Enhanced Formation of Dicarboxylic Acids in the Catalytic Oxidation of Polyethylene With O2 and NOx

open access: yesAngewandte Chemie, EarlyView.
The oxidation of polyethylene in the presence of a mixture of O2 and NOx and with Cu2+/V5+ as catalyst yields ∼51 mol% diacids, while retaining ∼80 mol% of the carbon in the oil fraction. The developed method is robust and tolerates several polymer types as well as impurities.

Vapor‐Phase Grain‐Boundary Anchoring Enables Molecular Toughening and Record Bending Endurance in Pilot‐Scale Roll‐to‐Roll‐Printed Flexible Perovskite Modules

open access: yesAngewandte Chemie, EarlyView.
A vapor‐phase molecular toughening strategy is developed for pilot‐scale roll‐to‐roll (R2R) ‐compatible fabrication of flexible perovskite solar modules. Thiol vapor selectively regulates crystallization and anchors at grain boundaries, reducing defects while enhancing mechanical resilience.

Strain Engineering via W–O–Ru Interfacial Coupling to Suppress Lattice Oxygen Activation for Stable Acidic Water Electrolysis

open access: yesAngewandte Chemie, EarlyView.
Constructing atomically coupled W–O–Ru interfacial units on RuO2 triggers a dynamic strain evolution during the oxygen evolution reaction. An initial tensile strain secures structural stability, while a self‐adjusting transition to interfacial compression optimizes catalytic activity.

THE SECOND ECUMENICAL COUNCIL AND THE SECOND ROME

Византийский временник = ΒΥΖΑΝΤΙΝΑ ΧΡΟΝΙΚΑ
Целью статьи является определить, как идея Второго Рима оказалась воплощенной в решениях Второго Вселенского собора, благодаря стремлению императора Феодосия Великого сделать Константинополь своей столицей. До 80-х гг. IV в. идея Нового Рима применительно к Константинополю оставалась неоформленной, а сам город не являлся ни столицей, ни религиозным ...
