Phase behaviour and conductivity study of electrolytes in supercritical hydrofluorocarbons

, 2011
The purpose of this work was to characterise supercritical hydrofluorocarbons (HFC) that can be used as solvents for electrodeposition. The phase behaviour of CHF3, CH2F2, and CH2FCF3 containing [NBun4][BF4], [NBun4][B{3,5-C6H3(CF3)2}4] and Na[B{3,5-C6H3(

Simulating Agroecology Policy Options for the Resilience of Smallholder Food Security to Climate Shocks

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Climate shocks and the agroecology–resilience nexus of smallholders. Summary of key findings: Agroecology increases smallholder resilience capacity by 8.7% in the short term under a decreased rainfall scenario, a projected 11% decline in precipitation reduces resilience by 5.6% and 14.2% in the short and long terms, respectively, and a policy‐induced ...

Early action on HFCs mitigates future atmospheric change

Environmental Research Letters, 2016
As countries take action to mitigate global warming, both by ratifying the UNFCCC Paris Agreement and enacting the Kigali Amendment to the Montreal Protocol to manage hydrofluorocarbons (HFCs), it is important to consider the relative importance of the ...

Global emissions and abundances of chemically and radiatively important trace gases from the AGAGE network [PDF]

Earth System Science Data
Measurements from the Advanced Global Atmospheric Gases Experiment (AGAGE) combined with a global 12-box model of the atmosphere have long been used to estimate global emissions and surface mean mole fraction trends of atmospheric trace gases.

Clathrate hydrate crystallization

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5931-5953, November 2026.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

Atmospheric Chemistry of CF3C(Cl)═CH2 (HCFO‐1233xf)

International Journal of Chemical Kinetics, Volume 58, Issue 11, Page 943-953, November 2026.
ABSTRACT 2‐chloro‐3,3,3‐trifluoropropene, CF3C(Cl)═CH2 (HCFO‐1233xf), is a volatile hydrochlorofluoroolefin, commonly used in industrial synthesis of other halogenated olefins. Kinetics and reaction mechanisms for the reactions of OH radicals, Cl atoms, and O3 with CF3C(Cl)═CH2 were investigated using FTIR/smog chamber studies in 700 Torr of air/N2 ...

Aiouea riedeliana comb. nov. (Lauraceae) from Brazil, with an amended description and provisional extinction threat assessment

Nordic Journal of Botany, Volume 2026, Issue 10, October 2026.
Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

Linking Oxide Scale Evolution to Thermal Shock Failure in Zirconium Carbide

International Journal of Applied Ceramic Technology, Volume 23, Issue 5, October 2026.
ABSTRACT Zirconium carbide (ZrC) is an ultra‐high‐temperature ceramic valued for its excellent thermomechanical properties, yet its vulnerability to oxidation and its thermal shock behavior upon oxidation remain insufficiently understood. This study examines how prior oxidation history, defined by cyclic exposure temperature and duration, affects the ...

6FDA-polyimide thin-film composite hollow fiber membranes for hydrofluorocarbons and CO2 separations [PDF]

Herein, high molecular weight fluorinated aromatic polyimides were assessed for the first time to recover difluoromethane (R-32) from its blends with other hydrofluorocarbons and hydrofluoroolefins (R-134a: 1,1,1,2-tetrafluoroethane, R-125 ...
