Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

open access: yesAdvanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

Simulation of coalescence, break up and mass transfer in bubble columns by using the Conditional Quadrature Method of Moments in OpenFOAM [PDF]

open access: yes, 2013
The evaluation of the mass transfer rates and the fluid-dynamics aspects of bubble columns are strongly affected by the intrinsic poly-dispersity of the gas phase, namely the different dispersed bubbles are usually distributed over a certain range of ...

Homogeneous Bubble Nucleation driven by local hot spots: a Molecular Dynamics Study

open access: yes, 2009
We report a Molecular Dynamics study of homogenous bubble nucleation in a Lennard-Jones fluid. The rate of bubble nucleation is estimated using forward-flux sampling (FFS).

Diffusive shielding stabilizes bulk nanobubble clusters [PDF]

open access: yes, 2011
Using molecular dynamics, we study the nucleation and stability of bulk nanobubble clusters. We study the formation, growth, and final size of bulk nanobubbles. We find that, as long as the bubble-bubble interspacing is small enough, bulk nanobubbles are

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Grouping method for acoustic wave propagation in bubbly liquids

open access: yesEngineering Applications of Computational Fluid Mechanics
The bubble radii within a bubble cluster typically distribute over a wide range, and bubble dynamics under acoustic excitation are strongly dependent on the radius. To accurately predict the oscillation behaviour of the bubble cluster and the propagation

On the dynamics and breakup of a bubble immersed in a turbulent flow [PDF]

open access: yes, 2011
Experimental investigations of the dynamics of a deformable bubble rising in a uniform turbulent flow are reported. The turbulence is characterized by fast PIV.

Bubble dynamics near the onset of single-bubble sonoluminescence [PDF]

open access: yesPhysical Review E, 2004
A number of groups have reported measurements of the location in the parameter space of bubble size versus acoustic pressure amplitude of shape- and size-stable bubbles. For air/water systems, a general trend emerges: stable bubbles are found on one of two line paths in this space defined by their range of acoustic pressure.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
