One‐Step Fabrication of Highly Transparent Superhydrophobic Coatings Via Atmospheric Pressure Radio Frequency Plasma Deposition

Advanced Materials Interfaces, EarlyView.
Atmospheric‐pressure RF plasma deposition enables the fabrication of transparent, superhydrophobic coatings with anti‐reflective functionality. Process optimization yields high optical transmittance, robust environmental stability, and self‐cleaning properties.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Simulations of the Onset and Dynamical Evolution of Inertial Waves in Solar/Stellar Interior

The Astrophysical Journal
Inertial modes have been recently detected in the Sun via helioseismology, yet their origin, evolution, and role in the dynamics of the solar plasma and magnetic field remain poorly understood.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Using Polar Faculae to Determine the Sun’s High-latitude Rotation Rate. II. Simulations and New Measurements

The Astrophysical Journal
In a previous paper, I described a new way of determining the high-latitude solar rotation rate statistically from spacetime maps of polar faculae observed in the 6767 Å continuum by the Michelson Doppler Interferometer on the Solar and Heliospheric ...

The 11-year solar cycle, the 27-day Sun's rotation and the area of the stratospheric Aleutian high

Meteorologische Zeitschrift, 2001
The effect of the 11-year solar cycle on the 30-hPa geopotential height and temperature fields in the area of the Aleutian high caused by solar activity oscillations resulting from the Sun's rotation (27.2 d) is investigated, applying methods of ...

Stellar Rotation in an Old Solar Twin Using ESPRESSO/VLT Validates Gyrochronology

The Astrophysical Journal Letters
We report the detection of rotation in the old (∼7 Gyr) solar twin HIP 73815. This result provides new insight into the validity of gyrochronology beyond the solar age, a subject of intense debate in recent years.

Three‐Dimensional Printed Microarchitected Hierarchically Porous Biodegradable PLA/S/CNT Nanocomposite Electrodes for High‐Performance Lithium–Sulfur Batteries

Advanced Materials Technologies, EarlyView.
Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...
