Engineering Borophene Band Structure Through Thickness

open access: yesAdvanced Science, EarlyView.
Borophene grown on W(110) shows a thickness‐dependent evolution of its structural and electronic properties. Surface microscopy, diffraction, XPS, and ARPES reveal distinct monolayer and bilayer phases. The formation of the second layer is accompanied by structural reconstruction, changes in chemical properties, and new ARPES features, demonstrating ...

Synergistic Frequency-Spatial Enhancement With Temporal Correlation for Robust Satellite Video Tracking

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The adjacency effect introduces a coupled challenge of blurry targets and similar-object interference in satellite videos, leading to severe ambiguity in template matching and error accumulation in existing satellite video single object tracking (SOT ...

Spontaneous Cyclic Levitation of Glycerol‐Water Droplets at Low Pressures

open access: yesAdvanced Science, EarlyView.
Under low pressure, a minute glycerol addition transforms the chaotic dynamics of freezing water droplets into cyclic levitation. Freeze‐concentration preserves liquid pathways that relax expansion‐induced stress, while freezing point depression weakens asymmetric vaporization recoil.

Detaching Photosensitive Nanoparticles from Cells Prevents Them from Remaining in Cells after Photoporation

open access: yesAdvanced Science, EarlyView.
Phenylboronic acid‐functionalized gold nanoparticles reversibly attach to cell‐surface glycans, enhancing photoporation‐mediated intracellular delivery. After irradiation, ATP competitively disrupts the boronic ester interactions and removes cell‐associated nanoparticles, markedly reducing residual gold.

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides

open access: yesAdvanced Science, EarlyView.
Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...

Uniaxial Strain‐Driven Ferroelastic Domain Tuning in LaAlO3${\rm LaAlO}_3$

open access: yesAdvanced Science, EarlyView.
The present work demonstrates based on AFM, μ$\umu$‐Raman spectroscopy, XRD, and first‐principles, that uniaxial strain provides a handle for tuning the ferroelastic domain populations in lanthanum aluminate, driving a continuous and controlled phase transition from a four‐variant rhombohedral crystal system to a two‐variant orthorhombic crystal system
