Quantitative validation of AI-derived tsunami water levels using co-located tide-gauge observations during the 2025 Kamchatka Earthquake

Earth, Planets and Space
Camera-based extraction of tsunami water-level time series has recently become feasible through deep learning segmentation, but its quantitative validity has not been established using strictly co-located tide-gauge observations during a real tsunami ...

Spacecraft angular rate estimation via event-based camera sensing

Advances in Space Research
This paper presents a method for determining spacecraft angular rates using event-based camera sensing. This is achieved by analyzing the temporal distribution of brightness events triggered by the apparent motion of stars. The location and polarity of the events are used to infer the apparent motion field of the stars, which is, in turn, employed to ...

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

A Molecular Shielding Strategy to Develop Low Protein Binding, Renal Clearable Pan‐Cancer Near‐Infrared Probes

Advanced Functional Materials, EarlyView.
A molecular shielding strategy to convert “protein‐sticky” and “non‐tumor specific” clinical ICG dye, into a “low protein binding” and “tumor‐targeting” dye with prolonged blood circulation and renal clearance is described. These shielded ICGs demonstrate strong tumor accumulation and optimal tissue clearance, resulting in high tumor‐to‐background ...

Event-based camera for meteor science

Meteor observations aim to produce the astro-photometric data to derive their orbit and light curve, from which the structure, age and origin of meteoroids can be studied. One limitation is the data acquisition rate, typically restricted to 30 fps for common video cameras.

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

Advanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Low‑Cost, High‑Dynamic, Large Field‑of‑View Detection and Tracking of Low‑Slow‑Small Aerial Vehicles

Shuju Caiji Yu Chuli
The rise of the low‑altitude economy has led to the widespread adoption of small unmanned aerial vehicles （UAVs） in logistics， surveying， and entertainment， yet the associated security risks have grown increasingly prominent.
