Use of slag/sugar cane bagasse ash (SCBA) blends in the production of alkali-activated materials
(2013-08-14)
Blast furnace slag (BFS)/sugar cane bagasse ash (SCBA) blends were assessed for the production of alkali-activated pastes and mortars. SCBA was collected from a lagoon in which wastes from a sugar cane industry were poured. ...
Electrical, structural and thermal properties of new conductive blends (PANICG) based on polyaniline and cashew gum for organic electronic
(2019-05-30)
The application of cashew gum, in particular the one which is abundant in northeastern Brazil, remains limited to the foods and pharmaceutics industry. In attempting to obtain further potentialities of the cashew gum (CG), ...
Volatile organic compounds detection by electrical sensors using polyalkylthiophene-based Langmuir-Blodgett films
(Springer, 2019-03-01)
Despite their environmental and health hazards, volatile organic compounds (VOCs) are present in our everyday life (e.g., fuels and solvents). Their detection is of paramount importance for environmental and occupational ...
Eumelanin thin films: Solution-processing, growth, and charge transport properties
(2013-08-21)
Eumelanin pigments show hydration-dependent conductivity, broad-band UV-vis absorption, and chelation of metal ions. Solution-processing of synthetic eumelanins opens new possibilities for the characterization of eumelanin ...
Intergranular properties of uniaxially pressed YBa(2)Cu(3)O(7-delta) ceramic samples
(SOC MEXICANA FISICA, 2010)
We performed measurements of electrical resistivity as a function of temperature, rho(T), in polycrystalline samples of YBa(2)Cu(3)O(7-delta) (Y-123) subjected to different uniaxial compacting pressures. We observed by ...
Dielectric spectroscopy on Bi3Zn2Sb3O14 ceramic: an approach based on the complex impedance
(Elsevier B.V., 2003-12-01)
The dielectric properties and loss of Bi1.5ZnSb1.5O7 a poor-semiconducting ceramic were investigated by impedance spectroscopy, in the frequency range from 5 Hz to 13 MHz. Electric measurements were performed from 100 to ...
Influence of Ar+ ion irradiation on the properties of plasma polymerized acetylene films
(Elsevier Science SaLausanneSuíça, 2000)
Auto-combustion synthesis as a method for preparing BiFeO3 powders and flexible BiFeO3/PVDF films with improved magnetic properties. Influence of doping ion position, size and valence on electric properties
(2022-06-01)
Bismuth ferrite (BiFeO3) powders were synthesized by auto-combustion method using glycine as a fuel. Doping ions of different valence were used to study the influence on electrical conductivity and ferroelectric properties. ...
Design of microstructure of zirconia foams from the emulsion template properties
(2013-01-14)
In this work, we investigate the correlations between structural and rheological properties of emulsified aqueous sol and the porous microstructure of monolithic zirconia foams, manufactured by the integrative combination ...
Electrical properties of cr/crn nano-multilayers produced by the unbalanced magnetron sputtering technique
(Universidad Nacional de Colombia Sede Medellín, 2011)
Chromium nitride (CrN) films have been applied to several steels as protective coatings against wear and corrosion due to their excellent mechanical properties and corrosion resistance, and in the electronic field these ...
