Batteries of electric vehicles require appropriate cooling to allow for increased performances such as high energy density and fast charging capabilities. Immersion the cells in a dielectric fluid provides substantial benefits terms safety performance, but selection relevant coolant remains complex task guidance engineers field vehicle electrification is sparce. This paper reviews properties wh...

Abstract Background Remote dielectric sensing (ReDSTM) is a recently introduced non-invasive electromagnetic-based technology to quantify lung fluid levels (Figure 1A). The association between ReDS values and invasively measured hemodynamics, particularly among those with small body size, remains uncertain. Methods Consecutive patients chronic heart failure who were admitted our institute under...

Triboelectric nanogenerators are aspiring energy harvesting methods that generate electricity from the triboelectric effect and electrostatic induction. This study demonstrates the harvesting of wind energy by a wind-rolling triboelectric nanogenerator (WR-TENG). The WR-TENG generates electricity from wind as a lightweight dielectric sphere rotates along the vortex whistle substrate. Increasing...

Leaky Lamb waves are important research topics in the area of NDE and acoustic wave sensing technology. For waves propagating in a piezoelectric plate immersed in a fluid (dielectric or conductive), both mechanical and electrical loading effects present and result in phase velocity variation and wave attenuation. To quantitatively characterize these loading effects play an important role in var...

Monodisperse anisotropic particles have tremendous potentials in materials science and engineering (Hosein et al., 2010). As one of this kind of materials, snowman-like particles have drawn a special attention in the aspects of both their synthesis mechanism and applications. In this study, we synthesized micron-sized snowman-like poly(methyl methacrylate) (PMMA) particles via a seed emulsion p...

The dielectric barrier discharge (DBD) plasma actuator offers promising opportunities for flow control because it does not require mass injection and involves no moving mechanical components. In order to gain better understanding of the impact of the materials and operational parameters on the performance of the DBD actuator, and to facilitate design of effective control schemes, the surrogate ...
