An alkaline primary Mg-air battery made from a porous Mg thin film displayed superior discharge performances, including a flat discharge plateau, a high open-circuit voltage of 1.41 V and a large discharge capacity of 821 mAh g(-1), suggesting that the electrochemical performances of Mg-air batteries can be improved by controlling the Mg anode morphology.

The formation of the icosahedral phase (I-phase) as a secondary solidification phase in Mg-Zn-Y and Mg-Zn-Al base systems provides useful advantages in designing high performance wrought magnesium alloys. The strengthening in two-phase composites (I-phase + α-Mg) can be explained by dispersion hardening due to the presence of I-phase particles and by the strong bonding property at the I-phase/m...

Vd or Volume of mg/dl will greatly elevate the calculated creatinine clearance. This is . (Use minimum SCr of 1 mg/dL.. (round dose to nearest 10 mg for gentamicin/ tobramycin and to nearest 50 mg for amikacin). A trough level should be obtained within 30 minute...

a r t i c l e i n f o a b s t r a c t Keywords: seawater chemistry Cenozoic climate global carbon cycle magnesium isotopes Cooling of Earth's climate over the Cenozoic has been accompanied by large changes in the magnesium and calcium content of seawater whose origins remain enigmatic. The processes that control these changes affect the magnesium isotopic composition of seawater, rendering it a...

Marine Mg-evaporites are a small oceanic sink of magnesium, precipitating only from extremely evaporated brines. The isotopic composition Mg in seawater, δ26Mgseawater, has recently been shown to be an effective tool for reconstructing the budget modern and past oceans. However, estimations isotope fractionation between their solution required full quantification effect evaporitic on as well ut...

We report the discovery of a new gravitationally lensed radio source. Radio maps of MG 0751+2716 show four lensed images, which, at higher resolution, are resolved into long arcs of emission. A group of galaxies is present in optical images, including the principal lensing galaxy, with a much brighter galaxy just a few arcseconds away. We have measured the redshift of this brighter galaxy. No o...
