Financing the Commune

open access: yesJahrbuch für Wirtschaftsgeschichte
The connection between public spending and the ambitions of urban elites is a common topic in the historiography of the late Middle Ages. However, it is still unclear how city finances and private capital interacted before the use of sophisticated ...

Overcoming Hole‐Extraction Barriers: A Facile PEDOT:PSS Interlayer Unlocks Record‐Low Voltage Deficit in PbS Quantum Dot Solar Cells

open access: yesAdvanced Science, EarlyView.
A synergistic methanol and oxalic acid interface engineering strategy is developed for PbS quantum dot solar cells. This approach transforms the PEDOT:PSS layer into a dense, electronically uniform, and conductive network. Consequently, the device achieves a record‐low voltage deficit of 340 mV, yielding a remarkable Voc of 742 mV and a power ...

Towards Climate Neutrality by 2050: Role of Aluminum for Short‐ and Long‐Term Energy and Hydrogen Storage

open access: yesAdvanced Energy Materials, EarlyView.
The Aluminum energy storage cycle involves the use of renewable energy for Al production and the generation of heat (dry cycle) and heat and H2 (wet cycle) for energy production via Al‐steam combustion. ABSTRACT Reaching climate neutrality by 2050 requires innovative long‐term energy storage (LTES) solutions beyond the current use of fossil fuels ...

Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...
