Abstract

Analysis of the influence of acclimation temperature on kinetic properties of acid phosphatase and 5'-nucleotidase in carp muscle microsomes shows that acclimation temperatures alter the kinetic properties and the fatty acid and lipid composition in the muscle microsomes. The saturated fatty acid and cholesterol levels are higher in microsomes with 32 degrees Celsius than in those with 10 degrees Celsius acclimation temperature. The changes in lipid composition thus correlate to the variations in the kinetic properties of 5'-nucleotidase.

205. Enhancing the Potential of Light Perovskites: A Study on Fe-Doped CaTiO3Compounds for Advanced Technological Applications

Author

Barbieri, F., Dias, L. C., Endo, K. M., Mazur, M., Rosso, J. M., Tominaga, T. T., Bonadio, T. G. M., Dias, G. S., Ferrreira., A. C., Silva, D. M., Cótica, L. F., Santos, I. A., Eiras, J. A., and Freitas, V. F.

Abstract

This study explores the synthesis and characterization of Fe-doped CaTiO3compounds via the Pechini method, focusing on their structural, magnetic, and electrical properties. Notably, a previously unreported magnetic property is observed in the Fe-doped CaTiO3compound. Despite significant structural distortions, ferroelectric polarization is identified using the Geometrical Polarization Approach (GPA), indicating its emergent nature. These distortions are attributed to robust chemical bonds between ionic O1−2and Ti+4sites, as evidenced by electronic density maps. This research sheds light on the potential of these materials for various technological applications.

Abstract

An investigation of the magnetic-field, temperature and field-angle dependencies of critical current densities in high quality Bi2Sr2Ca2Cu3Ox thin films with c-axis orientation is presented. This involved the utilization of a metalorganic chemical vapor deposition technique for the preparation of the samples which were characterized by an x-ray diffractometer. Results indicated that the anisotropy of the films are caused by its crystal structure.

211. Critical current density of high-quality Bi2Sr2Ca2Cu3Ox thin films prepared by metalorganic chemical-vapor deposition

Abstract

The critical current densities of high-quality as-deposited c-axis oriented Bi2Sr2Ca2Cu3Ox thin films grown by chemical vapor deposition were investigated. The results showed that the films had smooth surfaces and exhibited no indications of any weak links in the critical current density behavior. The high critical current density observed in the field parallel to the a-b plane decreased sharply with the magnetic-field component in the c-direction.
