The Characterization and Galactic Distribution of Infrared Dark Clouds
The Astrophysical Journal, 2006 Using 13CO J = 1 ? 0 molecular line emission from the Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey (BU-FCRAO GRS), we have established kinematic distances to 313 infrared dark clouds (IRDCs) by matching the morphology of the molecular line emission in distinct velocity channels to their mid-infrared extinction.

Polarization Holographic 4D Phenotyping Reveals Nanoplastic Induced Dysfunction in Zooplankton
Advanced Science, EarlyView.Contaminant‐induced dysfunction in complex aquatic organisms remains difficult to resolve across scales. Polarization Holographic Imaging Microscopy (PHIM) integrates polarization‐sensitive holography with computational volumetric reconstruction for label‐free phenotyping of zooplankton in natural seawater, revealing that nanoplastic stress drives ...

Advanced Science, EarlyView.This work presents a multifunctional ionic liquid, [SO3H‐PMIm][OTf], that addresses A‐site cation inhomogeneity and lead toxicity in pure‐iodide wide‐bandgap perovskite solar cells. The additive enables homogeneous cation distribution, achieving 22.02% efficiency with 90% retention after 3000 h and reducing lead leakage by over 58%, thereby ...

A Novel Cloud Removal Method Based on IHOT and the Cloud Trajectories for Landsat Imagery
Remote Sensing, 2018 Cloud removal is a prerequisite for the application of Landsat datasets, as such satellite images are invariably contaminated by clouds. Clouds affect the transmission of radiation signal to different degrees because of their different thicknesses ...

Infrared polarimetry in the Rho Ophiuchus dark cloud
The Astronomical Journal, 1979 Infrared polarimetry has been obtained of 16 objects in the proposed region of star formation in the rho Oph dark cloud. This study is used along with visual polarimetry, infrared photometry, and molecular line studies to deduce the cloud morphology around the very young stellar cluster.

Non‐Covalent Reversibly Photoconvertible Fluorescent Tags for Wash‐Free Protein Labeling
Advanced Science, EarlyView.FAST proteins combined with one or two fluorogens undergo reversible fluorescence switching or photoconversion through photoisomerization. At low fluorogen concentration and high light intensity, they act as negative or positive photoswitchers and photoconvertible tags, which are promising for discriminating FAST variants.
