Constitutive models dealing with the thermal and visco-plasticity of metals have seen wide applications in automotive industry. A basic plasticity fracture characterization a 1.5 mm thick DP780 dual phase steel sheet based on uniaxial tensile (UT) experiments seven distinct material orientations is complemented by low (∼0.001/s), intermediate (∼1/s) high (∼150/s) strain rate notched (NT) shear (SH) specimens at temperatures ranging from 20 °C to 500 °C. At rates, we observe non-monotonic...
A realistic first-principle-based spin Hamiltonian is constructed for the type-II multiferroic NiI_{2}, using a symmetry-adapted cluster expansion method. Besides single ion anisotropy and isotropic Heisenberg terms, this model further includes Kitaev interaction biquadratic term, can well reproduce striking features of experimental helical ground state, that are, e.g., proper screw canting rotation plane, propagation direction, period. Using to build phase diagram, it demonstrated that, (i)...

Recently, two monolayer magnetic materials, i.e., ${\mathrm{FePS}}_{3}$ and ${\mathrm{NiPS}}_{3}$, have been successfully fabricated. Despite them having the same atomic structure, monolayers exhibit distinct properties. holds an out-of-plane zigzag antiferromagnetic (AFM-ZZ) while ${\mathrm{NiPS}}_{3}$ exhibits in-plane AFM-ZZ structure. However, there is no theoretical model that can properly describe its ground state due to lack of a full understanding interactions. Here, by combining...
Type-II multiferroicity, where electric polarization is induced by specific spin patterns, crucial in fundamental physics and advanced spintronics. However, the model magnetoelectric coupling mechanisms prototypical type-II multiferroic ${\mathrm{CuFeO}}_{2}$ Al-doped remain unclear. Here, considering both alloy degrees of freedom, we develop a magnetic cluster expansion method, which considers all symmetry allowed interactions. Applying such not only obtain realistic that can correctly...
Skyrmionic magnetic states are promising in advanced spintronics. This topic is experiencing recent progress 2D magnets, with, for example, a near 300 K Curie temperature observed Fe3 GeTe2 . However, despite previous studies reporting skyrmions , such system remains elusive, since it has been reported to host either Néel-type or Bloch-type textures, while net Dzyaloshinskii-Moriya interaction (DMI) cannot occur this compound symmetry reasons. It thus desirable develop an accurate model...
Present-day liquid-state lasers are based on organic dyes. Here we demonstrate an alternative class of liquid that use solutions colloidal quantum dots (QDs). Previous efforts to realize such devices have been hampered by the fast non-radiative Auger recombination multicarrier states required for optical gain. overcome this challenge using type-(I + II) QDs, which feature a trion-like gain state with strongly suppressed recombination. When combined Littrow cavity, static (non-circulated)...
Luminescent solar concentrators (LSCs) have emerged as a disruptive technology that can potentially enable carbon-neutral buildings. The issues with current LSCs, however, are low optical efficiencies and limited long-term outdoor stability. Here we simultaneously address them by developing an LSC aggregation-induced-emission (AIE) molecules embedded in polydimethylsiloxane (PDMS) matrix. AIE-emitter displayed near unity emission quantum yield when the PDMS apparent absorption-emission...

Such successfully reproduces artificially...
Abstract Colloidal quantum‐dot (QD) lasing is normally achieved in close‐packed solid‐state films, as a high QD volume fraction required for stimulated emission to outcompete fast Auger decay of optical‐gain‐active multiexciton states. Here new type liquid optical‐gain medium demonstrated, which compact compositionally‐graded QDs (ccg‐QDs) that feature strong suppression are liquefied using small amount solvent. Transient absorption measurements ccg‐QD suspensions reveal broad‐band optical...
