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 ...

A Compact and Fast Single‐Spike TTFS Encoder With Ultralow Operating Voltage for Efficient Neuromorphic Fourier Transform

open access: yesAdvanced Science, EarlyView.
A Pt/TaOx/V single‐spike TTFS encoder achieves ultralow‐voltage (∼0.35 V), high‐speed (∼100 ns) operation with simplified circuitry. Integrating bipolar nonuniform temporal encoding with a spiking‐DFT neuron model enables a neuromorphic FFT framework. Device‐calibrated simulations demonstrate high spectral fidelity across multitone, speech, and chirp ...

CRISPR‐Scan: Cas13a Mismatch Tolerance Enabled Ultra‐Multiplexed Detection of Same‐Site Indels in Acute Myeloid Leukemia

open access: yesAdvanced Science, EarlyView.
Accurately detecting diverse same‐locus insertions or deletions (indels) remains challenging. This study reveals the mismatch‐tolerance profile of LwaCas13a and establishes CRISPR‐Scan, which uses a single crRNA to detect multiple same‐locus indels. The one‐pot assay detects nucleophosmin 1 (NPM1) mutant allele frequencies down to 0.01%, agrees with ...

Architecting Anisotropic Force‐Responsive Bidirectional High‐Contrast Three‐Color Fluorescence Switches via Effective Molecular Modulation for High‐Security Information Storage

open access: yesAdvanced Science, EarlyView.
Synergistically integrating substituent variation and positional isomerism in molecular engineering affords 13 rare tricolored mechanofluorochromic luminogens, and 3 exceedingly scarce force‐triggered bidirectional high‐contrast three‐color fluorescence switches are screened out via a three‐step protocol.

To Be or Not to Be Eutectic: Anomalous Glass Forming Ability Governed by Melt Structural Complexity

open access: yesAdvanced Science, EarlyView.
Challenging the eutectic rule, congruently melting Ti–Cu alloys show greater glass‐forming ability than their eutectic counterparts. This arises from the congruent melt's structural complexity: higher cluster diversity and stronger inter‐cluster correlations from entropy–enthalpy competition.
