Climate Metrics for C1–C4 Hydrofluorocarbons (HFCs) (open access)

Climate Metrics for C1–C4 Hydrofluorocarbons (HFCs)

This article looks at hydrofluorocarbons (HFCs) which are potent greenhouse gases that are potential substitutes for ozone depleting substances. The Kigali amendment lists 17 HFCs that are currently in commercial use to be regulated under the Montreal Protocol. Future commercial applications may explore the use of other HFCs, most of which currently lack an evaluation of their climate metrics. In this work, atmospheric lifetimes, radiative efficiencies (REs), global warming potentials (GWPs), and global temperature change potentials (GTPs) for all saturated HFCs with fewer than 5 carbon atoms are estimated to help guide future usage and policy decisions.

Systemic signaling during abiotic stress combination in plants

Article reveals that plants can integrate different local and systemic signals generated during conditions of stress combination. Furthermore, results show that the specific part at which plants sense the two co-occurring stresses makes a significant difference in how fast and efficient they acclimate.

Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction (open access)

Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction

Authors of the article assert that rate coefficients, k1(T), for the gas-phase reaction of the OH radical with Furan-2,5-dione (maleic anhydride (MA), C4H2O3), a biomass burning related compound, were measured under pseudo first-order conditions in OH using the pulsed laser photolysis - laser induced fluorescence method over a range of temperature and bath gas pressure. Their results are compared with a previous room temperature relative rate study of the OH + MA reaction and significant discrepancy between the studies is discussed. This is the accepted manuscript version of the published article.

Dual activity of anthocyanidin reductase supports the dominant plant proanthocyanidin extension unit pathway

This article presents research on genetic and biochemical analyses that shows ANR has dual activity and is involved not only in the production of (−)-epicatechin starter units but also in the formation of 2,3-cis-leucocyanidin to serve as (−)-epicatechin extension units. The results find that differences in the product specificities of ANRs account for the presence/absence of PA polymerization and the compositions of PAs across plant species
