Protocol for the development of the Master Chemical Mechanism, MCM v3 (Part A): tropospheric degradation of non-aromatic volatile organic compounds [PDF]

open access: yesAtmospheric Chemistry and Physics, 2003
Kinetic and mechanistic data relevant to the tropospheric degradation of volatile organic compounds (VOC), and the production of secondary pollutants, have previously been used to define a protocol which underpinned the construction of a near-explicit ...

Metathesis Transformations of Natural Products: Cross-Metathesis of Natural Rubber and Mandarin Oil by Ru-Alkylidene Catalysts

open access: yesMolecules, 2012
This study reports on the degradation of natural rubber (NR) via cross-metathesis with mandarin oil and <em>d</em>-limonene, an abundant compound in essential oils; that were used as chain transfer agents (CTAs) and green solvents.

From Static to Spatiotemporal: Dynamic Volatility Distribution Parameterizations for Global Organic Aerosol Simulations

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Organic aerosols (OA) are a major component of fine particulate matter that affects air quality and climate, yet atmospheric models often underestimate their concentrations, partly reflecting uncertainties in the assumed volatility distribution of primary organic aerosol emissions.

Gas/particle partitioning of carbonyls in the photooxidation of isoprene and 1,3,5-trimethylbenzene [PDF]

open access: yesAtmospheric Chemistry and Physics, 2008
A new denuder-filter sampling technique has been used to investigate the gas/particle partitioning behaviour of the carbonyl products from the photooxidation of isoprene and 1,3,5-trimethylbenzene. A series of experiments was performed in two atmospheric

Overview of Aerosols in the E3SM Version 3: New Model Features and Their Impacts

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Accurate and comprehensive representation of aerosols in Earth system models (ESMs) is critical for modeling radiative forcing and seasonal‐to‐decadal variability. With increasing computing power, detailed physical and chemical processes representing aerosols and their interactions with other components of the Earth system can be treated more ...

Carotenoids From Amazonian Fruits as Functional Pigments in Active and Intelligent Food Packaging: Materials, Stability, and Technological Performance

open access: yesJournal of Food Science, Volume 91, Issue 8, August 2026.
ABSTRACT Amazonian fruits represent an underexplored source of carotenoids with high technological, functional, and economic potential for applications in food packaging. In recent years, active and intelligent packaging systems based on biopolymers and natural pigments have emerged as effective strategies for extending shelf life, monitoring food ...

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...

Extreme weather exacerbates ozone pollution in the Pearl River Delta, China: role of natural processes [PDF]

open access: yesAtmospheric Chemistry and Physics
Ozone (O3) pollution research and management in China have mainly focused on anthropogenic emissions, while the importance of natural processes is often overlooked. With the increasing frequency of extreme weather events, the role of natural processes in

Impacts of Maritime Continent Forest and Peat Fires on Regional Air Quality During 2019 CAMP2Ex Using MUSICAv0

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The NASA Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex) field campaign from 24 August to 05 October 2019 observed a complex mixture of aerosols—biomass burning smoke transported from Maritime Continent (MC)/Indonesia fires to the Philippines and Metro Manila's urban pollution.

The continental source of glyoxal estimated by the synergistic use of spaceborne measurements and inverse modelling [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Tropospheric glyoxal and formaldehyde columns retrieved from the SCIAMACHY satellite instrument in 2005 are used with the IMAGESv2 global chemistry-transport model and its adjoint in a two-compound inversion scheme designed to estimate the continental ...
