Temperature-Scanning Method for the kinetic studies of CO oxidation over ceria-zirconia supported gold catalysts
(ELSEVIER SCIENCE SA, 2015-12-15)
The experimental data of CO oxidation over the series of 2 wt.% Au/Ce1-xZrxO2 (x=0, 0.25, 0.5, 0.75, 1) catalyst were analyzed using a variation of the Temperature Scanning Method with the aim of catalyst's composition ...
Somatic cell count obtained by ekomilk scan® and correlations with other methods of analysisContagem de células somáticas obtidas pelo equipamento Ekomilk Scan® e suas correlações com outros métodos de análise

The study aimed to evaluate the equipment Ekomilk Scan® as an alternative to somatic cell count (SCC) in milk. For this individual cow milk samples of various ages and different stages of lactation in northeastern state ...
Low-temperature synthesis of nanosized bismuth ferrite by the soft chemical method
(2013-01-01)
This paper describes research on a simple low-temperature synthesis route to prepare bismuth ferrite nanopowders by the polymeric precursor method using bismuth and iron nitrates. BiFeO 3 (BFO) nanopowders were characterized ...

Assessment of the quality of heated oils by differential scanning calorimetry
(AMER CHEMICAL SOC, 1998)
Differential scanning calorimetry (DSC) was used to follow changes in the thermal characteristics of commercial frying oils (sunflower seed, colza, and groundnut) during heating at 180 degrees C for up to 10 h. DSC tracings ...
The synergistic effects of Nb/Mn and Sb/Mn on the microstructure and electrical characteristics of BaTiO3 based ceramics
(2005-08-22)
The microstructure and dielectric properties of Nb-Mn or Sb-Mn codoped BaTiO3 compositions were investigated. Starting ceramics powders were prepared by Pechini method. The composites were sintered at 1310°C and 1330°C in ...
