The Speciated isoprene emission model with the MEGAN algorithm for China (SieMAC) [PDF]

Geoscientific Model Development
Isoprene is the dominant non-methane Volatile Organic Compound (VOC) emitted from terrestrial ecosystems and plays an important role in ozone chemistry. Understanding isoprene emissions is critical for controlling air pollution. The Model of Emissions of

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Influence of crosslinker on the properties of terpene‐based poly(high internal phase emulsion)s

Polymer International, EarlyView.
Myrcene was polymerized and crosslinked with hydrophilic monomeric and oligomeric dimethacrylates within high internal phase emulsions to produce hierarchically porous bio‐based poly(high internal phase emulsion)s with tuned morphology and mechanical properties.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

Polymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

The production of isoprene from cellulose using recombinant Clostridium cellulolyticum strains expressing isoprene synthase

MicrobiologyOpen, 2020
Isoprene is an important bulk chemical which is mostly derived from fossil fuels. It is used primarily for the production of synthetic rubber. Sustainable, biotechnology‐based alternatives for the production of isoprene rely on the fermentation of sugars

Effects of light and temperature on isoprene emission at different leaf developmental stages of eschweilera coriacea in central Amazon [PDF]

Acta Amazonica, 2014
Isoprene emission from plants accounts for about one third of annual global volatile organic compound emissions. The largest source of isoprene for the global atmosphere is the Amazon Basin. This study aimed to identify and quantify the isoprene emission

Leaf phenology as one important driver of seasonal changes in isoprene emissions in central Amazonia [PDF]

Biogeosciences, 2018
Isoprene fluxes vary seasonally with changes in environmental factors (e.g., solar radiation and temperature) and biological factors (e.g., leaf phenology).

A walk in the park—Identifying healthy greenspaces using scents

PLANTS, PEOPLE, PLANET, EarlyView.
As urbanisation accelerates globally, access to nature is increasingly recognised as vital for public health and wellbeing. We captured and analysed plant‐emitted airborne ‘scent signatures’ across Oxford's urban greenspaces to assess their potential health relevance.
