Formation of Cu-rich Nanoprecipitates in Cu Containing Pearlitic SGI
(American Foundry Society, 2020-11-29)
The presence of Cu-rich nanoprecipitates in a pearlitic spheroidal graphite (ductile) cast iron alloyed with 0.82 wt%Cu was studied. The size and distribution of the precipitates were examined by transmission electron ...
Nanoparticles obtained by confined impinging jet mixer: poly(lactide-co-glycolide) vs. Poly-ε-caprolactone
(Taylor & Francis, 2018-06)
This paper is focused on the production and characterization of polymeric nanoparticles obtained by nanoprecipitation. The method consisted of using a confined impinging jet mixer (CIJM), circumventing high-energy equipment. ...
Exact solution of the hydrodynamic focusing driven by hydrostatic pressure
(Springer Heidelberg, 2020-02)
Microfluidic nanoprecipitation makes use of hydrodynamic focusing (HF) to accurately control the diffusive mixing of reactants. Both stability and precise handling of flow streams are essential for this application. However, ...
Nanoprecipitation effects on phase stability of Fe-Mn-Al-Ni alloys
(Elsevier Science SA, 2017-02)
Early stages of coherent precipitation have been studied in several Fe-Mn-Al-Ni samples aged at 200 °C for different time intervals in order to analyze the effect of nanoprecipitation on the phase stability during thermally ...
The effect of gravity on microfluidic flow focusing
(Elsevier Science Sa, 2020-03)
Flow focusing is a key operation in microfluidics, involving applications that range from flow cytometry to nanoprecipitation on chips. Attaining a rational control of the width of the focused stream has been a concern ...
Gravity driven flow for the precise control of hydrodynamic focusing
(Universidad Nacional de Córdoba, 2019)
Hydrodynamic focusing is a key operation in microfluidics, withapplications that range from cell sorting and counting to mixing and reactions.For most of these operations, both stability and precise handling of thefocused ...
Effect of the precipitates on the thermodynamics of the martensitic transformations in Ti-rich Ni-Ti-Co thin films
(Elsevier Science, 2020-03)
The wide-spread multiple transformation in Ti-rich Ni-Ti shape memory alloys produced by Ti2Ni nano-precipitates was investigated. For this purpose, a series of amorphous Ti-Ni-Co thin films with the same composition were ...
Vortex dynamics in phase separated Tl0.58Rb0.42Fe1.72Se2 crystals
(Pergamon-Elsevier Science Ltd, 2016-12-01)
We report the critical current density Jc and the vortex dynamics in phase-separated Tl0.58Rb0.42Fe1.72Se2 crystals by performing magnetization measurements. Structural investigation reveals micro- and nanoscopic phase ...
A short review on the interaction of precipitates and martensitic transitions in CuZnAl shape memory alloys
(World Scientific, 2017-02-02)
The main effects of γ non-equilibrium nanoprecipitates in CuZnAl shape memory alloys are briefly reviewed. Aspects related to the nucleation and growth of precipitates are commented on and their effect on stress induced ...
