Synthesis of Core–Shell Te@Se Quantum Dots and Their Broadband Photodetector Performance in Low Concentration Electrolytes

Laser &Photonics Reviews, EarlyView.
Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

A Data-driven Approach for Mitigating Dark Current Noise and Bad Pixels in Complementary Metal Oxide Semiconductor Cameras for Space-based Telescopes

The Astronomical Journal
In recent years, there has been a gradual increase in the performance of complementary metal oxide semiconductor (CMOS) cameras. These cameras have gained popularity as a viable alternative to charge-coupled device cameras in a wide range of applications.

Site‐Engineered Corundum‐Structured Aesthetic Composites for Alleviating Heat Accumulation to Mitigate Urban Heat Islands

Small, EarlyView.
ABSTRACT Urban heat islands have become a global issue, as they severely impact several key factors, including elevated energy consumption, increased air pollution and greenhouse gas emissions, compromised human health and comfort, and reduced water quality.

The Mega-MUSCLES Treasury Survey: X-Ray to Infrared Spectral Energy Distributions of a Representative Sample of M Dwarfs

The Astrophysical Journal
We present 5–1 × 10 ^7 Å spectral energy distributions (SEDs) for 12 M dwarf stars covering spectral types M0–M8. Our SEDs are provided for community use as a sequel to the Measurements of the Ultraviolet Spectral Characteristics of Low-mass Exoplanetary

Things at Work: How Things Contribute to Performing Work

Journal of Management Studies, EarlyView.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.

Star Formation at z=2.481 in the Lensed Galaxy SDSS J1110+6459: Star Formation down to 30 parsec scales

, 2017
We present measurements of the surface density of star formation, the star-forming clump luminosity function, and the clump size distribution function, for the lensed galaxy SGAS J111020.0+645950.8 at a redshift of z=2.481.

Microbial Endolithic Community at Meteor Crater

Meteoritics &Planetary Science, EarlyView.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.
