The tite compound, lithium penta-sodium nona-molybdate, LiNa(5)Mo(9)O(30), was synthesized by solid-state reaction. The three-dimensional [Mo(9)O(30)](6-) framework is built up from MoO(6) octa-hedra and MoO(5) bipyramids, linked together by edges and corners. The framework delimits two types of inter-secting tunnels running along [100] and [010] in which the Na(+) and Li(+) ions are located. T...

The atomic-scale structure of Bioglass and the effect of substituting lithium for sodium within these glasses have been investigated using neutron diffraction and solid state magic angle spinning (MAS) NMR. Applying an effective isomorphic substitution difference function to the neutron diffraction data has enabled the Na-O and Li-O nearest-neighbour correlations to be isolated from the overlap...

Kinetic and thermodynamic properties of red cell lithium (Li) efflux were examined in patients with essential hypertension; the maximal rate of Li efflux as affected by temperature was measured at the range of 12 degrees to 42 degrees C. Fifty-two patients with essential hypertension and 22 normotensives were studied. The mean Li efflux, both into sodium (Na) medium and Li-Na countertransport, ...

At present, the most promising alternative cathode material is sulfur due to its high theoretical capacity (1672 mAh g −1 ), low cost, high abundance in nature, and environmental benignity. [ 11–13 ] However, the rechargeable battery chemistry based on sulfur cathode still faces three intrinsic challenges: [ 14–19 ] (1) the formation of intermediate polysulfi de products and the parasitic shutt...

The phosphodiester linkage central to biological systems has been modeled by methyl phosphodiester (MPDE) in various theoretical and experimental studies. Under physiological conditions, hydrolysis of the phosphodiester is negligible, however this process can be catalyzed in the presence of metal ions. To understand the role of alkali metals in MPDE hydrolysis and, in particular, how it influen...

Probabilistic models have played an indispensable role in population genetics for close to a century. They provide a powerful lens through which one can investigate how various evolutionary forces interact and produce the intricate patterns of genetic variation in a population. Furthermore, through statistical inference, one can estimate evolutionary parameters from population genetic data and ...

1. It is shown that the NH(4) ion acts in cases of antagonism on the egg of Fundulus more like the K ion than the Na ion; this corresponds to the fact that in its general chemical behavior the NH(4) ion resembles the K ion more closely than the Na ion. 2. It is shown that the tolerance of sea urchin eggs towards the Li ion can be increased 500 per cent or more if at the same time a certain amou...

The McMurdo dry valleys of Antarctica represent the largest of the ice-free areas on the Antarctic continent, containing glaciers, meltwater streams, and closed basin lakes. Previous geochemical studies of dry valley streams and lakes have addressed chemical weathering reactions of hyporheic substrate and geochemical evolution of dry valley surface waters. We examine cation transport and exchan...
