Effect of phonon-boundary scattering on phonon-drag factor in Seebeck coefficient of Si wire

AIP Advances, 2020
For highly efficient thermoelectric devices with Si nanostructures, we have fabricated and characterized micro/nanometer-scaled Si wires preserving the phonon-drag effect in order to observe the impact of phonon-boundary scattering on the phonon-drag ...

Drag coefficients in hydraulic channel

, 2022
Experimental information is extremely useful in solving problems involving flow over bodies, as well as for determination of design parameters in aerodynamics and hydrodynamics, the drag coefficient being one of the most relevant as it allows to quantify the drag forces, that is, the total resistance of a body being dragged by a fluid. In this context,

Determination Of The Surface Drag Coefficient

Boundary-Layer Meteorology, 2001
This study examines the dependence of the surface drag coefficienton stability, wind speed, mesoscale modulation of the turbulent flux and method of calculation of the drag coefficient. Data sets over grassland, sparse grass, heather and two forest sites are analyzed.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Drag Force on Submerged Flexible Vegetation in an Open‐Channel Flow

Water Resources Research
The movement of submerged flexible vegetation leads to an increase in resistance to the stream flow. In this study, a formula that can directly calculate the drag force on a highly flexible submerged vegetation, called Ceratophyllum, by using the ...

Machine‐Learning Microfluidic Minute‐Scale Microorganism Metrics Monitoring(M6)

Advanced Science, EarlyView.
ABSTRACT On‐site monitoring of microorganisms remains challenging because of low concentrations, strong background interference, and dynamic aerosol diffusion, particularly for aerosol‐transmitted pathogens. Here, we report a rapid detection platform that integrates a Puri‐focusing microfluidic chip, electrochemical impedance spectroscopy (EIS), and ...
