This study elucidates the mechanism of compressible flow exfoliation for producing 2D hexagonal boron nitride (h‐BN). Fluid dynamics analysis reveals that acceleration‐driven aerodynamic shear forces, rather than shock waves alone, drive effective layer separation.

Stability of multi-electron bubbles in liquid helium
The stability of multi-electron bubbles in liquid helium is investigated theoretically. We find that multi-electron bubbles are unstable against fission whenever the pressure is positive.

State-dependent diffusion coefficients and free energies for nucleation processes from Bayesian trajectory analysis. [PDF]
The rate of nucleation processes such as the freezing of a supercooled liquid or the condensation of supersaturated vapour is mainly determined by the height of the nucleation barrier and the diffusion coefficient for the motion across it. Here, we use a

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.

Numerical investigations on bubble-induced jetting and shock wave focusing: application on a needle-free injection [PDF]
The formation of a liquid jet into air induced by the growth of a laser-generated bubble inside a needle-free device is numerically investigated by employing the compressible Navier–Stokes equations.

Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

The Centaurus A Northern Middle Lobe as a Buoyant Bubble [PDF]
We model the northern middle radio lobe of Centaurus A (NGC 5128) as a buoyant bubble of plasma deposited by an intermittently active jet. The extent of the rise of the bubble and its morphology imply that the ratio of its density to that of the ...

Phase‐changing liquids enable untethered pneumatic actuation in soft robotics but suffer from volatility and storage challenges. This work reports a simple method to encapsulate Novec 7000 within micron‐thin alginate shells via in situ injection and ionic crosslinking.

The dynamics of a gas bubble in liquid near a rigid surface
The axisymmetric dynamics of a gas bubble in liquid near a plane rigid surface (wall) during its expansion and subsequent compression with the transition to the toroidal phase of motion has been studied.

Effect of the liquid temperature on strong compression of a cavitation bubble
The influence of the liquid temperature in the range of 273.15–419 K on the vapor compression inside a collapsing cavitation bubble in acetone has been studied. The liquid pressure is 50 bar.
