We report on the evolution of a hollow sphere secondary structure of spherical nanoparticles by a solubilization-reprecipitation mechanism based on the difference of solubility products (K(sp)) of two different precipitates. Carbon-coated nanoparticles of olivine structure LiFePO(4) served as the primary nano-blocks to build the secondary nano-architecture.

the sargaz granitic intrusion has been emplaced in sargaz ophiolitic suite, south-east of sanandaj-sirjan metamorphic zone, south of kerman province. the central part of the intrusive body contains pinkish coarse-grained granite, but the fractured northern part, neighboring chah-mazraeh fault, has been subjected to pervasive na-metasomatism and related subsolidus reactions. in the northern alte...

Studies of the dC of pore water dissolved inorganic carbon (dC-DIC) were carried out in shallow water carbonate sediments of the Great Bahamas Bank (GBB) to further examine sediment–seagrass relationships and to more quantitatively describe the couplings between organic matter remineralization and sediment carbonate diagenesis. At all sites studied dC-DIC provided evidence for the dissolution o...

The macro-scale distribution of secondary precipitates in friction-stir-welded 2519 aluminium alloy was studied. It found that precipitation pattern essentially varied within the stir zone terms volume fraction, size, and even preferential concentration particles, either at grain boundaries or interior. This effect attributed to local variations welding temperature cooling rate, which led compl...
