Unconventional Topological Weyl Dipole Phonon

open access: yesAdvanced Science, EarlyView.
A new higher‐order topological phonon state is proposed, which integrates an unconventional Weyl dipole phonon (a charge‐3 Weyl point and three charge‐1 Weyl points) with higher‐order topology. Moreover, the two Weyl dipoles in Y(OH)3 exhibit the sextuple‐helicoid surface and hinge boundary states from the nonzero topological charge (±6) and the ...

Determination of the Kinetic Rates and Intrinsic Nonradiative Losses in Organic Thermally Activated Delayed Fluorescence Emitters

open access: yesAdvanced Science, EarlyView.
It is demonstrated that the kinetic rates and intrinsic nonradiative losses of purely organic emitters with thermally activated delayed fluorescence cannot be precisely determined by photoluminescent measurements alone. With device modeling, it is then possible to quantify the absolute nonradiative losses from singlets and triplets, and therefore the ...

Low‐Temperature Annealing Triggered Abnormal Strengthening in a Complex Concentration Alloy via Evolutive Short‐Range Ordering

open access: yesAdvanced Science, EarlyView.
Low‐temperature annealing enhances strength, ductility, and work hardening in CoNiV MEA. This originates from multi‐scale chemical short‐range orderings (SROs) formed during annealing, which promote dislocation slip planarity and reduce entanglement, enabling balanced mechanical properties through ordering strengthening.
