amphotericin B.
OBJECTIVES Amphotericin B (AmB) is a drug of choice for treatment of disseminated fungal infections, but its use is often associated with severe adverse effects. Our observation that generic formulations of AmB contain multiple polyene components led us to propose that removal of other polyenes would yield a high purity AmB (AmBHP) with an improved therapeutic index. METHODS To test that prem...
متن کاملCatalytic enantioselective synthesis of chiral organic compounds of ultra-high purity of >99% ee
Shortly after the discovery of Zr-catalyzed carboalumination of alkynes in 1978, we sought expansion of the scope of this reaction so as to develop its alkene version for catalytic asymmetric C-C bond formation, namely the ZACA (Zr-catalyzed asymmetric carboalumination of alkenes). However, this seemingly easy task proved to be quite challenging. The ZACA reaction was finally discovered in 1995...
متن کاملLow Resistive Copper Thin Film Deposited with Ultra-high Purity Target and Ecr-ion Beam Sputtering
A thin film process using ECR-ion beam sputtering with ultra pure (99.999999%) copper target was investigated for improving transportation properties in the film. The electric resistivity of the thin film was 40% lower than that of using a commercial-grade purity target. And the optical qualities evaluated by the transmission and reflection spectrum measurements were also indicate slower relaxa...
متن کاملKawamata-viehweg Vanishing via Purity Properties of the Ultra-frobenius
Part 1 of this project is concerned with proving a relative version of the results in [1]. Consider the category of Lefschetz rings in which the objects are rings of equal characteristic zero which are realized as an ultraproduct of Noetherian rings of positive characteristic, and the morphisms between two such ultraproducts are given as ultraproducts of homomorphisms between the components. A ...
