π‐Bridge Engineering of Nonfullerene Acceptors for Organic Photodiodes: Extension of the Near Infrared Response Beyond 1200 nm

Advanced Functional Materials, EarlyView.
A π‐bridge engineering strategy enhances intramolecular charge transfer, enabling non‐fullerene acceptors to extend near‐infrared absorption beyond 1200 nm. The resulting organic photodiodes exhibit high detectivity and fast response. These high‐performance devices demonstrate practical potential in photoplethysmography and optical wireless ...

A Holistic Exploration of the Potentially Recoverable Redshift Information of Stage IV Galaxy Surveys

The Astrophysical Journal
Extragalactic science and cosmology with Stage IV galaxy surveys will rely almost exclusively on redshift measurements derived solely from photometry, which are subject to systematic and statistical uncertainties with numerous analysis choices.

Local Redshift Surveys and Galaxy Evolution [PDF]

, 2006
We present observations of galaxy environmental dependencies using data from the 2dF Galaxy Redshift Survey. From a combined analysis of the luminosity function, Butcher-Oemler effect and trends in H$ $ line strengths we find support for a model where galaxy properties are mainly set by initial conditions at the time of their formation.

Characterizing and Propagating Modeling Uncertainties in Photometrically-Derived Redshift Distributions

, 2011
The uncertainty in the redshift distributions of galaxies has a significant potential impact on the cosmological parameter values inferred from multi-band imaging surveys.

Ce3+‐Activated Lithium Rare‐Earth Oxonitridolithosilicates: A New Class of LED Phosphors with Similarities to Garnets

Advanced Functional Materials, EarlyView.
Garnet‐like luminescence upon Ce3+‐activation is found in the first six representatives Li9RESi4N4O8 (RE = Y, La, Gd, Dy, Yb, Lu) of the substance class of lithium rare‐earth oxonitridolithosilicates, which also show a novel structure type. High‐temperature solid‐state synthesis yielded crystalline samples for single‐crystal X‐ray diffraction‐based ...

Semiconducting Polymer Nanoparticles as Multimodal Agents for Optical and Magnetic Resonance Imaging

Advanced Healthcare Materials, EarlyView.
Semiconducting polymer nanoparticles (SPNs) exhibit many advantageous optical and biological properties. Multimodal SPN‐based contrast agents that integrate several imaging modalities yield a wealth of information through the use of different imaging mechanisms.

DESIVAST: Catalogs of Low-redshift Voids Using Data from the DESI Data Release 1 Bright Galaxy Survey

The Astrophysical Journal
We present three separate void catalogs created using a volume-limited sample of the DESI Data Release 1 Bright Galaxy Survey. We use the algorithms VoidFinder and V ^2 to construct void catalogs out to a redshift of z = 0.24. Excluding voids affected by
