Self‐Catalyzed Chemically Coalescing Liquid Metal Emulsions
Advanced Science, EarlyView.A new type of liquid metal emulsion is developed that chemically activates and becomes electrically conductive under mild thermal stimulus. The activation mechanism occurs through a unique set of catalytic dehalogenation and chemical oxide etching reactions. These emulsions are 3D printable and exhibit high shape retention after being heated.

Modeling of Crescent‐Type Internal Gear Pumps Considering Gear Radial Micromotion
Chemical Engineering &Technology, Volume 46, Issue 1, Page 128-136, January 2023., 2023 A numerical approach for investigating crescent‐type internal gear pumps, coupling a lumped parameter pressure solver with a CFD film simulator based on transient gap geometries solved from gear loading forces was proposed. Volumetric efficiency prediction was validated by measurements.

Kinematic Description of Ricci Solitons in Fluid Spacetimes [PDF]
arXiv, 2017 We consider the kinematics of specific fluid spacetimes admitting timelike congruences of Ricci Solitons. These fluids includes string cloud, string fluid, perfect fluid, radially symmetric fluid, anisotropic fluid and relativistic magneto-fluid. Results are obtained and important physical aspects are discussed.

Advanced Science, EarlyView.In summary, a universal EGaIn‐based DIW printing strategy is presented for fabricating wideband stretchable antennas. The printed antenna achieves an operating bandwidth of 3.75–8.21 GHz (fractional bandwidth: 75%), a peak gain of 1.8 dB and a radiation efficiency of 76.6%, surpassing state‐of‐the‐art stretchable antennas. More importantly, the antenna

Chemical Engineering &Technology, Volume 46, Issue 1, Page 95-101, January 2023., 2023 The bulk shear and wall slip of a confined nonpolar lubricant, a complex branched‐hydrocarbon oil, were studied using molecular dynamics simulation. Different temperatures and molecular masses were investigated for a Couette flow. As the number of branches of the liquid molecule increases, the shear stresses and the wall slip increase.

Elastohydrodynamic Simulation of Pneumatic Sealing Friction Considering 3D Surface Topography
Chemical Engineering &Technology, Volume 46, Issue 1, Page 167-174, January 2023., 2023 The influence of the surface topography of the sealing counterface in a pneumatic spool valve on the sealing friction force during operation is investigated. For that, the 3D surface topography of the running surface has been measured optically. Using an elastohydrodynamic lubrication simulation, it could be demonstrated that the surface topography ...

Symmetric hyperbolic Euler equations for relativistic perfect fluids [PDF]
arXiv, 2005 The Euler equations governing a relativistic perfect fluid are put into symmetric hyperbolic form with dependent variables the fluid's specific entropy plus a generalized velocity vector equal to the fluid's unit relativistic velocity vector divided pointwise by the fluid's specific enthalpy.
