Soares et al. (2014) have simulated the mobilization of residual oil ganglia by the magnetic stresses generated in a ferrofluid.
Ryoo et al. (2012) use ferrofluid made of iron oxide nanorods that is sufficient to produce measurable displacement of the interface between fluid and a ferrofluid when exposed to an oscillatory magnetic field [11].
After double-annealing process at 1000°C and 1200°C for 2 hours, almost pure YIG nanoparticles formed as similar to the finding in Ristic et al. (2003) although a different chemical route was used in this work [17].

Wang et al. [13] have proved that the surface layers of black mirrors in ancient china were mainly composed of nanometer-sized particles of Sn1-x(CuFePbSi)xO2 with cassiterite structure.
Herrera et al. [17-19] have demonstrated the alteration of the tin amalgam mirrors and the formation of SnO2.
These values are in agreement with the results reported by Wang et al. [13, 33], who studied the presence of SnO2 in ancient Chinese black mirrors and also synthesized SnO2 particles.

For the fast component of the neutron spectrum, El-Sersy et al. [66] obtained an efficiency value of ε = 3.1 x 10 -5 tracks/neutron, probably employing cadmium filter as a cut-off for thermal neutrons.

In order to achieve the required microstructure and high level of both strength and toughness, Hsu proposed a novel Q–P–T heat treatment process, which is a modified Q&P process proposed by Speer et al. in 2003 [4]: austenitisation at a temperature slightly above Ac3 for obtaining fine grain austenite followed by quenching, partitioning and tempering.
Therefore, the differences between Q–P–T and Q&P processes can be summarized as two aspects: 1) carbide former elements are added in Q–P–T steels, but not permitted in Q&P steels based on constrained carbon paraequilibrium (CCE) theory proposed by Speer et al[4,5]; 2) the tempering temperature and time favourable for the precipitation strengthening determine partitioning temperature and time in Q–P–T process, namely tempering includes partitioning, but partitioning temperature and time in Q&P process can be selected in wide extension.
Fig.2 Tensile properties of medium carbon Q–P–T steels as a function of partitioning/tempering time, in which Rm represents tensile strength and El represents elongation [1] Since steels with the tensile strength of 2000 MPa are usually limited in industrial production due to the ability of sequent mechanical working (such as cutting, alignment, etc.), new generation steels with PSE higher than the upper limit value (25 000 MPa%) of AHSSs will be devoted to developed.
Zackay et al. [8] proposed the transformation induced plasticity (TRIP) effect in 1967.
