Nature Reviews Chemistry, 2021
Fifty years ago, Kochi reported the iron-catalysed cross-coupling of alkenyl halides and alkyl Grignard reagents. Sparking a cross-coupling revolution, we reflect on the impact of this achievement and the importance of iron in the development of cross-coupling catalysis.

Abstract Forging is a deformation process achieved through the application of compressive stresses. During the stroke, pressures and velocities are continuously changing and the initial lubricant supply must suffice for the duration of the operation.

IEEE Journal on Selected Areas in Communications, 1993
The development of the fiber distributed data interface (FDDI), a 100-Mb/s token ring that uses optical fiber that has become the premier high-speed local area network (LAN) standard, is examined. The important decisions that shaped FDDI are described.

Manufacturing of Precision Forgings by Radial Forging
AIP Conference Proceedings, 2011Radial forging is a multi purpose incremental forging process using four tools on the same plane. It is widely used for the forming of tool steels, super alloys as well as titanium‐ and refractory metals. The range of application goes from reducing the diameters of shafts, tubes, stepped shafts and axels, as well as for creating internal profiles for ...

Forges prédatrices, forges protectrices
Revue géographique des Pyrénées et du Sud-Ouest, 1984La sidérurgie française se nourrit de bois, jusqu'au milieu du XIXe siècle au moins. Cette consommation pèse lourdement mais inégalement sur les forêts dont elle accélère la conversion. Les besoins en combustible végétal, la montée des coûts incitent les maîtres de forges à économiser le bois et à gérer prudemment leurs forêts.
