Ligand‐Mediated Surface Carrier Modulation in Perovskite Nanocrystals for Charge‐Symmetric LEDs
Advanced Materials, EarlyView.A hydrolysis‐assisted ligand exchange strategy enables surface carrier modulation of perovskite nanocrystals using a multifunctional π‐conjugated ligand. This molecular surface design achieves charge balance and recombination‐zone symmetry in light‐emitting diodes (LEDs), which leads to high‐efficiency perovskite LEDs and establishes a general platform

Securing tropical forest carbon: the contribution of protected areas to REDD [PDF]
, 2010 Forest loss and degradation in the tropics contribute 6-17% of all greenhouse gas emissions. Protected areas cover 217.2 million ha (19.6%) of the world's humid tropical forests and contain c.

Field calibration for multidirectional spectroradiometers
Measurement Science and Technology, 2022 Abstract A mobile calibration system for a multidirectional spectroradiometer (MUDIS) to transfer the absolute radiometric calibration from the laboratory to the location of the outdoor-measurement (field calibrator) has been developed.

Advanced Optical Materials, EarlyView.Degradation in blue MR‐TADF OLEDs originates from high triplet density caused by slow RISC. LDI‐TOF MS directly detects host‐ and emitter‐derived fragments, providing molecular insight into how triplet accumulation drives degradation in the emissive layer. ABSTRACT Blue organic light‐emitting diodes (OLEDs) employing multi‐resonance thermally activated

Spatial metrics in fire ecology: seeking consistency amidst complexity
Biological Reviews, EarlyView.ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...
