Carbon Dots for Cancer Theranostics: Synthesis Strategies, Luminescence Properties, and Advances in Bioimaging‐Guided Diagnosis and Therapy

Chemistry – A European Journal, EarlyView.
Lighting up the path to precision oncology: This review comprehensively summarizes the rational design of carbon dots (CDs), elucidating how core size, surface chemistry, and heteroatom doping dictate their luminescence mechanisms. Special emphasis is placed on engineering NIR‐II emissive CDs for deep‐tissue imaging.

A Volume-limited Sample of Ultracool Dwarfs. II. The Substellar Age and Mass Functions in the Solar Neighborhood

The Astrophysical Journal
We present the most precise constraints to date for the mass and age distributions of single ultracool dwarfs in the solar neighborhood, based on an updated volume-limited sample of 504 L, T, and Y dwarfs within 25 pc.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Boards of Directors That Transform: A Study on How Specific Architectural Components Drive ESG Performance

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores the potential influence of key components of the board of directors' architecture on ESG outcomes. Specifically, we focus on the effects of demographic components (gender and cultural diversity), structural and compositional factors (size, CEO‐Chair separation, and the presence of independent/non‐executive directors), and ...

OGLE-2014-BLG-0221Lb: A Jupiter Mass Ratio Companion Orbiting Either a Late-type Star or a Stellar Remnant

The Astronomical Journal
We present the analysis of the microlensing event OGLE-2014-BLG-0221, a planetary candidate event discovered in 2014. The photometric light curve is best described by a binary-lens single-source model. Our light-curve modeling finds two degenerate models,

Searching for GEMS: Characterizing Six Giant Planets Around Cool Dwarfs

The Astronomical Journal
Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasingly large number of them to enable statistical surveys like the Searching ...
