Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Confinement Induced Alteration in Interfacial Energy [PDF]

Hypothesis: When a liquid is confined between two parallel plates, the pressure field at its bulk alters, because of the concave meniscus at the air-water interface. For an aqueous surfactant solution in contact with an oil, like an oil-in-water emulsion,

From cold start to sustainable operation: a strategy for disruption prediction across the tokamak lifecycle

Nuclear Fusion
Plasma disruption is a significant challenge in tokamak fusion, especially in large-size future devices like ITER, where it causes severe damage. Safeguarding future tokamaks throughout their entire lifecycle demands a disruption prediction strategy that

Confinement-Induced Stiffening of Elastomer Thin Films

, 2018
While entropy is understood to dictate the elastic mechanics of elastomers, a consensus has not been reached regarding why they stiffen when confined to thin films or even the magnitude of this effect.

Effects of neoclassical toroidal viscosity on toroidal rotation under electron cyclotron resonance heating on J-TEXT tokamak

Nuclear Fusion
Influence of neoclassical toroidal viscosity (NTV) torque on intrinsic toroidal rotation caused by internal kink mode (IKM) in the J-TEXT tokamak is studied.

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

Advanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Confinement-Induced Catalytic Dissociation of Hydrogen Molecules in a Scanning Tunneling Microscope

The catalytic scission of single chemical bonds has been induced by the nanoscale confinement in a scanning tunneling microscope (STM) junction. Individual hydrogen molecules sandwiched between the STM tip and a copper substrate can be dissociated solely
