Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

Cytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

P5.21 EARLY IABP INFLATION SUPPRESSES LEFT VENTRICULAR FUNCTION AS INDICATED BY WAVE INTENSITY ANALYSIS

Artery Research, 2013
Background: Timing errors during Intra-Aortic Balloon Pump (IABP) support can be detrimental when interfering with cardiac function. In vivo hemodynamics and left ventricular (LV) function were monitored during premature IAB inflation, and the associated

On-axis energy backflow in the focal fields of vector vortex beams with arbitrary initial phase

Optics Express
Energy backflow is an intriguing counterintuitive phenomenon, which has been reported in the focal region of light beams with phase or polarization singularities. Although the scenarios involving vector vortex beams with both polarization and phase singularities have been discussed, the impact of the light beam’s initial phase on ...

Study of energy backflow in unidirectional monochromatic and space-time waves

Backflow, or retropropagation, is a counterintuitive phenomenon whereby for a forward-propagating wave the energy locally propagates backward. In the context of backflow, physically most interesting are the so-called unidirectional waves, which contain only forward propagating plane wave constituents.

3D Knitted Interfacial Solar Steam Generator for High‐Efficiency and Long‐Term Seawater Desalination

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrophobic bottom provides buoyancy to keep the evaporator floating, and directional vertical spacer yarn supplies sufficient water. The knitted photothermal layer efficiently converts solar energy via multiple light reflections. The Marangoni effect induced by edge yarn accelerates the backflow of salt ions, preventing salt accumulation in the ...
