The pressure dependence of the molar volume was at constant temperatures close to the melting point in benzene. The molar volume of benzene was calculated using experimental data for the thermal expansivity for constant temperatures of 25°C, 28.5°C, 40°C, and 51°C at various pressures for both the solid and liquid phases. The predictions are in good agreement with the observed ...

Summary form only given. We show that in an electron-light ion-heavy ion plasma, the light component can rotate with a frequency, Omega<sub>r</sub> = (Zn<sub>H</sub>/n<sub>e</sub>)Omega<sub>L</sub> where n<sub>H</sub> and n<sub>e</sub> are their densities, Z is the heavy ion charge state, and Omega<sub>L</sub> is the light ion gyro-frequency. There is a current perpendicular to the magnetic field due to the light ion and electron EtimesB drift, which induces an electric field in the direction of the current. Hence the plasma is subject to electric forces simultaneously in the two orthogonal directions perpendicular to the magnetic field resulting in rotation of the lighter fluids. Omega<sub>r</sub> falls in-between the light and heavy ion cyclotron frequencies. The rotation introduces a new time scale and can significantly affect the waves with frequencies close to Omega<sub>r</sub>. This is analogous to the cyclotron phenomenon but distinct from it. We show that for the rotation waves, the wave energy is mainly in the kinetic (rotation) energy of the light ion fluid which affects the large-scale MHD properties; in particular, the character of turbulence. For example, the nonlinear MHD wave evolution near Omega <sub>r</sub> is governed by a nonlinear Schrodinger equation. For long wavelengths (kVA = Omega<sub>r</sub>) the dispersion relation becomes isomorphic to the electrostatic Langmuir wave dispersion relation. The interaction of the fast rotation time-scale with the slow heavy ion magnetosonic time-scale is achieved via ponderomotive force resulting in the formation of long wavelength condensates and strong turbulence. This implies that the turbulence spectrum is likely to be determined by the appearance and collapse of solitons into structures with scale size L~VA/Omega<sub>r</sub>. We also show that nonlinearly the waves near Omega<sub>r</sub> can support large magnetic gradients and lead to plasma energization. Applications to space and astrophysical environments will be discussed
The pressure dependence of the molar volume was at constant temperatures close to the melting point in benzene. The molar volume of benzene was calculated using experimental data for the thermal expansivity for constant temperatures of 25°C, 28.5°C, 40°C, and 51°C at various pressures for both the solid and liquid phases. The predictions are in good agreement with the observed volumes in both the solid and liquid phases of benzene. The predicted values of the molar volume for a constant temperature of 28.5°C in the liquid phase of benzene agree well with experimental data in the literature.
It is known that when the probe vibrating in liquid, the oscillation of the cantilever is significantly damped by the interaction forces between the water molecule and the probe surface, which is known as the hydration force. Thus, the parameters of a tapping magnetic probe are affected. In this work, the resonant frequency, Q-factor and spring constant of the magnetic probe in air and liquid environments were analyzed. The MFM images of a hard disk acquired in ambient and liquid conditions were compared. It was found that the hydration force affected the parameters of the magnetic probe and then the quality of the MFM images was decreased. To improve the quality of the magnetic images, the drive amplitude and the lift height were adjusted. The results showed that the magnetic features were recognized with the increases of the drive amplitude and the appropriate lift height.
We are developing a shear-type compact MR brake (SCMRB), which can control the share stress because the viscosity of MR fluid varies by the magnetic field and shear rate. In order to design the high response brake, it is important to evaluate the response characteristics by taking into account the non-linearity of stress versus flux density and stress versus rotation speed. This paper presents the response characteristics analysis method of the SCMRB using the 3-D finite element method (FEM). The effectiveness of the analysis is clarified through the comparison with the measured ones. Furthermore, the usefulness of this brake is also clarified through the response characteristics.
This study presents a novel sensor to detect the angular motion (both in-plane and out-of-plane) of an object using the capacitance change induced by magnetic field. The magnet-sensitive NdFeB powder is well mixed with liquid Glycerol, and then dispensed into a cavity on silicon chip. The parylene C film is deposited to seal the cavity with NdFeB/Glycerol mixture . Nevertheless, the NdFeB powder remains free to move inside the Glycerol. As the chip approach a rotating magnetic field, each NdFeB powder will spin in such field and lead to the capacitance change of the sensor. This study has implemented the presented sensor, and typical measurement show that a 100 to 300rpm/140Gauss magnetic field has been successfully detected by the sensor with capacitance varying from 0.023pF to 0.016pF.
Magnetic fluid is a new type of optical functional material. When it is made as a film, a hexagonal order structure can be formed under an external magnetic field. This novel magnetic-field dependent structure may be regarded as a kind of magnetic fluid photonic crystal. The slow light property in the magnetic fluid photonic crystal was studied in this letter. It was pointed that the geometry parameters of the structure could be tuned by changing the applied temperature. In addition, photonic bandgap and group velocity as a function of temperature were simulated. The results showed that the upper and lower normalized frequency of the photonic bandgap would both shift to higher frequencies, and the maximal group velocity <;0.25 c was obtained, which could be thermally tuned in a large range. The working frequency corresponding to the maximal group velocity would change from 0.2063 to 0.4312 (a/λ) when the external temperature was increased from 18 °C to 48 °C. These results fully proved that the magnetic fluid photonic crystal, as a type of thermally modulated photonic crystal, could be used in the field of optical sensors. It also provided a new idea for generating slow light in colloid photonic crystal waveguide.
