Surface modification by metal ion implantation forming metallic nanoparticles in insulating matrix.
(Kusadasi, 2013-09-15)
There is special interest in the incorporation of metallic nanoparticles in a surrounding dielectric matrix for obtaining composites with desirable characteristics such as for surface plasmon resonance, which can be used ...

The gas metallicity gradient and the star formation activity of disc galaxies
(2016)
We study oxygen abundance profiles of the gaseous disc components in simulated galaxies in a hierarchical universe. We analyse the disc metallicity gradients in relation to the stellar masses and star formation rates of ...
Flow evolution of a metallic slurry during thixoextrusion of an automotive valve
(2004-12-01)
The aim of this work is to characterize a metallic slurry (Al-4.5%Cu) flow during thixoforming of an automotive valve. The necessary globular structure was obtained by first inoculating the alloy with TIBAL (5%Ti, 1%B, Al ...
Evidence for movement of heavy metals in a soil irrigated with untreated wastewater
(American Society of Agronomy, 1986)
A Vertisol irrigated for over five decades with an untreated municipal wastewater had elevated levels of DTPA extractable Cd, Co, Cu, Mn, Ni, and Zn in the cultivated layer of the soil as compared to lower layers. Total ...
Heavy metal distribution in the sediment profiles of the Sauípe River Estuary, north seashore of the Bahia State, Brazil
(2011)
The distribution of the elements Al, Fe and selected heavy metals (Pb, Zn, Cd, Cu and Cr) plus the organic matter in the sedimentary substratum of the mangrove ecosystem that surrounds the estuary of the Sauípe River (Bahia, ...
MATHEMATICAL MODELS AND POLYHEDRAL STUDIES FOR INTEGRAL SHEET METAL DESIGN
(SIAM PUBLICATIONSPHILADELPHIA, 2012)
We deal with the optimization of the production of branched sheet metal products. New forming techniques for sheet metal give rise to a wide variety of possible profiles and possible ways of production. In particular, we ...
Alteration of enzyme activities and functional diversity of a soil contaminated with copper and arsenic
(Elsevier, 2020)
Copper (Cu) mining has to address a critical environmental issue related to the disposal of heavy metals and metalloids (HMs). Due to their deleterious effects on living organisms, Cu and arsenic (As) have gained global ...
