Piperoxan, also known as benodaine, was the first antihistamine to be discovered. This compound, derived from benzodioxan, was prepared in the early 1930s by Daniel Bovet and Ernest Fourneau at the Pasteur Institute in France. Formerly investigated by Fourneau as an α-adrenergic-blocking agent, they demonstrated that it also antagonized histamine-induced bronchospasm in guinea pigs, and published their findings in 1933. Bovet went on to win the 1957 Nobel Prize in Physiology or Medicine for his contribution. One of Bovet and Fourneau's students, Anne-Marie Staub, published the first structure–

MediaGuard is a conditional access system for digital television developed by SECA (Société Européenne de Contrôle d'Accès; renamed to Canal+ Technologies SA) (CEO François Carayol), a subsidiary of Canal+ Group, sold to Thomson (CEO Thierry Breton). Then Canal+ Technologies SA was broken in two pieces by Thomson in 2003, the MediaGuard sold to Nagra France and the MediaHighway to NDS France.

SolidSail, sometimes referred to as Solid Sail or SolidSail Mast Factory (SMAF) in reference to the eponymous subsidiary, is a wind propulsion technology designed for large vessels, developed by Chantiers de l'Atlantique in Saint-Nazaire, France. This innovative system is based on rigid sails made of composite materials and a tilting gaff rigging, enabling hybrid or primary wind propulsion for commercial and cruise ships. It is also the name of the subsidiary created by Chantiers de l'Atlantique in 2023.

Vitrimers are a class of plastics, which are derived from thermosetting polymers (thermosets) and are very similar to them. Vitrimers consist of molecular, covalent networks, which can change their topology by thermally activated bond-exchange reactions. At high temperatures, they can flow like viscoelastic liquids; at low temperatures, the bond-exchange reactions are immeasurably slow (frozen), and the Vitrimers behave like classical thermosets at this point. Vitrimers are strong glass formers. Their behavior opens new possibilities in the application of thermosets, such as a self-healing mat
