Bayesian optimization of crystallization processes to guarantee end-use product properties
(Universidad Nacional del Sur, 2020-04-01)
For pharmaceutical solid products, the issue of reproducibly obtaining their desired end-use properties depending on crystal size and form is the main problem to be addressed and solved in process development. Lacking a ...
Calcium oxalate crystal production and density at different phenological stages of soybean plants (Glycine max L.) from the southeast of the Pampean Plain, Argentina
(Wiley Blackwell Publishing, Inc, 2016-11)
Glycine max L. (soybean) is one of the major crops of the world. Although the process of biomineralisation has been reported in some organs of soybean, we now report the description and quantification of calcium oxalate ...
Gamma irradiated LDPE in presence of oxygen. Part I. Non-isothermal crystallization.
(Elsevier Science, 2013-08-06)
Non isothermal crystallization of low density polyethylene (LDPE) samples irradiated under three different atmospheres was analyzed. The used doses were between 33 and 222 kGy and the atmospheres content 0, 21 and 100% ...
Sedimentation analysis of columnar ice crystals in viscous flow regimes
(John Wiley & Sons Ltd, 2020-01)
The sedimentation process of columnar ice crystals was evaluated using data obtained by the lattice Boltzmann method. The data used correspond to columnar ice crystals with maximum dimension less than 100 μm and aspect ...
Crystallization behavior of random ethylene-butene copolymers modified with organic peroxide
(Elsevier Science, 2012-01-02)
The effect of molecular cross-linking on the crystallization of random ethylene-1-butene copolymers obtained from hydrogenation of model polybutadiene was studied by means of differential scanning calorimetry. The copolymers ...
Non-isothermal crystallization of PCL/CLAY nanocomposites
(VBRI Press, 2018-06-14)
In this work, Differential Scanning Calorimetry (DSC) was used to study the crystallization behavior of nanocomposites based on polycaprolactone (PCL) reinforced with organo-montmorillonite (C20A) and organo-bentonite ...
Non-isothermal crystallization of polyvinylalcohol-co-ethylene
(Springer, 2005-01)
Non-isothermal crystallization of polyvinylalcohol-co-ethylene with different ethylene contents was studied. Several models were used to predict the crystallization behavior of these materials under non-isothermal conditions ...
Growing Fe-Mn-Al-Ni single crystals by combining directional annealing and thermal cycling
(Elsevier Science SA, 2020-01)
In pseudoelastic alloys, a fine-grained microstructure implies restrictions on the propagation and shrinkage of the martensitic phase. Thus, the pseudoelastic effect is adversely affected. For this reason, thermomechanical ...
Crystallization of polycaprolactone-clay nanocomposites
(John Wiley & Sons Inc, 2008-09-05)
The isothermal crystallization process of polycaprolactone/clay nanocomposites was studied at several temperatures. The effects of the clay type (modified and unmodified) and clay content were analyzed. Bulk crystallization ...
