So, yesterday, I spoke about titanium dioxide– memories that were triggered by this new article. Research performed by Drs. J. Mandal (he earned his PhD in Applied Physics at Columbia; now he is a postdoc at UCLA), Y. Yang and N.Yu (Columbia), as well as A.P. Raman (UCLA). Their paper, Paints as a Scalable and Effective Radiative Cooling Technology for Buildings, was published in the journal, Joule.
