Quantifying Polar Mesospheric Clouds Thermal Impact on Mesopause

open access: yesAtmosphere
The article is focused on the quantitative assessment of the thermal impact of polar mesospheric clouds (PMCs) on the mesopause caused by the emission of absorbed solar and terrestrial infrared (IR) radiation by cloud particles.

Aircraft observations since the 1990s reveal increases of tropospheric ozone at multiple locations across the Northern Hemisphere

open access: yesScience Advances, 2020
Recent aircraft observations show that tropospheric ozone increased above many Northern Hemisphere regions since the mid-1990s. Tropospheric ozone is an important greenhouse gas, is detrimental to human health and crop and ecosystem productivity, and ...

Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

Fresh air in the 21st century? [PDF]

open access: yes, 2003
Ozone is an air quality problem today for much of the world's population. Regions can exceed the ozone air quality standards (AQS) through a combination of local emissions, meteorology favoring pollution episodes, and the clean-air baseline levels of ...

Photonic Engineering Enables All‐Passive Upconversion Imaging with Low‐Intensity Near‐Infrared Light

open access: yesAdvanced Functional Materials, EarlyView.
A passive upconversion imaging system enables the observation of scenes illuminated by low‐intensity incoherent near‐infrared light from 750 to 930 nm, by converting it into the visible without the use of external power. The upconverter is enabled by triplet–triplet annihilation in a bulk heterojunction, with absorption enhanced by plasmonic resonators

Oxygen-ozone therapy: paradoxical stimulation of ozone

open access: yesOzone Therapy, 2016
After several years of scientific research and accurate clinical practice, the oxygen-ozone therapy continues to represent a method full of prospects and new opportunities. On this basis we present an updated review on basic mechanisms through which the ozone acts.

Assessing the relationship between spectral solar irradiance and stratospheric ozone using Bayesian inference

open access: yes, 2014
We investigate the relationship between spectral solar irradiance (SSI) and ozone in the tropical upper stratosphere. We find that solar cycle (SC) changes in ozone can be well approximated by considering the ozone response to SSI changes in a small ...

Estimating the summertime tropospheric ozone distribution over North America through assimilation of observations from the Tropospheric Emission Spectrometer [PDF]

open access: yes, 2008
We assimilate ozone and CO retrievals from the Tropospheric Emission Spectrometer (TES) for July and August 2006 into the GEOS-Chem and AM2-Chem models.
