High- versus Low-Spin Ni~(2+) in Elongated Octahedral Environments: Sr2NiO2Cu2Se2, Sr2NiO2Cu2S2, and Sr2NiO2Cu2(Se_(1-x)Sx)2Sr2NiO2Cu2Se2, comprising alternating [Sr2NiO2]~(2+) and [Cu2Se2]~(2-) layers, is reported... RD Smyth,JN Blandy,Z Yu - 《Chemistry of Materials ...
Theory suggests that the determinants of growth at low and high income levels may be different. If countries struggle to transition from growth strategies that are effective at low income levels to growth strategies that are effective at high income levels, they may stagnate at some middle income...
A sulfur-vulcanizable rubber compound having high modulus and low hysteresis properties. Such compounds comprise from about 0 to 65 parts by weight of polyisoprene; from about 25 to 35 parts by weight of a high styrene resin, SBR masterbatch and from about 0 to 65 parts by weight of poly...

A high-low base including a lower frame member supported upon a floor, an upper frame member, and an elevation assembly for variably elevating the upper frame member in height above the lower frame member, fits completely under, and within the pedestal base, of a conventional contour bed. A...
The frequency difference of the two lasers, and the injected light intensity is chosen so that the second laser does not lock onto the first laser freewheeling frequency. Preferably the first laser is of the ECL type, while the second laser is of the DFB type. Typically a photoelectric ...
