Shortwave Infrared Light Detection and Ranging Using Silver Telluride Quantum Dots

open access: yesAdvanced Materials, EarlyView.
Post‐synthesis surface engineering and doping control significantly improve the performance of Ag₂Te CQD photodiodes, achieving a low dark current of 450 nA cm−2 at −0.5 V, an LDR exceeding 150 dB, and a rapid response speed of ≈25 ns. A proof‐of‐concept LiDAR demonstration in the SWIR using a nanosecond diode laser, achieves decimetre‐level resolution

Automated Quality Control Scheme for GPM Satellite Precipitation Products

open access: yesGeophysical Research Letters
The constellation approach underpinning precipitation products such as the Integrated Multi‐satellitE Retrievals for GPM (IMERG) is key to achieving high resolution, but the use of data from multiple sources can unintentionally incorporate instrumental ...

Suspension Electrolytes with Catalytically Self‐Expediating Desolvation Kinetics for Low‐Temperature Zinc Metal Batteries

open access: yesAdvanced Materials, EarlyView.
The CeO2‐x‐suspension electrolyte is initially proposed to regulate the Zn[(H2O)6]2+ solvation structure and alters the inner Helmholtz plane to accelerate Zn[(H2O)6]2+ desolvation, achieving a homogenized electric field and uniform ion flux kinetics.
