Amorphous Bi2Pb0.6Sr2Ca2Cu3Ox obtained by melt-spinning and its superconductivity after crystallisation

Enhanced Hydrogen Storage Kinetics of Nanocrystalline and Amorphous Mg2Ni-type Alloy by Melt Spinning

Mg₂Ni-type Mg₂Ni1-xCox (x = 0, 0.1, 0.2, 0.3, 0.4) alloys were fabricated by melt spinning technique. The structures of the as-spun alloys were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The hydrogen absorption and desorption kinetics of the alloys were measured by an automatically controlled Sieverts apparatus. The electrochemical hydrogen storage kine...

Properties using metallic amorphous ribbons from (Fe-Co-Ni)- metalloid system, obtained by melt-quenching

A COMPARISON OF THE REPRODUCIBILITY AND HOMOGENEITY OF AMORPHOUS Cu-Zr ALLOYS PREPARED BY ROLLER-QUENCHING AND MELT SPINNING

Optimal Control of Melt Spinning Processes

An optimal control problem for a mathematical model of a melt spinning process is considered. Newtonian and non–Newtonian models are used to describe the rheology of the polymeric material, the fiber is made of. The extrusion velocity of the polymer at the spinneret as well as the velocity and temperature of the quench air serve as control variables. A constrained optimization problem is derive...

Soy matrix drug delivery systems obtained by melt-processing techniques.

The aim of this study was to develop new soy protein drug delivery matrix systems by melt-processing techniques, namely, extrusion and injection moulding. The soy matrix systems with an encapsulated drug (theophylline, TH) were previously compounded by extrusion performed at two different pH values, (i) pH 4 (SIpDtp) and (ii) pH 7 (SIDtp), and further injection-moulded into a desired shape. Dur...
