The effects of boron and sulfur impurities on the ideal cleavage fracture properties of Ni3Al under tensile stress are investigated using the full-potential linear-muffin-tin-orbital total-energy method, with a repeated slab arrangement of atoms simulating an isolated cleavage plane. Results for the stress-strain relationship, ideal cleavage energies, ideal yield stress and strains with and wit...

A 3D mechanically stable scaffold is shown to accommodate the volume change of a high-specific-capacity nickel-tin nanocomposite during operation as a Li-ion battery anode. The nickel-tin anode is supported by an electrochemically inactive conductive scaffold with an engineered free volume and controlled characteristic dimensions, which engender the electrode with significantly improved cyclabi...

A facile synthesis of potential acetylcholinesterase (AChE) inhibitors, the tacrine analogues 3a-p, has been accomplished by direct cyclocondensation of 1-aryl-4-cyano-5-aminopyrazole with β-ketoesters using tin(IV) chloride as catalyst. The structures of all the compounds have been confirmed by IR, ¹H- and ¹³C-NMR.

This paper proposed an integrated system between an eco-driving algorithm and an eco-signal control based on vehicle-to-everything (V2X) communication, and evaluated the system’s environmental benefits. The system calculates eco-speeds using vehicle information (e.g., current locations, vehicle speeds, and acceleration profiles) and signal information. In addition, the system controls current s...

The effects of TiN-ZrO₂ intermediate layer on the microstructures and magnetic properties of FePt films were investigated. The TiN-ZrO2 intermediate layer was granular consisting of grains of solid solution of Ti(Zr)ON segregated by amorphous ZrO₂. By doping ZrO₂ into TiN intermediate layer, the FePt grains became better isolated from each other and the FePt grain size was reduced. For 20 vol. ...

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...
