ZnO nanostructures were synthesized by a proteic sol-gel method, using zinc nitrate hexahydrate and gelatin as precursors. Size shape evolution of achieved annealing temperature in the range 250-1000 ºC. The crystalline structure, morphology optical properties nanoparticles characterized X-Ray Diffraction (XRD), Raman Spectroscopy (RS), Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), Transmission (TEM), room Photoluminescence (PL). result structural characterization...
Hf and N incorporation in GeO<sub>2</sub> suppresses its volatilization further oxidation of the Ge substrate.
Utilizamos vídeos disponíveis na web que mostram testes de colisões automóveis para investigar as propriedades do impulso uma força. Este tema, pouco abordado em sala aula, possui, automóveis, possibilidade aplicação problemas reais e importantes a compreensão fenômenos presentes nosso cotidiano. Segundo os PCN+, o dispositivo airbag seria um excelente exemplo ilustrar impulso. Para investigação deste problema através vídeos, utilizamos software livre Tracker, onde determinamos físicas, tais...
This study aims to assess the effectiveness of water-based formulations featuring m-2HEAOL and talc particles in deep drawing applications. The coefficient friction (COF) was measured through bending under tension (BUT) tests, while interaction mechanism between protic ionic liquid (PIL) analysed using FTIR, XPS, TGA analyses. results indicate that formulation containing 8 wt% PIL 0.5 exhibited best lubricating performance. due oleate molecules with Mg found basal layer, which enhanced...
In this work it is presented a photophysical study of thin films based on excited-state intermolecular proton transfer dyes 2-(4'amino-2'-hydroxyphenyl)benzoxazole (AHPBO) and 2-(4'aminophenyl)benzoxazole (APBO). The studied were characterized by Raman Spectroscopy, Atomic Force Microscopy, as well Photoluminescence UV-Vis absorption spectroscopies. addition, theoretical calculations applied using Gaussian09 software to obtain vibrational frequencies, corresponding assignments its...
This paper presents the theoretical and experimental study regarding optical structural properties of 2-(5'-amino-2'-hydroxyphenyl)benzothiazole. In order to investigate potential application this dye in organic light-emitting diodes, a photophysical characterization film, solution solid state was performed. Aditionally, Raman infrared spectroscopies were also applied. The results compared with calculations achieved by Gaussian09 software.
