This paper outlines our recent study on effects of cast film extrusion and biaxial orientation on the morphological development and dielectric performance of biaxially oriented polypropylene (PP) films based on two capacitor-grade isotactic PP (iPP) raw materials. Results on polymorphic composition, melting behavior, microstructure and dielectric properties are reported. Morphological developme...

Languages that provide polymorphism tend to place restrictions on object representations, separate compilation, and/or performance. For instance, most Ada implementations require that polymorphism be resolved before compilation. Consequently, separate compilation is sacriiced, since eliminating poly-morphism is a cross-module transformation. Some languages, like C++ and Modula-3, restrict the r...

We report the mechanism and scope of “preferential enrichment”, which is an unusual symmetry-breaking enantiomeric resolution phenomenon that is initiated by the solvent-assisted solid-to-solid transformation of a metastable polymorphic form into a thermodynamically stable one during crystallization from the supersaturated solution of certain kinds of racemic mixed crystals (i.e., solid solutio...

Febuxostat (FXT), a xanthine oxidase inhibitor, is an interesting and unique molecule, which exhibits extensive polymorphism, with over 15 polymorphic forms reported to date. The primary purpose of the study was to characterize the three polymorphic forms with respect to their thermodynamic quantities and establish thermodynamic relationship between them. The polymorphs were characterized by th...

We investigate the problem of multiplexing PCR for medical applications. We show that the problem is NP-complete by transformation to the Multiple Choice Matching problem and give an eecient approximation algorithm. We developed this algorithm in a computer program that predicts which genomic regions may be simultaneously ampliied by PCR. Practical use of the software shows that the method can ...

Solid-state M-4-MeO-Bz compounds, where M stands for trivalent La, Ce, Pr, Nd and Sm and 4-MeO-Bz is 4-methoxybenzoate, have been synthesized. Simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), X-ray powder diffractometry, infrared spectroscopy and complexometry were used to characterize and to study the thermal behaviour of these ...

Mantle-derived garnet peridotites are a minor component in many very high-pressure metamorphic terranes that formed during continental subduction and collision. Some of these mantle rocks contain trace amounts of zircon and micrometer-sized inclusions. The constituent minerals exhibit pre- and postsubduction microstructures, including polymorphic transformation and mineral exsolution. Experimen...

[1] Transformation superplasticity is a deformation mechanism that occurs during the phase transformation of an externally stressed material. Pressure-induced transformation superplasticity, which has long been postulated to occur in olivine in the Earth’s interior, is shown to take place in water ice. Pure ice specimens were subjected to hydrostatic pressure cycling between 0 and 300 MPa to re...
