Surface‐Engineered ZnO Nanoparticles via Acetone Immersion for Charge‐Balanced High Resolution Full‐Color Organic Light Emitting Diode Displays

open access: yesSmall, EarlyView.
Acetone post‐immersion of OLEDs effectively passivates oxygen vacancies in the ZnO electron transport layer, reducing charge trapping and enhancing electron injection. This improves hole‐blocking at the interface and decreases exciton quenching in the emission layer, resulting in significantly enhanced electrical and optical device performance ...

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Urban, Forest, and Agricultural AIS Data: Fine Spectral Structure [PDF]

open access: yes, 1985
Spectra acquired by the Airborne Imaging Spectrometer (AIS) near Lafayette, IN, Ely, MN, and over the Stanford University campus, CA were analyzed for fine spectral structure using two techniques: the ratio of radiance of a ground target to the radiance ...
