Ngouangna et al [10] indicates that particles with larger positive or negative zeta potential values will repel each other in the base fluid and therefore will play a tendency of not agglomerating easily in the suspension for long time.

Bernardini et al. [1] investigated Fe GB diffusion in Cu at 716 K after annealing during 96 hours.
Ribbe et al. [2,3] studied Fe GB diffusion in a wide temperature range.
From their results it was seen that the annealing at 719 K during 20 hours corresponded to C regime contrary to Bernardini et al.

By measuring all kind of yield strength of metal material under ultrasonic vibration, N.Atansiu made a conclusion that material yield strength with superposition of ultrasonic is exponential function of ultrasonic intensity; Based on the principle of the strain superposition, Qing he, Bangchun Wen analyzed the reason that average stress of metal reduces in vibration plastic forming and presented a mathematical description[3]; Gaipin Cai et al. based on the basic assumption of strain history on Kirchner, they built a one-dimensional viscoelastic-plastic model for stretching vibration, which have derived the expression of viscoelastic-plastic constitutive equation[5]; Jinyin Zheng et al. on the basis of the ultra-high-frequency vibration tensile test, explored the change of constitutive behavior of materials in metal plastic deformation after the superposition of ultrasonic vibration, and gave constitutive description of materials on non-local theory[9].

For instance, Svensson et al. [9] presented a surface-micromachined pressure sensor based on a FET device, in which the diaphragm acted as the transistor gate.
Other researchers Ching-Liang Dai et al. [10] opted to utilize the commercial 0.35 nm complementary metal oxide semiconductor (CMOS) process and a post-process to fabricate the micro FET pressure sensor, where the sensor is composed of 16 sensing cells in parallel and each sensing cell includes a suspended membrane and an NMOS.
Ajay et al. [7] developed a novel MOSFET-based sensor, which exploits both the channel piezoresistance and capacitance variation effects on MOSFET.
