The temperature thawing, as called tempering, of triacylglycerols (TAGs) is an important processing method in food productions, such as chocolates, cream, confections, and spreads. Especially, melt-mediation by temperature thawing is famous in chocolate production for controlling the polymorphic crystalline forms and accelerating crystallization. In the present study, we investigated the α-melt...

A study utilizing isotactic poly(4-methyl-1-pentene) (PMP) was undertaken to investigate a three stage process (melt-extrusion/annealing/uniaxial-stretching) (MEAUS) employed to produce microporous films. The results of this study will be reported in the course of two papers. In this first part, three PMP resins were melt-extruded into tubular films (blowup ratio; BUR = 1), where the resins eac...

A numerical model is developed to describe the flow and heat transfer behavior of liquid metals in a cold delivery tube during gas atomization. Numerical calculations for liquid In, Sn, Bi, Pb, Zn and Sb are performed to investigate the influence of processing parameters and material properties on the flow and cooling of the liquid metals, and to predict the minimum melt superheat that is neces...

Highly porous poly (ϵ-caprolactone) microfiber scaffolds can be fabricated using electrospinning for tissue engineering applications. Melt electrospinning produces such scaffolds by direct deposition of a polymer melt instead of dissolving the polymer in a solvent as performed during solution electrospinning. The objective of this study was to investigate the significant parameters associated w...

Experimental and mathematical modeling analyses were used for controlling melt free-radical grafting of vinylic monomers on polyolefins and, thereby, reducing the disturbance of undesired cross-linking of polyolefins. Response surface, desirability function, and artificial intelligence methodologies were blended to modeling/optimization of grafting reaction in terms of vinylic monomer content, ...

High engineering critical current density JE of > 500A/mm 2 at 20T and 4.2K can be regularly achieved in Ag-sheathed multifilamentary Bi2Sr2CaCu2Ox (Bi-2212) round wire when the sample length is several centimeters. However, JE(20T) in Bi-2212 wires of several meters length, as well as longer pieces wound in coils, rarely exceeds 200A/mm. Moreover, long-length wires often exhibit signs of Bi-22...
