Nanoscale origins of super-capacitance phenomena
(Journal of Power Sources, 2019-02-28) [Resenha]
We review the origins of capacitive phenomena at the nanoscale to demonstrate that electrochemistry cannot be understood without a critical re-reading of nanoscale electronics, and vice-versa. The fundamentals are stated ...
Piezoresponse force microscopy characterization of rare-earth doped BiFeO3 thin films grown by the soft chemical method
(Ceramics International, 2013-04-01) [Resenha]
The multiferroic behavior with ion modification using rare-earth cations on crystal structures, along with the insulating properties of BiFeO3 (BFO) thin films was investigated using piezoresponse force microscopy. ...
Rietveld analyses and piezoelectric properties of niobium doped bismuth titanate systems
(Journal of Advanced Microscopy Research, 2010-08-01) [Resenha]
Bi 4Ti 3- xNbxO 12 (BITNb) samples, with × ranging from 0 to 0.40 were obtained using a polymeric precursor solution. Rietveld analyses confirmed that the powders crystallize in an orthorhombic structure free of secondary ...
Rietveld analysis of CaCu3Ti4O12 thin films obtained by RF-sputtering
(Journal of Materials Science: Materials in Electronics, 2016-03-01) [Resenha]
Calcium copper titanate, CaCu3Ti4O12, CCTO, thin films with polycrystalline nature have been deposited by RF sputtering on Pt/Ti/SiO2/Si (100) substrates at a room temperature followed by annealing at 600 °C for 2 h in a ...
Graphene-based protein biomarker detection
(Bioanalysis, 2015-01-01) [Resenha]
An ability to detect and quantify protein molecules, harbingers of specific pathologies, potentially underpins both early disease diagnosis and an assessment of treatment efficacy. However, the specific detection of a ...
Photoluminescence of BaZrO3 explained by a order/disorded transformation
(Journal Of Materials Science-materials In Electronics, 2015-04-01) [Resenha]
A hydrothermal (HTMW) microwave method was used to synthesize ordered-disordered BaZrO3 (BZ) nanoparticles at temperature of 140 A degrees C with times ranging from 15 min to 2 h. X-ray diffraction results verified the ...
