Assessing Total and Tropospheric Ozone via IKFS-2 Infrared Measurements on Meteor-M No. 2

Atmosphere
Stratospheric ozone shields life on Earth from harmful ultraviolet radiation and plays a crucial role in climate formation, while tropospheric ozone is a pollutant and greenhouse gas.

Membrane‐aided simultaneous reaction–separation for liquid phase products

AIChE Journal, EarlyView.
Abstract Conventionally, reaction and separation are conducted as separate steps in liquid‐phase manufacturing, with products formed during reaction and subsequently separated from unreacted reagents, solvents, and byproducts. Integrating these steps into a simultaneous reaction–separation process can improve efficiency and reduce costs.

The vertical distribution of ozone instantaneous radiative forcing from satellite and chemistry climate models [PDF]

, 2011
We evaluate the instantaneous radiative forcing (IRF) of tropospheric ozone predicted by four state-of-the-art global chemistry climate models (AM2-Chem, CAM-Chem, ECHAM5-MOZ, and GISS-PUCCINI) against ozone distribution observed from the NASA ...

Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

American Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Separation and Valorization of Chlorine From Tail Gas Streams

Angewandte Chemie International Edition, EarlyView.
A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

Intercomparison of Total Column Ozone Between Ozonesonde Observations and Multi-source Products Across 4 Regions

应用气象学报
The intercomparison of vertically integrated total ozone columns (Ωo) derived from 212 CYT-1 ozonesonde observations is conducted at 4 representative Chinese sites: Altay (Xinjiang, 47.7°N), Nenjiang (Heilongjiang, 49.1°N), Shanghai (31.4°N), and Sanya ...

Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment

Advanced Physics Research, EarlyView.
Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...

An operational method for forecasting total column ozone for Punta Arenas, Chile

Meteorological Applications, 2002
AbstractOwing to the decrease of stratospheric ozone during the southern spring (starting in September), the city of Punta Arenas (53.1°S, 70.9°W) and its surroundings are exposed to a high incidence of ultra‐violet‐B (UV‐B) radiation during this period. Ozone denatures DNA, and prolonged exposure may cause skin carcinoma and cataracts.

Operationalizing BioSSbD: A safe‐and‐sustainable‐by‐design framework for biorefineries

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biorefineries are central to the transition toward a circular bioeconomy; however, their increasing scale and technological heterogeneity, and the integration of biological, chemical, and thermochemical processes introduce complex challenges related to safety, sustainability, and operational reliability.
