Band‐tail and deep trap states are effectively disentangled through the use of selective alkylamine additives. PA‐driven 2D ordering narrows band tails, while HA enhances halide passivation and Pb coordination to suppress deep traps. A comparative study of their CQD short‐wave infrared (SWIR) photodetectors further reveals whether band‐tail states or ...

SET-E: The Search for Extraterrestrial Environmentalism [PDF]
There is currently no evidence for life on any known exoplanet. Here, we propose a form of "galactic anthropology" to detect not only the existence of life on transiting exoplanets, but also the existence of environmentalism movements.

Blue organic light‐emitting diodes (OLEDs) comprising triplet‐harvesting emitters require the use of high‐triplet‐energy hosts and blocking layers to confine the triplet excitons to the emitter. Here, we present efficient single‐layer blue hyperfluorescent OLEDs comprising solely of a matrix‐free emissive layer between two charge‐injecting electrodes ...

Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites
ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...

CANOZE measurements of the Arctic ozone hole [PDF]
In CANOZE 1 (Canadian Ozone Experiment), a series of 20 ozone profile measurements were made in April, 1986 from Alert at 82.5 N. CANOZE is the Canadian program for study of the Arctic winter ozone layer. In CANOZE 2, ozone profile measurements were made

This study presents a dual‐passivating additive‐based synergetic solid‐state halide exchange (DASH) process using chlorodiphenylphosphine (CDPP), which passivates undercoordinated Pb2+ sites and releases chloride ions for uniform halide exchange. The DASH process enhances halide homogeneity and PLQY, enabling bright and spectrally stable deep‐blue ...

When Will the Antarctic Ozone Hole Recover? [PDF]
The Antarctic ozone hole demonstrates large-scale, man-made affects on our atmosphere. Surface observations now show that human produced ozone depleting substances (ODSs) are declining. The ozone hole should soon start to diminish because of this decline.

Nanoimprinted DMD Electrodes Enabling Bidirectional Viewing OLEDs With Quasi Lambertian Emission
We present a dual‐approach strategy for high‐performance bidirectional‐viewing OLEDs, combining enhanced cavity resonance with a nanoimprinted dielectric/metal/dielectric (DMD) electrode. This bidirectional viewing OLED presents an 89.7% enhanced electrode transmittance, a balanced bidirectional emission ratio with 67.3% total brightness increase, as ...

ANTARCTIC OZONE HOLE AS A NATURAL GEOPHYSICAL OBJECT
Satellite data on total ozone content for 1985-2015 have been used. Methods of evaluating ozone deficit in the polar region and its excess in middle latitudes of the Southern Hemisphere have been developed. In early spring the ozone molecules outflow and
