The acquisition of acoustic radiation characteristics of underwater cylindrical free-field

open access: yesZhongguo Jianchuan Yanjiu
[Objectives] Measurement of acoustic characteristics of underwater targets is usually affected by the sea surface, seabed and external noise sources. It is difficult to obtain the free-field acoustic radiation characteristics of the targets.

Freestanding PZT Films for Integrated Wearable Sensing and Intelligent Acoustic Recognition

open access: yesAdvanced Science, EarlyView.
A freestanding epitaxial PZT/LaNiO3/Pt heterostructure is achieved via water‐assisted delamination from mica, effectively eliminating substrate‐induced clamping and releasing intrinsic ferroelectricity. The released film exhibits substantially enhanced remanent polarization and piezoelectric response, delivering excellent mechanical flexibility and ...

Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

open access: yesAdvanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Optical Access to Dark Excitons Via Spin–Phonon Fano Interference

open access: yesAdvanced Science, EarlyView.
Dark excitons in quantum dots neither absorb nor emit light and stay hidden from optical spectroscopy. Quantum interference now reveals them: light scattered by acoustic phonons interferes with a phonon‐assisted spin flip between bright and dark exciton, carving a Fano dip into the spectrum whose position gives the bright–dark splitting. Magnetic field,
