Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

Safety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Frontiers in Acetylene Semi‐Hydrogenation: Advanced Catalyst Engineering and Mechanistic Unraveling for Ethylene Production

Safety Science and Technology, EarlyView.
The semihydrogenation of acetylene to ethylene represents a critically important catalytic process, which imposes stringent requirements on both catalyst design and reaction selectivity. This review provides a comprehensive overview of acetylene semihydrogenation through thermal catalytic, electrocatalytic, and photocatalytic pathways.

Five Decades of Dispute: A Triptych. E. J. Corey

The Chemical Record, EarlyView.
In his 2004 Priestley Medal address, E. J. Corey stated, “On May 4, 1964, I suggested to my colleague R. B. Woodward a simple explanation involving the symmetry of the perturbed (HOMO) molecular orbitals for the stereoselective cyclobutene/1,3‐butadiene and 1,3,5‐hexatriene/cyclohexadiene conversions that provided the basis for the further development ...

Five Decades of Dispute: A Triptych. Roald Hoffmann

The Chemical Record, EarlyView.
This article examines the historical Corey–Woodward controversy through Roald Hoffmann's personal perspective, completing a triptych on the prolonged dispute. Drawing on archival records, contemporaneous correspondence, and extensive interviews, it reconstructs Hoffmann's interactions with Corey and Woodward from the 1960s onward.
