Chinese scientists have proposed a comprehensive process for the production of more environmentally friendly fifth-generation fluorinated materials. These materials are intended to replace refrigerants, blowing agents and solvents that are currently harmful to the environment. This was reported by Science and Technology Daily, a partner of TV BRICS.
According to one of the lead researchers, this research and development (R&D) effort does not simply involve replacing one compound with another but rather establishes a comprehensive system spanning molecular design, industrial production and environmental assessment.
The research team has proposed a new approach – using quantum chemical calculations and molecular modelling to synthesise compounds from scratch. The primary screening criterion was the avoidance of trifluoroacetic acid (TFA), a persistent pollutant that accumulates in water and poses a threat to ecosystems.
As the scientists explained, the fundamental aim of this work is to "tame" fluorine – one of the most chemically reactive and "challenging" non-metallic elements. Using molecular modelling and catalytic processes, they have successfully synthesised a series of novel compounds that are stable in performance and do not cause environmental problems.
Previously, the global fluoride industry had undergone four phases of substitution, but each solution to one problem brought about another. The new generation of materials, however, simultaneously addresses the major environmental issues inherent in previous generations: ozone depletion, high greenhouse gas potential and the formation of long-lived toxic metabolites.
Building on this new breakthrough, Chinese scientists are proposing their own "roadmap" aimed at driving a global transition towards environmentally friendly fluorides.

Ashok MondalNID Director"Signing this Memorandum of Understanding between the National Institute of Design (NID) and TV BRICS marks a pivotal milestone in advancing design diplomacy across the BRICS media space. This moment is especially significant as India hosts the 18th BRICS Summit, following India’s assumption of the BRICS chairship under the visionary leadership of Prime Minister Shri Narendra Modi. The partnership directly embodies his call to elevate Indian design standards through 'Design in India, Design for the World'. Through the global reach and broadcast capabilities of TV BRICS, we are excited to showcase the extraordinary visual storytelling, films, and design research of NID’s Film and Video Communication students to an international audience, while also welcoming and screening film works from BRICS network countries at NID Ahmedabad. This reciprocal exchange strengthens our shared commitment to educational, cultural, and artistic collaboration, fostering sustainable connections among global creative communities. NID Ahmedabad looks forward to leveraging this partnership to deepen cross-cultural dialogue, build international expert networks, and unlock transformative opportunities for filmmakers, researchers, and faculty across member nations" -
