Photoacoustic and transmission studies of SiC polytypes
(2003)
The optical bandgap energies (OBGE) of 3C, 15R, 6H and 4H-SiC have been investigate experimentally by transmission and photoacoustic spectroscopies. The measurements were performed on 470 mm thick wafers. The OBGE obtained ...
Photoacoustic and transmission studies of SiC polytypes
(ABM, ABC, ABPol, 2003)

Spectroscopy studies of 4H-SiC
(2003)
Calculations of the total dielectric functions and the optical bandgap energy (OBGE) of 4HSiC were performed by the full-potential linear muffin-tin-orbital method. The results are compared to spectroscopic ellipsometry ...
Desempenho tribológio de compósitos autolubrificantes em regime de lubrificação mista
(2020)
Atualmente, uma das grandes tendências mundiais se concentra no desenvolvimento de lubrificantes mais amigáveis ao meio ambiente e a saúde humana, principalmente através da redução ou até mesmo eliminação dos aditivos ...

Origin, development, and function of colored inguinal and axillary spots in cryptic lineages of poison frogs (Amphibia: Anura: Dendrobatoidea)
(Universidad de los AndesDoctorado en Ciencias - BiologíaFacultad de CienciasDepartamento de Ciencias Biológicas, 2022-07-28)
The study of biological models exhibiting dual cryptic-aposematic anti- predatory strategies based on their coloration, can shed important light on some of the great controversies in the evolution of aposematism. Among ...
