A first principles investigation on the mechanism of TiC act as heterogeneous nucleation substrate of Mg phase to refine grains in AZ91

AIP Advances, 2019
The lattice misfit of small Miller indices crystal faces between Mg and TiC is calculated based on Bramfitt two-dimensional lattice misfit theory.

Dependence of boundary lubrication on the misfit angle between the sliding surfaces

, 2010
Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the ...

Spin‐Selective Interface Engineering in Oxide–Ferromagnetic Junctions via Atomic‐Scale Oxygen Control

Advanced Science, EarlyView.
We show that interfacial oxygen at the MgO/Fe interface can be transformed from an uncontrolled variable into a tunable design parameter for spintronic junctions. Momentum microscopy provides direct access to the momentum‐ and spin‐resolved electronic structure beneath the insulating MgO layers, revealing how oxygen intercalation reshapes buried Fe ...

Misfit-dependent interaction mechanisms between γ-phase dislocations and interfacial dislocation networks in nickel-based single crystal superalloys under [001] tensile loading

Materials & Design
Understanding the dislocation–interface interaction mechanisms at atomic-scale is crucial for improving the temperature capacity of Ni-based single-crystal superalloys.

A Si‐MoSe2 Heterostructured Anode with Enhanced Thermal Transport and Electrochemical Performance for Liquid and All‐Solid‐State Lithium‐Ion Batteries

Advanced Science, EarlyView.
Chemically bonded Si@MoSe2@C heterointerfaces with robust Si─Se─Mo bonds enable high‐performance Si anodes. Lattice‐matched MoSe2 on porous Si with carbon‐protective coating delivers 1054 mAh g−1 after 100 cycles and 99.5% Coulombic efficiency over 400 cycles.

Temperature-Dependent Accommodation of Two Lattices of Largely Different Size during Growth

Nanomaterials, 2019
If a material grows on another material with a largely different lattice constant, which of the two adapts for an energetically favorable growth? To tackle this question, we investigate the growth of Ag on Cu(111) by variable temperature scanning ...

Real-time monitoring of stress evolution during thin film growth by in situ substrate curvature measurement

, 2019
Strain engineering is the art of inducing controlled lattice distortions in a material to modify specific physicochemical properties. Strain engineering is applied for basic fundamental studies of physics and chemistry of solids but also for device ...

Hydrogen‐Induced Amorphization of Superlattice Cerium Nickel Intermetallics Enabling Efficient Alkaline Oxygen Evolution Reaction

Advanced Science, EarlyView.
A gaseous hydrogen engineering strategy is employed to induce the amorphization of superlattice‐structured CeNi3 intermetallic, facilitating alkaline OER‐driven phase reconstruction and enhancing catalytic performance. ABSTRACT Transforming intermetallics with highly ordered structures into amorphous forms to unlock their superior oxygen evolution ...

Revealing intrinsic strain and domain evolution across the pristine phase transition using PbTiO3 epitaxial films with negligible residual strain [PDF]

APL Materials
Displacive ferroelectrics exhibit a strong coupling between lattice anisotropy and intrinsic structural distortions, and epitaxial constraints in thin films make it essential to directly monitor strain-driven structural responses under controlled ...
