Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Ion‐Regulating Membranes with Surface‐Enriched Charge Networks Enabling Stable Zinc‐Manganese Flow Batteries

open access: yesAdvanced Materials, EarlyView.
An ion‐regulating membrane is designed with a surface‐concentrated positively‐charged Zn2⁺ crosslinked network for zinc‐manganese flow batteries. The membrane effectively mitigates proton crossover and regulates zinc ion distribution to avoid dendrites, thus significantly improving areal capacity and prolonging the lifespan with a record accumulated ...

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

open access: yesAdvanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics

open access: yesAdvanced Materials, EarlyView.
Aqueously upcycled lignin is transformed into a printable ink that self‐assembles into a nanotextured surface during printing with the highest reported biopolymer‐based tribonegativity. The resulting skin‐integrated triboelectric sensor enables high‐fidelity cardiovascular monitoring and objective mental workload classification, demonstrating a ...

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes

open access: yesAdvanced Materials, EarlyView.
Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

Sovereign Immunity for Rent: How the Commodification of Tribal Sovereign Immunity Reflects the Failures of the U.S. Patent System [PDF]

open access: yes, 2019
Last year, a Fortune 500 pharmaceutical company attempted to rent the sovereign immunity of an American Indian tribe in order to shield its patents on a dry-eye drug from invalidation by generic competitors in inter partes review.
