Synthesis and characterization of magnetite nanoparticles via the chemical co-precipitation method
Karat Petcharoen,Anuvat Sirivat +1 more
TL;DR: In this article, the size of the magnetite nanoparticles was carefully controlled by varying the reaction temperature and through surface modification, which significantly affected the particle size, the electrical conductivity, and the magnetic properties.

Imaging distribution of local stiffness over surfaces using atomic force acoustic microscopy
TL;DR: In this article, the authors report a systematic study to determine local elastic properties of surfaces using atomic force acoustic microscopy (AFAM), which is a combination of atomic force microscopy and acoustic waves.

Characterisation of long term aging behaviour of 9Cr-1Mo ferritic steel using ultrasonic velocity
TL;DR: In this article, the authors measured the ultrasonic velocity of 9Cr-1Mo ferritic steel thermally aged at 793 and 873 K and found that four distinct regimes in the variation of ultrasonic velocities with aging time were correlated with the progressive evolution and coarsening of precipitate microstructure.
Journal ArticleDOI
Improving the evaluation sensitivity of an ultrasonic pulse echo technique using a neural network classifier
TL;DR: In this paper, the use of an artificial neural network (ANN) for classifying weak ultrasonic signals has been attempted and the limitations of using a single conventional parameter for signal detection and classification (namely peak amplitude alone) are highlighted.
Journal ArticleDOI
Synthesis of nanostructured goethite and magnetite particles from the oxidation of Fe(OH)2 in a high-oxygen-flow-rate medium
TL;DR: In this paper, the results on the oxidation of ferrous hydroxide under different oxygen flow rates are reported, showing that higher the oxygen flow rate, the higher the superparamagnetic goethite content and the smaller the crystallite size (nanometric scale) of both oxidation products.

Numerical modelling and experimental determination of temperature distribution during manual metal arc welding
TL;DR: In this paper, a three-dimensional computer model based on the control volume method has been developed to predict the temperature distribution in the heat affected zone (HAZ) and in the base plate region of the bead on plate welds, using the weld parameters as input data to the computer model.
