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.

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.

Land Use Simulation of Guangzhou Based on Nighttime Light Data and Planning Policies
This article employs nighttime light (NTL) information as a proxy indicator of gross domestic product(GDP), and a future land use simulation model (FLUS) to simulate the land use patterns in Guangzhou from 2015 to 2018 and 2018 to 2035 by incorporating planning policies. This study demonstrates that NTL is a suitable and feasible proxy indicator of GDP for the land use simulations, providing a scientific basis for the development of urban planning and construction policy.

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.
