Development and Characterization of Thermo‐Responsive Shape Memory Composite of Polybenzoxazine and Modified Ultrafine Fully Vulcanized Natural Rubber (UFPNR) Filler

open access: yesSPE Polymers, Volume 7, Issue 4, October 2026.
Tough Thermo‐Responsive Composite from PBA‐a and Monomer Grafted UFPNR. ABSTRACT In this study, various types and concentrations of ultrafine fully vulcanized powdered natural rubbers (UFPNR) were evaluated on how they affect the toughness of bisphenol A polybenzoxazine (PBA‐a).

Effect of chemical degradation on fluxes of reactive compounds – a study with a stochastic Lagrangian transport model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
In the analyses of VOC fluxes measured above plant canopies, one usually assumes the flux above canopy to equal the exchange at the surface. Thus one assumes the chemical degradation to be much slower than the turbulent transport.

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3142-3158, September 2026.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...

Rapid formation of isoprene photo-oxidation products observed in Amazonia [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Isoprene represents the single most important reactive hydrocarbon for atmospheric chemistry in the tropical atmosphere. It plays a central role in global and regional atmospheric chemistry and possible climate feedbacks.

Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

open access: yesPlant, Cell &Environment, Volume 49, Issue 9, Page 7168-7190, September 2026.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

Multiphase and Heterogeneous O3 Chemistry on Aerosol and Infrastructural Surfaces Drives Cl2 Sources in a Coastal City

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Molecular chlorine (Cl2) is a key source of chlorine atoms (Cl∙) in the atmosphere, which can alter local oxidation chemistry and enhance both ozone (O3) and particulate matter. While Cl2 levels in some coastal cities can be substantial and are enhanced by particulate nitrate, the presence and impact of Cl2 in US cities is poorly understood ...

The Influence of Aged Smoke on Urban Ozone: Aircraft Measurements in Chicago During the 2023 Canadian Wildfires

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract As large wildfires become more frequent and severe in North America due to heightened fuel aridity and fire weather conditions driven by anthropogenic climate change, wildfire smoke has an increasingly important influence on air quality. Transported smoke can impact urban boundary layer ozone (O3) directly, via the entrainment of O3 formed in ...

Effects of 1,3-Butadiene, Isoprene, and Their Photochemical Degradation Products on Human Lung Cells

open access: yesEnvironmental Health Perspectives, 2004
Because of potential exposure both in the workplace and from ambient air, the known carcinogen 1,3-butadiene (BD) is considered a priority hazardous air pollutant. BD and its 2-methyl analog, isoprene (ISO), are chemically similar but have very different toxicities, with ISO showing no significant carcinogenesis.

Flanking‐Group Engineering Unlocks Emerging Functionalities in Diketopyrrolopyrrole Semiconductors

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
This review presents a comprehensive and unified perspective of flanking‐group engineering in Diketopyrrolopyrrole (DPP) based organic semiconductors that connects molecular‐level design with cross‐device functionalities. By integrating insights from molecular design, solid‐state packing, and device physics, this review seeks to establish general ...
