Size and surface effects in the magnetic order of CoFe2O4 nanoparticles
(Elsevier Science, 2015-03)
In this work, we have focused on the size dependence of the magnetic properties and the surface effects of CoFe2O4 nanoparticles synthesized by high-temperature chemical method with diameter d~2, 4.5, and 7 nm, with narrow ...
Integrating Multiple Techniques to Estimate Population Size of an Impacted Dusky Dolphin’s Population in Patagonia, Argentina
(Frontiers Media, 2020-05)
Successful conservation strategies require an accurate estimation of population size and this parameter is one of the most important factors that determine the rate of various evolutionary processes. In this study we ...

Rolling contact fatigue resistance of ductile iron with different nodule counts and matrix microstructures
(Elsevier Science Sa, 2006-07)
Thin wall ductile iron castings are being used in the industry as a way to improve the strength to weight ratio of machine parts. The high cooling rate, suffered by thin wall parts during the solidification process, promotes ...
Particle size distribution. Main definitions and measurement techniques
(Research Singpost, 2010)
The importance of the particle size distribution (PSD) of polymer latexes is first discussed; and definitions of differential / cumulative distributions and average diameters are presented. Main analytical techniques for ...
Size structure of Antarctic krill inferred from samples of Pygoscelid penguin diets and those collected by the commercial krill fishery
(Springer Verlag Berlín, 2021-02)
In the Antarctic Peninsula, during the chick-rearing period Adélie (Pygoscelis adeliae) and gentoo (P. papua) penguins feed primarily on Antarctic krill (Euphausia superba), which is also exploited by the commercial fishery. ...
Simple high-performance liquid chromatography-ultraviolet method to quantify the molecular size distribution of nonylphenol ethoxylates
(American Chemical Society, 2014-01-30)
Polyethoxylated nonylphenols (NPEOx) are widely used in various domestic and industrial applications. These commercial products are mixtures of oligomers that affect aquatic ecosystems, acting as endocrine disruptors. In ...
