The in situ formation of gold nanoparticles in soda lime silicate glass under constant x-ray irradiation is compared with the ex situ formation in preirradiated glasses. The ASAXS measurements confirm that pure Au particles are formed. The comparison shows that the number of particles nucleated under irradiation is about an order of magnitude higher than of those nucleated with preirradiation. ...

Thick matrices of fibrinogen with incorporation of a matrix metalloproteinase inhibitor were covalently bonded on functionalized silicon surfaces using an ethyl-3-dimethyl-aminopropyl-carbodiimide and N-hydroxy-succinimide affinity ligand coupling chemistry. The growth of the structure was followed in situ using dynamic ellipsometry and characterized at steady-state with spectroscopic ellipsome...

Formation of hydroxylapatite through the precipitation and evolution of calcium phosphate precursor phases under varying conditions of temperature (25–90 °C), pH (6.5–9.0), and calcium to phosphorus ratio (1.0, 1.33, 1.5, and 1.67) comparable to those found in many sediments and soils were studied. The products of low-temperature precipitation were analyzed by ex situ X-ray diffraction and SEM,...

The hydrogen effect on a X65 carbon steel was investigated by tensile tests under both ex-situ and in-situ charging conditions. fractured samples were characterized compared using combination of scanning electron microscopy, backscattering diffraction, energy-dispersive spectroscopy. work highlights that the is necessity for investigation detrimental effects studied material, where pronounced r...

Recently, the applications of transmission electron microscopy (TEM) related techniques have extended from ex situ nanoscale characterization of structure and chemistry of products to dynamic measurements of nanostructures during reaction processes. Commercially available modified TEM specimen holders and TEM columns are being routinely employed to follow the structural and chemical changes at ...

an ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (vigna unguiculata, gossypium hirsutum, jatropha curcas, etc.) was conducted on magnesite mines which had above permissible levels of cadmium and lead. there was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...

Microbial communities associated with deep-sea corals are beginning to be studied in earnest and the contribution of the microbiome to host organismal function remains to be investigated. In this regard, the ability of the microbiome to adjust to prevailing environmental conditions might provide clues to its functional importance. In this study, we characterized bacterial community composition ...
