Anionic water clusters have long been studied to infer properties of the bulk hydrated electron. In particular, the question of whether the excess electron is on the surface of the cluster or in the interior of the clusters has been the subject of much speculation. The successes of solid-state physics are built on exploiting the regularity of atomic arrangements in crystal. Describing the cryst...

Three distal imidazole pickets in a cytochrome c oxidase (CcO) model form a pocket hosting a cluster of water molecules. The cluster makes the ferrous heme low spin, and consequently the O(2) binding slow. The nature of the rigid proximal imidazole tail favors a high spin/low spin cross-over. The O(2) binding rate is enhanced either by removing the water, increasing the hydrophobicity of the ga...

In the title compound, [Cu(C(6)H(2)O(5))(H(2)O)(3)](n), an infinite chain is formed along [001] by linking of the Cu(OH(2))(3)O(4) cluster with one carboxyl-ate group of the furan-2,5-dicarboxyl-ate ligand. Adjacent chains are linked by O(water)-H⋯O hydrogen-bonding inter-actions. The Cu(OH(2))(3)O(4) cluster displays a penta-gonal bipyrimadal geometry with two weak coordinations [Cu-O(furan) =...

in this paper, productivity of and demand for water throughout eqlid’s sugar beet growers in 1385 were investigated. to address the objective 100 growers were selected using two-stage cluster sampling, then required dataset was obtained by interviewing and completing questionnaire. in order to study factors affecting sugar beet production, cobb-douglas production function was applied. based on ...

Anionic clusters comprising solvent molecules and excess electrons can provide new insights into electron solvation in liquids, an intrinsically bulk phenomenon. This paper reviews experimental and theoretical studies of this class of clusters, focusing primarily on water cluster anions, ðH2OÞ n , but also on iodide-water clusters, I (H2O)n, and methanol cluster anions ðCH3OHÞ n . Issues of par...

Ž . Ab initio embedded cluster calculations of water interaction with the TiO 110 surface predict that molecular adsorption 2 is more favorable than dissociative chemisorption. Unlike all previous calculations, this result is in agreement with recent temperature-programmed desorption and modulated beams experiments. Calculated surface relaxation, water adsorption energy and the densities of ele...

To assess links between betaproteobacterial ammonia-oxidizing bacteria (AOB) in marine sediment and in overlying water, communities in Loch Duich, Scotland, were characterized by analysis of clone libraries and denaturant gradient gel electrophoresis of 16S rRNA gene fragments. Nitrosospira cluster 1-like sequences were isolated from both environments, but different sequence types dominated wat...
