Daniel Beysens is the Honorary Director of Researches at the PMMH laboratory (Physique et Mécanique des Milieux Hétérogènes), a joint laboratory of CNRS (Centre National de la Recherche Scientifique) and ESPCI–PSL (Ecole Supérieure de Physique et Chimie Industrielle – Paris Sciences et Lettres). He is the President – founder of the OPUR International Organization for Dew Utilization and was President of the European Low Gravity Research Association. His area of expertise is phase transition, e.g. in space, to improve the management of fluids, or to condense water from the air on surfaces to provide a new source of potable water. He was awarded various prizes and honors in Physics and Environmental Sciences.

This presentation was in continuation with “the physics of sterilization” in the core program of the congress. It explained how H₂O₂ interacts with germs at atmospheric and in vacuum.

Nicolas Lavielle graduated with his PhD at ETH Zurich in the domain of materials science and interfaces.
He, then, was a postdoctoral fellow at the Univeristy of Toronto and ESPCI Paris, working on non-adhesive materials for water and bacteria.
His expertise fields are physical-chemistry of polymers, soft matter and physics at interfaces.

This presentation will be in continuation with “the physics of sterilization” in the core program of the congress. It will explain how H₂O₂ interacts with germs at atmospheric and in vacuum.

Philippe DESTREZ is R&D Director at ASP. He is an active member of several ISO and EN standard committees including the H₂O₂ LTS working groups since their creation. He spends his all career in the medical device industry and has more than 20 years of experience in device reprocessing, disinfection, and prion research. He also contributed to the development of the French and WFHSS guidelines.

ISO 22441 was published in August 2022. We explained how the standard was developed, what it changes versus ISO 14937, and its links with the other H₂O₂ standards in progress
