Ultra‐Thick Carbon Microhoneycomb Cathode for High‐Capacity Lithium‐Oxygen Batteries
Carbon Energy, EarlyView.This work demonstrates ultra‐thick biochar‐derived carbon microhoneycomb cathodes for lithium‐oxygen batteries. The penetrated macrochannels serve as highly efficient pathways for Li+ and O2 and provide abundant accommodation space for the discharge product. The optimized cathode achieved a high areal capacity of 38.2 mAh cm–2, providing guidelines for

Carbon-catalyzed oxidation of SO2 by NO2 and air [PDF]
A series of experiments was performed using carbon particles (commercial furnace black) as a surrogate for soot particles. Carbon particles were suspended in water, and gas mixtures were bubbled into the suspensions to observe the effect of carbon ...

(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3
Chemistry – A European Journal, EarlyView.The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

Chemistry – A European Journal, EarlyView.In situ phenoxide formation at the benzene terminus triggers room‐temperature conversion of thia[6]helicene S,S‐dioxides to coronene. The solubility contrast drives product precipitation, enabling isolation by simple filtration. This pericyclic annulation between the helical termini provides direct access to coronene‐type planar architectures ...

Economic instruments and institutional constraints: possible schemes for SO2 emissions trading in the EU [PDF]
The three proposals examined here were specifically conceived to address the two major constraints by which the institutional context of the EU and UNECE SO2 requirements have been interpreted: national emission ceilings and deposition constraints for ...

Chemistry – A European Journal, EarlyView.Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
