The Royal Swedish Academy of Sciences in Stockholm announced the laureates for the Nobel Prize in Chemistry on Wednesday, honouring 95-year-old French researcher Henri B. Kagan alongside Japanese scientist Kenso Soai. The duo received the prestigious international honour for their ground-breaking work in deciphering the enigmatic mirror-image structures present in chemical molecules and formulating remarkable chemical reactions in the process. Their discoveries effectively solved an intricate molecular puzzle that had baffled the scientific community for more than a hundred years.
Cracking the Centurylong Homochirality Puzzle
The core of their recognised work centers around resolving the mystery of molecular symmetry and asymmetry. Heiner Linke, who leads the chemistry branch of the Nobel Committee, underscored that the research conducted by Henri Kagan and Kenso Soai illuminated the mechanism by which uniform mirror-image chemical architectures can assemble spontaneously, an attribute identified in chemistry as homochirality. Commending their scientific breakthrough, Heiner Linke noted that Henri Kagan and Kenso Soai delivered the solution to a chemical puzzle spanning more than a century through reactions that proved truly magnificent.
Profiles of the Laureates and the Call from Stockholm
Both laureates represent prominent academic institutions across Europe and Asia. Henri B. Kagan, achieving this milestone at 95 years of age, is based in France and holds long-standing ties to Université Paris-Sud situated in Orsay. On the other hand, Kenso Soai is affiliated with the Tokyo University of Science in Japan. When the Nobel officials placed their official congratulatory call to Tokyo, Kenso Soai was out running errands and shopping near his residence.
Context of Previous Innovations and Ongoing Nobel Week
The latest announcement follows a strong continuum of chemical and physical breakthroughs celebrated on the global stage. During the previous year, the chemistry prize went to a group of three scientists who engineered novel molecular cages capable of entrapping substantial volumes of gases. That framework offers significant promise for trapping atmospheric greenhouse gases and extracting precious moisture within arid desert environments. The current Nobel season commenced on Monday with the physiology or medicine category, honoring three pioneers whose optic-based approaches enabled researchers to map brain operations with light. Following that, Tuesday brought the physics prize to Francis Halzen for illuminating the enigmatic nature of a rare class of neutrinos.
Remaining Schedule and Financial Purse for Winners
The roster of global honours continues over the coming days from the Swedish capital. The Nobel Prize in Literature is scheduled for unveiling on Thursday, followed by the highly anticipated Nobel Peace Prize on Friday. The sequence of announcements will conclude on the following Monday when the Nobel Memorial Prize in Economic Sciences is revealed. For the current cycle, each award carries a financial endowment of 12 million Swedish kronor, translating to approximately 11.6 crore rupees, which can be allocated to a single recipient, split within a small collective, or conferred upon an organisation.
