Investigação da formação da fase óxido e estudo da influência da microestrutura e morfologia nas propriedades eletrocrômicas de filmes finos de Nb2O5.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2002-08-30)
Nb2O5 is known by your capacity of optical absorption variation, which it happens due
to reduction and small ions intercalation, such as Li+, double process. In this work, Nb2O5 electrochromic films were produced by Pechini ...
Thermal and solvatochromic effects on the emission properties of a thienyl-based dansyl derivative
(Royal Soc Chemistry, 2020-08-04)
Environmental conditions have a profound effect on the photophysical behavior of highly conjugated compounds, which can be exploited in a large variety of applications. In this context, we use a combination of experimental ...
Spectroelectrochemical Properties and Lithium Ion Storage in Self-Assembled Nanocomposites from TiO(2)
(AMER CHEMICAL SOC, 2010)
Layer-by-layer (LbL) nanocomposite films from TiO(2) nanoparticles and tungsten-based oxides (WO(x)H(y)), as well as dip-coating films of TiO(2) nano particles, were prepared and investigated by electrochemical techniques ...
Desenvolvimento de filmes finos poliméricos para aplicação em dispositivos fotovoltaicos orgânicos
(Universidade Federal de Minas GeraisUFMG, 2015-07-31)
This work presents the study of conjugated polymers and copolymers derivative from thiophenes, with promising properties to organic photovoltaic cells application (OPV). Initially, was realized the synthesis of the monomer ...
DNA-based ionic conducting membranes
(AMER INST PHYSICS, 2011)
Deoxyribonucleic acid based gel solid electrolytes were prepared and their electric properties were characterized. Their ionic conductivity is in the range of 10(-4)-10(-5) S/cm at room temperature and increases linearly ...
Electrical and electrochemical measurements in nanostructured films of polythiophene derivatives
(Elsevier B.V., 2015-05-20)
Thin films from polythiophene derivatives can be fabricated by some experimental methods, including the Langmuir techniques, which are particularly suitable if some degree of molecular control is required. In this study, ...
Electrolyte-Gated WO3 Transistors: Electrochemistry, Structure, and Device Performance
(2015-09-17)
Electrolyte-gated (EG) transistors, based on electrolyte gating media, are powerful device structures to modulate the charge carrier density of materials by orders of magnitude, at relatively low operating voltages (sub-2 ...
