In Situ Formation of a Melt‐Solid Interface Toward Stable Oxygen Reduction in Protonic Ceramic Fuel Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Protonic ceramic fuel cells offer a promising route to generate power efficiently but face critical challenges in achieving industrially viable activity and stability at their cathodes in CO2‐containing air. This report proposes a new cathode material design strategy to enable the cathode to be both catalytically active and CO2 tolerant through the ...

Fluorine Abundances in Local Stellar Populations

The Astronomical Journal
We present the first fluorine measurements in 12 normal K giants belonging to the Galactic thin and thick disks using spectra obtained with the Phoenix infrared spectrometer on the 2.1 m telescope at Kitt Peak. Abundances are determined from the (1−0) R9

The stellar populations of the Milky Way in CFHTLS fields

EPJ Web of Conferences, 2012
We investigate the characteristics of the thick disk in the Canada – France – Hawaii – Telescope Legacy Survey (CFHTLS) fields, complemented at bright magnitudes with Sloan Digital Sky Survey (SDSS) data.

A Comparison of the Chemical Evolutionary Histories of the Galactic Thin Disk and Thick Disk Stellar Populations

, 2005
We have studied 23 long-lived G dwarfs that belong to the thin disk and thick disk stellar populations. Abundances have been derived for 24 elements: O, Na, Mg, Al, Si, Ca, Ti, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd, and Eu. We find

3D Printed Ultra‐Fast Plastic Scintillators Based on Perovskite‐Photocurable Polymer Composite

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The demand for radiation detection is increasing in a number of fields, including high‐energy physics, medical imaging, and homeland security. This study serves to demonstrate the potential for the fabrication of fast perovskite‐based scintillators with complex shapes via stereolithographic additive manufacturing, representing a new path toward the ...

Mapping the Chemodynamics of the Galactic Disk Using the LAMOST and APOGEE Red Clump Stars

The Astrophysical Journal Supplement Series
A detailed measurement is made of the metallicity distributions, kinematics, and dynamics of the thin and thick disks across a large disk volume (5.0 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc) by using the LAMOST–APOGEE red clump stars.

Kinematic and chemical components in the solar neighbourhood

EPJ Web of Conferences, 2012
Abundance data on solar neighbourhood stars suggest the presence of chemically-distinct stellar components in the solar neighbourhood. When the abundances of Fe, α elements, and the r-process element Eu are considered together, stars separate neatly into

Stochastic processes, galactic star formation, and chemical evolution. Effects of accretion, stripping, and collisions in multiphase multi-zone models [PDF]

, 2005
This paper reports simulations allowing for stochastic accretion and mass loss within closed and open systems modeled using a previously developed multi-population, multi-zone (halo, thick disk, thin disk) treatment.

GALAH survey: chemically tagging the thick disk [PDF]

EAS Publications Series, 2014
The GALAH survey targets one million stars in the southern hemisphere down to a limiting magnitude of V = 14 at the Anglo- Australian Telescope. The project aims to measure up to 30 elemental abundances and radial velocities (~1 km/s accuracy) for each star at a resolution of R = 28000. These elements fall into 8 independent groups (e.g. alpha, Fe peak,

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may
