Prospects and Challenges of Proton Conducting Cerates in Electrochemical Hydrogen Devices for Clean Energy Systems: A Review

open access: yesGlobal Challenges, EarlyView.
This review paper highlights the current development of cerate‐based proton‐conducting oxides (PCOs) used as an electrolyte in electrochemical devices named hydrogen pumps, hydrogen isotope separation systems, tritium recovery systems, and hydrogen sensors. The challenges and prospects of proton‐conducting cerates are also discussed.

A multi‐proxy record of climate variability during the Loch Lomond Stadial (GS‐1) at Old Buckenham Mere, East England, UK

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the ...

Stratigraphy and geomorphology of Des‐Cubierta Cave (Pinilla del Valle, Madrid, Spain): Geological insights into a Neanderthal symbolic accumulation of large crania

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Des‐Cubierta Cave, part of the Calvero de la Higuera complex, is situated in the intramountainous upper valley of the Lozoya River within the Guadarrama Range. The cave's geological, palaeontological, and archaeological record reveals a complex history of sedimentary and anthropogenic processes spanning hundreds of thousands of years ...
