Alloy-type anodes such as silicon and tin are gaining popularity in rechargeable Li-ion batteries, but their rate/cycling capabilities should be improved. Here by making yolk-shell nanocomposite of aluminium core (30 nm in diameter) and TiO2 shell (B3 nm in thickness), with a tunable interspace, we achieve 10C charge/discharge rate with reversible capacity exceeding 650mAh g 1 after 500 cycles,...

Nanobelts are a new class of semiconducting metal oxide nanowires. The ribbon-like nanobelts are chemically pure and structurally u w c

The title polymeric mixed-organyl tin hydroxide, [Sn(C(6)H(5))(2)(C(6)H(11))(OH)](n), hass a hydroxide-bridged chain structure; the tin center shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The Sn atom lies on a special position of site symmetry m; the symmetry element relates one phenyl ring to the other and also relates one half of the cyclo-hexyl ring to the other half.

pattern has been devised :? An empty ghi tin is placed upright and cut across the top medially. A similar cut is made parallel across the front of the tin about three inches from the bottom and the cut extended up each side to meet the top cut, the part removed being shaped like a banker's shovel. A modified pattern is made by cutting perpendicularly through the top to within three inches of th...

Coaxial PANI/TiN/PANI nanotube arrays prepared by electrochemical polymerization of PANI on nanoporous TiN nanotube arrays exhibit a high specific capacitance of 242 mF cm(-2), excellent rate capability with the capacitance remaining at 69% when the current density is increased 50 times from 0.2 to 10 mA cm(-2), and a long cycling life with less than 0.005% decay per cycle.

We report the implementation of a fully relativistic time dependent density functional theory (TDDFT) method for carrying out x-ray absorption spectroscopy calculations for extended systems. This is the first time that a TDDFT simulation of x-ray absorption in extended systems has featured a full potential ground state calculation. We prove that this unusual feature of the TDDFT implementation ...

The first North American full scale post aerobic digester (PAD) is successfully operating at the Spokane County Regional Water Reclamation Facility (SCRWRF). The SCRWRF PAD has demonstrated ammonia removals of 90% or above without alkalinity or supplemental carbon addition. When operational controls were optimized for total inorganic nitrogen (TIN) removal, the SCRWRF PAD demonstrated effluent ...
