14. Transmissive to Dark Electrochromic and Fluorescent Device Based on Poly(fluorene-bisthiophene) Derivative
Films of a poly(fluorene-bisthiophene) derivative, named PFBT, were electrodeposited onto indium tin oxide (ITO) electrodes and their electrochromic and fluorescence properties were investigated. Such films displayed color variation from yellow, in the neutral state, to green, in the oxidized state, as shown by tracking of the CIE (Commission Internationale

18. Effects of gamma radiation on the stability and degradation kinetics of phenolic compounds and antioxidant activity during storage of (Oryza sativa L.) black rice flour
Abstract The effects of gamma radiation (0, 1, 2 and 3 kGy) were used to evaluate the stability and thermal degradation kinetics of anthocyanins, as well as the stability of total phenolic compounds (TPC) and antioxidant activity at different temperatures (4, 25, 35 and 45 °C) during the storage (0, 30, 60, 90 and 120 days) of black rice flour. This flour c

21. Dispositivo para estudo de ressonância e elasticidade em hastes cilíndricas
Resumo Neste artigo propomos um dispositivo para demonstrações em sala de aula de ressonância em hastes cilíndricas. O dispositivo consiste em um aro com hastes de diferentes comprimentos ligado a uma fonte de vibração. Alterando-se a frequência de vibração, as hastes entram em ressonância, permitindo uma análise qualitativa dos modos de vibraçã

23. Identification of Humidity Sensing Mechanism in MgAl2O4 by Impedance Spectroscopy as Function of Relative Humidity
MgAl2O4 is a humidity sensing material, which high melting point requires high sintering temperatures. In this work, manganese oxide was used as a sintering aid to obtain MgAl2O4 samples sintered at 1350°C with a microstructure suitable for humidity sensing. Impedance spectroscopy analyses were performed at several levels of relative humidity, indicating th

24. Improvement of power efficiency of hybrid white OLEDs based on p-i-n structures
ABSTRACT In this article, hybrid white organic light-emitting diodes (WOLEDs) under p-i-n structures have been investigated in terms of power efficiency. By using tris(8-hydroxy quinolinato) aluminum (Alq3) doped with 8-hydroxy-quinolinato lithium (Liq) as an n-type and WHI112 doped with molybdenum trioxide (MoO3) as a p-type, the typical device structure of
