Thermodynamics of aqueous perfluorooctanoic acid (PFOA) and 4,8-dioxa-3H-perfluorononanoic acid (DONA) from DFT calculations: Insights into degradation initiation

Autor: Walter Navarrini, Maurizio Sansotera, Alberto Baggioli

Publikováno v: Chemosphere. 193:1063-1070

Modern fluorosurfactants introduced during and after perfluoroalkyl carboxylates/sulfonates phase-out present chemical features designed to facilitate abatement, hence reducing persistence. However, the implications of such features on environmental

A superrepellent coating with dynamic fluorine chains for frosting suppression: effects of polarity, coalescence and ice nucleation free energy barrier

Autor: Walter Navarrini, Takeo Moriya, Takeshi Matsubayashi, Ken Suwabe, Hirotaka Tsuchiya, Seimei Shiratori, Mizuki Tenjimbayashi, Kengo Manabe

Publikováno v: RSC Advances. 6:92197-92205

Ice formation on surfaces is a serious issue in many different fields in terms of function, safety, and cost of operation in human life. Hydrophobic coating technology is one of the effective ways to prevent ice formation. Previous studies focused on
