Targeted Modulation of d‐Band Center in MoS2 Interlayer With n‐Type Co/Fe Dopants Accelerating Sulfur Reaction Kinetics in Lithium‐Sulfur Batteries

open access: yesAdvanced Materials, EarlyView.
A targeted modulation of the MoS2 electronic structure is achieved via substitutional n‐type Co/Fe co‐doping. This strategy triggers S‐mediated d‐p hybridization, optimizing the binding affinity with polysulfides to establish a volcano‐shaped relationship between the d‐band center and catalytic activity.

Probabilistic Forward Modeling of Galaxy Catalogs with Normalizing Flows

open access: yesThe Astronomical Journal
Evaluating the accuracy and calibration of the redshift posteriors produced by photometric redshift (photo- z ) estimators is vital for enabling precision cosmology and extragalactic astrophysics with modern wide-field photometric surveys.

Accurate spectroscopic redshift estimation using nonnegative matrix factorization: Application to MUSE spectra

open access: yesAstronomy & Astrophysics
Accurate and automated galaxy redshift determinations are essential for maximizing the scientific return of spectroscopic surveys. In this paper, we propose a data-driven method to address this challenge.

Programmable Stepwise Heteroepitaxial Growth of Colloidal Crystals With Different Phases

open access: yesAdvanced Materials, EarlyView.
Stepwise heteroepitaxial growth is adapted to colloidal crystal engineering with DNA, enabling face‐centered cubic (fcc) facets to grow on body‐centered cubic (bcc) crystals with 110 facets. This approach tolerates large lattice mismatches, extending heteroepitaxy beyond the limits of conventional atomic systems.

JWST Discovery of a High-redshift Tidal Disruption Event Candidate in COSMOS-Web

open access: yesThe Astrophysical Journal
The rates and properties of tidal disruption events (TDEs) provide valuable insights into their host galaxy central stellar densities and the demographics of their central supermassive black holes. TDEs have been observed only at low redshifts ( z  ≲ 1),

The Stromlo-APM Redshift Survey. IV. The Redshift Catalog

open access: yesThe Astrophysical Journal Supplement Series, 1996
The Stromlo-APM Redshift Survey consists of 1797 galaxies with {ital b}{sub {ital J}}{le}17.15 selected randomly, at a rate of 1 in 20 from automated plate measurement (APM) scans. The survey covers a solid angle of 1.3 sr (4300 deg{sup 2}) in the south Galactic cap. Redshifts have been measured for 1790 (99.6{percent}) of the galaxies.

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

open access: yesAdvanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

Interaction between Galaxies and the Intergalactic Medium at z = 3 [PDF]

open access: yes, 2009
In this thesis, we aim to study the clustering properties of galaxies at z ≈ 3 and the relationship between galaxies and the IGM at these redshift via clustering correlation functions.
