Advanced 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 ...

Influences of wake-effects on bubble dynamics by utilizing micro-pin-finned surfaces under microgravity [PDF]
, 2017 The influences of wake on bubble dynamics under various heat fluxes have been studied in microgravity. Nucleate pool boiling experiments of FC-72 on silicon chips fabricated with micro-pin-fins were conducted in 10(-3) gravitational acceleration for 3.6 ...

Advanced Engineering Materials, EarlyView.A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Grouping method for acoustic wave propagation in bubbly liquids
Engineering Applications of Computational Fluid MechanicsThe 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

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