A Critical Review on Nitrogen Control in the Scrap‐Based Electric Arc Furnace Steelmaking Route to Produce Low‐Nitrogen Steels

steel research international, EarlyView.
In primary electric arc furnace (EAF) steelmaking, carbon boiling removes nitrogen from liquid steel and sustains slag foaming. In 100% scrap‐ or hydrogen direct reduced iron (HDRI)‐based EAF steelmaking, carbon boiling is absent; therefore, carbonaceous material and oxygen injection into the slag is needed to maintain foaming and avoid nitrogen ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Transition Metal‐Regulated Ultraviolet–Visible–Near‐Infrared Absorption and Photothermal Conversion of Protocatechuic Acid/Ethylene Glycol‐Based Low‐Melting Mixture Solvents

Chemistry–Methods, Volume 6, Issue 10, October 2026.
A series of transition M‐LoMMSs containing Fe3+, Cu2+, and Co2+ were prepared using protocatechuic acid and ethylene glycol (PCA/EG). The prepared LoMMSs also showed reproducible photothermal responses during repeated heating–cooling cycles. Overall, the results demonstrate that the transition‐metal species significantly influence the optical ...

1,3‐Bis(tetrylene)s: Emerging Platforms for Functional Main‐Group Molecules

European Journal of Inorganic Chemistry, Volume 29, Issue 28, 1 October 2026.
Bridge design governs the stability and reactivity of 1,3‐bis(tetrylene)s. This review surveys pnictogen‐, chalcogen‐, and tetrel‐bridged systems and shows how geometric preorganization and electronic communication can enable cooperative bond activation and access to unusual heavy‐element π frameworks. Main‐group chemistry has undergone a resurgence as
