Syntheses and Properties of Pentafluoroethylplumbanes in the Oxidation States +II, +III, and +IV

Chemistry – A European Journal, EarlyView.
Syntheses of pentafluoroethyl substituted plumbanes in the formal oxidation states +II, +III, and +IV are reported. The compounds were characterized by multinuclear NMR spectroscopy, including 207Pb NMR spectroscopy, mass spectrometry and single‐crystal x‐ray diffraction experiments. ABSTRACT Mono‐, bis‐, and tris(pentafluoroethyl)plumbanes of the type

Bismuth Chalcogenide‐Based Photocatalysts for Nitrogen Reduction: Recent Progress and Prospects

Chemistry – A European Journal, EarlyView.
Bismuth chalcogenides emerge as promising visible‐light photocatalysts for sustainable ammonia synthesis, driven by tunable electronic structures and strong N2 activation. Recent advances reveal how defects, doping and heterojunction design synergistically enhance charge separation and reactivity. Key challenges and future directions highlight pathways

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C
