Advanced Science, EarlyView.A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Advanced Science, EarlyView.We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

High‐Density‐Cluster Ru Catalyst Substitute for Pt/C Benchmark Improves Membrane Water Electrolysis
Advanced Science, EarlyView.Yuan et al. report a high‐density, monodispersed Ru cluster catalyst featuring interfacial covalent bonds that modulate the electronic structure and optimize intermediate adsorption–desorption, thereby conferring pH‐universal HER activity with ampere‐level current densities and enabling the development of Pt‐free membrane electrodes.

Toward Practical Zn‐Ion Batteries Through Separator/Electrolyte Co‐Design
Advanced Science, EarlyView.A hybrid organic–aqueous electrolyte enables thin commercial polypropylene separators to replace bulky glass‐fiber separators in practical Zn‐ion batteries. This electrolyte/separator co‐design improves wettability, promotes uniform Zn plating/stripping, and suppresses hydrogen evolution, resulting in 4360 h of symmetric‐cell cycling and stable Zn//NVO

Hydrogen Production from Ammonia Electrochemical Cracking
Advanced Science, EarlyView.NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.
