Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

open access: yesChemSusChem, EarlyView.
Chlorine is essential for the production of plastics and pharmaceuticals but poses significant safety and environmental risks. Herein, processes are presented that substitute chlorine or reduce its demand. Where indispensable, trichloride‐ and bichloride‐based ionic liquids could enhance safety and streamline the integration of renewable energy ...

A Greener and More Scalable Synthesis of Biogenic Polydisulfides from Lipoic Acid

open access: yesChemSusChem, EarlyView.
Lipoic acid is an economical and biogenic feedstock for synthesizing recyclable polydisulfides possessing unique properties. Herein, we report a greener and more scalable synthesis of lipoate ester monomers and their corresponding polymers that is backed by life cycle assessment (LCA).

Discovery of Late Holocene‐aged Acropora palmata reefs in Dry Tortugas National Park, Florida, USA: The past as a key to the future?

open access: yesThe Depositional Record, EarlyView.
Emblematic of global coral‐reef ecosystem decline, the coral ecosystem‐engineer Acropora palmata is now rare throughout much of the western Atlantic. We report for the first time, a significant record of late‐Holocene A. palmata populations that existed from ~4500 to 375 years before present in the Dry Tortugas, FL, USA.

Shifting baselines of coral‐reef species composition from the Late Pleistocene to the present in the Florida Keys

open access: yesThe Depositional Record, EarlyView.
We produced the first reconstruction of the coral species composition of MIS5d–a reefs in the Florida Keys and compared it with existing regional records from MIS5e, the Holocene, the recent past (1996) and the present (2022) to evaluate how Florida's reefs changed throughout the late Quaternary.
