Structurally Defined Water‐Soluble Metallofullerene Derivatives towards Biomedical Applications
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 A modular metallobuckytrio (MBT) platform provides a family of structurally defined, water‐soluble metallofullerene derivatives that can safely carry rare‐earth elements in tailorable molecules, showing promise in biomedicines including MRI contrast agents and photosensitizers. Abstract Endohedral metallofullerenes (EMFs) are excellent carriers of rare‐

A new set of atmosphere and evolution models for cool T–Y brown dwarfs and giant exoplanets [PDF]
Astronomy & Astrophysics, 2020 We present a new set of solar metallicity atmosphere and evolutionary models for very cool brown dwarfs and self-luminous giant exoplanets, which we term ATMO 2020. Atmosphere models are generated with our state-of-the-art 1D radiative-convective equilibrium code ATMO, and are used as surface boundary conditions to calculate the interior structure and ...

Popular political attitudes in Samoa: Findings of the Pacific Attitudes Survey
Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 408-429, September 2022., 2022 Abstract Popular political attitudes surveys have been conducted globally for several decades, but the Pacific region remains an exception. This paper presents the findings of the first Pacific Attitudes Survey (PAS), conducted in Samoa from December 2020‐January 2021.

Multiple Stellar Populations at Less Evolved Stages. III. A Possible Helium Spread in NGC 2210
The Astrophysical Journal, 2023 Helium variations are common features of globular clusters (GCs) with multiple stellar populations. All the formation scenarios predict that secondary population stars are enhanced in helium, but the exact helium content depends on the polluters ...

Embryonic cranial cartilage defects in the Fgfr3Y367C/+ mouse model of achondroplasia
The Anatomical Record, EarlyView., 2023 Abstract Achondroplasia, the most common chondrodysplasia in humans, is caused by one of two gain of function mutations localized in the transmembrane domain of fibroblast growth factor receptor 3 (FGFR3) leading to constitutive activation of FGFR3 and subsequent growth plate cartilage and bone defects.

JWST Observations of the Enigmatic Y-Dwarf WISE 1828+2650. I. Limits to a Binary Companion
The Astrophysical Journal, 2023 The Y-dwarf WISE 1828+2650 is one of the coldest known brown dwarfs with an effective temperature of ∼300 K. Located at a distance of just 10 pc, previous model-based estimates suggest WISE1828+2650 has a mass of ∼5–10 M _J , making it a valuable ...

THE FIRST DETECTION OF PHOTOMETRIC VARIABILITY IN A Y DWARF: WISE J140518.39+553421.3 [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present the first detection of the photometric variability in a spectroscopically confirmed Y dwarf. The Infrared Array Camera on board the Spitzer Space Telescope was used to obtain time series photometry of WISE J140518.39+553421.3 at 3.6 and 4.5 μm over a 24-hr period at two different epochs separated by 149 days ...

Atmospheric Retrieval Of Cool Y Dwarfs
, 2017 Brown dwarfs' near-infrared spectra contain a wealth of information which can reveal the physical and chemical processes that occur in their atmospheres. Using a recently developed atmospheric retrieval model, we are able to constrain various molecular abundances, along with photometric radius, gravity, cloud optical depths, and temperature profiles ...
