Light on the sustainable preparation of aryl-cored dibromides

Beilstein Journal of Organic Chemistry
Both aryl and benzyl polybromides have gained significant importance as reactive building blocks in polymer and materials chemistry. Their preparation primarily relies on established synthetic methods using molecular bromine or N-bromosuccinimide, known ...

Graphite intercalation compound with iodine as the major intercalant [PDF]

Halogenated CBr(sub x)I(sub y) (1 less than y/x less than 10) was made by exposing graphite materials with interplanar spacing in the 3.35 to 3.41 A range to either pure Br2 or an I2-Br2 mixture, and then to iodine vapor containing a small amount of Br2.

Single‐Step Conversion of Metal Impurities in CNTs to Electroactive Metallic Nitride Nanoclusters for Electrochemical CO2 Reduction

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.
A single‐step, low‐temperature co‐pyrolysis process removes encapsulated seed metal NPs (10–50 nm) from CNTs, redistributing them as surface‐anchored metal and metal–nitride NCs (1–1.5 nm). Herein, Ni3N NCs achieve an ultra‐low onset overpotential for CO2 reduction to CO with >98% Faradaic efficiency across 100–700 mA cm−2.

Myeloperoxidase Luminol Reaction – A Novel Faecal Assay for Predicting Colonoscopy Findings in Patients with Ulcerative Colitis: A Pilot Cross‐Sectional Clinical Study

Advanced Healthcare Materials, Volume 15, Issue 1, 9 January 2026.
Can luminol detect faecal inflammation? This study explores the development and optimisation of a rapid novel assay ‐ Myeloperoxidase Luminol Reaction (MPOLR) for the detection of faecal myeloperoxidase activity. This simple and rapid luminol‐based approach competes with clinically validated faecal biomarkers in predicting endoscopic findings in ...

Noncovalent Binding of the Halogens to Aromatic Donors. Discrete Structures of Labile Br\u3csub\u3e2\u3c/sub\u3e Complexes with Benzene and Toluene [PDF]

, 2001
Precise molecular structures resulting from the noncovalent interaction of Br2 with benzene (and toluene) reveal the unusual localized bonding to specific (one or two) carbon centers in prereactive complexes leading directly to the transition states for ...
