Resolving the Tachocline Using Inversion of Rotational Splitting Derived from Fitting Very Long and Long Time Series

The Astrophysical Journal
We use rotation splittings derived from very long and long time series, namely 25.2, 12.6, and 6.3 yr long, computed by S. G. Korzennik independent methodology to characterize the solar tachocline and its variation with latitude and time.

Temporal Variations of the Rotation Rate in the Solar Interior [PDF]

, 2000
The temporal variations of the rotation rate in the solar interior are studied using frequency splittings from Global Oscillations Network Group (GONG) data obtained during the period 1995-1999.

Novel Functional Materials via 3D Printing by Vat Photopolymerization

Advanced Functional Materials, EarlyView.
This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Characterizing the Observational Properties of the Sun’s High-latitude m = 1 Inertial Mode

The Astrophysical Journal
Low- m inertial modes have been recently discovered in the Sun’s high-latitude regions. In this study, we characterize the observational properties of the m = 1 mode by analyzing time–distance subsurface flow maps.

Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals

Advanced Functional Materials, EarlyView.
Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...

Genetic Algorithm for Inferring Model Parameters for Flux Transport Dynamo Simulation

The Astrophysical Journal
The Sun exhibits an 11 yr cyclic variation, maintained by dynamo action in the solar interior. Mean-field flux transport dynamo models have successfully reproduced most of the features observed in solar cycles, while the model includes many free ...

Angular Momentum Transport by Gravity Waves and Its Effect on the Rotation of the Solar Interior [PDF]

, 1996
We calculate the excitation of low-frequency gravity waves by turbulent convection in the Sun and the effect of the angular momentum carried by these waves on the rotation profile of the Sun's radiative interior.

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

Advanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

Advanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Computational Seismic Holography of Acoustic Waves in the Solar Interior

, 2011
1.1 Helioseismology The advent of solar seismology is widely recognized as the independent discoveries by Leighton, Noyes & Simon (1963) and Evans, Michard & Servajean (1962) of Doppler oscillations in the Sun’s surface, mostly with periods ranging from ...
