Pesquisadores da USP descobriram um novo mineral cujas propriedades físicas e estruturais o habilitam para importantes aplicações tecnológicas. O novo mineral foi encontrado em uma cavidade muito pequena de uma rocha de carbonatito, que é […]
FAST ONE-STEP SYNTHESIS AND SINTERING OF MATERIALS PROMOTED BY ELECTRIC FIELDS Functional dielectric materials have a wide range of applications in electro-electronic devices such as capacitors, oxygen sensors and varistors, frequently in the form of […]
Writers: Francisco W. B. Aquino, Caio M. Paranhos and Edenir R. Pereira-Filho Keywords: Polymer; Method Abstract: This study presents a procedure for direct Sb determination in solid e-waste samples (polymers). Polymer standards (acrylonitrile–butadiene–styrene (ABS) and polycarbonate (PC)/ABS) were mixed with dichloromethane […]
Strontium titanate is a perovskite structure material widely studied. The possibility of creation of oxigen vacancies in the structure of this compound , increase significatively their physical properties like: electric conductivity, physical stability and photoluminescence. […]
Os estudantes franceses da Institut Universitaire de Technologie (IUT) Saint Jerôme (Aix-Marseille University) Thomas Ayuste e Christian Gagliardi chegaram nesta semana ao CCMC para desenvolverem seus estágios de conclusão de curso, durante dois meses. Os […]
