Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

Advanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.

Star formation in metal-poor gas clouds

, 2012
Observations of molecular clouds in metal-poor environments typically find that they have much higher star formation rates than one would expect based on their observed CO luminosities and the molecular gas masses that are inferred from them.

Energy Band Alignment and Electro‐Optical Behavior of Nearly Unstrained Monolayer MoS2 Heterostructures With GaN

Advanced Materials Interfaces, EarlyView.
Large size (∼100 µm) monolayer MoS2 grown by LPI‐CVD on n‐GaN exhibit a high n‐type doping, very low strain, and a type‐I band alignment at MoS2/GaN interface. Photocurrent measurements under illumination with photon energies from ∼2 to ∼5 eV show superior electro‐optical performances of these MoS2/n‐GaN heterojunctions as compared to Ni/n‐GaN devices ...

One‐Step Fabrication of Highly Transparent Superhydrophobic Coatings Via Atmospheric Pressure Radio Frequency Plasma Deposition

Advanced Materials Interfaces, EarlyView.
Atmospheric‐pressure RF plasma deposition enables the fabrication of transparent, superhydrophobic coatings with anti‐reflective functionality. Process optimization yields high optical transmittance, robust environmental stability, and self‐cleaning properties.

On the Roles of Gravity, Turbulence, and the Magnetic Field in Angular Momentum Transfer within Molecular Clouds

The Astrophysical Journal
Observations of molecular structures on scales of ∼0.1−50 pc show that the specific angular momentum ( j ) scales with radius ( R ) as j  ∼  R ^3/2 .

Global Collapses and Expansions in Star-Forming Clouds

, 2009
Spectral molecular line profile observations of star-forming molecular clouds sometimes show distinct red asymmetric double-peaked molecular line profiles with weaker blue peaks and stronger red peaks.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.
