Quasi‐Antipolar Nanoclusters Driven Superior Energy Storage in High‐Entropy Relaxor Ferroelectrics

open access: yesAdvanced Science, EarlyView.
Quasi‐antipolar nanoclusters are engineered in lead‐free NaNbO3‐based high‐entropy relaxors that weaken polar nanoregion coupling and induce distinct ferroelectric transition under high fields to enable desirable polarization response. This breakthrough system achieves ultrahigh recoverable‐energy‐density (≈18.3 J cm−3), efficiency (≈91.5%), and ...

[The brief history of Korean traditional medicine (1899-1999)].

open access: yesUi sahak, 2002
Since Korea had opened her ports to foreign forces, the typically royal system of her traditional medicine started to turn its attention more to a modernized and folk-focused one. After the Kap-oh Reformation (1884) had ended in vain, under the spirit of the 'Eastern mind in Western frame' that gained influence during Kwang-moo Reformation (1896-1905),

Laser‐Architected Shape‐Configurable Vertical Graphene Thermoacoustic Loudspeakers for 3D Acoustic Emission

open access: yesAdvanced Science, EarlyView.
A dual‐laser‐architected vertical graphene film enables high‐performance, morphologically reconfigurable thermoacoustic loudspeakers.The vertically aligned graphene structures combine efficient heat dissipation, thickness‐independent SPL, and kirigami‐driven 3D transformations, offering shape‐programmable, stretchable, and omnidirectional acoustic ...

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

open access: yesAdvanced Science, EarlyView.
In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...
