Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey II: Report of a Community Workshop on the Scientific Synergies Between the SPHEREx Survey and Other Astronomy Observatories [PDF]

, 2018
SPHEREx is a proposed NASA MIDEX mission selected for Phase A study. SPHEREx would carry out the first all-sky spectral survey in the near infrared. At the end of its two-year mission, SPHEREx would obtain 0.75-to-5$ $m spectra of every 6.2 arcsec pixel on the sky, with spectral resolution R>35 and a 5-$ $ sensitivity AB$>$19 per spectral ...

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.

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 use of thermal imaging to assess heat generation during dental implant bed preparation in the presence of a surgical guide with an incorporated coolant channel

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluates the thermodynamic benefits of including an irrigation fluid channel in the design of surgical guides used for dental implant site drilling. Materials and Methods Two types of guides suitable for hosting artificial bone plates that mimic the mechanical properties of human alveolar bone were designed: a classical ...

Looking at Infrared Background Radiation Anisotropies with Spitzer: Large-scale Anisotropies and Their Implications

The Astrophysical Journal Letters
We use Spitzer/IRAC deep-exposure data covering two significantly larger than before sky areas to construct maps suitable for evaluating source-subtracted fluctuations in the cosmic infrared background (CIB).

Model-Independent Diagnostics of Highly Reddened Milky Way Star Clusters: Age Calibration

, 2009
The next generation near- and mid-infrared Galactic surveys will yield a large number of new highly obscured star clusters. Detailed characterization of these new objects with spectroscopy is time-consuming.

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body

Meteoritics &Planetary Science, EarlyView.
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Near-infrared photometry of the young open clusters NGC 1893 and Berkeley 86

, 1999
We present photometry in the J and K near-infrared bands for two regions centered on the young open clusters NGC 1893 and Berkeley 86. We study 700 stars down to K = 17 in the field of NGC 1893, and about 2000 stars in the field of Berkeley 86 down to K$\
