EARTH: A New Way to View the Blue Sky
When Irish physicist John Tyndall was conducting research on why the sky is blue, he explored the notion with awe, for the pure sake of the idea. As he performed his experiments at The Royal Institution in London, in 1869, he likely did not foresee that his work would inspire generations of scientists and entrepreneurs who would adopt the term “blue sky” to explain the tenets of basic research.

Atmospheric Barriers: New Study Challenges Link Between Common Refrigerants and the Formation of TFA
A new EARTH study finds no evidence that the refrigerant HFC‑134a forms TFA under real atmospheric conditions. Simulations show proposed pathways are not energetically feasible, suggesting HFC‑134a is unlikely to be a direct source of TFA. Researchers will continue exploring other possible pathways.

EARTH researchers published a new study evaluating low-GWP refrigerants, specifically HFC-32/HFO-1234yf mixtures, as alternatives to R-410A. Their modeling shows that blends such as R-454B and pure HFC-32 can significantly improve energy efficiency, reduce emissions, and lower operating costs. The work supports the cooling industry’s transition toward cleaner, next-generation refrigerants.

Kevin Turner, a PhD candidate in Chemical Engineering at the University of Kansas, was featured on the cover of Industrial & Engineering Chemistry Research for his collaborative study on refrigerant flammability limits conducted with Hudson Technologies. His work advances safer and more sustainable cooling solutions.
