NLTE Analysis of Y i and Y ii in the Atmospheres of FGK Stars

The Astrophysical Journal, 2023
The nonlocal thermodynamical equilibrium (NLTE) line formation of Y i and Y ii is considered in 1D LTE model atmospheres of FGK-type stars. The model atom was constructed with the most up-to-date atomic data, including quantum cross sections and rate ...

Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom

Advanced Functional Materials, EarlyView.
The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

Differentiating the Synergistic Interactions Between Li+ Salts and Cyclic to Linear Carbonate Ratios to Enable Wide‐Temperature Performance of Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
The coordination in carbonate solvents and degradation products of lithium difluoro(oxolato) borate (LiDFOB) salt enables sufficient passivation of both LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode and graphite anode in the absence of ethylene carbonate (EC).

Bioprinted Micro‐Clots for Kinetic Analysis of Endothelial Cell‐Mediated Fibrinolysis

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper describes the development of a microscale model that quantifies the breakdown of fibrin by endothelial cells. The small size scale of this engineered system enables fibrin breakdown to be observed without the addition of external activators. This system could help in identifying compounds which both promote and hinder thrombosis.

unTimely: a Full-sky, Time-domain unWISE Catalog

The Astronomical Journal, 2023
We present the unTimely Catalog, a deep time-domain catalog of detections based on Wide-field Infrared Survey Explorer (WISE) and NEOWISE observations spanning the 2010 through 2020 time period. Detections are extracted from “time-resolved unWISE coadds,”

A Search for L/T Transition Dwarfs With Pan-STARRS1 and WISE: Discovery of Seven Nearby Objects Including Two Candidate Spectroscopic Variables

, 2013
We present initial results from a wide-field (30,000 deg^2) search for L/T transition brown dwarfs within 25 pc using the Pan-STARRS1 and WISE surveys. Previous large-area searches have been incomplete for L/T transition dwarfs, because these objects are

High-resolution Emission Spectroscopy of the Ultrahot Jupiter KELT-9b: Little Variation in Day- and Nightside Emission Line Contrasts

The Astronomical Journal, 2023
The transmission spectrum of the ultrahot Jupiter KELT-9b ( T _eq ∼ 4000 K) exhibits absorption by several metal species. We searched for atomic and molecular lines in its emission spectrum by observing partial phase curves with the Calar Alto high ...

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions

Advanced Materials, EarlyView.
Incorporation of low molecular weight liquid crystals (LC) into liquid crystal elastomers (LCE) leads to a significant increase in their stiffness and output work density. Such remarkable stiffening is attributed to nanoscale phase‐separation and the formation of induced‐smectic domains in polydomain and monodomain LC‐LCEs, respectively.
